- True
- False

About This Quiz

This quiz titled 'Computer Memory' explores fundamental concepts of data storage in computing, such as the difference between memory and storage, units of data measurement, and historical storage devices. It assesses understanding of memory hierarchy and data unit sizes, relevant for learners in computer science.

2.

What dose MB stand for?
- Mario brothers
- Make or break
- Mega byte
- Masala bugia
Correct Answer

A. Mega byte

Explanation

MB stands for mega byte, which is a unit of digital information storage. It is commonly used to measure the size of files, data, or computer memory.

3.

What comes after a terabyte?
- Gigabyte
- Kilobyte
- Megabyte
- Petabyte
- Allof the above
Correct Answer

A. Petabyte

Explanation

A terabyte is a unit of digital information that is equivalent to 1,024 gigabytes. The next unit of measurement after a terabyte is a petabyte, which is equal to 1,024 terabytes. Therefore, the correct answer is petabyte.

4.

How much Can 1 byte hold?
- 1 letter
- 1 word
- 1page
- Upto 3 words
- None of the above
Correct Answer

A. 1 letter

Explanation

A byte is a unit of digital information that typically consists of 8 bits. Each bit can represent a binary value of 0 or 1. Since a letter can be represented by a single character, which requires 8 bits or 1 byte of storage, the correct answer is "1 letter".

What is a floppy disk?
- A a nentendo ds card
- A magic disc made of rubber
- A old form of memory disk
- A giant record player
- I dont know
Correct Answer

A. A old form of memory disk

Explanation

The correct answer is "a old form of memory disk." A floppy disk refers to a type of portable storage device that was commonly used in the past to store and transfer data. It is a thin, flexible disk made of magnetic material encased in a square or rectangular plastic shell. Floppy disks were popular in the 1970s and 1980s but have become obsolete with the advancement of technology and the introduction of more efficient and compact storage devices such as USB drives and cloud storage.

6.

A byte is 1/3 of a bit
- True
- False
Correct Answer

A. False

Explanation

The statement that a byte is 1/3 of a bit is false. In computer science, a bit is the smallest unit of information and can have two possible values, 0 or 1. On the other hand, a byte is a unit of digital information that consists of 8 bits. Therefore, a byte is much larger than a bit and cannot be 1/3 of it.

7.

ROM is NOT read only memory?
- True
- False
Correct Answer

A. False

Explanation

The statement "ROM is NOT read only memory" is false. ROM stands for Read-Only Memory, which is a type of computer memory that can only be read and not written to. Therefore, the correct answer is false.

What is the diffrense between storage and memory?
- Memory is permanant while storage isnt
- Both are temporary and erasible
- Storage is premanant while memory is not
- None of the above
- I dont know
Correct Answer

A. Storage is premanant while memory is not

Explanation

The given answer states that storage is permanent while memory is not. This explanation correctly differentiates between storage and memory. Storage refers to long-term data retention, such as hard drives or solid-state drives, where data can be stored even when the power is off. Memory, on the other hand, refers to temporary data storage that is erased when the power is turned off, such as RAM (Random Access Memory). Therefore, the statement accurately describes the difference between storage and memory.

What is the diffrence between cd roms and dvd roms
- Cd roms are square
- Dvd roms are triangular
- Dvd roms have larger memorys
- Allof the above
Correct Answer

A. Dvd roms have larger memorys
10.

Whate is a nibble?
- A small byte of food
- A group of 2 bytes
- A group of 4 bits
- A hand held deyice for plaving games
- None of the above
Correct Answer

A. A group of 4 bits

Explanation

A nibble is a term used in computing to refer to a group of 4 bits. In binary code, a bit can have a value of either 0 or 1. A nibble, therefore, can represent 16 different values ranging from 0000 to 1111. It is half of a byte, which consists of 8 bits. Nibbles are often used in hexadecimal notation, where each nibble corresponds to a single digit (0-9, A-F).

RAM (Random Access Memory) is a type of computer memory that temporarily stores data for active programs and processes, and its contents are erased when the computer is powered off.
- True
- False
Correct Answer

A. True

Explanation

RAM is a form of volatile memory used to store data that the CPU needs quick access to while running programs. It allows for faster performance because data can be read and written quickly. However, RAM is temporary, meaning that once the computer is turned off, all data stored in RAM is lost, unlike storage devices like hard drives or SSDs that retain data even when powered down.
