Telecom phone
- In an analog telephone network, the caller uses various telephone exchange switches to connect with the person he wants to talk to. The switch makes electrical contact between the two users. When the caller dials this number, the movement of the switch is determined by electricity. After being connected, the caller's voice sends a signal to the other party via the network.
- Fixed-line telephones in most homes are analog, that is, the speaker's voice directly determines the voltage of the signal. But the telephone company transmits in digital form; the signal is converted into analog form before it reaches the user. Multiple digital signals can be transmitted through the Internet at the same time, and can be fully restored after remote transmission.
- Mobile phones have an important impact on the telephone network; in many markets, mobile phone users have outnumbered landline phone users.
Telecommunications radio and television
- A broadcasting system high-power broadcasting tower transmits high-frequency electromagnetic waves to many low-power receiving stations. The high-frequency electromagnetic waves sent by the tower are modulated with visible or acoustic information. The receiving station receives high-frequency electromagnetic waves and demodulates signals containing visible or acoustic information. The broadcast signal can be an analog or digital signal.
- The broadcast media industry is now a turning point in its development process, with many countries moving from analog to digital broadcasting; this is due to the possibility of producing cheaper, faster, and larger-capacity integrating circuits. The main advantage of digital broadcasting is that it can prevent many dissatisfaction with ordinary traditional analog broadcasting; for television, these include snowflake pictures, ghosting and distortion. This is due to the nature of the analog transmission; interfering noise appears when it is finally released. Digital transmission overcomes these problems. Because digital signals reduce discontinuities during reception.
Telecom internet
- The Internet is a computer and computer network, a worldwide network through Internet protocols; it can communicate with each other. Any computer on the Internet has its own unique address, and other computers can communicate with it. In this way, any computer on the Internet can send a message to the inherent address of another computer, so that the Internet can exchange information between computers.
- It is estimated that in 2000, 51% of the information was transmitted through a two-channel telecommunication network; the rest was transmitted through land-based telephones, and in 2007 it accounted for 97% of all telecommunication network information.
Telecom local and large area networks
- Regardless of the growth of the Internet, the characteristics of local networks remain. It is only (a few kilometers in size). The advantage is cheaper and more efficient; and it has strong confidentiality.
- There are also independent large-area networks-private computer networks that can extend thousands of kilometers away. The advantages of this type of network are: strong privacy; security, regardless of potential computer hacking.
- Naturally, using local and large-area networks, including the military and intelligent managers, they must ensure that their information is secure and confidential.
