An alternative to hexadecimal notation for representing bit patterns is dotted decimal notation in which each byte in the pattern is represented by its base ten equivalent. In turn, these byte representations are separated by periods. For example, 12.5 represents the pattern 0000110000000101 (the byte 00001100 is represented by 12, and 00000101 is represented by 5), and the pattern 100010000001000000000111 is represented by 136.16.7. Represent each of the following bit patterns in dotted decimal notation.
- a. 0000111100001111
- b. 001100110000000010000000
- c. 0000101010100000

- CPU contains a special bit called the overflow bit , denoted by V. When CPU adds two binary integers, if their sum is out of range when interpreted in 2's complement representation, then V is set to _____, otherwise V is set to _______.

Binary number: (For example, the decimal number 16 is the same as the binary number 10000; the decimal number 13 is the same as the binary number 1101.)arrow_forwardWorking with cell addresses The address of a cell in Google sheets can be specified in two ways: either as a letter-number pair like C5, or as a pair of numbers like "row 5, column 3". Some formulas may be easier to specify on one way or the other, so it's useful to know how to convert from one form to the other and back. ROW() and COLUMN() take addresses in A1 format and return the number of the row and column respectively. ADDRESS() takes numeric row and column inputs and returns the address in A1 format. It also has an option argument to specify the relativity of the addresses: 1 (the default) returns absolute addresses; 2, 3, and 4 return row absolute, column absolute, and relative addresses respectively. In this chapter you'll be working with Indian butterfly data from Singh and Pandey. Instructions In column H, get the row numbers of the Locality column. In column I, get the column numbers of that column. In column J, convert columns H and I back to addresses in $A$1…arrow_forward
- What would be the smallest possible value of n that will be enough? The Unicode family of character encodings uses a binary string of n bits to represent characters. Suppose that it is necessary to encode at least 100,000 distinct characters.arrow_forwardSuppose the following algorithm is used to encrypt a password A three-digit decimal number is input as the password Your Student ID last two-digit are added to this password Then it is converted to a binary number Then it is converted to 1's complement representation And lastly, it is converted to a Hexadecimal number Finally, this number is printed on the screen. What will be output if you input “786” in step 1 as a three-digit decimal number in the above algorithm?

- Consider the following floating point representation where each number has 2exponent bits and 5 fraction bits. The exponent bias is 1. Round each number tohave 3 fraction bits. Apply round-to-even and round-toward-zero modes.a. 1 10 11100b. 0 00 00101c. 1 01 10101i. Can you see a pattern for rounding floating point numbers when thenumber of exponent bits are intact?arrow_forwardIn HexWorld, instead of the decimal (base 10) number system we are used to, the hexadecimal numbersystem is used. The hexadecimal number system uses base 16 with digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E,F, (where A is 10, B is 11, C is 12, D is 13, E is 14, F is 15). To communicate with HexWorld when numbers areinvolved, we are asking you to help us by coding a Python program, in a file called convert_hex.py, torepeatedly request a positive decimal number from the user and output the hexadecimal value until there areno more decimal values to be converted. We will assume there are no negative values to be converted.To compute the hexadecimal value we have to find the hexadecimal digits hn, hn-1, hn-2, ..., h2, h1, and h0, suchthatdec_value = hn x 16n + hn-1 x 16n-1 + hn-2 x 16n-2 + ... + h2 x 162 + h1 x 161 + h0 x 160These hexadecimal digits can be found by successively dividing dec_value by 16 until the quotient is 0; theremainders are h0, h1, ..., hn-1, hn.For example, if…arrow_forwardShow Steps Please 5.
