Cost
is an electronic device that designed to process data. Converting it to information that is useful to people
Computer
Two kinds of Computer
Analog Computer
Digital Computer
Represent data as variable points along a continuous spectrum of values
Analog Computer
Break all types of information into tiny units, and use numbers to represent those pieces of information
Digital Computers
4 Basic Computing Periods - Ages
Premechanical - 3000BC and 1450AD
Mechanical - 1450 and 1840
Electromechanical - 1840 and 1940
Electronic - 1940 and Present
Generations of Computer : (Ages)
1st Generation (1946-1958)
2nd Generation (1959 - 1964)
3rd Generation (1965 - 1970)
4th Generation (1971 - today)
5th Generation (Today - Future)
First generation computers relied on machine language, the lowest-level programming language understood
by computers, to perform operations, and they could only solve one problem at a time. Examples: ENIAC, EDSAC, UNIVAC I
Vacuum Tubes
- Moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers
to specify instructions in words.
Examples: UNIVAC III, RCA 501, Philco Transact S-2000
Transistors
- It could carry out instructions in billionths of a second. Much smaller and cheaper compare to the second
generation computers.
Integrated Circuits
Small computers became more powerful that they could be linked together to form networks, which
eventually led to the development of the Internet.
Microprocessors
The use of parallel processing and superconductors is helping to make artificial intelligence a reality.
Artificial Intelligence
is the largest computer network in the world that connects billions of computer user.
The Internet or “Net” (network of network)
is a collection of computers and devices connected via communication channels and transmission media allow to share resources (hardware, software, data, information)
