What would I use to connect my router to my cable modem?
- A.
Software
- B.
A telephone
- C.
An ethernet cable
- D.
A social network
Correct Answer
C. An ethernet cableExplanation
To connect a router to a cable modem, you would use an ethernet cable. An ethernet cable is a type of wired connection that allows for high-speed data transfer between devices. It is commonly used to connect devices such as routers, modems, computers, and gaming consoles. In this case, the ethernet cable would be used to establish a physical connection between the router and the cable modem, allowing the router to receive internet connectivity from the modem and distribute it to other devices on the network.Rate this question:

- C.
Basic Interference Outline System
Correct Answer
A. Basic Input/Output SystemExplanation
BIOS stands for Basic Input/Output System. It is a firmware that is responsible for initializing and controlling the hardware of a computer system. It provides the necessary instructions for the computer to start up and communicate with the various hardware components, such as the keyboard, mouse, and hard drive. The BIOS also performs a power-on self-test (POST) to check the system's hardware and ensure that it is functioning properly before handing over control to the operating system.Rate this question:

10 (ten)
- B.
1,000 (one thousand)
- C.
1,000,000 (one million)
- D.
1,000,000,000 (one billion)
Correct Answer
C. 1,000,000 (one million)Explanation
One megabyte (MB) is equal to 1,000,000 bytes. This is because the prefix "mega" in the metric system denotes a multiplier of one million. Therefore, 1MB contains one million bytes.Rate this question:

About how many megabytes does a CD ROM hold?
- A.
1 MB
- B.
100 MB
- C.
650 MB
Correct Answer
C. 650 MBExplanation
A CD ROM can hold approximately 650 megabytes of data. This is the correct answer because CD ROMs typically have a storage capacity of 650 MB, which allows for the storage of a significant amount of data, such as audio files, videos, or documents.Rate this question:

RAM is like ____________ while ROM is like _________________.
- A.
Short term memory; long term memory
- B.
Fading memory; long term memory
- C.
BIOS; Hardware
Correct Answer
A. Short term memory; long term memoryExplanation
RAM is like short term memory because it is used for temporary storage of data that is actively being used by the computer. It allows for quick access and retrieval of information, similar to how short term memory allows us to remember things temporarily. On the other hand, ROM is like long term memory because it stores permanent instructions and data that are essential for the computer's operation. It is non-volatile memory, meaning the data stored in it remains even when the computer is turned off, just like our long term memory retains information for a longer period of time.Rate this question:

There are 10,000 kilobytes (KB) in 1 megabyte (MB).
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because there are 1,000 kilobytes in a megabyte. Therefore, multiplying 1,000 by 10 gives us 10,000 kilobytes in 1 megabyte.Rate this question:

A normal Microsoft word file is about 30 megabytes (MB).
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
A normal Microsoft Word file is typically much smaller than 30 megabytes (MB). The size of a Word file can vary depending on the content, formatting, and embedded objects, but on average, a typical Word file is usually a few kilobytes to a few megabytes in size. Therefore, the statement that a normal Word file is about 30 megabytes is false.Rate this question:
-
- 14.
A minute of MP3 audio is about 1 megabyte (MB).
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is true because on average, a minute of MP3 audio is compressed to about 1 megabyte (MB) of file size. The compression algorithm used in MP3 format reduces the file size by removing some of the audio data that is less perceptible to the human ear. Therefore, it is possible to store approximately 1 minute of MP3 audio in a file that is around 1 megabyte in size.Rate this question:

A bit is...
- A.
The way computers store infrequently changing information like saved files and programs that are not in current use.
- B.
A binary digit taking the value of 1 or 0.
- C.
It allows the user to operate a computer with images rather than text commands.
Correct Answer
B. A binary digit taking the value of 1 or 0.Explanation
A bit is a fundamental unit of information in computing that represents a binary digit, which can have a value of either 1 or 0. It is the basic building block of digital data storage and processing, allowing computers to represent and manipulate information using binary code. This binary representation enables computers to perform calculations, store data, and execute instructions.Rate this question:

A byte is...
- A.
A series of 8 binary digits or 8 bits.
- B.
One billion bits.
- C.
The software between BIOS and applications. It is responsible for the management and coordination of programs.
Correct Answer
A. A series of 8 binary digits or 8 bits.Explanation
A byte is a unit of digital information that consists of 8 binary digits or 8 bits. It is the fundamental building block of computer data storage and processing. Each byte can represent a single character or a small piece of data. The binary digits within a byte can have two possible values, 0 or 1, which can be used to represent different combinations of data. Therefore, the correct answer is that a byte is a series of 8 binary digits or 8 bits.Rate this question:

ROM is...
- A.
The way computers store infrequently changing information like saved files and programs that are not in current use.
- B.
He place in a computer where the operating system, application, and data in current use are kept.
Correct Answer
A. The way computers store infrequently changing information like saved files and programs that are not in current use.Explanation
ROM, or Read-Only Memory, is a type of computer memory that stores information that is not meant to be changed or modified. It is used to store infrequently changing data such as saved files and programs that are not currently being used. Unlike other types of memory, the data stored in ROM is permanent and cannot be altered. It is typically used to store firmware or software instructions that are essential for the computer to function properly.Rate this question:
-
- 18.
RAM is...
- A.
The place in a computer where the operating system, application, and data in current use are kept.
- B.
The way computers store infrequently changing information like saved files and programs that are not in current use.
Correct Answer
A. The place in a computer where the operating system, application, and data in current use are kept.Explanation
RAM stands for Random Access Memory and it is a type of computer memory that is used to store data that is currently being used by the computer's operating system, applications, and other processes. It is a volatile memory, meaning that its contents are lost when the computer is powered off or restarted. RAM allows for quick and temporary storage of data, allowing the computer to access and process information quickly. It is different from storage devices like hard drives or solid-state drives, which are used to store data for long-term use.Rate this question:
