a) Sierra
b) Google
c) Edge
d) Outlook

3. To check TCP/IP configurations and IP connectivity, what are the two command-line utilities that can be used?

d) Ping and Ipconfig

4.  Choose the smallest memory size:

a) Kilobyte
b) Terabyte
c) Megabyte
d) Gigabyte

5.  Which of the following is a valid IP address?

b) 207.46.1
d) 207.46.645.5

6.  What part of a database holds only one type of information?

a) File
b) Record

7.  What is malware?

a) Any software downloaded over the internet that’s origin is unknown

b) A malicious software designed to harm or exploit any programmable device, service, or network

c) The master control program that manages a computer’s internal functions and provides a means of control to the system’s operation and file structure

d) A software run in the background of any computer system used to manage network connections

8. Select the email address from the choices below:


b) news@
c) D:\downloads\standard


9.  What is the brain of the computer? This is the part that does the calculating, moving, and processing of information.

a) CPU
b) Motherboard
c) Hard drive
d) Operating System

10.  Who invented the internet?

a) Ada Lovelace in 1843
b) Paul Baran and Donald Davies in 1960’s

c) Steve Wolff in 1986

d) Alan Turing in 1936


1. D – An IP address is a unique number associated with every system connected to a network, for example, is the IP address to

2. C – Edge is the only web browser listed in the available options. Google is a search website and a company name. Outlook is an email program, and Sierra is an operating system for Mac computers.

3. D – To check TCP/IP connectivity, you can use Ping and Ipconfig on a PC. These are utilities every tech support person uses regularly!

4. A – The smallest memory size among the options available is kilobyte. Memory size then follows with a megabyte, gigabyte, and terabyte.

5. C – A valid IP address must be in the form of A.B.C.D, where A, B, C, and D are numbers from 0-255. The numbers cannot be 0 prefixed unless they are 0.

6. C – A field is a data structure for a single piece of data within a database table. A record holds multiple fields. A file contains multiple records. Reports summarize information in the database.

7. B – Malware is a category of software that seeks to harm or exploit. Cybercriminals can use it to leverage financial gain over victims.

8. D – Email addresses must have an “@” symbol followed by a domain name to be valid.

9. A – The Central Processing Unit (CPU) is called the brain of the computer. It contains all the circuitry needed for processing input, storing data, and outputting results.

10. B – Independently, Paul Baran proposed a distributed network based on data message blocks, and Donald Davies conceived of packet switching and building a national commercial data network. In 1969, the U.S. Department of Defence awarded contracts for developing the ARPANET project, which used the packet switching technology proposed by Baran and Davies. Ada Lovelace was the world’s first computer programmer. Steve Wolff helped develop ARPANET but was best known for the development of IP networking at gigabit speeds allowing for the internet to be used for other purposes besides research. Alan Turing was the father of theoretical computer science and artificial intelligence.
