What does 8 bit 16 bit and 32-bit mean?

1 byte is 8 bits. We get our ASCII charachter set from the 8 bit ASCII system because you have 256 combinations (0-255). 8-bit color deals with 256 colors. 16 bit is 65,536 combinations (or in the case of color, 65,536 colors). 32 bit is MILLIONS of combinations/colors.

How many bits wide is the address of a 32-bit computer?

4 octets
In computer architecture, 32-bit integers, memory addresses, or other data units are those that are 32 bits (4 octets) wide.

How many bits can a register of a 32-bit computer system hold?

And to allocate/define an address computer would need a bit. So a computer of 32 bits can provide upto 4.294 x 10^9 addresses. Since each address is a bit, maximum memory would scale upto 4.294 x 10^9 bits, which is roughly 4 GB. Hence a 32 bit computer can support upto 4GB of RAM.

What is a 32-bit word?

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).

What does 32bit mean?

1. 32-bit is a type of CPU architecture that is capable of transferring 32 bits of data per clock cycle. In more technical terms, this means processors can work with 32-bit binary numbers (decimal number up to 4,294,967,295). Anything larger and the computer would need to break the data into smaller pieces.

How many 32-bit addresses are there in a 32 bit instruction?

• If memory addresses are 32 bits, the instruction takes three 32 -bit addresses in addition to the opcode. Two general methods are used to reduce the size of the specification

What is the size of 32 bit instruction in assembly language?

As instruction size given is 32 bits, remaining bit left for operand = 32-16 = 16 bits. Que-3. A machine has a 32-bit architecture, with 1-word long instructions. It has 64 registers, each of which is 32 bits long. It needs to support 45 instructions, which have an immediate operand in addition to two register operands.

How many bits are there in an instruction?

Instructions would normally be 24 bits long, plus 24 bits for each memory address to be specified in the instruction. The instruction formats of some of these computers are shown in the diagram below:

How many opcodes are there in a 4-bit opcode?

• This might be reasonable on a machine that has 16 registers on which all arithmetic operations take place. • One design would be a 4-bit opcode and three addresses in each instruction, giving 16 three – address instructions.
