Linux kernelFree Unix-like operating system kernelThe Linux kernel is a free and open-sourceUnix-likekernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNUoperating system (OS), which was created to be a free replacement for Unix. Since the late 1990s, it has been included in many operating system distributions, many of which are called Linux.
FreeBSDFree and open-source Unix-like operating systemOperating systemFreeBSD is a free and open-sourceUnix-likeoperating system descended from the Berkeley Software Distribution (BSD). The first version was released in 1993 developed from 386BSD, one of the first fully functional and free Unix clones on affordable home-class hardware, and has since continuously been the most commonly used BSD-derived operating system.
NetBSDFree and open-source Unix-like operating systemOperating systemNetBSD is a free and open-sourceUnix-likeoperating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems.
List of Bluetooth profilesThe Bluetooth logoIn order to use Bluetooth, a device must be compatible with the subset of Bluetooth profiles (often called services or functions) necessary to use the desired services. A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices. It resides on top of the Bluetooth Core Specification and (optionally) additional protocols.
Embedded systemAn embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/outputperipheral devices—that has a dedicated function within a larger mechanical or electronic system. It is embedded as part of a complete device, often including electrical or electronic hardware and mechanical parts. Embedded systems control many devices in common use.
Protocol stackThe protocol stack or network stack is an implementation of a computer networkingprotocol suite or protocol family. Some of these terms are used interchangeably, but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them. Individual protocols within a suite are often designed with a single purpose in mind. This modularization simplifies design and evaluation.Netgraphnetgraph is the graph based kernel networking subsystem of FreeBSD since 3.4 and DragonFly BSD since the fork from FreeBSD. Netgraph provides support for L2TP, PPTP, ATM, Bluetooth using a modular set of nodes that are the graph.List of Bluetooth protocolsThe wireless data exchange standard Bluetooth uses a variety of protocols. Core protocols are defined by the trade organization Bluetooth SIG. Additional protocols have been adopted from other standards bodies. This article gives an overview of the core protocols and those adopted protocols that are widely used.
BluetoothShort-range wireless technology standardA Bluetooth earbud, an earphone and microphone that communicates with a cellphone using the Bluetooth protocolBluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).
Open sourceOpen source is the practice of publishing digital resources publicly alongside their source code or source files, enabling use, study, modification, and redistribution. It is historically and commonly associated with open-source software, software released with its source code.ImplementationImplementation is the realization of an application, execution of a plan, idea, model, design, specification, standard, algorithm, policy, or the administration or management of a process or objective.
SoftwareSoftware (SW) consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware.*As an Amazon Associate I earn from qualifying purchases.
