Benefits of Computer networking in modern civilization

Computer networking is a feature of today’s technology that greatly impacts the economy. It plays a role, in helping businesses operate efficiently and expand their reach to customers worldwide. Additionally, it fosters communication and collaboration among researchers and educators leading to groundbreaking discoveries and advancements. In our lives networking has become indispensable, for staying connected with loved ones shopping online and enjoying our TV shows. Likewise in the workplace networking enables us to access files and applications collaborate effectively with colleagues and engage with customers in a manner.

What is networking?

The practise of joining two or more computers so they may exchange resources and communicate with one another is known as computer networking. Numerous media, such as wires, cables, radio waves, and infrared light, can be used for this. The area of computer science known as computer networking is concerned with the design, construction, upkeep, and security of computer networks. It combines telecommunication, computer science, and computer engineering.

The technology which is used to exchange the data between small and large information. This technology can be used in educational institutions as well as businesses. Network technicians know the installation; configuration & troubleshooting of the network technology and this can be used to send digital data like audio, data and visual files. By using networking, users can send messages, files through e-mail or other channels based on the organization’s requirement.

Here are Two types of computer networks. 

LAN - A LAN refers to a computer network that comprises access points, cables, routers and switches. Its purpose is to facilitate the connection of devices, to web servers and internal servers within a building, campus, or home network. On a LAN devices like computers and workstations can easily share files and access each other through an Internet connection.

LANs almost always use Ethernet, Wi-Fi. Ethernet is a protocol for physical network connections that requires the use of Ethernet cables. Wi-Fi is a protocol for connecting to a network via radio waves.


WAN - Wide-area network (WAN) is a collection of local-area networks (LANs) or other networks that communicate with one another.  A WAN is essentially a network of networks, with the Internet the world's largest WAN.

A big computer network spanning a great distance geographically is called a wide area network (WAN). WANs are frequently used to link institutions, enterprises, and organisations with various locations. They can also be utilised to establish connections amongst people who live in various parts of the globe.                                                                 

Difference between public and private networks.

Public and private networks are two distinct types of networks that differ in terms of ownership, access control, and security measures.

Public network - Anyone can access public networks and their resources and services without restriction. The internet, mobile data networks, and Wi-Fi hotspots in public areas are a few examples of public networks. Users of public networks can connect from any location with an internet-enabled device, making them convenient and flexible. Nevertheless, as data sent over a public network is susceptible to interception and possible misuse, this openness comes at the sacrifice of security.

Private network - Private networks, on the other hand, are restricted to authorized users, typically belonging to a specific organization or institution. Private networks include those found in homes, offices, and educational institutions. Passwords, encryption, and firewalls are examples of access control measures used by private networks to protect sensitive information and stop illegal access. Confidential information is safeguarded, and security is improved by this regulated environment.

The advantages of computer networking

Resource sharing - Computer networks allow for efficient sharing of resources such as printers, scanners, and storage devices. This eliminates the need for multiple copies of expensive hardware, reducing costs and maximizing resource utilization.

Improved communication and cooperation - Regardless of a group's or individual's geographical location, computer networks facilitate easy communication and cooperation between them. They enable remote access to information and resources, file sharing, video conferencing, and real-time messaging.

The disadvantages of computer networking

Cost -The setup and upkeep of a computer network can be costly. This covers labour, cabling, software, and hardware costs. There are also continuous expenses for upgrades, maintenance, and security.

Security - Malware, viruses, and hacking are just a few of the security risks that can affect computer networks. These dangers have the ability to corrupt or destroy data, steal private information, and interfere with network functions. 

In general, computer networks are necessary for our contemporary lifestyle. They give us access to resources, facilitate collaboration, communication, and information sharing that was previously unattainable. Computer network technology is always altering to adapt to consumers' and businesses' shifting needs. Emerging technologies like software-defined networking (SDN) and 5G are commonplace. In the years to come, these technologies have the potential to completely change the way we network.

Introduction to the essentials on Cybersecurity

Image
In the modern digital environment, the role of cybersecurity is now greater than it was before. Our computers, laptops and other devices contain various private and secure personal data, such as medical and financial records. Cybercriminals view this data like sweet honey and strive to steal it using increasingly sophisticated means. What is Cybersecurity? Computer security, also known as Cybersecurity or information security defines the measures used to deter unauthorized access, use, disclosure, modification, destruction, or disruption of computers and computer networks. This is a complicated and forever changing field  as cyber-criminals continuously come up with innovative methods of attack. While computer hardware is secured in the same way that sensitive equipment such as lockers and doors are protected, critical information and system access and authorization, on the other hand, are protected through complex security tactics and  practices. Why is Cybersecurity Imp...

  Google Classroom The Internet is the world's largest computer network. Let's break that down: A  computer network  is any group of interconnected computing devices capable of sending or receiving data. A  computing device  isn't just a computer—it's any device that can run a program, such as a tablet, phone, or smart sensor. Building a network The simplest computer network is two devices: A diagram of the simplest computer network. Two computers are shown with a line connecting them. A network like that only has to worry about a few things, like how to physically connect the two devices and how to send data over the physical connection in a format they both understand. Let's add one more device: A diagram of a simple computer network. Three computers are shown with a line from one computer to the next. Now there's additional complexity. How can each device know whether incoming data is meant for them or for their neighbor? This simple network will need an addr...
