• what is the difference among the people who work as system integrator, system administrator and network administrator and what is the task they perform.

• Answer:

  In IT, system integrators integrate multiple systems for inputting, processing, interpreting, storing, and categorizing data. For example, a system integrator may build an IT solution integrating an Oracle-based inventory tracking system, a document management system, a Microsoft CRM system, a group of Panasonic scanners, and a Rimage storage system to produce an overall solution for the customer. The duties of a system administrator are wide-ranging, and vary widely from one organization to another. Sysadmins are usually charged with installing, supporting, and maintaining servers or other computer systems, and planning for and responding to service outages and other problems. Other duties may include scripting or light programming, project management for systems-related projects, supervising or training computer operators, and being the consultant for computer problems beyond the knowledge of technical support staff. A System Administrator must demonstrate a blend of technical skills and responsibility. Network administrators are basically the network equivalent of system administrators: they maintain the hardware and software that comprises the network. This normally includes the deployment, configuration, maintenance and monitoring of active network gear: switches, routers, firewalls, etc. Network administration commonly includes activities such as network address assignment, assignment of routing protocols and routing table configuration as well as configuration of authentication and authorization – directory services
