What is a Network and Why is it Important?

Today, the internet and digital communication have become central to our lives. However, no matter how fast the digital world grows, it all fundamentally connects through networks. So, what is a network and why is it so important?

Definition of a Network

A network is a structure that allows multiple computers, devices, or systems to connect and exchange data. Networks enable independent devices to come together, share information, and provide services to each other. These connections can be wired or wireless.

Types of Networks

Networks can be categorized based on their usage. The main types of networks are:

LAN (Local Area Network): These are local networks that typically connect devices within a single building or campus. They provide fast data transfer and are usually cost-effective.

WAN (Wide Area Network): These are networks that cover a large geographical area. The internet is the largest example of a WAN, enabling global data transmission.

MAN (Metropolitan Area Network): These are networks that connect different points within a city or between cities.

Importance of Networks

Networks play many critical roles in modern life. In both business and individual use, networks are essential for functions like information sharing, communication, data storage and access, and security.

Especially today, with cloud technologies and IoT (Internet of Things), the importance of networks has grown even further. From devices in our homes to large data centers in workplaces, everything is connected through a network.
