Answer:

ICT is the abbreviated form of Information and Communication. It included different technologies like mobile phones, computers, USBs etc.

Following are two precautionary measures which should be observed when using any kind of ICT:

Use of Antivirus: It can used to protect anything placed inside the technology especially from hacking and viruses which can create many issues.
Backup Data: Creating a backup of the data stored in the device is important as it can be recalled when the device malfunctions. Backup of the data can be created through using USBs, CDs etc or through cloud storage

Matlab In this assignment you will write a function that will calculate parallel resistance for up to 10 parallel resistors. Cal

Ket [755]

Answer:

The complete Matlab code along with step by step explanation is provided below.

Matlab Code:

function Req=ParallelR(Number)

Number=input('Please enter the number of resistors: ');

if Number>10 | Number<=0

disp('Invalid input')

return

end

R=0;

for i=1:Number

r=input('Please enter the value of resistor: ');

R=R+1/r;

end

Req=1/R;

end

Explanation:

Parallel resistance is given by

$\frac{1}{Req} = \frac{1}{R_{1}} + \frac{1}{R_{2}} + \frac{1}{R_{3}}...+\frac{1}{R_{N}}$

First we get the input from the user for how many parallel resistors he want to calculate the resistance.

Then we check whether the user has entered correct number of resistors or not that is from 1 to 10 inclusive.

Then we run a for loop to get the resistance values of individual resistors.

Then we calculated the parallel resistance and keep on adding the resistance for N number of resistors.

Output:

Test 1:

Please enter the number of resistors: 3

Please enter the value of resistor: 10

Please enter the value of resistor: 20

Please enter the value of resistor: 30

ans = 60/11

Test 2:

Please enter the number of resistors: 11

Invalid input

Test 3:

Please enter the number of resistors: 0

Invalid input

Type which type of interference we will install after installing operating system

pentagon [3]

Answer:

There are different kinds of operating systems: such as Windows, Linux and Mac OS

There are also different versions of these operating systems, e.g. Windows 7, 8 and 10

Operating systems can be used with different user interfaces (UI): text user interfaces (TUI) and graphical user interfaces (GUI) as examples

Graphical user interfaces have many similarities in different operating systems: such as the start menu, desktop etc.

When you can recognize the typical parts of each operating system’s user interface, you will mostly be able to use both Windows and Linux as well as e.g. Mac OS.

THE ROLE OF OPERATING SYSTEM IN THE COMPUTER

An operating system (OS) is a set of programs which ensures the interoperability of the hardware and software in your computer. The operating system enables, among other things,

the identification and activation of devices connected to the computer,

the installation and use of programs, and

the handling of files.
