History Of Computers

The history of computing hardware is the record of the constant drive to make computer hardware faster, cheaper, and store more data.Before the development of the general-purpose computer, most calculations were done by humans. Tools to help humans calculate are generally called calculators. Calculators continue to develop, but computers add the critical element of conditional response, allowing automation of both numerical calculation and in general, automation of many symbol-manipulation tasks. Computer has undergone profound changes every decade since the 1940s.Computing hardware has become a platform for uses other than computation, such as automation, communication, control, entertainment, and education. Each field in turn has imposed its own requirements on the hardware, which has evolved in response to those requirements.Aside from written numerals, the first aids to computation were purely mechanical devices that required the operator to set up the initial values of an elementary arithmetic operation, then propel the device through manual manipulations to obtain the result. An example would be a slide rule where numbers are represented by points on a logarithmic scale and computation is performed by setting a cursor and aligning sliding scales. Numbers could be represented in a continuous "analog" form, where a length or other physical property was proportional to the number. Or, numbers could be represented in the form of digits, automatically manipulated by a mechanism. Although this approach required more complex mechanisms, it made for greater precision of results.Both analog and digital mechanical techniques to be developed, producing many practical computing machines. Electrical methods rapidly improved the speed and precision of calculating machines, at first by motive power for mechanical calculating devices, and later directly as the medium for representation of numbers. Numbers could be represented by voltages or currents and manipulated by linear electronic amplifiers. Or, numbers could be represented as discrete binary or decimal digits, and electrically-controlled switches and combinatorial circuits could perform mathematical operations.The invention of electronic amplifiers made calculating machines much faster than mechanical or electromechanical predecessors. Vacuum tube amplifiers gave way to discrete transistors, and then rapidly to monolithic integrated circuits. By defeating the Tyranny of numbers, integrated circuits made high-speed and low-cost digital computers a widespread commodity.This article covers major developments in the history of computing hardware, and attempts to put them in context. For a detailed time line of events, see the computing time line article. The history of computing article treats methods intended for pen and paper, with or without the aid of tables. Since all computers rely on digital storage, and tend to be limited by the size and speed of memory, the history of computer data. 

The Desktop Computer Isn't Dead Yet

According to news articles in the past year or two, the desktop computer is beginning to cry "I don't want to go on the cart." According to this article, the arrival of real tablet PCs is going to take a slice of the computer market, and it won't be coming from netbook or laptop sales.

I won't deny that laptops are everywhere these days, and getting more powerful all the time. Currently, I use a laptop as my main computer, and have a 10-year-old desktop kicking around used to play YouTube videos and such on my TV. I, for one, plan to buy a desktop computer as my next major computer purchase, for several reasons.

Firstly, my laptop hardware went obsolete REALLY fast. I bought it in July 2007, and by the fall there were far more powerful models out for the same price. I bought a model with a decent-enough video card in hopes of playing a few games, but even games of several years earlier than 2007 had to be run with minimal video settings. As far as 2010 games go, the situation is hopeless.

Secondly, I dislike very much that for my laptop's processor to run at full advertised speeds, the bottom of the computer gets hot enough to cook pizza pops on. If I hadn't bought the 12-cell battery that lifts the bottom of the computer off the desk, providing extra ventilation, the computer would be hot enough to cook two pizza pops on. It's possible that newer laptops are better now and don't run as hot, but I've always found myself running in power saver mode at 600 MHz just so I didn't scald my lap.

Thirdly, one of the main arguments against desktop computers is that they are chained to your desk. While it's nice that laptops have batteries and can go anywhere, they still need to spend some amount of time chained to a wall outlet every so often. Until wireless power is brought to the consumer market, laptops will still partially have the same chained problem as desktops. After a few years, your laptop battery goes and you have to stay chained to the wall all the time anyway.

Desktop computers have much more longevity than laptops for several reasons, meaning that they're more worth the money you spend on them in the long term. First and foremost, desktops are super upgradeable if you buy a system with future upgrades in mind. You can always pop in more RAM, another hard drive, another video card, etc. Laptops are almost always not so. Also, the hard drive in a desktop will last much, much longer than that of a laptop, because it remains stationary all the time. Laptops bounce around all over the place, and usually the hard drive will give out in a few years' time at most. My current 10-year-old desktop still has its original hard drive running fine. When your laptop eventually does need repair, one needs to either send it away to a manufacturer for weeks, or attempt to dismantle the entire computer, just to tinker with whatever is broken. When a desktop computer is opened up, everything is easily accessible and within reach.

It used to be that you could make a valid argument against desktops and their space requirements. You need room for that giant CRT monitor, and someplace to put your tower. These days, you can buy compact desktops that are about the size of a laptop standing on its side, or even smaller if you look at the Home Theater PC market. LCD monitors are the standard these days, so they don't require much space either.

I can't speak for the rest of the computer user world, but when I need to sit down and focus on work on the computer, I work more productively if I'm sitting at a desk. If I'm sitting at a desk, I enjoy having a big screen to spread out all my windows on, and a mouse and keyboard. I could use all these accessories with a laptop, but it seems more practical to me to have a dedicated desktop hooked up, rather than plugging and unplugging from my comparatively underpowered laptop all the time. I can especially see this situation if I ever found a job doing computer work from home, as I imagine is the case for a significant portion of the working population in the computer industry.

In the past year or two I've seen home servers come out on the market for the average computer user. Regular users are beginning to realize the importance of file backup and the convenience of central media servers. Combine this market with the home theater market, and you have one desktop-dominated market area. Laptops just don't make sense to be run as always-on servers.

Desktops can clearly offer more performance power than laptops if you are willing to pay for it, and it's not just hardcore gamers that need the power anymore. Users of CAD software, graphical design software, video editing and encoding software, and virtualization software all need a large amount of RAM, processing power, and storage space. Even software developers would enjoy faster compile times for development projects, even if it means less time to use as a valid slacking-off excuse.

In short, if desktops are losing share of the PC market, it will stop losing and eventually stabilize. The desktop computer is not going away any time soon.

The Benefits Of Promotional Merchandise

Near the end of the business presentation you hope impressed board members, thunder cracks loudly and rain begins to fall in steady force. The corporate heads suddenly look to be a very somber group indeed. Pull out your printed promotional umbrellas and pass them around. Your likeability meter has just moved to the highest measuring point. This benefits you with a better chance of securing business dealings with the corporate leaders who hold the power of deciding who is awarded with business contracts.

Promotional merchandise holds many other benefits which make them a worthwhile consideration. Those printed, promotional umbrellas you just gave away will keep your business in the forefront of board members minds, even if you are not the only hopeful to make a presentation to them today.

As business owners we are always in search of ways to advertise effectively while keeping costs to a minimum to maximize our overall profits.

Advertising Strategy - Tips for Using Custom Promotional Products

Promoting a brand or company does not always have to break your bank. By giving away cheap promotional products or items, your brand or company can still stand out without having to shell out much as you would with TV or radio ads. However, with so many promotional products available on the market these days, choosing the perfect item to give away can be a really daunting task. Here are some useful tips on how to find the best promotional products to give away to increase your brand's visibility.

Know Your Target Market

The most important tip to start an effective campaign is to know who your target people are. One of the big mistakes of some companies is misunderstanding their target market. Many companies lose track of their main target audience or tend to reach others outside of their current market. Thus, their promotional products become useless.
By understanding who your target people are, you will have an idea on what type of products that will likely grab their attention, what type of items they need and they will find useful. Remember that while there are so many marketing products you can choose from, not all of them will work on your target market.

Choose Quality over Quantity

When deciding on a promotional item to use for your marketing campaign, the rule of thumb is to choose quality over quantity. Some companies make the mistake of choosing quantity over quality in the hope of reaching more people. But this can easily ruin your marketing campaign as poor quality products easily get damaged or broken, thus allowing your advertisement to only last for a short period of time. In addition, while giving cheap quality products will initially save you money, people will associate your brand or company with the quality of your promotional item as well. Because they easily get damaged and your ad won't last long, then you will have to spend money for another campaign again.
Good news is that whether you are looking to give a mug, t-shirt, umbrella or pen, there is a wide range of affordable quality items to choose from these days

Useful Promotional Products

Choose promotional products that your target market will use. Many companies make the mistake of just using any product to give away, not considering its use to their target market. The end result is that the items just get forgotten, kept inside the closet, or worse, thrown away.
Thus, if your target people are students or young professionals, give them something that they see and use everyday. For this group of people, things like pen and other office items are far more effective than jackets, drink coolers or towels.

Budget

Of course, your pocket is always one of the things to consider. If you have a tight budget, then choose items that are affordable, but never compromise quality still. Instead of choosing bags, t-shirts or jackets, choose items that are more affordable but are still useful to your target market. These may include lanyards, pens, and koozies.

Promoting your company does not always have to come with a huge cost, and does not always need to be done through TV or radio. Giving custom promotional products serve the same purpose at lesser cost! Start promoting your company now through unique and useful giveaways that your target market will love!

The Benefits of Yoga

Yoga is a healing system of theory and practice. It is a combination of breathing exercises (pranayama), physical postures (asana), deep relaxation (yoga nidra) and meditation (dyana), practiced for more than 5,000 years.

While Yoga evolved as a religious practice in Hinduism, in the Western world has grown as a form of purely physiological, psychological, mental and spiritual practice. Most of the yoga practices in the western yoga have little or nothing to do with Hinduism, but are simply a way of keeping all levels of the human being, fit and healthy and this is only a part of the broad view of yoga. Through the practice of yoga, we become aware of the interconnection between our spiritual, mental, emotional and physical levels. Gradually this awareness leads us to an understanding of the more subtle areas of our existence.

Yoga practice prevents specific diseases and maladies by keeping the energy meridians (nadis) open and life energy (prana) flowing. Yoga is considered a mind-body intervention that is used to reduce the health effects of generalized stress.

Laboratory tests have proved the yogi's increased abilities of consciously controlling autonomic or involuntary functions, such as temperature, heartbeat and blood pressure.

Yoga acts both as a curative and preventive therapy. According to medical scientists, yoga therapy is successful because of the balance created in the nervous and endocrine systems which directly influences all the other systems and organs of the body.

Regular practice of poses (asanas), breathing exercises (pranayama), deep relaxation (yoga nidra) and meditation, can help such diverse ailments such as: acidity , allergies, Alzheimer disease, anaemia, anger, anxiety, arthritis, asthma, back pain, bronchitis, cancer, carpal tunnel syndrome, chronic fatigue, colitis, common cold, constipation, depression, diabetes, epilepsy, eye problems, facial wrinkles, gastro-intestinal disorders, headaches, heartburn, haemorrhoids, hepatitis, high blood pressure, hypertension, immune-deficiency, impotence, menopause, menstrual cramps, migraines, multiple sclerosis, muscular dystrophy, nervous tension, obesity, osteoporosis, prostate, enlargement, sciatica, skin problems, sleep apnoea, slipped disk, sterility, stiffness, stress, insomnia, intoxication, thyroid problems, kidney stones, stuttering and stammering, urinary tract disorders for women, vaginal infections and many more.
