1. History of computer

1.1. 0th Generation (1642-1940)

1.1.1. Technology : Mechanical Era

1.1.2. Blaise Pascal, Gottfried von Leibnitz, Charles Babbage, John V.Atanasoff and Clifford Berry

1.2. 1st Generation (1940-1955)

1.2.1. Technology : Vacuum tube

1.2.2. Very costly, huge size, consume lots of electric

1.2.3. ENIAC, EDVAC, IAS Machine, UNIVAC

1.2.4. Technology : Vacuum tube

1.3. 2nd Generation (1955-1965)

1.3.1. Technology : Transistor

1.3.2. Smaller than first generation, consume less electricity than first generation, still very costly, faster than first generation

1.3.3. IBM 7094, CDC 6600

1.4. 3rd Generation (1965-1980)

1.4.1. Technology : Integrated Circuit based

1.4.2. Smaller size, consume lesser electricity, still costly, faster

1.4.3. IBM-360 series

1.5. 4th Generation (1980-present)

1.5.1. Technology : VLSI microprocessor based

1.5.2. Very cheap, use of PC's, very small, portable

1.5.3. DEC 10, PDP 11

1.6. 5th Generation (present-beyond)

1.6.1. Technology : ULSI

1.6.2. Artificial Intelligence, very powerful and compact computers at cheaper rates

1.6.3. Desktop, laptop, notebook

2. Basic Components of the Von Neumann Machine

2.1. Stored Program Concept

2.1.1. Proposed significant improvements over the ENIAC design

2.1.2. EDVAC, IAS

2.2. Von Neuman Architecture

2.2.1. Sequential processing of instructions

2.2.2. Consists of CPU, memory, & I/O system

2.2.3. A central processing unit (CPU); it contains the control unit (CU), arithmetic/logic unit (ALU) and Interface unit

2.2.4. Memory : Short-term storage for CPU calculations, Holds both instructions and data of a computer program Input devices: keyboard, mouse, scanner, punch cards Output devices: monitor, printer, fax machine Storage: Carry signals and power between different components

3. Modern Computer System and Hardware in Brief

3.1. Hardware + Software = Computer

3.2. System - program that operate device

3.3. Application - specialized

3.4. Network - connection to devices that connected together

3.5. Internet - worldwide

4. Type of computer

4.1. Supercomputer - fastest

4.2. Mainframe - small spec still powerful

4.3. Midrange - less powerful than mainframe but more powerful than personal computer

4.4. Personal computer - smaller spec
