LAN Types

Series Local (Local Area Network)
System of a large series (MAN and WAN) is more useful in terms of the breadth of its geographical area but many organizations need the local circuit for connecting devices that are used in place. So the following aspects should be considered:
LAN Type - User and waitress (Client-server)
- User-peer users (peer to peer)
LAN Components
LAN Topology
The impression from the LAN

LAN Types

There are two types of series of Local Area (LAN), namely:

Users and the waiter (Client-server)
LAN type is composed instead of a computer waiter (server) to bring out another computer that acts as the user (Client). Computers waiter will perform the maintenance center (Centralized) to bring out users in terms of partnership in applications, data, printers, etc.. The waiter is usually high in power. Types:
Waiter files (File Server) - Save stuffing and data.
Waiter data (database server) - Save the data simple.
Waiter print (Print server) - guarding one or more of the printer.
Waiter fax (fax server) - arrange delivery fax.
Mel waiter (Mail server) - arrange e-mail.
Usually this waiter does not process or alter the data sent. The waitress did not need to know what kind of fail, instead he was busy responding to requests from the user's computer for files that kept. Examples stuffing Series Operating System / Network Operating System (NOS) is Novell Netware, Windows NT, UNIX

Peer users (peer to peer)
This system does not involve computers clint. He justifies partnership tools and files. Each computer can send, receive and process data files but every computer has the same potential. Examples of NOS is AppleShare and Windos for Workgroups, Windows 95 and Windows 98.

The components for the LAN


Computer waiter (server)
Usually consist instead of a Pentium Celeron 333A system type. 64MB SDRAM, 4GB hard cakera, 15 "digital color monitor, 40X CD-ROM drive, Kad Interface Series (Ethernet Network Card), Kad 8MB SVGA and 16 bit 3D sound KAD

Stasen work (Workstation)
Usually composed than 486 types of systems and above, 16MB RAM, 540MB hard cakera, 15 'color digital monitor, 40X CD-ROM drive, Kad Interface Series (Ethernet Network Card), Kad and KAD 8MB SVGA 16 bit 3D sound.

Network Interface Card / Kad Interface circuit (NIC)
NIC needs to be installed on each computer and connected to a circuit with a cable or infrared rays. Here are some types of NIC.
Ethernet Card-Example: 3Com (RM 350), D-Link (RM 220),

10 Base (RM 120)
Token Ring Card
LocalTalk Connector

Without circuit Wayar (Wireless network)
Without a functioning circuit Wayar using radio frequency or infrared transmission to connect the atnatara one another. The purpose of this series is to ease the user's computer book (notebook), handheld computer (palmtop) and PDA (personal digital assistant) which is engaged in a building. There are three ways to use the circuit without wayar namely The fixed (stationary), Peer to peer and mobile (roaming).

The weakness of this series is high boarding house (3 times more than the double circuit), easily distracted by the radio waves and micro wave, slow and had to find another point to continue the achievements of docking with the LAN if the signal becomes weaker.

Principle is to customize without wayar (Wireless Adapter) and achievement points (access point), the circuit (Novell Netware, LANtastic)

The series Operating System / Network Operating Syatem (NOS)
Operating System Series responsible to top:
Directs data traffic on the circuit.
Justify and block the transfer of data between workstations.
Manageflow of data between different workstations not completed
Managing service demand printer.
Managing requests and orders between the user circuit.
Manage relationship between networks and remote locations.
Examples of NOS is AppleShare and Windos for Workgroups, Windows 95 and Windows 98, Windows NT, Novell Netware and UNIX

Hab (Hub)
Hab used to be central to the series of star (Star). He used to escort traffic flow data and the announcement in the series. Example 8ports Ethernet Hub (RM200), Ethernet Hub16ports (RM400), 10Base8 ports (RM550), 10Base16ports (RM1200)

Bridges and gateways
To connect two or more series of a bridge needs to be provided to interface(interface) to match. When a gateway needs to be used for the different interface vessel and content terms.

Router
Routers are used to translate edict among the circuit apart. Routers know the address of the computer for the second bridge and the two circuit-Logo. Kindness is a router.
attenuate signaling by memorable.
declaration between the two protocols or circuit.
edict among the different LAN topologies.
edict on the type of cable that different.

content application

Content version of the series need to use common and easy series escorted by content circuit. Example content applications, Excel, Lotus 1-2-3, Word, Word Perfect, etc..
