Dvd full form in computer

DVDs VS CDs. Digital versatile discs (DVDs) can store more information than compact discs (CDs) because they have smaller pits, placed closer together. It is the pattern of these pits burned onto a disc's surface that encodes the 1's and 0's a player translates into sound and/or images. The tools of technology can seem like a confusing alphabet-soup. Terms such as ZIP, CD or DVD are commonly used to describe the means available for storing and sharing information, ranging from text to audio to full-length films. Of them all, DVD, which stands for digital versatile disc, is poised to become the most popular and reliable means for storing data, especially high-quality digital video. DVDs are now rapidly making their way into American homes as the state-of-the-art entertainment option for watching Hollywood releases. Before going into the mechanics of how a DVD works, it might be best to explain the why. In other words, why is the industry replacing previous storage-unit standards, including the CD (short for compact disc)? Quite simply, the DVD's storage capacity is much greater. Thus, the DVD makes sense for video and other industries in a way that the CD never could. A high-quality digital video could simply never fit onto a CD. It can't even fit comfortably on a computer hard drive. Indeed, a high-quality digital video requires up to 100 megabytes (MB) of data space each minute, depending on the amount of compression used. MPEG2, a format commonly used for playing video v...

A computer refers to a machine that is assembled using different physical parts or components and programmed with different languages to carry out a set of algorithms and arithmetic instructions. Currently, computers have become part of the human need to help people perform many tasks easily. When it comes to assembling a computer system, there are several parts of a computer that we must connect to form a typical, present-day computer. Each part has an important role and helps to process/perform a specific task when we operate the computer. For a computer system to operate, some basic parts are required such as a mouse, keyboard, monitor, power cord, and computer case as well as its internal components. How many parts of computers are there? A computer is made up of different parts, whether it is small or large. Some parts can be easily recognized and physically touched. However, there are many different parts that cannot be touched until the computer system is completely disassembled. Based on the touch and viewing characteristics, computer parts are generally divided into internal and external. Note: Due to differences in the size of computer systems (or desktops) and laptops, basic parts differ in both size and design. However, many of the same parts are used in both these types of computers. A laptop consists of the same parts as a computer; but, integrated into a single, small, portable unit.

What is the full form of CD and DVD? CD is Compact Disc (CD) DVD is Digital Versatile Disc (DVD) For long-term data and information storage in computers, various secondary storage devices, including CDs, DVDs, HDDs, etc. The operation of optical storage systems like CDs and DVDs is based on optical effects. Red LASER is used for read and write operations on CD and DVD. They do, however, differ greatly from one another in several ways. Compact Disc (CD) Small plastic discs called Compact Discs (CDs) are used to store and playback music or computer data. It was created by Philips and Sony in collaboration and introduced as a digital optical disc data storage format in 1982. Because they were speedier and more information-capable than floppy discs, compact discs took their place of them. Up to 80 minutes of music can fit on a CD, which has a maximum data capacity of 700 MB. Computers utilize CDs to store data and information permanently. It may be removed from the computer without the use of any tools, indicating that it is an external storage device. As a secondary memory device that stores data that the CPU isn't currently processing, CDs are also included in this category. For a long time, CDs were utilized in place of memory/magnetic devices. It's because they used to provide inexpensive solutions to those looking to store big amounts of data or video. The data on a CD is read and written using laser light. When the targeted area of the CD reflects the laser beam, the pho...
