Network engineers play a crucial role in the organizational structure of companies across industries. They are the unsung heroes who ensure seamless communication, data sharing, and workflow efficiency. Without their expertise, businesses would struggle to function effectively in today's technology-driven world.

Imagine a scenario where employees can't access the company's shared files, emails are constantly delayed, and video conferences are riddled with glitches. This nightmare becomes a reality when network engineers are not present to maintain and optimize the organization's IT infrastructure.

Network engineers are responsible for designing, implementing, and managing the network systems that connect all the devices and people within an organization.
