1 operating system
"The software that controls the allocation and usage of hardware resources such as memory, central processing unit (CPU) time, disk space, and peripheral devices. The operating system is the foundation on which programs are built." -
2 64 bit machine
"A computer that works with data in groups of 64 bits at a time. A computer may be considered a 64-bit machine either because its CPU operates internally on 64-bit words or because its data bus can transfer 64 bits at a time. A 64-bit CPU thus has a word size of 64 bits, or 8 bytes; a 64-bit data bus has 64 data lines, so it ferries information through the system in sets of 64 bits at a time. Examples of 64-bit architecture include the Alpha AXP from Digital Equipment Corporation, the Ultra workstation from Sun Microsystems, Inc., and the PowerPC 620 from Motorola and IBM." -
3 Resource Monitor
"A component of Windows Reliability and Performance Monitor that displays real-time CPU, memory, disk, and network performance information collected from the Windows Kernel Trace provider and performance counters." -
4 profiling
"The collection of detailed performance data, such as memory, stack frame, and CPU utilization, during application execution. Analysis of the resulting data often leads to code optimizations that substantially improve application run-time behavior."
