What is smaller than a nibble?
There are bits and nibbles.
The bit is the smallest, then the nibble, which is half a byte.
A half a byte is a “nibble”..
Which is bigger nibble or byte?
Nibble – 4 bits (half a byte) Byte – 8 bits. Kilobyte (KB) – 1000 bytes.

What is the difference between nibble and byte?
Each 1 or 0 in a binary number is called a bit. From there, a group of 4 bits is called a nibble, and 8-bits makes a byte. Bytes are a pretty common buzzword when working in binary. Processors are all built to work with a set length of bits, which is usually this length is a multiple of a byte: 8, 16, 32, 64, etc.
What is the small unit of storage?
bytesByte is the basic unit of information in digital technology. It is also the most common unit of storage and one of the smallest units of memory in computer. 1 byte consists of 8 bits and it also means 1 bit is 1/8 bytes.
Which is the fastest memory?
Fastest memory is cache memory.Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster.More items…
Which is the fastest memory RAM or cache?
Cache memory increase the accessing speed of CPU. RAM is faster than a hard disk, floppy disk, compact disk, or just any form of secondary storage media. 7. CPU reads Cache Memory data before reading RAM.
What is unit of memory?
Memory unit is the amount of data that can be stored in the storage unit. This storage capacity is expressed in terms of Bytes.
What are 2 bytes called?
HalfwordHalfword (two bytes). Word (four bytes). Giant words (eight bytes).
Why is 4 bits called a nibble?
The term ‘nibble’ originates from its representing ‘half a byte’, with ‘byte’ a homophone of the English word ‘bite’.
Which is the smallest and largest unit of memory you know?
When 8 bits are combined, you get a byte. Bytes are used to store a single character; whether’s it a letter, number, or punctuation….Data Storage Units Chart: From Smallest to Largest.UnitShortenedCapacityKilobyteKB1024 bytesMegabyteMB1024 kilobytesGigabyteGB1024 megabytesTerabyteTB1024 gigabytes6 more rows•Jan 24, 2020
Whats bigger MB or GB or KB?
KB, MB, GB – A kilobyte (KB) is 1,024 bytes. A megabyte (MB) is 1,024 kilobytes. A gigabyte (GB) is 1,024 megabytes. A terabyte (TB) is 1,024 gigabytes.
Why cache memory is faster?
Since the cache memory is faster than RAM, and because it is located closer to the CPU, it can get and start processing the instructions and data much more quickly. The same procedure is carried out when data or instructions need to be written back to memory.
Why are registers faster than memory?
The compiler decides what variables should be in registers and when. Registers are essentially internal CPU memory. So accesses to registers are easier and quicker than any other kind of memory accesses.
