This assignment has been intended to permit students to test and express their ability to:
• Create XHTML documents using a basic text editor
• Develop XHTML documents using appropriate techniques
• Describe how common data structures work and where they are applied
• Write small code fragments in a simplified assembly language
Task 1
Using the Web as a resource for your investigation, find and elucidate what BAT files and shell scripts holds, and what they are used for. In the light of your findings, discuss why an operating system would offer both a graphical user interface and a command line interface.
Task 2
You have been asked to advise a small business of their network needs. The business utilises 3 offices in each of two building separated by a roadway approximately 15 metres wide. The offices are used by the 10 employees, 6 in one building and 4 in the other. The equipment required comprises desktop computers, printers, notebooks, shared storage and an internet connection. Each building has separate telephone connections.
Investigate alternatives.
Using the key terms from this topic, plan the network you would recommend and justify your choice of wired or wireless. Comprise in your discussion the components and type of network topology. Make sure you identify any assumptions in your design.
Task 3
The Little Man Computer (LMC) described in Study Guide has instructions for adding and subtracting integers however not for multiplying and dividing integers. The following pseudo code algorithm displays the quotient for a given dividend and a given divisor, that are related by dividend= quotient x divisor + remainder
It is supposed that none of these are negative and that the divisor is not zero. The algorithm is:
Prompt user for input
Set DIVIDEND = input value
Prompt user for input
Set DIVISOR = input value
Set QUOTIENT = 0
While DIVIDEND is greater than DIVISOR
DIVIDEND = DIVIDEND – DIVISOR
QUOTIENT = QUOTIENT + 1
Display QUOTIENT
Write assembly language code which implements this algorithm for the LMC. Use simulator at the LMC Home page to assemble and run your code for testing and correction. If that is not available there is a copy of the simulator at the Interact site for this subject, under Resources/LMC.
