·         Server

·         Workstation

·         Network Interface Card (NIC)

·         Hub / konsentrator

·         Switch

·         Wireless Access Point (WAP)

·         Bridge

·         Repeater

·         Router

1.      Server

Server is one equipment most importantly of network, server in a general way usually constitute high-speed computer with stored capacity (RAM) one that big, that computer that beroprasi can continually.

2.      Workstain

All computer which most link goes to server on one network called by workstain, workstain constitutes default computer that at configuration utilizes network card.

3.      Network Interface card

Network Interface card is constitute equipment that enable its happening relationship among network with workstain's computer or network with server computer. In a general way Network Interface Card constitute internal equipment.

There is Network Interface Card even that frequent being utilized deep network:

·         Token Ring's card

·         Local's card Talc is

·         Ethernet's card, and

·         WLAN'S card

·          

4.      Hub / Konsentrator

Are constitute element most importantly deep LAN. Hub Constitutes To Center Connection all node on network.

5.      Switch

Switch is tool that is utilized to link some LAN which is diqoined and provides filter package among LAN. Switch is instrumental multi port, with the meaning backs up one workstation.

Switch usually being utilized to increase network performance an organization by division jaringanyang outgrows in beberapajaringan that smaller, but is still provide interconnection that is equal to internetwork.

6.      WAP (wireless acces point)

WAP is instrumental one function as center of data communication in WLAN'S network (Wireless LAN), WAP uga functions as switch.

7.      Bridge

Bridge is tool that enables to divide a big network deep two smaller network, so becomes more network efficient.

8.      Repeater

Repeater is tool who can enforce (boost) network signal that gets through it. Repeater does support by fix signal electrical ala one be accepted and smoothens it that signal back. Repeater can as tool that separatedly or as one by konsentrator. Repeater is utilized if distance sails through signal that pass through distances overshot cable sail through cable default that is utilized.

9.      Router

Router is utilized to change information of one network one to the other network. Kindred Router with super's bridge smart (super intellegent is bridge). Router will choose band besting to overlooks an order,up on destination address and origin address. Router can lead data traffic to prevent subduction and last smart to know when to lead traffic along main band and alternative band. In network the world, router can as router factory brand, can also router its mean PC computer which often diseting becomes a router. Router is factory brand by a long shot expensive appealed by router PC, so by and large person liefing to utilize router PC. 

Reason why Tree's Topology said by rated topology

Treed topology is characteristic combine among star's topology and bus topology. This topology comprise of star's topology bulk that linked deep one bus topology as backbone. Linked computers goes to hub, meanwhile hub any other at connective as band of backbone or backbone. This network topology is so-called also as network topology of rated. This topology usually been utilized for sentral denganhirarki's squire interconnection that different

Data transmission on Topology

1.      Bus

On bus topology  two tips . shall be ended up by one terminator. Barel connector can be utilized to expand it. Network just consisting of one cable channel that utilize BNC'S cable. Computer that wants most link go to network that mengkaitkan can her with men tap s. along cable.

Bus network installation very simple, a bargain and maximal comprise of 5 7 computers. Handicap that often been faced is possible its happening data hit because simple relative network mechanism and if one of node hangs up therefore will trouble performance and trafik all network.

Specifik

• Long time technology, linked by one deep cable a line
• Don't need active equipment to link terminal / computer
• Really influential on unjuk communication job among computer, since just can be utilized by one computer
• Cable “ cut ” and utilized by konektor BNC type t
• At cable tip is assembled 50 konektor's ohms
• If disconnect cable therefore other computer can't get communication with other
• Distress does problem track
• discontinue Support.
•  

2.      Star

Star topology  constituting network topology form that as convergence from node intermediates to go to each node or user. Included star network topology network topology with intermediate cost.

3.      Tree

Partly peripheral really most straightforward link goes to central HUB, but plays favorites another most link pass through secondary HUB (pictured see).

On tree's topology exists two or more HUB which is utilized to link each peripherals into network. Entirely HUB that bases its function be divided as two a part which is Active HUB and HUB'S Liabilities.

Active HUB functions not only a only as router of data signal of one computer go to another computer, but also have function as Repeater .  Data signal that is sent of one computer goes to computer anothering to have limitation in term distance, after walks such a degree meter therefore that signal will ran down. With marks sense function Repeater this therefore that data signal will at - generate back to before then is kept on to computer that is wended, so distance sails through even data signal can more become not nearly that usually. Meanwhile HUB'S Liability just functioning as router of data signal of one computer goes to another computer.

On tree's topology, as on image, Central HUB is always as Active HUB whereas secondary HUB is HUB'S Liability. But on its performing, secondary HUB can also as Active HUB if is utilized to enforce back to data signal via another secondary HUB one most link.

Since basically this topology constitute wider form of star's topology, maka  is excess and its lack on star's topology also proprietary by tree's topology. In contrast is HUB and cable that utilizes to more become a lot of so needful planning which ripe deep its arrangement by regards alround one be braced, including in it is hall layout. Even so, this topology have top more can reach farther distance with activate proprietary Repeater function by HUB.

4.      Ring

with topology form that takes after ring (ring) this therefore data signal will move unidirectional of one peripheral goes to another peripheral until in the end stop at intent peripheral. In other words, to reach peripheral d. therefore signal which is sent from peripheral A shall pass through peripheral b and C.

About problem it is signal will progressively ran down if distance who shall be sailed through to reach to the effect getting far. Hence to settle namby pamby data signal because possible sail through limitations outdoor distance which be allowed, therefore each peripheral on this topology is proveded with one repeater. With marks sense Repeater, therefore data signal that passes through one peripheral will direct strengthened by back so gets' walking' continually go to another peripheral, such one goes on it until in the end that data signal is arriving at intent peripheral.

In term installation process and rekonfigurasi, Topology Ring can say relative edge out since each peripheral (well ala logik or physical even) most link one and just one by its beside peripheral.

Damage identification also easy relative, since data signal always moves continually of consigner peripheral until finally stop at intent peripheral. So if up to that trip one peripheral doesn't accept data signal in given time period therefore network operator will be reminded by its Alarming appearance that inform problem and its location position. Its weakness, since data signal moves unidirectional and through another peripheral for comes unto tujuan 's peripheral therefore damage / not its functioning one link will regard

The difference among windows server and linux server

The difference among linux's windows and server server in a general way lie on the side its server security, namely nurginal windows server its easier security dibobol instead of linux's server.

 The Diferent of LAN,MAN and WAN

LAN
A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link. Typically, connected devices share the resources of a single processor or server within a small geographic area (for example, within an office building). Usually, the server has applications and data storage that are shared in common by multiple computer users. A local area network may serve as few as two or three users (for example, in a home network) or as many as thousands of users (for example, in an FDDI network).

MAN

A Metropolitan area network (MAN) is a large computer network that usually spans a city or a large campus.

WAN

A wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances, using a communications channel that combines many types of media such as telephone lines, cables, and air waves. A WAN often uses transmission facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower three layers of the OSI reference model: the physical layer, the data link layer, and the network layer.
