What is Bit and Byte?
Let’s see what a bit and byte are. A bit, the smallest unit that measures the amount of information. One contains little information as opposed to a group of bits. In a computer, all data is stored and processed in the form of characters. Only two characters are usually used – the numbers 0 and 1. The combination of these two numbers is called a binary code, and the numbers themselves are usually called binary numbers or short bits. A computer distinguishes between 0 and 1 due to electrical impulses in electronic circuits. If there is no impulse in the circuit, this is the digit 0, if there is a pulse, then this is 1. Thus, in the form of a combination of 0 and 1, absolutely all information is stored inside the computer, from photos to music. Along with the notion of bits, the notion of bytes is used.
A set of 8-bit computer data is called a byte. 8 bits provide the basis for representing characters, such as the letter “A” and binary arithmetic. That is, a byte is a command of bits responsible for a particular part in a file. Each byte has a unique address in the computer’s memory. By convention, the bits and bytes are numbered from 0 to 7 from right to left. For example: the bit number is 76543210, and its value is 0 1 0 0 0 0 0 1 and as a result, if you transmit this value to the printer, the letter “A” will be generated there. The number of bits included in the byte must be odd. When a command is addressed to a byte, the computer checks this byte and if the number of bits included is even, the system gives an error. A parity error may be the result of a hardware failure or an accidental occurrence, but this happens very rarely.
During data processing, electrical impulses pass through the electronic circuits in the computer. Circuits are made up of conductors and electronic micro devices called logic gates. Impulses passing through these valves can be “quenched”. Thus, the data is processed. Combining logic gates, complex combinations are created that perform operations — they memorize, compare, add, compare numbers, and so on.
In the silicon plates are electronic circuits. Each microcircuit can contain more than a million circuits, the type of work they perform depends on the location.
Chips are located on special plates, namely on printed circuit boards. The strip itself is printed on the board, through which the electricity passes to the microcircuits. Metal lanes, which are called tires, transmit bytes, each bus contains several such tracks. One track transmits one byte.
Tires are divided into three types: data bus, control and address bus. The data bus communicates between the processor and input devices, between the processor and the computer’s memory. Instructions from the processor to all nodes of the computer are transmitted via the control bus. Information about the location or address of the data is transmitted via the address bus.
Bit and byte are rather small values, so they are used with prefixes kilo, mega and giga. Let’s now talk about the magnitude that measures the speed of the Internet. Internet speed is the amount of information sent and received by your personal computer per unit of time. The quality of a unit of time is a second, and the quality of the amount of information received is a kilobit or megabit. For example, if your speed shows 128 Kbps, it means that your connection skips 128 kilobits, which equates to 16 kilobytes. In order to find out a lot of this or a little, use the tests to determine the speed of connection to the Internet.
