The daily processing of corrections to customer accounts best exemplifies the processing mode of:
- A.
1) Batch processing
- B.
2) Real-time processing
- C.
3) Interactive processing
- D.
4) Multi processing
- E.
5) All of the above.
Correct Answer
A. 1) Batch processingExplanation
The daily processing of corrections to customer accounts is best exemplified by batch processing. Batch processing involves collecting and processing a large amount of data at one time. In this case, the corrections to customer accounts are likely gathered throughout the day and processed in a batch at the end of the day or during a specific time period. This allows for efficient and consistent processing of a large volume of corrections.Rate this question:

Which is a unit of measurement used with computer systems?
- A.
1) Byte
- B.
2) Kilobyte
- C.
3) Megabyte
- D.
4) Gigabyte
- E.
5) All of the above
Correct Answer
E. 5) All of the aboveExplanation
The answer is "All of the above" because all the options listed (Byte, Kilobyte, Megabyte, and Gigabyte) are units of measurement used with computer systems to measure storage capacity. Each unit represents a different magnitude of data storage, with Byte being the smallest unit and Gigabyte being the largest. Therefore, all of these units are commonly used in computer systems.Rate this question:

A character is represented in EBCDIC by
- A.
1) one bit
- B.
2) four bits
- C.
3) eight bits
- D.
4) sixteen bits
- E.
5) None of the above
Correct Answer
C. 3) eight bitsExplanation
In EBCDIC, a character is represented by eight bits. EBCDIC (Extended Binary Coded Decimal Interchange Code) is an 8-bit character encoding used mainly on IBM mainframe and IBM midrange computer systems. It was widely used in the past, but has been largely replaced by ASCII (American Standard Code for Information Interchange) in modern computing systems.Rate this question:

Which is a secondary memory device?
- A.
1) CPU
- B.
2) ALU
- C.
3) Floppy disk
- D.
4) Mouse
- E.
5) None of the above
Correct Answer
C. 3) Floppy diskExplanation
A floppy disk is a secondary memory device because it is used for long-term storage of data. It is a portable storage medium that can be read from and written to, making it ideal for transferring and storing files. Unlike primary memory devices like the CPU and ALU, which are responsible for processing and executing instructions, a floppy disk is used solely for storage purposes. Similarly, a mouse is an input device and not a memory device. Therefore, the correct answer is 3) Floppy disk.Rate this question:

Which is the computer memory that does not forget?
- A.
1) ROM
- B.
2) RAM
- C.
3) PROM
- D.
4) All of the above
- E.
5) None of the above
Correct Answer
A. 1) ROMExplanation
ROM stands for Read-Only Memory, which is a type of computer memory that retains its data even when the power is turned off. It is non-volatile memory, meaning it does not forget the stored data. Unlike RAM (Random Access Memory), which is volatile and loses data when power is lost, ROM is used to store permanent instructions or data that should not be changed. PROM (Programmable Read-Only Memory) is a type of ROM that can be programmed once, while RAM is temporary memory used for data storage during the operation of a computer. Therefore, the correct answer is ROM.Rate this question:

The most common binary code in use today is the 8 bit ASCII code. What do the letters ASCII stand for?
- A.
1) American Standard Code for International Interchange
- B.
2) American Standard Code for Information Interchange
- C.
3) American Standard Code for Intelligence interchange
- D.
4) American Scientific Code for Information Interchange
- E.
5) None of the above

A computer derives its basic strength from
- A.
1) Speed
- B.
2) Accuracy
- C.
3) Memory
- D.
4) all of the above
- E.
5) None of the above
Correct Answer
D. 4) all of the aboveExplanation
A computer derives its basic strength from its speed, accuracy, and memory. Speed refers to the ability of a computer to process instructions and perform tasks quickly. Accuracy refers to the computer's ability to perform tasks without errors or mistakes. Memory refers to the computer's ability to store and retrieve data. All of these factors contribute to the overall strength and effectiveness of a computer system.Rate this question:

A collection of eight bits is called
- A.
1) Byte
- B.
2) Word
- C.
3) Record
- D.
4) file
- E.
5) None of the above
Correct Answer
A. 1) ByteExplanation
A collection of eight bits is called a byte. A byte is the basic unit of storage in computer systems and is commonly used to represent a single character of text or a small amount of data. It is composed of eight bits, each of which can be either a 0 or a 1. Bytes are widely used in computer programming and data storage, and multiple bytes are often used to represent larger units of information.Rate this question:

A BIT represents a
- A.
1) Decimal digit
- B.
2) Octal digit
- C.
3) Binary digit
- D.
4) Hexadecimal digit
- E.
5) none of these
Correct Answer
C. 3) Binary digitExplanation
A BIT represents a binary digit. In computing, a bit is the basic unit of information and can have two possible values, 0 or 1. It is used to represent the smallest unit of data in a computer system and is the foundation of all digital data processing. The other options, such as decimal digit, octal digit, and hexadecimal digit, are not correct because they do not specifically represent the binary system.Rate this question:

Which can read data and convert them to a form that a computer can use?
- A.
1) Logic
- B.
2) Storage
- C.
3) Control
- D.
4) Input device
- E.
5) Output device
Correct Answer
D. 4) Input deviceExplanation
Input devices are hardware devices that allow users to input data into a computer. These devices can read data from external sources and convert them into a form that a computer can understand and process. Examples of input devices include keyboards, mice, scanners, and microphones. These devices play a crucial role in enabling users to interact with a computer and provide the necessary input for various tasks and operations. Therefore, option 4) Input device is the correct answer as it accurately describes the function of devices that can read data and convert them into a usable form for a computer.Rate this question:
