It is the responsibility of network and computer systems administrators for the day-to-day working of these networks. They arrange, establish, and assist an organization's computer systems. These networks may be local area networks (LANs), wide area networks (WANs), Metropolitan Area Networks(MANs), intranets, internet, and other data communication systems.

The basic dissimilarity between these two responsibilities is that a Network Administrator supervises the network, while a System Administrator is in the role of the computer systems – all the components that build a computer work.

Network administrators ensure that the organization’s computer networks are secure, protected, and working properly. A network administrator is an IT professional who confirms that the computer networks of an organization (collection of computers that share data with one another) are functioning to acquire the requirements of the organization.
