Firewall

                  A  firewall  is  a  security  system  that  monitors  and  controls
                  incoming  and  outgoing  network  traffic.  It  acts  as  a  barrier
                  between  a  trusted  internal  network  and  untrusted  external
                  networks, like the Internet. By filtering traffic and preventing
                  unauthorised access to a system, a firewall helps to ensure
                  that malicious entities cannot enter your network and steal or
                  corrupt your data.

                     NETIQUETTES

                  Netiquette refers to the accepted social behaviours and guidelines for interacting with others on
                  the Internet. Just as in face-to-face communication, it is important to be respectful, polite, and
                  considerate when communicating online. This includes not posting offensive content, respecting
                  others' privacy, and avoiding harmful behaviours like cyber bullying and trolling.
                  Some basic netiquettes are:

                     Treat others online with respect, just like in person.
                     Don’t share personal information and introduce yourself before chatting.
                     Use correct spelling and grammar, and avoid all caps.

                     Respect privacy, credit original creators, and follow community rules.
                     Be open-minded, and report abusive behaviour to protect yourself and others.

                     CYBER LAW

                  Cyber law refers to the legal regulations and laws that govern activities on the Internet. It covers
                  a wide range of issues, including privacy, data protection, cybercrime, intellectual property, and
                  online contracts. With the rise of Internet usage, cyber laws are becoming increasingly important
                  for protecting both individuals and businesses from online threats.
                  In conclusion, the Internet is a powerful tool that connects people and devices across the world,
                  but it also comes with risks. Understanding the various types of networks, being aware of online
                  threats like malware and phishing, and using protective measures like firewalls, antivirus software,
                  and strong passwords can help ensure a safer online experience. Respecting others through
                  netiquette and understanding cyber laws are also key elements of responsible Internet use.
                  Cyber law: Indian IT Act 2000

                  The Indian IT Act 2000 (Information Technology Act, 2000) is the primary law governing cyber
                  activities in India. It was enacted to facilitate electronic commerce, ensure the legal recognition
                  of electronic transactions, and address cybercrimes. The Act covers a broad range of issues,

                  including the legal validity of electronic  records, digital signatures,  and  electronic  contracts,
                  helping to promote the growth of online businesses and secure transactions.
                  Some key provisions of the IT Act are as follows:
