CONNECTING TO A NETWORK (part 1) sambungan

yeahhhhh sambung lagi... malam ni nk tulis dlm bahasa enggeris pulak lah... jenuh nk translate kot BM... macam susah je Telekomunikasi dlm bm

ok jom sambung.....

TYPE OF NETWORKING INTERFACE (NIC)

Ethernet Cards

• Ethernet cards cointain connection for either coaxial or twisted pair cables (or both)

                  - BNC (Beyonet Neill-Concelman) connection for coaxial cable

                  - RJ-45 connected for  twisted pair

• some ethernet cards also have Attachment Unit Internet (AUI) connection

LocalTalk Connectors

• LocalTalk is Apple's built-in solution for networking Macintosh computers
• utilizes a special adapter box and a cable that plugs into the printe port of a Macintosh
• A major disadvantage of Localtalk (.23Mpbs) is that it is slow in comparison to Ethernet (10 Mpbs)

Token Ring Cards

• Token Ring network cards look similar to ehternet cards
• one visible diffrence is the type of connector on the back end of the card

4. CONCENTRATOR/HUB

• Central connection point
• transmit all data receive all node connected to the hub. Regardless to which device the data being sent to lots of extra network tarffic, network less efficent

5.SWITCH

• Switch vs hub : Both device contain ports to connect the devices together via networking cables and two facilitates communication between the devoce but they differ in how they transfer data
• identifies the device on the network for which the data is intended and sends the data to that node only
• can connect ethernet token rin fibre channel or other types of packet, switched network segment  together to from an internet
