10 Types of Computers
There are a lot of terms used to describe computers. Most of
these words imply the size, expected use or capability of the
computer. While the term computer can apply to virtually any
device that has a microprocessor in it, most people think of
a computer as a device that receives input from the user
through a mouse or keyboard, processes it in some fashion and
displays the result on a screen.
Do you know the different types of computers?
1.PC
The personal computer (PC) defines a computer designed for
general use by a single person. While a Mac is a PC, most
people relate the term with systems that run the Windows
operating system. PCs were first known as microcomputers
because they were a complete computer but built on a smaller
scale than the huge systems in use by most businesses.
2. Desktop
A PC that is not designed for portability is a desktop
computer. The expectation with desktop systems are that you
will set the computer up in a permanent location. Most
desktops offer more power, storage and versatility for less
cost than their portable brethren.
3. Laptop
Also called notebooks, laptops are portable computers that
integrate the display, keyboard, a pointing device or
trackball, processor, memory and hard drive all in
a battery-operated package slightly larger than an average
hardcover book.
4. PDA
Personal Digital Assistants (PDAs) are tightly integrated
computers that often use flash memory instead of a hard drive
for storage. These computers usually do not have keyboards
but rely on touchscreen technology for user input. PDAs are
typically smaller than a paperback novel, very lightweight
with a reasonable battery life. A slightly larger and heavier
version of the PDA is the handheld computer.
5. Workstation
The fifth type of computer is a workstation. A workstation is
simply a desktop computer that has a more powerful processor,
additional memory and enhanced capabilities for performing
a special group of task, such as 3D Graphics or game
development.
