Unit 1.5V2 Network Topologies

Unit 1.5V2 Network Topologies

1. Star Toplogy

   • Each device has its own cable that connects it to the switch.
   • Expensive to install
   • Extra hardware might be required
   • If the hub or switch fails all devices will be affected.
   • The server connects to the switch and the switch connects to all devices

2. Mesh Topology

   • Connecting a small network of computers together.
   • All devices are linked together

3. More susceptible to attacks.

4. There is no need for a direct connection.

5. Can connect to multiple devices.

6. Tend to have slower transfer speeds.

7. Interference can happen some times.

8. Protocol is a set of rules to tell you how to communicate with devices

9. The connection isn’t stable

10. IP addresses are either 32 or 128 bit.

    • TCP and IP are used to transmit data.
    • Data is split up into packets
    • IP addresses can change over time but MAC never change.
    • Static IPs never change but dynamic do

11. POP3 protocol Devices can only receive data

12. FTP file transfer protocol used when sending large files

13. HTTPS encrypted (secured data transmission)

14. SMTP sending e mails only

15. VIOP sending voice messages

16. TCIP Checks Source Destination Packet Order Data Error Check
