How to Install a Wireless Communication Card on a Laptop
With PCMCIA cards, insert a communication card into the laptop. Then you are able to telecommunicate from all over the world.
Ejecting the Card Steps:
1. Press the PCMCIA card Eject button.
The card should pop out slightly.
2. Gently slide it out the remainder of the way out. Within a few seconds the computer will make a sound confirming that the system recognizes that the card has been ejected.
Installing a Communication Card Steps:
1. Open the panel labeled PCMCIA on the left side of the computer.
2. Insert the card into the slot. The edge of the card with the roll of connection holes must go in first. Check the card's markings to determine which side should face up. If the card doesn't have any markings, slide the card in label up.
3. Don't force the card into the slot. If it doesn't go in easily, then you have not inserted it correctly. The card is fully inserted if the Eject button to the right of the slot pops out. Within a few seconds after the card has been inserted, the computer will make a confirmation sound. If there is no sound, then you have turned off the computer's speaker or the basic PCMCIA drivers have not been properly loaded.
Tips to remember:
Some types of PCMCIA cards may require the installation of special drivers. These drivers should be supplied by the card manufacturer.
When inserting a PCMCIA card into the slot, the computer will go to sleep. This is necessary to maintain a link between the system and the card just inserted.
How to Select Wireless Communication Cards for a Laptop
Free yourself from the phone line by getting a wireless communications card for your laptop. To select the card, you need to know how you will use it and what type of computer you have.
Steps:
1. Determine whether you'll be connecting your laptop to a local-area network (LAN), such as at your dorm room. You should also decide if you need to make a LAN connection from the road.
2.-áFigure out if you need to connect via an ISDN line.
3.-áDetermine if you're using a notebook PC with 32-bit card slots or with 16-bit card slots or if you're going to be using an Apple PowerBook.
4.-áAsk to see the wireless communication cards based on your evaluations.
How to Decide Between a Laptop and a Desktop
When deciding between a laptop and a desktop computer, weigh your computing needs against the benefits of each type.
Steps:
1. Determine if you really need to take your computer around with you (you go on many business trips, for example). If so, buy a laptop computer.
-á2.-á Determine if you have a slight need for portability, or if lack of space is a concern. If so, consider one of the new "slim-top" or "slim-line" desktop computers.
-á3. Expect to get much more speed and functionality from a desktop computer, for the same price as a laptop.
-á4. Expect more expensive and frequent repairs with a laptop computer.
-á5.-á Buy a desktop computer if you'll be working with graphics or multimedia or playing action games, as laptop screens are small and low-resolution.
-á6.-á Choose a desktop computer if you need upgradability.
Tips:
Unless you're a student, buy a laptop only if it will supplement a desktop computer. A laptop is difficult to work on for extended periods of time because of the small screen and small keyboard.
Expect a laptop to have considerably higher resale value than a desktop.
-áAt the same clock speed, laptop processors are slower than desktop processors.
How to Decide Whether to Purchase a 'New Technology' Product
Should you buy a flat-panel monitor, a DVD-A or SACD player, a digital television, digital Internet service (DSL, cable, satellite), or other purportedly better consumer technologies? If so, should you be an "early adopter," or should you wait for widespread public acceptance of the product, lower prices, and removal of bugs? How should potential obsolescence influence your purchase?
Steps:
1. Remember all the consumer products that failed to become popular, such as DCC (digital compact cassette), remote controls for computers, Internet telephones, and DIVX DVD players.
-á2.-áRemember all the consumer products that only sold for a few years because they were superceded by better technology, such as 8-track cartridge players, laser disc players, and Commodore computers.
-á3.-áRemember all the good technologies that were squeezed out by superior marketing strategies by manufacturers of competing technologies, such as Betamax VCRs and dbx noise reduction.
-á4.-áConsider the convenience and ease-of-use of the new product; these factors usually prevail over quality in the marketplace (for example, digital answering machines have inferior voice quality but are easier to deal with).
-á5.-áThink about retail changes necessary for a product to succeed. For example, will stores need to stock redundant software titles, and are they likely to do so?
-á6.-áFind out how much software is available, if the product uses removable software (such as DVD-ROMs). Decide if you can buy enough software now to justify your investment.
-á7. Find out what technologies will compete with the one that interests you, and which is likely to be better.
-á8.-á Look for reasons why the technology might be flawed, or too gimmicky or complex to succeed.
-á9.-áEvaluate the quantity of advertising and marketing. Decide if promoters of the new technology are marketing it aggressively enough to ensure its success.
-á10.-á Evaluate manufacturers' ability to control the marketplace. Analyze if they can discontinue production of one product (such as vinyl records) to force the success of another (such as CDs).
-á11.-á Make sure that several manufacturers will introduce products, and that the original manufacturer will license the technology to competitors.
-á12.-áExpect the first products on the market will lack the performance quality and features of the next generation.
-á13. Remember that prices will be high until product sales warrant mass production - if that happens.
-á14. Make sure the product does exactly what you want it to do, and that a more functional product (for example, one that will record as well as play) isn't on the horizon.
Tips:
Gain knowledge of the manufacturer's track record. It can be a deciding factor.
The new digital technologies are superior to the current analog technologies only half of the time. They usually have less production costs and are more convenient.
