3 Two dimensional parity and CRC are two well-known techniques for error handling. There are few differences in the capability/strength of the each of the technique.- Explain with detail example.

Engineering, Computer Science / By

EXPERT ANSWER Step 1 3. Two dimensional parity:- For each row, parity check bits are calculated, which is identical to a basic parity check bit. For each column, parity check bits are computed and delivered together with the data. These are compared with the parity bits calculated on the received data at the receiving end. …

You are given a list of n jobs. Each job is executed in two steps: a preprocessing step followed by a production step. All the preprocessing is done sequentially on the same computer whereas the production steps of each job is done independently on a separate computer. Job i is represented by a pair (pi,fi) denoting the duration of the preprocessing and production steps, respectively. Devise a greedy algorithm to schedule the jobs on the common computer such that the completion time is minimum.

Example: Consider the jobs { (2,13),(4,2),(5,3)} and suppose we schedule them as they come: The first job finishes preprocessing at 2s, runs on a separate computer for 13 s and finishes at time=15s The second job finishes preprocessing at (2+4)s, runs on a separate computer for 2s and finishes at time=8s The third job finishes …

You are required to access any 5 HTTP objects (among them at least one should be an html, image, video and pdf objects). You are required to capture the HTTP request messages and their corresponding HTTP response messages through Wireshark or any other sniffing tool. With reference to corresponding HTTP RFCs, explain each header line of both the HTTP request and response messages.
