Second Generation Computers(1956-1963)

♛Transistors replaced vacuum tubes.

♛High-level programming languages

(COBOL,FORTRAN)

♛Symbolic language.

♛Stored their instructions in their memory.

Third Generation Computers(1964-1971)

♛Silicon Chips

♛Semiconductors

♛Keyboards,Monitor,interfaced with operating system.

♛Run many different applications at one time.

Fourth Generation Computers(1971-present)

♛Microprocessor

♛Intel 4004 chip

♛Central Processing Unit

♛GUIs, mouse handheld devices

♛Thousands of circuits were build onto a single silicon chip.

Fifth Generation Computers

♛AI(Artificial Intelligence)

♛Voice recognition

♛Parallel processing

♛Natural language

♛Robotics

♛Capable pf learning and self-organization.

I've learned that the Generation of Computers will keep on upgrading and upgrading.

he History of Computing

•1623-1662: Blaise Pascal is a French mathematician and a philosopher,he invented the Pascaline in 1642.

•1642: The Pascaline is a single revolution of one wheel would engage gears that turned the wheel one tenth of a revolution to its left.

•1801:Jacquard's Loom(Frenchman Joseph Marie Jacquard(1753-1871)).This is the first significant use of binary automation.

•1793-1871:Charles Babbage envisioned a steam-powered difference engine and then an analytical engine.

•1816-1852:Lady Ada Augusta punched cards could be prepared to instruct Babbage's engine to repeat certain options,she is the first programmer.

•1860-1929:Herman Hollerith denoised a punched-card tabulating machine to speed up the 1890 U.S. census.

•1890:Hollerith's Tabulating Machine used a hand punch to enter data onto cards.

•1874-1956:Thomas Watson Sr. in 1896 Herman Hollerith founded the Sabulating Machine Company. International Business Machine Corporation(IBM)by company president Thomas J. Watson in 1924.

•1920-1950:The Electro-Mechanical Accounting Machine Era a punched-card technology

•1903-1995: Dr.John V. Atanasoff and his ABC(Atanasoff Berry Computer)this is the first electronic digital computer;The ABC.

•1946:The Electronic ENIAC computer(Dr.John W. Mauchly, Presper Eckert Jr.)used vacuum tubes.

•1951:The UNIVAC 1 the first generation of computer.The first commercially variable elctronic digital computer.

•1954:The IBM 650 introduced in 1954,was designed as a logical upgrade to existing punched-card machine.

•1907-1992:"Amazing" Grace Murray Hopper found the first "bug" in a computer-a real one.

•1958:The First Integrated Circuit is a phase-shift oscillator, was invented in 1958 by Jack S. Kilby of Texas Instruments.

•1963:The PDP-8 Minicomputer is the first successful minicomputer by Digital Equipment Corporation.

•1964:The IBM System/360 and The Third Generation of Computers the third generation was characterized by computers built around integrated circuits.

•1964:Basic-More Than a Beginner's Programming Language Dr. Thomas Kurtz  and Dr.John of Dartmouth College developed a programming language that a beginner could learn and use quickly.

•1969: APRANET and Unbindling of Hardware and Software a V.S. Department of Defense's Advanced Research Project Agency(ARPA) sponsorship of a project named ARPANET.

•1975:Microsoft and Bill Gates, Bill Gates and Paul Allen formed Microsoft Corporation.

•1976:The Apple 1 Steve Jobs and  Steve Wozniak along with Ronald G. Wayne formed the Apple computer Company.

•1981:The IBM PC, IBM tossed its hat into the personal computer ring its announcement of the IBM Personal Computer.

•1982:Mitchell Kapor Designs Lotus 1-2-3, in 1982, Kapor founded lotus Development Company.

•1984:The Macintosh and Graphical User Interfaces, Apple computer introduced the Macintosh desktops computer with a very friendly Graphical User Interfaces.

•1985-Present:Microsoft Windows Microsoft introduced Windows,  a GUI for IBM PC-compatible computer in 1985.

•1989:The World Wide Web Berners-Lee and a small team of scientists convinced HTML (the language of the internet), URLs(Internet Addresses), and put up the first server supporting the new world wide web format.

•1993:The Internet Browser, the development in 1993 of the graphical browser mosaic Marc Andersen and his team.

•1996:The Hand Held Computer, the Palm Pilot hand held computer was introduced by Palm Computing Inc.

As a student I learned that the history of computing is updating and updating into a better ones.

Input and Output Devices

Input Device is an input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an i such as a computer or information appliance. Examples of input devices include keyboards,mice,digital camera and joysticks.
Output Device is an output device is any piece of computer  equipment used to communicate the results of data processing carried out by an information  processing ( such as computer) which converts the electronically generated information into human-readable form.Examples of output devices include microphone,webcam,printer,headphone,monitor and speakers.

I've noticed that I've been using the keyboard and the mouse as an input devices while writing this blog on the other hand the monitor plays a role as an output devices.

ICT is Fun

In our lesson I now know that ICT is being used in all places at Home,at Play,at Work,and at School.In our daily life we used it for our entertainment,work,and in studies.In the future I'm sure that many people from now will used all of the technologies.The Advantages and Disadvantages are very useful for us kids,because we now know what should we do and don't.


I will use this lesson to my daily life.This will help me to know how technologies work and how are they use.This can take me to a better future in life.I should use this to gather some information to use some hard to use technologies. I should apply this to my mind to learn more about technologies or sometimes teach my friends with some hard to use technologies.
