WebMar 6, 2024 · Social engineering is the term used for a broad range of malicious activities accomplished through human interactions. It uses psychological manipulation to trick users into making security mistakes or giving away sensitive information. Social engineering attacks happen in one or more steps. In computing, traditionally cycle stealing is a method of accessing computer memory (RAM) or bus without interfering with the CPU. It is similar to direct memory access (DMA) for allowing I/O controllers to read or write RAM without CPU intervention. Clever exploitation of specific CPU or bus timings … See more Some processors were designed to allow cycle stealing, or at least supported it easily. This was the case for the Motorola 6800 and MOS 6502 systems due to a design feature which meant the CPU only accessed memory … See more Unexpected cycle stealing by the rendezvous radar during descent nearly caused the Apollo 11 landing to be aborted, but the design of the Guidance Computer allowed the landing … See more Cycle stealing is difficult to achieve in modern systems due to many factors such as pipelining, where pre-fetch and concurrent elements are constantly accessing memory, leaving few predictable idle times to sneak in memory access.

WebIn word-at-a-time mode, the DMA controller requests the transfer of one word and gets it. If the CPU also wants the bus, it has to wait. The mechanism is called cycle stealing because the device controller sneaks in and steals an occasional bus cycle from the CPU once in a while, delaying it slightly. In block mode, the DMA controller tells the ...
