What Do You know about computer ?

I am sure everyone know about computer. But everyone has different opinion about that. Some people say that computer is entertainment tool, another people say that computer is sophisticated product and the others people say that computer is something useful which can apply their mind into program.

So..

What’s the meaning about computer.

Introduction of computer

The phrase of “ computer “ come from “computare” which has mean to calculate.

Computer can be mean is an arrangement of electronic media which has function :

1. To Receive (input)

2. To Process

3. To Make a Result (output)

4. To Save The Result (storage)

Input : Data or Digital instruction

Process : Be done as electronic (Electronic Data Processing)

Storage : to save the result of process in memory

Output : Can be look on the output device

The Component of Computer

1. Hardware

2. Software

How to take Computer Business

Do you want to know, how can we do this business,

Think this business Business is a simple yhink and you can do it.
Don't think it's a difficult, if you think it is so hard to do,
I am sure you're really can't do this business.
You are has a special potention
I believe you can do it

How to choose the best specification

The Specification of processor

Processor is one of component which has function to process data to be information,

In Processor , surely you know about clock speed . it calculate in Mega Hertz or Giga Hertz. One hertz is one cycle / s. If Processor has clock speed 3 GHz, it’s mean it has 3 bilion cycle/s.

Kind of computer

Personal Computer

Personal computer is a kind of computer which commonly be used just for one user when the same time.

The kind of this computer for the example

1. Desktop Computer

2. Laptop (notebook)

3. Handheld Computer

Server Computer

Kind of computer which special for multi user. This computer has some ports which can be used together by the users. This computer has bigger size than desktop computer . Server computer be used for network and internet.

Workstation

Workstation is desktop computer which used for High level . Workstation is kind of computer which use single user. It’s mean being used by one person, just only one person at the same time. Workstation has higher potention than PC (personal computer)

Mainframe

Mainframe is multiuser computer . This computer has function for serve a lot of user in use program or take data. The size of this computer so big.

E-Retailing

Retailing is one of the more visible market sector of e-commerce . In retail, merchants sell product and service directly to a buyer . E-retail, also called e-tail, occurs when retailers use the web to sell their products and services.

Enterprise have adopted e-retail as new way to reach customer . E-retailers constantly are challenging the old ways of conducting business as they bring new product and services to market. All e-retailers , however, operate in similar way. Figure 14-24 shows an example of how an-retail transaction might occur.

E-Commerce

Several market sectors have taken advantage of business opportunities on the Web .The more popular market segment include retail , finance, travel, entertainment, and media, and health . The following paragraphs describe how general public interacts which each of this types of enterprises on the Web.

Document management system

A Document management system allow for storage and management of a company’s documents, such as word processing document , presentation and spredsheets. A central library or repository , stores all document within a company or department . the system support access control, security, version tracking of documents search capabilities and the ability of users to check in check out document, Users are granted access to certain parts of repository depending on their needs.

A document management system has benefit of tracking a document through out it’s life a cycle, from creation, through changes, and finally to archival. Additional information can be stored along with the document that describes the uses and history of the document. This information can include the document’s creation date, the user who created the document, the project to which the document belong s, copy right information , a summary of the document , and any keyword associate with the document. This information can be used for searches within the document repository.
