A: The basic composition of computer hardware1: Host (cpu+ memory)2:I/O (input or output devices) do not have a simple input or output device, all computer equipment (peripherals) are input or output devices! such as external memory.Two: the concept of software1: Software (can be expressed with instructions and data). These sequences of instructions are called "

Sometimes, our computer does not start properly, and it emits a different beep, which means that the computer is faulty and needs to be ruled out.
