COMPUTER NETWORKS : CHAPTER 1


COMPUTER NETWORKS

Hello guys , This is kumar sourav. I m writing my first post and i will be concentrating on computer networks as you gonna need it in long run. I will write these in different chapters , and i will focus mainly on CISCO routers , switches and hubs .

Anyway thanks a lot to HACK WITH STYLE and XEO HACKER .
Now we start.There is mainly two types of hacking :
  • System hacking
  • Network hacking 
For network hacking you gonna need sound knowledge of computer networks.According to wiki A computer network, often simply referred to as a network, is a collection of computers and devices interconnected by communications channels that facilitate communications and allows sharing of resources and information among interconnected devices.
Or as i say this is a collection of devices which can communicate with each other
There are 4 types of networks
  1. Local area network 
  2. Metropolitan area network 
  3. Wide area network 
  4. Wireless networks (both LANs & WANs)
    • LOCAL AREA NETWORKS : these networks are relatively small networks and is generally implemented in a building . 
    • METROPOLITAN AREA NETWORKS : these are larger networks than LAN . these are generally implemented in a city or in a town. 
    • WIDE AREA NETWORKS : these networks cover a big area , you can say internet is also a WAN. 
    • WIRELESS NETWORKS : these are wireless networks which consists of both LAN & WAN.
    M gonna focus on LAN for some days.
    as this is my first post , m not gonna make it long so i stop here. But in next chapters onwards m gonna discuss a lot !!!
    THANK YOU
