what is Computer networking
Computer networking is the practice of linking multiple computers and other devices together to share resources and information. It enables communication and data exchange between these devices, allowing them to work together, share data, and access the Internet. Computer networking is a fundamental component of modern computing and is essential for a variety of applications, including Internet connectivity: 

Computer networks provide access to the Internet, allowing users to browse websites, send email, stream video, and download files.

File sharing: Networks enable users to share files and data between computers. It is commonly used in offices for collaborative work and in homes to share media files.
Printers and Peripherals: Network printers and peripherals can be shared among multiple users, reducing the need for separate devices for each computer.

 Data storage: Network-attached storage (NAS) devices allow multiple users to store and access files on a centralized storage system.

Communications: Networks support a variety of communication methods, including email, instant messaging, video conferencing, and Voice over IP (VoIP) for making phone calls over the Internet.

Remote Access: Networks enable remote access to computers and resources, which is important for remote working, technical support, and server management.

Data Security: Networking also involves implementing security measures to protect data from unauthorized access, viruses and other threats.

Computer networks can vary in size and complexity, from small home networks connecting a few devices to large enterprise networks connecting thousands of computers, servers, and other devices across multiple locations. They may use a variety of technologies and protocols, such as Ethernet, Wi-Fi, TCP/IP, and more, to facilitate data transmission and communication.

The major components of computer networking include routers, switches, access points, network cables, and network protocols. The field of computer networking is constantly evolving to meet the growing demands of modern computing, and it plays a vital role in the way businesses, individuals, and organizations communicate and share information.
