TOPIC 1: Data, Information and Information Management

Asalamualaikum everyboday and my good lecturer.

Explain the different between Data and Information

Data is raw ,in organized facts that need to be processed. Date can be something simple and seemingly random and useless until it is organized.

For example: Statistics, numbers, characters, images, videos and so on that that get from internet, camera, pendrive, memory cards and so on..

Information is interpreted data. When data is processed, organized, structure or presented in a given context so as to make it useful and have meaningful.

For example, my lecturer name is Miss Nisha. This sentence is have meaningful that make you all can understand, it calls information.

On week 2 we learnt more about information management. Our lecturer explain what is information management and so on.

Next we continue our lesson base on common information management problems. It has some problem such as:

• Large number pf disparate information management systems.
• Little integration or coordination between information systems
• Range of legacy system requiring upgrading or replacement.
• etc

After finish this topic we continue with introduction about computer.

What is the Computer?

 Computer is a programmable machine. This means it can execute a programmed list of instructions and respond to new instructions that it is given.

We can use computer to do our works. Such as, we can use it for typing, edit or design picture or photos, counting and all of things more that we can use it to.

Basic operation that a Compute can perform

- Input

- Processing

- Output

- Storage and another one is communication 

              

The first one, you input the data into the computer. Then, the computer will be processed those Data. when all the data have already processed and have meaningful it will become to information.

example: you input your photos which have in your memory card into computer. then, that photo will be processed by using any program that have in the computer, such as, photo shops and so on. finally, when you output by print out your that photo, it calls information.

EVOLUTION OF COMPUTER

There fifth evolution of computer

The first

Evolution of Computer

1. First Generation( 1949-1950): Vaccum tube

- at that time there were electronic computer: ENIAC(1945) 

- electronic Numerical integrator and computers. and maybe around 18000 vaccum tubes were used to build ENIAC and it was programmed by manually setting swiches.

• that electronic computer were used by US army to calculate and designed hydrogen Bomb. 

2. Second generation (1950 to 1964) Transistors.

- william shockley, john Bardeen and walter brattain who invent the Transistor. and vaccum tubes have been replaced by transistors at that time.

• the most computer was IBM 1401. and it used in high level languages( Cobol: for all common business- oriented language and for translate.

3. The third generation ( 1946-1974) Intergrated circuits (IC)

 many years later, the technology more developed and user started use OS, keyboard and 

monitor.

4. Fourth generation( 1974 to present) VLST/ ULST.

fourth generation was the time that computers are the modern computers.

 It took only 55 years for the 4 generations to evolve. The growth of the computer industry developed technologies of computer inventions. There are many types of computer models such as: Apple Macintosh Dell IBM Ace. Then in 1971, Intel created the first microprocessor. 

1976, Steve Jobs built the first Apple computer. Then, in 1981, IBM introduces its first personal computer. During the fourth generations hardware technology such as silicone chips, microprocessor and storage devices were invented. A microprocessor specialized chip which is developed for computer memory and logic. The microprocessor is a large scale integrated circuit which contained thousands of transistor The transistor on this chip are capable of performing all of the function of a computer’s central processing unit.

 Fifth generation( Now and the future)

• Based on artificail intelligence-computers can think, reason and learn.
• Primary means of input-voice and touch

CATEGORIES OF COMPUTERS

 
•  there are six categories based on size , capability and price

1.  Embedded computers
2.  Mobile devices/computers
3. personal computers
4. Midrange servers
5. Mainframes
6. supercomputers

•  Advantages Computers became 100 times smaller than ENIAC Gain in speed, reliability and storage capacity Personal and software industry boomed

Integrated circuits( Microchip)

- VLSI= very large-scale integration

- ULSI= ultra large scale integration

ensured that Millions of components could be fit into a small chip.

last Monday my lecturer have given some exercises for each group and she asked us to set in group for discuss and answer all the question that i have been given. And what that I can understand about

 IMS, DIS..

INFORMATION MANAGEMENT

•  Information management(IM) is general terms that refers to managing any kind of information.
• It is the collection and management of information from one or more source and the distribution of that information to one or more audiences

• Here are six terms of technology information management encompasses systems. Such as,

1. Web content management(CM)
2. Document management (DM)
3. Records management(RM)
4. Digital asset management(DAM)
5. Learning management systems(LM)
6. Learning content management systems(LCM)
