Wed ,30/06/2010Also known as the hard disk drive or HDD, the computer hard drive basically stores data. The least number of hard disk units a system can have is one. Larger computer systems can use up to a hundred hard drives. Unless tampered with, the basic function of a hard drive is to store information in digital form. As long as the information has entered into the HDD, it is safe even if power goes out. The position of the hard drive is toward the front of the computer in an air-tight casing. Downloaded Performance enhancing information from the Internet and other media can improve the performance of a hard drive. A folder in the HDD stores this information as temporary Internet files. With the information already on your hard disk you can easily gain access to the website of your choice whenever you are ready. Accumulating these temporary files on the computer tends to slow it down so they will need to be deleted from time to time. The IDE and SCSI stand as the recognized standards for transferring information between hard disk and the rest of the computer. Winchester is another name by which hard drives go. The name is the same as that of the first hard drive produced way back in the early 70s by IBM. Most desktop computers have as little as less than 10 gigabytes of storage and as many as 40. A byte is the unit for stored data in a hard drive, a collection of which is called a file. Colors, imagery, records and software applications all present themselves in form of bytes to the hard drive. The workings of a computer simulate an automobile where fuel (stored up information in bytes) is pulled and channeled into the engine (the CPU) where it is burned to move the vehicle. The role of magnetism is a computer hard drive is easily apparent in the extraction of input from the platter in small particles. As the hard drive rapidly spins, it generates a magnetic flux that pulls on the small particles incident on the platter by finding their respective polarities.
