A level Computer Networks - Data Communication and Network Security Quiz 1

15 Questions

Quiz Description

In this quiz, we will be looking into computer networks based on Data communication between the network components and network security within these components. When using a computer network, computer networking will let you access the data from the other computers on the same network, and modify it according to your needs. computer networking, therefore, enables employees to share ideas more easily and work more efficiently regardless of where they may be.

A computer network can be defined simply to mean a set of interconnected computers all connected with the sole purpose of sharing information and resources between themselves. A good example is an internet, several computers are usually connected to the internet every single time, and all these computers share information and resources between themselves.

This quiz has a set 2 and set 3, be sure to check them out after this first quiz on Computer networks. Several other quizzes are available for free on our website, be sure to check them because they are worth it. 

Best of luck!
