A network is a system composed of computers, hardware and software related to networking and communication equipment such as cables and wireless devices. In general, networks are divided into hardware (Passive) and software (Active).
Key skills of a network professional
- Strong IT expertise, especially in hardware and software related to networks
- Organizational and task prioritization skills
- Ensuring the network can meet client needs with adequate security
- Ability to work in a team
- Familiarity with the main networks (LAN, MAN, WAN and GAN)
Related services for network troubleshooting
Local Area Networks (LAN) operate in a restricted space such as an office or building setting.
Metropolitan Area Networks (MAN) connect within a city. Wide Area Networks (WAN) connect systems across national borders. Global Area Networks (GAN) connect networks across unlimited geographical boundaries using wireless and satellite technologies.
Additionally, keeping systems up-to-date with the latest technologies and educating users on system usage are important, as is enhancing network security services.
What specializations should a network professional learn?
- Understanding the fundamentals of networking and cabling: knowledge of cables, hardware and software, bandwidth and the OSI model.
- Cisco training: working with Cisco devices and completing related courses such as CCNA and CCNP.
- Microsoft training: managing Windows Server, Active Directory, Group Policy, DHCP & DNS, and user access in Windows environments.
