3. The basic working principles of modern computers were given in the 1940s by American scientists John von Neumann, G. Goldstein and A. Beris. These principles were implemented in 1946 in the United States with the creation of a universal computer called ENIAC. This date is considered to be the date of creation of modern computer technology. Since then, computer hardware and technology began to develop rapidly and went through several stages: 5.Computers with electronic lamps. They were mainly used to solve mathematical problems. 6.electronic computers whose element base consists mainly of semiconductors. Electronic lamps were replaced by semiconductor elements - transistors and diodes. Their functional capabilities have increased significantly. 7.Computers based on elemental microelectronics and integrated circuits. The basis of this generation was IBM 360/370. Based on it, EC computers and other electronic computers were created in the former USSR 8. Micro and Mini computers created with large and very large integrated circuit technology.A separate class of this generation is personal computers. Their creation was revolutionary 10.When most people hear the word computer, they think of a personal computer such as a desktop or laptop. However, computers come in many shapes and sizes, and they perform many different functions in our daily lives. When you withdraw cash from an ATM, scan groceries at the store, or use a calculator, you're using a type of computer. 11.Many people use desktop computers at work, home, and school. Desktop computers are designed to be placed on a desk, and they're typically made up of a few different parts, including the computer case, monitor, keyboard, and mouse 12.The second type of computer you may be familiar with is a laptop computer, commonly called a laptop. Laptops are battery-powered computers that are more portable than desktops, allowing you to use them almost anywhere 13.Tablet computers—or tablets—are handheld computers that are even more portable than laptops. Instead of a keyboard and mouse, tablets use a touchsensitive screen for typing and navigation. The iPad is an example of a tablet

2. What is
Computer?
A computer is an electronic device that
manipulates information, or data. It has the ability
to store, retrieve, and process data. You may
already know that you can use a computer
to type documents, send email, play games,
and browse the Web. You can also use it to edit
or create spreadsheets, presentations, and
even videos.

3. The history of
Computers

4. Evolution of Computers
• The First Generation
• The Second Generation
• The Third Generation
• The Fourth Generation

5. First Generation Computers
• 1.Use of vacuum tubes
• 2.Big & Clumsy
• 3.High Electricity Consumption
• 4.Programming in Mechanical Language
• 5. Larger AC were needed
• 6.Lot of electricity failure occured

6. Second Generation Computers
• 1.Transistors were used
• 2.Core Memory was developed
• 3.Faster than first generation computers
• 4.First Operating System was developed
• 5.Programming was in Machine Language
& Assembly Language
• 6.Magnetic taped & discs were used
• 7.Computers become smaller in size than
the First generation computers

7. THIRD GENERATION COMPUTERS
• 1.Integrated circuits developed
• 2.Power consumption was low
• 3.SSI &MSI Techonolgy was used
• 4.Hugh level languages were used

8. FOURTH
GENERATION
COMPUTERS
• LSI & VLSI Technology used
• Development of portable Computers
• RAID Technology of data storage
• Used in virtual reality, multimedia,
simulation
• Computers started in use for Data
Communication

9. The Future
The future promises advanced technology in
computing. Faster, smarter and more
affordable

14. Servers
• A server is a computer that serves up
information to other computers on a network. For
example, whenever you use the Internet, you're
looking at something that's stored on a server.
Many businesses also use local file servers to
store and share files internally.

15. PCs and Macs
• Personal computers come in two
main styles: PC and Mac.
Both are fully functional, but they
have a different look and feel, and
many people prefer one or the other.

16. • This type of computer began with the
original IBM PC that was introduced in 1981.
Other companies began creating similar
computers, which were called IBM PC
Compatible . Today, this is the most common
type of personal computer, and it typically
includes the Microsoft Windows operating
system

17. Macs
• The Macintosh computer was introduced in
1984, and it was the first widely sold personal
computer with a graphical user interface,
or GUI (pronounced gooey). All Macs are
made by one company (Apple), and they
almost always use the Mac OS X operating
system.

18. Introduction
• The basic parts of a desktop computer
are the computer case,
• monitor, keyboard, mouse,
and power cord. Each part plays
an important role whenever you use a
computer.

19. Computer case
• The computer case is the metal and plastic box
that contains the main components of the
computer, including the motherboard, central
processing unit (CPU), and power supply.The front of
the case usually has an On/Off button and one or
more optical drives.
• Computer cases come in different shapes and sizes.
A desktop case lies flat on a desk, and the monitor
usually sits on top of it. A tower case is tall and sits
next to the monitor or on the floor. All-in-
one computers come with the internal components
built into the monitor, which eliminates the need for a
separate case.

20. Monitor
• The monitor works with a video card, located
inside the computer case, to display images
and text on the screen. Most monitors
have control buttons that allow you to
change your monitor's display settings, and
some monitors also have built-in speakers.
• Newer monitors usually have LCD (liquid
crystal display) or LED (light-emitting diode)
displays.These can be made very thin, and
they are often called flat-panel displays.
Older monitors use CRT (cathode ray tube)
displays.CRT monitors are much larger and
heavier, and they take up more desk space.

21. Keyboard
• The keyboard is one of the
main ways to communicate
with a computer.There are
many different types of
keyboards, but most are very
similar and allow you to
accomplish the same basic
tasks.

22. Mouse
• The mouse is another important tool for
communicating with computers. Commonly
known as a pointing device, it lets
you point to objects on the screen, click on
them, and move them.
• There are two main mouse types: optical
and mechanical. The optical mouse uses an
electronic eye to detect movement and is
easier to clean. The mechanical
mouse uses a rolling ball to detect
movement and requires regular cleaning to
work properly.
