2. Info storage and retrieval
Entertainment
Communication as well as accounting
Running software and Calculating
Computers have many uses today,
however the general tasks that
computers are programmed for are
as follows:
3. The Abacus or Counting Frame
• Calculating device used centuries before the written modern
numeral system.
• Is Still widely used by merchants, traders and clerks in Asia
and Africa.
Antikythera
• An ancient analog computer, designed to predict astronomical
positions and eclipses.
• The instrument was designed and constructed by Greek scientists
and has been dated between 150 to 100 BC.
4. First Generation
Computers
• Significantly
slower processing
speeds (.001khz)
• Low amount of
RAM (2 Kbytes)
• Broke down often
due to over
heating
Second
Generation
Computers
Third
Generation
Computers
• Much smaller than
predecessor
• Faster processing
speeds
• Cheaper to buy than
first generation
• More reliable, less
frequent malfunctions
• Increased
processing speed
far beyond any
previous computer
• Networking
efficiency
• Even smaller and
used less energy
5. What Is VisiCalc ? VisiCalc is...
Originally released for the Apple II
The first spreadsheet program
Considered the application that turned the microcomputer from a hobby for
computer enthusiasts into a serious business tool.
6. Also known as personal computers,
these computers whose size,
capabilities and original sale price
make them useful for individuals, and
are intended to be operated directly by
an end-user with no intervening
computer operator.
The World Wide Web is a system of
interlinked hypertext documents that
are accessed via the Internet.
With a web browser, one can view
web pages that may contain text,
images, videos, and other multimedia
and navigate between them via
hyperlinks.
PCs
World Wide
Web
These two subjects intervened
with one another by PCs
gaining access to the WWW in
1994.
7. Multi Media
Convergence
Voice, Data and video devices arte able to share resources and internet with
each other via one platform.
The development of different technological systems to evolve toward
performing similar tasks
Multimedia refers to content that uses a combination of different
content forms.
Multimedia includes a combination of text, audio, still images,
animation, video, or interactivity content forms.
8. The uses of the original computers are still the main
purpose of computers but in this generation computers
have developed many more diverse uses such as:
Entertainment, Automatic construction of mechanics,
Business tools etc.
The next generation of computing seems very
promising. With many new and improved forms of
technology like nanotechnology and the further
development of robotics and AI. I believe our world
will soon evolve completely around the reliance and use
of technology and it will become a huge factor in our
lifestyle .
