to make a network function when using the NetBEUI protocol (Whitehead 128,129).The disadvantage of NetBEUI is that it can only support 254 individual computers on a network. NetBEUI is also non-routable, therefor, a device on a NetBEUI network can not access a device on another network. However, segmenting a NetBEUI network can be accomplished by using a bridge because bridges use hardware addresses to determine the destination of data. Another disadvantage of not being a routable protocol and not using an IP address for addressing is that computers can not use NetBEUI to access the Internet. Also, NetBEUI offers absolutely no security. Any computer on the same segment of a NetBEUI network can access that network if the NetBEUI protocol is loaded on that computer. Because of these problems, NetBEUI is becoming less popular is recent years and is being replaced by TCP/IP (Dean 82,83). TCP/IPOver thirty years ago, the United States Department of Defense needed a protocol to run its networking needs. So TCP/IP was developed to handle those needs. Since the development of TCP/IP, it has consistently been upgraded, but the majority of the TCP/IP protocols in use today are the same as the protocols developed in the late 1960s. TCP/IP became a popular protocol stack due to the fact that the devices manufactured for the Department of Defense had to run on the TCP/IP protocols. The companies that built these devices for the government also sell the devices to the general public. The Internet has also had a profound effect on the acceptance of TCP/IP because the Internet runs on TCP/IP (Whitehead).TCP/IP is broken down into two unique underlying protocols, TCP and IP. TCP stands for Transmission Control Protocol and IP stands for Internet Protocol. Subprotocols of TCP/IP include User Datagram Protocol (UDP), Address Resolution Protocol (ARP), Internet Control Message Protocol (ICMP), Domain Name System (DNS), File Transfer Protocol ...
