- Shift register (Wikipedia)
A shift register is a type of digital circuit using a cascade of flip-flops where the output of one flip-flop is connected to the input of the next. They share a single clock signal, which causes the data stored in the system to shift from one location to the next. By connecting the last flip-flop back to the first, the data can cycle within the shifters for extended periods, and in this configuration they were used as computer memory, displacing delay-line memory systems in the late 1960s and early 1970s.
- Freedom Caucus (Wikipedia)
The Freedom Caucus, also known as the House Freedom Caucus, is a congressional caucus consisting of Republican members of the United States House of Representatives. It is generally considered to be the most conservative and furthest-right bloc within the chamber. The caucus was formed in January 2015 by a group of conservatives and Tea Party movement members, with the aim of pushing the Republican leadership to the right. Its first chairman, Jim Jordan, described the caucus as a “smaller, more cohesive, more agile and more active” group of conservative representatives. Members of the Freedom Caucus are typically considered a part of the MAGA movement and loyalists to Donald Trump.
