The answer is provided in the form of explanation
Explanation:
A page fault occurs means that the required page is not in main memory. First OS check for
page in the cache memory, if the page is present then retrieved but if not present then check for
page in main memory and if the page is not present here too then it searches for page in hard
drive. To calculate the expected time, the following formula is used:
Cache hit ratio = 95% = 0.95
Cache miss ratio = 5% = 0.05
Cache access time = 2 millisecond
The average access time of hard drive = 30 milliseconds
Expected time = Hit ratio (cache access time +memory access time) + Miss ratio (cache
access time + 2 * memory access time)
= 0.95 (2+30) + 0.05 (2+2*30)
= 0.95 (32) + 0.05(62)
=30.4 + 3.1
= 33.5 millisecond
Expected time = cache hit ratio * cache access time + (1 – hit ratio) * cache miss ratio
= 0.95*2+(1-0.95)*0.05
= 1.9025
Well this isnt a computer and technology question ut ill still answer it... youve got being an IT person, Working at build- a-bear, laundry mat, babysitter, there is many different ones

Explanation:
Answer:
<em>Ethernet cables, Network Adapters, Modem, Routers, Switches.</em>
Explanation:
<em>The devices that are required in setting up a wired network for the 5 computer comprises of the following devices </em>
- <em>Ethernet Cables</em>
- <em>Network Adapters</em>
- <em>Modem/Router</em>
- <em>Network Switch</em>
<em>Ethernet cables: They are called network cables or RJ-45 cables used to in connecting two or more computers together. it has different categories called, the untwisted pair and twisted pair Ethernet, with a speed from 10-1000</em>
<em>Network Adapters : This adapters allows a computer device to connect and interface with a network computer</em>
<em>Modem/Routers : A router is a device that that sits in the middle between your local computers and modems. it takes receives information or gets information from the modem and delivers it to the computer</em>
<em>Network switch: it connects more than two computers together to a network and share data among themselves and other devices on the network</em>
