How to use Net Meeting and what is the code to start and join the meeting online?
NetMeeting was Microsoft's pioneering video conferencing solution that came pre-installed with Windows 95 and Windows XP. This application provided basic video calling, desktop sharing, and collaborative features before being replaced by Windows Meeting Space in Windows Vista. While no longer supported, understanding NetMeeting helps appreciate the evolution of modern video conferencing tools. NetMeeting offered a simple, menu-driven interface that made it accessible to users with basic technical knowledge. It supported both audio and video communication over network connections, making it an early solution for remote collaboration. How NetMeeting Worked NetMeeting used a directory server model where users ...
Read MoreChat Conferencing Protocols
Chat conferencing protocols enable real-time communication between multiple users through various technologies and standards. These protocols define how messages are transmitted, how users connect to conversations, and what features are available during communication sessions. Understanding different chat conferencing protocols helps organizations and individuals choose the right solution for their communication needs, whether for casual messaging, team collaboration, or large-scale meetings. Chat Conferencing Protocol Categories Open Standards IRC, XMPP Team Platforms Slack, Teams Video Focus ...
Read MoreWhat is a Distributed Component Object Model (DCOM)?
Distributed Component Object Model (DCOM) is an extension of Microsoft's Component Object Model (COM) that enables software components to communicate across network boundaries. While COM handles local inter-process communication between components on the same machine, DCOM extends this capability to distributed environments where components reside on different computers. DCOM acts as a transparent middleware layer that replaces local inter-process communication with network protocols. Neither the client nor the component needs to be aware that they are communicating across a network — the connection simply becomes "a little longer" from their perspective. DCOM Architecture ...
Read MoreHow to View Colored Man Pages in Linux?
Man pages are important reference documents for Unix/Linux users, but their default appearance is plain text that can be hard to read. This article shows how to add colors and highlighting to man pages to make them more readable and easier to follow. Using most The most command is a pager that can display colored man pages. First, install it using your package manager ? sudo apt install most Once installed, add most as your default pager by adding this line to your .bashrc file ? export PAGER="most" Reload your ...
Read MoreHow to Run a Command with Time Limit (Timeout) In Linux
Sometimes a Unix command may run for a very long time without giving the final output or it may keep processing giving partial output from time to time. In such scenarios we need to put a time frame within which either the command must complete or the process should abort. This is achieved by using timeout tools. Using timeout Tool The timeout tool forces a command to abort if it cannot complete within a given time frame. This is a built-in utility available on most Linux systems. Syntax timeout DURATION COMMAND [ARG]... Where ...
Read MoreHow to create an Animated Art on Your Linux Terminal?
Linux terminals can display animated art using ASCII characters and specialized packages. These animations range from simple moving text to complex scenes like trains and castles, created using shell scripting and command-line utilities. Installing and Running the Steam Locomotive The sl package creates a fun train animation that "runs" across your terminal screen. Install it using the package manager and execute with a simple command ? sudo apt-get install sl sl Running the above code displays an animated steam locomotive moving across your terminal ? Creating ASCII Castle Animation You ...
Read MoreHow to Change or Set System Locales in Linux
We often need to customise the operating system to match our preferences like the language we want to use, the time zone we are in, or the type of currency which would become the default in the OS. In this article we will see how to customise these options which is known as locale. Checking Current Locale We can check the current locale by using the locale command as shown below. We get a list of variables which can be reset to different values as per our choice ? $ locale Running the above ...
Read MoreDifference between Relational Algebra and Relational Calculus
Relational Algebra and Relational Calculus are both formal query languages used to retrieve data from relational databases. Relational Algebra is procedural (specifies how to get the result), while Relational Calculus is declarative (specifies what result to get). Both are equivalent in expressive power. Relational Algebra Relational Algebra is a procedural query language that takes instances of relations as input and yields instances of relations as output. It uses operators to perform queries step by step. The fundamental operations are − Select (σ) − Filters rows based on a condition Project (π) − Selects specific columns Union ...
Read MoreDifference between monolithic and microservices architecture
Monolithic and Microservices are two different architectural approaches for building software applications. A monolithic architecture builds the entire application as a single, tightly coupled unit, while microservices architecture breaks it into small, independent services based on business functionality. Monolithic Architecture Monolithic architecture is built as one large system, usually as a single codebase. All components (UI, business logic, data access) are tightly coupled and deployed together. As the application grows, it becomes difficult to isolate services for independent scaling, and changing technology or frameworks becomes extremely challenging because everything depends on each other. Microservices Architecture Microservices ...
Read MoreDifference between Tester and SDET
In software quality assurance, Tester and SDET are two distinct roles with different skill sets and responsibilities. A Tester focuses on manual and functional testing, while an SDET combines development and testing skills to build automation frameworks and test software at a deeper level. Tester A software tester performs testing on the software to ensure it meets the required quality standards. A tester is responsible for checking if the software has bugs or defects and verifying that it performs as expected. A software tester is typically unaware of the application's internal code and development process, focusing on black-box ...
