A little bit is the least amount of data in the computer. The pieces have a single binary value, 0 or 1. The computer typically provides instructions for manipulating and manipulating bits, but is typical for storing data and instructions for accessing a plurality of pieces, referred to as bytes. Boolean operators are simple words (AND, OR, XOR and NOT). Add this search term or exclude search terms when searching for productive results. Avoid inappropriate movements and save time and energy. It has to be scanned before it is destroyed. AND indicate that one acknowledgment is true and the other is false. OR to suggest a statement is correct. XOR represents only one statement is true. Do not display, we enter an entry and then enter the output of the contrast. A device that leaves us when we return. It’s called Gates. A circuit group is known as a flip-flop. The data that stores a computer covers a large number of circuits (such as slippers), each of which can store a single part. This pole is referred to as the main memory of the machine. The main memory of a computer in controlled units has this unit known as a cell. Each cell contains 8 bits and 8 bits corresponds to one byte. In a computer, there are no left and right. The bits place them in a row. The left hand of this series has its famous high end and the other side is the bottom end.To classify certain cells in the main memory of a computer, each cell is assigned an unusual “name”, an address. The main memory of the computer is controlled as specific addressable cells, cells can be independently retrieved as needed. The ability to access cells in both directions is the main memory of the RAM (RAM) known to the computer. Due to the limitation of the data stored in the computer and the volatility of the data, especially in computers. A spin conductor is provided with a magnetic layer for reading and writing data known as magnetic disks. Another class of mass systems uses optical technology. An example is the CD (CD). The information is recorded on them by generating variations in their reflective areas. This information can then be recovered using a laser beam that detects irregularities on the reflective surface of the CD during rotation. Storage of data in the form of a group as an important unit. It is said that the file of this code not only detects the error, but also corrects the error, the so-called error code. Code coded in audio and video. This code is called MPEG. The images usually encode in GIF. how data can be coded as a small model. Our study focuses on common coding methods for text, digital data, images and audio. Each of these systems has effects that are often visible to a typical computer user. The textual information is generally entered by a code containing each of the various textual symbols (such as letters of the alphabet and the punctuation) associated with a single sample piece. The text is then displayed as a long sequence in which the sequential patterns consist of successive symbols in the original text, the information in the form of stored coded characters, and ineffective if the recorded information is purely numerical. Consider the problem of storing the value 25. If we insist on storing it as ASCII-encoded symbols with one byte per symbol, we need a total of 16 bits. The largest number we can record with 16 bits is 99.One way to represent an image is to interpret the image as a collection of points. The appearance of each pixel is then encoded and the entire image is displayed as a collection of those encoded pixels. Such a collection is called a bitmap.
