What are computer network systems?

Computer network systems refer to interconnected groups of computers and devices that communicate and share resources such as files, applications, and internet access. These systems use networking hardware and protocols to enable seamless data transmission between users and devices within an organization or across the globe. They are essential for business operations, allowing for collaboration, data management, and secure communications. Network systems can range from small local area networks (LANs) to complex wide area networks (WANs) that connect multiple locations.
