Bad sides of computer

Small here, also meant something that would comfortably fit into a couple of 6 foot electronics racks! You and your kids shared the single TV and the Flintstones often won out.

The Commodore 64 would never have been as successful as it was if an expensive monitor were required rather than an option. However, as computer performance improved, it quickly became clear that a dedicated display was essential. Even for simple text, a TV can only display 40 characters across the screen with any degree of clarity.

It was bright, crisp, and stable. This was really fine until the introduction of Windows well, at least once Windows stayed up long enough for you to care.

All of these displays used digital video - TTL signals which coded for a specific discrete number of possible colors and intensities. Both the video adapter and the monitor were limited to 2, 4, 16, or a whopping 64 colors depending on the graphics standard.

The video signals were logic bits - 0s and 1s. In principle, an analog monitor is capable of an unlimited number of possible colors and intensities. In practice, unavoidable noise and limitations of the CRT restricts the actual number to order of distinguishable intensities for each channel. Note that analog video was only new to the PC world.

Notes on the Troubleshooting and Repair of Computer and Video Monitors

In all fairness, both the display adapter and monitor are more expensive so it is not surprising that early PCs did not use analog video. Most of the information in this document applies to color computer video monitors and TV studio monitors as well as the display portions of television sets.

Black and white, gray scale, and monochrome monitors use a subset of the circuitry and generally at lower power levels in color monitors so much of it applies to these as well.

For a fixed frequency workstation monitor, studio video monitor, or closed circuit TV monitor, only a subset of the possible faults and procedures will apply. Usually, this refers mostly to the horizontal frequency as the vertical refresh rate is quite flexible on many monitors of all types.

Multi-scan monitors sync at two or more distinct scan rates. While not very common anymore, multi-scan monitors may still be found in some specific applications. Related Information See the documentss: Since a monitor must perform a subset of the functions of a TV, many of the problems and solutions are similar.

For power related problems the info on SMPSs may be useful as well. If you are considering purchasing a monitor or have one that you would like to evaluate, see the companion document: Performance Testing of Computer and Video Monitors. Monitors designed for PCs, workstations, and studio video have many characteristics in common.

Modern computer monitors share many similarities with TVs but the auto-scan and high scan rate deflection circuitry and more sophisticated power supplies complicates their servicing. However, handheld equipment, laptop computers, and the screens inside video projectors now use flat panel technology, mostly Liquid Crystal Displays - LCDs.

These are a lot less bulky than CRTs, use less power, and have better geometry - but suffer from certain flaws. As the price of LCD and other technology flat screen technology decreases, such monitors will become dominant for desktop computers as well and CRT based monitors will eventually go the way of dinosaurs, core memory, and long playing records that dominated their respective industries for decades but eventually yielded to fundamentally new technology.

However, there are still problems with low cost, at least LCD monitors. First, the picture quality in terms of gray scale and color is generally inferior to a decent analog monitor.

The number of distinct shades of gray or distinct colors is a lot more limited. They are generally not as responsive as CRTs when it comes to real-time video which is becoming increasingly important with multimedia computers.

Brightness is generally not as good as a decent CRT display. And last but not least, the cost is still somewhat higher due both to the increased complexity of flat panel technology and lower production volumes though this is certainly increasing dramatically.

It is really hard to beat the simplicity of the shadow mask CRT. Only repair of the most simple problems like obvious bad connections, a bad cable, a bad backlight lamp, or a failure of the power supply or backlight inverter, can realistically be accomplished without fancy specialized test equipment and facilities.

Access to the backlight lamps might substantial disassembly. Buying a broken LCD monitor to repair may have better odds than the State Lottery, but probably not by much. Loose connectors and solder joints are possible, though not nearly as common as with CRT monitors.Key to Document.

Congress, House of Representatives; Joint Hearing on Educational Technology in the 21st Century. The Web is not very organized and this may offer a point of frustration for children.

However, at the same time, it also enhances their research and organizing skills. Nowadays, computer is a indispensable thing, no because you can play games with them, but people use computer to work, study, communicate,etc.

What our children are busy doing behind the computer and on the Net these days should be even more worrying to the authorities concerned and Ghanaians as a whole.
