Answer 2

Answer:

1. Fill in the blanks

1. Network design refers to the planning of the implementation of a computer network infrastructure. Network design is generally performed by network designers, engineers, IT administrators and other related staff. It is done before the implementation of a network infrastructure.

2. Data is the arrangement of the nodes connected to one another in a network

3. Point-to-point topology is the simplest of all the network topologies. The network consists of a direct link between two computers

4. star topology

A star topology, the most common network topology, is laid out so every node in the network is directly connected to one central hub via coaxial, twisted-pair, or fiber-optic cable.

5. star

6.  The mesh topology has a unique network design in which each computer on the network connects to every other. Tree topologies have a root node, and all other nodes are connected which forming a hierarchy.

2. Match the colums

1. The most common twisted-pair cable used in communications is referred to as unshielded twisted-pair (UTP). This is the most commonly used medium today, because of its usage in the telephone system. This cable can carry both voice as well as data. It consists of two conductors (usually copper).

2. Network design refers to the planning of the implementation of a computer network infrastructure. Network design is generally performed by network designers, engineers, IT administrators and other related staff. It is done before the implementation of a network infrastructure.

3.  Most coaxial cables have a characteristic impedance of either 50, 52, 75, or 93 Ω. The RF industry uses standard type-names for coaxial cables. Thanks to television, RG-6 is the most commonly used coaxial cable for home use, and the majority of connections outside Europe are by F connectors.

4. The basic structure of an optical fiber consists of three parts; the core, the cladding, and the coating or buffer. The basic structure of an optical fiber is shown in figure

5 .

Total internal reflection is the operating principle of optical fibers which are used in endoscopes and telecommunications. An optical fiber consists of a very thin core of high purity glass. The core is covered by a second layer (cladding) also made from high purity glass. The cladding is less dense than the core and has a lower refractive index  for total internal reflection to occur. Thus light rays passing along the core at an angle greater than the critical angle are totally internally reflected. The surface of the high purity glass core acts like a perfect mirror and the light ray is continuously reflected along the length of the optical fiber core.

6. A radome is a microwave antenna component that protects the antenna feed system and reduces windloading on the antenna. This blog offers insight into the choice of radome material for microwave antennas. Before explaining what I mean in the headline, it might be worth reviewing how radomes have evolved in microwave antennas over the years.

7 . A communications satellite is a space station that receives microwave signals from an earth-based station, amplifies (strengthens) the signals, and broadcasts the signals back over a wide area to any number of earth-based stations. ... Transmission from a satellite to an earth-based station is a downlink

8. Typically, Ethernet cables are used to provide an internet connection, connect devices to a local network. They plug into Ethernet ports on a variety of devices. The most common use for an Ethernet cable is connecting a WiFi router or modem to the internet entry port or telephone line.
