What is the purpose of page replacement algorithm?
What is the purpose of page replacement algorithm? Page replacement algorithms are an important part of virtual memory management and it helps the OS to decide which memory page can be moved out, making space for the currently needed page. However, the ultimate objective of all page replacement algorithms is to reduce the number of […]

Who made the steam locomotive? George Stephenson What machines were used during the Industrial Revolution? Machinery during the Industrial Revolution such as the […]
What is evolution of computer system?
What is evolution of computer system? Computing began at the mechanical level, added an information level (software), then a human level and finally a community level; it is an example of general system evolution. As computing evolves to higher system levels, so its design also changes, from technical to socio-technical design. What is the difference […]
