5 0

Hope this helps Synchronous messaging involves a client that waits for the server to respond to a message. Messages are able to flow in both directions, to and from. Essentially it means that synchronous messaging is a two way communication. i.e. Sender sends a message to receiver and receiver receives this message and gives reply to the sender. Sender will not send another message until get reply from receiver that's the definition of synchronous

salantis [7]

Answer:

(A) The CPU time for J1 is =2 ms other time is =18 ms, for J2 CPU time =6 ms other time = 24 ms, for J3 CPU time = 3 ms and other time = 12 ms (B) The CPU Utilization for uni-programming is 0.203 or 20.3% (C) For Multi-programming, when a program is not free and busy with an operation, the CPU is allocated to other programs.

Explanation:

Solution

Given that:

A(1)Job J1 = CPU time = 2ms

Other time =18 ms

Total time = 20 ms

(2)Job J2 = CPU time 6ms

Other time = 24 ms

Total time = 30 ms

(3)Job J3 = CPU time = 3ms

Other time =12ms

Total time = 15 ms

(B) For the CPU Utilization for uni-programming, we have the following as follows:

CPU utilization =The total time of CPU/The total real time

Thus,

=(2 +6+3) / (18+24+12)

= 11/54

=0.203 or 20.3%

(C) For the CPU utilization for multi-programming, when a program is not available that is busy in an operation, such as the input and output the CPU can be allocated or designated to other programs

Explanation:

Suppose you have a plenty of data in a spreadsheet. It has been found that if the rows and columns are being shown through color banding, then they look quite pleasant to our eyes. And the options for the columns and rows banding helps us in developing bands that are formed alternatively, and one being colored and the other being shaded. And all these are rows and columns. So we have banded rows and banded columns. And you can make this by converting the sheet to table, and then using the table style.
