A modern computer has the following hardware components: input/output devices, processing unit, memory unit and secondary storage. The memory unit is the principal storage of the computer. All the data and instructions that the computer needs at a moment are stored here.The earliest types of memory were electromechanical relays, mercury-filled tubes and transistors. Now the memory is in the form of a semiconductor or silicon chip.A computer memory unit is the storage where data and instructions go when entered into the computer.Memory units nowadays are measured in megabytes; the usual computer may have 64 MB, 128 MB, 512 MB or more.
