Dell computers
Dell Incorporated, producer of a large family of Dell computers was found by Michael Dell. While still a student at the University of Texas at Austin, he founded the company as "PC's [sic] Limited" in 1984. He founded the company on the principle that by selling personal computer systems directly to customers, PC's Limited would best understand their needs and provide the most effective computing solutions to meet those needs. In 1985, the company produced the first computer of its own design (the "Turbo PC"), which contained an Intel 8088-compatible processor running at a speed of 8 MHz. It advertised the systems in national computer magazines for sale directly to consumers, and custom-assembled each ordered unit according to a selection of options. In 1987, PC's Limited set up its first on-site-service programs in order to compensate for the lack of local retailers prepared to act as service centers. Also in 1987, the company set up its first operations in the United Kingdom, eleven more international operations followed within the next four years. The company changed its name to "Dell Computer Corporation" in 1988.
In 1990, Dell Computer tried selling its products indirectly through warehouse clubs and computer superstores, but met with little success and the company re-focused on its more successful direct-to-consumer sales model. In 1992, Fortune magazine included Dell Computer Corporation in its list of the world's 500 largest companies. In 1999 Dell overtook Compaq to become the largest seller of personal computers in the United States of America. To recognize the company's expansion beyond computers, the stockholders approved changing the company name to "Dell Inc." at the annual company meeting in 2003.
Dell computers product lines
1) The OptiPlex™ line of desktops, targeted at the corporate, government and education markets. These Dell computers typically contain Pentium CPUs from Intel, although some models are available with Celeron CPUs as well. They contain business-oriented components (such as Gigabit ethernet, which is only available on Precision, OptiPlex and PowerEdge systems) and software.The OptiPlex series comes in four forms - Tower, Desktop, Small form Factor, and Ultra Small Form factors.
2) Dimension - home desktop computer series. As of late 2005 Dell has split its consumer desktop computers into two lines, Dimension and XPS.
3) Inspiron - a laptop brand for individual market.
4) Latitude – a laptop brand, specifically targeted at the commercial market (as opposed to the Dell Inspiron). The laptops have a similar design and parts as the Inspiron model; they usually come with better equipment and software (like OptiPlex desktops)
5) Precision - includes Workstations and "mobile workstations" (high-performance laptops). These Dell computers have better-than-usual graphics components, and comes with Dual-Core Intel® Xeon® processors (usually used in servers).
6) PowerEdge – a line of servers produced by Dell, Inc.. The first generation of these computers was produced in 1996. Currently all of Dell's servers use Intel Pentium or Xeon processors and ship with either Microsoft Windows, SUSE, Red Hat Linux or no operating system preinstalled. There also exists a possibility to get the PowerEdge built per customer specification.
7) The Axim – the newest line of Dell computers. It is a family of personal digital assistants – Windows Mobile-powered Pocket PC Devices.
Best computers
From the first time when a computer was created there is a race between different producers to make the best computer. There is only one question – how does one make something so sophisticated better ?
Originally, computers have been used only for scientific or military purposes – they were simply too expensive for other clients. When required technology became available, they eventually find a way into houses of private users. That's when the real race for creating the best computers really began. But not all computers now are personal computers now – there are still many that fall in two other categories.
First of all – supercomputers. A supercomputer is a unit used to make large mathematical operations- so it’s simple to say, that the very best computer is the fastest one – large amount of memory, powerful Central Processor Units and fast disks. Usually, supercomputer is really a large cluster made of smaller units. Such machines are used by military (US Army uses such machine to emulate nuclear explosions), government and scientific centers all over the world. The best computers in this category are probably still IBM Cray 2 family.
Another type are the servers. They are everywhere those days. From large machines used by IT companies to smaller ones, used for web hosting. The best computer in this category is one that allows many connections, best data flow, and little possibility of malfunctions.
The last, but the most numerous category of computers is a PC family. They are used for many different purposes, and for each of them there is the best computer for it.
First of all - Home PC. It is usually an entertainment machine – used commonly as a media center, to surf the internet, and of course, games. The best computer in this category is usually also the fastest one, or the one with a very good graphic and sound card. Then, there are workstations. Those machines are for work only, and the best computers are ones most suitable for recommended tasks. Programmer will need a different type of machine than an office clerk and people working in a newspaper will need a different type of equipment than is used in a sound studio. The best computers should be chosen only with their future tasks in mind. The last category are the notebooks. It is a completely different type of computers. Again, the most important is a purpose of such equipment. The best computer in this category is not necessary the fastest one – this time it's the weight that matters and the most important thing is duration of work without external power supply.
We have different needs and different tastes. What suits someone best means nothing to others. Moreover, what is the very best computer for one, to other is a useless pile of junk. The best computer for a gamer would be useless for a large IT company.
