An efficient request-reply protocol for a client-server communication and data processing model. Under the novel protocol, a client sends a Request to a server and awaits a Reply. If the Reply is not sent before expiration of a timeout period in the client, the client sends a second Request. The server provides a conditional Acknowledge if a second Request is received from the client. Thereafter, the client waits for the server to transmit a Reply without the client sending additional Requests. Under normal conditions, the inventive protocol performs as well as the best prior art protocol (the optimistic model), while under abnormal conditions, the inventive protocol performs better than the optimistic protocol and only slightly worse than the prior art pessimistic protocol. Since normal conditions should prevail for a substantially longer amount of time than abnormal conditions, the present invention provides better average performance than either prior art client-server protocol.

Yes, a computer operating system can be downloaded onto your computer. One of the most common file formats to download operating systems is the .img file format. The .img file format can be used by programs like Oracle's VirtualBox, to create a virtual computer on your own computer. This uses the operating system that is saved in the .img file without overriding your current computers operating system and basically creates another "fake" or virtual computer within your own computer. However, these operating systems can also be used to replace your current operating system or to dual boot your computer, this means to have two operating systems installed on one computer at the same time. Operating systems can also be downloaded for the sole purpose of replacing your current operating system. For example, when a person upgrades their computer from running Windows 8.1 to Windows 10, they are essentially downloading a new operating system on to their computer from Microsoft, but in a way that it completely replaces their current operating system.
An operating system runs common services for computer programs and manages the computer hardware resources. An operating system is necessary to run application programs.
