Why are computers based on 8 bits?
The reason computers use the base-2 system is because it makes it a lot easier to implement them with current electronic technology. They are almost always bundled together into 8-bit collections, and these collections are called bytes. …
Why is memory always in multiples of 2?
Memory is closely tied to the CPU, so making their size a power of two means that multiple modules can be packed requiring a minimum of logic in order to switch between them; only a few bits from the end need to be checked (since the binary representation of the size is 1000…
Why is storage an even number?
It only comes in even number because computers only understand binary numbers (0’s and 1’s). So, binary numbers have base 2. This is why memory only comes in even numbers.
Why are page sizes always power of 2?
Because each bit position represents a power of 2, splitting an address between bits results in a page size that is a power of 2. …
What is the typical amount of RAM and hard drive size in a computer?
Currently, RAM size ranges from 256MB to 32GB. The size of the hard drive that is accessible spans from 500GB to 8TB. The hard disk is more like a machine with different parts like the writer and reader module while RAM is a minor (silicon) chip consisting of circuits.
Is it bad to have an odd number of RAM?
Yes. Dual channel is something that requires pairs of modules. So you need a multiple of two for all sticks to run in dual channel mode.
What are the factors and multiples of 8?
The factors of 8 are 1, 2, 4, and 8. The multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88,….
Why is computer memory always in multiples of 8?
ELI5: Why is computer memory always in multiples of 8? (8, 16, 32, 64, 128, 256, etc.) Because those numbers are powers of two. Computers address memory (and do everything else) with binary numbers. It makes sense to have memory in amounts that line up with powers of two because there’s no saving in address space if it doesn’t.
Why is data stored in multiples of 8?
It’s not in multiples of 8, it’s in powers of 2. And it’s in powers of 2 because of bits. Computers use bits (1’s and 0’s or high and low voltage) for everything so you can only store in powers of 2. So it’s 1, 2, 4, 8, 16, 32, 64, 128, etc.
Why does the memory size line up with the power of two?
It is Because those numbers are powers of two. Computers address memory (and do everything else) with binary numbers. It makes sense to have memory in amounts that line up with powers of two because there’s no saving in address space if it doesn’t. That is, 7KB takes just as much address space as 8KB.
Why does 7Kb of memory have a power of 2?
Computers address memory (and do everything else) with binary numbers. It makes sense to have memory in amounts that line up with powers of two because there’s no saving in address space if it doesn’t. That is, 7KB takes just as much address space as 8KB. It’s not in multiples of 8, it’s in powers of 2. And it’s in powers of 2 because of bits.
