Final answer:
P2P systems provide real-time access to other users, allow computers to act as both clients and servers, and support protocols like SOAP or XML-RPC, but they are not characterized by a lack of tools for content creation or adding functionalities. This is an incorrect characterization of P2P systems, which tend to be adaptable and allow for the easy creation and sharing of content.
Step-by-step explanation:
P2P (Peer-to-Peer) systems generally have several key characteristics. They allow for real-time access to other users, with instant messaging and multichannel collaboration applications being common features. Users' computers in a P2P network have the capability to act as both clients and servers, dynamically sharing the role of providing and consuming resources. P2P systems also typically support cross-networking protocols such as SOAP or XML-RPC, which facilitate the execution of programs across different computers over the network.
However, the characteristic that P2P systems do not have is 'The overall system is well integrated, but lacks tools for easy creation of content or for adding functionalities.' P2P networks are designed to be adaptable and scalable, with users often having the tools to easily create and share content, and to extend the system's functionalities through various applications and services.
While P2P systems enable effective collaboration and sharing, their decentralized nature usually means they are not inherently well-integrated systems compared to centralized services. Centralized services like cloud storage providers and collaboration platforms offer well-integrated environments that, unlike typical P2P systems, include managed version control, comments, and review features to aid in the creation and modification process, ensuring that users are always working with the latest version of a document or file.
