Why sizeof int is 4?

int means a variable whose datatype is integer. sizeof(int) returns the number of bytes used to store an integer. ... On a 32-bit Machine, sizeof(int*) will return a value 4 because the address value of memory location on a 32-bit machine is 4-byte integers.

Why is an int 4 bytes?

So the reason why you are seeing an int as 4 bytes (32 bits), is because the code is compiled to be executed efficiently by a 32-bit CPU. If the same code were compiled for a 16-bit CPU the int may be 16 bits, and on a 64-bit CPU it may be 64 bits.

How many bytes is 4 numbers?

Integers are commonly stored using a word of memory, which is 4 bytes or 32 bits, so integers from 0 up to 4,(232 - 1) can be stored.

Why integer is 4 bytes in Java?

Originally Answered: What it means "an integer occupies 4 bytes:? In simple terms,it means that when you define an integer type variable in any programming language,a memory of 4 bytes will be allocated to store its value(although the size depends on the language you are using).

How big is a 4 byte integer?

What are 16 bits called?

There's no universal name for 16-bit or 32-bit units of measurement. The term 'word' is used to describe the number of bits processed at a time by a program or operating system. So, in a 16-bit CPU, the word length is 16 bits. ... I used to ear them referred as byte, word and long word.

What is a group of 16 bits called?

Bytes are a pretty common buzzword when working in binary. ... It could be 16-bits, 32, 64, or even more. ocabanga44 and 28 more users found this answer helpful.

Which is an example of a byte?

For numeric data, one byte holds one decimal digit (0-9), two "packed decimal" digits (00-99) or a binary number from . ... An example of a byte is combination of bits used in computer coding to represent a letter in an alphabet.

What is the full meaning of byte?

Byte, the basic unit of information in computer storage and processing. A byte consists of 8 adjacent binary digits (bits), each of which consists of a 0 or 1. ... The string of bits making up a byte is processed as a unit by a computer; bytes are the smallest operable units of storage in computer technology.

What is 1 byte of data also called?

What is 1 byte of data also called? character. You just studied 41 terms! 1/41.

Why is it called a byte?

The term byte was coined by Werner Buchholz in June 1956, during the early design phase for the IBM Stretch computer, which had addressing to the bit and variable field length (VFL) instructions with a byte size encoded in the instruction. It is a deliberate respelling of bite to avoid accidental mutation to bit.
