The file server is the heart of all series

The file server is the heart of all series. He is computer speed and contain adequate amounts of RAM and a large store room in addition to the rate interface KAD. Operating system software is stored in this computer. Besides, all applications and data files are also stored here.

File servers escort edict relationship between the Nod in the series. For example, the computer will be escorted if we deliver to a single word processors setesen other work, receiving database files from stesen other work orders and store email in the same period. This causes us to need a computer that can store a lot of notice and may with another in a short.

Among the characteristics that need to exist in the file server is:
the rate of micro-processors (eg Pentium)
disk hard that the rate of at least four gigabytes
RAM at least 32 MB
KAD between the rate of advance
additional slot that many
tape unit endorsement (tape back-ups)
RAID (Redundant Array of Inexpensive Disks) to protect data when valid data eror

All computers are concatenated with the file server are called workstations. All computer workstations contain adequate KAD interface series, stuffing circuit and the appropriate cable. Workstations do not need hyper hyper disc cakera leathery or hard because the fail-files may be stored in a file server. Most computers can function as stesen work.
Network Interface Cards - Kad Between Front Series

Network Interface Cards (NIC) is the physical connection between the circuit with stesen computer work. Most NICs are included in the computer at one additional slot. NIC is a determinant for the top speed something series. It is better to use the NIC that the rate used to follow the type series.

Ethernet Cards

Kad was purchased apart. He may be connected with sepaksi cable (coaxial), twisted pair or fiber optics. Depending on the type of connections and ports namely BNC or RJ45 connections. KAD partly contain adequate Ethernet AUI connector. He may be used for cable, couples distracted and gentian to KAD Ethernet fiber. If this fintion used the tool 'transceiver' need to be connected to the stesen work.


Concentrators / Hubs - Leverage

Leverage is a concentrator or connection devices for all serial cables between stesen work, waiter and stuffing. In a star topology, distracted pair cable used to connect with stesen employment and leverage. Hub also is the leverage they are many slots. With the hub we can put a lot of numbers that follow a series Size desired. Half leverage is passive, namely to justify the switching signal from the computer to other computers without any changes. Active leverage will raise alerts when through it from one device to another device. Active concentrator is used as a repeater if you want to separate circuit. The characteristics of leverage are: is based on port 8, 12, or 24 RJ45
used in star or ring topology stringed star (star-wired ring)
sold together stuffing to arrange port
called also as a hub
habit is loaded in a metal box so that may be included along with the internet modem, bridges and routers
