HTTP and the Web are a case in point. Static hosts are connected to wired, high bandwidth networks, and are capable of transmitting and receiving large amounts of data without significant delays.
Mobile computers are also relatively resource-poor, compared to their desktop counterparts.
This fact is ignored by HTTP servers, and large data files are transmitted to computers that cannot properly display them. Also, mobile computers operate in constantly changing network environments. It is possible for a mobile computer to become temporarily disconnected from a network when it changes base stations or goes out of range of a base station. A mobile host may also doze off to preserve battery power and thus be disconnected. The information browsing system and protocols assocaiated with mobile computers should thus be able to tolerate the fault of temporary disconnection.
