Complete Question:
Let's say that you handle the IT systems administration for your company. There's a server inside of your organization that checks how often client machines access it. If a client machine hasn't accessed the server in three months, the server won't allow the client machine to access its resources anymore. What can you set to make sure that your client machines and the server times are in sync?
Answer:
Network Time Protocol (NTP).
Explanation:
As the IT systems administrator, you can set the network time protocol (NTP) to make sure that your client machines and the server times are in synchronization.
A network time protocol (NTP) can be defined as an internet standard protocol which is used by an IT system administrator to synchronize a computer's clock to a particular time reference over packet switched or local area network (LAN) and variable-latency data networks. NTP was developed at the University of Delaware by Professor David L. Mills.
<em>Basically, the network time protocol uses the coordinated universal time (UTC) and a client-server model to measure the total round-trip delay for a computer process. </em>

Explanation:
A vertical merger is when two or more companies merge and are involved at different stages in the supply chain process for a common good or service. The merger is purposed to increase synchronism, gain more control of the supply chain process, and increase business. Also, it often results in reduced costs and increased productivity and efficiency.
A good example of a vertical merger is a auto manufacturer purchasing a tire company. A vertical merger of this sort reduces the cost of tires for the automaker and creates the possibility for expansion of its business by allowing it to supply tires to competing automakers.
Answer:
0.9961
Explanation:
Given that:
Proportion of time waiting for I/O operation to complete = 25% = 0.25
Number of programs waiting in memory = 4
Using the CPU Utilization formula :
CPU Utilization = 1 - p^n
1 - 0.25^4
1 - 0.00390625
0.99609375
