Transmission Control Protocol/Internet Protocol (TCP/IP) is an industry standard suite of protocols that is designed for large networks consisting of network segments that are connected by routers. TCP/IP is the core protocol suite that is used on the Internet.
Many TCP/IP application protocols were designed to access and transfer data between dissimilar systems. These protocols include HTTP, FTP, and Telnet. TCP/IP components in Windows allow standards-based connectivity to other operating system platforms.
Microsoft Windows Server 2008 R2, Windows 7, Windows Server 2008, and Windows Vista include a complete redesign of the TCP/IP protocol suite. The TCP/IP redesign supports both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) to meet the connectivity and performance requirements of today's networked environments.
