Andrea has a question about processor terminology and asks the following question: “I keep hearing about dual-core and quad-core processors. What does that mean and how will it benefit me?” Andrea, this is perhaps the biggest question when buying a new computer. Namely because changing the processor is like swapping the engine in your car. It can be done, but it’s a fairly expensive proposition.
Multi-core processors dominate the market for new PC’s. It used to be a single-core processor with a fair amount of speed would be adequate for most. However, as demand caused from software and operating systems increases processors have been designed to meet those requirements. Before I go any further, I think most people would benefit from a multi-core processor.
In the beginning of time computers used a single core processor which took a single stream of data and (for lack of a better term) processed it. Only one command could be jammed through at a time. If more than one event occurred then priority would be given to the first process until there was an opening in the queue or the first terminated. Until the last five years or so this was the norm and we were all used to waiting.
2005 marked a great time for those of us who demanded multiple applications and processes be run simultaneously. Intel came out with the first dual core processor for home use. Dual core processors allowed more than one application be run at the same time – greatly increasing productivity. Basically, twice the work could be performed when compared to a single core design. A few years ago the quad-core processor evolved and now the six-core is on the market.
Many people feel a multi-core processor isn’t necessary until they try them with standard applications. In a nutshell, even everyday users benefit from having at least a dual-core processor when virus scans or other normal background software is running. Think of it like having a second engine in your car that kicks on when the car becomes sluggish.
Dan asks, “My new computer doesn’t work with my old printer. Is there anything I can do?” Dan, from your e-mail I am gathering you have a fairly nice printer with a parallel printer cable and your computer only has USB ports. Unfortunately this is the case for a lot of people; however, it’s not insurmountable.
About three years ago computer manufacturers started limiting production of machines with legacy connections (serial and parallel ports) in exchange for USB connections. USB ports are universal so they don’t require specific connections and offer more locations to connect devices. The downside for consumers is that it requires purchasing new printers or other devices which have USB interfaces.
Several companies supply USB to parallel printer cables for under $10.00. I found a handful of them by searching the web for “USB parallel.” I have had mixed luck with USB converters for legacy devices due to the way devices are addressed (an article for another time). The best way to get connected is to use an internal card for your device. I found a bunch of them by Googling “PCI parallel.” Prices are a little higher; but, your chances of success are also higher.
Prior to making any decision I would suggest looking at the prices of new printers. I believe you can purchase a comparable one for slightly more than the price of the add-on card. New printers have the added benefit of better print quality and availability of supplies.
Tip of the week: Set aside some time every few weeks to back up your data and put it in a secure location.
