1.

Computer is an electronic device that follows a set of instructions.
- A.
  
  True
- B.
  
  False
- C.
  
  Maybe
- D.
  
  None of the Above
Correct Answer
A. True

Explanation
A computer is indeed an electronic device that follows a set of instructions. Computers are programmed to execute specific tasks by following a series of instructions called a program. These instructions are stored in the computer's memory and are processed by its central processing unit (CPU). The CPU fetches each instruction, decodes it, and then executes it, allowing the computer to perform various operations and tasks. Therefore, the statement "Computer is an electronic device that follows a set of instructions" is true.

The computer accepts data, processes it, and presents the information.
- A.
  
  True
- B.
  
  False
- C.
  
  Maybe
- D.
  
  None of the above
Correct Answer
A. True

Explanation
This statement is true because computers are designed to accept input data from various sources, such as keyboards, mice, or sensors. Once the data is received, the computer processes it using its central processing unit (CPU) and other components, such as memory and storage. The processing involves performing calculations, executing instructions, and manipulating the data according to the program or user's command. Finally, the computer presents the processed information to the user through output devices like monitors, printers, or speakers.

It is also known as a personal computer and is mostly used.
- A.
  
  Mainframe
- B.
  
  Minicomputer
- C.
  
  Microcomputer
- D.
  
  None of the above
Correct Answer
C. Microcomputer

Explanation
A microcomputer is the correct answer because it is also known as a personal computer and is commonly used by individuals. This type of computer is smaller in size and is designed for personal use, such as for home or office use. It typically includes a microprocessor, memory, storage, and input/output devices. Microcomputers are widely used for various purposes, including word processing, internet browsing, gaming, and multimedia tasks.

It refers to the user or people who use and operate the computer system.
- A.
  
  Hardware
- B.
  
  Software
- C.
  
  Peopleware
- D.
  
  None of the above
Correct Answer
C. Peopleware

Explanation
Peopleware refers to the human users or people who use and operate the computer system. This includes individuals who interact with the hardware and software components of the system, such as programmers, operators, and end-users. Peopleware recognizes the importance of human factors in the successful functioning and utilization of computer systems. It emphasizes the need for effective communication, training, and management of the people involved in using and maintaining the system.

It is a sequence of 8 bits processed as a single unit of information.
- A.
  
  Bit
- B.
  
  Byte
- C.
  
  Kilobyte
- D.
  
  Megabyte
Correct Answer
B. Byte

Explanation
A byte is a unit of digital information that consists of 8 bits. It is the basic building block of computer storage and processing. Each byte can represent a single character or a small piece of data. Bytes are commonly used to measure file sizes and memory capacity in computers.

These are large general purpose computers.
- A.
  
  Mainframe
- B.
  
  Minicomputer
- C.
  
  Microcomputer
- D.
  
  None of the above
Correct Answer
A. Mainframe

Explanation
Mainframe computers are large general-purpose computers that are designed to handle a wide range of applications and tasks. They are typically used by large organizations and government agencies due to their high processing power, storage capacity, and ability to handle multiple users simultaneously. Mainframes are known for their reliability, scalability, and security features. Unlike minicomputers and microcomputers, which are smaller in size and have less processing power, mainframes are capable of processing large amounts of data and running complex applications efficiently. Therefore, the given answer "Mainframe" accurately describes the large general-purpose computers mentioned in the question.

A byte can be represented by a single character which can be:
- A.
  
  A letter
- B.
  
  A number
- C.
  
  A space
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
A byte can be represented by a single character, which means it can be any of the options mentioned: a letter, a number, or a space. Since a byte is a unit of digital information, it can be used to represent any of these characters. Therefore, the correct answer is "All of the above."

Five thousand (5,000) bytes is equivalent to:
- A.
  
  1 kilobyte
- B.
  
  5 kilobytes
- C.
  
  50 kilobytes
- D.
  
  500 kilobytes
Correct Answer
B. 5 kilobytes

Explanation
Since there are 1,000 bytes in a kilobyte, dividing 5,000 bytes by 1,000 gives us 5 kilobytes. Therefore, 5,000 bytes is equivalent to 5 kilobytes.

It is the non-tangible part of an information system that tells the computer how to do its job.
- A.
  
  Hardware
- B.
  
  Software
- C.
  
  Peopleware
- D.
  
  None of the above
Correct Answer
B. Software

Explanation
Software refers to the non-tangible part of an information system that instructs the computer on how to perform its tasks. It includes programs, applications, and data that enable the computer to execute specific functions. Unlike hardware, which encompasses physical components, software is intangible and exists as code or instructions. Peopleware refers to the human elements involved in the system, such as users, designers, and managers. Therefore, the correct answer is software.
