By: Chris Im 1. A network consists of two or more computers that are linked in order to share resources such as printers and CD-ROMs, exchange files, or allow electronic communication. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. 2.
LAN- Stands for local area network. This is usually confined to a small space such as a school, building, home, or a lab. In a typical LAN configuration, one computer is designated as the server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. MAN- Stands for metropolitan are network. This will cover a larger area such as cities or school districts.
By interconnecting smaller networks within a large geographic range information is easily transmitted through the MAN. WAN- Stands for wide area network. This is used to connect larger spans of area like the US, Ontario, or the world. An excellent example of a WAN would be the Internet. A WAN is complicated. It uses multiplexers to connect local and metropolitan networks to global communication networks.
3. As stated above, the range that each type of networks covers is the biggest difference. The LAN is used for small areas, the MAN for cities, and WAN for the world. As the letters increase (L M W), as does the space it is able to cover. Advantages Disadvantages WAN • Covers the most ground • Communicate with more people around the globe • Will not appear much different than other two networks • Has a cool name • Too large to track • Connection problems • Purchase a provider • Complicated setup 5. A NOS stands for! (R) Network Operating System! .
The Essay on Network Card Click Windows Computer
If you want to add additional computers to your network in the future, all you need are more Network Interface Cards and 10 BaseT cables. Simply plug the new network cards (s) into your computer an run a cable form the card to one of the hub's open ports. For even greater expandability, the hub can be joined, or up linked, to other hubs. If you look closely at the front of the hub, you will see a ...
A NOS coordinates the activities of multiple computers across a network. The NOS acts as a director to keep the network running smoothly. The two major types of network OSs are! (R) Peer-to-peer! and! (R) Cline/Server! . 6.
Peer-to-Peer: two advantages are that there is less initial expense. Also, there is less need for setup. For example, an OS such as Windows 95 may only have to be reconfigured to be used for peer-to-peer operations. Disadvantages would be that it is decentralized. Meaning that there is no central repository for files and applications. Another disadvantage is that it does not provide the security available on a client / server network.
Client/Server: Two advantages would be that it is centralized and therefore resources and data security are controlled through the server. Another advantage is that there is flexibility. This means that new technology can easily be integrated into the system. The first disadvantage is that it requires initial investment in dedicated server. Another disadvantage is that that large networks will require a staff to ensure efficient operation. This comes under the maintenance section.
Advantages Disadvantages Peer-to-peer Less initial expense – no need for a dedicated server. Setup – an OS (like Windows 95) already in place may only need to be reconfigured for peer-to-peer operations. Decentralized- no central repository for files and applications. Security – Does not provide the security available on a client / server network. Client / server Centralized – resources and data security are controlled through the server.
Scalability – any or all elements can be replaced individually as needs increase. Flexibility – new technology can be easily integrated into the system. Interoperability – all components work together. Accessibility – server can be accessed remotely and across multiple platforms Expense – requires initial investment in dedicated server. Maintenance – Large networks will require a staff to ensure efficient operation. Dependence – when the server goes down, operations will cease across the network..
