Computers - how they have advanced

Even over the last decade, the advances in computer technology have been immense

Even over the last decade, the advances in computer technology have been immense. Computers can do more today than ever before, faster and at a better value price. Unfortunately, this also means that shopping for a computer can be confusing, as it is hard to know what you actually need and what is just an extra that’s nice to have. Hopefully this article can clear up a few of the mysteries for you.

First of all, let’s look at processors. The two main companies producing processors today are Intel (Pentium processors) and AMD (Athlon processors). Although fanatics on each side swear otherwise, there is little difference between them, performance-wise. In almost all cases, more expensive processors will simply run faster.

However, it is important to consider that the performance of your processor can be limited by how much memory (RAM) your computer has. For high-end processors, you should make sure to get at least a gigabyte of RAM, although lower-end systems will be fine with less. RAM is especially important if you plan to use the system for gaming or other graphics-intensive applications.

Hard disk space, at this point, probably isn’t worth caring too much about. Even the cheapest computers now come with ridiculous amounts of hard disk space, far more than you are ever likely to use. It is much better to upgrade to a DVD re-writer drive than to upgrade your hard disk space. DVDs hold so much data that however big your hard drive is, it is unlikely to hold more than a cheap spindle of DVD-RW discs – and they’re re-writable, so you only need to buy them once.

The only other thing you really need to worry about is the graphics card (sound cards are all the same these days). Again, if you’re going to be doing anything graphically-intensive, then research this further and get a good one (be warned that it can be expensive). For the average user, though, the graphics card that comes with the processor is likely to be fine, even for many less-demanding or older games.

Computer Hardware: Desktops and Notebooks and Handhelds - Oh My!

Even though computer hardware is central to almost everything we do, it's easy to lag behind in the advances made in both hardware and software.
Computers have become ubiquitous in almost every facet of our lives. At work, desk jockeys spend hours in front of their desktops, while delivery people scan bar codes with handhelds and workers in the field stay in touch with the central office via their notebooks. At home, we rely on our desktops and notebooks to do our shopping, to entertain us, and to keep us abreast of world events. We may not see our email servers, but we count on them to deliver our email whenever and wherever we want it. Our PDAs keep track of our hectic schedules, our to-do lists, our contact lists, and even entertain us with games while we're waiting for an appointment or to board a plane. Computer hardware weaves itself through the fabric of our lives.

Even though computer hardware is central to almost everything we do, it's easy to lag behind in the advances made in both hardware and software. Desktops that are four or five years old, for example, become obsolete. You may be able to upgrade operating systems or buy computer add-ons to extend the life of your desktop, but at some point the software, applets, and plug-ins you need to get the most out of your computer simply won't support your old machine.

If it's time to get new computer hardware - whether desktops, notebooks, or PDAs - you'll be amazed at the computing power and the crisp displays that are available, as well as the incredible low prices. Take some time to shop around, and you'll soon discover that online computer hardware sources will save you money over traditional retail stores. When you think about it, it makes sense. According to logic, direct sales cut out the middleman and can pass along the savings to the consumer.

If you're in the market for new desktops, notebooks, or PDAs, there are a myriad of choices. Here's a rundown of some of the best systems available:

Desktops: First, you need to decide - as the advertising campaign so cleverly drives home - if you're a Mac or if you're a PC. If you're a Mac, the iMac Desktop with a 20-inch display can be found for just under $1,500. That includes a 2.16 GHz Intel Core 2 Duo, 1 GB RAM, a 250 GB hard drive, and a SuperDrive.

If you're a PC, the Hewlett-Packard Pavilion S7700N Slimline Desktop PC includes an AMD Athlon Processor 3800 Plus, 1 GB RAM, 250 GB hard drive, SuperMulti DVD Drive, and Vista Premium - the new Microsoft operating system. Price? You can find it for a little over $600.

Notebooks: If you love Macs, you'll adore Apple's PowerBook at just under $2,500. With a 15.2-inch screen at 1280 x 854 resolution and TFT widescreen display, the PowerBook gives you a lot of bang for your buck. It runs on a 1.67 GHz PowerPC G4 and 512 MB RAM, and has an 80 GB hard drive and a SuperDrive.

In the PC universe, the Toshiba Satellite A135-S4427 is a perfect example of the computing power you can get at a very low price. The 15.4-inch widescreen notebook has an Intel Core Duo Processor T2250, 1 GB RAM, a 120 GB hard drive, a SuperMulti DVD drive, and Vista Premium - all for around $900.

When it comes to computer hardware, it pays to shop online. Desktops, handhelds, PDAs, notebooks, servers, and even software can be found at incredibly low prices - so low that you'll want to upgrade all of your computer hardware to the fastest, clearest, best systems available.

5 Reasons To Purchase Desktop Computers

If you are in the market for a computer, there are a number of factors to consider.  Will it be used for your home, your office or perhaps even your home office combo?  First off, you will need to set a budget for your new purchase before deciding whether to shop for notebook or desktop computers.  Many offices use desktop computers because they are not intended to be moved around a lot.  In addition, affordability often plays a large role in someone’s decision as to whether to purchase notebook or desktop computers.

While you are shopping around, it’s important to keep in mind some of the benefits that go along with owning different types of computers.  To that end, this article provides five important reasons to purchase desktop computers.

- Desktop computers are typically much more affordable than notebook computers.  With notebooks, you are paying more for the convenience of portability.  For as little as $299.00, desktop computers can be purchased from one of the leading manufacturers and a notebook computer for as little as $499.00.
- Unlike notebook computers, replacing a keyboard, mouse, speakers or even a monitor does not require having your computer serviced by a professional repair shop.  Because notebook computers have everything built in, including the aforementioned features, it is more difficult to replace a keyboard or monitor as opposed to desktop computers, which operate on external connections.

- In the event of an unlawful entry into your home, desktop computers are not as likely to be stolen because of their weight and bulk.  Notebook computers, on the other hand, are small and portable.  This, alone, makes them more appealing to a thief than desktop computers.

- Desktop computers are stationary by nature.  Unlike a notebook computer, which can easily be moved from room to room, they are less likely to be dropped or broken because they are not moved as often.

- The vents on desktop computers are located on the back of the tower, which allows for proper ventilation that will help to prevent the computer from overheating.  Notebook computers, on the other hand, feature only one vent on the back with the remaining underneath the base.  If placed on a table, the air vents can become blocked and the computer may overheat.  If prolonged use leads to overheating, damage may result.

When choosing from the many desktop computers on the market, always make sure that you purchase from a manufacturer who has experience in creating computers.  Even though they are more affordable than notebooks, desktop computers are not cheap.  With an investment that involves several hundred dollars, you will want to consider the length of time the manufacturer has been in business, their reputation with customers and their warranty. 

Additionally, when choosing any system, including desktop computers, always look at the potential for future upgrading.  As you grow, you will want your computer to grow with you and a part of that will include a slight upgrade from time to time.  This is the only way to get the best use of your desktop computers and make sure that your investment is one that lasts for years to come.
