When we decide to buy a desktop or laptop computer the general norm is not to pay much attention to the type of screen display that completes the package. We figure its there so it should be all right. Not true! Though the monitor is one of the most important elements of the computer setup apart from the CPU we often overlook this aspect.
Buying a desktop computer at one time was a simple task – visit a showroom, select a model and pay for it; the computer is delivered and installed and that’s all there is to it. Today, you would be lucky if you even knew where to begin your search for the ideal desktop computer. Use the information in this article to guide you in your purchase.
You have decided you need a desktop computer, but before we begin looking into CPU performance and the right type of Hard Disk Drive you will need, you have to ask yourself the all important question “what do you need the desktop for?” because that is what determines the best buy for you.
Desktops are generally bought by people who want a computer at home to check emails and chat with friends, type up household budgets and track income and expenditure, or type up the occasional word file. You can easily get a low end system that will cost you around $500 to perform these tasks. If on the other hand you have specific needs, you can choose a high end model. Alternatively, you can upgrade storage and add a truly mind boggling array of features to the desktop. It is recommended that you buy what you need with the option to upgrade in the future when required.
In addition to speeds up to 10 megabits per second (albeit only over a fairly short distance of 40 feet) and a maximum connection distance of 4,000 feet, RS-422 can communicate in both directions simultaneously. And while the standard only allows for a single driver, there can be multiple receivers (up to 10). RS-422 systems need a dedicated pair of wires for transmitting and receiving, and also one for control signals, if required. Depending on speed, distance and the characteristics of nodes, termination (the matching of impedance between nodes and the line) may or may not be an issue in RS-422 systems.
Even if you are not a techie you can still ask intelligent questions about the motherboard capabilities and make sure that the one you buy has at least 2-3 USB ports in the front for your memory drive or audio player. Additional ports in the back will be helpful for attaching a host of additional equipment like printers and external hard drives. Color coded cables simply the setup and a high end audio and video output with Fire Wire ports should be part of the package. Ask about warranty and technical support, without the right warranty and less than adequate after sales support you will be in trouble. Make use of our guide to help you research the available models and make the right choice.
