Why memory stick of mobile, camera comes like 32, 64, 128 MB insted of 10,20,40 MB?

Answer 1

the simplist answers is that computers use binary numbers and bits and bytes. Binary is just 0,1's. It is base 2 number system.
2^1=2
2^2=4
2^3=8
2^4=16
2^5=32
2^6=64
2^7=128 and so on and so forth. its just a way for computers to store data.

Answer 2

It's an economical/technological reason.

Because the adress lines on the circuitry and inside the chips work in binary too, the maximum count of memory cells which can be adressed is always a power of 2.

So the complexity, thus the cost, of a 60MB chip would be exactly identical to the 64MB one. Which one would a customer buy for the same price, 60 or 64MB? So nobody will produce 60MB chips...

BTW, here MB = 1,048,576 bytes, not 1,000,000, and it is a bad habit of the chip makers, because the correct term for 1,048,576 bytes is MiB, Mebibyte, and not MB megabyte. But (almost) everyone use MB instead of MiB...

Answer 3

you have become taken for a journey. do no longer waste your money on that comp. counting on what you're certainly finding for in a working laptop or computer (e mail, chat, some information superhighway surfing, be conscious processing, etc.), you would be waiting to get a computer and reveal screen for around $500 - $seven-hundred. in case you be conscious of a nerd who can build it for you, perhaps $4 hundred. Going with a Mac... you may smash out with around $800 for a Mac Mini and an Acer widescreen reveal screen. iMac would be over a grand, and you will nevertheless be dropping your money.

Answer 4

Because computer RAM is binary, and hence is traditionally parceled up in powers of two, and memory sticks are more like RAM than they are like hard disks.

It's arbitrary, though. They could make 20MB or 40MB flash memory if they wanted to.

Answer 5

What I talk like a kid, is -- "We are talking of Multiples Of FOUR" and much of the Systems in the world these days work DIGITALLY in Symbols of FOUR (Dits and Dahs). One needs to STUDY this FACT and I Put It aside in the BEGINING.

Answer 6

Because digitals are essential computers, so it is following computing protocols; that why chunks of space like 256, 512 etc.

Answer 7

maybe you have some sort of an error in your camera like the pixels
are damaged in your camera

Answer 8

'Coz its easy to compare with other memory devices while making ur purchase!
