Quick Answer: What is transmission medium and its types?

There are two types of transmission media, namely guided and unguided. Guided transmission media are cables like twisted pair cables, coaxial cables, and fiber optic cables. Unguided transmission media are wireless, such as infrared, radio waves, and microwaves.

What is physical transmission medium?

A physical medium in data communications is the transmission path over which a signal propagates. … With guided transmission media, the waves are guided along a physical path; examples of guided media include phone lines, twisted pair cables, coaxial cables, and optical fibers.

What is bandwidth of transmission medium?

If we assume a signal to be composed of a various number of frequencies, then Bandwidth is defined as the difference between the highest frequency and the lowest frequency of the signal.

What transmission means?

What are the three types of network media?

There are three general classes of media types: coaxial cable, twisted pair and fiber optic cable.

What are protocols?

In networking, a protocol is a set of rules for formatting and processing data. Network protocols are like a common language for computers. The computers within a network may use vastly different software and hardware; however, the use of protocols enables them to communicate with each other regardless.

What is the difference between STP and UTP?

Shielded twisted pair cable (STP) has the individual pairs of wires wrapped in foil, which are then wrapped again for double protection. Unshielded twisted pair cable (UTP) has each pair of wires twisted together. Those wires are then wrapped in tubing without any other protection.

What is the transmission speed?

Transmission speed is the rate at which data packets cross a computer network from one server to another. Transmission speed is typically measured in megabits per second (Mbps), which equals one million bits per second, although gigabit and even terabit speeds are becoming common.
