Verkkoliittimet, or network interfaces, are essential components in computer networks that enable communication between devices. They provide the physical and logical connections necessary for data transmission over a network. Network interfaces can be categorized into wired and wireless types.

Wired network interfaces use physical cables to connect devices. The most common wired interface is the Ethernet port, which uses twisted pair cables or fiber optic cables to transmit data. Ethernet interfaces operate at various speeds, typically ranging from 10 Mbps to 10 Gbps or higher, depending on the standard used.

Wireless network interfaces, on the other hand, use radio waves to transmit data without the need for physical cables. These interfaces are commonly found in laptops, smartphones, and other portable devices. Wireless standards include Wi-Fi (IEEE 802.11), Bluetooth, and Zigbee, each with different ranges and data transfer rates.

Network interfaces are implemented in various forms, such as network interface cards (NICs) for desktop computers and integrated interfaces in laptops and smartphones. They are responsible for handling data packets, managing network connections, and ensuring data integrity and security.

In modern computing, network interfaces play a crucial role in enabling seamless communication and data exchange between devices. They are integral to the functioning of local area networks (LANs), wide area networks (WANs), and the internet. Advances in network interface technology continue to improve speed, reliability, and security, supporting the growing demands of digital communication and data transfer.
