Introduction Memory management is a complex technique that is solved using various memory management algorithms and techniques employed by operating systems to optimize memory usage. The different memory management techniques vary depending on the operating system and hardware architecture. Effective memory management is very crucial for the overall performance, stability, Read more…
Terminology CPU Utilization: CPU Utilization is making the CPU is busy all the time, so that all the associated components of the system also utilized high. The maximum CPU utilization makes the system performance high. In another words, CPU utilization is the ratio of busy time of the processor to Read more…
