How we use computers on LAN in school

In our classroom, we use computers to work and study. All computers are in LAN and are connected with a principal server, which we can get excercises and study stuff from. In each classroom, there is an important computer, the teacher’s computer. On that computer, they can show their screen on the wall to teach us better.

In our school, there is a secretaries’ office. In that room, I think they use the computers to record data on the databases, so the headmaster can get all the information about students thanks to the LAN. So, the headmaster uses his computer to create reports and view information about all of us.

Finally, we use the computers in the library to work quietly.

Description of the LAN

This LAN connects receptionists, doctors, and the practice manager in a health centre. It also connects the centre with the local health board. There's a computer in each consulting room, the doctor use the computer for information about medicines, they also use to connect with other hospitals, they also use PC for email connection to hospitals, other practices, and the local health board. There is a PC in each consulting room and another in the practise manager room and in the reception. There there is also a server and two printers, a laser one and a dot-matrix one.
The receptionits use the PC mainly for appoiments, the doctors use it to get drugs information, to write, to check and to save patients records and for prescriptions.
All of them use the PC for surfing the web and send email to hospital, other practices and the local health board.

Pen drives

Pen drives are very common. You can use it for storing data. They are removable drivers, you can remove them from the computer and carry them wherever you want. So it's so easy carry them because they are so small that you can save in your pocket. Nowadays, they have a large capacity like 8GB and higher. the relation between price/capacity is very acceptable. They are chepeast.

We need a new printer

Jason:
I need to printer with the best quality. The price doesn't matter. What kind of printer should I buy?

- You need a mono laser printer because it's the printer with the highest quality. The price is more expensive than other printers, but it doesn't matter you said.

Claire:
I need to print really fast. I’m not going to use colour or images. Shall I buy an inkjet printer?
- You shouldn't because it's slower than laser printers. You should buy a laser printer because it's faster than an inkjet printer

My favorite mouse

What are they for?

Mouse: This peripheric is used to move the cursor of the screen in the way you want. If you move it up, the cursor goes in the same direction.

Scanner: Using a scanner, you can input printed drawings directly into a computer.

Microphone: A microphone is used for inputting sound in your pc or simply amplyfied.

Joystick: With a similar use like a mouse, It are used in computer games.

Keyboard: Another basic peripheric that allows you to type text and does other things like move inside your OS.

Shuttle - Dell - Acer

These computers are differents from one another. One is better than the others but each computer has nice featurings.
Shuttle is a powerful computer and the best of this computer is that it is the smallest computer. It is as small as "xbox", the famous videoconsole.
But Dell is a computer that has a lot of history and Dell computers are really good. The only problem is that it is not compatible with other computer stuff.
I think Acer computers are better than Shuttle and Dell computers. The company has a lot of stuff for computers and has a good reputation in this world. So I would buy an Acer computer because they are the best and also they're the chepeast.

For example, Dell computers have their own processors while Acer computers can use any processor like Intel or AMD, which are the best processors you can use. But if we compare Acer with Shuttle we can see:

Shuttle:
AMD AM2 and future AM2 multiple core processors
Acer:
AMD Athlon 64 x 2 Double Core 4200

The Shuttle processor is faster than Acer processor whereas Shuttle processors will be the fastest with "multiple core" and Acer has only Double Core.

Talking about price, Acer costs 649€ and Shuttle 599€. In this case, Shuttle is less expensive than Acer, but you have to buy other peripherics like a monitor, etc.
