How To Wisely Buy A New Computer

How To Wisely Buy A New Computer


We are now into 2012, and your old computer just quit. Do you fix it or buy a new computer? If the computer is 5 years old or older, then probably buying a new computer is the better strategy. Many computers manufactured 5 to 9 years ago have hardware components that fail mandating replacement of the computer. Please read on to understand how to buy the best computer for your needs.

The first decisions to make in buying a new computer are very basic. By answering these questions you determine your basic purchase strategy:

1. Please ask yourself "How much can I spend?" The computer prices range from $200 to $400, $450 to $800, and $900 and up.

2. Next determine the computer type (or style) that works best for you. The types of computers are desktop, laptop, and tablet. These types of computers differ in their size, portability, and functionality. Desktop computers are the least portable. They are good for using multiple displays and heavy workloads. Laptops vary in size and portability. The big ones have 17-inch display making them luggable for occasional trips. Big laptops have most of the capabilities of a desktop but the computing horsepower is lower than a desktop in order to conserve laptop battery power. Similarly, the display is smaller with lower resolution than displays used with desktop computers. Tablet computers are the most portable. They can do a lot, but with a much smaller display. The tablets are a powerful, portable information tool that is one step above a smartphone.

3. Finally, the timeless question is: Do I buy an Apple or another computer? The other computer main selections are Windows 7 operating system or Android operating system computers. There are also Linux computers. Linux is free General Public License software operating system. Linux computers are equivalent for everyday users to Windows and Apple computers. The single difference between Linux and Windows is that with a Linux computer you only pay for the computer hardware which is a huge savings over Apple and Windows computers.

The market for Apple computers is tightly controlled. This means that Apple computers work very well with few problems. They are seldom attacked by malicious software. Everything an enthusiastic Apple owner says about their Apple is true. They are also beautiful looking computers. The down side is that they are expensive. When an Apple does malfunction, you have a big problem. If the Apple computer is under warranty, then you schedule a visit to the Apple store and wait in line to get it fixed. Also, you pay a lot for the repair.

In contrast Windows 7 computers are like the Wild West. In the Wild West anything can and does happen. There are many competing hardware and software products for Windows 7 computers. Windows 7 computers are the most malware, spyware, and virus attacked computers. Because there are more Windows computers sold than any other computers, Windows computers are the biggest target to attack. Apple computers also get viruses, but much less often than Windows computers. Windows computers can be cheap computers but they are not cheaper than Linux computers.

4. The final question is: What computer manufacturer do you like? Each manufacturer has its approach to selling computers. My preference is manufacturers that do not add fancy frills beyond the basics that come with Windows or the computer operating system. Most of the frills try to sell you something, provide functions that a redundant with the operating system, they occupy screen space getting in the way of what you are doing, and they overload and slow down the computer. For example, HP computers are like Big MACs, they taste great but come with a lot of software fat. Lenovo computers are like a bank vault. They secure your data but are miserable to fix because of the security. It seems that all computers come with an annoying "dock" or application launcher. It takes up a lot of screen space and really adds little beyond what Windows itself provides. It is always cheaper to purchase a package than to build a custom computer. Purchasing custom computer parts is always more expensive than buying a packaged system from a manufacturer because the manufacturers purchase computer components in such high volume.

Once your basic strategy is determined, then it is time to find a computer. The approach here is to use the Internet to perform the initial shopping and then go to the store to make the final decision and purchase. Please go to the web site of a computer retailer near you such as Best Buy or Staples. Search their site based on the type (or style) of computer that works best for you. The site should produce a list of computers from which to choose. Sort them by "Best Selling" and check the "Customer Reviews". Please determine how the price compares to your budget. Most retail store sites permit comparing the features of three computers side by side. Carefully select three computers for comparison.

This approach was used to compare from one retailer three desktop computers moderately priced. They ranged from $429.99 to $699.99. The $429.99 computer used a 3.3 GHz Intel i3 CPU chip, had 6 GB RAM, and a 1 TB disk drive. The 549.99 computer used an AMD 2.4 GHz CPU chip, had 8 GB RAM, and had a slower 5,400 rpm 1.5 TB drive. The $699.99 computer used an Intel 3.0GHz i5 CPU chip, had 6 GB RAM and a 7,200 rpm 1 TB drive. The differences between these systems are not likely to make the most expensive system perform that noticeably better to a user than the least expensive system. As long as the hardware features are generally in the same range the performance seems to be the same for each computer.

All systems used the latest DDR3 RAM. The computer with 8 GB of RAM may perform better than those computers with 6 GB of RAM. One thing is certain; all these computers would be decidedly faster than a Windows XP system with 2 GB of RAM. While special performance test programs can measure the performance difference between a 2.4 GHz AMD CPU chip computer and a 3.3 GHz Intel i5 CPU chip computer, people barely notice the difference. What people do notice is that AMD chip computers usually are cheaper by $100 or more than Intel CPU chip computers.

The Windows Performance Index is a measure of the combined performance of all the components of a Windows Vista or a Windows 7 computer. The Windows Performance Index is a single number that varies between 1 and 7.9. Low end systems have Windows Performance Index numbers in the 3.4 to 4.5 range. A computer with a 3.4 score perform the same as a computer with a 4.5 score to a human. To see a performance difference the Windows Performance Index would need to go from a 4.5 to a 7.5.

The Windows Performance Index is not mentioned in any advertising to my knowledge. It is found on Windows 7 computers by opening START, clicking the right mouse button on the COMPUTER menu selection and then selecting PROPERTIES from the drop down menu that appears. To see Windows Performance Index you would need to have a store sales person fire up the computer and help you view it.

Apple computers usually have hardware operates at slower speeds and has smaller capacities than Windows computers. The Apple computers perform as well as or better than their Windows competitors because they use a different and tightly controlled operating system. The software interaction with the hardware makes up for the slower Apple hardware.

The final comparison area is in the display. Monitors today use Light Emitting Diode (LED) backlighting. The LEDs use little power and should last seemingly forever. Monitor physical size contributes to visibility. A character on a 14-inch monitor is smaller than the same character on a 24-inch monitor. The bigger monitor images are more easily viewed. Monitors resolution is expressed in horizontal by vertical dots or pixels. Typically they are something like 1600 by 900 dots. Monitors with a larger number of dots of vertical resolution have a better display. Often monitors will be advertised as 1080p. The 1080p resolution is 1080 dots of vertical resolution with each line refreshed on each scan cycle. On a 1600 by 1200 monitor you can see a full 8.5 by 11 inch page when it is viewed at full size or 100% zoom. Monitors with 900 dots vertical resolution often cut off the bottom of the page when it is viewed at full size.

The final bit of wisdom to consider in purchasing a new computer is not to purchase the most expensive computer. Here is why. A client asked me to get him a computer. At the Dell web site I configured a computer with what seemed to be modest features. This computer cost $3,000. At Costco they offered a computer package that had somewhat lower performance features for under $1,000. If the client purchased a new $1,000 computer every year for three years, at the end of three years he would have better computer than if he purchased the $3,000 Dell computer. Only purchase the most expensive computer if you must absolutely have the features and performance it provides. Otherwise stay with more moderately priced computers and purchase them more often. Buying two $400 computers is better than going for a single $800 computer in the long run.

Choosing the Best Desktop Computer For You


Like a lot of people in the world today, you probably have a specific budget in mind when you buy a desktop computer. You may wonder, though, how to pick out the computer. What size and shape you need and with all the new technology out there, you may be unsure what to get. We are here to help you with this most difficult decision. Read on for some great insight into what to look for when purchasing a great desktop computer.

There are four different types of a PC user. Read below to find out which one you are. This will help you choose the best computer for you and your family.

General purpose user: a general purpose use desktop computer is perfect for those who like to make pictures, edit pictures, play games and surf the net. Depending on what you need a general purpose computer can range in price from $500 to $1500.

Power User: a power user computer is a computer that can be used to make and edit movies and videos. These types of computers also allow you to make digital designs and play mega games. With these computers you will typically need 2 or more hard drives and a great graphics card. These computers typically run higher in price due to the power behind the computer and the different running systems that it will include. A power user computer can range in price from $2500 to $3500 depending on what you will need to perform the types of work that you want to do on this computer.

Home Theater Enthusiast: Do you love movies and television? Why not get a computer that can handle all of your home theater needs? This type of computer is great for people who love to watch movies and television. Windows Media Center is on all of the windows programs including the new Windows 7. When considering this type of computer always keep in mind what type of media you will be playing. This will help you to decide the video card and how much memory and output you will need. You can also find surround sound for your home theater computer, which will make your home theater even more special. When purchasing this computer make sure that is has the proper DVD drive or if you desire you can get a computer with a blue ray player allowing you the maximum high definition display. This type computer can range in price from $500 to $1500 depending on what you need included with the great entertainment model computer.

Home Office Worker: this is a great computer for those who work from home. With this type of computer you do not need the massive graphics power as other computers unless you design graphics for your home office work and then you would want a computer with a higher graphics count. You will want a system with a dual power core so that you can multitask and get the work done that you need done. Windows has a great operating system in Windows 7 that is great for being able to multitask. The newest feature on Windows 7 allows you to have different windows open at one time and you are also allowed to have them up side by side. This will save you time and you will not have to worry about your computer crashing. Mac also has a great operating system for home office as well. A home computer can run in price from $500 to $2,000 depending on what you need and how you plan on using it.

There are many different features to consider when wanting to purchase any of the before mentioned computers. The main great features that you will want to consider are:

* Processor: The two most common type of processor is AMD Athlon 64 X2, or Intel Core 2 Duo processor. You will want a Duo processor if you will be doing a lot of work or something that calls for a high speed processor such as burning or making videos and DVD's. A processor is at the most basic form the brains of your computer. The faster your processor is the better performance you will receive out of your computer.

* Memory: The memory in a desktop computer can vary due to the upcoming technology. Depending on what you need you can find a desktop that has 1G to 4G's of memory. Memory is changing due to different technology every day. When considering the memory take into consideration what you will be using your computer for. The more pictures and videos you need to make will increase the gigabyte count. Having the maximum amount of memory allows you to have plenty of room for all those important things that you want to install on your computer.

* Hard Drive: Depending on what you will need to store on your computer, you can find the perfect hard drive. A hard drive for this type of desktop can range from 250 G to 500 G. When choosing the hard drive, keep in mind what kind of programs you want to install. If you are wanting to install games or photo editing software, it would be best to have a higher gigabyte count. This allows you to have plenty of space for these programs as well as other programs including music and videos.

* Running system: When choosing your computer you will want to pick out a operating system that will work great for you. You can choose Windows or Mac. Both are very reliable brands and will give you a great computer experience. The latest version of Windows is Windows 7 and the latest version of Mac is the Apple OS X Leopard. The feedback on both of these programs are great. You can also ask friends and family that have these running systems how they feel about them and this will help you to pick out the perfect running system for you.

* Video Card: the video card helps to control different graphics and video. The most typical video card is 128 mb and comes from NVIDIA and ATI. With ever changing technology the video card will increase in megabyte size and quality. Most computers come with this feature already installed for quality graphics.

* Keyboard: Your computer would be basically useless without a keyboard. There are several different choices of keyboard. If you have trouble with your wrists, you can find a keyboard that is ergonomic and has a wrist wrest built into the keyboard. If you do not want the headache of wires all over the place, you can purchase a wireless keyboard. A wireless keyboard gives you access to your computer without the clutter of wire.

* Mouse: The mouse is a key component in the running of your desktop computer. The mouse helps you click on links and scroll down throughout pages. A wireless mouse is the latest invention. You can move your mouse around without the constraint of wire. This is a great way to perform your task. A computer can function without a mouse but it would be very difficult to use.

* Monitor: The monitor is the most important part of the computer besides the hard drive. The monitor allows you to see images and what is on your computer. You can find average size monitors, wide screened monitors and flat screened monitors. You can even find HD monitors that deliver a even clearer pictures. The size of the monitor depends on what size you need for what you will be doing with your desktop computer. With larger screens you will have the ability to watch many different movies in television size.

* Web Camera: a web camera can be hooked up to your computer allowing you to take images and videos and save them directly to your computer. You can also video chat with people online using it with Yahoo, Skype or even Facebook. It is a great way to stay in contact with friends and family.

The Evolution of Technology - The History of Computers

The Evolution of Technology - The History of Computers


While computers are now an important part of the lives of human beings, there was a time where computers did not exist. Knowing the history of computers and how much progression has been made can help you understand just how complicated and innovative the creation of computers really is.

Unlike most devices, the computer is one of the few inventions that does not have one specific inventor. Throughout the development of the computer, many people have added their creations to the list required to make a computer work. Some of the inventions have been different types of computers, and some of them were parts required to allow computers to be developed further.

The Beginning

Perhaps the most significant date in the history of computers is the year 1936. It was in this year that the first "computer" was developed. It was created by Konrad Zuse and dubbed the Z1 Computer. This computer stands as the first as it was the first system to be fully programmable. There were devices prior to this, but none had the computing power that sets it apart from other electronics.

It wasn't until 1942 that any business saw profit and opportunity in computers. This first company was called ABC computers, owned and operated by John Atanasoff and Clifford Berry. Two years later, the Harvard Mark I computer was developed, furthering the science of computing.

Over the course of the next few years, inventors all over the world began to search more into the study of computers, and how to improve upon them. Those next ten years say the introduction of the transistor, which would become a vital part of the inner workings of the computer, the ENIAC 1 computer, as well as many other types of systems. The ENIAC 1 is perhaps one of the most interesting, as it required 20,000 vacuum tubes to operate. It was a massive machine, and started the revolution to build smaller and faster computers.

The age of computers was forever altered by the introduction of International Business Machines, or IBM, into the computing industry in 1953. This company, over the course of computer history, has been a major player in the development of new systems and servers for public and private use. This introduction brought about the first real signs of competition within computing history, which helped to spur faster and better development of computers. Their first contribution was the IBM 701 EDPM Computer.

A Programming Language Evolves

A year later, the first successful high level programming language was created. This was a programming language not written in 'assembly' or binary, which are considered very low level languages. FORTRAN was written so that more people could begin to program computers easily.

The year 1955, the Bank of America, coupled with Stanford Research Institute and General Electric, saw the creation of the first computers for use in banks. The MICR, or Magnetic Ink Character Recognition, coupled with the actual computer, the ERMA, was a breakthrough for the banking industry. It wasn't until 1959 that the pair of systems were put into use in actual banks.

During 1958, one of the most important breakthroughs in computer history occurred, the creation of the integrated circuit. This device, also known as the chip, is one of the base requirements for modern computer systems. On every motherboard and card within a computer system, are many chips that contain information on what the boards and cards do. Without these chips, the systems as we know them today cannot function.

Gaming, Mice, & the Internet

For many computer users now, games are a vital part of the computing experience. 1962 saw the creation of the first computer game, which was created by Steve Russel and MIT, which was dubbed Spacewar.

The mouse, one of the most basic components of modern computers, was created in 1964 by Douglass Engelbart. It obtained its name from the "tail" leading out of the device.

One of the most important aspects of computers today was invented in 1969. ARPA net was the original Internet, which provided the foundation for the Internet that we know today. This development would result in the evolution of knowledge and business across the entire planet.

It wasn't until 1970 that Intel entered the scene with the first dynamic RAM chip, which resulted in an explosion of computer science innovation.

On the heels of the RAM chip was the first microprocessor, which was also designed by Intel. These two components, in addition to the chip developed in 1958, would number among the core components of modern computers.

A year later, the floppy disk was created, gaining its name from the flexibility of the storage unit. This was the first step in allowing most people to transfer bits of data between unconnected computers.

The first networking card was created in 1973, allowing data transfer between connected computers. This is similar to the Internet, but allows for the computers to connect without use of the Internet.

Household PC's Emerge

The next three years were very important for computers. This is when companies began to develop systems for the average consumer. The Scelbi, Mark-8 Altair, IBM 5100, Apple I and II, TRS-80, and the Commodore Pet computers were the forerunners in this area. While expensive, these machines started the trend for computers within common households.

One of the most major breathroughs in computer software occurred in 1978 with the release of the VisiCalc Spreadsheet program. All development costs were paid for within a two week period of time, which makes this one of the most successful programs in computer history.

1979 was perhaps one of the most important years for the home computer user. This is the year that WordStar, the first word processing program, was released to the public for sale. This drastically altered the usefulness of computers for the everyday user.

The IBM Home computer quickly helped revolutionize the consumer market in 1981, as it was affordable for home owners and standard consumers. 1981 also saw the the mega-giant Microsoft enter the scene with the MS-DOS operating system. This operating system utterly changed computing forever, as it was easy enough for everyone to learn.

The Competition Begins : Apple vs. Microsoft

Computers saw yet another vital change during the year of 1983. The Apple Lisa computer was the first with a graphical user interface, or a GUI. Most modern programs contain a GUI, which allows them to be easy to use and pleasing for the eyes. This marked the beginning of the out dating of most text based only programs.

Beyond this point in computer history, many changes and alterations have occurred, from the Apple-Microsoft wars, to the developing of microcomputers and a variety of computer breakthroughs that have become an accepted part of our daily lives. Without the initial first steps of computer history, none of this would have been possible.
