QuickRing Architecture Could Revolutionize Data Transfer
The QuickRing architecture, announced last month at the Apple Worldwide Developers Conference in San Jose, Calif., could have a profound effect on many areas of high-end Macintosh computing, such as video processing and high-speed networking.
QuickRing is a communications system that lets plug-in NuBus cards exchange data with each other or external equipment at rates of up to 200 Mbps. This is more than 10 times faster than non-burst-mode speeds available in the existing NuBus architecture and opens the door to new applications that Mac developers could only dream of before…
'Fire Walls' Stand as a Protectant Between Trouble and the Network.
Large buildings are often built with fire walls—fire-resistant barriers between vital parts. A fire may burn out one section of the building, but the fire wall will stop it from spreading. The same philosophy can protect Macintosh networks from unauthorized access and network faults.
A network fire wall usually is nothing more than a router configured to prevent certain network packets from traveling between parts of the network. For instance, a router can partition off the machines in the R&D department, so other network users can’t access secret information. Some routers can be programmed to transfer electronic mail but restrict remote-terminal log-ons. And the chairman of the board’s laser printer could be hidden from the rest of the network, so the average user can’t print on that machine…
What is Happening to the Internet?
Recent changes to the Internet are turning the network of the military-industrial complex into the most likely prospect for an all-encompassing electronic-mail system.
Business cards used to be simple: name, company, address, telephone number and maybe a logo. Then came facsimile numbers. Now something with an @ in it is appearing on more and more business cards. It’s an Internet address; you probably have one already, although you may not know it, and sometime during the next couple of years you will have to learn it.
With an estimated 25 million users, the Internet is by far the world’s largest electronic-mail network, and its reach is extending to more private and public mail systems every week.
“If [people are] serious about electronic mail, I can get to them via the Internet; if they’re not, I probably don’t have time to figure out how to reach them,” said Bob Halloran, network manager at AT&T Co.’s Universal Card Services in Jacksonville, Fla…
Computer Security: Key Management Issue
MacWEEK Special Report: Emerging Technologies
Back when computers stood alone on desks, unconnected to the rest of the world, computer security was simply a matter of locking an office door, putting a lock on the power supply or installing a security software package. Today, the rules of computer security are changing, and in years to come, it’s going to be a whole new ball game.
What used to be the concern solely of the military is required by more and more companies. “Between LANs, file servers and dial-up connections, it’s hard to regulate who has access to what,” said Steven Bass, principal software engineer at Codex Corp., a division of Motorola Inc. in Canton, Mass…
