Touch Screen Computers

Tags : 

Touch screen computers are the type of computers that have screens that can be touched to input information. Below the surface of their screens are a series of touch pad receptors that receive input every time the screen is touched. Touch screen technology like this first began to be developed in the 1970’s and it has gradually been advanced over time.

Microsoft Corporation first began to develop software for touch screen computers when they released their Surface operating system. This operating system was used primarily on table top applications and mostly in the commercial environment. Readers may recall seeing touch screen computers in use over the past decade in major restaurant chains when a receipt is being printed or when orders are being sent through to the kitchen. In recent years, Apple has propelled the advancement of touch screen technology by the development of the iPhone. The iPhone primarily receives input through its touch screen; no keyboard is required and neither is a stylus. Since the popularity of the iPhone, other mobile phone makers have begun to develop and make use of touch screen technology and it is now becoming more commonplace.

Using touch screen computers is in many ways is a lot easier than using a keyboard to input data and to generate commands. The keyboard is the traditional way of operating a computer and although it offers almost unhindered control over computers it also creates more bulk. Therefore most devices with keyboards tend to be bigger. Today’s consumer, however, is looking for smaller, slimmer devices that can be carried around with them, and that can be operated quickly with the most ease.

Fortunately, touch screen technology is extremely quick and it reduces the amount of equipment that computer users have to contend with. In the case of mobile computers, there is less to carry around. For manufacturers there is less to add to their devices. Less moving parts means less bulk and less to break. Due to the convenience of touch screen technology, most manufacturers of mobile devices are moving in the direction of touch screen technology only. The Apple iPhone is an example of this and definitely the forerunner of this trend.

A more recent development that will increase the popularity of touch screen computers is Microsoft’s Windows 7. The development of the Windows 7 operating system will most likely lead to more widespread use of touch screen technology. This is because Windows 7 has been developed with touch screen computers in mind. In fact, it is the first Windows operating system that Microsoft has focused attention on touch screen technology. The expected result is that many new touch screen devices will appear on the market with Windows 7 as their operating system of choice.


iPhone vs Android

Tags : 

The iPhone and the G1 phone (with Android operating system) are two mobile phones that have grown rapidly in popularity as well as in rivalry over recent years. The phones are similar to one another in that they push the envelope of mobile and touch screen technology. Both phones offer users not only the ability to make phone calls on the go, but also to make use of a host of useful applications and other features on their mobile phones.

The iPhone and its operating system has been available for a few years now and was developed and launched by Apple, Inc. The Android operating system on the other hand was developed by Google. Google then worked closely with High Tech Computer Corporation (HTCC) to develop the actual G1 phone and it’s hardware.

When it comes to priorities in development, mobile technology continues to be given a very high priority. This is simply because people throughout the world continue to rely more and more heavily on mobile technology. Mobile phones are not just used to make phone calls but increasingly they are being used to connect to the Internet on the go. Whether people are using this to find maps and directions, or to update their status on a social networking web site, mobile phone makers are obligated to provide this technology.

The main feature of both the Android operating system (OS) and the iPhone is the ability to surf the Internet. Both of these phones come with a wide screen and with WIFI capabilities, giving users the option to browse the Internet at leisure. Browsing speeds are reasonable and provide people with great convenience.

The iPhone is highly popular. When it first came out, it offered features that were considered revolutionary for the mobile phone in so many ways. Other phone makers are beginning to catch up but generally speaking they are not there yet. The iPhone is navigated primarily through touch screen technology. Users dial numbers through touching the screen, they send text messages and operate the various applications that the iPhone contains all through screen touch.

From reviewing both the G1 and the iPhone, I would say that the Google G1 does have some advantages over the iPhone however it does not fully surpass the iPhone or its technology. Definitely the keyboard that comes with the G1 is an advantage. Although the iPhone’s touch screen keyboard is fun and new, people are still quite conditioned to using a keyboard when operating computers and I believe that using a keyboard will still be their preference over touch screen technology for some time to come.

The G1 gives its owners access to the battery so that they are free to swap a fresh battery in at will. Although this seems like a fairly basic feature it is not the case with the Apple iPhone. iPhone users have to send their phones to Apple to have their phones replaced and therefore swapping batteries in and out while on the go is not an option. At present, the Android cannot compete with the iPhone’s media player. The iPhone has simply taken the mobile media player to another level and it will take the Android some time to compete with it. Lastly, the design of the iPhone is much slimmer than that of the Android. Slim is always more ideal than bulky. Users want devices that require the least amount of space in a pocket or hand bag.


Choosing a Digital Camera

Tags : 

Digital cameras have changed the way that we take photos! The obvious convenience of taking photos with a digital camera is that you can view the photo immediately, and if there is any problem with it, you can delete it and re-take it instantly. No more frowns or bunny ears going down on record in your family history!

What are the things that you look out for when buying a camera? I can only assume that you will want to buy the best camera possible for the amount of money you have to spend. How do you know which is the best camera to buy? There are some buzz words that you will hear often when you are shopping for a digital camera: Megapixels, resolution, memory, RAM… what do they all mean?

The first important thing to know when buying a camera is its resolution. Camera resolution gets better and better with each passing year. It is not a stagnant technology. Still, find out what should be standard resolution at the time that you buy your camera. Resolution is measured by megapixels. Your aim is to buy the camera with the best resolution for your budget.

Another characteristic that you should look for in a digital camera is the lens. Try to buy a camera with a glass lens, as opposed to a plastic lens. This will have a huge impact on the quality of the images it produces.

Memory is another important thing to consider for your digital camera. Most digital cameras allow for an unlimited amount of storage memory to be used through memory cards. Never buy a camera that only has built-in memory and does not allow you to extend storage through memory cards as this will be a huge limitation.

One of the features that you are likely to experiment with the most when taking digital images is zoom. Zoom technology is another one that gets better with time. Still, ask around at the time that you are buying to find out what is a reasonable zoom capacity to expect.

The best place to research a digital camera before you invest in one is on the Internet as you can read reviews, find out the technical specifications and compare prices.

Lastly, I always recommend that you ask around when you are going to make any kind of purchase. What are other people saying about the camera you want to buy? What are they saying about the cameras they own? If the camera you want to buy is a dud and someone you know has bought it, they can save you a lot of frustration and wasted money. If you want to be doubly sure, check what other consumers are saying about the camera you want. Check the reviews on web sites. This is a place where you can get the real deal on all types of consumer products.


What to Look for When Buying a Printer for your PC

Tags : 

Computer and Internet technology provide us with the prospect of very soon conducting work and business using electronic and digital documents only; in essence, a paperless environment. However, there will always be a need to print documents every once in a while.

The cost of a printer is usually very low. Printer manufacturers know that they will make enough of a profit on ink cartridges to risk taking a small loss selling the printer. Therefore, many consumers find themselves in the position where they have a fantastic printer but over time, can not afford to buy ink for it.

A printer can usually only be used with unique ink cartridges made specifically by the manufacturer for that printer. This is something to bear in mind when you are making a decision about which printer to buy. Before committing to a specific printer, find out how much it will cost you to keep the printer supplied with ink cartridges.

Even though printers are sold cheaply, it is still important to make sure that you are buying a quality printer. You don’t want to have to shop for a new printer in a few months no matter how little you paid for it. Find out what people are saying about the printer you have your eye on. Review web sites are a great place to hear directly from other consumers.

Whether you are a student and will use your printer at home or if you are buying a printer for business purposes, you will probably want a printer with a few extra features. A variety of good features come packaged with today’s printers. A scanner, fax and copier are common built-in add-ons and ones that are recommended for home office use.

Printers come quite cheaply these days. If you take the time to do a little bit of research before buying, you can prevent yourself overspending on ink and from suffering with a printer that functions as cheaply as the price you paid for it.


What Kind of Computer is Good for Gaming?

Tags : 

I am not sure whether you have any gamers in your family or among your close group of friends. Gamers are unique. They spend huge amounts of time trying to reach the highest levels of the games they play. Their free-time is booked up and spent on gaming. Those that don’t play computer games can only look and wonder why? What is the fascination?

Gamers love what they do and they really put their computers through a pounding. They run their computers to the max because the games they play usually use high resolution graphics, sound effects and lots of memory. When it comes to buying a computer for gaming, a lot of gamers prefer to either build their own computer or have one built specifically for them. Building your own computer is the least expensive way of doing things and it is the most customisable because you can make your computer into whatever you want it to be.

Your average computer is not made with gaming in mind but rather for the average, every day computer user. You can use a regular computer for gaming however you probably would not be satisfied for long because your games would most likely max out your computer system resources. To use a computer for gaming you may need some enhanced components. Definitely you will need to invest in an above average graphics card. Your graphics card will affect the way that images, colours and the scenes in your game will display on the monitor.

The main components that your computer will need for gaming are: an excellent graphics card, a good sound card, speakers (preferably with a sub woofer) and also a good monitor. If you want to upgrade a computer that you currently own, you will at least want to turn things up a notch with an upgraded sound card and graphics card. You can easily buy and add a new graphics and sound card to the computer set up that you already have.

If you are one of those people that doesn’t like to get into the nitty-gritty technical stuff, you probably prefer to be pointed to a particular computer brand rather than have to understand computer specifications and memory requirements. If this is you, then be on the lookout for Alienware computers. Alienware is one of the most popular brands for gaming. They do great desktops and laptop computers. Gaming computers cost considerably more than your every day computer. Still, if you are heavily into gaming, the cost will be well worth the hours of entertainment you will get from gaming on a computer you love.

What's the difference between LCD and Plasma

Tags : 

Flat screen TVs give a modern, fashionable look to your home. Although flat screen TVs give high definition and crystal clear pictures, not all flat screens are equal! Generally, flat screen TVs come in two different varieties: LCDs and Plasmas. When buying a flat screen TV, you will choose between a plasma or an LCD television.

Plasma TVs take advantage of a fairly old technology but in a new way. They give a crystal clear picture that is high definition and they do it through tiny tubes that are filled with neon and xenon gases. This new use of neon gives plasma TVs their amazing picture clarity.

Liquid Crystal Display (LCD) uses an older pixel technology. LCD TVs create their clear picture by placing pixels in front of a reflector or a source of light. LCD technology is not only used in flat screens, its popular in portable devices because it only needs a small amount of battery power.

When it comes to buying a flat screen TV, both plasma and LCD technologies have their pros and cons. Which one you choose depends on your own situation and how you anticipate using your television. LCD technology has some screen size limitations. Plasma technology allows for much larger screens than LCDs. So, if size is a factor for you, a plasma TV would be the way to go.

You can potentially have a very flat screen with both LCD and plasma technology, especially in comparison to traditional televisions. However an LCD TV can go the flattest. LCD TVs can be as thin as 2 inches, they tend to weigh much less than plasma televisions and require only about half the electricity of a plasma.

Plasma TVs have delicate, vulnerable screens. They can easily sustain damage and are expensive and, at times, impossible to repair. LCD televisions have much tougher screens which have a longer lifespan overall.

One of the most significant differences between a plasma TV and an LCD is their response time during fast action sequences. LCD screens have more of a process to go through to create an image onscreen. Therefore, they can have a slight blur during fast, action scenes. On the other hand, LCDs offer more clarity on still pictures.

Quick tip: If you see an investment “opportunity” on Facebook, run a mile. Maybe two or more, because they’re ALL scams, and, sadly enough they’re
