Network services are the basic reason we connect computers to each other.
Services are what a company wants to have performed or provided.
Based on the services a company wants to utilize, the company purchases a specific program and operating system.
Common services available on computer networks are;
1) Basic Connectivity Services
The PCs in a network must have special system software that enables them to function in a networking environment.
2) Redirector Service
2) Redirector Service
A network client must have a software component called a redirector.
In a typical standalone PC, I/O requests pass along the local bus to the local CPU.
The redirector intercepts I/O requests within the client machine and checks whether the request is directed toward a service on another computer.
If it is, the redirector directs the request toward the appropriate network entity.
The redirector enables the client machine to send information out of the computer, provided that a transmission pathway exists.
3) Server Service
3) Server Service
A network server machine must have a component that accepts I/O requests from clients on the network and that fulfills those requests by routing the requested data back across the network to the client machine.
In Windows NT, the server service performs the role of fulfilling client requests.
4) File Services
4) File Services
File services enable networked computers to share files with each other.
5) File Transfer Services
5) File Transfer Services
FTP uses communication software to dial up another computer and transfer files using a modem or a direct serial connection.
With a network, users have constant access to high speed data transfer without leaving their desks or dialling another computer.
Making a file accessible on a network is as easy as moving it into a shared directory.
6) Database Services

Database services enable applications to be designed in separate client and server components, such applications frequently are called client/server databases.
