It means sharing some info or information from cardinal station to anformer(a) or with some superstar. The main source of communication is language. in that respect are some other ways for communicating likeThe wasting disease of Symbols.Road signs for the movement of vehicles.In military defense, we intake secret codes for confidential communication.Types of Communication There are three types of communicationVerbal Communication.Non-Verbal Communication.Visual Communication.Verbal CommunicationThe communication which is in formal way to win over or communicate from one individual to another. It has further two typesWritten Communication T he communication which is in written form like documents , emails , chats , SMS.This kind of communication is similarly used in patronage proposal, issusing levelheaded instructions contracts, memes. To make effective written communication, it depends on vocabulary, styles, clarity and also grammer.Oral Communication The communication which is hardiness to face of spoken words. It could also be on phone call, audio recording/video call and also video conference through internet. People give interviews to international companies for job on Skype.It could be formal or informal communication. Formal Communication The communication in which conferences, lectures takes place.Informal Communication The communication in which gossips with friends, injection jokes takes place.Non-Verbal communicationThe communication which is in formal way to exchange or communicate from one person to another.This communication can be done by form language which includes facial expressions, eye conta ct, body posture, gestures and others. But the most common of all is facial expressions.Visual CommunicationA communication in which an bringing close together or information that can be read or viewed by using visual back up like drawing, signs, typography, graphic design and other electronic devices.The profit and loss of business can be view by graphs or charts through which employees can present the profit and loss of business actually easily.Wireless CommunicationA communication in which data or information can be consign or receive without any cables or wires to another device. The information is transmitted through air by electromagnetic waves like radio frequency, infrared, satellite and much more. Now there are variety of devices and technologies ranging from smartphones to laptops, tablets, printers, bluetooth, Wi-Fi, 3G and 4G and so onTypes of Wireless Communication There are three types of Wireless CommunicationWireless Personal force field Network (WPAN).Wireless Local land Network (WLAN).Wireless metropolitan Area Network (WMAN). Wireless Personal Area Network (WPAN)The system which connect two devices at real short betray. They must be in truth close to individually other usually in the same room. Bluetooth It is two way communication between two devices which could be place very close to each other for sharing data or any information.It is very efficient reducing the wires like connect a mouse with computer, headphones, MP3 and cellphones etc. infrared (IR) Wireless Communication In this system, data or information is carried over infrared waves between two points. The frequency drift is in between the microwave and visible light.These are very small range of distance like TV remote and AC remote. Wireless Local Area Network (WLAN)It is topical anesthetic area network which connects two or more transceivers by using a wireless device. It cover the house or small offices under the WLAN.Wi-Fi A system that is related to computer net working. In this, we emergency wired connection of internet with guided router which connects to other devices like officious, laptops, tablets and LED TV. Its range is generally one home or small offices.If we use in large campus or hospitals then we use range extender to make the range much more and cover the whole area under the network. Wireless Metropolitan Area Network (WMAN)It is the communication network which have to covered the large areas , states or countries to communicate with each other. For this purpose, we use satellite communication or contagion tower to communicate with other very desire range places and take care by service picturer. satellite CommunicationAn artificial satellite that provide us facilities for communication as radio, television, telephones transmission and communicate with other countries by video or audio calling, texting and so on.The heart of a satellite communication system is a satellite based transmitting aerial in a stable orbit above the Earth.There are many satellites that relays on the quadriceps femoris to communicate with each other as serve as relay station in space. The overture station on near the Earth are referred to as Earth Stations. A transmission from an Earth station to the satellite is referred as Uplink. A transmission from satellite to an Earth station is referred as Downlink.The component in satellite which takes an uplink and convert into downlink signals is known as Transponder. There are number of ways of categorizing satellite communication-Coverage AreaIt covers the global, regional and national. The larger the area of coverage, the more satellites must be intricate in a single networked system.Service TypeFixed service satellite, broadcast service satellite and mobile service satellite.General UsageCommercial, Military, Amateur and Experimental.Protocols for Satellite Communication The protocols for Satellite Communication are theseMPEG It stands for achievement Picture Expert Group . It is the dominant standard used for TV encoding and transmission.IP It stands for Internet Protocol. It is the entire family of data communication protocols which is popular for emails and web-browsing.Why use of Satellite Communication?We use satellite communication for television, telephones, navigations, business and finance, weather, safety, development and a lot of more. Let us take some scenario to show why we use satellite communication?ScenarioIf we let out approximately television, you watch TV and there are hundred of bring on TV which are broadcast from many countries and there are some news channels, movies channels, gambol channels, sports channels and also animated channels for children.People get to know about the situation of other countries through news if there get out be no satellite then there will be no broadcast and no channel will appear on TV. If we talk about Telephones, we can call on airplanes through flight phone communication which is provided b y satellites to communicate with sylvan areas.Also through satellite, we can make our audio and video calls and talk from one country to another. If we talk about navigators, when you like to visit a place with friends and family but you lost the way that which is the right one. So, you use navigator which is in your cellphone and connect it with GPS through satellite to know about your location which is very helpful to get the right path and you can easily reach to your destination without any problem.Advantages of Satellite CommunicationIt is use for wireless communication.It is use for navigation.It covers the wide area of region or country with one satellite It is also use for audio/video calls and for transmission of data.It is use for connecting small areas, broadcasting TV/radio and also tell us about weather situations.
