Buying a Computer

It isn't fair, but buying a computer is just plain easier for some than it is for others. Those who've purchased and used a computer in the past already have an idea of what they need in a new computer. But those who are new to the computer world could get lost in the myriad of choices available.

The short answer to "What should I buy?" is "The best." Of course that answer is extremely subjective because "the best" to one person is certainly different to another. Our definition of "the best" is the fastest and the biggest, but even that leaves the computer newbie confused. Here's a quick rundown of what the computer novice should do and why.

1. Buy a computer that includes basic peripherals. Every computer can be broken down into four major components: CPU unit, monitor, keyboard, and mouse. For the novice, it's best to buy a computer that has all of these components included so that when it's taken home, assembling the computer is a simple matter of plugging things in where they belong. Save the individual purchases of these components for those who have more experience.

2. Decide what you'll use the computer for. If you want to use your computer for cruising the web, sending email, or performing simple word-processing or spreadsheet tasks, a computer with the basic components that we just described should suffice. If you want to use a computer to help with a career in multimedia however, you're going to need to accessorize your system with a scanner, printer, digital camera, tablet, or digicam for example. If you want a computer to help with a career in music, you will need a quality microphone and set of speakers.

3. Create a budget and stick to it. How much can you afford to spend on a new computer? Although the prices of computers are decreasing, they can still create a hefty expense especially if you need additional peripherals described above. In addition, you'll need to figure in costs for maintenance, servicing, and insuring.

4. Start comparison shopping and look for the "fastest and biggest." By "fastest and biggest," we mean the computer with the fastest processor, the fastest modem, the biggest memory, and the biggest hard drive capacity. Even if you think that you'll never need the amount of speed or space available on the market today, it's important to have in the event that you truly do need that much in the future. Having such a large reserve will cut down on costs when the time comes to upgrade for more than what you may settle for in a computer that offers less.

5. Stick with the better-known brands. Venturing off the beaten path with lessor-known brands is again, an adventure for those who have more experience with computers. Although those better-known brands may be a tad bit more expensive, the computer novice will appreciate the comfort in purchasing a computer from a business that has a long record of building quality products, and that has the funds available for fulfilling returns, trades, servicing, and warranties.

6. Select a store. Having an idea of what you want in a computer and what kind of computer that you want, your only task left is to select the place in which you want to buy it. There are a number of places available including computer store outlets, online stores, auction sites, used computer stores, or your friendly neighborhood yard sale. For the computer novice, we recommend buying a computer from a physical store. In a physical store, you have the opportunity to see the computer of interest in person and ask questions. New computer buyers also have access to store warranties, returns, trades, and services.

These suggestions should give the computer newbie a great start in selecting a quality computer for the first time and they apply to either Windows computers or Apple Macintosh computers. After making these decisions and finally selecting one that fits your needs, you can then venture into the fascinating world of software - a world that is just as grand as the world of hardware!

Top 5 Tips: How To Make Your Laptop Battery Last Longer

Laptops are the pinnacle of mobility computing. When you have power. Battery life in laptops slowly deteriorates over time, because of the way laptop batteries store and use power. No matter if you buy your laptop online, off-line and no matter what sales person tells you otherwise. Even if you left the battery out of your laptop, you might still notice a difference in usage times over a period of years, check Battery University for more information on battery storage. But following a few simple tips can save your battery life. Note: This also works for phone batteries as well.

1. Charge the battery early and often.

Lithium-ion (Li-Ion) batteries will lose charge from age, but recharging it early and often makes sure that the charge is kept throughout the cells.

2. Don't Frequently Discharge and Recharge the battery.

This is called a “Deep Cycle” and should be only be done every 30 – 40 charges to re-calibrate the battery meters in the electronic device.

3. Take out the Battery when using the laptop plugged in for an extended period of time.

Batteries are more affected by heat than any other factor. The heat produced by a laptop is designed to keep it away from the battery, but if you don't need the battery in, it's better to take it out and store it somewhere away form the heat produced by the laptop. Preferably in the fridge or freezer*

4. *The battery should never be frozen.

Although the freezing point of Li-ion batteries is around -40 degrees C, (way below what most conventional freezers), when storing the battery just make sure it'll never reach those sort of extreme temperatures.

5. Never deplete the battery to below their minimum voltage (2.4 – 3.0V per cell)

With these few tips, you should be able to keep your laptop, no matter what brand, continually performing well. Battery life also depends on what operating system, programs and strain your putting on your computer.

Computer Data Loss Prevention and Recovery

For most individuals and businesses, data loss happens. Even the most established technology companies with expert experience in network and laptop security, accidents and hacks happen and data is lost. With the right support and preventative measures, however, losing information doesn’t always have to end in disaster. By making information safety a priority of your computer IT staff and for the employees who use your equipment, data loss can become a rare occurrence.

Preventing Data Loss

Most causes of work station (laptop or PC) data loss can be attributed to human error, physical malfunctions and hardware failure. The Boston Computing Network characterizes data loss into four different types: human error (overwriting a major file), file corruption (virus attack), hardware (fried hard drive), and site-related (earthquake causes coffee to spill on laptop).

For an IT staff member, preventing data loss within a company means making sure employees are:

- using equipment with up-to-date antivirus software
- securing their laptops both physically and electronically with computer locks and good passwords
- backing up their work onto a secure storage device
- using a surge protector and uninterrupted power supply (UPS)

Additionally, computer IT staffers need to have a best practices document in place that employees can follow related to how to handle incoming email, working outside of the office, and traveling. The document should describe how employees can avoid data loss through phishing scams, when and how they should use other wireless networks and how to protect company laptops from theft. By giving employees the information they need to prevent data loss, companies can stop many problems from every happening.

Recovering Lost Data

So much information flows electronically now that it is likely some data loss scenario will occur in a business. Whether it is a major server loss or a small problem on a single hard drive, there are certain things that should be done to avoid making the situation worse.

- Don't: Use the system restore or system recovery setting on the computer. This will not bring your info back instantly

- Don't: Implement an off-the –shelf system recovery software on your own. If you use the incorrect type of software, you are likely to ruin your chances of recovering any information.

- Do: Contact a computer it specialist or tech professional to attempt to restore the data safely and correctly

Many IT and computer services offer continued preventative maintenance and care, but in the case you don’t regularly use an outside IT service, contact one as soon as you realize a problem has occurred.

In addition to dealing with data recovery, IT and computer services provide a vast array of additional preventative measures for combating data loss. For instance, many IT service providers will offer security and back-up solutions like electronic data storage, information security, server support, desktop support, and networking.

Recovering lost data is not always possible but there are ways to reduce the chances of complete loss.
