What does a Linux Administrator do?
Network administrators are responsible for the implementation, management, and troubleshooting of a company's networks that rely on hardware and software. They will analyze the company’s needs and install and maintain the necessary hardware and software and solve any problems or technical issues that may arise along the way.
Network administrators install and support the company’s network and computer systems, which includes oversight of the communications systems to ensure that information flows properly within an organization. They continually monitor data to ensure the system is optimized, and they look for problems or issues that could either be caused by the network or potentially by another user. They ensure that new users are properly trained on network usage, and they train fellow employees on how to properly upload and download material that has the potential to impact the integrity of the network. They are also responsible for the maintenance and repair of personal computer local area networks, wide area networks security, and internet systems. Network administrators need a minimum of a certificate or an associate’s degree in a computer-related discipline. Employers often require a bachelor’s degree in computer science, information technology, or related fields.
