A certain link layer interfaces uses CRC to detect errors. Answer the following questions. a. For each 8-bit data frame, the layer users a generator polynomial G(x0 = x^4 + x^2+ 1 to add redundant bits. What is the sequence of bits actually sent when the 8-bit data frame is "10011101"?

Please answer ASAP

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?

2. For each of the following, write the ONE correct answer. a) TCP/IP layers are Internet (I), Transport (T), Application (A), Physical (P), Network Interface (N). Which layer deals with modulation in WiFi networks? The layer whose header contains the source MAC address is Answer= Answer= b) The leftmost and rightmost bits in a byte are MSbit and LSbit respectively. For the 2 bytes 10000000 00000001, assume that the first byte is MSbyte and the second byte is LSByte. Assuming that bits are transmitted from left to right, write the transmission order that is bit big endian and byte little endian: Answer= c) Let TP=unshielded twisted pair, CC=coaxial cable, F=fiber, L=lasercommunication. Which of these media Uses a shield for limiting interference Achieves the highest bandwidth across long distances Answer= Answer= d) Of FDMA, CDMA, TDMA and SM (statistical multiplexing), which method is multiplexing primarily based on in LTE networks? Answer= e) Which particular form of FDM is used over…
