  • The Technology In A LCD Monitor  By :
    Liquid Crystal display or LCD monitor is a thin and flat device for display. It is made by large number of color or monochromatic pixels which are arrayed in way of a light source or a reflector. It uses very small amount of electric power and hence is used often in battery powered electronic devices. The technology used is very much dissimilar to CRT technology which is used by many desktop monitors. It was used only on notebook computers for a very long time. Only recently ...

  • Early Vintage Computer Buses Have Their Influences On Your Computer Today  By : Art Fellon
    The term “expansion bus “is a frequent term in vintage computer terminology which requires elaboration. Much of the legacy of vintage bus systems are in our current computer systems today.

    To begin with the “expansion bus" is a data highway for computer data information to travel on: the bandwidth is in essence the number of lanes. The bigger the bandwidth the more data can be sent. As examples, an 8 megabyte bandwidth means that data can be sent in 8 bits chunks. Our curr...
  • Fall Time Sizzle Brings Blackouts, Sags And Spikes To Your Computer Systems  By : Art Fellon
    Why tempt fate?

    Fall Time weather as well as summer time can not only zap your newer computer systems but also your vintage computer as well as irrereplaceable vintage computer software as well as the time and energy spent in setup, hardware replacement and running computer systems.

    Why does the summer season bring so much trouble – brownouts, sags and electric currents spikes?

    Summer heat does wonders. Not only does it allow you to acquire a lovely tan but if causes...
  • The History Of Microcomputers  By : William Piker
    The history of microcomputers does not compare with the history of ancient Mesopotamia (Iraq). Microcomputers (now commonly held as PCs) have been around for only 25 – 30 years.

    It is good to have some knowledge of this history both to give some perspective of where we are today and to know where a number of our basic computer standards that we take for granted – as if they came from heaven, originated.

    The very first microcomputer machines were as exciting as a do-it y...

  • Third-Party Hardware Maintenance vs Manufacturer’s Warranty: What’s Best For Your Business?  By : Clive Seagrave
    When purchasing computer hardware for your business, system availability is a major consideration. While you hope it will remain reliable, you need to manage the risk that at some time a critical system component will fail, calling for hardware maintenance.

    Such failures often result in the system being unavailable to users until repaired. This ‘system down-time’ can be very costly when users sit idle and unproductive.

    Many assume that the standard manufacturer’s warran...
  • Repair Your Computer For Free  By : Russell Snapper
    I just read an article about a lady whose computer was deluged by adware. It was such a problem that she spent thousands of dollars on computer repair fees to try to clean up her computer. The said thing is that she could have restored her computer by herself in less than a few hours and for free.

    Somewhere down the line, there will be problems with your computer (adware, spyware, viruses, good software gone bad, etc,). Obviously, you should use protection software to prev...
  • Become Your Own PC Repairer  By : Ken Charnly
    If you are like me, you have probably owned quite a few personal computers. You are sure to have had the occasional problem, and rushed the machine off to the repair shop. At the time, the cost of repairs may have seemed a bit high in proportion to the original cost of the machine, and you might not have been quite sure what was actually done.
  • Accessory Computer  By : Danny Wirken -
    A home away from home is a great thing, so why not have an office away from the office too?The spare room or a quiet corner can be a perfect place for productivity. To outfit your workspace, you might need to invest in some new hardware like a second computer, a bigger monitor or a high-quality printer. Once you've got your home computer set-up, you'll need to connect it to the Internet or network it to other computers and peripherals in the house. With a good grasp of the fa...

    You have tried and tried to get your speakes to work. You have the sound card and the speakers; so what is the problem? The first step is to check the connections. Most people accidentally plug the speaker jack into the Line-in Jack of the sound card. Check to see if this is what you did. If you have amplified speakers, make sure that the ...
  • The Ongoing Transition Of Hardware  By : Paul Babs
    Before the 1970s the word “hardware” usually meant one of two things: the beautiful chrome handles on your new dresser and the kitchen cabinets, or the hammer, saw, and nails that you purchased at the local hardware store. Then came the computer boom! Hardware took on a new meaning! If all the programming that made a computer work were called software, then the hard box and its components took on the name of hardware.

    Hardware became a massive, competitive industry that ex...

    Router is a computer device that receives or forwards data packets to and from the Internet towards a destination in the process called routing. Router is the essential component of the computer networking that enables any sent data to arrive at the right destination.

    As an illustration, imagine that the Internet is the world and one computer is one household. Other computers connected through the Internet are households around the world. Say one household will send a let...

  • History Of The Computer; Analog Or Digital?  By : Tony Stockill
    In 'History of the Computer - the emergence of Electronics', we saw how the development of Radar during the second world war led to an understanding of pulse technology. At the same time methods were refined for the calculations required for the ballistic trajectories. From these beginnings, the digital computer was developed.

    What is meant by 'Analog' and 'Digital'? A couple of examples will explain the difference. An analog is something which is analogous, obviously, but...
  • History Of The Computer; The Emergence Of Electronics.  By : Tony Stockill
    The history of the computer inevitably includes the development of electronics, we look at the explosive (!) growth of electronics in the late 1930s and early 1940s.

    If anything could be said in favor of war, it may be that it speeds up the development of technology. Of course much of that technology is employed in killing people and destroying infrastructure, but there are also things which could be considered beneficial.

    Electronics was around in the early part of the...
  • Mouse Hunt – Not The Movie (Choosing The Perfect Mouse For Your Computer)  By : Ismael Tabije
    Computer Mouse – it’s something you wouldn’t run away from. Instead, it is the one thing you would search for. In fact, every body is in search for a good one. And it has actually become a not-so-easy task to “hunt” for a good mouse – for your pc.

    What do you look for, when you say “good computer mouse?” Often, when you buy a whole pc set, a mouse is already included. But there are others who still search for a good one.

    In choosing a mouse, you must consider its compa...
  • Laser Machine Welding  By : Peter Vermeeren
    Laser machine welding is the joining of two pieces of material, usually metal, but often these days plastics, using a laser beam. A laser is a single phase, or coherent beam of light often seen in science fiction movies, but the development of the laser beam and its application in laser machine welding allows for advancements in precision welding using this high-energy device, which creates heat when it strikes a surface. Laser machine welding is used for steam tracing and in...
  • Professional Help With Your Computer May Be Cheaper Than You Think  By : D. David Dugan
    We all deal with them, those little computer problems that aren’t quite big enough to warrant a call to the Computer Guy. You know, like every once in a while your camera won’t transfer its pictures the right way. Or like the times when all of a sudden your computer shuts down for no apparent reason and with no warning whatsoever. Don’t forget those odd “Run Time Errors” with the crazy numbers in them. I love those.

    The worst part is, you could probably fix some of these...
