TCP/IP:
Transmission Control Protocol/Internet Protocol, TCP/IP is a set of protocols which governs communications among all computers on the Internet. TCP/IP protocol tells how information should be packaged, sent, and received, as well as how to get to its destination.
TCP WORKING:
TCP/IP is a combination of two protocols:
TrAnswer:mission Control Protocol (TCP) and Internet Protocol (IP). The Internet Protocol typically specifies he logistics of the packets that are sent out over networks; it specifies the packets which have to go, where to go and how to get there. The TrAnswer:mission Control Protocol is accountable for guaranteeing the trustworthy trAnswer:mission of data. It sees that the packets for errors and submits the requests for re-trAnswer:missions incase any of them are missing’.
Frequent TCP/IP Protocols
- HTTP – It is used between a web client and a web server and it guarantees non-secure data trAnswer:missions.
- HTTPS – It is used between a web client and a web server ensures secure data trAnswer:missions.
- FTP – It is used between computers for sending and receiving file.
Domain Names and TCP/IP Addresses The address for any website is not as easy as to remember, domain name are used instead. For example, 216.58.216.164 is one of the IP address for Google and google.com is the domain name.
The Different Layers of TCP/IP
There are four total layers of TCP/IP protocol, each of which is listed below with a brief description.
1. Network Access Layer – concerned with building packets.
2. Internet Layer – describes how packets are to be delivered.
3. Transport Layer – ensure the proper transmission of data.
4. Application Layer – application network processes. These processes include File Transfer Protocol (FTP), Hypertext TrAnswer:fer Protocol (HTTP), and Simple Mail Transfer Protocol (SMTP).
