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.

4 Great Advantages Of Having A Rack Mount Computer
1. Really provides better cooling for your computer hardware
We all know that heat can really kill the motherboard, processor and other chips that are found in a computer case. If the temperature is too much it can fry the chips and leave your computer worthless. The more work you do, the longer you do it, the higher the workload on the pc. This causes heat to build up inside your computer. The traditional cooling fan that you can find on the back of the power supply of your computer is normally not enough to get it all the cooling it needs. Even with the other fan attached to the processor chip, your computer will most of the time not get all the cooling it needs.
If you were to use a rack, this would help to give your computer the cooling it needs, since it gives you a lot more space, unlike computers that don’t have racks.
2. You’ll have better air circulation
Without adequate space for your computer, there won't be good air circulation and this can damage many things in your computer. A rack mount computer therefore gets better air circulation than one without it. And this goes a long way in protecting your computer.
3. Prevents vibration when playing load music
Good computer racks out there have vibration-dampening tendencies to prevent the vibration of your computer- especially when listening to load music from your speakers. Without these vibration-dampening tendencies, your speakers and even compute can slowly slip off your desktop, thereby causing damage.
4. Give more space for your computer
Your rack mount computer has more space than others without one. You are able to do more work than if you didn't have a rack for your computer.
If you take all the above advantages into consideration you will come to find that using a rack mount computer instead of one without a rack is the way to go.

8 Things You Must Know Before Building A PC
Perhaps you're interested in learning how to build your own computer. That's great, really!
I've put together a list of 8 things you MUST know before you ever start to build your own PC. You'll be in a world of hurt if you don't have these down.
Tip #1 – Safety First
I hope you didn’t think the last time you’d hear “safety first” was in your Drivers Education classes! Working on any electronics, including computers, has its risks and requires certain precautions. Having said that, what’s the first part you should purchase when building your own computer?
* Motherboard?
* Processor?
* Computer Case?
Nope, those are all wrong. And honestly, they aren’t even close!
A computer tool kit should be the first thing you purchase. Normal household tools aren’t suited to working on a computer because they’re often dirty, rusty, and magnetic. Here are some things you must have in your computer tool kit :
Antistatic wrist band – This is a must-have for any computer builder. Your computer's components are very sensitive to static electricity. Make sure that you ALWAYS have your antistatic wrist band on when working on your computer. You must attach it to a ground source, usually a large piece of metal works well. This removes any free electrons, which cause static charge, from your body to the ground. Also, as an additional measure, before touching any hardware, touch your computers metal frame. This will also help put your body’s charge at equilibrium with your PC’s.
Needle-nose pliers and Tweezers - These tools are useful when handling small screws and bits of metal. Your computer's circuitry is very precise and you'll need some good tweezers and pliers to hold things into place.
Screwdrivers – This is an obvious requirement for computer tool kits. You should have at least one small Phillips and Flathead screwdriver in your kit.
Spare parts container - You'll be surprised how handy one of these will be. They can be used to store small parts, screws, spacers, etc.
Nut drivers - Although these aren't a requirement for your tool kit, most tool kits come with some nut drivers. I have yet to use mine, but someday I'll probably need them.
Small flash light - Most computer tool kits don't come with a small flashlight, but it is a good thing to have when you’re working in a dark computer case. A keychain type flashlight works great for this purpose!
Also, make sure all of your tools are NOT magnetic. Many screwdrivers for small screws are magnetic to help hold the screw in place. You don’t want this when dealing with your computer hardware because the magnetic field could damage your components.
I can’t stress this enough; having the correct tools is the easiest way to avoid damaging your components that could easily cost you hundreds of dollars. And please turn off and UNPLUG your computer before working on it, the last thing you need is a phobia of computers after you’ve been inadvertently shocked by one.
Tip #2 - Buy everything at once
This is was a major mistake that I made as a rookie computer builder. I know how anxious you may be to build your first computer; I can still remember how excited I was when UPS delivered my first part. But before you start buying parts left & right, you should set down and answer the following questions:
* What do I want to do with my computer?
Simple internet browsing? Word processing? Graphic design? Audio and video editing? Play video games?
* How long do I want this computer to last me?
Only for a couple years. Forever!
The idea here is to decide where your money will be best spent to maximize the use and/or life of your computer parts. For long term and/or intensive use, such as video/image editing, you’ll want something that you can easily upgrade over time. While for short term and/or simpler tasks, a cheaper, less upgradeable PC should work fine.
The easiest way to assure that all of your computer components will be compatible is to purchase them all at the same time. This way you can compare the features and requirements all at once.
I recommend that you start with your motherboard and processor. Many companies sell motherboard & processor bundles . A bundle is great way to start buying your computer parts because usually you’ll get a deal when you buy the processor and motherboard together. In addition, the processor will be compatible in that particular motherboard, which is one less thing you’ll have to worry about.
Next, select the type of RAM that is compatible with your motherboard and decide how many MB’s of power you want with it. Generally 512 MB of RAM will be sufficient. If you plan on doing image/video editing, or playing video games on your PC, 1 GB of RAM would be better suited for this job.
Now you can decide what types of extra components you want, such as a video card, hard drives, CD/DVD drives, etc.
Once you’ve picked those out, determine roughly how much wattage of power you’ll need from your power supply . I’ve attached a power usage chart below with how much each component uses, but these are only averages, so I can’t guarantee this is what you’ll observe.
Device [Power required (Watts)]
Video card [20 - 30]
PCI card [5]
Floppy Drive [5]
CD, DVD-ROM [10-25]
RAM per 128 MB [8]
Hard Drive [15-35]
Motherboard [20-30]
CPU [25-70]
Generally 400 watts should be plenty of power, even for the most power hungry systems you can build. Also consider purchasing a quiet power supply, because the power supply is generally your noisiest piece of hardware. I personally use a 400 Watt Zalman Quiet Power Supply (pictured at left) that I love. It provides tons of power with virtually no sound.
By purchasing everything at once you can ascertain that your computer parts will support all of your computing needs. Another benefit is that you’ll save money on shipping charges by purchasing everything at once rather than separately.

5 Reasons For Owning A USB Flash Drive
There have been a number of wonderful inventions during the 20th and 21st century. Some of these creations have been both massive and minute. Very few of mankinds modern creations have revolutionized working life so much as the USB flash drive though. Ok now that might seem a bit much for some people but the reality remains the same - USB flash drives have made the working lives of millions of office workers, teachers, students, IT and other professionals massively more simple. If you already one (or a few) USB flash drives then you'll know just how incredibly useful they are. If you don't already own at least one USB memory stick then hopefully this article will help convince you of their absolute usefulness in both your working and personal life.
So what's so great about USB flash drives?
Small
Prior to the creation of USB flash drives all external storage devices for computers were either bulky or awkward (dozens of blank discs for example) or sometimes an annoying combination of being both bulky and awkward. USB flash drives are also called Thumb Drives because they're about the size of your thumb (although some are much smaller now) and you can easily fit several gigabytes of data in your jeans or shirt pocket thus eliminating the bulky and awkward factor straight away.
Portable
USB flash drives are about the single most portable data backup device possible. They don't require an external power source of any kind, nor do you need any cables or tools to set them up and last but not least they don't require any additional software to be installed for them to work on any modern computer (Windows XP, 2000 and Vista and most Macs) so you can quite literally pick them up and use them anywhere you want.
Reliable
Once the data is stored on a USB flash drive you can rest assured that it's going to stay there and be there when you next need it. This is totally unlike the world of floppy disks or rewriteable CD/DVD discs where they can just stop working for no apparent reason. Flash drives were built to provide consistent and reliable performance. Most of these drives come with built-in write protection to prevent you from overwriting your own important data - if you were silly enough to do so.
Tough
For years people fiddled with boxes of floppy disks and CDs/DVDs. These were bulky, easily lost and easily damaged. External hard drives also provided another method of transporting data between systems but the smallest jolt was and is enough to kill an external hard disk stone dead. USB flash drives are based on what's called Solid State Memory - this simply means that it's the same as standard computer memory in that it has no moving parts and is therefore almost impossible to damage (except for jumping up and down on it or maybe hitting it with a hammer for example. Please don't test either of these theories at home!)
Mass Storage
The first USB thumb drives only offered between 16MB and 64MB of storage space. The incredible popularity of these drives has driven the desire for more and more storage space to new heights every few months. Currently 8GB USB drives are becoming pretty common and it won't be long before the 12GB and 24GB models hit the market. To put this in perspective 8GB is enough to hold 2 full DVD quality movies or about 2,700 high quality MP3 files - surely this is enough for you? No?
The portability of the USB flash drive combined with reliability and the more than generous storage provided by such a tiny device make them the smart choice for anyone who needs to move files between PCs or simply just keep a second copy of their most precious data on a secure and reliable storage device.

Computer Training School Tutorial: Know Your Instructor
Making the decision to attend a computer tech school can be one of the best decisions of your life. Another great decision is to tap a hidden wealth of knowledge that is right before every student at schools such as ECPI and ITT, but very few students take advantage of it.
When you're attending a computer training school, you must avoid the mentality that some other students will have - "I gotta go to school, I gotta be here, I can't wait to leave and go home". When you're preparing for a career working with computers, you've got to take advantage of every learning experience you can get, and that includes getting to know the most valuable resource at your school - your teachers!
Your teachers have busy schedules, but it was my experience that every single time I asked for help or had questions outside of class, my teachers went the extra mile to help me. I’m sure yours will do the same for you, but you have to let them know you want that help!
At your tech school, you must develop the skills and work ethic that you will use to succeed in the IT field. By staying after class, working overtime in the computer labs, and getting to know your instructors, you'll be astonished at the additional knowledge you can pick up. Almost any good teacher is going to have real-world experience, and you need to draw on that knowledge. Having lunch with an instructor is another great idea, as it allows you to get to know them away from the classroom.
Part of success in any field is making contacts for the future. You may not be in the IT field yet, but you should already be getting to know people with IT experience - and who better than your teachers? Besides, they hear about job openings all the time from friends, and the more you stand out from the crowd, the more likely you are to be remembered for such opportunities!

Cisco CCNA Exam Tutorial: Loopback Interfaces
As a CCNA candidate, you most likely have some background in PC hardware and workstation support. If so, you're already familiar with loopback interfaces, particularly 127.0.0.1, the loopback address assigned to a PC.
When you're learning all about the different physical interfaces for your CCNA exam - serial, ethernet, and BRI, among others - there's one logical interface you need to know about, and that is - you guessed it! - the loopback interface.
What isn't as immediately apparent is why we use loopback interfaces on routers and switches to begin with. Many of the Cisco router features that can use loopbacks are intermediate and advanced features that you'll learn about in your CCNP and CCIE studies, but these features all come back to one basic concept: If the loopback interface on a router is down, that means the router is unavailable as a whole.
In contrast, a physical interface being down does not mean the router itself is out of commission. A router's ethernet port can go down, but the other physical interfaces on that router are still operational. Since a loopback interface is logical, there's nothing physical that can go wrong with it.
As I mentioned, you'll learn different Cisco router and switch features that utilize loopback interfaces as you climb the Cisco certification ladder. There's one misconception about Cisco loopback interfaces that you want to get clear on now, though. You’re probably familiar with loopback interfaces on a PC, and may even know that the address range 127.0.0.0 is reserved for loopback addressing.
Note that this reserved address range does not apply to loopbacks on Cisco devices, however. If you attempt to assign an address from this range to a Cisco loopback interface, you get this result:
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#interface loopback0
R1(config-if)#ip address 127.0.0.2 255.255.255.0
Not a valid host address - 127.0.0.2
R1(config-if)#ip address 127.1.1.1 255.255.255.0
Not a valid host address - 127.1.1.1
The range 127.0.0.0 is reserved for host loopbacks (such as PCs), not routers or switches. The most commonly used address from this range is 127.0.0.1 – if you can’t ping that on a workstation, that means you can’t ping yourself, which means there’s a problem with the TCP/IP install itself.
Keep these details in mind on the exam and in the workplace, and you’re on your way to CCNA exam success!
