LETS Start!!!!!!!!!!!!!!!!!!!!!!!!!

4. Let enlist our objectives
• Understanding/sharing the basics of ICT
• Exploring the role/importance of ICT in society
• Explanation and examples of ICT
• ICT in Learning and Teaching
• Description of history and developments of
Computer
• Distinguish different generations
• Classification of computers
• General terms/parts of computer

5. Have you ever used ICT?
• Have you not made a call ever on Cell phone?
• Have you not send an IM using your Cell phone?
• Have you not used Internet/email before?
• Have you not listend Radio ever?
• Have you net watched TV ever?
• Have you never used any computer ever?
• Yes, Of course everyone of you do it daily, I am
sure.
• This is all about ICT…………

6. ICT introduction
• Information: referred as processed form of
data which can be recorded, organized and
transmitted.
• Communication: Transfer of ideas(data &
information) though systems, devices such as
computer, cell phones, internet, TV etc.
• Technology: the way one make, modify and use
tools, techniques, systems and machines to solve
problems efficiently.

8. Basic concepts of ICT
• Comprises of different communication
devices
• Continuously evolving products and services
• Manufacturing of ICT- Equipment
• Variety of services like Software development
and Apps
• Global Village : easy communication and
sharing of ideas
• Refers to those technologies that provide access
to information by means of telecom.

9. Major mediums of ICT (Application)
• Internet and Computer
▫ Web, email, video conference, Social media
▫ Converting seminar into webinars, universities
into Virtual universities
▫ online education, e-business, e leaning, e
commerce
• Cell phones
▫ Calling, IM, communication, games,
entertainment
▫ Mobile Apps

10. Examples of ICT application
• FB groups for communication and sharing
• Whatsapp Groups for quick and multimedia
messaging
• Skype for calling and online lectures and
education by group calls
• Teamviewer for remote access
• YouTube for gigantic source of information in
video format
• Mobile apps and software for routine tasks like
word processing, spreadsheet, and presentations

11. ICT in Teaching and Learning
• Lets try to enlist the benefits of using ICT in
teaching and learning….
• Do you agree that we can teach well?
• Do you agree that students can learn well?
• Do you thing one can present well?
• Do you agree one can work efficiently?
• Then why?
• We why we hesitate to use it?

12. ICT in Teaching and Learning
• Provide new and easy of learning and generating
new ideas. (growing age at school)
▫ The late Arfa Karim (youngest MCP)
▫ Muhammad Ammar Afzal From Okara (highest socre
in ORACLE)
▫ Sumal Hassan form Karachi: 3rd highest earning
eSports professional with total earnings
of$2,401,426.34 .
• Multimedia and other ICT facilities may help
teachers in classroom
• eTesing software can reduce the burden of teachers
• ICT can create effective learning environment

13. Any question about ICT and teaching
and learning via ICT

14. Lets start again with a puzzle
• Guess what machine we are going to find?
• Few tips about that are
• "Giant Brain"
• cost was about $487,000, equivalent to
$6,740,000 in 2016
• It weighed more than 30 tons
• Size was (8 × 3 × 100 feet) in size, occupied
167 m2 (1,800 ft2)
• It consumed 150 kW of electricity.

15. Lets start again with a puzzle: An
Earliest Computer

16. History and development of
Computer
• The base rule is same “necessity is the mother of
invention”
• Abacus Machine
• Napier’s bones
• Blaise Pascal (Pascline- 8 digit)
• Charles Babbage
▫ Difference engine
▫ Analytical engine
• IBM, ENIAC, EDSAC etc mechanical, electro-
mechanical and electrical/digital

17. Generation of Computers
• A step in computer technology is called
generation.
• Development of computers are divided into five
periods called generations
• First
• Second
• Third
• Fourth
• Fifth

18. Generations of computer
Gene Period Technology Features Limitations
First 1951-58 Vacuum tube First electrical
Punch card input
Machine language
Spacious, heat
generated and huge
energy consumption
Second 1959-64 Transistor Punch card input
Magnetic tape storage
High level language
Reliable, speedy, less heat
and less space
AC was required
Complex production
of Transistors
Third 1965-70 Integrated
circuit (IC)—
1000s of
transistors
Keyboard input
Monitor display
High level language
Reliable, speedy, less size
and cheaper
Still IC tech was
complex and
immature, AC was
required

19. Generations of computer
Gene Period Technology Features Limitations
Fourth 1980 Microprocessors
VLSI
ULSI
Millions of
transistors in
single chip
Keyboard input
Monitor display
High level language
Commercial use
Cheaper
No AC required
No senses
Fifth Late
1990s
Artificial
intelligence…
Thinking,
feeling and
reasoning
power.
Voice recognition
Image processing
Optical fiber
communication
PROLOG is language

20. Generations of computer- Fifth
Generation examples (AI)
• Lets try to collect examples from our daily life..
• Robotics
• Mobile sensors
• Sensors used in sanitary items
• Thermostatic used in Refrigerators.
• Gluco-meter
• ICU – monitors
• Modern daily life gadgets.
• Expert systems….

21. Classification of Computers
• On the basis of size, memory and processing power
computers are classified into two major categories
• Size
▫ Super computers
▫ Mainframe computers
▫ Mini computers
▫ Micro computers
▫ Handheld computers
▫ Laptops
▫ Palmtop and PDA

22. Classification of Computers
• Purpose
• Digital computers
▫ General purpose
▫ Digits and characters
▫ Examples are PC, laptop etc
• Analog computers
▫ Special purpose
▫ Continuous type of data rather than digits
▫ Measuring temp, wheel balancing, speedometer
• Hybrid computers
▫ Both digital and analog
▫ Digital sugar checking device, DSL modems

23. Applications of computers
• It is useful in every aspect of life
• Education ( CAL, CBT, e-learning)
• Business (ERP, Info. system, e commerce, )
• Banking (ATM, online banking, m banking)
• Defense (GPS, missiles, nuclear weapons etc)
• Entertainment ( movies, games, music, 3D/HD)
• Health (ICU monitors, HMS)
• Agriculture ( drone monitoring, drone spraying
tools, modern agri machinery)

24. General terms
• Buses : electrical paths though which data and
instructions are transferred (32 bit, 64 bit)
▫ Control bus
▫ Data bus
▫ Address bus
• Computer ports
▫ Serial port
▫ Parallel port
▫ Universal serial bus (USB)

25. General terms
• Buses : electrical paths though which data and
instructions are transferred
• Memory
▫ Primary
 RAM
 DRAM (Dynamic RAM) (refreshed every few
milliseconds) (slow)
 SRAM (Static RAM) fast, used as cache, in smart devices
 ROM
▫ Secondary memory
 Magnetic tape
 Hard disk
 Optical disk (CD, DVD, Blue Ray)

26. CPU (central processing unit)
• Commonly knows as processor…bookname
microprocessor
• Brain of computer
• Intel, Motorola
• Arithmetic and logical unit
• Control unit
• Modern age processor
• Bus interface unit, floating point units, multi
cores processor

27. What we try to learn today?
• What is ICT
• Use of ICT in education
• What is Computer history
• Application of Computer
• What are generations
• What are classifications
• What are general terms
• What is CPU
