Connection systems

The communication network on Earth and outer space is extremely complex and continuously expanded. These links allow us to communicate with anyone in a variety of ways, as well as improved link quality and quality than ever before.

TV connection . Every television station has a central control room. This control room uses computers to combine signals from a variety of live programs as well as playback so that TV programs are continuously broadcast. Signals from TV stations will be transmitted via fiber optic cable or radio waves to the camera of each family.

Computer network . This diagram shows us the computer network of the US National Scientific Research Agency. The network links scientists' computers across the United States, but it is just one of many networks that link personal computers together. Computers can link within an office, but they can also link to another computer in another country if they use the global internet.

Satellite From locations far away from Earth, telecommunications satellites operate on the same principle that the TV and radio signals on the ground are continuously transmitted. Satellite phones allow users in remote places without a wired and wireless phone network to make calls easily.

Phone cable . When using a desktop phone by pressing the number to call, the user will create an electrical signal that is transmitted from the phone to the nearest phone base station. These base stations use circuits and wires (as shown in the picture) to transmit signals to the point of connection and make a call. Phone signals can go through cables with copper or optical fiber cables, through radio waves, even relaying via satellites.

Microwave broadcast receiver . These huge columns of equipment are installed with receivers and transmitters and are tasked as microwave relay stations. The signal is transmitted through the air in the form of microwaves (a form of radio waves) and transmitted here. From the receiver, the wave continues to be transmitted to the next station. Microwaves can transmit TV signals as well as radio signals, phone calls, images and data from fax machines at almost instant speed.
