State examples of distributed operating systems?

# The Systems Engineering group at NI has developed a set of data logging and monitoring example LabVIEW code for test cells and similar uses. The example application is configuration-driven (point/click, drag/drop), and suitable for use with DAQmx, Fieldpoint, and custom (VI-based) I/O servers. It illustrates a method for building LabVIEW DSC-based client/server systems as well as various styles of client displays. 2. OLTP (Online Transaction Processing) Online reservation systems in traveling agencies are an example of OLDP. In these kind of systems there is a central system and there are many other machines that are connected to the central system from different geographical locations. # An example of distributed computing is, a framework in which large problems can be divided into many small problems which are distributed to many computers. Later, the small results are reassembled into a larger solution. # Other examples of Distributed system are projects, that include the Department project, which is focused on simulations of to find disease cures and to understand biophysical systems;, an effort to create the world's largest public computing grid to tackle scientific research projects that benefit humanity, run and funded by;, which is focused on analyzing radio-telescope data to find evidence of intelligent signals from space, hosted by the at the; and, which is focused on breaking various cryptographic ciphers. 5. Groupware applications like Lotus Note In the above systems there are usually clients and servers and there is network in between. On the server side there may be databases and database management systems and on the client side there may be any number of clients with different applications. Client applications may be thick or thin. Thin client programs have very little business logic in them like an applet or an HTML browser but thick client programs have a lot of business logic and computations in them like banking or simulation applications. 1. The Internet - Heterogeneous network of computers and applications - Implemented through the Internet Protocol Stack 2. Distributed Multimedia-Systems - Often use Internet infrastructure - Characteristics iHeterogeneous data sources and sinks that need to be synchronized in real time * Video * Audio * Text iOften: Distribution services * Multicast - Examples iTeleteaching tools (mbone-based, etc.) iVideo-conferencing iVideo and audio on demand Intranets - Locally administered network - Usually proprietary (e.g., the University campus network) - Interfaces with the Internet iFirewalls - Provides services internally and externally Mobile and Ubiquitous Computing Systems - Cellular phone systems (e.g., GSM, UMTS) iResources being shared * Radio frequencies * Transmission times on one frequency (UMTS: multiplexing) * The mobile on the move - Laptop computers iWireless LANs (faculty campus WLAN, "MoPo") - Handheld devices, PDAs etc. - Wearable devices Embedded systems - The networked coffee mug - Avionics control systems iFlight management systems in aircraft - Automotive control systems iMercedes S-Klasse automobiles these days are equipped with 50+ autonomous embedded processors iConnected through proprietary bus-like LANs - Consumer Electronics iAudio HiFi equipment
