Introduction
Network engineers set up, develop and maintain computer networks within an organization or
between organizations.
You will offer support to users, who can be staff, customers, clients and suppliers, and solve any
problems. In some cases, this may involve designing new networks.
Your goal is to ensure the integrity of the high-availability network infrastructure to deliver maximum
performance to your users
Network Types
You will work with a variety of network types, such as:

• Local Area Networks (LAN) – connecting a limited area such as a house, office or a small group

of buildings,

• Metropolitan Area Networks (MAN) – connecting a large area such as a campus,
• Wide Area Network (WAN) – connecting networks nationally or internationally,
• Wireless Local Area Network (WLAN),
• Storage Area Network (SAN) – storage/system/server/small network,
• Campus Area Network (CAN) – network covering an educational or corporate campus,
• Desk Area Network (DAN) – office network, interconnection of workstations, and multimedia

devices,

• Voice over Internet Protocol (VoIP) – method and group of technologies delivering voice

communications and multimedia sessions.
