The term network services is used to describe a wide range of software and connectivity tools that are managed by a central group and distributed to networked computers. A networked computing environment occurs when multiple computers are connected to each other or to a central server. Computers can access shared files and utilities from a central location. There are several benefits to this type of environment, ranging from increased quality control to performance and problem management.
Server maintenance is a type of network service.
There are four types of network services: user management, email, printing, and system administration. In a network environment, desktops are known as client computers or workstations. Servers are typically stored in a special temperature-controlled room, often physically located in a different building or space than the workstation users. Access is provided by network cables that are used to transmit data packets within the network. These cables also provide access to the Internet, usually after routing through a central server or network switch.
System administration features are used in conjunction with manual troubleshooting to locate network problems.
User management is a range of services, from creating usernames and passwords to assigning rights, privileges and access. For example, when a new staff member joins a department, the network administrator must create a new account for that person to access network services. Access to applications, files, services, and tools that this person will require to complete their work must be provided by the system administrator. This is known as user authentication and administration.
Email is a widely used productivity tool that requires an Internet connection. In addition, many organizations have a policy on the email software that can be used, the maximum storage capacity, and the file sizes that can be transmitted. Most organizations provide employees with a company-specific email address, which requires the creation and maintenance of an email server.
Shared printing is one of the main network services required by any organization. Instead of individual printers at each table, all users can send print jobs to a central unit. This unit is usually a printer, scanner, and copier all in one. To provide this type of network service, many companies implement special printer management software to control document flow and protect sensitive documents.
From a system administration point of view, the ability to control all workstations from a central location is the best network service. The administrator is responsible for deploying new software applications, updating operating systems, and maintaining the same versions of software programs on all workstations. Many companies lock down workstations so that only the system administrator can add new software or run new programs. This increases the overall quality of the network and reduces the time staff spend on computer maintenance.
Copiers are often connected to a network, allowing users to schedule print jobs at their desks.
