Do You Feel Used by Computers?

A look at second-user computer equipment.

Let’s dispense with the myths first. I’m NOT talking about the sort of second-hand computers you get from some high street junk shops, or the sort you can buy from free ads newspapers. These are the types that get used computers a bad reputation since there are many dodgy deals to be had!

I’m talking about a different breed altogether,Guest Posting the sort of used computers you’d be proud to own and feel safe buying because they have proper and lengthy warranties on each and every one of them and have been extensively tested and approved.

The criterion is quite strict. Sure, there are any number of companies out there who offer used computers at low prices. Very few offer 12-month warranties however and many of them disappear just as quickly as they arrived leaving you with a problem. All computers, no matter which category they fit in, or what you call them, should be high quality, guaranteed, fully working computers from a reputable supplier.

So, let’s put all the computers into two categories, I’m going to call them ‘used’ and ‘unused’ computers.

1. Used Computers

Second-hand, second user and used computers are what you would expect in that they have had a previous owner. Many of the computers have been returned to the company from which they were bought in the first place. This is ideal as the company has the appropriate expertise and spares already in place to correct any faults they find.

There are a number of reasons why computers are returned:

- businesses, colleges, individuals etc upgrade their computer equipment for the latest model

- the equipment was leased over a set period and the lease expires (so the equipment is returned)

- the computer gets a fault that can’t be fixed quickly so it is swapped permanently out for a new one

- the customer changes their mind just after purchasing

As you can appreciate, ‘used computer’ can mean anything from ‘barely used’ to ‘a couple of years old’. However, once returned the computers go through a rigorous check procedure, have their hard disks cleared or changed, have new keyboards, mice and cables if worn and new cases if they have noticeable damage. If there are any faulty components, such as sound card, video card, floppy drive etc, these are always replaced. These computers are often referred to as ex-lease, open-box, returns, refurbished, reclaimed, remanufactured, rebuilt, recycled, recertified or reconditioned computers. Phew!

At worst, the used computers, as sold on to you, have minor blemishes, scratches, dents or wear. This is always just cosmetic and does not affect either the performance or value of the computers in any way. What you receive is a fully-working computer, the same working condition as new, but at a price well below that of new. You can often pick up recent high-specification models second-hand and save hundreds of pounds. Of course there are lots of bargains to be had whatever model or type you decide to purchase but note you will sometimes find it difficult to get anything as stock can go very quickly some weeks.

2. Unused Computers

The other main categories of computers are the overstock, surplus, liquidated, superceded, discontinued, open box or end-of-line stock. These are all basically the same in that they are all UNUSED computers. So these are not what you would really classify as second-hand, ie they have not personally been owned and used by any business, college, individual etc. They will often be in their original packaging.

The reasons why these computers come on to the market are because:

- a manufacturer has brought out new models and wants to get rid of the ‘old’ superceded stock in his warehouse

- a store wants to raise some urgently needed cash and sell his unsold stock

- a factory or store becomes bankrupt and the computer stock is sold

In most of these cases, the stock gets sold to specialist dealers who buy in bulk and who then sell it on to the public, businesses etc. They then either provide a new warranty themselves for the equipment, or ensure there is a full warranty from the original manufacturer. You’ll often find Toshiba, HP, Compaq and other brand name computers offered with a 12-month warranty from the original manufacturer. Note that sometimes suppliers refer to open box as meaning refurbished – they will usually state in the description what they mean.

So that’s it. Two main categories of computers, quite different from each other but both offering great deals on branded equipment. Either way you will save money and still get a peace-of-mind guarantee on your computer purchase.

The Evolution of Technology – The History of Computers

By Rebecca Blain ofhttp://www.build-your-own-computer-tips.comWhile computers are now an important part of the lives of human beings,Guest Posting 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 t
