Evolution Of Computer Technology

Today computers are an indispensable part of the lives of human beings but at one point of time there were no computers. Knowing the history of computers and how much progress has been made can aid us in understanding just how complicated the invention of the computer really is. Unlike other devices, the computer is the one invention that does not have any one specific inventor. Throughout the development of the computer, various people have made contributions to making a computer work. Some of these inventions were those of complete computers or other additions that helped revolutionize the computer that existed at that time. One such invention was the Integrated Circuit.

The single most important year in the history of computers is 1936. It was in 1936 that the very first computer was created by Konrad Zuse who called it the Z1 Computer. This was the first system that was fully programmable. Even though there had been devices that had come and gone before this but they didnt match upto it because of its superior computing power. Till 1942 no business saw profits and opportunities in computers. The first computer company was called ABC computers and was owned and operated by Clifford Berry and John Atanasoff. Two years later in 1942 came the Harvard Mark I computer which furthered the science of computing even more.

The age of computers saw its biggest change ever in 1953 with the introduction of International Business Machines known today as IBM. The company has always been a key player in the development of new systems. This was the first real competition to bee seen in the world of computing and helped to encourage faster development of better computers. The first contribution of IBM was the IBM 701 EDPM Computer. A year after this the first high level programming language was brought to the centre stage. This was a programming language that had not been written in ‘assembly’ or binary languages and was called FORTRAN which was written to enable more people to be able to program computers. In the year 1955 Bank of America, Stanford Research Institute and General Electric joined hands to introduce the very first computer for use in banks.

After that the evolution was quick. Computers like Apple I and II, The Scelbi, Mark-8 Altair, TRS-80, the Commodore Pet computers and IBM 5100 were the leaders of the sector of home computing. The micro processor was like the heart of the computer and began with the Intel 4004. from then it has evolved into todays Pentium IV, Dual core and Core 2 Duo processors. Along with the evolution in Hardware came the evolution in software which went from assembly languages to todays languages like C++, Java and PHP. There is more to come in this field and that more will surely be AI or Artificial Intelligence. The term was coined by John McCarthy and is today a major field of study.

Computer Chairs For Fat People

As much as youd like to deny it, our lives change when we become overweight. Computer chairs for fat people arent just a gimmick, they are a real necessity. If youve ever had a computer chair break under you, you know exactly what Im talking about. Chances are, if you weigh more than the 200 lbs that average chairs are designed to support, you have been dumped on the floor at least once by an office chair that just didnt hold up properly.

Fortunately, there really are computer chairs for fat people, designed with wider, heavier bodies in mind. These chairs are created with metal cores to prevent those embarrassing incidents where a leg snaps off and leaves you sprawling on the floor.

Being overweight is rarely a choice. You may be working very hard to lose weight, but in the meantime, you dont want to be breaking every chair you buy after just a couple of weeks. Thats why you should consider investing in sturdier, stronger computer chairs that will hold up under more weight.

Not only are computer chairs for fat people built to withstand more weight, they are also built to help you sit in the right posture and to give your body the support it needs. You see, our backs tend to be in pretty bad shape thanks to the extra weight we carry around, so it makes sense that we would need that extra lumbar support. Stay away from chairs that arent ergonomically correct, since they will only mess your back up more.

Choosing a computer chair shouldnt be rocket science. Look for one that has metal in all the important places and that offers back support. You should also check the weight limit. While some heavy office chairs are designed to hold up to 300 lbs, there are some specialized chairs that will easily stand up to 500 lbs and are virtually tank proof. This is what you need if youre heavier and want a chair that will last a little longer.

Unfortunately, these heavier chairs are more expensive than your average office chair. However, youll be able to use them for a very long time, since the legs and arms wont snap off like the usual cheap office chairs. Its a long term investment that will really pay off. You wont have to keep buying those darn breakable chairs and youll avoid the humiliation that comes with breaking chairs.

Computer chairs for fat people really are worth it. You can avoid a lot of pain and embarrassment just by investing a bit more in a chair that is actually built to hold you.


Running Two Projectors With One Computer

For some occasions, you might want to run two projectors by using one computer in the same time. In this case, you should know that some computers will allow you to simultaneously plug multiple projectors. This is because those computers especially desktops have two video graphics array connectors.

However, you might have computer that does not have the dual VGA connectors. For this condition, you should purchase a VGA splitter. This equipment will divide the signal to allow you playing the graphics through tow projectors that you have. With this way, you will find that the image that you will get is not as clear as that you want. But, you will find that the difference is barely noticeable if you only split it once. The followings brief description on how you can run two projectors with one computer.

Firstly, you should purchase a VGA splitter. This is the most first thing that you should do. You can buy this equipment in the electronics supply stores in your area. The price for this equipment is a about $10 to $20 or more.

Secondly, you should connect the VGA splitter that you have purchased to the VGA port in your computer. You will find that the port for VGA is generally blue and it has 15 holes for pins.

Thirdly, you should use split wires to connect the projectors. For this, you should use VGA cables that appropriate with your projectors. If the input of your projectors is also a VGA port, you can use a cable with a VGA plug on one side of the cable. But, you should use a plug for VGA with three prongs output if you use a component projector.

Fourthly, you should power on your projectors and your computer before calibrating the projectors. You will find that calibrating your projectors will depend on the specific projectors that you have, but you should set the input before running it through the computer that you use.


Functions of Device Drivers For the Hardware and Software Components

However, device drivers are coded differently for conforming to the requests of the application and the features of the hardware component. >

Device drivers act as programs tasked to translate application or user requests into a form comprehensible to the hardware. Despite the diversity of features coded directly into an application, it does not contain the necessary procedures that can allow it to directly relay its requests to a hardware device.

They are programmed to receive related software requests for using the features and functions of the corresponding hardware device. These requests usually take the form of high-level codes from a programming language used in the creation of the software.

Device drivers subsequently convert such related application or user requests into machine language or codes comprehensible to the hardware component after it receives the requests. The result would be the implementation by the hardware device of the related application or user requests.

A programming language called Assembly has the capability to directly tap into the functionality of a device. However, it is not compatible with the design and complexity required by user’s for high-end applications.

A simple example of such device driver activity is when a user tries to view a music file using a third-party application such as Windows Media Player. The media application then relays the user’s instructions to the sound device through the use of the audio device driver. The user can subsequently view the audio data contained in the music file through the speakers or headphones attached to the sound card of the machine.

Hardware devices also require the capability of device drivers to provide users with the ability to directly manipulate its functionality. Aside from using a third-party program to achieve this, a user may change the settings and configurations of a hardware device using its respective drivers. This is usually the case of display and sound devices installed in the computer.

However, the correct device drivers need to be installed before a related application or a user can manipulate a hardware device and use its bundled functions or features. One should always consider these factors when installing the correct drivers for a particular hardware device: the version of the operating system used; manufacturer of the device and the model or make of the hardware component.

How is 3D printing technology used in Architecture and Medicine

D printing technology is used to manufacture prototypes, tools, and end-user parts directly from a CAD design. This printing technology offers unprecedented flexibility as it can create a part of any dimension out of any material. Some of the 3d printing materials used include metals, polymers, ceramics, composites, and many more. The 3D printing technology has complete control over material composition, surface texture, and micro-structure of the prototype. 3D printing technology also allows the user to construct prototypes using two different materials. >

Lets take a look at this amazing technology and how it has affected the field of architecture and medicine:

3D printing for Architecture

Architects know that there is nothing like a physical model of a building when it comes to displaying their work or design concept. Physical models also play an important role when it comes to explaining and convincing the customer while selling a project.

3D printers are affordable and high quality solutions for architects. Building a physical model requires great deal of expertise, precision, and time. 3D printing machines help designers focus on their building design, while the devices make 3D models of the project.

Many architects are not tech-savvy and are not used to operating complex devices. 3D printers do not require human intervention at any stage of the printing process. Architects just need to need to draw a CAD diagram of the project and instruct the 3D printer to build a 3D model. The 3D printer can print the model within a few hours, which can then be presented to the client.

3D printers are capable of producing of 3D models with accuracy and speed without compromising on the finer details of the architectural project. The price of desktop 3D printing machines is not that high and independent architects can also afford them.

3D printing for Medicine

The application of 3D printing technology can also be found in the production of medical devices. There are different 3D printing materials available that can be used to build real parts. For example, manufacturing hearing aids is a complex process because they are custom-fit devices and cannot be mass produced. 3D printing greatly helps in such matters where medical devices need to custom-fit a patient.

The future of the 3D printing technology is very bright. Market experts state that 3D printing technology will be affordable to the masses by the next decade. The prices of 3D printing devices are falling rapidly, and it is believed that the prices of 3D printers will drop by as much as 80% in the next 5-10 years. It will not be a surprise to see 3D printing devices in each household just like refrigerators, washing machines, and televisions.

Automated Forex Robots – Why Professional Traders Don’t Use Them

I have been a broker, worked in a fund management house and educate traders and I can tell you in my 25 years of trading experience, I have never seen any serious trader use the few hundred buck robots that are supposed to lead you to success – Why? Because they don’t make money…

Of course if you look at there track records of must Forex robots they have better track records than the world’s top traders who are on multi million pound salaries and yet, many robots claim you can double your money every month and all for the price of a night out. The reality of course is they never deliver and the reason is obvious.

They lose money!

The track records are either back tests, (in simple terms this means made up knowing the closing prices) or presented by the vendor themselves with no independent verification, no audit by a third party is ever presented. Hardly inspires confidence does it?

All Hype and No Substance

The hype in the copy is that you can make money in your sleep, while your playing golf or having a beer, simply switch the computer on, leave it and make money – but if this were true, the whole world would be trading and no one would bother to work.

In Forex trading lets make a point clear – you don’t make money easily! 95% of traders lose and in the case of the cheap Forex robots it’s 100%

The robots are all supposed to have been devised by whiz kids, nerds or insiders and one site I know actually took a few of the well known “traders” and showed where they had come from, a site of actors!

The systems present unrealistic gains which even Warren Buffet couldn’t match and traders believe them.

Sensible people suddenly become blinded by greed. Now lets look at how to make money and what you have to do.

How to Make Money In Forex

Serious traders know that like in all areas of life, you have to learn skills and learn to apply them with discipline. They don’t buy into the myth that Forex is a walk in the park – because its not.

Cooling a Server Room the Cost-Efficient Way

As the servers are used constantly, they generate tremendous heat. When this heat increases beyond control, it may lead to damage of the devices and equipment. Being machines, the computers are delicate under the hood and are prone to damage due to carelessness. System crashes, reboots, hang-ups, untimely failures; poor performance and other problems can be created due to abnormal temperatures. Now, one way to keep these issues under control is to maintain the server room’s temperature. Sufficient ventilation, cooling and maintained temperature are the efficient ways to protect computers and servers.

Maintaining the temperature

The computers used at homes and for small offices come with internal cooling devices, which usually keep the desktops and laptops cool. Nevertheless, the server rooms that manage a number of systems do not have sufficient internal cooling systems. They have to be kept cool using an external cooling source, such as portable air-conditioner. Secondly, increased humidity inside the enclosed area can cause corrosion or rust. The maximum humidity level of a server room should not exceed 40 to 50 percent.

Are portable air conditioners good solutions for cooling?

The temperature of the server room should be steadily cool around-the-clock. If the room or storage area is connected to the central cooling systems, they may be shut down during the weekends or sometime late at night, depending upon the company’s working hours. If the cooling systems fail, the computer systems are prone to face the brunt.

Portable air-conditioners keep the server rooms cool, as the temperature can be controlled individually depending upon the outside temperature. There are few air-conditioners that adjust the temperature according to the outside temperature on certain modes. They are self-contained units which do not require permanent installation. Business owners can move these units anywhere as required.

A portable AC used in such places must have condensation tank to manage the humidity level, automatic restart function and proper ventilation to replace the hot air inside the room. These features not only keep the servers cool but also regulate fresh air and keep the machines working continuously. The automatic function keeps the air conditioners working continuously even when there is a power cut or failure.

When it comes to the size of the air conditioners it is never an issue. The server closet of size 9000 to 12000BTU will be sufficient for the unit to fit in. While a 12K BTU unit requires 9 to 12 amps a huge unit of 14000BTU requires 20 amps. The air-conditioner should be thoroughly checked for the necessary requirements before installation.


All you need to know about Java programming before you stat learning.

Java is most admired language today if we talk about the project and application development point of view. The main reason behind the popularity and success of this language is that it has three main features namely

Portability

Security

Cross platform compatibility

The three mentioned feature which are the complex need for any application developed today wither that be a system application, mobile application or a short program that runs washing machine. Its easiest and simplest programming technique which let the user grasp it very nicely and get the result very easily has made it popular.

Java technology was first developed by a programmer named James Gosling In year 1995 as a project. Java was developed under the umbrella of Sun Microsystems limited which is now a subsidiary of Oracle corporations. Java web Programmer can compile the program with JIT compiler and then the byte code is obtained. These byte codes are platform independent and need different kind of JVM for different machine for example a java program which is written on windows platform is compatible with Linux but what changes is the environment in which this program has to run which is JVM. So Different JVM for different machine let the program run successively which is written on any of those platforms.

Java’s mostly used editions are J2SE java standard edition and J2ME java mobile edition. J2SE is used for development of industrial projects whereas J2ME is used for application development on mobile by use of swing AWT and java applets.

The way java isolates the data from the program that is using the data is called encapsulation and is the most important factor improving java security feature. When the user interacts with java applets the data those are used by application are only accessible in JVM and not to the systems so this way it secures the systems from viruses to be downloaded. Another most important feature is the re usability of code, by the mean of packages in java it is very much easy that a module can be used by many programme just by including the package that consist the module.
