assembler language

Project 1

What is my assignment?

 

Getting Started (Items you have to review or learn to do for the project)

In order to get started on creating your assembler you must be able to have the program understand basic syntax of a text file containing a program.  In this first part of the program you will deal with the basic functions of string processing and reading files.  The following is a list of items to complete to help you do the project.

 

1) You will need to be able to read in arguments pass from the command line.

Ex: project1.exe inputfile.txt outputfile1.txt

 

2) You will need to be able to parse a string.

Ex: You will need to use the strtok() function in the string.h file.

 

3) You will need to convert all letters to lowercase letters.

 

4) You will need to compare a string to a list of know words.

(add, load, store, r0, r1, r2)

 

5) You will need to have a number in text 123 be converted to a number (integer) in the C program.

 

6) You will also need to be able to read and write files.

 

Project #1

Your assignment is to make a simple assembler for the DLX processor.  We will simplify the assembler by only using the core instructions, we will not do the floating point instructions.  The registers will be named as r0, r1, r2, … r29, r30, r31.  We will also not allow any advance naming for saving constant or memory locations the assembly source code we write will hard code any constant and memory location to read and write to.  The only advance item we will do is use a label for branching and jumping in code.

 

Items to turn in: a report that tells how you created your program, source code, test files and a flow chart.

 

Tips

It is common to run an assembler in a two pass structure.  The first pass goes through the source files and finds all the labels and addresses for each instruction.  You can start your program by assuming the first line of code is at memory location 0.  You will make a table of label and address.  On the second pass you will then convert the assembly instruction into machine code and fill in any labels using your table.

 

 

What to turn in

 

The following is what needs to be turned in for project 1:

Report

The report is made up of the following 4 parts:

1) The first part tells me if the project was successful or unsuccessful. If unsuccessful tell me which parts work and which parts do not work.

2) I need a documentation of each function of your code. Give me the name of the function, the inputs/outputs, and a description of what the behavior of the function is.

3) Instead of a flow chart give me a written set of steps that occur in your code design, reference the names of function calls as needed. You will write is as

Step 1 – what is done in step 1

Step 2 – what is done in step 2. If you have decisions write if X occurs go to step Y.

4) Project output. I need you to write a test file that test one instruction of each type (Load, Store, Branch, ALU, ALUi, JR, J). Write out the instructions in the test file and give me a screenshot of the output. Show the output of the encoding done by hand and compare it to the encoding of your program.

 

Source Code

 

Test Files (SubI r12,R20,255

start: lw r7,-16(R31)

SLT r3,r1,r9

BEQZ r1, STOP

SGTI r3,r7,-5

stop: sb 16(r11),r9

jalr r4

All of the files should be placed in one zip file. Name the file as P1_lastname.zip I do not want the files sent in an email. Post the file in blackboard under the Project 1 assignment. I will take

School of Science/ Computer Science and IT
ISYS1055/1057 Database Concepts
Assignment 1
Semester 1, 2017
1 Introduction
This is an individual assignment, to be submitted electronically using the Blackboard facility. A
submission link will be enabled on blackboard closer to the submission date. It is due 23:59 Friday
21st April 2017, and contributes 20% towards the aggregate of 100 marks.
The objective of this assignment is to reinforce what you have learned in the lectures and tute/ lab
sessions. Specifically, it covers the basic concepts in the relational database model, using entityrelationship
model for database design, and using SQL for querying a relational database.
1.1 Plagiarism
All code or other material that is not original must be fully credited. That is, any material that is
copied or derived from another source must be clearly identified as such and the original author
must be identified. Sometimes students assist each other with an assignment, but end up working
together too closely, so that the students’ separate solutions have significant parts in common;
unless the solutions were developed independently, they are regarded as plagiarised.
Plagiarism is a very serious offence. Any submissions determined to be a result of plagiarism will
be deemed as an academic misconduct and harsh penalties apply. It is also an offence for
students to allow their work to be plagiarised by another student. You should familiarize yourself
with the university website for Academic Integrity Policy, Procedures and Guidelines.
(http://www.rmit.edu.au/academicintegrity) All work is to be done individually and plagiarism of any
form will be dealt with according to the RMIT plagiarism policy.
1.2 What to Submit, When, and How
1.2.1 When
This assignment is due at 23:59 on Friday 21st April 2017.
1.2.2 What
You should submit one PDF document with all answers together. You can use Oracle SQL
Developer and LucidChart to work on your assignment. You may use Word or any other word
processor to compile your submission. At the end, convert it into PDF format. Do not submit Word
files. if that option is not available on your system there are free pdf converters online you can
utilise. e.g. http://convertonlinefree.com/
1.2.3 How
You are required to submit your solution electronically using the Blackboard facility. A submission
link will be enabled on blackboard closer to the submission date.

1.2.4 Penalties for late submissions
Late submissions of assignments will be penalised as follows. For 1 to 5 days late, a penalty of
10% (i.e. 10% out of total marks, not 10% out of your marks) per day. For assignments more than
5 days late, 100% penalty applies. If you submit between 00:00 22nd April and 23:59 22nd April,
your penalty is 10%. If you submit between 00:00 23rd April and 23:59 23rd April, 20% penalty, and
so on.
1.2.5 Special Consideration
If unexpected circumstances affect your ability to complete the assignment you can apply for
special consideration. If you seek a short extension, you can directly contact the lecturer. For
longer extensions, you must follow instructions provided at
http://www1.rmit.edu.au/students/specialconsideration
1.3 Preparation Tasks
Part A of this assignment, you must be familiar with LucidChart diagramming application. You are
required to complete the Week 4 Tute/ Lab session prior to attempt this assignment. Additional
resources on using LucidChart are available under Databases and Tools section of the course
Blackboard shell.
2 Part A: Entity-Relationship Modelling (50 Marks)
2.1 Designing an Entity-Relationship Model
You have just been employed as a database designer in a well-established software development
firm. Your first job is to design and implement a database system for a small medical centre in one
of the Melbourne suburbs.
The following information have been gathered after analysing the current practices of the medical
centre.
• The system records information about the doctors work at the medical centre. Doctors
have unique registration numbers. In addition to the registration number for each
doctor, the system records the name, date of birth, gender, qualifications, and
specialisations. Doctors can have multiple qualifications and multiple specialisations.
• The system keeps a record for each patient. When a new patient comes to the medical
centre, the patient is given a registration form to be filled. The information gathered in
this form will be stored on the system. When these information is entered to the system,
a serial number is assigned to each patient. The registration form captures following
information: name, address, date of birth, gender, telephone numbers (multiple
numbers are allowed), Medicare number (if any), private health cover number (if any),
and private health cover company (if any).
• When a patient attends a consultation with a doctor, following information are recorded:
consultation number, date, time, description, symptoms, and special remarks.
Symptoms is a multi-valued attribute.
• A number of prescriptions can be recommended after each consultation. For each
prescription, following information are recorded: name of the medicine, dosage, number
of repeats, and special instructions. None of these attributes are unique. However, for a
given consultation a medicine is prescribed only once.
• The doctors sometimes make referrals for other procedures, such as X-ray, MRI, and
physiotherapy. The system should be able to record such referrals made at
consultations. For each referral, following information are recorded: name of the
procedure, short description, referred practitioner, and whether this procedure essential

or optional. Like prescriptions, referral for a given procedure is only made once in a
consultation
• The system should be able to keep accounting information. In particular, the system
should be able to store payments made for the consultations. There are three
possibilities:
1. bulk-billing:
Some Medicare1 patients (such as disabled and seniors) are bulk-billed. This means
that the patient is not required to pay anything up-front. The medical centre will bulkbill
the Medicare (the government agency that deals with healthcare services in
Australia) the costs associated with the consultation. For such transactions, the
medical centre will record the payment number, timestamp, amount and the
Medicare reference number
2. full up-front payments (cash or card):
The patients with no Medicare benefits are required to pay full cost of the
consultation up-front. For such payments, the medical centre will record the
payment number, timestamp, the amount paid, and the method of payment.
3. settling part of the invoice using a Medicare benefits and the balance in cash or
card:
Some Medicare patients are required to pay a top-up payment (gap fee). That
means, part of the consultation fee is covered by Medicare benefits and the rest is
paid up-front by the patient. For such transactions, two payment records are created
and stored. (The both are linked to one consultation). First record will be similar to
(1) above. The second is similar to (2) above.
Based on the information you gathered, model the activities in your client’s business and present
your model as an Entity-Relationship diagram. Carefully state any assumptions that you make. In
your ER diagram, you must properly denote all applicable concepts, including weak or strong
entities, keys, composite or multi-valued attributes; relationships and their cardinality and
participation constraints.
If you cannot represent any of these information in the ER model, clearly explain what limitations in
the ER model restrict you from representing your model.
You must use UML notation used in the lectures and tute/ lab sessions. You may use any
diagramming tool to draw your diagram, however, use of LucidChart is highly recommended.
Your diagram must be drawn to a high standard with minimal clutter.
Note that you are not required to map the ER model to relational model.
A special note: This is an open-ended question with many different models can be derived. Your
model is assessed based on how accurately it represents business rules described above.
1 If you are not familiar with how Medicare works, http://www.mydr.com.au/first-aid-selfcare/

2.2 Mapping an ER Model to a Relational Database Schema
Consider the following E-R diagram, which models an online bookstore. Map this E-R diagram into
a relational database schema. Show every step of the mapping. No marks are awarded to the final
schema if you do not show the partially-built schema at the end of each step. Indicate the primary
key (underlined) and foreign key (with an asterisk) in each relation.

3 Part B: SQL (30 Marks)
LibraryDB is a database system that keeps track of information concerning the books and their
circulation in an imaginary library.
Disclaimer: The data that populates the database are artificially constructed and by no means
correspond to actual real-world data.
The schema for the LibraryDB database is given below.
The primary keys are underlined. The foreign keys are denoted by asterisks (*).
Description of the schema
• person — keeps track of the people who borrow books from the library. The attributes
contain personal and contact information.
• author — keeps track of personal information about authors.
• publisher — keeps track of the publisher information. To make simple, most of the attributes
have been truncated in the sample database.
• subject — this relation keeps information about the subjects on which the library collection
have books (such as Mathematics, Database, etc)
• book — contains information about the books that are available in the library. Every book
can have one or more physical copies in the collection. Each book can have one or more
authors and it is published by one or more publishers.
• book_copy — keeps track of the physical copies of the books in the library collection.
• borrow — keeps track of the check-ins and check-outs of the books. Every transaction is
done by one person, however may involve with one or more book copies. If there is no
return date, it means the book has been checked out but not returned.
• written_by — associates books with authors. A book may be associated with several
authors and an author may be associated with several books. There is also an attribute
‘role’ that specifies the role of the author for the book (author/ editor/ translator/ etc).
• published_by — associates publishers with books. There is an attribute ‘role’ here too.
• borrow_copy — associates physical copies of books with a transaction. Members are
allowed to borrow several books in a single transaction.
A conceptual data model (shown as an entity-relationship diagram) which represents these data is
given below.
borrow(transactionID, personID*, borrowdate, duedate, returndate)

4 Part C: Relational Database Model (20 Marks)
This question has been adopted from Fundamentals of Database Systems, Elmasri and Navathe.
(Question 5.11).
A relational database schema and an instance of this schema are given below.
Most of the attribute names are self-explanatory. Super_SSN refers to corresponding employee’s
supervisor’s SSN (Social Security Number). This example is based on US system, assume it is
similar to Australian Tax File Number.

Arrows indicate foreign keys and the corresponding attributes in parent relation. In the case of
Super_SSN, the parent relation is the Employee relation itself (self-referencing).
1. It was found that the data entry operator had incorrectly entered data for John B. Smith and
Ramesh K. Narayan. Their SSN were swapped. The error was discovered, and the data
entry operator was instructed to fix it. (S)he attempted to swap SSN value in each tuple
using the following SQL statement.
But, it was not successful. The DBMS returned an error message and two tuples were not
updated.
a) Explain why they didn’t work.
b) Give another way to correct the error.
c) Write down the correct SQL UPDATE statements to carry out your proposed solution.
2. James E. Borg gets a pay rise, which increased his salary by 10%. The data entry operator
has executed the following SQL statement.
Write down all the integrity constraints violated by the above operation. If the operation
does not violate any constraints, indicate as ‘no violations’.
3. Due to a workplace dispute, John B. Smith has been moved to a new supervisor. To effect
this change, the data entry operator has executed the following SQL statement.
Write down all the integrity constraints violated by the above operation. If the operation
does not violate any constraints, indicate as ‘no violations’.
4. A new project has been established, but neither a project number nor a department is
assigned yet. A new record has been entered into the Project relation, as follows.
Write down all the integrity constraints violated by the above operation. If the operation
does not violate any constraints, indicate as ‘no violations’.

Need Help-Hierarchical Network Design Assignment


Need Help-Hierarchical Network Design Assignment

Hierarchical Network Design Assignment

General Requirements

The college district is in the process of implementing an enterprise-wide network which will include Local Area Networks (LANs) at each site and a Wide Area Network (WAN) to provide data connectivity between all college sites.

Access to the Internet from any site in the college district is also an integral part of this implementation. Once the network is in place, the college district will implement a series of servers to facilitate online automation of all of the district’s administrative and many of the curricular functions.

Since this network implementation will have to continue to be functional for a minimum of 10 years, all design considerations should include a minimum of 20x (times) growth in the LAN throughput, 2x (times) growth in the WAN core throughput, and 5x (times) growth in the District Internet Connection throughput. The minimum requirement for initial implementation design will be Fast Ethernet to any host computer in the network and Gigabit Ethernet to any server host in the network.

 

 SECTION 1 – WIDE AREA NETWORK

The WAN will be based on a hierarchical model. Three (3) regional Hubs will be established at the Galway IT, Sligo IT and Letterkenny IT for the purpose of forming a fast WAN core network. College locations will be connected with
high-end, powerful routers. Access to the Internet or any other outside network connections will be provided through SligoIT with appropriate WAN links. For security purposes, no other connections will be permitted.

 

SECTION 2 – LOCAL AREA NETWORK & WIRING SCHEME

 

The LAN will include both wired and wireless connectivity.

Each Local Area Network (LAN) segment will use the appropriate Horizontal and Vertical Cabling which complies with TIA/EIA-568-A and TIA/EIA-569 standards.

Each College consists of 2000 student, 300 lecturers, 40 admin staff and 30 Network Technicians.  The LAN infrastructure will be based on Ethernet LAN switching. This will allow for a migration to faster speeds (more bandwidth) to the individual computers and between MDFs and IDFs without revamping the physical wiring scheme to accommodate future applications.

In each location a Main Distribution Facility (MDF) room will be established as the central point to which all LAN cabling will be terminated and will also be the point of presence (POP) for the Wide Area Network connection. All major electronic components for the network, such as the routers and LAN switches, will be housed in this location. In some cases an Intermediate Distribution Facility (IDF) room will be established, where horizontal cabling lengths exceed TIA/EIA-568-A recommended distances or where site conditions dictate. In such cases, the IDF will service its geographical area and the IDF will be connected directly to the MDF in a STAR or EXTENDED STAR topology.

Each room requiring connection to network will be able to support 24 workstations and be supplied with four (4) CAT 5 UTP runs for data, with one run terminated at the teacher’s workstation. These cable runs will be terminated in the closest MDF or IDF. All CAT 5 UTP cable run will be tested end-to-end for 100 Mbps bandwidth capacity. It will consist of a lockable cabinet containing all cable terminations and electronic components; i.e. data hubs and switches. From this location data services will be distribute within the room via decorative wire molding.

Wireless access should be secure allowing appropriate personnel to obtain connectivity with internet access.

SECTION 3 – DISTRICT SUPPLIED SERVERS AND FUNCTIONS

 

All file servers will be categorized as Enterprise or Workgroup type services, and then placed on the network topology according to function and anticipated traffic patterns of users.  You should select the appropriate files servers for the organisation along with the reasons for your selection.

SECTION 4 – ADDRESSING AND NETWORK MANAGEMENT

 

A complete TCP/IP addressing and naming convention scheme for all hosts, servers, and network interconnection devices will be developed and administered by the District Office. The implementation of unauthorized addresses will be prohibited. The District Addressing Scheme can be implemented in a number of ways. Ideas you should consider are Class A, B, and C Addresses with appropriate subnetting, Network Address Translation (NAT), and Private Network Numbers.

All computers located on the administrative networks will have static addresses, curriculum computers will obtain addresses by utilizing an appropriate server. Each site should use only addresses consistent with the overall District Addressing Scheme. A master network management host will be established at the Sligo IT college and will have total management rights over all devices in the network. This host will also serve as the router configuration host and maintain the current configurations of all routers in the network. Each region location will house a regional network management host to support its area. The management scheme for the data portion of the network will be based on the Simple Network Management Protocol (SNMP) standards. All routers will be pointed to the master Network Management host for the purpose of downloading new or existing configurations. The Sligo IT college will maintain the super user passwords for all network devices and configuration changes on these devices will be authorized from the District Office: i.e., Routers and LAN Switches.

 

 

SECTION 5 – SECURITY

External Threats – Internet Connectivity shall utilize a double firewall implementation with all Internet-exposed applications residing on a public backbone network. In this implementation all connections initiated from the Internet into the schools private network will be refused. Appropriate internal security should also be empolyed.

 

College Floor Plans

 

Each college floor plan is identical.   Make up your own plan based on the following.  Each college has 2 buildings 400 meters apart.

Building 1

2 floors

150 meters long

Each floor has 30 lecture theatres

POP is on floor 1

Building 2

1 floor

50 meters long

LAN Design Steps Study Guide

 

First step in LAN design is to establish and document the goals of the design

 

Requirements of network design:

  1. Functionality – provide user-to-user and user-to-application connectivity with speed and reliability
  2. scalability – ability for network to grow without major changes to overall design
  3. adaptability – design can adapt and implement new technologies as they become available
  4. manageability – easy network monitoring and management to ensure on-going stability

 

Critical components of LAN design:

  1. function and placement of servers – should use 100 Mbps or more
    1. servers provide file-sharing, printing, communication, and application services
    2. servers run specialized operating systems (netware, windows NT, UNIX, LINUX)
    3. categorized into 2 classes
  1. enterprise servers – supports all the users on network by offering services (e-mail, DNS); should be placed in MDF
  2. workgroup servers – supports specific set of users, offering services such as word processing and file sharing; should be placed in IDF
  1. select correct devices to decrease collisions
    1. media contention – excessive collisions caused by too many devices
  2. segmentation – splitting a single collision domain into two or more collision domains
    1. use bridges or switches creates more bandwidth availability
    2. bridges and switches forward broadcasts not collisions
    3. bridges and switches broadcast = FF-FF-FF-FF-FF
  3. bandwidth vs broadcast domains
    1. bandwidth domain is everything associated with one port on a bridge or switch also known as a collision domain
    2. all workstations compete for the same LAN bandwidth resource

 

1st step in designing a network is to:

  • gather data about the organizational structure
    • history
    • current status
    • projected growth
    • operating policies and management procedures
    • office systems and procedures
    • viewpoints of employees
  • analyze requirements
    • availability – measures the usefulness of the network
      • throughput
      • response time
      • access to resources
    • determine network traffic load
    • cost

 

2nd step in designing a network is to develop LAN topology (star/extended star)

  1. Layer 1 – physical cabling
    1. Type of cable (cat 5 for horizontal runs, fiber for backbone and risers)
    2. Distance limitations
  1. 100 meters for cat 5
    1. 3 meters – computer to telecommunication outlet/wall plate
    2. 90 meters – wall to horizontal cross connect (patch panel)
    3. 6 meters – HCC to switch
  2. 2000 meters for fiber
    1. make a logical topology diagram
  1. location of MDF and IDF
  2. type and quantity of cabling
  • detail documentation of all cable runs
  1. Layer 2 – devices to use to provide flow control, error detection, error correction, and reduce congestion
    1. Bridges
    2. Switches
  1. Can microsegment
  2. Eliminates collisions
  • Reduces size of collision domains
  1. Can allocate bandwidth on a per-port basis
    1. Asymmetric switching – allows more bandwidth to vertical babbling, uplinks, and servers.  Provides switched connections between ports of unlike bandwidth
  1. Layer 3 – use routers which:
    1. Allows communication between segments based on layer 3 addressing
    2. Allows connectivity to WANS
    3. Stops broadcasts from reaching other LAN segments
    4. Provides scalability
    5. Adds structure to layer 3 addresses
    6. Filters data-link broadcasts and multicasts

 

3rd step in designing a network is to create logical and physical network maps – document, by site and network within the site, the IP addressing scheme

 

 

 

 

 

Components of network documentation – least performed task in a network

  1. Cut sheet diagrams
    1. Diagrams that indicate the path of the physical wiring layout
    2. Type of cable
    3. Length of each cable
    4. Type of termination for each cable
    5. Physical location of each wall plate or patch panel
    6. A labeling scheme for easy identification of each wire
  2. MDF & IDF layouts – contains a physical and logical layout
    1. Rack mounts
    2. Auxiliary equipment
    3. Servers
    4. Patch panels
  3. server and workstation configuration details – fill out about each host attached to the network
    1. make and model of computer
    2. serial number
    3. floppy drives
    4. hard drives
    5. DVD/CD-Rom drives
    6. Sound and network cards
    7. Amount of RAM
    8. Physical location, user, and network ID
    9. Purchase date and warranty information
  4. software listings – of standard and special software
    1. operating system software
    2. application software
  5. maintenance records – all repairs to all equipment included in the network
  6. security measures
    1. soft security – user rights, password definition, firewall support
    2. physical security – how MDF and IDF’s are locked, who has access, how hosts are protected
  7. user policies – how users can interact with the network and consequences

 

Security policies

  • minimum password length
  • maximum password age
  • unique passwords
  • times of logon
  • don’t use family or pet names for passwords
  • screensaver password protected

 

Data recovery methods – protecting data from loss

  • Tape backup – duplicating all stored data to magnetic tape.  Works with a flag or switch. Uses an archive bit which only backs up what has been changes
    • pros – low cost
    • cons – stores data sequentially; drains system resources (bandwidth, processor power)
  • Fault tolerant disk configurations
  • Use of uninterrupted power supplies (UPS)

 

5 types of backup operations:

  1. full backup – all files on the disk are stored on tape and the archive bit for all files is set to off
  2. incremental backup – backup all files that have been created or modified since full backup; only work in conjunction with a full backup
  3. differential backup – backup all files like incremental backup but the difference is that even though the file is saved to tape, the archive bit is not reset, so each time differential backup is done, all files modified or created since the last full backup will be stored again
  4. copy backup – backup user selected files to tape; does not reset archive bit to off
  5. daily backup – backup only the files that are modified on the day of the backup; doesn’t reset archive bit to off

 

Fault tolerant storage devices – a redundant set of devices categorized by RAID (Redundant Array of Inexpensive Disks) levels 0 – 5

 

RAID types:

  1. RAID 0 – stripes data across multiple disks, no parity, no redundancy.  Used for speed
  2. RAID 1 – disk mirroring writes data to two identical partitions on separate hard disks thus creating an automatic backup.  Provides full redundancy but requires twice as much storage space
  3. RAID 2 – writes data across multiple hard disks, with error checking.  No longer used
  4. RAID 3 – stripes data one byte at a time and has a dedicated parity drive.  Very expensive
  5. RAID 4 – stripes data one sector at a time and has dedicated parity drive. Expensive and slow
  6. RAID 5 – stripes data and parity across multiple disks (at least 3).  A separate parity disk is not required abut full data redundancy is achieved.  On NT system, the boot and system partitions cannot be located on a RAID 5 disk array.  Very fast; need at least 5 disks for full redundancy

 

The three RAID levels that are supported by most operating systems are RAID 0, RAID 1, and RAID 5

 

Volume – a physical unit of storage

 

Environmental factors that can affect a network:

  1. Static
    1. caused by lack of humidity
    2. make sure all equipment is off
    3. make sure you ground yourself before starting to install equipment
  2. Dust and dirt
  3. Heat
  4. Power conditioning – preventing electrical irregularities
    1. Isolating transformer – controls voltage spikes and high frequency noise
    2. Regulators – maintains a constant output voltage.  Handles brownouts and surges
    3. Line conditioner – a regulator with an isolating transformer built in
    4. Uninterruptible power supply – battery charger that charges a batter, that in turn powers the computer
  5. EMI and RFI
    1. EMI includes power supplies and monitors, florescent lights, large electric motors, electrical wiring
    2. RFI (Radio Frequency Interface) picked up by other equipment or improper shielded cables
  6. Software Viruses
    1. Worm – propagates itself across computers, usually by creating copies of itself in each computer’s memory
    2. Virus – “infects” computer files (usually exe files) by inserting in those files copies of itself
    3. Trojan Horse – disguised as a game, a utility, or an application

 

Network performance – a measure of a networks quickness and reliability

  • Measured by a baseline – performance level established after the network has been installed and configured properly. Use a fluke LAN meter for a baseline
  • Baselines should be periodically updated

 

Two types of networks

  1. Peer-to-peer (workgroup network) – designed for small numbers of workstations (<10)
    1. Advantages
  1. Cheaper to create and operate
  2. Users control own resources
  • Doesn’t require a dedicated server
  1. No additional software required
    1. Disadvantages
  1. No central point of management
  2. If user changes password, all passwords on shared resources must be changed individually
  • If a shared computer is turned off, those resources aren’t available
  1. No room for growth
    1. Examples
  1. Windows for workgroups
  2. Windows 95
  • Windows 98
  1. LANtastic
  1. Client-Server – network operating systems
    1. Advantages
  1. Provide centralized point of user, security, and resource management
  2. Provide access to resources with one ID and password
    1. Disadvantages
  1. Single point of failure
  2. Requires specially trained personnel to maintain
  • Takes special network software and hardware

 

Client-Server operating systems:

  • UNIX
    • Kernel based
    • Uses NFS
  • Novell Netware (versions 3.12, 4.11, 5.0)
  • Windows NT

 

Main function of network operating system is to control the network by establishing:

  • Network user
  • Rights
  • Login accounts
  • Passwords
  • Groups
  • System profiles and policies

 

Troubleshooting a network

  1. identify network/user problem
  2. gather data about problem
  3. analyze data to come up with a possible solution
  4. implement solution
  5. if problem isn’t solved, undo change and modify data
  6. go to step 3

You should use the majority of skills that you have learned so far, like save/save as,  copy/paste,  doing bullets and numbering, inserting a date, a symbol, a picture  in a document, etc. (This would be a good summary for yourself. )

It is a good idea to use the snipping tool, cut and paste a piece of the menus of the Word, and refer to it.

Your Manual should be professionally prepared (at least 5 pages),  with

  1. Cover page,
  2. Table of content,
  3. The content which should have Major headings, and sub headings, etc.
