Difference between System Unit and CPU
System Unit: The system Unit is the hardware element of the PC system. It varies in size and possesses completely different sizes per specific PC kind and its demand for work. It is additionally known as the system chase, computer case, computer chassis, etc. The System unit contains an optical drive, hardware, RAM, power supply, BIOS, motherboard, processors, fans, peripheral devices, etc. It’s not a purposeful unit itself, however, it provides the surroundings to all or any of the opposite purposeful units and interiors to collaborate and work conjointly in a very ordinarily hooked-up hardware chase. It’s sometimes created from aluminum or typically metal. It varies in form and size per the necessities of the PC or Computer.
Central Processing Unit (CPU): The CPU is known as the brain for every ingrained system. CPU comprises the arithmetic logic unit (ALU) accustomed quickly to storing the information and performing calculations and Control Unit (CU) for performing instruction sequencing as well as branching. CPU interacts with more computer components such as memory, input, and output for performing instruction.
Let’s see the difference between System unit and CPU :
|S. No.||System Unit||CPU|
|1.||The system Unit does not have any full form.||CPU stands for Central Processing Unit.|
|2.||It manages the entire computer.||Whereas it is part of the system unit.|
|3.||Without a CPU system unit is nothing.||It is the heart or brain of the system unit.|
|4.||It is not responsible for giving the answer or solution to queries.||While it is responsible for giving the answer or solution to queries.|
|5.||The system unit is the computer system’s part or unit.||Whereas it is the small unit of the system unit.|
|6.||The System unit contains or provides the power supply to the entire computer system.||While it does not have a power supply.|
|7.||The System unit contains an optical drive, hardware, RAM, power supply, BIOS, motherboard, processors, fans, peripheral devices, etc.||Whereas it contains microprocessor, that process data.|
|8.||The task of a system unit is to hold everything inside the computer that occupies the space in it. It enables the electrical units, including the processors, to operate cooperatively in a shared hardware environment. ||The task of the CPU is to perform processing of data entered which is input into the computer and then output the information after processing it. The sending of instructions by the user to the processors enable the computer to perform every function.|
|9.||The number of system units for a single device never changes regardless of the number of CPUs present in a computer system. It always remains one.||A computer system may have one or more CPUs.|
