Aug 21, 2024 · A group of eight bits is known as a Byte. 1 Byte can represent numbers between zero (00000000) and 255 (11111111), or 2 8 = 256 distinct positions. Of course, these bytes may also be combined to represent larger numbers. The computer represents all characters and numbers internally in the same fashion.
Try this experiment: Open up a new file in Notepad and insert the sentence, "Four score and seven years ago" in it. Save the file to disk under the name getty.txt. Then use the explorer and look at the size of the file. You will find that the file has a size of 30 bytes on disk: 1 byte for each character.
Mar 3, 2021 · Byte and Bytes! When we combine eight bits together, we form a byte. A byte is a human concept, not one which a computer can understand at it cores. Very early computer developers decided to create bytes out of 8 bits. Let's see how many combinations we can create using eight bits, set to a state of 0 or 1: 0000 0000 = 0. 0000 0001 = 1.
a "bit" is atomic: the smallest unit of storage. A bit stores just a 0 or 1. "In the computer it's all 0's and 1's" ... bits. Anything with two separate states can store 1 bit. In a chip: electric charge = 0/1. In a hard drive: spots of North/South magnetism = 0/1. A bit is too small to be much use. Group 8 bits together to make 1 byte.
Most modern computers only allow a program to access a byte, which is a contiguous group of eight bits. Historically, the number of bits in a byte has varied depending on the hardware and the operating system. For example, the CDC 6000 series of scientific mainframe computers used a six-bit byte.
The bit is the most basic unit of information in computing and digital communication. The name is a portmanteau of binary digit. [ 1 ] The bit represents a logical state with one of two possible values. These values are most commonly represented as either "1" or "0", but other representations such as true / false, yes / no, on / off, or + / − ...

For a computer system using a 32 bit-wide “data path,” a “word” would mean 32 bits. If the system used 16 bits as the standard grouping for binary quantities, a “word” would mean 16 bits. The terms playte and dynner, by contrast, always refer to 16 and 32 bits, respectively, regardless of the system context in which they are used.
