What is a network? The way of working created by using multiple computers interconnected is called a computer network. There are many computers in a computer network.These computers can be two computers standing side by side or there can be thousands of computers spread all over the world. Computers in the network are arranged in a certain way.
A cable connection is usually provided between computers. In cases where cable connection is not possible, communication within the network is established through microwaves and satellites.A computer connected to the computer network is in contact with other computers. It communicates with other computers, accesses data on their hard disk, and takes advantage of their programs.
Why Computer Networks Are Developed
The most important task of a network is to communicate between users. It allows users to take advantage of each other's computer resources. These resources can be a printer, driver, or hard drive. For example, accessing a data file on the other computer's hard drive and using it. advanced computer networks allow all of the computer systems of different capacities, consisting of personal computers, mime, and large computers, to be connected.
Typical benefits with a network environment:
• Sharing of programs and files
• Sharing of network resources
•Electronic mail
• Creating a working group
•Central management
•Security
• To increase the use of personal computers economically.
Sharing programs and files: Receiving network adaptations of many programs will always be more economical than purchasing that program separately. For example, instead of buying one database program for five different computers in an office, taking a program to the host of the network and using it by other users. Thanks to the network, users are in all programs.What is Network Technologies?Do you have a basic router and modem knowledge? Would you like to deepen the networking area more, but need to learn more technical skills? The growing area of network technologies offers businesses and institutions great opportunities for digital data transfer via information systems.
General View on Network
Network technologies allow for data exchange between large and small information systems primarily used by businesses and educational institutions. Network technicians, also known as network engineers or experts at companies such as Cisco, Microsoft, or SYSNETTECH Solutions, are responsible for configuring, installing, and troubleshooting the technology used to transmit digital information, audio, visual and data files. Through the network, end users can transmit files, messages and other data via e-mail or various other channels, sharing information over the Internet or Intranet connections, depending on the organization's needs.The development of a network includes evaluating an organization's administrative and information needs and evaluating hardware, installation, training, security, and account management costs. When a network is deployed, network technicians are often responsible for ensuring that the network remains operational and updated as needed. They usually provide technical support to company employees for problems that may arise.Network Technologies TypesA network consists of two or more computers connected to share resources (such as printers and CDs), exchange files, or allow electronic communication. Computers on the network can be connected by cables, telephone lines, radio waves, satellites or infrared rays of light.3G Network Technologies3G, the third generation short form, is the third generation UMTS (universal mobile telecommunications technology). Also known as HSPA or HSPA +, it offers convenient link speeds and bandwidth to power a wide variety of applications.4G Network TechnologiesIt is the fourth-generation mobile technology and provides mobile networks with higher speed and bandwidth. Also known as "LTE" (Long Term Evolution), 4G reveals the true potential of the cellular network and enables new applications that were not previously available in 3G.5G Network TechnologiesIt is the fifth generation mobile technology that is not yet available but is currently under development and testing. To meet the expanding network demands of technologies such as 5G, the Internet of Things, it will offer higher capacity than any network previously, it will be faster, more efficient and more cost-effective.AAAAuthentication, authorization, and accounting (AAA) is a framework to intelligently control access to computer resources, control usage, enforce policies, and provide the information needed for billing services.
