The CPU is the brain of a computer. What does CPU stand for? A. Computer Processing Unit B. Central Processing Unit C. Computer Power Unit D. Central Power Unit 相关知识点: 试题来源: 解析 B。解析:CPU 是中央处理器的缩写。反馈 收藏 ...
解析 A。本题考查“CPU”这个常见科技缩写的含义。选项 A“Central Processing Unit”意思是中央处理器,是“CPU”的正确全称。选项 B 中的“Computer Personal Unit”和选项 C 中的“Central Personal Unit”都不是“CPU”的正确全称。选项 D 中的“Computer Processing Unit”也是错误的表述。
An interrupt is a hardware-generated signal that changes the flow within the system. An interrupt can be used to signal the completion of I/O so that the CPU doesn't have to spend cycles polling the device. 中断是一种硬件生成的信号,可以改变系统内部的流量。一个中断可以用来发出I/O的完成信...
1's and 0's: What a CPU Does Thanks to more powerful CPUs, we've jumped from barely being able to display an image on a computer screen to Netflix, video chat, streaming, and increasingly lifelike video games. The CPU is a wonder of engineering, but, at its core, it still relie...
how does a cpu work? a cpu works by executing instructions that have been read from memory - these instructions tell the cpu what operations need to be performed on particular data items stored in memory or registers. when an instruction is fetched from memory it is sent through the control...
A. Central Processing Unit B. Computer Programming Unit C. Central Programming Unit D. Computer Processing Unit 相关知识点: 试题来源: 解析 A。“CPU”是“Central Processing Unit”的缩写,意思是中央处理器。选项 B、C、D 都是错误的表述。所以选 A。 反馈 收藏 ...
解析 A。本题考查常见科技缩略词的含义。“CPU”是“Central Processing Unit”的缩写,意为中央处理器。选项 B“Communication Processing Unit”是通信处理单元;选项 C“Computer Processing Unit”是计算机处理单元;选项 D“Central Programming Unit”是中央编程单元。只有选项 A 符合“CPU”的正确含义。
A processor (CPU) is the logic circuitry that responds to and processes the basicinstructionsthat drive a computer. The CPU is seen as the main and most crucial integrated circuitry (IC)chipin a computer, as it is responsible for interpreting most of computers commands. CPUs will perform most...
(ips). the higher the ips, the faster the speed at which tasks can be completed. the number of instructions that a cpu can handle depends on its clock speed (the frequency at which it executes instructions) and other factors such as architecture and cache size. why does cpu performance ...
An instant increase in the CPU usage may indicate that an operation has just been performed, for example, the device has just been started, information about all optical modules has been queried, or the volume of traffic has increased instantly. This situation does not affect the device ...
