Splet24. dec. 2024 · This switch is what is called context switch. Now, threads executing on different cores are executed in parallel. Most modern CPUs have a number of cores, however, most modern OSes (windows, linux and friends) usually execute much larger number of threads, which still causes context switches. SpletAbstract Asynchronous transfer mode (ATM) is a cell-oriented switching and multiplexing technology that uses fixed-length (53 byte; 48 bytes of data, and 5 bytes of header information) packets—called cells—to carry various types of traffic, such as data, voice, video, multimedia, and so on, through multiple classes of services. ATM is a 1
