Netiquettes Cyber Law
A network is a group of devices connected to each other to share data and resources. The Internet
is a vast global network that allows communication and access to information across the world.
With the rise of online activities, it is important to understand terms like spam, malware, and
cyber threats, and use security measures such as antivirus software, firewalls, and safe browsing
practices to protect personal data.
WHAT IS A NETWORK?
A network is a collection of devices, such as
computers, printers, and smartphones, that are
connected together in order to share resources,
information, and communicate with each other.
These devices are linked by cables, radio waves,
or satellites, enabling them to exchange data over
long or short distances. In simple terms, a network
allows multiple devices to work together, share
files, access the Internet, and print documents from any device within the same network.
Networks can be found everywhere, from home networks where people connect their computers
and smart devices, to large corporate networks that connect thousands of machines across the
globe.
Different Types of Networks
There are various types of networks, each designed to suit different purposes, depending on the
size, location, and scope of connectivity required.
