Bluetooth is the wireless technology commonly identified in IT fundamentals as supporting short-range communication up to around 300 feet in higher-power implementations. Bluetooth is designed for personal area networking, connecting devices such as headphones, keyboards, speakers, and smartphones with low power consumption and easy pairing. Different Bluetooth classes exist: some provide only a few meters of range, while higher-power versions can extend to roughly 100 meters, which is close to 300 feet, under good conditions. Wi-Fi typically supports larger local-area coverage and is used to connect devices to local networks and the internet. A wide area network is not a wireless technology standard; it is a type of network spanning large geographic areas. Near field communication is designed for extremely short distances, usually a few centimeters, and is used for contactless payments and quick device taps. Since the question asks for a wireless technology specifically accommodating distances up to 300 feet, Bluetooth best matches that description.

Google Apps, Dropbox, and GoToMeeting are all examples of Software-as-a-Service (SaaS). SaaS is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the internet. This contrasts with IaaS, which provides virtualized computing resources over the internet, and PaaS, which offers hardware and software tools over the internet.

1.Google Apps (now Google Workspace) provides productivity and collaboration tools.

2.Dropbox offers cloud storage and file synchronization services.

3.GoToMeeting is an online meeting, desktop sharing, and video conferencing software.

All three services are accessed over the internet and do not require users to manage hardware or software updates, which is characteristic of the SaaS model.

Shareware is software distributed at no cost initially but typically provided as a limited version with restrictions. The limitations may include reduced features, a trial period, watermarks, usage limits, or reminders to purchase the full product. In Information Technology, shareware is often used as a marketing and distribution model that allows users to evaluate software before buying a license to unlock full functionality. This differs from freeware, which is available at no cost and is usually fully functional, though the author retains copyright. Public domain software has no copyright restrictions and can be used, modified, and redistributed freely, which is different from a limited trial distribution model. Closed-source refers to software where the source code is not publicly available, but it does not automatically mean the software is free or functionally limited. Since the question describes a functionally limited version available at no cost, the correct type of software is shareware.
