Computer Technology - Is it Good Or Bad?

The 21st century has been the age of so many technological breakthroughs and advances, technologies aimed for one purpose and that is to make the lives of people better by helping them become more efficient in their work. One such technological breakthrough is computer technology.
Computer technology has grown in great proportions starting from a computer with a size that of a room to a small well-designed palm top computer. Computers nowdays have become an indispensable part of the lives of people, especially at work, at companies, businesses, schools, offices and even in homes.
It has made the world smaller, but has it made our world better? It would then lead us to ask whenever computer technology is good or bad. Now let us try to look at first some of the bad effects. With the advent of computers and with the internet it has become easy to access pornographic sites, children are more exposed to explicit content; Some students would lose focus on their studies as they play computer games. The number of obesity cases has increased and it has been attributed to too much computer activity that led to less physical activity among a number of people.
On the other side of the coin, computers have opened a whole new world of possibilities. It is now easier to gain information on world events; You can even find a job in the internet; You can spread advocacies to a vast number of people all over the world; And most importantly it is now easier to be connected with one another even if you are on the other side of the globe.
Computer technology, just like any other material on earth has been created with a common good in mind. Just like a knife, it has been made to cut and slice food to speed up cooking time for people but it can also be used to kill people, and you can not ban the use of knives in order to stop killing. And so you can not blame computers for the problems it may have caused for it is the people who use them who caused the problem. It has disadvantages and advantages that must be taken into consideration.
But the problem is not computer technology itself; The problem resides on the people who use it. Computer technology is generally good for it can bring in a lot of good if it is used properly, but can do great harm if used unwisely.
People have choices on how they make use of earth's resources, and that choice will determine how certain materials will affect people, be it good or bad.

Parameters to Measure the Performance of Computer Monitors

A monitor, also known as display is basically an electronic visual display for computers. Three primary components of the device include a circuitry, enclosure and the display. As far as the display device is concerned, it is basically a thin film transistor liquid crystal display in most of the modern monitors. The monitors available in the past used a cathode ray tube.
The demand for these latest devices in the market is increasing with every changing day. To meet the requirements of the users, more and more brands have started launching user-friendly gadget furnished with innovative features and state-of-the-art technology. Some of the leading names in the domain of monitors include Panasonic, Samsung, Sony, etc. The gadgets introduced by these brands are known to offer an exceptional performance even home as well as office.
As far as the performance of the device concerned, it is measured by the following parameters:
Luminescence
The unit for measuring luminescence is Candelabrum per square meter.
Aspect ratio
It is another important parameter for measuring the performance of the gadget. It is defined as the ratio of horizontal length to the vertical length. The aspect ratio of the device can be 4: 3, 5: 4, 16:10 or 16: 9.
Display resolution
It is defined as the number of distinct pixels occurring in every dimension, which can be displayed.
Refresh rate
It is defined as the number of times for which a display is illuminated in a second. The response time limits the maximum refresh rate.
Contrast ratio
It is defined as the ratio of the luminosity of the brightest color and the darkest color produced by the monitor.
Viewing angle
The maximum angle at which an individual can view the images on the monitor without the extreme deprivation to the image is called viewing angle. It is mainly measured in degrees vertically and horizontally.
These are some of the essential parameters to judge the performance of the gadget. The perfect medium to grab the best computer monitors is the internet. The medium proffers a vast collection of products available at cutthroat prices. In addition to this, customers can also enjoy exciting offers and deals on a wide range of products. The price comparison tools of several online shopping portals can also enable individuals to compare the price and feature list of a majority of products and brands. Apart from monitors, you can also find other electronics at one such store like mobile phones, all professional camcorders, digital cameras, etc.

The 4 Elements That Makes Up A Personal Computer System

There are 4 elements that make up a personal computer system: the user, software, hardware and the electricity all working together for the whole system. Each of these elements is essential to the system itself.
The user is the person's who perform the task using the computer system. The nature of the task depends upon the application program or software that is needed to perform the task. The software that the user used requires certain hardware components to function properly.
The hardwares of the personal computer system are made up of its equipment that are usually connected (the computer, monitor, printer and so on). It is defined as hardwares because you can physically touch these components. The programs are called softwares since their function can only be used when the computer is turn ON. Software is a set of coded instructions that the computer uses in order to carry out the user's tasks.
The user can only use the computer when it is turned ON. Without any electrical power to run through the personal computer system, it will not function. The ability of the personal computer system to control its components is through a series of on / off signals.
Here is how it works, when a user tries to type a document or a letter using his / her personal computer. The first thing the user do is to turn ON the power for the computer. Choosing a Word Processor software in order to write the document. The user uses the hardware such as the keyboard to write the content of the document; The typed document is then displayed onto the monitor screen. After the user finished writing his / her document. The user will use the software to instruct the printer to print the document. The software works together with the hardware components (the keyboard, monitor and printer) to accomplish the task that the user requested.
All of the four elements: the electrical power, hardware, software and the user work together to make up a personal computer system.

7. Development of New Hardware - New hardware products appear in the market frequently that revolutionize your computer experience and are based on newly developed technology. The chances of your old computer supporting new devices are very low.
8. Faster Devices - Your old computer may not be in a position to accommodate the speed at which the new devices communicate.
9. New, Fast Communication Protocols - You may not be able to implement new or faster communication protocols in your old computer because the hardware is unable to support them.
10. Operating System and File Format - Your old hardware may not be able to run newer operating systems and some of the file formats may not be supported.
