Slide 1 Computer Systems Registers & Register handling Slide 2 Registers Small memory inside CPU- Hold code & data fetched from RAM for processing. Very fast computer memory inside CPU Purpose is fast retrieval of data Get data from RAM which are above to get executed. Bigger the size the registers- fewer clock cycles to execute the data because more data can be processed at the same time. Ex: 8-bit register can hold 1 byte of data & 128 bit can hold 16 byte of data. Types : Accumulator General

Slide 1 MAT-470-18306-M01 Real Analysis 2024 C The Riemann Integral Jared Carroll 13/12/20241 Slide 2 Introduction to Riemann Integral What is Integration? Integration is the process of finding the area under a curve on a graph. It measures accumulation, such as distance, area, or volume. Historical Context Isaac Newton and Gottfried Wilhelm Leibniz developed integration in the late 17th century as the inverse of differentiation. Bernhard Riemann (1850s) redefined integration rigorously by focusing on approximating areas through sums (Riemann sums). Why the Riemann Integral? Provides a robust…
