- W26513439 abstract "On February 14, 1946, scientists at the University of Pennsylvania activated the ENIAC, the world's first programmable computer, which stood ten feet tall, stretched 80 feet wide and weighed 30 tons. The ENIAC could perform relatively basic math computations. Today, 50 years later, consumers can execute a wide range of applications -- from taking notes to browsing the World Wide Web -- on so-called personal digital assistants (PDAs) weighing as little as 1.5 pounds. Originally targeted at business professionals, these and other mobile computing have realized a widespread acceptance among educators. International Data Corp., of Framingham, Mass., predicts that shipments of smart handheld devices will increase from 1.5 million units in 1995 to 6.2 million units in 1999, with wireless communications driving the growth. This article provides an overview of the latest mobile and wireless products, with special emphasis on the implications for education. * Notebooks Slim Down One of the fastest growing areas revolves around notebook computers, which are now widely used by instructors and students alike, especially at colleges and universities. A main factor in this growth has been steady price reductions over the last six months. For example, Compaq recently lowered prices on its LTE 5000 family of notebook PCs by up to 28%. And, despite their small size, today's laptops in many cases pack as much power as their desktop counterparts. Hewlett Packard's OmniBook 5500 CT 5/133, shipping this May, integrates a 133MHz Pentium processor, 1.35GB of hard disk space and 16MB of RAM (expandable to 64MB). Reflecting an important trend, the OmniBook also offers a built-in 4 Mbps infrared (IR) port, for quickly transferring information to/from another portable or a desktop machine. Similarly, Farallon's AirDock plugs into the serial and ADB ports of a Macintosh, enabling IR-equipped PowerBooks to access files or network resources. MacUser selected AirDock as a 1995 Editors Choice Award Finalist for Best New Portable Computing Product. Observers also predict that CD-ROM drives will become standard in value-line notebooks, as will longer-lasting batteries and more modular options. In an independent test, the Dell Latitude XPi P120D operated an average of four hours and 21 minutes -- which should outlast even the most long-winded professor. For those looking at middle- to high-end models -- costing between $3,000 and $5,000 -- stay tuned for a new wave of ultra-slim notebooks, built with a unique footprint that allows for larger LCD displays and keyboards. While Apple's PowerBook remains popular in academia, the arrival of Windows 95 last fall has sparked a strong demand for notebook PCs designed for this new OS. Gateway 2000's Solo 120, for instance, ships in a Best Buy Configuration with Windows 95 and Microsoft Office 95. * PC Cards Catch On One of the most promising technologies for mobile computing is the PC Card (or PCMCIA). Frost & Sullivan, of Mountain View, Calif., reports that roughly 95% of laptops and notebooks will have PC Card slots by the end of this year. PC Cards can be fax/modems, Ethernet adapters, hard disks, memory and more. Their modular nature lets one add new capabilities to existing machines as needed down the line. Communications seems to be the most prevalent application for PC Cards. From Ositeeh comes the V.34 Jack of Diamonds, which works in conjunction with a cellular phone for wireless data transmission at speeds up to 14.4 Kbps. It utilizes the MNP 10EC protocol to reduce signal distortions. Recognizing the potentially huge market for wireless Internet access, telecommunications firms are moving quickly to expand related services. MCI recently extended local access coverage for its XstreamAir cellular service to 36 major metropolitan areas in the U.S. Sprint, meanwhile, is currently building an all-digital wireless calling network based on personal communications services (PCS) technology. …" @default.
