In Computer Networking, Transmission media can be defined as the physical paths between a transmitting device and a receiving device through which data signals are being sent from one end to another in a network.
Hence, transmission media comprise the path that data takes to flow between devices on the network.
There are basically two (2) main types of transmission media and these are;
1. Guided media: it is a media which uses a bounded or wired channel to transmit data at a secured and high speed. It comprises of coaxial cable, twisted-pair cable and fiber-optic cable.
2. Unguided media: it is typically a wireless transmission media such as infrared, microwaves, radiowaves through an unbounded channel.
First option is correct. A Surge Suppressor protects when + More than 110 volts.
Explanation:
- Sometimes the voltage of the connection quickly increases to a bigger higher value though for a very short period of time. This is called a spike.
- A surge suppressor is a device inserted in the AC utility line and telephone line to protect damage to electric devices from voltage spikes. They are a cheap way to protect the electric devices. They gives protection in amounts called joules.
- A surge suppressor stops the peak AC voltage from going above 110 volts.
