 3 rd Generation 
- Usage of integrated circuits. 
- A single IC has many transistors, resistors and capacitors along with the associated circuitry. 
- Able to build smaller, faster and cheaper computers. 
- could run multiple programs for multiple users at the same time (multitasking).
 - Keyboards and monitors developed during the period of third generation of computers. 
- Operating Systems were introduced 

 4 th Generation
 - Large-scale and very large-scale integrated circuits
 - Microprocessors that contained memory, logic, and control circuits on a single chip.
 - Allowed home used personal computers.

 1. 1 st Generation - ENIAC - ENIAC - Electronic Numerical Integrator And Computer 
- Developed to help with the calculation of the trajectory table for WW2. 
. - Characteristics: 
- Uses vacuum tubes\- Programmed manually using switches.
 - Uses decimal numbers. -
 Uses 20 accumulators. -
 Weight 30 tons and requires huge space
- Can do 5000 additions per second
. - Too late to be used for WW2, but then it was used to test the hydrogen bomb 

 2 nd Generation 
- Usage of transistors. 
- Replaced the vacuum tubes.
 - More complex arithmetic and logic units and control units. 
-smaller and cheaper
-lets out lesser heat compared to vacuum tubes.
 - Start using magnetic tapes to replace punched cards to store and retrieve data.
 - Start using high level programming languages such as COBOL and FORTRAN. 
- Started the “mini” phenomenon that sees the building of smaller computers especially in the 3rd generation.
 - Ability to load data, move data (peripherals/libraries) and perform more complex computations. ]]> 2018-08-14 08:08:48 UTC https://padlet.com/nurainmohamad_mmu/2372td2ppxdn/wish/273015500 Convert 88A9D.4B5C to binary equivalent https://padlet.com/nurainmohamad_mmu/2372td2ppxdn/wish/273015748

The ALU is a part of the computer that actually performs arithmetic and logical operations on data.
The other elements of the computer system are mainly to bring data into the ALU for it to process and then to take the results back out.
They based on the use of simple digital logic devices that can store binary digits and perform simple Boolean logic operations.]]> 2018-08-14 08:22:31 UTC https://padlet.com/nurainmohamad_mmu/2372td2ppxdn/wish/273016761 Question 1.

What does Mnemonic mean?

A mnemonic is a term, symbol or name used to define or specify a computing function. Mnemonics are used in computing to provide users with a means to quickly access a function, service or process, bypassing the actual more lengthy method used to perform or achieve it. Assembly language also uses a mnemonic to represent machine operation, or opcode.


Explains of Mnemonic

In computer programming, routine programming functions are assigned a mnemonic that is shorter in length but provides the same functionality as the original function. 

In assembly language, mnemonics are used to specify an opcode that represents a complete and operational machine language instruction. This is later translated by the assembler to generate the object code. For example, the mnemonic MOV is used in assembly language for copying and moving data between registers and memory locations

 What are the factors contributing to the replacement of vacuum tubes by transistors? 

Answer: Vacuum Tubes: Advantages

  1. Superior sound quality.
  2. Highly linear without negative feedback, especially small-signal types.
  3. Smooth clipping is widely considered more musical than transistors.

Transistors: Advantages

  1. Usually lower cost and smaller than tubes, especially in small-signal circuits.
  2. Can be combined in the millions on one cheap die to make an integrated circuit, whereas tubes are limited to at most three functional units per glass bulb.
  3. Lower power consumption, less waste heat, and high efficiency than equivalent tubes, especially in small-signal circuits.
