A Server Maintenance and setting

Beside thinnet and Thicknet, there are Types of Wiring can be used

 

- Twisted Pair Ethernet

 

Twisted Pair cable is divided into two types of shielded and unshielded. Shielded cable is a type that has a sheath wrapping while unshielded sheath has no wrapper. For this type of connection cable uses an RJ-11 or RJ-45.

In twisted pair (10 BaseT) network, a computer arranged to form a star pattern. Every PC has one twisted pair cables are centralized at the HUB. Twisted pair is generally more reliable (reliable) than the thin coax because HUB have error correction capabilities and enhance data transmission speed. Currently there are several grades, or categories of twisted pair cable. Category 5 is the most reliable and has high compatibility, and the most recommended, went well at 10Mbps and Fast Ethernet (100Mbps). Category 5 cable can be made straight-through or crossed.

 

Straight-through cable used to connect computers to the hub. Crossed cables are used to connect the HUB to HUB. The maximum length of cable Twisted-Pair cable is 100 m.

 

- Fiber Optic

A network using Fiber Optic (FOR) are usually large companies, due to price and installation process more difficult. However, networks that use FOs in terms of reliability and speed is not in doubt. Data transmission speeds with more than 100Mbps FO media and free environmental influences.

When viewed from the server’s role in both types of networks, then the server on the network type of peer to peer termed non-dedicated server, because the server does not act as a pure server but at the same time can serve as a workstation.

Excellence

1. Between computers in a network can share mutually owned facilities such as: hard disk, drive, fax / modems, printers.

 

2. Operational costs are relatively cheaper compared with the type of client-server network, either because they do not require a server that has a special ability to organize and provide network facilities.

 

3. Continuity of employment is not dependent on a single network server. So that if one computer / peer dead or damaged, the whole network will not experience interference.

 

Weakness

1. Troubleshooting the network is relatively more difficult, because the type of peer to peer network each computer it is possible to engage in communication that exist. In client-server network, the communication is between the server and workstations.

 

2. Lower performance compared to client-server network, because every computer / peer besides having to manage the use of network facilities must also manage the work or the application itself.

 

3. Network security system is determined by each user to manage the security of each facility owned.

 

4. Because data is spread across the network each computer in the network, then the backup must be performed by each computer.

 

There are several types of commonly used and cabling can be used to apply Windows, namely:

 

- Thin Ethernet (thinnet)

 

Thin Ethernet or thinnet have advantages in terms of cost is relatively cheaper compared to other types of wiring and the installation of components easier. The length of thin cable coaxial/RG-58 between 0.5 – 185 m and a maximum of 30 computers connected.

 

- Thick Ethernet (Thicknet)

With a thick Ethernet or thicknet, the number of computers that can be connected in the network will be more numerous and the distance between computers can be enlarged, but the cost of procurement is more expensive wiring and installation is relatively more difficult compared with thinnet. In Thicknet transceiver used to connect each computer to the network system and connectors used are type DIX connector. The maximum transceiver cable length 50 m, Thick Ethernet cable length maximum of 500 m with a maximum 100 transceiver connected.

 

There are also Twisted Pair Ethernet and Fiber Optic which will be described on the other page of this website.
