Answer: computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems. ... In other definitions computer architecture involves instruction set architecture design, microarchitecture design, logic design, and implementation. e.g Computer architecture consists of three main categories. System design – This includes all the hardware parts, such as CPU, data processors, multiprocessors, memory controllers and direct memory access. This part is the actual computer system.

BartSMP [9]

Answer:

The correct answer to the following question will be Option C (Embedded).

Explanation:

An embedded system seems to be a monitoring system that incorporates a computer processor, device storage, and peripheral output/input devices that have a particular function within such a larger electrical or mechanical network.
Such devices are chips that are designed specifically and live within other devices or appliances.

The other three solutions can not perform tasks like the embedded computers do or even any other computer can implement the computer's processor. Therefore, it's the right answer.

In a batch operating system, three jobs are submitted for execution. Each job involves an I/O activity, CPU time and another I/O

Ilia_Sergeevich [38]

Answer:

a) CPU utilization for uniprogramming system = 18.2%

b) CPU utilization for multiprogramming system = 41.379%

Explanation:

IO time = total time – CPU time

For JOB 1

CPU time = 3ms ,

total time= 23ms

IO time = 23-3 = 20ms ,

For JOB 2

CPU time =5ms

total = 29ms

IO time = 29-5 = 24ms

For JOB 3

CPU time = 4ms

total = 14ms

IO time = 14-10 =10ms

1.) In uniprogramming system, operations are performed sequentially

CPU utilization=total CPU time / total real time

CPU utilization =(3+5+4) / (23+29+14)

CPU utilization =0.182 or 18.2%

2) In multiprogramming system, jobs wait for the CPU to get free while performing IO operations concurrently

steps followed by the os

1. IO for 1st job at 0ms

2. IO for 2nd job at 0ms

3. IO for 3rd job at 0ms

4. CPU time for 3rd job at 5ms

5. Next IO job for 3rd job at 9ms END at 14ms

6. CPU time for 1st job at 9ms

7. Next IO job for 1st job at 14ms END at 23ms

8. CPU time for 2nd job at 14ms

9. Next IO job for 2nd job at 15ms END at 29ms

CPU time is 3+5+4 =12ms

Total execution time = 29ms

CPU utilization = 12*100/29= 41.379%
