Coaxial cable, often referred to as coax (pronounced KO-ax), consists of a single copper wire surrounded by at least three layers: (1) an insulating material, (2) a woven or braided metal, and (3) a plastic outer coating (Figure 8-25).
Is a network standard that specifies no central computer or devices?
Ethernet is a network standard that specifies no central computer or device on the network should control when data can be transmitted. Based on a bus topology, but can be wired in a star pattern.
What do you call an electrical disturbance that can degrade network communications answer?
Which of the following terms is an electrical disturbance that can degrade communications? Noise.
Which of the following is true of broadcast radio with regard to physical transmission media group of answer choices?
Which of the following is true of broadcast radio with regard to physical transmission media? It is slower and more susceptible to noise. Digital communications describes a process in which two or more computers or devices transfer all of the following EXCEPT ____.
Which of the following cables can be used to transmit signal in the form of light?
Fiber optic cable, also called as optical fiber cable, is a type of Ethernet cable which consists of one or more optic fibers that are used to transmit data. Fiber optic cable transmits data as pulses of light go through tiny tubes of glass.
Which network type connects each computer and device to a central device?
Alternatively referred to as a star network, star topology is one of the most common network setups. Every node connects to a central network device in this configuration, like a hub, switch, or computer.
What is the central device in a wireless network called?
A network hub is a node that broadcasts data to every computer or Ethernet-based device connected to it. A hub is less sophisticated than a switch, the latter of which can isolate data transmissions to specific devices. Network hubs are best suited for small, simple local area network (LAN) environments.
Networking cables are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printers, scanners etc.
What is the term used to connect a device to a network that has an IP address quizlet?
Terms in this set (34) What is the purpose of hubs and switches? to provide a central point for cables in a network. What is the term used to connect a device to a network that has an IP address? node.
Which of the following is a wireless transmission medium that distributes radio signals through the air over long distances?
Broadcast radio is a wireless transmission medium that distributes radio signals through the air over long distances such as between cities, regions, and countries and short distances such as within an office or home.
Which of the following are radio waves that provide a high speed signal transmission?
1 Introduction. Millimeter wave is a radio wave with a frequency between 30 and 300 GHz. Millimeter wave radio offers several advantages over lower frequency microwave radio. Its wide bandwidth enables a very high data transmission rate of up to 80 Gbit/s or even higher.
What kind of transmission medium is most appropriate to carry data in a computer network that is exposed to electrical interferences?
This is Expert Verified Answer The transmission medium that is appropriate in this case is an optical fiber. Glass or plastic are materials used to make optical fibers.
Which of the following device is used for internet connection a switch B router C modem?
Router. A router is a hardware device that allows you to connect several computers and other devices to a single Internet connection, which is known as a home network.
What are two types of wireless transmissions?
- Satellite Communication. Satellite communication is a crucial form of wireless communication.
- Infrared Communication.
- Broadcast Radio.
- Microwave Communication.
- Mobile Communication Systems.
- Bluetooth Technology.
What is LAN WAN man?
LAN stands for local area network. MAN stands for metropolitan area network. WAN stands for wide area network. Geographic Span. Operates in small areas such as the same building or campus.
What is LAN and its types?
In general, there are two types of LANs: client/server LANs and peer-to-peer LANs. A client/server LAN consists of several devices (the clients) connected to a central server. The server manages file storage, application access, device access, and network traffic.
How is WAN different from LAN?
A LAN, abbreviated from Local Area Network, is a network that covers a small geographical area such as homes, offices, and groups of buildings. Whereas a WAN, abbreviated from Wide Area Network, is a network that covers larger geographical areas that can span the globe.
What are the 4 types of network cables?
- Coaxial Cable. This system is rarely used.
- Shielded Twisted Pair (STP) Cable. It is mostly used in business installations.
- Fibre Optic Cable. It consists of several layers of protective materials that surround a centre glass core.
- Unshielded Twisted Pair Cable.
Which type of network cable is used to connect the components that make up satellite communication systems?
Explanation: Coaxial cable is commonly used to connect the various components that make up satellite communication systems and cable TV.
What type of cable is made of glass or plastic conductor that transmit information using light?
In a fibre-optic cable, light signals are transmitted through thin fibres of plastic or glass from light-emitting diodes or semiconductor lasers by means of internal reflection.
How many types of network are there?
LAN, MAN, and WAN are the three major types of networks designed to operate over the area they cover.
What kind of communication device sends and receives data and information to and from a digital line?
ISDN and DSL Modems A DSL modem sends digital data and information from a computer to a DSL line and receives digital data and information from a DSL line.
Can LAN be wireless?
A LAN can use wireless communication, wired connections or both. A wide area network usually traverses multiple geographical areas.
Is WiFi a LAN?
WiFi is a wireless network to connect nearby devices with each other and share the Internet via hotspots. Ethernet, on the other hand, is a LAN network standard used in wired LAN.
What is WLAN and WiFi?
A wireless local-area network (WLAN) is a group of colocated computers or other devices that form a network based on radio transmissions rather than wired connections. A Wi-Fi network is a type of WLAN; anyone connected to Wi-Fi while reading this webpage is using a WLAN.
