Which is not impact printer?
- A.
Laser printer
- B.
Dot-matrix printer
- C.
Daisy wheel
- D.
Line printer
Correct Answer
A. Laser printerExplanation
A laser printer is not an impact printer because it does not physically strike the paper to create an image. Instead, it uses a laser beam to transfer toner onto the paper, creating high-quality prints. In contrast, dot-matrix printers, daisy wheel printers, and line printers all use physical impact to create characters on the paper. Dot-matrix printers use a matrix of pins to strike an ink ribbon, while daisy wheel printers use a rotating wheel with characters on it. Line printers use a line of print hammers to strike the paper.Rate this question:

Which one is a sequential (series) access device?
- A.
Floppy disk
- B.
Magnetic tape
- C.
Compact disk
- D.
None of above
Correct Answer
B. Magnetic tapeExplanation
A magnetic tape is a sequential (series) access device because it stores data in a linear format that can only be accessed sequentially. To retrieve data from a magnetic tape, the tape must be wound or rewound to the specific location where the data is stored. This makes it suitable for applications that require large amounts of data to be stored and accessed sequentially, such as backup systems or archival storage. Floppy disks and compact disks, on the other hand, are random access devices, meaning that data can be accessed directly without the need to sequentially move through the storage medium.Rate this question:

Which one is primary storage?
- A.
PROM
- B.
Hard disk
- C.
CPU
- D.
Zip disk
Correct Answer
A. PROMExplanation
PROM (Programmable Read-Only Memory) is the correct answer because it is a type of non-volatile memory that is used for permanent data storage. It is considered primary storage because it is directly accessible by the CPU and is used to store important data and instructions that are frequently accessed by the computer. Hard disk, CPU, and Zip disk are not considered primary storage as they serve different functions in the computer system.Rate this question:

Which memory loses data when power is off?
- A.
RAM
- B.
PROM
- C.
EAPROM
- D.
ROM
Correct Answer
A. RAMExplanation
RAM (Random Access Memory) loses data when power is off. This is because RAM is a volatile memory type that requires a constant power supply to retain data. When the power is turned off, the stored data in RAM is immediately lost. Unlike other memory types like PROM, EAPROM, and ROM, which are non-volatile and can retain data even when power is off, RAM is designed for temporary storage and quick access of data while the system is operational.Rate this question:

Which program translates one line at a time?
- A.
Interpreter
- B.
Translator
- C.
Compiler
- D.
Assembler
Correct Answer
A. InterpreterExplanation
An interpreter is a program that translates and executes one line of code at a time. It reads each line, translates it into machine code or bytecode, and immediately executes it. This allows for a line-by-line execution and immediate feedback on any errors or issues encountered. In contrast, a compiler translates the entire program into machine code before execution, and an assembler translates assembly language into machine code. A translator is a more general term that can refer to any program that converts code from one language to another.Rate this question:
