Microarchitecture, also known as computer organization, refers to high-level hardware questions such as the design of the CPU, memory, and memory interconnect. [26] Memory hierarchy ensures that the memory quicker to access (and more expensive) is located closer to the CPU, while slower, cheaper memory for large-volume storage is located ...
Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software).
BASICs with Bitwise Ops use -1 as true and the AND and OR operators perform a bitwise operation on the arguments.. FOR/NEXT skip means that body of the loop is skipped if the initial value of the loop times the sign of the step exceeds the final value times the sign of the step (such as 2 TO 1 STEP 1 or 1 TO 2 STEP -1).
Comparatively, computer literacy measures the ability to use computers and to maintain a basic understanding of how they operate. [ 3 ] A person's computer literacy is commonly measured through questionnaires, which test their ability to write and modify text, trouble-shoot minor computer operating issues, and organize and analyze information ...
