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

Black Box Testing and Gray Box Testing are the two types of testing used to test a software which are based on feedback from real customers using real products in real environments, but they are driven by distinct goals and processes. In this article, we will discuss the major differences between black box testing and gray box testing by considering different parameters. But before that it is important know the basics of black box testing and gray box testing to understand the differences between them. What is Black Box Testing? A software testing technique that is used to check ... Read More

The main constituent of any database is its tables, in order to make data accessibility custom there is concept of Views in other words we can say that with the help of Views of a table we can restrict any user to access only that data which is supposed to be accessed by him. Now on the basis of characteristic and features of the views we can distinguish between Views and Materialized Views. In this article, we will discuss the important differences between Views and Materialized Views in SQL. But before, let’s have look into the basics of views and ... Read More
