Published: Last Edited:

This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

Assumption has been received by the government-funded network of desktop computers specifically to buy 8 and Internet connection, Two interactive whiteboard (I do not need two interactive whiteboard, so I changed to an interactive whiteboard with a Projector), for classroom use, laser printers, and network management schools out of the existing database. I will be in a classroom computer desktop over the previous seven students (about 3 students in a computer), and the ratio of teachers to use computers and interactive whiteboards and laser printer connected to the teacher's computer.

Desktops are interrelated and 8 and connected to the Internet. I 2 software installed computer teacher Database management systems. In the off-the-box software is Microsoft's Visual Basic, it catered to the calculation of System registry, query and payment functions. With the resources and create our plans, we will use SQL Server as the database management system and Microsoft Access will be chosen as, or Database program. However, the Government has specific funding needed to purchase eight desktop computer network and Internet connection, two interactive whiteboard for classroom use, laser printers, and network management schools out of the existing database.

But I assume that all the hardware and software, the government is financial support, all the hardware and software must to find and build their own. I think the hardware and software to find and build directory as follows:

On the Web, we should ensure that each location has an Internet line and power cord to place a computer, so I'm looking for suppliers to meet in the classroom every seat has an Internet Block and Power Block.

I will find on the Internet and computer plaza and build eight computers.

I will find on the Internet and computer Square, and build an interactive whiteboard with a projector.

I will find on the Internet and computer plaza and build a laser printer.

I will find on the Internet and computer plaza and build database management software Microsoft Access.

Search Results

First, in the network, it is necessary to ensure that every location has an Internet line and power cord to place a computer, so I'm looking for suppliers to meet in the classroom every seat has an Internet Block and Power Block. In this Internet lines and power lines, I have worked my way suppliers. The suppliers are often a good price than to me, completed on time and provide a good maintenance. On these points, we always cooperate. This is to find them, take the same course price Similar to other suppliers, but completed on time with a good maintenance work, to my faith than they, so I finally They are looking for e-mail an offer sheet to me.

The second point I will find on the Internet and computer plaza and build eight

Computers. In this eight-part computer, I will face in the Internet and computers

To find two square Comparison of different models to do (one is a tower-type

Computer, a computer is the one molding). As these eight computers are only used for As Internet use, so do not need too good or too new models, so the search began in the price and build. These two Computers are as follows:

Place on the Internet and computers to find and build the results of these two

Computers. I would choose the one forming the computer, back is the chart

3.2b. Because of the price ratio Cheaper, more attractive appearance and

Image to attract students, the simple cable management can avoid the messy

Work space safer One-piece computer tower PC volume less volume, so the

Computer will choose one shape.

The third point I will find on the Internet and computer Square and build two

Interactive whiteboard. Today's classrooms need to be flexible is a set of tools

It can create different teaching past, but also to strengthen student learning

Ability. So I looked online TEAMBOARD An Egan Company's suppliers and

They have an interactive whiteboard are good for our school, See details and Figure 3.2c
