Les's we read !
ICT is the technology required for information processing , in particular , the use of computers , communication devices and software application to convert , store , protect , process , transmit , and retrieve information from anywhere at anytime .
First generation ( 1940 - 1956 ) : Vacuum Tubes .
- The first computers used vacuum tubes for circuitry and machine drums for memory .
- They were very expensive to operate and in addition to using a great deal of electricity , generated a lot of heat , which was often the cause of malfunctions .
- The UNIVAC and ENIAC computers are examples of first-generation computing .
Second generation ( 1956 - 1963 ) : Transistors .
- Transistors replaced vacuum tubes and ushered in the second generation of computers .
- The transistor allowing computers to become samller , faster , cheaper , more energy-efficient .
Third generation ( 1964 - 1971 ) : Integrated Circuits .
- Users interacted with third generation computers through keyboards and monitors and interfaced with an operating system , which allowed the device to run many different application at one time with a central program that monitored the memory .
Fourth generation ( 1971 - Present ) : Microprocessors .
- The microprocessor brought the fourth generation of computers , as thousands of integrated circuits were built onto a single silicon chip .
- The Intel 4004 chip , developed in 1971 , located all the components of the computer .
- In 1981 IBM introduced its first computer for the home user , and in 1984 Apple introduced the Macintosh .
Fifth generation ( Present and Beyond ) Artificial intelligence .
- Fifth generation computing devices , based on artificial intelligence , are still in development , though there are some application , such as voice recognition that are being used today .
- Fifth generation computing is to develop devices that respond to natural language input .
Assalamualaikum and hello friends thank you for using my skins. Do you like it? no hurm so you can go away. But if you like and use my skins please friends do not remove credits and take my code if you taking you will die. I know my own code and i can find people who take my code. So please no basecode anymore.
