In this paper there has been implemented a web server which store web pages on a microcontroller chip. To create a web server which connect to internet, TCP/IP protocol must be implemented as a software in the microcontroller system which use as web server. Protocols in TCP/IP which implemented are Serial Line Internet Protocol (SLIP), Internet Protocol (IP), Transmission Control Protocol (TCP), Internet Control Message Protocol (ICMP), and Hypertext Transfer Protocol (HTTP). Microcontroller connected physically to internet with use external V90 modem, so it is necessary to develop modem hardware interface and modem driver software. The benefit of this Embedded Web Server system compares with available systems on the market is that the TCP/IP protocol located inside the microcontroller as a software, so its realization can be cheaper and more compact, because it is not necessary to use TCP/IP chip to connect the microcontroller to internet.
