Categories of Computers
Personal computersPersonal computers are desktop computers
designed for an individual's use. They run
programs designed to help individuals
accomplish their work more productively.
Servers
Servers are not designed to be used
directly. They make programs and
data available for people hooked up to
a computer network, a collection of
computers connected together so that
they can exchange data.

MinicomputersComputer that is smaller, less expensive, and less
powerful than a mainframe or supercomputer, but
more expensive and more powerful than a
personal computer. Minicomputers are used for
scientific and engineering computations, business-
transaction processing, file handling, and database
management, and are often now referred to as
small or midsize servers.
Mainframes
Mainframes are huge, multi-user systemsdesigned to handle gigantic processing jobs in
large corporations or government agencies. A
powerful multi-user computer capable of
supporting many hundreds or thousands of
users simultaneously.

Supercomputers
The fastest type of computer. Supercomputers are very
expensive and are employed for specialized applications
that require immense amounts of mathematical
calculations. For example, weather forecasting requiresa supercomputer. Other uses of supercomputers include
animated graphics, fluid dynamic calculations, nuclear
energy research, and petroleum exploration

Laptop
A laptop computeris a personal computer for
mobile use. A laptop utilizes most of the same
components as a desktop computer, including a
display , a keyboard , a pointing device such as atouchpad (also known as a trackpad) and/or a
pointing stick , and speakers into a single unit.
A laptop is powered by mains electricity via an
Ac Adapter, and can be used away from an outlet
using a rechargable battery.
Laptops are also sometimes called notebook
computers, notebooksor netbooks.

Computer System and Programs
A computer system consists of hardware andsoftware
Hardware is the physical equipment such as the case, floppy
disk drives,keyboard, monitor, printers
Software describes the programs that are used to operate the
computer system. It is also called programs, instructthe computer on how to operate.

CPUs have three basic parts
1. The Arithmetic Logic Unit (ALU)does all of the mathematics in a computer
does all of the logic comparisons of values
some common logic comparison symbols
= equal to < less than
> greater than = greater than or equal to not equal
2. The Control Unit
directs the flow of information into the CPU and/or memory or storage
controls which instructions the CPU will do next
3. Registers
Used to store data and instructions inside the processor
Size of the registers can affect the speed and performance of the
processor

A computer system unit contains many parts.
Motherboard- The motherboard is the main
circuit board of a microcomputer. It is alsoknown as the mainboard or system board.
CPU- The CPU is the central electronic chip
that determines the processing power of the
computer.
Memory- Memory is the part of the computer
that temporarily stores applications,
documents, and stem operating information.
Bus- A bus is an electronic line that allows 1sand 0s to move from one place to another.
Expansion Slots- Expansions slots appear
on the motherboard. They are sockets into
which adapters are connected.
Ports and Connectors- A port is a connector
located on the motherboard or on a separate
adapter.Bays- A bay is a space inside the computer
case where a hard drive, floppy drive or CD-
ROM drive sits
Power Supply- A power supply changes
normal household electricity into electricity
that a computer can use.

Primary storage Main internal storage of a computer . Primary storage is used to
store data that is likely to be in active use.
2 types of primary storage:
RAM(random Access Memory)
Temporary memory
is a volatile
the information is lost after the power is switched off.
ROM(Read Only Memory)
Permanent storage
data stored in ROM cannot be modified
is not volatile, but is not suited to storage of large quantities of data because it
is expensive to produce.

A network consists of two or more computers thatare linked in order to share resources (such as
printers and CD-ROMs), exchange files, or allow
electronic communications.
The computers on a network may be linked through
cables, telephone lines, radio waves, satellites, or
infrared light beams.
