Memory | MCQs

Explanation

RAM is a volatile memory.

RAM: Random Access Memory

ROM is a non-volatile memory.

ROM: Read Only Memory

Explanation

Feature Virtual Memory

Location: On the hard drive or SSD

Speed: Slower (due to disk I/O operations)

Capacity: Larger, limited by disk space

Cost: Lower (cost of additional disk storage)

Explanation

Petabyte (1,024 Terabytes, or 1,048,576 Gigabytes)

Explanation

RAM is volatile and primary memory.

ROM is non-volatile and permanent storage.

Explanation

Memory retrieval is the process of remembering information stored in long-term memory.

Explanation

The main memory of a computer is also known by several names, including:

• Primary storage
• Internal memory
• Primary memory
• Main storage
• Random Access Memory (RAM)

All these terms refer to the computer's volatile memory, which temporarily stores data and programs that are currently being used or processed by the CPU (Central Processing Unit).

RAM is a primary memory.

ROM is a primary memory.

RAM stands for: Random Access Memory

ROM stands for: Read Only Memory

Explanation

A bus is a high-speed internal connection that sends data and control signals between the processor and other components.

The amount of data a data bus can transfer is known as bandwidth. 

1. Data bus: A bidirectional communication path that transfers data between the CPU, memory, and input/output devices.
2. Address bus: Transmits the physical location (address) of data to be accessed or written by the CPU.
3. Control bus: Transfers control signals for coordinating the overall system's operation.

Explanation

One Gigabyte (GB) is equal to 2^30 bytes, which is 1,073,741,824 bytes.

The size of information in the computer is measured in Kilobytes (KB), Megabytes (MB), Gigabytes (GB), and Terabytes (TB).

1 Kilobyte (KB) = 1024 bytes

One Megabyte (MB) = 1024 Kilobytes (KB

One Gigabyte (GB) =  1024 Megabytes MB

One Terabyte (TB)= 1024 gigabytes (GB).

Explanation

In both C and C++ programming languages, the symbol used to access the value stored at a memory address (dereferencing a pointer) is the asterisk (*).

* and & are the operators used in pointers.

* gives us the value stored at a particular address

whereas “ & “ gives us the address of the variable

Explanation

Primary storage, also known as main storage or memory.

It is the area in a computer in which data is stored for quick access by the computer's processor.

The terms random access memory (RAM) and memory are often as synonyms for primary or main storage.
