What is the smallest unit of memory?
BitsBits are the basic building blocks of not only data storage, but all computers.
Computers work in binary digits, combining 0’s and 1’s in countless patterns.
These binary digits are known as bits, and are the smallest possible unit for data storage.
When 8 bits are combined, you get a byte..
What are the byte sizes?
How much is 1 byte, kilobyte, megabyte, gigabyte, etc.?Nibble. A nibble is 4 bits.Byte. Today, a byte is 8 bits.Kilobyte (KB) A kilobyte is 1,024 bytes.Megabyte (MB) A megabyte is 1,048,576 bytes or 1,024 kilobytes.Gigabyte (GB) A gigabyte is 1,073,741,824 (230) bytes. … Terabyte (TB) … Petabyte (PB) … Exabyte (EB)More items…•
What are two bytes called?
HalfwordHalfword (two bytes). Word (four bytes). Giant words (eight bytes).
Is a word 2 bytes?
Data structures containing such different sized words refer to them as WORD (16 bits/2 bytes), DWORD (32 bits/4 bytes) and QWORD (64 bits/8 bytes) respectively.
Why is a bit called a bit?
The bit is a basic unit of information in computing and digital communications. The name is a portmanteau of binary digit.
What’s higher than a zettabyte?

How many numbers can you represent with 2 bytes?
65536If two bytes are used to represent numbers, that means that we define some function mapping the 65536 possible distinct values that those two bytes can take, to the numbers that these values represent.
What is a nibble in binary?
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.
What is bigger MB or GB?
1 Megabyte is considered to be equal to 0.001 gigabytes in decimal and 0.0009765625 gigabytes in binary system. 1 Gigabyte is considered to be equal to 1000 megabytes in decimal and 1024 megabytes in binary system. As you can see, 1 Gigabyte is 1000 times bigger than a Megabyte. So, a GB is bigger than a MB.
Is a word 4 bytes?
A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits).
How many bytes is a sentence?
12 bytes including spaces and the ‘? ‘. There are 7, 8 or 9 bits in a byte depending on whether you use the ACII or EBCDIC coding, with or without a parity bit. This sentence can be represented as an ASCII string.
How much is a bit?
A bit is 1/8 of a dollar or 12.5 cents. You can figure that out from context too. 2 bits, 4 bits, 6 bits, a dollar. In sequence that means they are describing 25 cents, 50 cents, 75 cents, a dollar.
What are all the bytes called?

Why do bytes have 8 bits?
The byte was originally the smallest number of bits that could hold a single character (I assume standard ASCII). We still use ASCII standard, so 8 bits per character is still relevant. This sentence, for instance, is 41 bytes. That’s easily countable and practical for our purposes.
What is a group of 16 bits called?
hextetIn computing, a hextet is a sixteen-bit aggregation, or four nibbles. As a nibble typically is notated in hexadecimal format, a hextet consists of 4 hexadecimal digits. A hextet is the unofficial name for each of the 8 blocks in an IPv6 address.
What are 4 bits called?
nibbleIn computing, a nibble (occasionally nybble or nyble to match the spelling of byte) is a four-bit aggregation, or half an octet. It is also known as half-byte or tetrade. In a networking or telecommunication context, the nibble is often called a semi-octet, quadbit, or quartet.
What is a double word?
Browse Encyclopedia Twice the length of a single computer word. A double word is typically 32 bits long. See word. THIS DEFINITION IS FOR PERSONAL USE ONLY.
Why is a kilobyte 1024 bytes?
Answer: Many people think that there are 1000 bytes in a kilobyte. … But there are really 1024 bytes in a kilobyte. The reason for this is because computers are based on the binary system. That means hard drives and memory are measured in powers of 2.
