Input unit of a computer: Their Role
Now looking into the hardware computer components, the classification consists of input devices, CPU, and output devices.
The input unit consists of devices such as the keyboard and mouse, which enable users to enter data into the computer. The input unit creates a connection between the programmer and the computer.
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, namely the arithmetic and logic section. 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.
Components of a computer, together, make the efficient working of the larger, more sophisticated electronic device. The overall computer efficiency depends on each component’s unique functioning. Although the central processing unit (CPU) is the main component and it is known as the computer’s brain, equally important to the CPU are the input and output devices […]
