Most everyone knows how to use a keyboard and mouse, as well as speakers and batteries. Printers and scanners are also very common computer supplies; some printers are combined with a scanner and a fax to make the machine a 3-in-1 printer. Portable projectors and USB flash drives are also fairly common. Some people may not be as familiar with computer supplies such as a webcam, a network attached storage device, an optical drive, or an external hard drive.
A webcam is a digital camera whose images are transmitted over the World Wide Web. A webcam is a small camera that usually plugs into a USB port of a computer. A webcam is useful because it allows people to see each other on camera instead of just hearing each other's voices. Businesses often use webcams to hold video conferences.
External hard drives:
Most computers come with internal hard drives which provide the best performance; however, there are many reasons to use an external drive with your computer. You can connect an external hard drive to your computer using a USB port. One of the main reasons to use an external hard drive is to provide extra storage. Another reason to use an external hard drive is for backup purposes. External hard drives are often the easiest and fastest way to transfer large files between computers.
Network attached storage:
Network attached storage (NAS) is a storage enclosure that holds a large amount of RAID disk and is directly attached to a computer network. The NAS does not need a dedicated computer to run on; it contains its own network interface card.
An optical disc drive is a disk drive that uses laser light or electromagnetic waves as a part of the process of reading or writing data to or from optical discs. DVDs, Blu-ray discs, and compact discs are common types of optical media which can be read and recorded by optical drives.
For businesses, keeping enough computer supplies in stock is important; for home users it is often important to be able to order the right computer supplies and receive them in a timely manner.
