Computer systems have been handling data since decades, but the volume and speed of handling has become phenomenal in the last few years. Data processing means "the collection and manipulation of items of data to produce meaningful information", has been evolving in terms of speed, efficiency, and leveraging the computing resources, till date. In this article, we will see two important techniques of data processing in the field of computation − Batch processing and Stream processing. We will elaborate them in detail and see how they are different. What is Batch Processing? Batch processing is technique of processing large amount ... Read More

Data transmission has been crucial in the age of digital communication. Either digital or analogue data can be transmitted over a communication medium to one or more devices, depending on the interfaces in use. There are two important types of data transmission − Baseband and Broadband. Read through this article to understand each type of transmission and the differences between them. What is Baseband Transmission? It is a transmission technology where a single signal is either sent or received through a communication channel such as a cable, in the form of discrete pulses of the single frequency. The frequency of ... Read More

When a network is being designed, the "network switch" that is employed is considered to be the "brain" of the network. The networking hardware ensures that all of the devices remain linked to one another at all times. Therefore, it is essential to select and set up an ideal network switch.Switches can vary in both their physical dimensions and the number of ports that they offer. They can have a maximum of forty-eight ports between them. Two of the most prevalent types of switches are managed and unmanaged switches.What is a Managed Switch?Managed switches are famous for their redundancy, in ... Read More

A gateway is a piece of networking hardware or a network node that allows two separate networks to communicate with one another. Computers and routers are the most typical gateways that can connect a company to the internet. A firewall is a network security system that determines which data packets are allowed to access the network.Read through this article to find out how Gateways are different from Firewalls.What is a Gateway?A gateway is a network hardware device, sometimes known as a network node, that establishes a connection between a host network and a remote network. Because the gateway serves as ... Read More

What is a Content Delivery Network?A Content Delivery Network (CDN) is a collection of computers that keep data copies at several network nodes. A well-designed and adequately executed CDN increases data access by increasing bandwidth and reducing access latency. Web objects, apps, database queries, downloadable data objects, and video streams are all examples of CDN content.A CDN is a collection of computer nodes connected over the Internet to give users access to massive volumes of video or data. CDNs are also known as Content Distribution Networks.A CDN architecture comprises numerous independent components that all work together to give service to ... Read More

The network topology is a structure or the physical arrangement of the network devices, how the components of the network are interconnected with each other.Types of network topology are as followsBusStarRingMeshHybridLogical TopologyIt tells about a network that should be configured for the transfer of information. This is different from physical topology as it does not explain the physical wiring of a network, but instead, it describes the flow of data, information, and back, from one system to another and the routes it takes.Some examples of Logical topology are as follows −Logical Star Topology − Uses logical bus topology to transfer ...

Campus Area Network (CAN) is also called a corporate area network and it helps to like LAN with small geographical space. The main objective is offering the best accessibility of campus residential regions like schools, colleges, university, small institutes (Campus), and corporate area (building). It is larger than LAN but small than WAN and MAN networksIt can cover many buildings in an area. Here all computers are connected together and have some relationship to each other.For example − Different buildings in a campus are connected using Campus Area Network (CAN) they help to interconnect departments, library and computer laboratories.Given below ...

To begin with, let us learn the concepts of data protection and data privacy.Data ProtectionData protection is inclusive of the strategies that we can use to secure the privacy, availability, and integrity of our data. It is also called data security or information privacy.Data protection is important for any organization which collects, handles, or stores sensitive data. This strategy can help prevent data loss, theft, or corruption and can help minimize damage caused by disaster.Data PrivacyData privacy is defined as only the authorised person can access the data. It is typically applied to personal health information (PHI), personally identifiable information ... Read More

The full form of ISCII is Indian Script Code for Information Interchange. It was established as Bureau of Indian Standards in 1991 and it is based on an earlier Indian Standard IS 10401:1982. It is a type of coding scheme for Indian languages.It is an 8-bit standard where lower 128 characters (0-127) conform to ASCII standard and higher 128 characters (128-255) are used to encode characters from an Indian script.ISCII encoding strategy is used in Unicode in their encoding. Generally the characters of the Indian language derive from the ancient Brahmi script. Mostly all the characters resemble closely to each ... Read More
