Character Encoding Essay

1. (TCO 4) Write the VBScript code that initializes all the variables in the numArray(100) to the value numArray(0)=1, numArray(1)=2,&#-123;,numArray(100)=101.

Character Data is how users translate words and phrases into a language computers understand and communicate back to said users in a universal presentation. Character data is made up of two things, characters and strings. First, alphabetic letters, numbers, and symbols are setup and defined in a specific way that the CPU can understand. All twenty six letters of the English alphabet are used, but only in an uppercase presentation. Basic numbers ranging from zero to nine are defined and used. From using just these ten numbers, we can create any other number the system may need to represent. These letters, numbers, and symbols individually are called characters. Any grouping of characters is called a string.

11. Which of the following answers best describes how a hard disk drive physically writes a binary 0

A bit is a single number or a single value which can be either 0 or 1 and this value is represent the digital information. A byte is a sequence of bits; like a sequence of digital information, usually eight bits equals to one byte.

3.1 Using the program shown in Figure 3.30 explain what the output will be at Line A.

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?

The parity bit is also used to restore the data because it matches the same parity bit that matches the data on other row and they can be used to restore the data.

the table $T_{vo}$ and table $T_{vc}$ shown as Figure~\ref{f:data structure access}(d) and Figure~\ref{f:data structure access}(e).

15. Which of the following answers is true about Ethernet MAC addresses? A) 48 bits in length C) Are listed

5. The check digit is the number which, when added to the total calculated in step 4, result in a

Between Wenshu and Puxian are seven small figures. They are set in three rows, with

This coding method helps to remove the redundancy between row vectors and column vectors of a block. For each 8 × 8 block RCRC generates r, which represents the row reference vector (RRV), and c, which represents column reference vector (CRV as cited in [1]. Vectors r and c may be viewed as 8-tuples which can acquire values 0 ≤ ri ≥ 1, 0 ≤ ci ≥ 1 and 1 ≤ i ≥ 8. A comparison between pairs of rows and columns from the block b is done in an iterative manner. The result of comparison gives the reduced vector. If the rows or columns of a given pair are identical, then the first pair of vector is kept for future use and the second pair of vector is eliminated, the second pair of vector corresponds to the duplicate pair. The final vector contains the reduced block. If the vectors in the given pair are not identical, then both of the vectors are preserved. The preserved vector pairs of rows and columns are stored in RRV and CRV,

2.) What is the value in the array element when the index contains 2? (Reference: array tutorial)

Let H = be the parity check Matrix of the triple error correcting BCH code where the order of the matrix is 3n by . The code C = [ , , d]is a code of dimension and minimum distance d= 7 between any pair of codewords.Generally we are interested in finding triples s.t. H is the parity
