Virus Protection on the Mac is Simple But Necessary

  • December 13, 1993

"Protecting yourself from Mac virus infection is easy; it's a wonder there are people who don't do it," said Ben Liberman, independent Macintosh consultant in Chicago. There are several good anti-viral software packages, both commercial and free, designed to protect your Mac from attack.

There are two types of anti-viral software: protective and detective. The commercial virus-prevention software packages -Central Point Software Inc.'s Central Point Anti-Virus for Macintosh 2.0, Symantec Corp.'s Symantec Anti-Virus for Macintosh 3.5 and Datawatch Corp.'s Virex 4.1 - support both protective and detective protection.

Macs are used extensively in the sciences. Not just for writing research papers and creating presentation graphics but also for instrument control, data acquisition and analysis, and scientific simulation. There are many scientific applications available on the Macintosh - commercial, free and custom-built - and scientists all over the world are taking advantage of them.

The Mac is also commonly used in the sciences as a front end to high-end workstations.

Mac Development Tools Get With the Program

A computer platform is only as good as the software developed to run on it. To create good software, programmers need flexible development tools that take advantage of evolving hardware and operating systems.

Apple's interests lie in keeping development tools current so programmers will continue to develop for its Mac, Newton and PowerPC platforms. It has often received criticism from developers for delays and outdated tools.

Automatic Disk Compression Stirring Debate Among Users

  • September 6, 1993

Automatic disk compression programs promise to effectively transparently double the storage space on your hard drive. Although most can live up to this claim, several factors, including performance and reliability problems, have sullied the images of these products.

Given the prevalence of cheap disk drives, some doubt the wisdom of using these products at all. Many users report no problems, however, and have come to rely on automatic disk compression to squeeze every last byte out of their storage devices.

Emergency Recovery Tools: Raising Data from the Dead

  • June 21, 1993

Any user who has suffered a disk failure can attest to the importance of regular backups. No matter how vigilant a backup program you implement, however, a disk crash between backups can still destroy valuable data.

"You stress backups, but in most cases people don't do them," said Mark Goldenberg, senior development engineer at Hughes Aircraft Co. of Fullerton, Calif. "Or the file they destroyed or deleted is one they created that day." In situations such as this, emergency disk recovery tools can prove invaluable.

Everything's Coming up Packets

Public Switched Systems Are Becoming the Leading Edge in Wide-Area Networks

  • May 17, 1993

For many years, the only way for distant computers to communicate over the public telephone system was via a voice-quality link, either a dialup line or a point-to-point leased line. Big companies needed better connections, and several data communications standards, such as X.25, were developed to provide them on these lines. As networks expanded and applications required speedier transmission rates, time-division multiplexing (TDM) technologies stepped in to provide cheaper and faster data transfers on large-bandwidth circuits, often making it cheaper to lease a dedicated T1 line than to run several low-speed lines.

Packet Trio

In recent years, increased transmission rates, moreintelligent network equipment and cleaner transmission lines have spurred the growth of packet-switching technologies.

Inside the PCMCIA Storage Standard

  • January 11, 1993

Originally a nonvolatile storage standard, PCMCIA has grown to be a much more versatile interface. With its small size and low power draw, it has gotten a lot of attention from computer developers looking to reduce both bulk and power on their portable products.

Apple is evaluating PCMCIA for its PowerBook line, and Newton will ship with a PCMCIA slot; the slot also will support an Apple-proprietary 32-bit bus called TrimBus. Using PCMCIA, users can plug in cards containing everything from interactive maps to network connectors.

A PCMCIA card is a removable device about the size of a credit card (2.126 by 3.37 inches).

Flash Memory Offers Potential for Compact Storage Solution

  • November 16, 1992

While many types of removable media are good for long-term storage, they are often too bulky and expensive for compact devices such as printers, palm-size computers and network hardware.

That's why a growing number of vendors are swinging over to flash memory, also known as flash ROM, a form of nonvolatile memory that blends the rewrite flexibility of dynamic RAM with the permanence of ROM.

Though not a silver-bullet solution for all memory requirements, flash memory currently works well for storing a few megabytes of printer fonts, software or configuration data and has the potential to store much more.

"Any time you've got built-in code that's likely to change, flash ROM is an excellent solution," said Janet Woodworth, marketing communications manager at Intel Corp. of Folsom, Calif.

Removable Storage Keeps on Track toward Faster Access, Bigger Capacity

  • Bruce Schneier
  • MacWEEK
  • November 16, 1992

Since 1984, RAM capacity has climbed more than tenfold, from 128 Kbytes to 256 Mbytes. CPU power also has increased dramatically, from the sluggish 8-MHz 68000 to the 33-MHz 68040 in the Quadra 950.

Yet, the capacity of floppy disks - that almost ubiquitous storage media - has lagged far behind the others, barely tripling from 400 Kbytes to the current 1.4-Mbyte disks.

Desktop publishing, digital photography, multimedia and CAD all have put pressure on vendors for storage media that is much larger than floppy disks.

Remote-Link Details Matter: Gatorlink Vs. LanRovers

  • October 19, 1992

Both Shiva Corp. and Cayman Systems Inc. are readying multiport Ethernet remote-access products for shipment sometime this fall. At the Boston Macworld Expo in August, Cayman announced GatorLink and Shiva demonstrated LanRover/E. Shiva's LanRover/L, a single-port LocalTalk remote-access product, has been shipping since April. Both the LanRover/E and the GatorLink are hardware devices that connect AppleTalk Remote Access users directly into the network without the need for a dedicated Mac.
