What's that whole TCP/IP thing about?

TCP/IP (Transmission Control Protocol/Internet Protocol) is the essential correspondence dialect or convention of the Internet. It can likewise be utilized as an interchanges convention in a private system (either an intranet or an extranet). When you are set up with direct access to the Internet, your PC is furnished with a duplicate of the TCP/IP program similarly as each other PC that you may send messages to or get data from likewise has a duplicate of TCP/IP. 

TCP/IP is a two-layer program. The higher layer, Transmission Control Protocol, deals with the amassing of a message or document into littler parcels that are transmitted over the Internet and gotten by a TCP layer that reassembles the bundles into the first message. The lower layer, Internet Protocol, handles the address some portion of every bundle with the goal that it gets to the correct goal. Every portal PC on the system checks this deliver to see where to forward the message. Despite the fact that a few bundles from a similar message are steered uniquely in contrast to others, they'll be reassembled at the goal. 

Organizing has 7 layers (contingent upon who you converse with) of reflection that gap up the duties of each progression in getting data out of your PC and to another PC. 

Layer 1 is the physical layer, the genuine electrical handling piece. 

Layer 2 is the Data Link layer, this handles the Frames of information going out from your PC. This handles the movement between 2 hubs, your PC and the following PC 

Layer 3 is the Network Layer, This layer handles movement past 2 hubs. IP capacities at this layer, The information gone by this layer is called "bundles". Even for routers as you can access them through IP 192.168.1.1, provided you have the password (here's how to recover router password).

Layer 4 is the Transport Layer, This layer guarantees that the bundles get to where they need to go. It oversees division, reassembly and affirmation, TCP and UDP work at this layer. This layer utilizes ports so that the working frameworks can distinguish what benefit the activity approaching is bound for. For instance in case I'm heading off to a https site, my PC sends a demand to port 443. The server gets the movement and advances the information it gets to the product in the following layer that is tuning in on 443. 

I could go on and portray the others, however that basically aggregates up what TCP and IP are (however there are significantly more lumpy points of interest like bundle structure, and so forth, the subtle elements of a TCP handshake, and so on).
