1. To what temporary area can you store text and other data, later paste them to another location ?

The clipboard

ROM

CD-ROM

The hard disk

Answer: The clipboard

Explanation:

The temporary area where you can store text and other data to later paste them to another location is called the (a) clipboard.


2. A 32-bit-word computer can access __________ byte at a time ?

4

8

16

32

Answer: 32

Explanation:

A 32-bit-word computer can access (b) 4 byte at a time. This is because a byte is made up of 8 bits, so 4 bytes equals 32 bits. A 32-bit computer architecture can process 32 bits of data at a time, which translates to 4 bytes of data. This means that the computer can access, transfer, and process 4 bytes of data in a single clock cycle.


3. Which of the following is a secondary storage device ?

Optical disks

RAM

Microprocessor

All of these

Answer: Optical disks

Explanation:

Optical disks are a type of secondary storage device. Secondary storage devices are non-volatile memory devices used to store data and programs for a long period of time, even when power is turned off. They are also known as external storage devices or auxiliary storage devices. Examples of secondary storage devices include hard disk drives, solid-state drives, USB flash drives, memory cards, optical disks (such as CDs, DVDs, and Blu-ray discs), and magnetic tapes. RAM (Random Access Memory) and microprocessors are not secondary storage devices, but rather primary components of a computer system used for processing and temporarily storing data.


4. Name of round shining portable disk which can store large amount of information and softwares ?

CD-ROM

Floppy disk

Scanner

Monitor

Answer: CD-ROM

Explanation:

CD-ROM (Compact Disc Read-Only Memory) is a round, shining portable disk that can store a large amount of information and software. It is an optical storage medium, which means that it uses laser technology to read and write data. While CD-ROMs have largely been replaced by other storage media such as USB drives and cloud storage, they are still used for some applications such as software installation and distribution.


5. The result of computer processing of your input is called ?

output

data

multi tasking

tracking

Answer: output

Explanation:

Output. The result of computer processing of your input is called output. This refers to the information or data that is produced by a computer program or process as a result of input data being processed. This output can be in various forms, such as text, images, audio, video, or any other type of digital data. It can be displayed on a screen, printed on paper, or stored in a file for future use.


6. When you save to _________, your data will remain intact even when the computer is turned off ?

RAM

motherboard

secondary storage device

primary storage device

Answer: secondary storage device

Explanation:

When you save to a secondary storage device such as a hard drive, solid-state drive, or USB drive, your data will remain intact even when the computer is turned off. This is because secondary storage devices are non-volatile, meaning they retain their data even when power is turned off. In contrast, primary storage devices such as RAM are volatile and only retain their data as long as power is supplied to them.


7. Approximately how many bytes make one Megabyte ?

One Thousand

Ten Thousand

One Hundred

One Million

Answer: One Million

Explanation:

One Megabyte is approximately equal to one million bytes. In computing, the prefix "mega-" usually denotes a factor of 10^6 (1,000,000), so a Megabyte is equal to 1,000,000 bytes. However, in some contexts, the prefix "mega-" can denote a factor of 2^20 (1,048,576), which is known as a Mebibyte. This distinction is important in certain technical contexts, but for most everyday purposes, the terms Megabyte and Mebibyte can be used interchangeably.


8. What is the major disadvantage of RAM ?

Its access speed is too slow

Its matrix size is too big

It is volatile

High power consumption

Answer: It is volatile

Explanation:

The major disadvantage of RAM (Random Access Memory) is that it is volatile, meaning that its contents are lost when power is turned off. This means that any data stored in RAM will be lost if the computer is shut down or crashes unexpectedly. To prevent the loss of data, it is important to save your work frequently and back up important data to non-volatile storage devices such as hard drives or cloud storage. However, the advantages of RAM (such as its high speed and ability to access data quickly) generally outweigh this disadvantage, making it a crucial component in modern computer systems.


9. What disk is used to cold-boot a PC ?

Setup disk

System disk

Diagnostic disk

Program disk

Answer: System disk

Explanation:

A system disk is typically used to cold-boot a PC (i.e., to start up the computer when it is turned off). A system disk contains the essential files needed to start up the operating system and boot the computer. It is also used to repair or restore the operating system in the event of a system failure or error. System disks can be created using special software tools or can be purchased from the operating system vendor.


10. Which of the following devices has a limitation that we can only read it but cannot erase or modify it ?

Tape Drive

Hard Disk

Compact Disk

Floppy Disk

Answer: Tape Drive

Explanation:

Compact disks (CDs) are a type of optical storage device that can store large amounts of data, including music, videos, and software. Once data is written to a CD, it cannot be erased or modified, making it a read-only medium. This makes CDs a popular format for distributing software and other content that users are not supposed to modify. CDs can be read by CD-ROM drives, which use a laser to read the data stored on the disk's surface.
