File compression is used when sending a file from one computer to another over a connection that has limited bandwidth. It makes the file smaller and, therefore, the sending of the file is faster. It includes software programs that will archive your files and extract archived files such as ZIP and RAR files.
A serious disk drive malfunction. A head crash means that the head has scratched or burned the disk. If the head becomes misaligned or if dust particles come between it and the disk, it can touch the disk. When this happens, you usually lose much of the data on the hard disk and will need to replace both the head and the disk.
Internet hard drives have served to meet this need, offering a creative new solution to the issue of data storage. The purpose of an Internet hard drive is to offer a means of accessing your computer files from any computer, as long as that computer has access to the Internet.
Optical disk is an electronic data storage medium from which data is read and written to by using a low-powered laser beam. It retrieve or store data on optical discs like CDs, DVDs, and Blu-ray discs. They hold much more information than the floppy disk. Most optical drives can play or record onto a large number of different disc formats.
Solid-state storage is a nonvolatile, removable storage medium that employs integrated circuits rather than magnetic or optical media. The advantage of solid-state storage is it contains no mechanical parts. Data transfer to and from solid-state storage media takes place at a much higher speed than is possible with electromechanical disk drives. The example of solid-state storage is flash memory Universal Serial Bus (USB) devices.
