The permanent memory that is built in your computer. This is read only
Explanation
ROM stands for Read-Only Memory. It is a type of permanent memory that is built into a computer. ROM is non-volatile, meaning it retains its data even when the computer is turned off. It is called "read-only" because the data stored in ROM cannot be easily modified or erased by normal computer operations. ROM is used to store firmware, which includes the computer's basic input/output system (BIOS) and other essential software that is required for the computer to start up.
2.
Choose computer input devices.
Correct Answer(s)
A. Mouse
D. Keyboard
F. Scanner
G. Compact Disc (CD)
H. Microphone
I. Digital Camera
Explanation
The correct answer includes Mouse, Keyboard, Scanner, Compact Disc (CD), Microphone, and Digital Camera. These devices are all examples of computer input devices. Input devices are used to enter data or instructions into a computer system. The mouse and keyboard are commonly used for inputting text and commands. A scanner is used to convert physical documents or images into digital format. Compact Discs (CDs) can be used as input devices to read and transfer data from CDs to the computer. A microphone is used to input audio or voice recordings, while a digital camera is used to input images or videos into the computer.
3.
Of the 4 words listed below, which one does NOT belong?
Correct Answer
B. Peripherals
Explanation
The word "Peripherals" does not belong because it is the only word that does not refer to a type of software or program. "Applications," "Programs," and "Software" are all terms used to describe different types of software, whereas "Peripherals" refers to external devices or hardware that are connected to a computer.
4.
Sound card is a small circuit board, required for high quality music, narration, and sound effects.
Correct Answer
A. True
Explanation
A sound card is indeed a small circuit board that is necessary for producing high-quality music, narration, and sound effects. It is responsible for converting digital audio signals into analog signals that can be played through speakers or headphones. Without a sound card, the audio quality may be poor and lack the necessary clarity and depth. Therefore, the statement that sound card is required for high-quality music, narration, and sound effects is true.
5.
What type of device is a computer monitor?
Correct Answer
B. Output
Explanation
A computer monitor is a type of output device. It displays the visual output of a computer, such as text, images, and videos, allowing users to view and interact with the information being processed by the computer. The monitor receives signals from the computer's software and translates them into a visual display that can be seen by the user. Unlike storage devices, which are used to store and retrieve data, a computer monitor does not have the capability to store information. Therefore, the correct answer is "Output."
6.
A small picture or symbol respresenting a computer hardware function or component.
Correct Answer
Icon, icon, icons, Icons
Explanation
The correct answer is "Icon". An icon is a small picture or symbol that represents a computer hardware function or component. Icons are commonly used in graphical user interfaces to provide visual representations of various functions or actions that can be performed on a computer. They help users easily identify and access different features or applications on their devices.
7.
CDs or DVDs is software device.
Correct Answer
B. False
Explanation
CDs or DVDs are not software devices. They are physical storage media used to store software or other data. Software devices refer to hardware components or peripherals that are specifically designed to run or support software, such as a printer or a scanner. CDs or DVDs themselves do not have the capability to run or support software on their own. Therefore, the correct answer is False.
8.
Which of the following is software?
Correct Answer
C. Antivirus
Explanation
Antivirus is considered software because it is a program that is designed to detect, prevent, and remove malicious software from a computer system. It is specifically developed to protect the computer from viruses, malware, and other harmful threats. Unlike the other options listed (mouse, keyboard, and monitor) which are hardware components, antivirus is a software application that can be installed and run on a computer to provide security and protection.
9.
Who is the inventor of computers?
Correct Answer
B. Charles Babbage
Explanation
Charles Babbage is considered the inventor of computers because he designed the first mechanical computer, known as the Analytical Engine, in the 19th century. Although the Analytical Engine was never built during Babbage's lifetime, his designs laid the foundation for modern computer systems. Babbage's work included concepts like punch cards for input and output, a control unit, and a memory system, which are fundamental components of computers today. His contributions to the field of computing make him widely recognized as the inventor of computers.
10.
Which of the following is the most powerful type of computer?
Correct Answer
B. Super computer
Explanation
A supercomputer is the most powerful type of computer. It is designed to perform complex calculations and process large amounts of data at incredibly high speeds. Supercomputers are used for tasks such as weather forecasting, scientific research, and simulations that require massive computational power. They have a much higher processing speed and storage capacity compared to microcomputers or mainframe computers, making them ideal for handling complex and resource-intensive tasks. Therefore, a supercomputer is the correct answer as it is specifically designed to provide the highest level of computing power.
