Select all the True statements:
A network protocol is an agreed way of how to communicate over a network.
WiFi networks use radio frequencies in the 2.4 GHz or 5 Ghz frequency ranges.
WAP stands for Wide Area Protocol
2.4 GHz frequency networks are slower than 5GHz networks, but have a stronger signal range.
WiFi networks typically create a ring network topology
What are advantages of dividing network transmission into layers?
Network communication components are standardised which helps to ensure that different types of hardware and software are able to communicate.
Through separating the overall network communication processes it makes troubleshooting easier should an error occur.
To ensure that if changes are made in one layer they do not affect any other layers
Through dividing overall network communication into smaller, individual components it makes the software development process more straightforward.
Its easier
A router reads the ….
IP address
MAC address
Which of these is NOT correct of packet switching?
Messages cannot be easily intercepted
Establishes a route on which to send data packets
Packets need to be re-ordered
Maximises the use of the network
In packet switching each packet will follow the same route
True
False
What is packet switching?
A mode of data transmission in which a message is broken into a number of parts which are sent independently, over whatever route is optimum for each packet, and reassembled at the destination.
Data transmission
Optimum route
What does TCP/IP mean?
Traffic Control Protocol/Information Protocol
Transport Control Protocol/Intranet Protocol
Truck Car Protocol/Intranet Protocol
Transport Control Protocol/Internet Protocol
How is data sent?
Splitting them up
One huge packet
Why are packets split?
To make the data arrive in order
To make the data more manageable
To make it easier to transport
