What is a media connection in networking?
What type of networking media uses electrical impulses to encode data?
Which type of network component can be used to share an attached printer to the network?

Modern networks primarily use three types of media to interconnect devices and to provide the pathway over which data can be transmitted. As shown in the figure, these media are:

Metallic wires within cables

Glass or plastic fibers (fiber optic cable)

Wireless transmission

The signal encoding that must occur for the message to be transmitted is different for each media type. On metallic wires, the data is encoded into electrical impulses that match specific patterns. Fiber optic transmissions rely on pulses of light, within either infrared or visible light ranges. In wireless transmission, patterns of electromagnetic waves depict the various bit values.

Different types of network media have different features and benefits. Not all network media has the same characteristics and is appropriate for the same purpose. The criteria for choosing network media are:

The distance the media can successfully carry a signal

The environment in which the media is to be installed

The amount of data and the speed at which it must be transmitted

The cost of the media and installation

Which three factors should be considered when choosing the appropriate network media choose three?

Which three factors should be considered when choosing the appropriate network media? (Choose three.).

the data security and fault tolerance requirement..

the environment in which the media is installed..

the amount of data and the data transfer rate desired..

the operating systems used on network devices in the network..

What is a media connection in networking?

Network media refers to the communication channels used to interconnect nodes on a computer network. Typical examples of network media include copper coaxial cable, copper twisted pair cables and optical fiber cables used in wired networks, and radio waves used in wireless data communications networks.

What type of networking media uses electrical impulses to encode data?

On metallic wires, the data is encoded into electrical impulses that match specific patterns. Fiber optic transmissions rely on pulses of light, within either infrared or visible light ranges. In wireless transmission, patterns of electromagnetic waves depict the various bit values.

Which type of network component can be used to share an attached printer to the network? Answers Explanation & Hints: A peripheral is a device that is not directly connected to a network. In order to be made available on a network, a host is responsible for sharing the peripheral across the network.

What term describes the interference when electrical impulses from one cable cross over to an adjacent cable?

Crosstalk is a disturbance caused by the electric or magnetic fields of one telecommunication signal affecting a signal in an adjacent circuit.

What type of network cable contains multiple copper wires and uses extra shielding to prevent interference?

STP and UTP Characteristics STP features two insulated copper wires that are twisted around one another and then covered with an additional shield. This extra covering boosts interference protection. STP is often utilized in Ethernet applications. UTP cables are a popular cable choice for LANs.

Which type of Ethernet cable should be used to directly connect two devices that both use the same pins for transmitting and receiving data select one?

An Ethernet crossover cable is a crossover cable for Ethernet used to connect computing devices together directly. It is most often used to connect two devices of the same type, e.g. two computers (via their network interface controllers) or two switches to each other.

Which type of network component is used to interconnected computing devices?

Transmission Media - Transmission media are the facilities used to interconnect computers in a network, such as twisted-pair wire, coaxial cable, and optical fiber cable. Transmission media are sometimes called transmission medium channels, links or lines.
