RAM, ROM, CPUROMCPURAMCPU means a centralprocessing unitThe CPU is the part of a computer system that iscommonly known as the 'Brains of the computer'.RAM is a type of data storage.Random access memoryA random-access memory device allows data items to be accessed(read or written) in almost the same amount of time irrespective ofthe physical location of data inside the memory.Once data has been written onto a ROM chip, it cannot be removed and can only be read.Unlike main memory (RAM), ROM retains its contents even when the computer is turned off.ROM is referred to as being nonvolatile, whereas RAM is volatile.Read only memoryA typical CPU has a number of components. The first is the arithmetic logic unit (ALU), which performs simplearithmetic and logical operations. Second is the control unit (CU), which manages the various components of thecomputer.In a computer, clock speed refers to the number of pulses per second generated by anoscillator that sets the tempo for the processor. Clock speed is usually measured in MHz(megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses persecond).Ram is a type of computer memory that can be accessed randomlyMotherboarda printed circuit board containing the principalcomponents of a computer or other device, withconnectors for other circuit boards to be slottedinto.Double click this nodeto edit the textClick and drag this buttonto create a new node
