Line of sight (LoS) is a type of propagation that can transmit and receive data only where transmit and receive stations are in view of each other without any sort of an obstacle between them. FM radio, microwave and satellite transmission are examples of line-of-sight communication.
What is a circuit configuration?
Circuit configuration is the basic physical layout of the circuit. There are two fundamental circuit configurations: point-to-point and multipoint. In practice, most complex computer networks have many circuits, some of which are point-to-point and some of which are multipoint.
Is one of the most commonly used coding schemes used in data transmission?
ASCII(American Standard Code for Information Interchange) : ASCII may be considered the most widespread coding scheme used.
What determines a circuit’s capacity?
Every circuit breaker has a specified amperage (amount of current). This rating is labeled on the breaker itself. The standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage.
What are types of configuration?
The three types of configurations are Common Base, Common Emitter and Common Collector configurations. In every configuration, the emitter junction is forward biased and the collector junction is reverse biased.
What is data circuit used for?
In telecommunication, a data transmission circuit is the transmission media and the intervening equipment used for the data transfer between data terminal equipment (DTEs). A data transmission circuit includes any required signal conversion equipment.
What are 3 wireless media types?
Types of wireless transmission media used in communications include infrared, broadcast radio, cellular radio, microwaves, and communications satellites.
What is wireless transmission medium?
Wireless transmission medium that distributes radio signals through the air over long distances such as between cities, regions, and countries. AM/FM radio is broadcast radio. Slower and more susceptble to noise than physical transmission media.
Which of the following transmission media is used in Bluetooth technology?
Bluetooth uses a radio technology called frequency-hopping spread spectrum. Bluetooth divides transmitted data into packets, and transmits each packet on one of 79 designated Bluetooth channels.
What are the 3 types of codes?
- Boring Code. Boring code is when it makes perfect sense when you read it.
- Salt Mine Code. This is the type of code that’s bonkers and makes not a lick of sense.
- Radioactive Code. Radioactive code is the real problem at the heart of every engineering team.
Which line code among the following has a DC null in its power spectral density?
Bipolar signaling has several advantages: (1) its spectrum has a dc null. (2) its bandwidth is not excessive.
What are the types of coding in qualitative research?
Methods of coding qualitative data fall into two categories: automated coding and manual coding. You can automate the coding of your qualitative data with thematic analysis software.
Is a resistor a load?
In a circuit, an element which consumes electric power is considered as a load. Resistor also consumes power. So, resistor can be represented instead of load, or, every load is consuming power as the same way as resistor consumes. Example of load in electric circuits are appliances and lights.
How many types of circuit breakers are there?
There are three basic circuit breaker varieties: standard breakers (which include both single-pole and double-pole circuit breakers), ground fault circuit interrupter circuit breakers (GFCIs) and arc fault circuit interrupter circuit breakers (AFCIs).
How do you calculate current?
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).
What is configuration word?
Definition of configuration 1a : relative arrangement of parts or elements: such as. (1) : shape. (2) : contour of land configuration of the mountains. (3) : functional arrangement a small business computer system in its simplest configuration.
What is use configuration?
In computing, configuration files (commonly known simply as config files) are files used to configure the parameters and initial settings for some computer programs. They are used for user applications, server processes and operating system settings.
What is configuration data?
Configuration Data means the Facility-specific data that is used in conjunction with the Software, including without limitation, tuning and set point constants, graphical, pictorial and text files, that instantiate the Software for the specific Facility environment.
What is communication circuit?
The definition of communication circuit is used for physical communication line directly within which there is a signal transmission.
What is a circuit in a network?
In telecommunications, a circuit is the complete path that a message takes to go from the sender to the receiver and back again. Historically, for telegraphs and early telephone systems to work, they required a complete electrical path between the sender and receiver.
What is transport circuit?
Transport-circuit definition A circuit employed for long-haul carriage within the core or backbone of a wide area network (WAN). See also access circuit, long haul circuit, and transport.
What is frequency spectrum in computer networks?
Definition of ‘frequency spectrum’ A full-range device is any audio device capable of capturing, reproducing, or processing the full audio frequency spectrum of 20 Hz to 20 kHz. The frequency spectrum of an electrical signal is the distribution of the amplitudes and phases of each frequency component against frequency.
What is network topology class 8?
Network topology refers to the way a computer network is laid out, either physically or logically. It defines the way in which network devices are organized geometrically. In this topology all nodes are connected together to the parallel cable by drop lines and taps/T-connectors.
What is communication satellite How is it useful in the field of data communication?
A communication satellite is a microwave repeater station in a space that is used for telecommunication, radio and television signals. A communication satellite processes the data coming from one earth station and it converts the data into another form and send it to the second earth station.
What is radio signal transmission?
In radio transmission, electromagnetic power from a radio transmitter is coupled by the transmitter antenna into air or free space. In radio reception, electromagnetic radio waves are intercepted by a receiving antenna and coupled into a receiver for detection.
