Protocols that power the Internet.

What are Network Protocols?

The internet needs certain ways in order for data to travel from one place to another. Different protocols are
used for devices in the internet to communicate with each other in order to transmit data. Network protocols
are practically the rules of the internet. For example, if you want to search something up, you go to the browser
and type in the query. When the search starts, protocols are in use in order to find this information.

IP addresses

Internet Protocols, or IPs, are addresses that are given to devices as soon as they connect to the internet.
They are needed in order for devices to find each other and send data to and fro. IPs were also the first
protocols created along side TCP, or tranfer control protocol. Transfer control protocol is the protocol that
makes the data travel to and from different ip addresses.

List of common Protocols

  • HTTP - Hyper text transfer protocol
  • DNS - Domain name system
  • FTP - File transfer protocol
  • SMTP - Simple mail transport protocol
  • ARP - Address resolution protocol

OSI Model

  1. Physical Layer - Cables, wiring, etc.
  2. Data Link Layer - Data links through nodes. Nodes are where data is sent or collected.
  3. Network Layer - This layer is for finding the address to where the data is being sent.
  4. Transport Layer - Transportation of data to get to the address, like TCP.
  5. Session Layer - Reguates the connection between computers.
  6. Presentation Layer - Tranlation of the data to make it understandable to the human eye.
  7. Application Layer - This layer is for connection between web browsers and devices used be the user.
    HTTP, DNS, etc.
