Hello readers, and MERRY CHRISTMAS to all of you. If you want to become a hacker then you must have good knowledge of Networking and your basics should be crystal clear. That's exactly is what we are going to explore today.
So, first of all - What is networking? Well, Networking is connecting devices together so that they can communicate with each other, in order to share data, files, and other computing resources. It happens all around us from PCs to ATMs and cell phones.
Basically there are three types of network :-
1.LAN or Local Area Network : The computer network covering a small physical area, like a home, office, or small groups of buildings, such as a school, or an airport. Main features being higher data transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines.
2.WAN or Wide Area Network : The computer network that covers a broad area i.e., any network whose communications links cross metropolitan, regional, or national boundaries. This is in contrast with personal area networks(PANs), local area network(LANs), campus area networks(CANs), or metropolitan area networks(MANs) which are limited to a room, building, campus or specific metropolitan area(e.g., a city) respectively.
3.WLAN or Wireless Local Area Network : The network that links two or more networking devices using some wireless distribution method (typically spread-spectrum or OFDM radio) and usually providing a connection through an access point to the wider internet. This gives users the mobility to move around within a local coverage area and still be connected to the network.
Common Networking Devices include Hub. Switch, Router and Wireless Access Point.
Since we are talking about networking, let me throw some light on the terms Internet and Intranet because mostly people are confused between the two and often consider them alike. Internet is a global system of interconnected computer systems that use the standard Internet Protocol Suite(TCP/IP) to serve billions of users worldwide.It is a network of networks. Whereas Intranet is a private computer network that uses Internet Protocol technologies to securely share any part of an organisation's information or other resources within that organisation. The term is used in contrast to internet, a network between organisations, and instead refers to a network within an organisation.
That's all for today, and once again MERRY CHRISTMAS!!!
