HotSync is the registered trade name for a sophisticated method of linking between a Palm handheld computer and a more substantial notebook, desktop, or other computer. Such a link can be done using a so-called HotSync cable, or using a wireless connection. If the portable computer and the larger machine are in the same room, the link can use infrared radiation (IR).
Direct linking between computers eliminates the need for cumbersome disks or tapes when data must be copied from one hard drive to another.? But the versatility of the scheme goes beyond simple data transfer.? In a network, direct linking allows each portable computer to take advantage of the resources of the whole system, and also allows communication between or among end users.
