DEFINE INFORMATION AND COMMUNICATION TECHNOLOGY

EVOLUTION OF COMPUTERS

 ICT

(Information and Communications Technology) is an umbrella term that includes any communication device or application, encompassing: radio, television, cellular phones, computer and network hardware and software, satellite systems and so on, as well as the various services and applications associated with them, such as videoconferencing and distance learning.

FIRST GENERATION SECOND GENERATION THIRD GENERATION FOURTH GENERATION FIFTH GENERATION

FIRST GENERATION  The

first generation of computers is said by some to have started in 1946 with ENIAC.  Computers were built with vacuum tubeselectronic tubes that were made of glass and were about size of light bulbs.

FIRST GENERATION  Use

of electronic valve ( vacuum tubes).  Need to store the instructions to manipulate data in the computer along with the data.

SECOND GENERATION  This

generation begin with the first computers built with transistor.  The transistor replaced the large, cumbersome vacuum tube in televisions, radios and computers.

SECOND GENERATION  Built

with transistor  Transistor led are much smaller and faster.  Use less power and create less heat than vacuum tubes.  More reliable and more energy-efficient than their predecessors.

THIRD GENERATION  The

third generation brought huge gains in computational power.  Computer manufactures began replacing transistor with integrated circuits.

THIRD GENERATION Built

with integrated circuit (is a complete electronic circuit on small chip mode of silicon). More reliable and compact. They cost less to manufacturer.

FOURTH GENERATION  The

fourth generation of computer systems use of large scale integration (LSI - 1000 devices per chip) and very large scale integration (VLSI 100,000 devices per chip) in the construction of computing elements.

FOURTH GENERATION  Built

with chips that used large scale integration (LSI).  Processors will fit onto a single chip.  Use a single chip to create a smaller personal computer.

FIFTH GENERATION  The

fifth generation saw the introduction of machines with hundreds of processors that could all be working on different parts of a single program.

FIFTH GENERATION Increasing

use of single-user workstations. A few processors sharing jobs.
