A slow running computer can be irksome for anyone. Why at times our PCs are robbed of their efficiency? Well! It can be anything, hardware or a software issue. Physical parts of the computer, for example CPU, keyboard, RAM, monitors constitute computer hardware. On the other hand, all the programs and applications that are installed on the computer are software. Software programs are abstract that we cannot touch. Any error in computer hardware or software can spoil your PC’s productivity and make it dead.
