Keyboard
Keyboard - The keyboard is used to type
information into the computer or input information. There are many different
keyboard layouts and sizes with the most common for Latin based languages being
the QWERTY layout (named for the first 6 keys). The standard keyboard has 101
keys. Notebooks have embedded keys accessible by special keys or by pressing
key combinations (CTRL or Command and P for example). Ergonomically designed
keyboards are designed to make typing easier. Hand held devices have various
and different keyboard configurations and touch screens.
Some of the keys have a special use. They
are referred to as command keys. The 3 most common are the Control or CTRL,
Alternate or Alt and the Shift keys though there can be more (the Windows key
for example or the Command key). Each key on a standard keyboard has one or two
characters. Press the key to get the lower character and hold Shift to get the
upper.
Removable Storage and/or Disk Drives - All
disks need a drive to get information off - or read - and put information on
the disk - or write. Each drive is designed for a specific type of disk whether
it is a CD, DVD, hard disk or floppy. Often the term 'disk' and 'drive' are
used to describe the same thing but it helps to understand that the disk is the
storage device which contains computer files - or software - and the drive is
the mechanism that runs the disk.
