Question

Following is a freeware :

• A. DLT System
• B. LAMP
• C. NCIP
• D. IRC

Hint:

Distinguish between concepts, protocols, and software. IRC is a protocol, but it's strongly associated with the freeware client software used to access it, making it the best fit.

Answer 1

The Correct Option is D

Step 1: Define Freeware. Freeware is software that is available for use at no monetary cost but is copyrighted by its developer, who retains the rights to control its distribution, modify it, and sell it in the future. It is different from free and open-source software.

Step 2: Analyze the options. \[\begin{array}{rl} \bullet & \text{DLT System (Distributed Ledger Technology): This is a technological concept (like blockchain), not a single piece of software.} \\ \bullet & \text{LAMP (Linux, Apache, MySQL, PHP/Perl/Python): This is a software stack whose components are overwhelmingly Free and Open-Source Software (FOSS), not just freeware.} \\ \bullet & \text{NCIP (NISO Circulation Interchange Protocol): This is a protocol or standard, not software.} \\ \bullet & \text{IRC (Internet Relay Chat): This is a protocol, but it is most commonly accessed through client software. Many of these clients (like the original mIRC for Windows) were distributed as freeware or shareware, making IRC the concept most closely associated with freeware among the choices.} \\ \end{array}\]
