No, CD (Compact Disk) technologies store data bits as reflective (or non reflective) pits in an optically (not magnetically) read substrate.
Hard disks, floppy disks and magnetic tapes store bits as tiny magnetized areas.
Yes. As magnetized north or south binary bits.
8 bits if unsigned, 9 bits if signed
23 can be represented in binary as 10111 and would therefore require 5 bits to represent.
9 bits
Binary bits are necessary to represent 748 different numbers in the sense that binary bits are represented in digital wave form. Binary bits also have an exponent of one.
Most modern digital cameras use 24 bits (8 bits per primary) to represent a color. But more or less can be used, depending on the quality desired. Many early computer graphics cards used only 4 bits to represent a color.
Four bytes represent 32 bits. 32 bits represent 4,294,967,296 possibilities.
Well, honey, to represent months of the year, you need at least 4 bits because you've got 12 months in a year, and you need 4 bits to represent numbers from 0 to 15. So, technically, you could do it with just 4 bits, but if you want to be fancy, you could use 5 bits for a more efficient representation.
A series of bits is actually a lot of data sent though the computer to little information holds on a disk or something that stores data. The bits can be comprised of anything from keystrokes to pictures to movies and music.
To represent 64 characters, you would need 6 bits. This is because 2^6 equals 64, meaning six bits can encode 64 different values, sufficient for each character. Each bit can represent two states (0 or 1), and with six bits, you can create combinations to represent all 64 characters.
4.1 bit for 2,2 bits for 4,3 bits for 8,4 bits for 16.
