Table 1 summarizes the most common representations of groups of bits, and the terms used for them; their relative sizes are also shown graphically in Figure 8.
A few of these terms are worth special mention. Bit and byte we have already discussed, of course. A bit is also sometimes called a flag ; this term is most often heard when a bit is used by itself to represent a particular information state. The term character is also used to express a set of eight bits. This use comes from the fact that computers often store alphanumeric characters, such as letters and numbers, one to a byte.
The larger collections of bits, such as double word and so on, are not often encountered in every-day parlance; they are used to represent chunks of data in technical fields such as hardware design or programming. Figure 8: Binary Information Representations and Terms.
You may also have noticed the number of bits used for each of these terms is a power of two. This is of course not a coincidence. As we will see in the subsequent topics in this section, this occurs because when bits come in sets that are a power of two in size, they are easier to represent and manipulate in a convenient manner. The number of bits in the term can itself be easily expressed using binary numbers. This will make more sense after you read the topic that follows on decimal binary, octal and hexadecimal numbers.
Nibble consist of 4- Bit. Byte consist of 8- bit. In computers and digital technology, a nibble pronounced NIHB-uhl; sometimes spelled nybble is four binary digits or half of an eight-bit byte. A signal may be encoded in quadbits rather than one bit at a time.
In computing , a word is the natural unit of data used by a particular processor design. A word is a fixed-sized piece of data handled as a unit by the instruction set or the hardware of the processor. Each 1 or 0 in a binary number is called a bit. From there, a group of 4 bits is called a nibble, and 8- bits makes a byte. Bytes are a pretty common buzzword when working in binary.
Processors are all built to work with a set length of bits , which is usually this length is a multiple of a byte: 8, 16, 32, 64, etc. From there, a group of 4bits is called a nibble, and 8-bitsmakes a byte. It could be 16 - bits , 32, 64, or even more.
The nibble is used to describe the amount of memory used to store a digit of a number stored in packed decimal format BCD within an IBM mainframe. This technique is used to make computations faster and debugging easier. An 8-bit byte is split in half and each nibble is used to store one decimal digit. Answer: Two bits is commonly understood in America to be one quarter. How much is 1 byte, kilobyte, megabyte, gigabyte, etc.? A nibble is 4 bits. Today, a byte is 8 bits.
Kilobyte KB A kilobyte is 1, bytes. Megabyte MB A megabyte is 1,, bytes or 1, kilobytes. Gigabyte GB A gigabyte is 1,,, 2 30 bytes. A collection of eight bits is called Byte.
Somebody made a joke about a group carrying a byte of the data , and the term stuck. Sometimes you hear a group of four bits called a nibble. The largest number you can represent with 8 bits is , or in decimal notation. A bit short for "binary digit" is the smallest unit of measurement used to quantify computer data. For example , a small text file that is 4 KB in size contains 4, bytes, or 32, bits.
