Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves.
Matthew 7:15 KJV
How much then is a man better than a sheep? Wherefore it is lawful to do well on the sabbath days.
Matthew 12:12 KJV
- How flip-flops are implemented in the Intel 8086 processor (righto.com)
A key concept for a processor is the management of “state”, information that persists over time. Much of a computer is built from logic gates, such as NAND or NOR gates, but logic gates have no notion of time. Processors also need a way to hold values, along with a mechanism to move from step to step in a controlled fashion. This is the role of “sequential logic”, where the output depends on what happened before. Sequential logic usually operates off a clock signal,1 a sequence of regular pulses that controls the timing of the computer. (If you have a 3.2 GHz processor, for instance, that number is the clock frequency.)
To create man was a fine and original idea; but to add the sheep was a tautology.
Mark Twain
- Sheep (Wikipedia)
Sheep or domestic sheep (Ovis aries) are domesticated, ruminant mammals typically kept as livestock. Although the term sheep can apply to other species in the genus Ovis, in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe (/juË/), an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb.
