computer networks and networking concepts
Answers
How do I learn Computer Networking in an effective and practical way?
Computer networking is very easy to learn, but you have to follow some path in order to learn about networking.
Below are some of the playlist to learn about networking fundamentals:
All the above tutorial gives you a Basic idea about networking and why networking is important in the 21st Century.
Now comes to the practical part of networking, Cisco packet tracer and GNS3 are two networking simulator that allows us to do practical part of networking.
follow these tutorials:
There are lots of certification in networking like CCNA, CCNP, CCIE and these certification are best in the industry .
All the above links are free but there are also some paid website where you will find good info about certification course:
Best of luck :)

Is this answer still relevant and up to date?
My suggestion is.. Don't start with reference books. TCP/IP, networking has come into existence long back and many authors, bloggers, researchers have put everything in simple terms which are all available in internet.
I can give one example:
The author puts everything in fun way and skips of all complicated parts and just gives references. If you start with such books and such guides, you will develop interest and understanding using which latter you can go for reference books and in-depth study.
Follow these steps
1. Search for a topic on google. e.g., TCP/IP or firewall or DNS or HTTP
2. See various links presented. Skip off the ones that has too much technical details during initial study.
3. Read the pages which explain things in little simpler terms, some like "How stuff works" kind of pages.
4. Once you understood the concept and saw some practical applications of it, then go for technical details.
We have lot of knowledge around in the internet my friend, only you need to chose wisely and grasp the concepts.
Computer network
In basic terms, computer network is a type of network that allows computers to communicate with other computers via medium. There are mainly 3 types of network: WAN , LAN and MAN.
WAN - Wide Area Network
Wide area network is provided for large geographical areas like schools, offices, colleges and institutions. WAN is established with the least telecommunication circuits. WAN is used to transmit data and information at large distance.
- Most of the private WAN networks uses 24 Bit block for communication service.
- Circuit-switched telephone lines, radio wave transmission, and optical fiber are some of the technologies used in Wide Area Network.
- WAN provides us High speed internet upto 400 gigabit. AT&T has successfully launched their broadband WAN service to provide high speed internet.
LAN - Local Area Network
Local Area Network interconnects the computers at small geographical area such as schools and colleges. Ethernet and Wi-Fi are the two common technologies used in Land Area Network. In this type of network, Cabling is a common technology that is used for interconnecting two different computers.
- Local Area Network was created in 1960 by the students of university.
- LAN provides high speed internet using Ethernet cables. Ethernet cables data is later converted in wireless network using routers.
- Wireless media is a common thing nowadays. Today, every smartphone, tablet and desktop have built in wifi connection, which helps to use internet without Ethernet cables wireless.
- NetBEUI, IPX/SPX, AppleTalk are the protocols used in Local Area network for data communication.
MAN - Metropolitan Area Network
MAN is a type of network that covers very high Geographical areas like districts, towns and villages. The MAN network is transmitted through the tower in the form of waves, when this waves enters in our smartphone, they are later interrupted by our smartphone and hence we can use it.
- Metropolitan Area Network is also called as Wide Area Network (WAN)
- MAN network is used since 1994 for data communications.
- This network is provided from ISP to city and from towers, this network is later converted into waves.
- Business, education and government entities uses Metropolitan Area Network.
