Endterm Project: What are the steps and ways to build theIntranet at Watcharawittaya English Program School?

      

       people is called in many names such as Campus network, Local internet etc. From the study on an intranet. Also know the benefits of an intranet.Hall connected throughout the country as the creation of information services. Similar to the Internet, which opened almost anything.But only allow access to only people in the organization. To limit the scope of use.And that agencies used to facilitate the agency.So we will divide the application to the school intranet. The documents were sent by walking across the buildings.

Benefits of implementing an intranet application in one unit. Can be summarized as follows.


- The low investment requirements for hardware and software similar to that used in the Internet network to a variety of products and low prices. Thus the cost of network deployment, compared with less. Costs to invest in other systems.

- Intranet network standards. And application as well as Internet. Which are widely available. And through the adoption of popular standards by default. With both hardware and software products to choose various



- Reliable Technology that is through trial and improvement. Until the status of high reliability.- Communication is universal Intranet users can submit news in the form of E-mail is standard among colleagues within the agency and internet users. That outside agencies have.

- Performance data can support data communications that contain text, graphics and sound.

what is an intranet  And how they benefit.

- In fact the installation of Internet server such as WEB server, Mail server etc.

- Computer server requires the network with other machines in the school or organization

- Is another computer to use the same machine as an intranet server.

- To download software can be downloaded at http://www.google.com/ a section Server Daemon freeware or shareware, and then select the installation that you are interested in your server (software that you choose must match the OS you use)

     Installation and came to Home Page, software web server such as freeware or shareware available to do good all the simple Home Page Home Page is a view of others to save source and then bring it out to edit.And this is to install a basic intranet anyone can do.

WHATARE THE THREE BASIC PROGRAMMING CONTROL STRUCTUSE ?

-Beginners can find Programming very confusing, Just like any other subject, there are a lot of new concepts to understand and lots of new terminology to learn. One of the most basic concepts in programming is control structures. There are three control structures and all programmers must learn what they are and how they can be used.These three basic structures can be used to develop any kind of program and they are explained below.

 SEQUENTIAL PROGRAMMING
-The most straightforward control structure is the sequence. A list of what to do, step by step.


Example
1.do the first thing
2.do the next thing
3.do another thing

 IN PSEUDOCODE
- Declare a variable called count
- Set count to 1
- Write out the value of count

 REPETITION IN PROGRAMMING
-Repetition is also called iteration and is used when something is repeated over and over again, so anything where the program goes round in a loop. Typically programmed using code such as WHILE, REPEAT and FOR statements.


Example
1.Do the first thing
2.While (some condition is TRUE)
3.Do b
4.Do c
5.Do the next thing

IN PSEUDOCODE

- Set count to 0

- WHILE (there are items in a pile)
- Increase count by 1
- Write out the number of items
Another example to write out numbers 1 to 10
- FOR count = 1 to 10
- Write out count
- Write out ‘finished’


NOTE: a FOR loop is used when it is known exactly how many times to go round the loop
-Selection in Programming : Making Decisions
-Selection is used to make a decision to go down one path or another, often programmed using code such as an IF statement, or a CASE statement.


Example: To Pack my bag for work
1.Pack my PC

2.Pack my money
3.If it's raining
4.Pack my coat

IN PSEUDOCODE
- Work out total cost
- If (total cost > £10) THEN
- Write out ‘no delivery charge’
- ELSE
- Write out ‘£5 delivery charge’
- Write out ‘thankyou’

Another example using a CASE
- Write out the day
- CASE (day)
- Monday: write out ‘first working day of the week’
- Friday: write out ‘last working day of the week’
- Saturday: write out ‘the first day of the weekend’
- Sunday: write out ‘the second day of the weekend’

ENDCASE

- Sometimes there is confusion between the Repetition and Selection statements, as both use a condition. A condition is a test, resulting in true or false. One way of describing the difference is that when making a selection, the condition is only ever tested once. When used in repetition, the condition is tested a number of times, every time the program decides whether to loop.


- Beginners who take the time to learn the basic building blocks of programming will find coding in new languages easier and developing computer programs requires an understanding of the three basic control structures outlined above.

1.What is a computer network?
-A computer network, often simply referred to as a network, is a collection of computers and devices connected by communications channels that facilitates communications among users and allows users to share resources with other users. Networks may be classified according to a wide variety of characteristics.


2.what are the types of network?
There are two types of networks
-Client/Server Networks
Client/server networks consist of two kinds of computer. The clients are usually computer workstations sitting on the desks of employees in an organisation. The servers are usually more powerful computers and are held in a central location or locations within an organisation.

-Peer-to-peer Networks
Peer-to-peer networks have workstations connected to each other but do not have servers.
Files can be shared between workstations, and a printer connected to one workstation can be accessed by another workstation.
Peer-to peer networks are often much simpler to set up than client/server networks. However, they lack some of the advantages normally associated with networks such as centrally managed security and ease of backing up files.
Peer-to-peer networks would really only be set up among a few computers within an office or single room.

What is Intranet?



Answer. An intranet is a private computer network that uses Internet Protocol technologies to securely share any part of an organization's information or network operating system within that organization. The term is used in contrast to internet, a network between organizations, and instead refers to a network within an organization. Sometimes the term refers only to the organization's internal website, but may be a more extensive part of the organization's information technology infrastructure. It may host multiple private websites and constitute an important component and focal point of internal communication and collaboration.






What are the advantages of having School Intranet?


Answer. 1. Assist in the search to find work.


2. Make the news more quickly and easier.

3. To the new knowledge.

4. A system of teaching through the Internet.

5.We search the Internet easily and quickly


6.We search the Internet don't waste the time

7.it's easy to contact another office .
