The Benefits To Owning A Refurbished Laptop


If you like having the latest and greatest, then refurbished is not for you. However, if you don't mind minor cosmetic damage, and the fact that someone else has used your laptop, then you may want to consider purchasing a refurbished laptop. But why would anyone want to purchase a refurbished laptop as opposed to a brand new one? In this article, I will tackle this very issue, and give 3 reasons why you should own a refurbished laptop.

The first reason why purchasing a refurbished laptop may be a good idea is that they are a lot less expensive than their newer cousins. Of course, refurbished implies that it has seen prior usage, so refurbished laptops are generally older models, and you don't always know how their previous owners took care of them. But refurbished also implies that someone has taken the time to fix, and often times replace, any broken components. Do some research and only buy from reputable sources.

The second reason why you may want to purchase a refurbished laptop is that, because of their low cost, they are more expendable than new models, and make a great second laptop. As I explained above, refurbished laptops are generally a lot cheaper than a new laptop so if something should happen to it, you're only out maybe a few hundreds dollars as opposed to a new laptop which could cost you thousands.

The third reason why you may want to consider purchasing a refurbished laptop is that since you'll be spending a lot less money on the computer itself, you can afford to spend more upgrading it with newer, and better components. For example, you can add memory to speed it up, or upgrade to a larger hard drive. You should, of course, make sure that your computer can support these upgrades before you even purchase it. If it can't, then look for one that can before making your final decision.

If you decide to purchase your first refurbished laptop, make sure you do plenty of research. Refurbished means used, and you don't kow how the previous owner took care of it. Buy from a reputable source that offers some sort of warranty. Most won't warranty the battery or software but will provide at least a 30 day warranty for most of the hardware.

I've discussed three benefits to owning a refurbished laptop. They are low in cost, make a great second laptop, and you can spend more on upgrading the components. Make sure to do your research before you buy, and owning one will be a pleasant experience.

All About Accessory Computer


A home away from home is a great thing, so why not have an office away from the office too?The spare room or a quiet corner can be a perfect place for productivity. To outfit your workspace, you might need to invest in some new hardware like a second computer, a bigger monitor or a high-quality printer. Once you've got your home computer set-up, you'll need to connect it to the Internet or network it to other computers and peripherals in the house. With a good grasp of the facts and a firm idea of your work habits, you'll be ready to make sensible choices for your home-made office.

• The Computer. Not everyone needs the same level of performance in a home office computer. You might use your computer primarily for word processing and email which requires little processing power. On the other hand, you may want more power to run database analysis, large spreadsheets or graphics applications. The type of work you do and your work load will determine whether you need a computer with a lot of brawn or just a little.

• Processor. A computer's processor or central processing Unit (CPU) is the engine that powers the device. The speed of the processor is called the clock speed which measures how fast the processor can carry out instructions. Speed is measured in MegaHertz (MHz) and is one measure of a computer's power. A typical home office Windows PC should have at minimum a 500 MHz processor. A power user would probably prefer 800 MHz or higher. If you know your computing needs are modest, and you want to save some money, an older machine with a slower processor is worth considering. When looking at an Apple Macintosh, keep in mind that you can't simply compare processor speeds with Windows machines, as the two types of computers have different system designs. Macs generally have lower processor speeds in MHz but don't let that fool you. Newer Macs like the iMac can definitely keep pace with PCs.

• Random Access Memory (RAM). When the computer is turned on, RAM is used to hold the operating system, applications and data that you're currently running. Information in RAM is rapidly available to the processor. When RAM fills up, the computer slows down because it now has to retrieve information from the slower hard drive. Imagine documents on your desk in front of you, readily at hand when you need them. But when your desktop is full, you have to file and retrieve documents elsewhere, which takes more time. The amount of RAM you need is influenced by the type of applications you use. Graphics programs like Adobe PhotoShop or Illustrator use a fair bit of memory. Word processing and spreadsheet programs use somewhat less memory. Users who like to multi-task and prefer having multiple applications running simultaneously will definitely want plenty of memory. More memory gives you a larger "workspace" and makes your computer perform faster with fewer glitches. A typical user needs at least 64 MB of RAM with 128 MB becoming the norm. In virtually all computers, you can expand the memory as you need more.

• Hard Drive. This is the computer's filing cabinet where all your applications and data are permanently stored. Most users can fit many years of productivity into a 6 to 10 GB hard drive. If you need to store a lot of information like several years of business records or image catalogues, then you may want a more spacious hard drive. Luckily, a bigger hard drive won't cost you that much extra. Alternately, you could invest in a removable storage drive.

• Expansion. It never hurts to get a system with room to grow, especially if you foresee your home office needs evolving. Find out how many RAM slots a system has and what the maximum amount of RAM is. Adding expansion cards to your system for 3D graphics or ethernet will increase the functionality of your computer. Look for a system with two or three free expansion slots and room for additional disk drives.

Understanding Operating Systems


Every new computer that's brought home from the store has an operating system installed onto it. But what most new computer users don't realize, is that without an operating system, that computer would be a simple shell of possibilities. A powered computer lacking an operating system wouldn't display anything more than a bunch of confusing text messages that describe the computer's boot process. At the very end of this process, the computer looks for an operating system and if not found, it will prompt the user to tell it where it is.

Earlier computers didn't have an operating system and if you have experience with the computers of the early eighties, you'll remember that most to them didn't even have a hard drive! These old computers booted an MS-DOS type operating system from drivers stored onto a floppy disk, and in order to use a program, users would remove the boot floppy and then insert a new floppy that contained the program. The floppy not only stored the program (word processor, spreadsheet, etc.), it also stored the drivers that the program needed to communicate with the computer's hardware. As you can imagine, the cumbersome process of switching from floppy to floppy prompted the birth of the operating system.

An operating system is a software program that controls how the computer's hardware (and installed software) works. It manages the activity of every component and then displays that activity as a user-friendly interface (GUI). It keeps track of where things exist on a computer's hard drive as well. But perhaps most importantly for the end-user, the operating system is responsible for translating commands issued with a keyboard and mouse into binary code (010110101 stuff) that can communicate with a set of speakers, a printer, a scanner, and more.

With an operating system installed onto a computer's hard drive, users no longer need to boot a computer with a floppy disk, nor do they need to run programs from a floppy disk. All the drivers of a program are stored onto the computer and used whenever a program is started.

Apple's Macintosh computer was among the first of a couple systems to establish a user-to-hardware relationship through a user-friendly interface. Today, we have quite a few operating systems. Some of the more popular ones are Windows Vista, Mac OS X, ZETA, IBM, Unix, and Linux. But even still, operating systems have extended onto to non-computer devices such as game consoles, portable music players, and PDAs. Regardless of the device, the operating system installed onto it serves the same purpose across the board: to enable user-to-hardware communication.

When you think about upgrading your computer to a new operating system, be careful to make sure that you have the necessary hardware components. We tried to upgrade one of our Windows 98 machines to Windows XP, but we were cautioned that the former may not be hardware compatible with XP technology. Apparently, the Windows XP operating system requires components that weren't developed at the time Windows 98 was distributed and if we were to install Windows XP on this machine anyway, the new operating system would look for hardware that the computer didn't have. And that would be an instant recipe for failure.

Also be careful about installing operating systems that are incompatible with existing hardware. The hardware of Macintosh computers is extremely different from the hardware of Windows computers and under no circumstances will a Windows operating system work on a Macintosh machine!

Protecting Children Online


It's an unfortunate fact of reality, but children are the most victimized computer users on the Internet today. The good news is that there are some practical steps you can take to protect your children from sexual predators, hackers, and other seedy individuals who want to cause harm. This article will describe a few of them.

The first step in protecting your children at the computer is to prevent their access to passwords. This will keep them from sharing passwords with others and inadvertently enabling hacking into your system. If you think about it, there's no reason why a five, seven, or even twelve year old needs to know the passwords to sensitive areas on the computer unless you've given them permission! In fact, children don't need to know the password used to access the Internet either. It may be a hassle to type it in each time they want to get online, but it's better to know the times that they connect than to have them sneak online without your permission and knowledge of their activities.

The second step towards protecting your children online is using the computer together. Siting next to your child while he or she peruses the Internet, you can guide him or her to make safe and intelligent decisions. You can approve websites and bookmark them together. You can monitor the conversations your children have with their friends and teach them appropriate online behavior at the same time. You can make recommendations and create a private time for quality time as well.

The third step involves blocking access to inappropriate areas altogether. You and your children may not always agree about what's appropriate, but as a guardian, you're in control and you're ultimately responsible for their safety. Take the time to investigate software tools that put you in control and allow you to block access to certain websites. If you use an online service like AOL (America Online), you can use its internal Parental Control settings to block access to various chatrooms and websites. You could even block instant messaging and email from anyone who isn't a fellow AOL user.

Other tools available online operate similar to the way that AOL's Parental Control settings work, however no collection of tools could replace the reinforcement of mom and dad. Never let your children speak with strangers and never leave them alone at the computer unattended. Children just don't have the experience that adults have and they don't have the skills required to handle inappropriate conversations, emails, or images found online.

NOTE: Some of these tools include kid-specific web browsers that will visit pre-approved websites. Others include browser plug-ins that won't allow access to online areas that contain forbidden keywords.

Another step requires teaching your children to never ever volunteer personal information. Under no circumstances, should children give their personal names, home addresses, phone numbers, or school information to anyone over the Internet regardless of the situation. In the even this information is required to enter a contest of some sort, be sure that you're the one who makes the decision to supply it and that you're the one who does it.

Performing all of these steps won't be easy. However you can help minimize resistance to your monitoring efforts by explaining why you're taking these precautions. Smaller children will probably enjoy the time you spend together at the computer, but older children and pre-teens may resent it. To help build a case for your concern, you might want to show your older children a few news stories that exemplify the dangers that unsupervised children are exposed to. The newspaper is unfortunately full of examples but with your help, we can reduce them world-wide.

Networking Home Computers

Have you ever thought about networking your computers at home? If you have a small collection of computers around the house (and a small collection of computer users), you can connect each one of those computers to one another and share data, software, and hardware including a single Internet connection. There are many creative uses for home networking, however it's an ideal situation when upgrading each computer to the same capability is financially out of the question. On a home network, each computer has access to the equipment of the better machine in the group as if that equipment were their own.

Connecting computers with either an Ethernet cable or a Wireless connection can create a home network. The easiest and cheapest method uses an Ethernet connection, which requires a series of network cards, a cable for each computer, and a router. The network card is similar to the old modems we used in the past to connect to the Internet, however in a home network, it's used to communicate with every computer that's connected to it.

You'll want to first, select the computers that will connect to each other and then install the network cards inside each of them. Then you'll connect a cable to each computer that will communicate with the server. These cables won't connect to the server directly. Instead, they'll connect to the router. To enable Internet access for each computer, this router will need to connect with a modem of the host machine.

Once the hardware is set up correctly (you'll need to read the instruction manual of your equipment for details), you can then setup the network from Windows on each machine. Within Windows, you can set up a home network similar to the way that you set up an Internet connection. Only this time, you'll set up a LAN (Local Area Network) connection.

Windows should walk you through setting up a LAN after starting the computer and once complete, you can begin to connect one of your machines to the network. You can do this through Internet Explorer by typing in the address and password required to access the router (the address and password required to access the router will be in the router manual).

Connected to the network, each computer can send files back and forth, open programs on a remote computer, play the sound files and videos located on another computer, and share a single Internet account to browse the web, download files, or chat with someone in an entirely different country. If a single printer is available on only one computer in the network, every connected PC can send documents to it and print them out. Kids will enjoy the ability to play multi-player games and adults will enjoy the ability to blast a single message to everyone at once or maintain a group schedule.

Since we're describing a home network that will connect to the Internet, you're strongly advised to install a protective firewall program to thwart Internet viruses, worms, or other damaging spyware code. Firewalls prevent - but they don't repair. Only anti-virus and anti-spyware programs can reverse damage. So you should install a firewall on the computer that grants access to the computer, and then install an anti-virus and anti-spyware program on each of the remaining computers in the network.

If you have files that shouldn't be shared (bank statements, credit card information, etc.), you can restrict their access in one of several ways. You can put them in a new folder and then remove the "read" permissions for that folder. Or you can specify who can (and who cannot) access specific files with a password from within Windows Control Panel.

Smartphones, What's the Craze All About?

If you haven't heard of smartphones, we'd like to learn where you've been hiding all this time. Smartphones have been all over the news and chances are, you do know what they are - only you know them under a different name. Smartphones are mobile phones with computer like capabilities.

What's that? Aha! Yes, you've not only heard of them, you've probably seen them as well. Packed with Internet access, email capabilities, address books, and a whole lot more, cell phones have come a long way since their first debut. But be careful not to confuse these newest toys with sandbox devices.

Sandbox devices are tools that come pre-loaded with things like calendars, calculators, and a notepad. What differentiates them from smartphones is that users can add (download and install) additional programs to smartphones and they seemingly become mini portable computers for the people who use them. That - and the ability to edit the content that sits on them - is what makes these phones "smart."

Some of the more popular brand names include the Blackberry, PalmSource, Nokia, and Windows CE. Yet the craze is extending to even some off-brand company names. Today, it's hard to find a cell phone that doesn't offer some sort of "smart" technology because it's in such a high demand. The convenience of having information at our immediate access is phenomenal - so much so that thousands of programmers have jumped on the opportunity to build unique applications specific to these small machines.

As a result, you can find tons of games, databases, GPA systems, weather reporting programs, and even small encyclopedias on these things - each accessible not at the click of a mouse - but at a few presses of a free thumb. Of course a mini keyboard is available for the text-messaging fan or for the poor fellow who can't seem to get away from the office. In the latter case, don't be surprised if you find the entire Microsoft Office suite displayed within a screen no bigger than a matchbook.

Is this a phase? That's highly doubtful. The market for these devices extends from the highly technical and professional all the way to the pre-teen socialite. The product crosses all demographics and thanks to decreasing costs - it sees no economic boundaries as well. The Wikipedia encyclopedia claims that "Out of 1 billion camera phones to be shipped in 2008, Smartphones, the higher end of the market with full email support, will represent about 10% of the market or about 100 million units."

But what is it that makes smartphones so appealing? As mentioned, smartphones give us the ability to not only carry our data around with us where ever we go, it also gives us the ability to edit that data any place - any time. In today's "reality" based generation, we're always looking for the opportunity to capture and relive a moment. And we want to share that moment with others. At best, smart phones give us the opportunity to express ourselves impromptu with entertaining results.

Attempting to do the same with a bulky desktop computer or laptop is to cumbersome. Even some of the smallest peripherals (digicams, digital cameras, etc.) don't give us the same opportunities that smart phones do. Being able to carry around a device for communication, creation, recording, and editing simply compliments the need for today's generation to do more and then do it, faster!

Protecting Your Computer Is A Requirement

Advances in computer technology is a double-edged sword. On one hand, it affords us quick and easy access to numerous conveniences such as bank statements, favorite shopping centers, school and health records, and more. On the other hand, it can also grant the same access to those who aren't supposed to get it. Although it's a rare occurrence, hacking has become the biggest criminal nuisance in computer history.

Make no bones about it. There's nothing innocent or cute about the hacker. Today's hackers aren't the pimply-faced teen rebels that you might be thinking of. Instead, this generation of hackers are grown individuals who are more than likely earning a living by stealing the identities of innocent, law abiding individuals and then selling those identities to others who want to slip by the system. And the only protection against these seedy people is prevention.

Computer security couldn't be more important than it is today and that's why we've taken the time to introduce it to you. You can reduce the probability of experiencing identity theft by making your computer as hacker-proof as possible. All that's needed is a little software and a lot of common sense.

1. Install an anti-virus/anti-spyware program. Anti-virus/anti-spyware software will stop malicious code from downloading and installing onto your computer while you peruse the Internet. Known as viruses, worms, or spyware, this malicious code can destroy important files and render your computer good for only one thing: sending sensitive data back to the server of an identity thief.

2. Don't store sensitive data on your computer in the first place. Should your computer get infected with a virus, worm, or piece of spyware, you can thwart the individuals responsible by not storing your personal information on your PC so that when and if your computer does send back data - it won't be anything valuable. Hackers look for things like full names, social security numbers, phone numbers, home addresses, work-related information, and credit card numbers. If these things aren't saved onto a computer, there's nothing critical to worry about other than restoring your computer to a non-virus condition.

3. Don't open files without scanning them with an anti-virus/anti-spyware program. In the past, the warning was to avoid opening files from people that you don't know. Today it's really not safe to open files from anyone (without scanning the files) because that's how viruses get spread - through files - even by mistake. So even though your co-worker may have emailed a funny video, it's no more safe to open than a video downloaded from a complete stranger. Be safe and scan each and every file you download from the Internet or receive through email regardless of where it came from.

4. Create a barrier between your computer and prying eyes. Anti-virus/anti-spyware programs are only effective after the effect. But you can prevent identity theft from occurring by installing a firewall. A firewall is software that checks all data entering and exiting a computer and it then blocks that which doesn't meet specified security criteria (user-defined rules).1

5. Don't click on website links in spam messages. In an effort to obtain personal information, some spammers will send email that asks you to click on a link. The email messages are often disguised as important messages from well-known online establishments, and they often try to scare their readers into clicking links with threats of closing an account of some sort. Sometimes the links are harmless and attempt to con the reader into volunteering personal information (credit card number), but other times the links attempt to download harmful software onto a computer.

Your best protection against computer crimes is your own knowledge. Hopefully the suggestions above will prompt you into taking appropriate action and into protecting your computer with the suggested tools. In doing so, you'll not only protect yourself, you'll prevent the spread of these malicious activities and protect others at the same time.

Buying a New Computer? Read This First

Ever had one of those days when you thought that you would spend a lot of time searching around for really good computer bargains?

I have had that experience many times and have found that I used to waste time doing endless and meaningless searches trying to find what I need. But then, I found a solution!

Figuring out what to search for is half the battle won, but how to figure out whether the prices being displayed were bargain prices was another issue. So how did I solve that problem?

Try and identify first what computer system you need to buy. This really can be a struggle if you are not familiar with computers. You can visit the nearest library to you and speak to a librarian to see whether they have issues of the Computer Shopper magazine. Not only Computer Shopper, but PC Novice and PC Magazine as well. I have found these to be quite useful and effective in helping me decide on the type of system I need.

PC Novice is especially useful because it explains in layman's language what I need to know and gives recommendations on the alternatives to look for. Terms such as motherboard and peripherals are usually explained in detail. You should not worry however if you are not familiar with these terms. Just understand that when you go to purchase your computer, you may find an enthusiastic sales rep asking you – “so how much ram do you need in this computer”; “you think you may need an Intel or AMD processor?”; or, “how many gigabytes do you need for your hard drive? --- Huh???

The magazines I have listed above will help you a great deal but don't get lost with all the geek talk. You will be able to find complete systems available that will be sold with software. Some systems will be sold with the box – the CPU portion, and the monitor. Depending on where you are buying your computer from, the monitor may be at an extra cost. Some systems will be sold with a printer and they will try and sell you a host of other things which are not really necessary.

My advice therefore is to first figure out what you want to do with the computer and do some research!

Shopping around is the next best thing you can do to find the best prices. I usually look at three to four different quotations to see which one matches my budget. Most computers today will do what you want to do. You do not need to get the most expensive system especially if you will only be surfing the Internet and checking email occasionally, so don't go overboard thinking that because you saw you neighbor with this expensive system you need to have one too.

Be the Smart Online Casino Players

Some people are the regular casino players, but some others are just seasonal players. The seasonal players are players who are only playing during the vacation. Well, nowadays, I believe that the number of seasonal players is decreasing because all players can be regular players with the online casino. Bonus is one thing that becomes the magnet of why players become regular players.

Well, we must remember than online casino is just like a land based casino, it is a business industry. Therefore, make sure that players are not easily tempted by the amount of bonus. Playing on the online casino is so much fun and entertaining, but players should play smart. If we want to be smart players, make sure that we check the online casino tx bonus term and condition so we have good understanding on our right and obligation.

When we are looking for a perfect online casino, it will be better if we choose one from review like list of online roulette casinos, list of no download online casino, list of slot games online casino, and many others. If we are looking for an online casino independently and directly make a deposit, we will only risking our money and gaming satisfaction.
