Support, Networking and Administration

Helpdesk
A typical help desk has several functions. It provides the users a single point of contact, to receive help on various computer issues. The help desk typically manages its requests via helpdesk software, such as an issue tracking system, that allows them to track user requests with a unique number. This can also be called a "Local Bug Tracker" or LBT.

Desktop Support
The Desktop Support Engineer is responsible for the  desktops ,  laptops , and  peripherals , such as  personal  digital assistants . The helpdesk will assign the desktop team the second-level deskside issues that the first level was not able to solve. They set up and configure computers for new users and are typically responsible for any physical work relating to the computers such as repairing software or computer hardware issues and moving workstations to another location.

Network Admin
The Network Administrator is responsible for the network software, hardware and infrastructure such as servers, switches, backup systems and firewalls. They are responsible for the network services such as email, file, and security. The helpdesk will assign the network team issues that are in their field of responsibility.

Server Admin
Server Administrators are responsible for most, if not all, of the servers within the organization. This includes, but is not limited to, DNS or Domain Name System Servers, Network Authentication, Network Shares, Network Resources, Email accounts, and all aspects of server software. It also includes more advanced services such as databases, Storage or Content Management Systems, specialized proprietary services, and other industry-specific server-based applications.
