So guys!!!! here i am after a loooong time…but now you’ll be getting daily updates. ok now..lets start from where we left last..  IP ADDRESS In last class we have seen the classes of IP addresses. 5 classes are there out of which 3 are important and used in today’s scenario , these are A, B and C. Class A : 0.0.0.0 to 127.255.255.255 and subnet mask is /8 Class B : 128.0.0.0 to 191.255.255.255 and subnet mask is /16 Class C : 192.0.0.0 to 223.255.255.255 and subnet mask is /24 so thats lil bit revision about what we studied in the last post.Today we will be talking about Hackers. interesting nah..?? yeah it is pretty much ..who are they and what they do.. A hacker is one who enjoys the intellectual challenge of creatively overcoming and circumventing limitations of programming systems and who tries to extend their capabilities.The act of engaging in activities (such as programming or other media) in a spirit of playfulness and exploration is termed...

Internet Protocol hierarchy contains several classes of IP Addresses to be used efficiently in various situations as per the requirement of hosts per network. Broadly, the IPv4 Addressing system is divided into five classes of IP Addresses. All the five classes are identified by the first octet of IP Address. Internet Corporation for Assigned Names and Numbers is responsible for assigning IP addresses. The first octet referred here is the left most of all. The octets numbered as follows depicting dotted decimal notation of IP Address: The number of networks and the number of hosts per class can be derived by this formula: When calculating hosts’ IP addresses, 2 IP addresses are decreased because they cannot be assigned to hosts, i.e. the first IP of a network is network number and the last IP is reserved for Broadcast IP. Class A Address The first bit of the first octet is always set to 0 (zero). Thus the first octet ranges from 1 – 127, i.e. Class A addresse...

W hat is IP? “ The Internet Protocol  ( IP ) is the principal communications  protocol  in the  Internet protocol  suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the  Internet”. ——-this is what THE WIKIPEDIA SAYS .. but guys.. frankly speaking, i never got it when i first searched for IP on the INTERNET. so for those who are facing the same difficulty, i have a simple and understanding definition.. here we go… As we all have our house’s address to have a particular identification and someone want to reach to you can come to your address and do his job. similarly this happens in case of INTERNET. If we want to open a website or to connect to some other computer which is not around us then something that recognises our requirement and divert us to that place is INTERNET PROTOCOL or IP.  But now the biggest question is that we open any website by the...
