What is the difference between 8 bit and 16 bit ina computer?

Answer 1

the number of bits describing the architecture of a CPU system define its maximum "word size", or how many bits it can process at one time. In an 8-bit system, a standard integer can hold a value of up to +127, and an unsigned integer can hold a value up to +255. In a 16-bit system, unsigned integers can hold values up to 2^16 - 1, or 65,535.

When speaking of 8-bit and 16-bit color, for 8-bit color you can either mean the palette size (256 colors, each of which can be assigned any color) where only 256 unique colors can be used at a time. The other meaning of 8-bit color is a different 256-color system (called 8-bit truecolor) where you define the color by attributing 3 bits to red, 3 to green, and 2 to blue. This system is less effective than the 8-bit palette system.

16-bit color (also called high-color or 16-bit truecolor) allows a total of 65,536 unique colors to be displayed, anywhere on screen at any time, by assigning 5 bits to the red and blue channels, and 6 bits to the green channel (our eyes are more sensitive to green).

Answer 2

The internal parts like registers and ALU use data in 8-bits in a 8 nit processor and so in a 16 bit and 32 bit processor the use 32 bit data.....the BUS which carries data from one part of a proceesor to another has 8-lines in a 8 bit processor,16 lines in a 16 bit and 32lines ina 32 bit one.....because all these bits have to be transmitted simultaneously.

Answer 3

The length of commands a microprocessor can address per clock cycle is in part measured by the bit-rate and the operations per cycle. In your case, the bit rate, the literal string length of commands is addressed:

Falling back on my Bus width answer, the elemental difference between a 16-bit and 32-bit processor is pretty easy when drawn out for you. I'll use the band name "ABBA" for an example.

A 16-bit processor would run the string "ABBA" like this:

Receive command

Instruction #1 [01000001];[01000010] (This is "A" "B" in binary)

Instruction #2 [01000010];[01000001] (This is "B" "A" in binary)

Output

A 32-bit processor does lit like this:

Receive command

Instruction #1 [01000001];[01000010];[01000010];[01000001] ("ABBA" in Binary)

Output

A lot more goes into the actual process than this, and a 32-bit processor isn't necessarily twice as fast at the same clock speed as a 16-bit processor. In fact, real world differences are quite small, due to some under-the-hood architectural differences between 16, 32, and 64 bit processors. Just keep in mind a lower-bit processor isn't compatible with a higher-bit program, but most higher-bit processors ARE compatible with lower-bit programs.

Answer 4

n-bit microprocessor means how many bit can a microprocessor can process i.e as the operations.8bit means that microprocessor can process only 8bit addition , subtraction etc as in case.16 bit can process data of 16bit for any kind of operation to be performed.naturally the greater the number of bits to be processed the good it is.

an eg of 8bit-8085

an eg of 16bit-8086

both if intel

Answer 5

A 16-bit microprocessor is (generally) faster than an 8-bit microprocessor because it handles 16-bits at a time instead of 8-bits at a time.

The data transfer rate into and out of memory is doubled and the processing to handle multiple precision data is (approximately) halved. The 16-bit microprocessor also (usually) has more advanced instructions that can do more than the 8-bit microprocessor.

Answer 6

There are many differences between an 8-bit and 16-bit microcontroller. The biggest is speed and computing - the 16-bit is faster and more advanced. In turn, the 16-bit is also more expensive.

Answer 7

8-bitIn computer architecture, 8-bit integers, memory addresses, or other data units are those that are at most 8 bits (1 octet) wide.

Also, 8-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.

8-bit is also a term given to a generation of microcomputers in which 8-bit microprocessors were the norm.

8bit can process only 8bit addition , subtraction etc. 16-bitIn computer architecture, 16-bit integers, memory addresses, or other data units are those that are at most 16 bits (2 octets) wide.

Also, 16-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.

16-bit is also a term given to a generation of microcomputers in which 16-bit microprocessors were the norm.

16 bit can process data of 16bit for any kind of operation to be performed

Answer 8

8 bit computer can only display 256 colors while a 16 bit computer can display 64,000 colors.
