Answer:
Automation testing can be used for:
<u>Input-output test
:</u> If the main function of your software is to transform input data into output data you can configure a new test by providing a new input/output pair, then the test will check to see if the output matches with the expected values.
<u>Unit test
:</u> This test is a script to check the return values of a specific code by initializing it and calling his methods. This is a part of a test-driven development process.
<u>Integration test
:</u> This test is a code level script that does a complete check process involving multiple objects. For example, you might make a test for “buy a product” which checks to see if the database is updated, if the data is correct of the person is correct, and if the person placing the order gets the right confirmation email.
<u>Smoke Tests:</u> This test is executed immediately after implementation on production to ensure that the application is still functioning.
Virtual memory could be used to allow program 5 to access RAM without any of the data from the other four programs being lost because it is one that tend to allows the system to give all of the process its own memory space that is said to be isolated from the other processes.
<h3>How is virtual memory used instead of RAM?</h3>
A system is known to make use of a virtual memory and this is one that tend to make use of a section of the hard drive to act like the RAM.
With the use of virtual memory, a system can be able to load bigger or a lot of programs running at the same time, and this is one that tends to hep one to work as if it has more space, without having to buy more RAM.
Therefore, Virtual memory could be used to allow program 5 to access RAM without any of the data from the other four programs being lost because it is one that tend to allows the system to give all of the process its own memory space that is said to be isolated from the other processes.

Answer:
802.11ac
Explanation:
It is a wireless networking standard.It functions only on 5 Ghz only. 802.11ac has three times the bandwidth of 802.11n hence it can handle more number of users.It has multi-link throughput of 1 gigabit per second.It provides high throughput.It is very useful for environments with high user density.
Answer:
B.O(1)
Explanation:
When we are implementing ADT stack using linked chain we can pop an entry from the stack having O(1) time complexity because in linked chain we have the head or top pointer in linked chain only.Popping and pushing in stack happens on only one end that is top.So we have move to move top in linked chain to the next and delete prev node.
