Basic characteristics of Computer Networks

We will discuss these basic characteristics of Computer Networks: Fault Tolerance, Scalability, Quality of Service (QoS), and Security. Now let us understand them one by one.

Computer networks are a system of interconnected computers and other devices that allow for the sharing of information and resources. They can range in size from a few connected devices in a small office to millions of devices spread out across the globe. Here are some of the basic characteristics of computer networks:

 1.  Connectivity: The primary purpose of a computer network is to enable devices to communicate with each other. Connectivity is established through a variety of wired and wireless technologies, such as Ethernet cables, Wi-Fi, and Bluetooth.

 2.  Scalability: Computer networks must be scalable to accommodate growth and changing needs. As the number of devices and users on the network increases, the network must be able to handle the additional traffic and data.

3.   Security: Computer networks are vulnerable to security threats such as hacking, viruses, and data breaches. Security measures such as               firewalls, encryption, and user authentication are essential to protect network resources and data.

 4.  Reliability: Computer networks must be reliable to ensure that data and resources are always available when needed. Redundancy and                  backup systems can help to ensure that the network remains operational in the event of a failure.

 5.  Performance: The performance of a computer network is determined by factors such as bandwidth, latency, and throughput. These factors             affect the speed and responsiveness of the network and can impact the user experience.

 6.  Standards and protocols: Computer networks rely on standards and protocols to ensure that devices can communicate with each other.                 Standards such as TCP/IP and Ethernet, and protocols such as HTTP and SMTP, are used to ensure interoperability between devices and             networks.

7.   Management and administration: Computer networks require ongoing management and administration to ensure that they continue to                 function properly. This includes tasks such as monitoring network performance, configuring devices, and troubleshooting issues.

 Computer networks are essential for enabling communication and resource sharing between devices and users. They must be scalable, secure, reliable, and performant, and rely on standards and protocols to ensure interoperability. Effective management and administration are also critical to ensuring the ongoing operation and maintenance of the network..
