the computer. Always attempt to uninstall unnecessary applications, temporary

files, and antivirus software updates.

8. What is a Security Break?

Answer : Security break is leakage of information stored in a computer. Your

personal information can be lost or leaked in two ways – We are not cautious

when it comes to disclosing personal information via the internet. We share our

account information and passwords on unsafe websites. A person gets unauthorized

access to our computer. This can happen at work if we don’t log out before leaving

the computer.

9. How can we protect our data?

Answer : To protect our data from theft and viruses we can take the following

measures –

a. Use Strong password in your account – Make your passwords difficult to guess.

When creating a new password, attempt to use a combination of Small Character

Capital Character Special Character Numbers

b. Install Antivirus and Firewall –Anti-virus software and a firewall protect your

data from virus and from hackers.

c. Encrypt your data – Keep your information in an encrypted format to keep it

safe from unauthorized users.

d. Open only secure site – Before visiting a website, make sure the address begins

with https://. A website that begins with https:// is a secure website.

10. Difference between Hardware and Software?

Answer : A computer system consists of two main parts – Hardware and Software

a. Hardware – Hardware is a physical part of a computer system. We can feel

and touch the hardware devices. example – CPU, Mother Board, Hard Disk,

Keyboard, Mouse, Printer etc. b. Software – Software related to the programs

which perform different types of tasks on the computer system. Program is a

collection of Instructions. It also helps the computer to perform the specific task.

Example – Open Office Base, Spreadsheet, Presentation etc.
