What is the TCP/IP Model?
TCP/IP Model helps you to determine how a specific computer should be connected to the internet and how data should be transmitted between them. It helps you to create a virtual network when multiple computer networks are connected together. The purpose of TCP/IP model is to allow communication over large distances.
TCP/IP stands for Transmission Control Protocol/ Internet Protocol. It is specifically designed as a model to offer highly reliable and end-to-end byte stream over an unreliable internetwork.
TCP Characteristics:
Here, are the essential characteristics of TCP/IP protocol
  • Support for a flexible architecture
  • Adding more system to a network is easy.
  • In TCP/IP, the network remains intact until the source, and destination machines were functioning properly.
  • TCP is a connection-oriented protocol.
  • TCP offers reliability and ensures that data which arrives out of sequence should put back into order.
The functionality of the TCP/IP model is divided into four layers, and each includes specific protocols.
TCP/IP is a layered server architecture system in which each layer is defined according to a specific function to perform. All these four layers work collaboratively to transmit the data from one layer to another.
  • Application Layer
  • Transport Layer
  • Internet Layer
  • Network Interface




Advantages of TCP/IP
Here, are pros/benefits of using the TCP/IP model:
  • It helps you to establish/set up a connection between different types of computers.
  • It operates independently of the operating system.
  • It supports many routing-protocols.
  • It enables the internetworking between the organizations.
  • TCP/IP model has a highly scalable client-server architecture.
  • It can be operated independently.
  • Supports a number of routing protocols.
  • It can be used to establish a connection between two computers.
Disadvantages of TCP/IP
Here, are few drawbacks of using the TCP/IP model:
  • TCP/IP is a complicated model to set up and manage.
  • The shallow/overhead of TCP/IP is higher-than IPX (Internetwork Packet Exchange).
  • In this, model the transport layer does not guarantee delivery of packets.
  • Replacing protocol in TCP/IP is not easy.

  • It has no clear separation from its services, interfaces, and protocols.

But people today call it by various names - adventuresome (to start something different from others), risk taking, thrill seeking (much of up’s and down’s), innovating (something new). Hence the word entrepreneurship in today’s concept can be called an event of adventuresome which takes risks, seeks thrills and innovative.

MARWARI COLLEGE,RANCHI (UNDER RANCHI UNIVERSITY,RANCHI) NAME : RAJU MANJHI SUB: EDP SEM: VI(CA/IT/CM) ______________________________________________________________________________ Identification of business opportunities.

Benefits of Using Proxy Servers 1. Your IP Address Is Hidden One of the best proxy server advantages – by using a proxy, the website you access will not be able to log your real IP address, as it will log the proxy server’s IP address instead. Yes, that means you’re somewhat anonymous when you browse online. D on’t forget –   your IP address   ca n tell someone a lot about yourself, like what country and city you are from. Crafty cyber criminals can even go the extra mile and use your IP address to find out things like who your ISP is, what your zip code is, and even what street you live on.   How would a hacker get access to your IP address, you ask? Sadly, a data breach or leak on a website you visit could be enough for them to get their hands on this info. So, something like this is definitely useful nowadays. 2. You Can Access Geo-Blocked or Restricted Content Unfortunately, a lot of online content is actually hidden behind  geo-restrictions  – mostly because of net
