Different Types of Computers
Personal Computer (PC)
Personal Computer (PC)
A PC is a small computer that fits on a desk and
is used by one person. It is based on the
microprocessor technology that enables
manufactures to put an entire computerprocessing unit (CPU) on one chip, which acts as
the brain of the computer, telling each part what
action to perform. A desktop computer running
Windows is often referred to as a PC, but Apple
computers are also technically PCs.
Laptop / Notebook Computer
Laptop / Notebook Computer
A laptop is a portable computer that integrates a
display, keyboard, processor, memory, hard
drive, and pointing device all in a batteryoperated package. In terms of computing power,
modern laptops are nearly equivalent to PCs.
While they can have the same speed and
memory as a PC, all that power in a small
package makes them more expensive.
Smartphone / Tablet
Smartphone / Tablet
Smartphones and tablets are hand-held
computing devices that run an operating system
and series of applications. Generally controlled
by a touch screen input, the modern generation
is capable of many of the same tasks as PCs and
laptops. The biggest disadvantage is the inability
to perform certain tasks without connecting
external peripherals.
Workstation
Workstation
A workstation is more powerful and faster than
most personal computers. It is typically used for
graphics, scientific computing, computer
assisted design (CAD), and other applications
requiring high performance and memory. Like
PCs, most workstations are used be one person.
Server
Server
A server is a computer that has been optimized
to provide services to other computers over a
network. It can carry out more than one
program or instruction at the same time,
allowing it to support hundreds of users at once.
People login to the server by typing in a
username and password and then access the
applications and documents while working from
their PC.
Supercomputer
Supercomputer
A supercomputer is the fastest type of
computer. They are very expensive and are
employed for specialized applications that
require immense amounts of mathematical
calculations. Examples of tasks include weather
forecasting, fluid dynamic calculations, nuclear
energy research, and petroleum exploration.
