Computer cache definition Cache is the temporary memory officially termed “CPU cache memory.” This chip-based feature of your computer lets you access some information more quickly than if you access it from your computer’s main hard drive. Jan 26, 2021
What is ROM used for?
ROM provides the necessary instructions for communication between various hardware components. As mentioned before, it is essential for the storage and operation of the BIOS, but it can also be used for basic data management, to hold software for basic processes of utilities and to read and write to peripheral devices.
What is RAM used for?
RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor.
What are the 5 stages of memory?

With the sensory information passed to the brain, the volume and complexity is too great to process. … Consolidation. … Storage. … Retrieval. Jan 29, 2021
Is MB or GB more?
If you literally just want the answer to the question you just asked, there are 1024MB (megabytes) in one GB (gigabyte). If you want to know more there are 1024 gigabytes in a terabyte (TB) and 1024 terabytes in one petabyte (PB). Feb 10, 2021
How much is a GB?
1 billion bytes What is a gigabyte (GB)? A gigabyte (GB) — pronounced with two hard Gs — is a unit of data storage capacity that is roughly equivalent to 1 billion bytes. In decimal notation (base 10), a gigabyte is exactly 1 billion bytes. In binary notation (base 2), a gigabyte is equal to 230 bytes, or 1,073,741,824 bytes.
What’s smaller than a kilobyte?
The kilobyte is the smallest unit of memory measurement but greater than a byte. … Types of various Units of Memory- Name Equal To Size(In Bytes) Kilobyte 1024 Bytes 1024 Megabyte 1, 024 Kilobytes 1, 048, 576 Gigabyte 1, 024 Megabytes 1, 073, 741, 824 Terrabyte 1, 024 Gigabytes 1, 099, 511, 627, 776 7 more rows • Apr 15, 2021
What is the biggest byte?
yottabyte A yottabyte is the largest unit approved as a standard size by the International System of Units (SI). The yottabyte is about 1 septillion bytes — or, as an integer, 1,000,000,000,000,000,000,000,000 bytes.
What is bigger than 1tb?
Therefore, after terabyte comes petabyte. Next is exabyte, then zettabyte and yottabyte. However, binary does not operate on the same scale as SI.
How do you calculate bytes?
The calculations is based on: 1 byte = 8 bits. 1 kilobyte (K / Kb) = 2^10 bytes = 1,024 bytes. 1 megabyte (M / MB) = 2^20 bytes = 1,048,576 bytes. 1 gigabyte (G / GB) = 2^30 bytes = 1,073,741,824 bytes.
How many bytes is a Boolean?
2-byte Boolean variables are stored as 16-bit (2-byte) numbers, but they can only be True or False. Sept 13, 2021
What is the size of INT?
The size of a signed int or unsigned int item is the standard size of an integer on a particular machine. For example, in 16-bit operating systems, the int type is usually 16 bits, or 2 bytes. In 32-bit operating systems, the int type is usually 32 bits, or 4 bytes. Aug 3, 2021
What is the smallest unit of data?
A byte is the smallest unit of memory used in today’s computing. Bytes consist of eight bits, and a byte is used to encode a single number, letter, or symbol.
What is the smallest unit of information?
bit The smallest unit of information, a computer can understand and process is known as a bit.
Why 32-bit is 4 bytes?
A 32 bit address contains always 32 bits; if you count 1 byte as 8 bits then that will correspond to 4 bytes.
