Lab 1.4 ASCII

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? 32. Spaces are part of data.
Using the Microsoft Word or Excel, create a chart similar to Table 1-3 for the hexadecimal codes for the numbers from 0 through 9.

Exercise 1.4.3
What are the binary and decimal values of the ASCII letter K? 01001011, 75.
What is the relationship of ASCII to the UCS encoding? For communication and exchange of electronic information. The way they encode each character and the number of bits used.
What features are provided by UTF- 8 that are not provided by ASCII? Why was it chosen to replace ASCII as the standard for the web? A variable with encoding that can represent every character in the Unicode character set. UTF-8 functions better on the web. It can translate foreign languages.

1. Using the ASCII encoding scheme, write your name (including the space between your first and last name) in hexadecimal. How much memory would it take to store your name if each ASCII character occupied a byte? 52-R, 61-a, 6D-m, 6F-o, 6E-n, 32-Space, 44-D, 65-e, 4C-L, 61-a, 54-T, 6f-o, 72-r, 72-r, 65-e. 1407/8= 175.875 bytes
2. 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? Every time you save a character it begins with 0 and only use 7 bits in a slot, so you would be wasting some money.
3. 3. What is the binary equivalent of the word NETWORK using ASCII encoding?
N= 01001110
