Project Guide – Build Your Own Computer – The Steps

- Taking stuff apart.

Junk computers are a great place to start, easy to find. Set up a table and take them apart. Don’t break anything, though, since computer parts are filled with toxic chemicals. Find a computer parts diagram on the Internet and learn the names of the parts.

- Studying about computer design.

There are a number of great books on building your own computer. Do a search on Amazon. Get at least two and read them. It’s always best to have more than one perspective.

- Interpreting drawings.

Study the diagrams, learn the parts. There are a number of custom computer sites on the Internet that let you play around with creating your own custom design – with the price. Google for one and come up with a variety of creations, both lowest cost and highest. That’s how you learn.

- Learning electronic circuitry.

It’s good to know how the circuitry works. Not necessary, but helpful if your goal is a larger, all-around knowledge of your computer. Look for a book on Amazon, or find an electronic circuit training kit.

- Troubleshooting a computer.

Work on a computer that is worth fixing. But there are principles of troubleshooting that must be learned. Search for sites that teach you how to troubleshoot. You can find books on the topic through Amazon as well. You can’t repair a computer until you know exactly what is wrong. And computers are their own world. Learning computer troubleshooting is where you start.

Web Design and Human Computer Interaction

Internet is an essential part of our modern life. It’s taking over a role in our personal and commercial life. Now we buy and sell online, bank online, socialize online and lot more. And when we talk about internet we talk about websites. Website is the media of communicating between human and internet. So it is essential for all the web developers to make sure the websites interact with its users and that is the key to success.

There are millions and billions of websites are online but only a few percent of them are successful. When a developer develop a website they have to follow certain rules which we call HCI rules.. Ben Shneiderman is well know among all the web designers for his “Eight Golden Rules of Interface Design”. But still in most of the websites the rules are exploited or not properly followed. It depends on web designer how their websites going to look like but the key thing and motive is to interact with the common users. So every websites have to feed the needs of the users and for that the following eight golden rules has to be followed carefully.

Strive for consistencies: The website need to have a clear and simple main menu. All the menu options have to relevant and consistent. The functions like links, drop list, command buttons etc has to be used wisely and carefully. Clear and relevant design interface should be used through out.

Enable frequent users to use shortcut: All the websites should be easy to use for the frequent users. The user should be able to access required information in one click. So navigation should be detailed and users should go to preferred pages straight away. Most the websites use Back links to return to previous pages or main menu. Read the rest of this entry »

The Pulse of Technology – Keeping Pace With Continuous Change – November, 1998

Gordon Moore, the co-founder of Intel Corporation first postulated the now-famous Moore’s law in the nineteen seventies. Moore’s law states that the processing or computational power of silicon chips will double every twenty-four months, while pricing for these chips will halve in the same time period. This law has remained relatively constant for over twenty years. We are now approaching a time when this seemingly immutable law is becoming outdated. In fact, new silicon chips are doubling in power; with new chips coming online within twelve to eighteen months, while pricing is being halved in even less time. What has happened to the underlying technology that drives these silicon chips, and what are the market forces that have dictated rapidly declining prices?

There are several factors that lead to the inexorable increase in processing power, just as these same factors exert a downward pressure on prices. Let’s look at several of these factors in the context of hardware developments, software developments and the rise of the Internet as the ubiquitous network that many people predicted as being necessary to make computers universally acceptable in daily life.
Hardware Development.

When Intel was founded by ex-Fairchild developers, the mid-range computer, as personified by the DEC PDP series, Data General machines, IBM 32/34 series and the first HP boxes was the emerging standard in the computer industry. Machines of this time period were often viewed as departmental machines that were required to perform quick, hands-on computing applications that were free from the centralized (i.e., mainframe computing environment) I.T. staffs of the time.
