what is a bits?

Answer 1

A bit is the most basic form of data in a computer. Computers use binary counting which uses just ones and zeros. Computers logic is made up of millions of tiny switches. Each switch can represent one bit of data. The switch may either be in a high or low state (on or off). In a 64 bit processor, 64 of these switches are read at one time and each switch my be high (1) or low (0). Each time it changes it represents on bit of data. When the processor looks at all the switches at one time, the different order of high and low for each switch combined represents different information, just like words are made up of different letters in a certain order. In computers, this group of bits can represent a byte of information, which is similar to a word. In actuality, each letter of the alphabet is made up of several bits in different states of high or low so the computer knows the difference. The more bits a computer can process at one time, the faster it can become.

Answer 2

A bit is a single yes/no or on/off signal for a computer. 8 bits make a byte, and so on with the labeling. Computers speak binary, the essence of a bit.

I hope this helps.

Answer 3

in binary is means '1'. 1 byte have 8 bits, so mean '11111111' in binary, if in decimal it become 255.
