the status of voting by interfacing the voting machine with the PC. For connecting the voting machine with PC we use the Hyper Terminal communication system‚ which are already come with the Window2000\XP operating system. A BRIEF INTRODUCTION TO 8051 MICROCONTROLLER: When we have to learn about a new computer we have to familiarize about the machine capability we are using‚ and we can do it by studying the internal hardware design (devices architecture)‚ and also to know about the size‚ number
