Unit 1.5V2 Network Topologies

Star Toplogy
1. Each device has its own cable that connects it to the switch.
2. Expensive to install
3. Extra hardware might be required
4. If the hub or switch fails all devices will be affected.
5. The server connects to the switch and the switch connects to all devices
Mesh Topology
1. Connecting a small network of computers together.
2. All devices are linked together
More susceptible to attacks.
There is no need for a direct connection.
Can connect to multiple devices.
Tend to have slower transfer speeds.
Interference can happen some times.
Protocol is a set of rules to tell you how to communicate with devices
The connection isn’t stable
IP addresses are either 32 or 128 bit.
1. TCP and IP are used to transmit data.
2. Data is split up into packets
3. IP addresses can change over time but MAC never change.
4. Static IPs never change but dynamic do
POP3 protocol Devices can only receive data
FTP file transfer protocol used when sending large files
HTTPS encrypted (secured data transmission)
SMTP sending e mails only
VIOP sending voice messages
TCIP Checks Source Destination Packet Order Data Error Check
