INTRODUCTION TO COMPUTER
WINDOWS
Definations of computer:
A programmable machine that accepts input, processes it
according to specified rules or instructions, and produces output.
an electronic device that stores, retrieves, and processes data, and
can be programmed with instructions.
The First Generation: 1946-1958 (The Vacuum Tube Years) ENIAC, the Mark 1, and the IAS computer
The Second Generation: 1959-1964 (The Era of the Transistor) Mainframes
The Third Generation: 1965-1970 (Integrated Circuits - Miniaturizing the Computer)
Mainframes , Minicomputers
The Fourth Generation: 1971-Today (The Microprocessor) Mainframes,Minicomputers, Microcomputers
The Fifth Generation: 2000-Today (Artificial Intelligence) ????
Evolution of Computers
Categories of Computers Personal computers Personal 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.
Minicomputers Computer 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 systems designed 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.
Categories of Computers
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 requires a supercomputer. Other uses of supercomputers include animated graphics, fluid dynamic calculations, nuclear energy research, and petroleum exploration
Categories of Computers
Laptop A laptop computer is 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 a touchpad (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, notebooks or netbooks.
Categories of Computers
Computer System and Programs A computer system consists of hardware and software
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, instruct the computer on how to operate.
INPUT DEVICE
CPU
(CENTRAL PROCESSING UNIT)
OUTPUT DEVICE
STORAGE
Example :
Keyboard, Mouse
Example:
Hardisk,
Disk
Example:
Printer, Speaker
Components of Computers
Computer
Input Device A device that feeds data into a computer, such as a Keyboard,mouse and joystick.
CPU The central processing unit, or CPU, is the part of thencomputer that executes software programs,including the Operating system .Also call the brains of the computer.
Components of Computers
Storage Store the data Two parts of storage: Primary Storage and Secondary Storage
Output Device
Anything that comes out of computer Output devices include Display screens, loudspeakers, and printers.
Components of Computers
CPUs have three basic parts 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 <= less than or equal to
>= greater than or equal to <> not equal
The Control Unit
•directs the flow of information into the CPU and/or memory or storage
controls which instructions the CPU will do next
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 also
known 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 1s
and 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.
Sound Components - A sound card lets a
computer play and record high quality sound.
Componenst of CPU
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.
Parts of Computer Storage
Secondary storage
A storage medium that holds
information until it is deleted or
overwritten.
For example :
Floppy disk
External Hard disk
Pendrive
A network consists of two or more computers that
are 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.
What is Network
i. Local Area Networks (LANs):
The computers are geographically close together
(that is, in the same building).
i. Wide Area Networks (WANs):
The computers are farther apart and are connected
by telephone lines or radio waves.
i. Area Networks (MANs):
A data network designed for a town or city.
Types of Network
Software is the instructions that a
computer uses to do what you ask it
to.
The two types of software are :
i. Operating systems Software
ii. Applications software.
Software
• Used by the computer to accomplish a task.
• What system software does:
•controls the internal function of the computer
•controls other devices connected to the CPU
• Examples:
• DOS . Windows
• Linux . Unix
Operating System Software
A network operating system is a supervisory software program that resides on the server. It controls how the network operates by defining who can use the network and how information and peripherals are shared among users. Examples: •Novell Netware . Microsoft Windows NT
•AppleShare . UNIX/NFS
Network Operating System Software
- Includes programs that do real work for users .
Examples :
Word Processing – Ms Word
database programs – Ms Acces, Foxpro
Spreadsheets - Ms Excel
web browsers – Internet Explorer
graphic design - Autocad
Application Software
