Number, Arithmetic Operations, and Characters. The instructions constituting a program to be executed by a computer are loaded in sequential locations in its main memory. The order and organization of learning activities affects the way information is processed and retained (Glynn & DiVesta, 1977; Lorch & Lorch, 1985; Van Patten, Chao, & Reigeluth, 1986) A number of theories (e.g., Bruner, Reigeluth, Scandura) suggest a simple-to-complex sequence. It was included as part of the Von Neumann Architecture by John von Neumann. II Computer Instruction and format, Instruction Cycle 20. Reduced Instruction set computer. This process is repeated continuously by CPU from boot up to shut down of computer. Instructions are fetched from successive memory locations until the execution of a branch or a jump instruction. Computers may have instructions of several different lengths containing varying number of addresses. Instruction codes together with data are stored in memory. Fetch the Instruction INSTRUCTIONS AND INSTRUCTION SEQUENCING Four types of operations Data transfer between memory and processor registers. The number of address fields in the instruction format of a computer depends on the internal organization of its registers. Computer Organization Unit 2.
