Context and question: USB device communication is based on pipes (logical channels). A pipe is a connection from the host controller to a logical entity, found on a device, and named an endpoint. Because pipes correspond 1-to-1 to endpoints, the terms are sometimes used interchangeably. A USB device could have up to 32 endpoints (16 IN, 16 OUT), though it's rare to have so many. An endpoint is defined and numbered by the device during initialization (the period after physical connection called "enumeration") and so is relatively permanent, whereas a pipe may be opened and closed.
A USB connection is based on what?
Answer: pipes (logical channels)
Context and question: The French were equipped with bronze, rifled muzzle-loading artillery, while the Prussians used new steel breech-loading guns, which had a far longer range and a faster rate of fire. Prussian gunners strove for a high rate of fire, which was discouraged in the French army in the belief that it wasted ammunition. In addition, the Prussian artillery batteries had 30% more guns than their French counterparts. The Prussian guns typically opened fire at a range of 23 kilometres (1.21.9 mi), beyond the range of French artillery or the Chassepot rifle. The Prussian batteries could thus destroy French artillery with impunity, before being moved forward to directly support infantry attacks.
What did the French believe was overly wasted in artillery with a higher rate of fire?
Answer: ammunition
Context and question: Conversely, most heat-treatable alloys are precipitation hardening alloys, which produce the opposite effects that steel does. When heated to form a solution and then cooled quickly, these alloys become much softer than normal, during the diffusionless transformation, and then harden as they age. The solutes in these alloys will precipitate over time, forming intermetallic phases, which are difficult to discern from the base metal. Unlike steel, in which the solid solution separates to form different crystal phases, precipitation hardening alloys separate to form different phases within the same crystal. These intermetallic alloys appear homogeneous in crystal structure, but tend to behave heterogeneous, becoming hard and somewhat brittle.
Precipitation hardening alloys are sometimes also?
Answer:
heat-treatable alloys
