Key Hard Skills

Network administrators acquire hard skills through educational programs and practical experience. With knowledge of network types and functions, these professionals build competencies in programming languages, software and hardware management, and network security. These essential skills allow network administrators to carry out best practices as reliable professionals.

Local Area Network: Local area networks (LAN) connect computers within limited areas, such as rooms, buildings, or collections of buildings. LANs serve anywhere from two to hundreds of users, allowing for connection, communication, and collaboration. Network administrators understand and implement LAN software and hardware requirements while maintaining and updating their functions.

Wide Area Network: A wide area network, or WAN, covers a large geographic radius, connecting computers for private telecommunications. WANs incorporate LANs, often bringing together groups in distant cities, states, or countries. Network administrators supervise the installation and maintenance of WANs from a designated central location or by visiting remote locations.

Virtual Private Network: A virtual private network, or VPN, uses public networks to carry out private communication, data sharing, and related activities. Network administrators install and oversee VPNs. Most often employed over the internet, VPNs encrypt connections to ensure safe transmission of electronic information. VPNs also restrict outside access, allowing only authorized users to work remotely without interference.
Cisco Networking: Cisco, the company responsible for creating and manufacturing a great deal of networking hardware, offers certifications for network administrators. Most network administrators work with Cisco products and systems on a daily basis. For this reason, network administrators should understand these systems, their functions, and how to maintain and troubleshoot them.

Microsoft Active Directory: Companies that utilize Microsoft operating systems make use of an Active Directory, which creates and maintains various security policies for the entire computer network. Network administrators use this directory to authenticate users and allow employees different levels of system access.
