Complete Question:

The main disadvantage of using this device is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.

Group of answer choices

a. Router

b. Switch

c. Bridge

d. Hub

Answer:

d. Hub.

Explanation:

A hub can be defined as a layer one (physical) device used for connecting various network devices such as switches and routers in a local area network (LAN). It comprises of many ports which are used for connecting segments of a local area network (LAN). Hubs are generally considered to be unintelligent because when frames are received at a port, it is then copied to every other connected port on the network.

<em>Hence, the main disadvantage of using a hub is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.</em>

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%
