These fibers make up thick cables that can be laid over long distances and can even transmit data to another continent; Bluetooth signals are transmitted wirelessly using radio waves at a frequency ( ) specifically designated for this purpose; in this way, the signal can be transmitted in a local network Dozens of meters. Network protocols: what they are used for and how they are arranged Read also Network protocols: what they are used for and how they are arranged More Satellite technology: Signals are transmitted via satellite and from there to the end user; feedback is done using standard technologies (, fiber optics). Currently, it doesn't matter which channel the signal travels through the computer network.

On the way to its destination, information Saudi Arabia phone number list may pass through sections that combine wired, optical and wireless technologies. Switched Two types of switching are used in computer networks: circuit switching and packet switching. In the first case, you need to connect the source to the destination before you start sending information. When communication is established, information is transmitted over dedicated channels. This technology is used for telephone connections.




If there is a problem in any area, the connection will be severed and signal transmission will stop. In such a network, re-switching is not possible and routing issues do not need to be dealt with. The second type of switching occurs when combining computers into a network. Here, the information is broken into individual pieces or packets, hence the name for this type of network. Each packet is transmitted individually and its route is not strictly defined. This ensures high connection stability. If any network element is defective, an alternative transmission path can be found. Switched Switched In short, the routing of individual packets at each stage is eliminated. However, this increases transit time and creates additional loads.
