How to Buy a PC
Buying your first computer can be an intimidating and sometimes frustrating experience, we've put together some tips to help you along the way. -- Find the best computer to fit your needs.Before You Buy
Before you begin shopping for a new computer, ask yourself the following questions:- "How much money do I want to spend on my computer?"
- "What are my computing needs?"
For example, do you run a small business? Are you children interested in computer games? Would you like to email friends and family?
These answers will help you stay within your budget and find the right computer for you and your family.
Shopping List
It's important to know the general parameters of what you intend to buy.
- Processor (CPU)
- For almost all home computing needs, Intel's affordable Celeron PC or Apple Computer's iMac will be plenty fast enough. However, if you find a great deal on a faster Intel Pentium processor or one of Apple¹s Power Mac G3s, you might want to consider one of these faster processors. Bottom line: Most CPUs will meet your computing needs, so don't pay for too much power.
- Megahertz (MHz)
- Although it is important to recognize your computer's processor type, don't be blinded by the Megahertz (MHz) hype. Typically you'll pay more for the fastest CPUs and -- for basic computing needs -- and won't notice the increase in Megahertz. Bottom line: Don't be overly concerned with the number of Megahertz (otherwise known as the CPU clock speed).
- Memory (RAM)
- RAM is what your computer uses to run (as opposed to store) programs. These days most computers come with at least 256 Megabytes (MB) of memory (RAM), which is adequate for most functions. However, even the most simple tasks, such as word processing, will be quicker if you install more memory. Keep in mind you can always add more RAM to your computer, but it's much easier to have extra memory installed when you buy your PC. And with RAM prices so cheap, you can never have too much. Bottom line: Splurge on more memory.
- Hard Drive
- The hard drive is where you computer stores information -- it's like the trunk of your car. Regardless of your computing needs, chances are you'll inevitably accumulate a variety of software. Playing games, downloading large graphics files and installing software will take up plenty of space on your hard drive. The good news is that extra storage is very affordable and most computers come with plenty of space to hold all your files. Bottom line: Don¹t settle for a small hard drive.
- Monitor
- A shiny new computer isn't going to do much without a monitor. Remember to add in the cost of a monitor when comparison shopping since several manufacturers advertise without including a monitor in their price. These days get an LCD. I say splurge on the monitor and the mouse, these are the only things that interface much with the human body.
- CD-ROM drive
- CD-RW is a must. You may want a DVD-CD-RW.
- Modem
- Most of us want a home computer to get online. Most computers come with a pre-installed modem, just make sure you're getting the fastest V.90 56-Kbps model. Bottom line: Don't buy a computer without a 56K modem and a 10/100 ethernet card/interface.
- Software
- Each computer manufacturer includes a different array of software titles. Make sure you can get your computer up and running without the added cost of buying new software. Bottom line: Build your software library with the included games and programs.
- Service and Support
- Once you take your computer out of the box, you're on your own so it¹s very important to check out you computer manufacturer's technical support services since each company's services vary slightly.
How to buy a PDA
Personal digital assistants devices come in all shapes and sizes, with software and add-ons to go with them. All they have in common is an ability to manage contact details and personal agendas, as well as issue reminders and sound alarms.
Keyboard
Machines come with or without a keyboard. The alternative is a pen which reads characters on a touch sensitive screen. Suppliers generally pitch keyboard-based PDAs more as portable computers than organisers, but once you remove the keyboard they are all more or less the same.
Keyboard-based models are better suited to tasks such as word processing and data manipulation in applications such as spreadsheets. With this in mind the touch sensitive screens learn to read your handwriting making them the ultimate gadget.
Some pen-based PDAs have keyboard attachments which make them a much more flexible option.
The PDA position
Using a PDA is going to be a lot slower than a laptop PC. A PDA processor's headline speed is far from a clear indicator of true power or versatility.
Many other factors need to be taken into account, such as available memory and the demands of the machine's operating system.

OPERATING SYSTEMS
Operating systems are fairly crucial for PDAs as they can often define how the hardware will actually run.
