Given a computer with a disk capacity of 16 GB and a word size of 32 bits, how many wordssize of 32 bits, how many words can be stored on the disk? Show your calculations.

· Represent the binary value 1101102 in hexadecimal. Show the steps of conversion that you used.

· Represent the hexadecimal value f616 in binary and decimal. Show the steps of conversion that you used.

· Explain why it is important to know how many system words will fit in a primary storage device on a computer (such as the hard drive).

· Explain why more information can be contained in multiple bytes joined together than in a single byte.

· Explain why it is more difficult to convert a decimal value to hexadecimal than it is to convert it to binary.

· Convert the number 327 to hexadecimal. Show the conversion steps you have taken. Hint: It is easier to convert the value to binary first and use the binary result to convert to hexadecimal.

· What is the ASCII hexadecimal code for a blank space? Why is it necessary to represent a blank space as a separate character in text?

· Using Microsoft Word or Excel, for the hexadecimal codes for the numbers from 0 through 9

· What are the binary and decimal values of the ASCII letter K? Show the steps of the conversion.

· Use the web to explore the Universal Character Set (UCS) - ISO/IEC 10646 - and explain why it was developed. Compare and contrast this system with ASCII. What is the relationship of ASCII to the UCS encoding?

· Using the ASCII encoding scheme, write my name "Eddie Johnson" in hexadecimal. How much memory would it take to store my name if each ASCII character occupied a byte?

· Using a word size of 64 bits, how much memory space is wasted by the leading 0 used to store 256 ASCII characters each in individual bytes? Justify your answer.

· What is the binary equivalent of the word NETWORK using ASCII encoding?

· Briefly define LAN, MAN, PAN, and WAN. What is the critical distinction for these networks? What is the classification metric used here?

· Briefly define the term network topology. What is the metric used to define networks by topology?

· What are some devices that you can connect to a PAN? And reason to support the answer.

· What are the limiting factors for grown mesh networks (adding new nodes)? What are the limiting factors for growing star networks? Justify the answer.

· Give an example of a MAN and describe why this type of network would be useful. Justify the answer.
