What is the primary purpose of using repeaters in a network?

The primary purpose of using repeaters in a network is to extend transmission distance. Repeaters function by regenerating and amplifying signals, allowing data to travel further than it normally would over a specific medium, such as coaxial cable or fiber optics. This is particularly important in networks where distances may exceed the standard limits for reliable data transmission. By boosting the signal strength, repeaters help maintain performance and reduce the likelihood of data loss or degradation over longer distances.

Other options suggest functions that are not the primary roles of repeaters. For instance, creating network segments generally involves devices like switches or routers, which manage traffic flow between different segments rather than simply amplifying signals. Providing data encryption is a security function that is handled by specific security protocols or devices designed for that purpose. Increasing bandwidth refers to the capacity of a network to transmit data, which involves different techniques or technologies unrelated to repeaters, such as upgrading infrastructure or utilizing faster transmission media.
