1. Each student to illustrate the computer networks on a daily basis for three
examples and explain in detail below.
-Components of a computer network
-The benefits of networking computers.
-Disadvantages that may arise from the use of the computer network.
Computer networking on a daily basis.
example is 1
Businesses such as shops, department stores. And factories. Computing in
bookkeeping, word processing tasks, and contacts with outside agencies via
telecommunications. The industry. Most computer-aided production control. And a piece of
equipment such as car assembly plants. This makes the production of better-quality
companies can get. Or banks. Leave a withdrawal via ATM automated teller (ATM) and the
computer to charge interest to the depositor. And transfer funds between accounts.
Connected to the network
example is 2
Science, Medicine and Public Health. Can be used in computers used
in the calculations are quite complex, such as the study of chemical molecules.
The orbital path of a rocket into space. Or financial registration statistics, and a
device for the treatment of disease. This will provide more accurate results
than the traditional chemical methods. And treatment more quickly
example is 3
Transport and communication workers. In respect of the travel. To
use the computer to book a seat, which is linked to all stations or all airlines.
Convenient to travelers who do not need to wait. They are also used in control
systems such as traffic lights, traffic signs, and air traffic. Or to communicate it
to the orbit of the satellite to be in orbit. This will affect the signal
Components of a computer network.
Host computer. Means the computer. Acting as a resource (Resources),
including various memory, processor, memory and database backup programs, etc. in
the local area network (LAN) is a computer called a server. The network remotely. Used
mainframe computers or mini-computers as the hub of the network. We call that the
Host Computer and the machines waiting for service or the client workstations.
Communication channel refers to the medium used as a path or
way. To transmit data. The receiver (Receiver) and sender information.
(Transmitter) present a communication channel. For network connection.
There are many different types of computers. Phone line not insulated
twisted pair (UTP) twisted pair cable. With insulated (STP) cable Coaxial al.
Fiber optic Micro Web and satellite radio etc.
Devices in the network.
Network adapter (Network Interface Card: NIC) circuit means for
Used to connect the network cable. Installed on a server computer. And the
client. The function of this card is sent from the computer through the
transducer cable. The computers in the network can exchange information.
Network Interface Card :NIC)
The benefits of networking computers.
Devices sharing (Sharing of peripheral devices), computer network
users. Can use the device. Peripheral connected with computer. Together
effectively. Such as printers, scanners, modems, disk drives, CD-ROM, etc., thus
saving costs. No need to buy expensive equipment. Connecting peripherals to
Sharing of peripheral
Can communicate remotely. (Telecommunication) connections. A network. Both
types of networks, LAN, MAN and WAN makes computer. Can communicate with remote
data exchange by using this application software. The communication. Preferably In
networking for the Internet. There are many different services, such as file transfer. The use
of electronic mail (Electronic Mail), information retrieval (Serach Engine) etc.
LAN , MAN WAN
Electronic Mail) Serach Engine)
It can be applied in the business (Allah Business Applicability) businesses are
linked computer networks. To business interests, such as the network of banking business
aviation insurance. Transport. Securities. Can operate. Quickly. Meet customer satisfaction.
To customers today. Began to take advantage of the Internet network to do business
together. Such an order. Payment through a bank.
Disadvantages of computer networking.
1.Potentially error prone. Since every computer. Subjected to
a single line, so if there is a lack of a certain position. It would make
some machines. Or all of the system does not work as well.
2.Because it is difficult to detect node at any one time. A
single computer only. Can send messages. Out on the line. So if you
have many computers. May cause network congestion. This will slow
down the system.
