IT networking refers to the practice of designing, implementing, and managing computer networks. A computer network is a collection of devices, such as computers, servers, printers, and other peripherals, that are connected together to enable communication and the sharing of resources.

IT networking includes a range of technologies and protocols, such as Ethernet, TCP/IP, Wi-Fi, and VPNs, among others. Networking professionals use these technologies to create and manage networks that can be used for various purposes, such as data storage and backup, communication and collaboration, and accessing the internet.

Networking includes designing and configuring network infrastructure, installing and maintaining network hardware and software, monitoring network performance and security, and troubleshooting network issues.

In recent years, the rise of cloud computing and mobile devices has led to significant changes in IT networking, with many organizations moving their networks to the cloud and adopting mobile device management strategies to enable secure access to network resources from anywhere.

IT networking is a complex and constantly evolving field, and networking professionals need to keep up with the latest technologies and trends to ensure that their organizations have reliable, secure, and scalable networks that meet their needs.
