Communications and Networks Question Answer _____ is a transmission media on which data, instructions, or information travel. communications channel A __________ is a LAN that uses no physical wires. WLAN. Transmission medium is the physical path through which the message travels from the sender to the receiver. Twisted pair cable, coaxial cable, fibre optic cable and radio waves are some examples of transmission medium. Transmission media carry data signals from one computer to another. Media are either wired or wireless. In modern networks, wired media use either twisted copper wiring, or fibre-optic cable . What is data transmission in IoT?Internet of Things (IoT) as an emerging technology is of interest to academia and industry. The collected data by IoT nodes will be transferred to a gateway server which may aggregate data and send it to a cloud platform for further data processing. Microwave System is not a transmission medium rather than it other options is used for transmission of data over a cables as well as lines. Guided − In guided media, transmitted data travels through cabling system that has a fixed path. For example, copper wires, fibre optic wires, etc. Unguided − In unguided media, transmitted data travels through free space in form of electromagnetic signal. For example, radio waves, lasers, etc. What is a transmission technology?Transmission technology generally refers to physical layer protocol duties like modulation, demodulation, line coding, and many more. It might also include higher-level protocol duties such as digitizing analog signals, data compression, etc. What kind of transmission medium is most appropriate to carry data in a computer network that is exposed to electrical interferences *?Answer: The optical fiber is made of glass or plastic. Transmission Media is broadly classified into the following types: Guided Media: It is also referred to as Wired or Bounded transmission media. (i) Twisted Pair Cable – Advantages: Advantages: (ii) Coaxial Cable – (iii) Optical Fiber Cable – (iv) Stripline. (v) Microstripline. What is transmission in data communication?Data transmission is the transfer of data from one digital device to another. This transfer occurs via point-to-point data streams or channels. These channels may previously have been in the form of copper wires but are now much more likely to be part of a wireless network. What are some examples of transmission?An example of transmission is when something travels over cable wires to get to its destination. An example of the transmission of a virus is when a person spreads a cold virus by sneezing on someone else. The sending of a signal, picture, or other information from a transmitter. Describes the type of physical system used to carry a communication signal from one system to another. Examples of transmission media include twisted-pair cable, coaxial cable, and fiber optic cable. There are two types of twisted pair cables used for most in-building situations today – Category 3 UTP (CAT 3) and Category 5 UTP (CAT 5). Which of the following is not a transmission system?Identify which of the following is not a transmission line? Explanation: The types of transmission line are telephone lines, power transmission lines, underground cables, coaxial cables, fibre optic cable transmission etc. Cavity resonators are not transmission lines, they are components that aid maximum transmission. Transmission Media is broadly classified into the following types: Guided Media: It is also referred to as Wired or Bounded transmission media. (i) Twisted Pair Cable – (ii) Coaxial Cable – (iii) Optical Fibre Cable – Unguided Media: (i) Radiowaves – (ii) Microwaves – (iii) Infrared –. What is networking Class 8 computer?A computer network is a set of computers connected together for the purpose of sharing resources. Other shared resources can include a printer or a file server. Is microwave a transmission medium?Microwave radio transmission is commonly used in point-to-point communication systems on the surface of the Earth, in satellite communications, and in deep space radio communications. Other parts of the microwave radio band are used for radars, radio navigation systems, sensor systems, and radio astronomy. 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 transmission means?: the act or process of sending electrical signals to a radio, television, computer, etc. : something (such as a message or broadcast) that is transmitted to a radio, television, etc. : the act or process by which something is spread or passed from one person or thing to another. Answer: Fiber optics is the fastest of the given data transmission techniques. In simplex transmission, signals are transmitted in only one direction; one station is a transmitter and the other is the receiver. Data Transmission mode defines the direction of the flow of information between two communication devices. It is also called Data Communication or Directional Mode. It specifies the direction of the flow of information from one place to another in a computer network. Detailed Solution Co-axial cable It is a type of wired medium for transmission. Microwave It is a type of wireless medium for transmission. Optical fiber It is a type of wired medium for transmission widely used in LAN Satellite It is a type of wireless medium for transmission. What is node in computer class 8?Node – The computers in a network can communicate with each other as well as work independently. Each computer in a network is called a node. A transmission medium is one which carries a signal from one computer to another. Wired transmission media includes twisted pair cable, Ethernet cable, coaxial cable and optical fibre whereas wireless transmission media includes microwave, radio wave, satellite, infrared, Bluetooth, WIFI etc. The physical means by which data is transmitted from one geographic or electronic location to another is called transmission, or “communication” media. Which transmission media provides the highest transmission speed in a network? Explanation: Fiber optics is considered to have the highest transmission speed among the all mentioned above. The fiber optics transmission runs at 1000Mb/s. How do networks transmit data?A wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication. Here’s what happens: A computer’s wireless adapter translates data into a radio signal and transmits it using an antenna. Which of the following defines how a network uses close range radio signals to communicate between two devices or objects equipped with this technology quizlet?A protocol, based on RFID, that defines how a network uses close-range radio signals to communicate between two devices or objects equipped with NFC technology. Developed by IEEE, towers can cover a 30-mile radius, and two types are fixed wireless and mobile wireless. What kind of communications device sends and receives data and information to and from a digital line such as ISDN and cable quizlet?Broadband modem that sends digital data and information from a computer to a DSL line and receives digital data and information from a DSL line. Broadband that sends digital data and information from a computer to an ISDN line and receives data and information from an ISDN line. Which of the following kinds of devices is any type of hardware capable of transmitting data?A communications device is any type of hardware capable of transmitting data, instructions, and information between a sending device and a receiving device. One type of communications device that connects a communications channel to a sending or receiving device such as a com- puter is a modem. Which of the following is a collection of computers and devices connected together via communications devices and transmission media quizlet?A network is a collection of computers and devices connected together, often wirelessly, via communications devices and transmission media. What is the amount of data that travels over a network called?Network bandwidth is a measurement indicating the maximum capacity of a wired or wireless communications link to transmit data over a network connection in a given amount of time.
