Think of it like this: In a single-player game, your computer does everything. In a multiplayer game, the game server acts as the referee, making sure everyone plays by the rules and sees the same game, preventing conflicts and ensuring a fair and enjoyable experience for everyone involved. The players' computers only handle the visual display and input; the game's core functionality happens on the server.

VoIP stands for Voice over Internet Protocol. It's a technology that allows you to make voice calls over the internet instead of a traditional telephone line. Instead of using the public switched telephone network (PSTN), VoIP uses the internet's data network to transmit voice data as digital packets. Think of it like this: instead of sending sound waves through copper wires, VoIP converts your voice into digital data, sends it as packets over the internet, and then reconstructs it as sound at the other end. Here's what makes VoIP different: Lower cost: Often significantly cheaper than traditional phone calls, especially for long-distance or international calls. Flexibility: Can be used on various devices (computers, smartphones, tablets) and often integrates with other communication tools (like messaging and video conferencing). Features: Many VoIP services offer advanced features like voicemail-to-email, call forwarding, call waiting, and conference calling. Scalability: Easy to add or remove phone lines as needed.
