Computer Networking – Introduction – Uses

What is Computer Networking?

Computer Networking : A network of connected computers that can Communicate and Share Resources is referred to as a Computer Network.

These Networked Devices send data Via Wireless or Physical Technologies According to a set of rules known as Communications Protocols.

How does a Computer Network Operate?

Computer networking’s Fundamental Building Components are Nodes and Links.

Data Terminal Equipment (DTE), which contains two or more computers and printers, or Data Communication Equipment (DCE), which includes a Modem, Hub, or Switch, can be Considered Network Nodes.

The transmission medium that Connects Two Nodes is referred to as a link.

Links can be vacant spaces used by wireless networks or they can be Physically Present, such as Cable Wires or Optical Fibers.

The rules or protocols that specify how to transmit and receive Electronic Data over the links are followed by nodes in a Functioning Computer Network.

These Physical and Logical Components’ Designsare determined by the Computer Network Architecture.

It offers the standards for the Physical Elements, Operational Structure, Protocols, and Practices of the Network.

What are Computer Networks Used for?

The earliest computer networks were created in the late 1950s for use in Defense and Military Applications.

They initially had Limited Commercial and Scientific Applications and were used to Transport Data Via Telephone Lines.

The development of Internet Technologies has made Computer Networks essential for Businesses.

More than just connectivity is provided by Contemporary Network Systems.

They are essential to Modern Company Performance and the Digital Transformation of Industries.

Network underpinnings now include more Programmable, Automated, and Secure Features.

Computer Networks of Today can:

• Operate Virtually:

Multiple “Overlay” networks can be created by Logically Partitioning the underlying Physical Network Architecture.

The nodes in an overlay Computer Network are Virtually Connected, and data can be sent between them Via Several Different Physical Channels.

For instance, the internet is used to overlay Numerous Business Networks.

• Integrate on a Large Scale:

Computer networks that are physically separated are connected by Modern Networking Services.

Through automation and monitoring, these services can enhance Network Operations and build a Single, Expensive, High-Performance Network.

Depending on Demand, Network Services can be scaled up or down.

• Respond Quickly to Changing Conditions

Many Computer Networks are defined by software.

A digital interface can be used to Centrally Route and Manage Traffic.

These Computer Networks allow for the Administration of Virtual Traffic.

• Provide Data Security

Access Control and Encryption are built-in Security Features in all Networking Technologies.

To increase Network Security, Third-Party Programs like Firewalls, Antimalware, and Antivirus Software can be integrated.

What are the Types of Computer Network Architecture?

Two main Categories can be used to Classify Computer Network Design:

• Client-Server Architecture

Nodes in this kind of Computer Network Could be Clients or Servers.

Client nodes receive resources from Server Nodes, such as Memory, Computing Power, or Data.

Client Node Activity may also be Controlled by Server Nodes.

Although clients can interact with one another, they do not Exchange Resources.

For instance, some computers in Business Networks save Information and Setup Preferences.

The network’s servers are represented by these Devices.

Clients can Request Access to this data from the Server Machine.

• Peer-To-Peer Architecture

The connected computers in a Peer-To-Peer (P2P) Architecture share the same Rights and Privileges.

No centralized server is present for coordination.

Each Computer Network device has the option of Serving or Acting as a Client.

A portion of each peer’s resources, such as Memory and Processing Power, may be shared across the entire Computer Network.

For instance, Several Businesses Host Memory-Intensive Programs, Including 3D Graphic Rendering, Across Multiple Digital Devices Using P2P Architecture.

What is Network Topology?

Network Topology refers to how nodes and links are Organized.

They can be set up in many ways to get Various Results.

Various network topologies include:

• Bus Topology

Each node has a Single Link to another node.

Data is only transmitted in one direction through Network Connections.

• Ring Topology

A ring is created by connecting each node to two others.

Data can move in both directions.

But a Single Node Failure might bring the Whole Network to a Halt.

• Star Topology

Several Client Network Devices are Connected to a central server node.

Given that data doesn’t have to pass Via Each Node, this Topology Performs better.

It is also more Trustworthy.

• Mesh Topology

Each node is Interconnected with Numerous other nodes.

Every node in the network is linked to every other node in a complete mesh architecture.

What Other Sorts of Business Computer Networks are There?

There are three Typical Forms of Enterprise Private Networks, which vary depending on the Needs and Size of the Organization:

• Local Area Network (LAN)

A LAN is a networked system that is constrained in terms of Size and Location.

Typically, it links computers and other devices together inside of a same Workplace or Structure.

Small Businesses make use of it or use it as a test network for Small-Scale Prototyping.

• Wide Area Networks (WAN)

A Wide Area Network (WAN) is an enterprise network that spans many Buildings, Cities, or even Entire Nations.

WANs are designed for Secure, Dependable Long-Distance Connectivity whereas Local Area Networks are utilized to Transport Data at Quicker Speeds when close by.

Software-Defined WAN, often known as SD-WAN, is a virtual WAN architecture that is Managed by Software.

Without compromising on Security and Service Quality, an SD-WAN offers more adaptable and Reliable Connectivity Services that can be managed at the Application Level.

• Service Provider Networks

Customers can lease Network Functionality and capacity from Service Providers using their Networks.

Telecommunications Businesses, Data Carriers, Wireless Communications Providers, Internet Service Providers, and Cable Television Operators that offer High-Speed Internet Access are examples of Network Service Providers.

• Cloud Networks

A cloud network can be conceptualized as a WAN whose infrastructure is provided by a Cloud-Based Service.

A Public or Private Cloud Platform Hosts some or all an Organization’s Network Resources and makes them available whenever needed.

Virtual Routers, Firewalls, Bandwidth, and Network Management Software are just a few of the Network Resources that may be provided, along with other Tools and Features as needed.

Today’s Businesses use cloud networks to shorten the time to Market, expand their Reach, and Efficiently Control Costs.

The preferred method forCreating and Deploying Apps for Contemporary Businesses is the Cloud Network Concept.
