1. Which part is the “brain” of the Computer ?

CPU

Monitor

Ram

ROM

Answer: CPU

Explanation:

CPU (Central Processing Unit) is often referred to as the "brain" of the computer. It is responsible for executing instructions and performing calculations. The CPU is a chip that is located on the motherboard and communicates with other components of the computer, such as memory and storage devices, to perform tasks.


2. When you make graph and picture in document, then your computer holds the data in __________ ?

Restore file

Backup drive

Clipboard

Memory

Answer: Memory

Explanation:

When you make a graph and picture in a document, the computer holds the data in "memory" (RAM - Random Access Memory) until it is saved to a storage device, such as a hard drive or flash drive. Therefore, the answer is (d) Memory.


3. To put information in a file on a magnetic disk, or in a computer’s memory, so it can be used later __________ ?

store

ship

shift

centre

Answer: store

Explanation:

The correct answer is (a) store. To store information in a file on a magnetic disk, or in a computer's memory, means to save it there so that it can be used later. Storing information is a fundamental operation in computer science and is essential for preserving data and making it available for processing and analysis. The other options listed are not related to this process: "ship" means to transport something to another location, "shift" means to move something from one place to another, and "centre" means to focus on the central point or location.


4. A hard disk drive is considered as a __________ storage ?

flash

non volatile

temporary

non-permanent

Answer: non volatile

Explanation:

A hard disk drive is considered as a non-volatile storage because it retains its data even when power is turned off, unlike temporary or volatile storage such as RAM which loses its data when power is turned off.


5. A tape drive offers __________ access to data ?

timely

sporadic

random

sequential

Answer: sequential

Explanation:

Sequential access. A tape drive offers sequential access to data, which means that data is accessed in a linear manner, from the beginning of the tape to the end. In order to access a particular piece of data, the tape drive must read through all of the preceding data. This can be slower than random access, which allows data to be accessed in any order. However, tape drives are still used for certain applications, such as data backup and archiving, where large amounts of data need to be stored in a cost-effective manner.


6. Which of the following is not true about RAM ?

RAM is a temporary storage area

RAM is the same as hard disk storage

RAM is volatile

Information stored in RAM is gone when you turn the computer off

Answer: RAM is the same as hard disk storage

Explanation:

RAM is the same as hard disk storage is not true about RAM. RAM and hard disk storage are two different types of memory in a computer. RAM is a volatile, temporary storage area that the computer uses to store data and programs that are currently in use, while hard disk storage is a non-volatile, permanent storage area used to store data and programs that are not currently in use.


7. The following computer’s memory is characterised by low cost per bit stored ?

Primary

Secondary

Hard Disk

All of these

Answer: Secondary

Explanation:

Secondary memory is characterized by low cost per bit stored, as it is used for long-term storage of data and information. Secondary memory includes storage devices such as hard disks, optical disks, USB drives, and memory cards. Primary memory, on the other hand, is characterized by high speed and is used for short-term storage of data and instructions that are currently being processed by the CPU. Examples of primary memory include RAM and cache memory. Therefore, option (b) Secondary is the correct answer.


8. Which type of memory is closely related to processor ?

Main Memory

Secondary Memory

Disk Memory

Tape Memory

Answer: Main Memory

Explanation:

Main Memory is closely related to the processor.


9. Memory, also called random access memory, or RAM, __________ ?

contains the electronic circuits that cause processing to occur.

makes the information resulting from processing available for use

allots data, programs, commands, and user responses to be entered into a computer

consists of electronic components that store data

Answer: consists of electronic components that store data

Explanation:

Memory, also called random access memory, or RAM, "consists of electronic components that store data". Therefore, the answer is (d) consists of electronic components that store data.


10. A removable magnetic disc that holds information ?

floppy disk

hard drive

monitor

portable

Answer: floppy disk

Explanation:

The correct answer is (a) floppy disk, which is a removable magnetic disc that is used to store information. Floppy disks were commonly used in the past for backing up and transferring data between computers, but they have largely been replaced by more advanced storage technologies such as USB flash drives and cloud storage. Floppy disks were available in different sizes, with the most common being the 3.5-inch disk that could hold up to 1.44 megabytes of data.
