võrgukaabli

Võrgukaabel, commonly known as an Ethernet cable, is a type of electrical cable used for transmitting data over a local area network (LAN). It is a crucial component in wired networking, connecting devices such as computers, routers, switches, and modems to each other and to the internet. The most common type of võrgukaabel is made of twisted pairs of insulated copper wires, typically enclosed in a protective jacket.

There are various categories of võrgukaabli, denoted by "Cat" followed by a number (e.g., Cat5e, Cat6, Cat6a). These categories indicate different performance standards, primarily in terms of bandwidth and data transfer speeds. Higher category cables generally offer better performance and are more resistant to interference. For instance, Cat5e cables can support speeds up to 1 Gigabit per second (Gbps), while Cat6 and Cat6a can handle higher speeds and frequencies.

The connectors used on võrgukaabli are typically RJ45 connectors, which are standardized plugs that fit into corresponding ports on network devices. The physical construction and shielding of the cable play a significant role in its ability to maintain signal integrity and prevent electromagnetic interference, especially over longer distances. Choosing the appropriate type of võrgukaabel depends on the specific networking requirements, such as the desired speed, distance, and the complexity of the network environment.
