In this problem you will explore two algorithms for the problem of merging k sorted arrays, each containing n elements, into a s

ingle sorted array containing nk elements. The cost of merging an array of size a with an array of size b is a+b.
O The first algorithm merges two of the arrays, then merges in the third array, then merges in the fourth array, and so on.
1. We start by merging together two of the k arrays together, producing array M2. What is the cost of this merge?
2. We merge another of the k arrays with M2 from the previous question, producing M3. What is the cost of this merge?
O Now we'll consider a second algorithm. We are given k n-element arrays to merge. We recursively merge the first k/2 arrays, recursively merge the second k/2 arrays, and then merge the two results.
3. Imagine the recursion tree that results from this. We are sitting at the root of the tree. What is the cost of the merge done at the top of the tree?
4. What is the total cost of the two merges done at the second level of the tree?

Alexeev081 [22]

Answer: A central wireless access point (AP)

Explanation:

A central wireless access point (WAP) is a hardware device which can be configured on a local area network connecting WLAN to the wired network.

These APs have built in routers which enables wireless devices to connect with it. Mostly they are hardwired to devices such as in network switches or modems.

These access points are found in many institutions, organisations, enterprises which enables devices to be connected to them and provides access to the internet and resources.

There are also public access points which enables people travelling by public transport to connect through them and in many business organisation there are closed APs for use only by the employees of them which enables file sharing and information processing.

____________________ is like a set of instructions that helps hardware process data into information.
Arte-miy333 [17]

Answer:

Program

Explanation:

Program is like a set of instructions that helps hardware process data into information.

Every hardware needs a program to process data into information.

For example take the example of a data processing software like MS Excel.

You open a spreadsheet and enter some data into your sheet. and then ask the program to do some calculations with this data and give you output results. The spreadsheet software does this processing in the background for you and provides you the results.

Without program a hardware doesn't know what to do with the data. Therefore, a program is like a instruction set that guides the hardware what to do with the data.

Note: The terms software and program are usually used together but there is a difference between software and program

A software is a generalized term and program is more like a specific term.

software can be made up of several different programs which performs many different tasks. On the other hand, a program only carry out a specific task or set of instructions.
