![CLASSIFICATION OF DIGITAL COMPUTERS
Micro-Computer:
Micro-computers are smallest and the least expensive computers. Its works on LSI [Large Scale Integration] and
VLSI [Very Large Scale Integration]. This computer can execute Millions of instructions per second [MISP].
Second Generation(1956-63):
In 2nd generation computers, vacuum tubes were replaced by transistors. This generation computers generated less
heat & were reliable. The first operating system developed in this generation.
Third Generation(1964-71):
3rd generation computers replaced transistors with Integrated circuit known as chip. From Small scale integrated
circuits which had 10 transistors per chip. These computers were smaller, faster & more reliable. High level
languages invented in this generation.
fourth Generation(1972- present):
As a result microprocessors came into existence. The computers using this technology known to be Micro
Computers. High capacity hard disk were invented. There is great development in data communication.
Fifth Generation (Present & Beyond):
Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some
applications, such as voice recognition, that are being used today. The use of parallel processing and
superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and
nanotechnology will radically change the face of computers in years to come.](https://image.slidesharecdn.com/22-thursdat-240226173848-971e1923/85/Computer-Science-Fundaments-of-Computer-6-320.jpg)
Computer Science | Fundaments of Computer
- 1. CHAPTER : 1 FUNDAMENTAL OF COMPUTER Presentation
- 2. WHAT IS COMPUTER? Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations.
- 3. Input (Data): Input is the raw information entered into a computer from the input devices. It is the collection of letters, numbers, images etc. Process: Process is the operation of data as per given instruction. It is totally internal process of the computer system. Output: Output is the processed data given by computer after data processing. Output is also called as Result. We can save these results in the storage devices for the future use.
- 4. Computer System All of the components of a computer system can be summarized with the simple equations. COMPUTER SYSTEM = HARDWARE + SOFTWARE+ USER • Hardware = Internal Devices + Peripheral Devices All physical parts of the computer (or everything that we can touch) are known as Hardware. • Software = Programs Software gives “intelligence” to the computer. • USER = Person, who operates computer.
