in GHz dictates how quickly it can process instructions Memory Storing Data and Instructions Memory acts as the computers shortterm storage It holds the programs and data currently in use Think of it as a temporary workspace where information is readily accessible for the CPU There are two primary types RAM Random Access Memory Volatile memory meaning it loses its contents when the computer is turned off Its crucial for the CPUs quick access to programs and data ROM ReadOnly Memory Nonvolatile memory containing essential startup instructions BIOS It remains intact even when the computer is powered off Storage Devices Persisting Data Beyond RAM computers use storage devices like hard drives or solidstate drives SSDs for longterm data storage These devices retain information even after the power is off Hard Disk Drives HDDs Traditional storage method using magnetic platters SolidState Drives SSDs Newer technology using flash memory for faster and more durable 2 storage Optical Drives Used less frequently nowadays employing lasers to read and write data on CDs DVDs and Bluray discs Input Devices Guiding the Computer These devices allow users to interact with the computer and provide it with instructions Keyboard Used to type text Mouse Used to navigate and select items on the screen Touchscreen Combined input and display technology Microphone For voice input Webcam Captures visual input Output Devices Communicating Results These devices convey the results of the computers processing to the user Monitor Displays graphical information Printer Produces hard copies Speakers Play audio output Motherboard The Central Hub The motherboard is a crucial circuit board that connects all the internal components It provides the pathways for data to flow between the CPU memory storage devices and inputoutput devices Power Supply Unit PSU Fueling the System The power supply converts the AC power from the wall outlet to the DC power that the various computer components
