[Q]: In contrast to the internal, or L1 type, the L2 type sits between the CPU and DRAM, but both L1 and L2 are made of high-speed SRAM for the memory type. This disk type actually uses main memory, but stores information in a memory buffer. The original Pentium processor had a 16 kilobyte one of these built into it. FTP, name this high-speed storage mechanism that keeps frequently accessed data in a location separate from the main memory for rapid recall.
[A]: Science

[Q]: Loewner's inequality relates the area and systole of Riemannian metrics on one of these spaces. Arnold's cat map is a chaotic mapping from one of these spaces to itself. This name is given to connected, compact, abelian Lie subgroups, and any compact Lie group has a maximal one. Dupin cyclides are geometric inversions of these objects, and two Villarceau circles can be created by cutting one of these objects diagonally. N-dimensional versions of these objects, which have genus one, are homeomorphic to the Cartesian product of N circles. Other than the Klein bottle, these are the only closed, compact surfaces with an Euler characteristic of zero. They can be created by revolving a circle around an axis coplanar to the circle's diameter. For 10 points, name these mathematical objects that often look like doughnuts.
[A]: Science

[Q]: The Satsuma Rebellion occurred during this period. Most political power during this period was held by Choshu and Tosa clan leaders, in spite of an authoritarian constitution drafted by Ito Hirobumi. Founded under the slogan "Enrich the country and strengthen the military," this period's philosophy was espoused in the Charter Oath and propagated the return of imperial rule. Occurring after the overthrow of the Tokugawa shogunate in 1868, FTP, identify this period of modernization in Japanese history known as the "restoration" of its namesake emperor.
