Q:

What are disadvantages of TCP/IP?

A:

Quick Answer

The disadvantages of TCP/IP, or Transmission Control Protocol/Internet Protocol, are its size and its speed. Because TCP/IP is built for wide-area networks, its size can be an issue in small networks with limited resources, explains USENIX. Because TCP/IP runs several layers concurrently, it can slow down network speeds.

In very small networks with legacy equipment and little bandwidth, using TCP/IP can cause performance issues with hardware and throughput. TCP/IP connects large networks over distance, so developers focused on reinforcing reliability during data transmission. For instance, TCP/IP runs checksums on data during transmission. In smaller networks and some intranets, this can cause machine lag due to demands on memory and eat up bandwidth.

In addition, TCP/IP runs in layers – network interface, Internet, host to host, application – that handle different kinds of tasks simultaneously, explains the Knowledge Systems Institute. Although it is configurable, TCP/IP may sacrifice speed to networking bells and whistles over a small network. While large networks need separate proctocols to handle intranet versus Internet traffic and have more bandwidth to accomplish these tasks, small networks may need only reliable saves to mass storage. Although doing so is less secure, using a smaller protocol that checksums data only at the beginning and ends of transmissions, for instance, improves network speed and conserves bandwidth.

  • Q:

    What is the purpose of TCP/IP?

    A:

    The purpose of TCP/IP is to make it easier for computers to communicate with one another to send information over the Internet. It is a set of protocols that computers use so that they essentially speak the same language when passing information.

  • Q:

    What is the importance of TCP/IP?

    A:

    Transmission Control Protocol (TCP) and Internet Protocol (IP) are the two most important lower-level protocols enabling Internet connectivity. IP is responsible for moving packets of data from one connection point to the next, while TCP verifies the integrity of data traveling between two endpoints. TCP and IP work together so much that the two protocols are commonly referred to as TCP/IP.

    On what levels of the OSI model does the TCP/IP function?

    A:

    On the Open Systems Interconnection, OSI, reference model, the Internet Protocol, IP, resides on layer three, which is called the Network layer. The Transport Control Protocol, TCP, resides on layer four, which is called the Transport layer. The OSI reference model has seven layers that are divided into two groups called the upper layers and the lower layers.
