This course details about Computer Organization.
Before understanding the computer organization, let’s discuss about the CPU.
Central Processing Unit (CPU):
The CPU is the core part of a computer because it performs major functionalities, such as storing and processing data. It consists of the control unit, the arithmetic, the logical unit, and the memory unit. While the control unit transfers the instructions and data, the memory unit helps store the data and instructions.
The ALU unit contains two sections: Arithmetic and logic. The arithmetic section involves performing arithmetic operations such as addition, multiplication, subtraction, and division. The logic section performs logical functions such as matching, comparing, analyzing, and selecting.
The CPU also consists of Floppy disks, a hard drive, an optical disc drive, three or four RAM modules or slots, and a microprocessor. As a result, the CPU holds the CPU controls the control of the entire computer operations.
Notably, some of the most critical components, namely the microprocessor and RAM, are located on the motherboard within the CPU.
Within the CPU, we can also see the power supply unit and a system fan inside the CPU.
Where will the Computer Store the information?
Whatever information/code the programmer types or provides will be stored in the main memory.
What happens to the Data inside the Main Memory?
Once the data arrives at the main memory, there will be a status change, and the operating system will come and read those newly arrived bytes. Then, the operating system will delegate those instructions to the destinations based on the bytes and identified information. All the data need not go to the CPU but the data that needs to be processed alone. The CPU will apply the arithmetical logical unit (ALU), perform that operation, and send the processed data as information to the main memory. Finally, the main memory delegates the data to the respective output devices from the main memory. The above steps enable an understanding of how the entire program will be executed, a main insight of computer organization.
