PPT-Lecture 13: Computer Memory

CSE 373 Data Structures and Algorithms CSE 373 SP 18 Kasey Champion 1 Administrivia Sorry no office hours this afternoon Midterm review session Monday 68pm Sieg 134 hopefully Written HW posted later today individual assignment. Memory Memory is a property relev ant o nly to systems whose input and output signals have the same independent variable A system is said to be memoryless if its output for each value of the independent variable is dependent only on the input signa Computer Concepts.

Primary storage is also called memory.. Secondary storage is often called storage.. A computer is a machine that is used to store and process data electronically. Computer Definition. Hardware.

Introducing Your Instructor. I’m not a professor – call me Justin. Data are represented in the computer memory in bits. That is 0s and 1s. . 8bits make up a byte.. Data entered into the computer have to be converted into the machine readable form.. In a better . way of handling complex types of data ( long streams of binary digits). Higher number systems are used in computing to reduce the streams of binary into manageable form, thus helps to improve the processing speed and optimize . Prof. Onur Mutlu. ETH Zürich.
