2 Networks Data Communication
Transfer of digital data between between 2 or more remotely attached autonomous systems in a reliable and understandable manner

3 Networks Network – data communication between 2 or more devices with the ability to access shared resources LAN - local area network WAN - wide area network

4 Networks Topologies Bus Ring Star

5 Networks Components Hubs Switches Routers

6 Networks Components (Cont.)
Hub connects multiple devices on same network via individual dedicated cable runs (star topology) Switch provides a dedicated communication channel between network devices

7 Networks Components (Cont.)
Router connects between entities residing on different networks

26 Category 6 Standard ratified in 2002 Bandwidth 250 MHz
1GBit Ethernet applications Protocol running 1000BaseTx Full UTP/STP solutions The 1000BaseT protocol (IEEE) consists upon Cat5e ACR. Since the Cat5e has poor ACR the active switches needs to have a very good SNR – Signal to Noise Ratio (equivalent to ACR) to submit and receive the Ethernet signals. that effects on the cost of switches. Due to the fact that the Cat 6 has good ACR, in compare to Cat5e, the active switches can have least SNR and by that to be much more cheaper. Furthermore, you still can say that when using 1000BaseT and Cat6 you will have very low BER (Bit Error Rate) and that will increase your network reliability.

27 Category 6a Standard ratified in 2008 Augmented CAT6
Channel up to 100 m Bandwidth 500 MHz UTP and STP solutions New cable design (Horizontal and patch cords) Issues with Alien CrossTalk (AXT)
