Computer’s 64 Bit – What are the Advantages of More Bits?

Today’s 64-bit computer systems bring us a lot of computer power. Over the past few years, 32-bit systems have become the standard. They have given us great computing capability over the past few years, but it’s clear that the progress made by 64-bit computers makes it a very attractive computer.

Even though these advancements are quite remarkable, there is a lot of confusion about just what this big brother of the 32-bit computer system can and cannot do. No, it isn’t twice as fast. No, it isn’t impossible to find software that runs on it. So, what is the big deal about 64-bit? Furthermore, what does 64-bit mean, anyway? This article will answer these noteworthy questions.

Computer's 64 Bit - What are the Advantages of More Bits?

It All Starts with 1 bit

All computers, of course, work on digital platforms. Every program you open and every other kind of action you take on your computer moves a pile of 0’s and 1’s around. The sensational and remarkable things your computer does for you are possible because of its ability to add series of very large numbers that consist of 0’s and 1’s.

One digit in the realm of computer technology can only be a 0 or a 1. We call this a bit. In our everyday world, digits consist of 10 numbers each. In other words, we use a decimal system. Computers use digits consisting of 2 numbers; a 1 or a 0. This system is what we know as a digital system.

The largest 8 digit number in a decimal system is 99,999,999, or 1 short of 100 million. The largest number yielded by 8 digits in the digital world is 256. 8 digit digital numbers are really popular in computer technology; they are called bytes.

Byte Sized Digits

In one Hertz of an operation, a 32-bit computer is capable of pushing around numbers as large as 4 digits of bytes, or 256 X 256 X 256 X 256. This number is 4,294,967,296. Another way to say this number is 4 Gigabytes or GB. Yes, I know this number looks like it is more than 4GB, but 1GB is equal to 1,073,741,824. Don’t ask, it’s just a digital thing. Anyway, this is why 32-bit systems can address up to 4GB of RAM.

Remember, we’re talking about transferring large numbers in one clock tick. Most of today’s computers make 2 billion or so clock ticks each second. Also note CPU’s, since the Pentium 4 came on the scene, use hyper-threading technology. This allows more than one operation to be performed each clock tick.

A Megaton of Computing Capabilities

As you can see, 32-bit computer systems are capable of performing many calculations very quickly. However, 64-bit systems make them look feeble because in part, they employ dual core processors. So essentially, instead of having one hyper-threading CPU at work, they have two.

Mathematically speaking, the extra 32-bits, or 4 bytes 64-bit gives us, adds 4 more Byte digits to the 4GB number 32-bit is limited by. So theoretically, the amount of … Read More

Want a Faster Computer? Stuff That Really Works for Cheap

We have all sat at an office computer or library computer and experienced a lightening fast response. Or perhaps you had this experience upon firing up a brand new computer. You click on a website and its there in an instant. Once you have had that experience it leaves you wanting more.

If you’re among the many sitting at home wishing they had a speedy computer your not alone. There are a number of little things that add up to a huge difference in overall computer speed. These aspects are not complicated once understood and the good news is it’s not expensive either. Obviously some parts to the equation are more important that others but if you take nothing else from this article understand that your computer can only run as fast as its weakest link.

Want a Faster Computer? Stuff That Really Works for Cheap

The first bit of good news is that you can start replacing these weak links and make some great upgrades to your computer system without spending a mint. Usually refurbished components are not the first viable idea that comes to mind. However with recent leaps in testing technology refurbished computer parts are often just as good if not better than new. This new testing technology is so good that all major manufacturers are now selling refurbished units with great warranties. This has never before been the case.

So what is the weakest link of most computers you’re probably asking yourself? Typically the weakest link is the amount of RAM the computer has. RAM is a form of memory your computer uses that allows multiple functions to occur without it bogging down to a snails pace. As a rule of thumb you need a minimum of 2 gigs of RAM. Ideally you should target 3 or more. The good news is these RAM chips are fairly inexpensive to purchase and have installed. RAM is the one component that is not sold as refurbished as it’s so inexpensive that companies don’t bother to offer it.

The next aspect to focus on is upgrading the processor to at least a dual core processor. This gives the computer an added advantage in being able to crunch more data quicker. Probably this aspect would be the most expensive should you choose to have this replaced. Most just use what’s in their unit at present if you’re short on funds.

Internet connection of course matters but not as much as one would think. As long as you have a high speed internet connection above 5Mbps you have more than enough to get the job done.

Hard drive speed is arguably one aspect which most don’t realize is their weakest link if they have a good processor, RAM levels and internet connection. You might consider a 15,000 rpm hard drive or a refurbished solid state drive. This would speed things up extensively.

The next step in the process is something most never think of. It is the amount of programs they have running in the background. Look in the bottom right … Read More

The Importance From the Strain Gauge

Items for example the strain gauge that measure fatigues in metals play crucial roles in productivity and security. There are many categories of measuring instruments and many extra if the goods inside each and every category are counted. As an example, within the category of strain gauges you’ll find seven sub-categories such as accessories which include cleaning agents and solder terminals. Such merchandise are of vital significance in a globe that is increasingly dependent on high-tech equipment.

The Importance From the Strain Gauge

As the planet revolves a myriad of machines perform smoothly to keep points going. Enormous planes take for the skies in tremendous bursts of energy, and at a distinct level coal powered and nuclear turbines retain the electricity flowing into domestic kitchens. The stresses imposed by heat and movement upon the material elements of all of the machines that power our lives usually do not in themselves bring about break downs but are the causes that should inevitably result in effects. Engineers measure tension in mechanical components making use of several different suggests.

A strain gauge can be a resistance-based sensor made use of by mechanical engineers. Strain does not officially possess a unit of measurement, but for reference purposes, a particular unit of measurement is utilised. Due to the fact the alterations in length are generally really modest, the unit of transform employed is expressed as ten for the power of six, to provide meaningful readings.

You can find several types and configurations of sensors. The metal foil gauge consists of a length of thin metal wire wound about a grid called a matrix. This can be stuck to a metal backing then bonded to the object where measurement is expected. The gauge is aligned together with the line in which tension will occur. As the wire lengthens or compresses, so measurements are taken.

Optical sensors are created of glass, of varying thicknesses. Fibres having a core of 5 micrometers are surrounded by a layer of pure glass using a diameter of 125 micrometers. Distinct reflection points build optical effects. As these gauges are insensitive to electromagnetic fields they’re valuable in explosive atmospheres.

Configurations of gauges can be made to measure different strains that may possibly apply to objects of distinctive sizes and components. One example is the bi-axial configuration can measure along distinctive planes, as within a hole or cutting instrument. Here two unique appliance are aligned at proper angles to a prevalent point as a way to measure along distinct axes.

In addition to measuring mechanically, instruments is often made to measure thermally. The forces applied to continuously welded railway lines occur vertically, longitudinally and laterally. Configurations of unique instruments can present vitally critical data for upkeep crews, and enable to make sure the security of extended distance and high speed trains.

It really is clear that the strain gauge play an important function across the gamut of industrial activities. In mining, agriculture, architecture, building and road creating you will find obvious applications. Much less apparent, but equally critical are … Read More

Video Conferencing Is Within Your Attain

I live in a pretty nice location outdoors of Philadelphia. My children visit the regional public higher college and on their 1st day of classes were issued brand new Apple Macbooks. That’s fairly nice. Not that they use them for actual college function. The majority of the time they’re on Facebook and video-chatting.

Video Conferencing Is Within Your Attain

Video-chatting. My 14-year-old year little ones are undertaking this. My 14-year-old year old consulting business enterprise will not be.

But that is about to modify. Video technology utilised to become also costly for tiny firms like mine. Now, new technologies are hitting the industry and generating it simpler for little fry to play large.

Take Dr. Morgan DeFoort, co-director of your Engines and Power Conversion Laboratory (EECL) at the Department of Mechanical Engineering at Colorado State University. EECL does study on power efficiency and conservation. Lately DeFoort’s group developed, and later helped commercialize, a low-cost stove for distribution throughout the developing globe. That firm now sells some ten,000 stoves a month.

The lab has a full-time staff of eight folks, plus a dozen faculty members, over 40 undergraduate and graduate students, plus a handful of outside partners who work on projects about the world. “We do a lot of computational operate,” says DeFoort. “Recently we worked on ways to improve a stove’s efficiency and modeled the combustion in three dimensions inside the stove. This is not only one thing you can speak about. We required to find out the outcomes, also. It is a really visual thing.”Read All Comments

Engineering-design function is all about collaboration, and that’s exactly where video conferencing comes in handy. Whilst remedial conferencing tools, like Skype, deliver low-quality graphics, high-end video-conferencing systems from the likes of Cisco ( CSCO – news – people today ) and Polycom ( PLCM – news – individuals ) can run to $50,000. That left EECL out of luck. “We have to meet payroll each month,” says DeFoort. “I have a strict budget.”

Option: HP Skyroom, new video-conferencing software aimed at smaller corporations, created by Hewlett-Packard ( HPQ – news – folks ). (The Marks Group does no organization with HP.) In 2008 DeFoort paid $149 per license. Every user also requirements a webcam; those go for about $100 apiece. Set-up takes mere minutes. When configured, cuing up a meeting was just some clicks away. HP SkyRoom also functions with some instant- messaging systems, like Microsoft ( MSFT – news – persons ) Office Communicator. As with Skype, all that information runs over the world wide web. (A single caveat: You need a decent Internet broadband connection, no less than 400 Kbps, to make it hum.)

DeFoort is hopped up on Skyroom’s excellent. The information streams hardly ever get interrupted, along with the graphics are fantastic, with 1900 x 1080 pixels-per-line resolution or greater. (A normal computer system screen delivers 1024 x 768.) “The free software program I’ve tried, like Skype, does not give this type of resolution,” says DeFoort. “It was worth the couple of hundred bucks … Read More

Emerging Technologies: Processor Boundaries Breached

When we examine the micro processors which might be applied on laptops and smart phones to the insanely fast core processors of desktops, the desktops would usually sweep the competitors. Aside from becoming relatively more rapidly compared to micro processors, the core processors can manage multi tasking and heavily loaded applications that we run on our desktops.

But there is certainly an emerging technology that will give a promising outcome of nearing the gap between micro and core processors. Inside a report of communications breakthrough, a team of scientists in the University of Pittsburgh claimed to a thriving generation of a brand new frequency comb, which entails dividing a single colour of light into a series of evenly spaced spectral lines for a selection of uses, that spans greater than 100 terahertz (THz, or 1 trillion cycles per second) bandwidth (zdnet).

Terahertz has never ever been reached and applied to any processors that we’ve out there, and if this can be applied to future laptops and smart phones the new technology could make them 1000x more rapidly. This could undoubtedly total the mobile solutions that we want to have on our devices.

Emerging technologies: introducing the new 3D printer

3D scans can now be printed inside a matter of seconds making use of a new approach, generally known as two photon lithography, which was created by researchers at the Vienna University of Technologies.

Professor Jargen Stampfl, a professor in the Institute of Supplies Science and Technology in the TU Vienna mentioned the technique, until now, made use of to be very slow. With this improvement, the scientists that spear headed the research are now developing the two photon lithography to be utilized for healthcare applications. As of the moment they may be also producing improvements to utilize the 3D printer and its technologies to be applied in the creation of tailor made elements for nano technology or biomedical technology.

The nano printer is employing a liquid resin that is definitely place on the correct spots by the usage of a focused laser beam. Together with the enable of movable mirrors, the point from the laser beam is guided as it goes via the resin leaving a trail of a strong polymer. The finish outcome can be a tiny sculpture measuring just about numerous micrometers in length. But it is quite detailed, and having a printing speed of a couple of meters in just five seconds it’s unquestionably an improvement by leaps and bounds.… Read More
