# Byte

### What is a byte?

Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures.

### What is the value of a bit in computer?

A bit is a value of either a 1 or 0 (on or off). A nibble is 4 bits. Today, a byte is 8 bits. 1 character, e.g., a, is one byte. A kilobyte is 1,024 bytes. 2 or 3 paragraphs of text. A megabyte is 1,048,576 bytes or 1,024 kilobytes. 873 pages of plain text (1,200 characters).

### What is the difference between a KB and a byte?

For example, a kilobyte (KB) is different than a kilobit (Kb). When referring to storage, bytes are used whereas data transmission speeds are measured in bits. A bit is a value of either a 1 or 0 (on or off). A nibble is 4 bits. Today, a byte is 8 bits. 1 character, e.g., a, is one byte. A kilobyte is 1,024 bytes.

### How many bits are in a byte in C++?

Various implementations of C and C++ reserve 8, 9, 16, 32, or 36 bits for the storage of a byte. In addition, the C and C++ standards require that there are no gaps between two bytes. This means every bit in memory is part of a byte.

### How many bytes are in a KB?

If it is listed as KB (uppercase k), it is a binary kilobyte and is 1024 bytes. 1 KB = 1KiB (kibobyte) = 1024 bytes. And yes, the k can be capitalized.

### What is the difference between KB and KBK?

kilo no matter if its bytes or bits is ALWAYS lower case or no caps. Actually, a kilobyte can be 1000 bytes or 1024 bytes. If it is listed as kB (lowercase k), it is a decimal kilobyte and is 1000 bytes. If it is listed as KB (uppercase k), it is a binary kilobyte and is 1024 bytes.

### What is the difference between Megabyte and kilobyte?

It antecedes the MegaByte, which contains 1, 000, 000 bytes. One kilobyte is technically 1, 000 bytes, therefore, kilobytes are often used synonymously with kibibytes, which contain exactly 1, 024 bytes (2 10 ). Kilobytes are mostly used to measure the size of small files.

### What is the difference between MB and KB in Linux?

The difference between MB and KB is that a single kilobyte (KB) is composed of one thousand bytes, while a MB consists of one million bytes. According to this rule, a 1 MB file is 1,000 times smaller than a 1 KB file.
