Basic Operational Concepts | III | CS | Mod1 | CO | S1

[@priyanshukumarsinha6423]

The video is about basic operational concepts of a computer. The speaker first introduces the five functional units of a computer: input unit, output unit, memory, control unit, and arithmetic logic unit (ALU). The input unit allows users to provide information to the computer, such as through a keyboard or mouse. The output unit displays information to the user, such as on a monitor or printer. Memory stores data for later use. The control unit controls all the other units and ensures they work together properly. The ALU performs arithmetic and logical operations on data. The speaker then explains how instructions are executed by the computer. Instructions are stored in memory and loaded into the processor one at a time. The processor decodes the instruction and then executes it. To execute an instruction, the processor may need to fetch data from memory, perform an operation on the data in the ALU, and store the result back in memory. The speaker uses an example of adding two numbers to illustrate how instructions are executed. The program is first loaded into memory. Then, the processor fetches the first instruction, which is a load instruction. The load instruction tells the processor to load the value of a variable from memory into a register. The processor then fetches the second instruction, which is an add instruction. The add instruction tells the processor to add the values in two registers. The processor adds the values and stores the result in another register. Finally, the processor fetches the third instruction, which is a store instruction. The store instruction tells the processor to store the value in a register back into memory. The speaker also discusses how the computer's memory and processor communicate with each other using a bus. A bus is a set of wires that carries data between different parts of the computer. The computer uses three types of buses: address bus, data bus, and control bus. The address bus carries the address of the data that is being accessed. The data bus carries the data itself. The control bus carries control signals that tell the different parts of the computer what to do. The speaker concludes by mentioning that there are different types of bus structures, but the video only discussed the single bus structure. In a single bus structure, only two devices can be active at the same time. This can limit the performance of the computer. I hope this summary is helpful!

Load Loca ro Load locb r1 Add ro,r1 Why the result is stored in r0 again Anybody please explain me 9:25

[@thriveninallabati978]

@@sanjanahalli1174 see that result is finally stored in R1

[@thriveninallabati978]

@@sanjanahalli1174 here r0 is the main memory and R1 is a register so, that result is first load in the register R1 only.

Mam why doesn't Mit start the compiler design? we students are facing some difficulty in understanding so, we students request MIT to start the compiler design playlist.
