1. COMPUTER SYSTEM ORGANISATION Presentation Made By: Ms. Archika Bhatia

3. BLOCK DIAGRAM OF COMPUTER INPUT UNIT OUTPUT UNIT MEMORY CENTRAL PROCESSING UNIT ALU CU Registers

4. INTERNAL VIEW OF THE COMPUTER • The part of the PC that you actually see is the case • It is officially called the "system unit,“ but generally called as the case.

5. • Everything is connected to the motherboard • A motherboard is a thin, flat piece of circuit board, usually of green or gold color, usually slightly larger than a piece of paper. Motherboard

11. RAM ROM

15. HARD DRIVE COMPACT DRIVE

16. Concentric circles on the magnetized surface of the magnetic disks are known as Tracks The tracks on the disk surface are divided into invisible segments known as Sectors Tracks Sectors

24. CISC AND RISC Architecture: the architecture of the processor 5. Requires less transistors of hardware space. 5. Requires more transistors of hardware space 4. Register to Register: “ LOAD and STORE” are independent instructions 4. Memory to Memory: “LOAD” and “STORE” incorporated in instructions 3. Large code sizes but each instruction requires only one clock cycle. 3. Small code size but more clock cycles required for single instruction. 2. Single-clock reduced instruction only. e.g. LOAD A, 2:3 LOAD B, 5:2 PROD A, B STORE 2:3, A 2. Includes multi-clock complex instructions. e.g. MULT 2:3, 5:2 1. Reduced Instruction Set Computer 1.
