A additional storage device. This is called mass storage.

A littleis the small amount of data on the computer. The bits have to provide single binary value 0 or 1computers in general forthe available control and manipulatethe bits, but they usuallyrefer to the data forstorage and many instructions for accessing the bit bytes.Boolean operatorsare linked or excludesimple words(AND, OR, XOR and NOT), the search terms in the search results searchresults. Avoid inappropriate movements and save time andenergy. It has to be scanned before being destroyed.

And declares that anacknowledgment is true and the other is false. Or, to represent a statement iscorrect. In XOR, only one statement is true.

It is NOT shown, we enter an entryand then we specify the contrast value. A device that gives us an exit when wegive feedback. Its name is Gates. A group of circuits is known as a flip-flop.To store data, a computer includes a large group of circuits (such asflip-flops), which store each one suitable for a single bit. Thistank is called the mainmemory ofthe machine.

 The mainmemory ofa computer is organized in controllable units.This unit is called a cell. Each cell consists of 8 bits and8bits of a byte. In a computer, there isno left or right. Thebits are arranged in arow. The leftside of thisseries iscalled the end of the top order, and the other end is the end of the low order.To classify specific cellsin the main memory of a computer, each cellreceives aunique name called an address. The main memory of the computer is organizedinto specific addressable cells, the cells can be retrieved independently asneeded.

To demonstrate the ability to access cells in any way, the main memory of a computer is itsknown RAM. Due to the limitation ofthe restriction of commercial data on the computer and the volatility of data, mostcomputers have an additional storage device.This is called mass storage. A rotatingdisk is covered with amagnetic coating. It isused to read and write data calledmagnetic disks.

 Another class of mass storage systems usesvisual technology. An example isthe CD (CD). Theinformation is recorded by generating variations intheir reflective surfaces. This information can then be recovered by means of alaser beam which detectsirregularities inthe reflective surface of the CDduring its rotation. A flash drive is an ultraportable device. It is very smalland different from an optical orconventional hard disk. Thisdevice isthe combination of aUSB device and a cable. Storageof data in the form of a group as an important unit.

 This is called a file. The technique used to transferand store data. Reduce data size this is calleddata compression. Thecode not only detects errors butalso corrects errors, itsknown error correction code.The code encoded in audiosand videos.

This code is called MPEG. The images usually encode in GIF. Howdata can be encoded as a binary model. Our study focuses on common methods ofcoding digital text, images and sound data. Each of these systems has effectsthat are often visible to atypical computer user.

 The textual information is generally represented by a code inwhich each of the different text indications (such as the letters of thealphabet and the punctuation marks) is associated with an unusual bit pattern.The text is shown below, inthe form of along bit sequencein which the successivedrawings represent the successivescreen inthe original text of the store in the form of ineffectivecoded characters when the informationto be recorded is purelydigital. . Suppose the problem isto record the number25. If we insist on storing them as ASCII-encoded symbols using one byte persymbol, we needa total of 16bits. In addition, the largest numberwe could store with16 bits is99. One way to represent an image isto interpret the image as a collection of points.

The appearance ofeach pixel is encodedand the entireimage is displayedas a collection of these encoded pixels. Such a collection iscalled Bitmaps.
