Correct Answer
B. Was lightweight and easy to move aroundExplanation
The first electronic digital computer was not lightweight and easy to move around. This is because the first electronic digital computer, known as the ENIAC, was huge and weighed about 30 tons. It occupied a large room and required a lot of space for its operation. Therefore, it was not designed to be easily portable or moved around.Rate this question:

What device is an example of an input device?
- A.
Microphone
- B.
Printer
- C.
Monitor
- D.
CPU
Correct Answer
A. MicrophoneExplanation
A microphone is an example of an input device because it allows users to input audio into a computer or recording device. It converts sound waves into electrical signals that can be processed and stored. This makes it possible to record voice, music, or any other sound and use it as input for various applications such as voice recognition, audio recording, or video conferencing. Unlike printers, monitors, and CPUs, which are output or processing devices, a microphone specifically functions to input audio data into a system.Rate this question:

Which of the following is not a type of auxiliary storage?
- A.
Flash Drive
- B.
Hard Drive
- C.
CD-ROM
- D.
RAM (Memory)
Correct Answer
D. RAM (Memory)Explanation
RAM (Memory) is not a type of auxiliary storage because it is a form of primary storage in a computer system. Auxiliary storage refers to external devices used to store data and programs, while RAM is used for temporary storage of data that is actively being used by the computer's processor. Flash drives, hard drives, and CD-ROMs are all examples of auxiliary storage devices that can be used to store data for long-term or offline use.Rate this question:

How would the CPU be represented in the human body?
- A.
Legs
- B.
Brain
- C.
Hands
- D.
Eyes
Correct Answer
B. BrainExplanation
The CPU (Central Processing Unit) is the main component of a computer that performs most of the processing inside the system. In the human body, the brain acts as the central processing unit. It is responsible for controlling and coordinating various bodily functions, processing sensory information, and executing complex tasks. Just like the CPU in a computer, the brain plays a crucial role in processing and interpreting information, making it the most appropriate representation of the CPU in the human body.Rate this question:

What was the name of the first personal computer?
- A.
Apple II
- B.
Apple I
- C.
Altair 8800
- D.
Apple III
Correct Answer
C. Altair 8800Explanation
The Altair 8800 is considered to be the first personal computer because it was the first commercially successful microcomputer kit. It was released in 1975 by Micro Instrumentation and Telemetry Systems (MITS). The Altair 8800 had an Intel 8080 microprocessor and was sold as a build-it-yourself kit. It gained popularity among hobbyists and computer enthusiasts, marking the beginning of the personal computer revolution. Apple I and Apple II were also early personal computers, but they were released after the Altair 8800. Apple III was released even later and had limited success in the market.Rate this question:

Input, Process, Output and Storage combine to make what cycle?
- A.
Computer Cycle
- B.
Input/Output Cycle
- C.
Data Storage Cycle
- D.
Information Processing Cycle
Correct Answer
D. Information Processing CycleExplanation
The combination of Input, Process, Output, and Storage in a computer system is known as the Information Processing Cycle. This cycle represents the flow of data and information within a computer system. Input refers to the data that is entered into the system, Process involves the manipulation and transformation of this data, Output is the result or information that is produced by the system, and Storage is the retention of data for future use. The Information Processing Cycle encompasses all these stages, illustrating how data is processed and transformed into meaningful information.Rate this question:

What device stores your pictures, music, applications and videos on a personal computer system?
- A.
RAM
- B.
ROM
- C.
CPU
- D.
Hard Drive
Correct Answer
D. Hard DriveExplanation
A hard drive is a device that stores pictures, music, applications, and videos on a personal computer system. It is a non-volatile storage device that retains data even when the computer is turned off. Unlike RAM (Random Access Memory) and ROM (Read-Only Memory), which are temporary and permanent storage respectively, the hard drive provides long-term storage capacity for various types of files. The CPU (Central Processing Unit) is responsible for executing instructions and performing calculations, but it does not directly store files.Rate this question:

When you open a program or play a game all information is stored in this location until it is saved to a more permanent location. Hint: Your computer may run slow if you don't have enough of this item installed.
- A.
RAM
- B.
ROM
- C.
CPU
- D.
Hard Drive
Correct Answer
A. RAMExplanation
RAM stands for Random Access Memory. When you open a program or play a game, all the information is temporarily stored in RAM until it is saved to a more permanent location, such as the hard drive. RAM is a type of computer memory that allows for quick access to data, and having enough RAM installed is crucial for smooth operation of programs and games. If you don't have enough RAM, your computer may run slow as it struggles to handle the demands of the software being used.Rate this question:

If your computer will not come on what should be checked first?
- A.
RAM
- B.
Power
- C.
ROM
- D.
Network Cable
Correct Answer
B. PowerExplanation
If the computer will not come on, the first thing that should be checked is the power source. This is because if there is no power supply, the computer will not be able to turn on. It is important to ensure that the power cable is properly connected to both the computer and the power outlet, and that there is electricity flowing to the outlet. By checking the power source first, any potential power-related issues can be identified and resolved, allowing the computer to turn on successfully.Rate this question:
