Term1
Network Hardware and Protocols

2. Startup Exercise Start your Packet tracer program:
Draw a Star topology network including the following (switch 2960 , A server , 3 desktop computers) – connect between them using copper straight cable )

3. Identify Network Hardware and components Describe network protocol
Unit3 Objectives:
Identify Network Hardware and components
Describe network protocol
Explain how data packets move across network
Design a computer network

4. Hardware: are all the parts that you can see and touch
Network Hardware
Hardware: are all the parts that you can see and touch

5. Software: is made up of all the programs and apps
Network Hardware
Software: is made up of all the programs and apps
Example of Software :

6. End Devices
End Devices (hosts): refers to all the devices used to send or receive data
Some examples of end devices are:
Computers (such as work stations, laptops, file servers and web servers)
Network printers
Telephones and teleconferencing equipment
Security cameras
Mobile devices (such as smart phones, tablets, PDAs, wireless debit/credit card readers and barcode scanners)

7. Network Interface Card (NIC)
Network Interface Card: is the port or card where the network cable is connected
NIC converts data signals into a signal that can be sent over the medium
Each NIC has a MAC address (unique address that identified each device on a local network)

8. Router Network Devices
Network Devices: help us to connect to all hosts together and to access to service on the network
Router

9. Network Devices - Switch
Switch: used to connect end devices to a LAN, it uses MAC address to send data frames to correct device

10. Network Devices - Router
Router: used to send packets from one LAN to another, it uses IP address to direct the data packets
