Network services make it easier to operate a network over a computer. Based on network protocols running at the application layer in the Open Systems Interconnection (OSI) model of the network, it is often delivered by a server (which can execute one or more services). Domain name system (DNS), dynamic host configuration protocol (DHCP), and voice over internet protocol (VoIP) are some of the examples of network services.

In this article, we will be learning about the network services in computers.

Network services

We are going to discuss different kinds of network services in the following sections:

  1. Directory Services
  2. File Services
  3. Communication Services
  4. Application Services

(See, Network Layer)

Directory Services

These services map names to their values, which might be either variable or fixed. This software system aids in the storage of data, its organization, and the provision of numerous access methods.

  1. Accounting
    In an organization, the user names and passwords of the employees are linked to them. Directory Services allow us to store this information in a cryptic manner and retrieve them when needed.
  2. Authentication and Authorization
    At the time of login or on a regular basis, user credentials are checked to ensure that the user is authenticated. User accounts can be organized in a hierarchical structure, with authorization methods controlling their access to resources.
  3. Domain Name Services
    DNS is a widely used and important service that allows the internet to function. This technique converts IP addresses into domain names, which are easier to memorize and recall. Since IP addresses are used to manage networks and people remember website names, the DNS supplies a website's IP address, which is mapped to its name from the back-end when a user requests a website's name.

File Services

File services include file sharing and file transmission via a network.

  1. File Sharing
    File sharing was one of the factors that led to the development of networking. Users can share their data with other users through file sharing. The file can be uploaded to a server that is accessible to all intended users. As an alternative, the user can share his or her file on his or her own computer and grant access to only the people who need it.
  2. File Transfer
    This is the process of copying or moving files from one computer to another, or numerous computers, using an underlying network. The network allows its users to find and transmit files to other users on the network.

Communication Services

  1. Email
    Electronic mail is a form of communication that a computer user functions with. In today's world, the internet features are built on this foundation. There are one or more email servers in an email system. Each of its users is assigned a unique ID. When a user sends an email to another user, the email is transported between users through an email server.
  2. Social Networking
    Technology has made technical life more social in recent years. People who are internet knowledgeable can search for other people they know or even find friends, connect with them, and exchange their views, images, and videos.
  3. Internet Chat
    Instant text transfer between two hosts is provided via internet chat. Text-based Internet Relay Chat services allow two or more people to speak with each other. Voice and video chats are becoming popular these days.
  4. Discussion Boards
    Multiple persons with similar interests can be connected through discussion boards. It allows users to post queries, questions, and suggestions that are visible to all other users. 
  5. Remote Access
    This service allows users to access information stored on a remote computer. Remote desktop is the name for this feature. This can be accomplished via a remote device, such as a mobile phone or a home computer.

Application Services

These are simply network-based services such as web services, database management, and resource sharing that are provided to users.

  1. Resource Sharing
    A network provides a way to exchange resources efficiently and affordably. This could include things like servers, printers, and storage media.
  2. Databases
    One of the most significant services is the application service. It stores and processes Data and Information and allows users to obtain it quickly using queries. Databases assist organizations in making decisions based on statistics.
  3. Web Services
    The term "internet" is the new name for the World Wide Web. It connects to the internet and allows users to access files and information given by internet servers.

Frequently Asked Questions  

What are the benefits of computer network services?

The right network service can help your business grow and evolve. Not only does it allow staffs to share information effortlessly, increasing productivity, other benefits include cost-effectiveness, flexibility, and data security.

What is the network layer of the OSI Model?

Network Layer is the third layer of the OSI model. It handles the service requests from the transport layer and further passes them to the service request of the data link layer. This layer translates the logical addresses into physical addresses.

What are the services provided by the IP layer?

IP layer provides two major functions that are addressing and fragmentation. With regards to addressing, IP provides an unreliable, connectionless datagram delivery service.
