Suppose a file of 10,000 bytes is to be sent over a line at 2400 bps. A. Calculate the overhead in bits and time in using asynchronous communication. Assume one start bit and a stop element of length one bit, and 8 bits to send the byte itself for each character. The 8-bit character consists of all data bits, with no parity bit. B. Calculate the overhead in bits and time using synchronous communication. Assume that the data are sent in frames. Each frame consists of 1000 characters = 8000 bits and an overhead of 48 control bits per frame. C. What would the answers to parts (a) and (b) be for a file of 100,000 characters?

[8.3] Calculate by hand 8.625 × 10¹ divided by -4.875 x 10°. Show all the steps necessary to achieve your answer. Assume there is a guard, a round bit, and a sticky bit, and use them if necessary. Write the final answer in both the 16-bit floating-point format (1 for sign bit, 5 for exponent, and 10 for fraction) and in decimal and compare the decimal result to that which you get if you use a calculator.

In a Von Neumann architecture, groups of bits have no intrinsic meanings by themselves. What a bit pattern represents depends entirely on how it is used. The following table shows bit patterns expressed in hexadecimal notation i. 0x000940C2 ii. 0x8C90FFFC Qa)What decimal number does each bit pattern represent if,       i.It is a two’s-complement integer?       ii.It is an unsigned integer?   b) If each bit pattern represents an MIPS instruction, what instruction will be executed?   c) What decimal number does each bit pattern represent if it is a floating-point number in IEEE 754 standard?

internet Checksum. Consider the two sixteen bit numbers: 10110100 01000110 00001000 01101110 Compute the Internet Checksum of these two values Enter the 2 bytes each as an 8-bit number with only O's and 1's, and make a single blank space between the two 8-bit numbers (e.g., 01010101 00101000).

Internet Checksum. Consider the six sixteen bit numbers: 10110101 01000110 01001001 01101011 10110100 01000110 01001001 01101101 10110101 01010110 01011010 01101111 Compute the Internet Checksum field value of these six words (each word has sixteen bits) Enter the 2 bytes each as an 8-bit number with only O's and 1's, and make a single blank space between the two 8-bit numbers (e.g., 01010101 00101000). [Note: you must use bitwise XOR logic function and don't use 2's or 1's complement] Not quite. This answer is incorrect.

The type of encoding in which manipulation of bit streams without regard to what the bits mean is ..................... a. Destination encoding b. Entropy encoding c. Source encoding d. Differential encoding

Suppose the window of a data stream is as shown below. (Most recent bit is on the right side) Using the DGIM method, estimate the number of 1s in the last k positions, if k=24
