Conventionally a computer consists of some form of memory for data storage, at least one element that carries out arithmetic and logic operations, and a sequencing and control element that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from external source, and allow the results of operations to be sent out.
A computer's processing unit executes series of instructions that make it read, manipulate and then store data. Conditional instructions change the sequence of instructions as a function of the current state of the machine or its environment.
The first electronic computers were developed in the mid-20th century (1940–1945). Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1]
Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into mobile devices, and can be powered by a small battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.
Love 'em or hate 'em, computers have drastically changed our lives. And in an advancing technological world, more and more traditional ways of being are getting digitized for consumption on your (you guessed it) computer. From online shopping to making new friends, running a business or just running your life, computers are a vital asset to succeed in modern day society. But still, for many computers are an enigma. So here's a basic primer on where computers have been and, more importantly, where they are going.
Computer History
The story of the personal computer, or a computer designed for in-home consumer use, began in 1970 the
Kenbak-1. (Isn't is crazy to think that less than 50 years ago these now life-necessities were only a science fiction fantasy?) A short lived run of only 40 computers or so, the Kenbak-1 sold for roughly $750. But the first real functional personal computer came from the Computer Terminal Corporation with its Datapoint 2200. This computer terminal box featured the now-familiar screen, keyboard and programmable storage capacity component. Early forms of computers, called "microcomputers" were downright expensive and cost-prohibitive for the masses. It's no surprise, though, that the personal computer revolution really launched with the introduction of the Apple Computer Company and its 1977 Apple II model. The Apple II was the first computer to offer color graphics, sported 4kb or RAM (yes, that's kilobytes) and sold for around $1300. The Apple II computer became the first mass produced microcomputer from Apple. In fact, it wasn't until then that the concept of the computer being a household fixture became a reality. Get this - by 1993 between five and six million Apple II computers were made!
Of course IBM had to get in on the action, and in 1981 IBM introduced its IBM PC - featuring an operating system known as "DOS" made by a small, 32-person company known as Microsoft. This marked the competitive development of the modern day computer. From this point on, the world of computers took two sides. On one side was Apple Computer and its Macintosh line of computers. On the other, the army of personal computers whose ranks included not only IBM, but eventually names like Gateway, Dell, HP, Sony Vaio and Compaq.Desktop vs. Laptop Computers
When buying a computer, the biggest choice is deciding between a desktop and a laptop. So really what's the difference? Of course the most obvious difference is with a laptop you can take your computer with you, whereas a desktop has to stay at home or in the office. But beyond portability and size, the decision between a laptop computer and a desktop is a decision of personal preferences.
First, there's the price tag. Most laptop computers are more expensive than their desktop computer counterparts.
And, as with any high-price piece of technology that can be easily taken with you, laptops are a prime targets for theft. Needless to say, desktop computers are rarely stolen.Due to the compact nature of a laptop, its computer parts are what is known as proprietary. This means that if something in your laptop computer stops working, only the computer manufacturer can fix it - a service that is anything but cheap. Decide to fix it yourself, and chances are you'll void the manufacturer warranty. On the other hand, desktop computers can be fixed at your local computer store, often at a much more reasonable price.
So who are laptop computers geared for? Unless you are somebody who is always on the go - and need to have your computer with you, a desktop computer might make more sense. And if you only use computers to check and send emails, perhaps a handheld computer or a PDA might be a better choice for you.
Dell Computers
The Austin, Texas based Dell Computers was founded in 1984 by then college student Michael Dell. With $1000 and a dream, Dell set out to bypass the middleman and sell computers direct to the public. Dell computers'
success today are based on are business computing, home computers, service and technical support. Some of the more leading computer models Dell introduced to the market include the OptiPlex office desktop computers, Vostro desktops and laptops for small businesses, Latitude commercial laptops, the XP and Linux-based Precision workstations, consumer desktops and notebooks named Inspiron and the performance gaming focused XPS.Although Dell is heavily tied to the Microsoft Windows computer operating system, it did flirt with the concept of making Linux - a competing open source operating system - available with its products. However, by 2001 this short-lived romance was called off.
HP Computers
Hewlett-Packard, or HP Computers, is another leading personal computer and laptop computer manufacturer. When HP computers merged with Compaq in 2002, it expanded its computer services from hardware and software to computer support and services. HP's line-up of personal computers includes such leading models as the HP Pavilion, Compaq Presario and the VoodooPC. The HP Pavilion comes in both a desktop and laptop
make. Offering models for business productivity as well as entertainment performance, the Pavilion computer is a great computer option. Acer Computers
Taiwanese computer manufacturer Acer Computers, is one of the world's top five largest personal computer manufacturers, with a lineup that includes personal computers, laptop computers and a wide range of computer accessories, software and components. Acer is best known as a laptop computer manufacturer with a wide range of affordably priced laptop computer makes and models. Some of its leading products include the TravelMate, Tablet, Aspire, Alto and Extensa series.
Of course, these computer examples aren't the breadth of what the market offers. If you're auditioning new computers, decide what you'll be using the computer for first. This will help you identify what you really will require from your computer. For example, if you plan on working emails and hitting the internet, you won't need as much performance as someone heavy into graphic design or computer gaming. Plus, you may be contemplating whether or not to invest in a PC or a Mac. These are all important questions to answer. Do your homework before you buy and chances are you will find the right computer for you.
