In the application layer, an application, such as an internet browser, gets the data and a user can then interact with it. The presentation layer is where data gets encrypted and decrypted and converted into a form that is accessible by the application layer, Bluetooth and USB are another popular data link layer protocols used in computer networks. Wi-Fi is defined with IEEE 802.11 standard. Wi-Fi is another popular protocol that is mostly used for laptops, tablets, smartphones, TVs to connect to LAN devices wireless. The session layer has a connection that manages the sessions happening between applications. Ethernet is defined with IEEE 802.3 standard. In the transport layer, the data hops between different points on the network on its way to its destination. In the network layer, the data gets its address and routing instructions in preparation for its journey across the network. The datalink layer is the point-to-point connection that transmits the data to the network layer. This consists of a data connection between a device generating data and the network. Both provide data communication services, enabling users to send and receive information from their IP address using the services made available by their internet service provider (ISP). OSI discussion, there are more similarities between the OSI and TCP/IP models than differences. Although both the TCP/IP and OSI models transport data, the ways they send it are slightly different, which is sometimes why TCP/IP is used instead of OSI. The biggest difference between the OSI and TCP/IP models is the OSI model has seven layers instead of five. The OSI model is another way of transmitting data over the internet. For example, the IEEE 802.3 protocol is used to convert data into what is used in an Ethernet connection. On the hardware layer, the data is turned into something that can be sent to and read by a computer or other device. At the network interface layer, the packet of data gets formatted and prepared to be transported and routed through the network. This information is then conveyed to the network interface layer. In the network access layer, the data gets a header and a trailer, and these tell the data where to go. In the transport layer, the data gets encoded so it can be transported through the internet using either the User Datagram Protocol (UDP) or TCP. A web browser, for example, is used to generate the data that gets sent through the rest of the layers, assisted by the Domain Name System (DNS), which associates web domain names with their Internet Protocol (IP) addresses. Bluetooth is less secure as compared to Wifi and uses encryption and authentication keys. Power consumption is low in Bluetooth, while it is high in Wifi. Applications are used to create the data. On the contrary, in Wifi the frequency range is 2.4 GHz and 5 GHz. The application layer is where data originates on the sender’s side. Here is a breakdown of what each layer in the TCP/IP model does: In other words, in the TCP/IP model, these services are all done in the application layer. In TCP/IP, this provides users with the physical standards, transport functions, network interface, and internetworking functions that correspond with the first three layers of the OSI model. This may look drastically different from the OSI model, primarily because some functions are encompassed in a single layer: the application layer. Means it makes use of light waves to deliver data. LiFi is a wireless communication technology which uses light to transmit data rather than radio frequencies like bluetooth. Light Fidelity (LiFi): LiFi stands for Light Fidelity. In contrast, Wifi has better security, although still there are some security issues.

It is more complex and requires configuration of hardware and software.ġ50ms - Average Latency.The Transmission Control Protocol/Internet Protocol (TCP/IP) model came before the Open Systems Interconnection (OSI) model, and it has five layers: The range and transmission speeds of bluetooth are typically lower than Wi-Fi. On the contrary, in Wifi the frequency range is 2.4 GHz and 5 GHz. It is easy to switch between devices or find and connect to any device. Can be used to connect upto seven devices at a time. Antennas can also increase range.įairly simple to use. 2.5GHz Wi-Fi communication has greater range than 5GHz. With 802.11b/g the typical range is 32 meters indoors and 95 meters (300 ft) outdoors.
