What is the size of an integer on a 16 bit system?

2 bytes
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.

How many numbers can you represent with 2 bytes 16 bits )?

65,536 different
Two bytes is 16 bits, so two bytes can represent 216 = 65,536 different values. We use about half of these to represent negative numbers, about half for postive numbers, and one to represent zero. Four bytes is 32 bits, so four bytes can represent 232 = 4,294,967,296 different values.

How many bytes are in a 16 bit block of data?

Using 16 bits, you can write 65536 addresses (from 0 to 65535, that’s 65536 different addresses), and address 65536 bytes. 65536 bytes is 64kB.

What is the size of int variable in bit?

The most commonly used integer type is int . It is a signed 32-bit (4 bytes) type that has a range from -2,147,483,648 to 2,147,483,647 .

Why is int 2 bytes?

So, size of int data type is 2 bytes means that the compiler uses two bytes to store a int value. The value can be anything; it can be zero or one hundred but two bytes would always be used to keep it in memory. Now each bit in binary can either be 0 or be 1. That means 1 bit can hold only two numbers: 0 and 1.

How do you represent 2 bytes?

Two bytes is usually called a word, or short word (though word-length depends on the application). A two-byte word is also the size that is usually used to represent integers in programming languages. A long word is usually twice as long as a word. A less common unit is the nibble which is 4 bits, or half of a byte.

What is meant by 16 bit processor?

The 16 bit Microprocessor means that it has 16 address lines. A 16 bit microprocessor is having 16bit register set. It have 16 address and data lines to transfer address and data both. Hence it is 16 address lines. The maximum addresses are 2^16 means 65536.

What is the size of int in bytes?

4 bytes
