võrguüksused

võrguüksused refers to network devices or network elements in Estonian. These are the physical or logical components that make up a computer network and facilitate communication between devices. Common examples include routers, switches, hubs, modems, firewalls, and network interface cards (NICs). Routers are responsible for directing data packets between different networks, while switches connect multiple devices within the same network and forward data efficiently. Hubs, though largely outdated, serve a similar purpose to switches but broadcast data to all connected devices. Modems are used to convert digital signals from a computer into analog signals for transmission over telephone lines or cable networks, and vice versa. Firewalls act as security barriers, controlling incoming and outgoing network traffic based on predetermined security rules. Network interface cards are hardware components within a computer or other device that enable it to connect to a network. The term võrguüksused encompasses all these and any other hardware or software that plays a role in network infrastructure and operation, ensuring the flow of information and connectivity.
