Threads have their own thread ID, program counter (PC), a register set, and a stack, but share code, heap data, and other resources with other threads of the same process. [87] [88] Thus, there is less overhead to create a thread than a new process. [89] On single-CPU systems, concurrency is switching between processes.
Legacy systems are considered to be potentially problematic by some software engineers for several reasons. [4]If legacy software runs on only antiquated hardware, the cost of maintaining the system may eventually outweigh the cost of replacing both the software and hardware unless some form of emulation or backward compatibility allows the software to run on new hardware.
Some suggested that Microsoft had acknowledged "implicitly ringing the desktop PC death knell" as Windows 8 offered little upgrade in desktop PC functionality over Windows 7; instead, Windows 8's innovations were mostly on the mobile side. [21] The post-PC trend saw a decline in the sales of desktop and laptop PCs.
