Concept of Voice over Internet Protocol (VoIP) Voice over Internet Protocol‚ commonly known as VoIP‚ is a technology used for the transmission of voice information using the Internet Protocol (IP). VoIP allows the sending of voice information in a digital form using packets as opposed to the traditional circuit-committed protocols of the Public Switched Telephone network (PSTN). Traditionally when one wishes to make a phone call‚ a call is placed using a telephone that is connected to a circuit-switched

Basic synchronous systems will synchronize both clocks before transmission begins‚ and reset their numeric counters for errors etc. More advanced systems may negotiate things like error correction and compression. 2 ASYNCHRONOUS Asynchronous communication utilizes a transmitter‚ a receiver and a wire

TCP/ IP In information technology‚ a protocol is a special set of rules or instructions that end points in a telecommunication connection use when they communicate. In the context of data communication between two points‚ a network protocol can also be referred as a formal set of rules‚ conventions and data structure that governs over how computers and other network devices exchange information over a network. From that‚ we can understand that a protocol is a standard procedure and format that two

TCP refers to Transmission Control Protocol. OSI refers to Open Systems Interconnection. Model TCP/IP is developed on points toward a model the internet. TCP/IP has 4 layers. OSI has 7 layers. TCP/IP more reliable than OSI OSI has strict boundaries; TCP/IP does not have very strict boundaries. TCP/IP follow

Abstract Transmission Control Protocol (TCP) is the utmost universally protocol that is used on the Internet. The cause on behalf of this is that TCP gives fault rectification. An assurance of conveyance is tantamount with TCP. While IP takes care of handling the actual delivery of the data‚ TCP takes care of keeping track of the individual units of data‚ “called packets” that a message is divided into four efficient routing through the Internet. This is accredited fundamentally in reference to
Premium Transmission Control Protocol Internet Protocol User Datagram Protocol
There are differences between the User Datagram Protocol (UDP) and the Transmission Control Protocol (TCP). Looking at UDP this protocol is unreliable and does not create a connection to the summoning application. TCP however does provide a reliable connection. This protocol also has an added bonus where any errors that are found during transmission will be retransmitted‚ which means that this protocol endeavours to make error checks (Kurose J‚ Ross K‚ 2013). Most of the traffic that is carried over
