SMTP and POP3 are message protocols which are required for sending and receiving the messages between the mail servers. In this article, we are going to compare and contrast the various features of SMTP and POP3 based on the tasks for which these two protocols have been designed. What is SMTP? The Simple Mail Transfer Protocol (SMTP) is an Internet communication protocol for sending and receiving electronic mail. SMTP is used to transmit and receive mail messages by mail servers and other message transfer agents. User-level email clients usually utilize SMTP exclusively to transmit messages to a mail server for ... Read More

Both Site-to-Site VPN and Remote Access VPN are types of virtual private networks used primarily for transferring data and accessing a machine from a remote location under a secure network which acts as a private network across the machines.In this article, we will differentiate Site-to-Site VPN and Remote Access VPN based on their features. Let's start with an overview of VPN and the role it plays.What is a VPN?A Virtual Private Network (VPN) connects users' computers to a private network across a public network, enabling them to receive and send data as if they were physically attached to the private ...

In communication systems, the data transfer between a sender and a receiver follows a particular mode which is also known as the "transmission mode". On the basis of the nature of data sent and received, we can categorize the Transmission modes as Simplex, Half−duplex, and Full−duplex. Read this article to find out more about these transmission modes and what sets them apart. Simplex Mode of Data Transmission In a data communication network, when there is a single movement of data or one control movement of data from the sender to the receiver, then it is called the Simplex mode of ...

The process of sending data between two or more digital devices is known as data transmission. Data is transmitted between digital devices using one of the two methods − serial transmission or parallel transmission.In serial transmission, data bits are sent one after the other across a single channel. Parallel data transmission distributes numerous data bits through various channels at the same time.What is Serial Transmission?A serial transmission transfers data one bit at a time, consecutively, via a communication channel or computer bus in telecommunication and data transmission. On the other hand, parallel communication delivers multiple bits as a single unit ... Read More

Both sequence diagrams and activity diagrams are commonly used in software engineering to model the interactions and flows within a system. They are also useful in other fields, such as business process modeling, to model and analyze the flow of activities or interactions within a business process. Read this article to find out more about sequence diagrams and activity diagrams and how they are different from each other. What is Sequence Diagram? A sequence diagram is a diagram in that is used in representing the sequence of messages flowing from one object to another. The main objective of a sequence ... Read More

Both Synchronous and Asynchronous Sequential Circuits are types of sequential circuits that use feedback for the next output generation. On the basis of the type of this feedback, both circuits can be differentiated. A sequential circuit is one whose output depends upon both present and past inputs. The classification of sequential circuits into synchronous and asynchronous sequential circuits is done on the basis of their triggering. In a synchronous sequential circuit, the changes in all the state variables are synchronized with the universal clock signal. In contrast, in an asynchronous sequential circuit, the changes in all the state variables are ... Read More

Both Virtual Circuits and Datagram Networks are the types of connection services which are used for transmission of information from a sender to a receiver. The most basic difference between the two is that the virtual circuits are connection oriented services that require resources like buffers, CPU, bandwidth, etc., for a data transfer session, while the datagram networks are connectionless services where no such resources are required for data transmission. There are many other key differences between virtual circuits and datagram networks, which we will discuss in this article. What are Virtual Circuits? Virtual Circuit is a connection oriented service ... Read More

In digital electronics, both combinational and sequential circuits are the most widely used circuits. These are two broad categories of circuits defined in the digital electronics where one type of circuit is independent of time and other is dependent on time. Read this article to find out more about combinational circuits and sequential circuits and how these two circuits are different from each other. Let's start with a basic overview of combinational and sequential circuits so that it becomes easier to understand how they are different from each other. What is a Combinational Circuit? A combinational circuit is one whose ... Read More

Both Client-Server and Peer-to-Peer networks transfer data from a source to a destination with minimal loss in transmission. Both these networks establish a communication channel through which data transmission takes place, however the channel remains dedicated in case of a Client-Server network, which is not the case with Peer-to-Peer networks.Read through this article to find out how client-server networks differ from peer-to-peer networks.What is a Client-Server Network?The client-server paradigm is a network process communication structure that connects service requestors, clients, and providers. A network or the Internet is used to connect the client and the server.The client-server approach, which also ... Read More

Circuit switching and Message switching are both telecommunication techniques that are used to transfer data from a source to a destination with minimal loss in transmission.Circuit switching is a way of constructing a dedicated network in which two network nodes create a dedicated communications channel before connecting. In message switching, the source and destination nodes are not connected; the intermediate nodes are in charge of data transfer.Read through this article to find out more about Circuit switching and Message switching and how they are different from each other.What is Circuit Switching?In circuit switching, networks create dedicated transmission channels. While other ... Read More
