If you want to translate digital codes to audio signals and vice versa, your computer needs a

Sound card
CD-Rom
Scanner

Correct Answer

A. Sound card

Explanation

To translate digital codes to audio signals and vice versa, a computer requires a sound card. A sound card is a hardware component that enables the computer to produce and receive audio signals. It converts digital audio data into analog signals that can be played through speakers or headphones, and also converts analog audio signals from microphones or other audio sources into digital data that can be processed by the computer. Without a sound card, the computer would not be able to generate or interpret audio signals, making it essential for tasks such as playing music, watching videos, or making voice calls.

Which of the following is not an example of a utility program?

Backup software
Operating system
Anti-virus software

Correct Answer

A. Operating system

Explanation

The operating system is not an example of a utility program because it is a fundamental software that manages computer hardware and software resources, provides common services for computer programs, and acts as an interface between the user and the computer. Utility programs, on the other hand, are software tools that perform specific tasks to enhance the system's performance, productivity, and security, such as backup software and anti-virus software.

Which of the following, represents the memory types in decreasing order of their accessing speed?

RAM, ROM, Cache, Magnetic tape, Hard disk
Cache, RAM, ROM, Hard disk, Magnetic tape
Magnetic tape, Hard disk, RAM, ROM, Cache

Correct Answer

A. Cache, RAM, ROM, Hard disk, Magnetic tape

Explanation

The given answer represents the memory types in decreasing order of their accessing speed. Cache memory is the fastest type of memory, followed by RAM (Random Access Memory), ROM (Read-Only Memory), hard disk, and magnetic tape. Cache memory is located close to the CPU, allowing for faster access to frequently used data. RAM is the main memory used by the computer for running programs. ROM contains permanent instructions for the computer. Hard disk is a non-volatile storage device, and magnetic tape is the slowest type of memory used for long-term storage.

It is the central part of an operating system. It manages the tasks of the computer and the hardware – most notably memory and CPU time. What are we talking about?

CPU clock
Operating System
Kernel
ROM

Correct Answer

A. Kernel

Explanation

The correct answer is Kernel. The kernel is the central part of an operating system that manages the tasks of the computer and the hardware, including memory and CPU time. It acts as a bridge between software and hardware, allowing applications to interact with the system's resources. Without the kernel, the operating system would not be able to function properly.

What Did Users Of The First Automatic Teller Machine Access The Machine With?

CD ROM
Magnetic Chip
Radioactive Paper
Gold Plated Transistor chip

Correct Answer

A. Radioactive Paper

Explanation

Users of the first automatic teller machine accessed the machine with radioactive paper. This was a unique and unconventional method of authentication where the user would insert a piece of paper coated with a radioactive substance into the machine. The machine would then detect the radiation emitted by the paper to verify the user's identity. This method was eventually phased out due to safety concerns and replaced with more secure and conventional methods such as magnetic chip cards.
