...mance and power profiles, i.e. some cores run fast but draw lots of power (faster architecture and/or higher clocks) while others are energy-efficient but slow (slower architecture and/or lower clocks). This is useful because power usage tends to increase disproportionately as you increase performan...
...阅读器RJSmith92想知道如果**USB 3.0端口,USB 2.0设备是否能更快充电: Do USB 2.0 devices charge faster if they are plugged into a USB 3.0 port rather than a USB 2.0 one? I am not asking about a specific device, I just mean in general. I know that a USB 2.0 port can provide 500mA a...
...t-hours of energy. Most Li-Ion batteries are not designed to be discharged faster than twice their watt-hours rating per hour (2C) and continuous discharge at rates exceeding 1C can significantly reduce the life of the battery. Continuously pulling 150 watts or more from a typical 77 watt-hours batt...

...M helps programs you’re actively using — say, your web browser — run faster, because if they need to claim a new segment of RAM (like when you open a new tab), they can do so. This “free” RAM is also used as page cache, which means that when active programs attempt to read data on your ha...
SATA硬盘驱动器连接比旧的PATA硬盘驱动器连接更快,对于外部布线标准也可以这样说,但这是违反直觉的:为什么并行传输不会更快? 今天的问答环节是由SuperUser提供的,SuperUser是Stack Exchange的一个分支,是一个由社区驱动的问...

...汉斯·帕桑斯(Hans Passants)插话解释了为什么电脑会感觉更快: The only way your machine could have gotten faster is by the paging file getting relocated to a less fragmented part of the disk when you changed its size. A common problem in general on old XP machines. Get a furth...
...ssue it was 30 years ago. Back then you had hard drives that were scarcely faster than floppies, and processor memory sizes that were minuscule. Now you have very fast drives and large processor memories, and sometimes substantial buffering on the hard drive or in the controller. Plus sector sizes h...
