Administrators usually focus on the day-to-day operations of a computer network, ensuring that everything runs smoothly, overseeing upgrades and troubleshooting any problems that may arise. This can include adding new users to the network, performing network security audits, monitoring, evaluating and optimizing network or system performance. The job often involves training employees to use new hardware or software as it's introduced to the organization.

Network architects, as the title implies, usually focus on the design of the network, ensuring that the network will perform in accordance with the company's growth. This includes planning new networks and network upgrades, researching new technologies, upgrading hardware and software as needed for growth, while ensuring information on the network will be secure.

Education Requirements
To start working as a computer network engineer, you may only need a high school diploma, or an associate’s degree. However, most employers do ask for a bachelor's degree in a computer-related field like computer science, information science, or computer engineering. In some cases, a degree in electrical engineering may be acceptable.

For computer network engineers, education never ends. You will have to keep up with new technologies and many employers may require that you get certification from software companies or hardware manufacturers to work on their systems. Certifications and the required training are usually offered directly by the companies that make the products, such as Microsoft or Cisco.
