It uses a low-power, short-range radio transmitter in each device within a small area called a piconet. A piconet can have one master device and up to seven connected slave devices. Bluetooth devices communicate by frequently changing radio frequencies using a technique called frequency-hopping spread spectrum. Common applications of Bluetooth technology include file transfer, internet access, synchronization, and connecting headsets.
Bluetooth is a wireless technology that allows short-range connections between electronic devices like computers, phones, and other portable devices. It uses radio waves instead of wires to connect devices within about 30 feet of each other, eliminating the need for direct line-of-sight connections. A group of companies formed the Bluetooth Special Interest Group to develop the Bluetooth specifications and promote its use. While initially developed for business users, Bluetooth's ability to connect diverse devices wirelessly has led to its use in many consumer products as well.
This document summarizes a seminar on Bluetooth technology. Bluetooth allows for short-range wireless communication between various smart devices.

It defines key elements of autonomic computing like self-configuration, self-optimization, self-healing, and self-protection. The document also outlines the autonomic computing architecture, which involves autonomic managers that monitor and control managed elements using sensors and effectors. It acknowledges autonomic computing as a grand challenge and concludes that while fully solving AI is not required, incremental progress can still provide valuable autonomous systems over time to address this challenge.
This document discusses asynchronous computer chips as an alternative to traditional synchronous chips. Synchronous chips rely on a central clock, which poses problems like slow speed, wasted energy distributing the clock globally, and high power consumption from the clocks themselves. Asynchronous chips do not use a central clock and instead rely on handshake signals between components to transfer data only when needed. They allow different parts to work at different speeds and immediately pass results. While asynchronous chips have advantages like lower power usage and less noise, challenges remain in interfacing them with synchronous devices and a lack of expertise and tools available. Overall, the document argues that asynchronous chips may help address future issues with clocked designs as chip complexity increases.
