Finding a Cell Phone Holder

February 10th, 2010

Shopping for a cell phone holder seems simple enough, but it can be complicated by unlimited choices. A holder could be a phone case or cradle, the possibilities are endless, spanning from unique novelty cases to a vehicle installed cell charger. Especially with blue tooth, the most common are car kits which I will focus on. Consider these 5 points before you buy. Don’t worry-no technical expertise required. Here are some common options to help select the right one for you.

Universal or Specific? There are holders designed for certain brands or specific models. One of the most important differences is whether you have a PDA or cell phone. This-along with size–is the only distinction that really matters when looking for a universal holder. Universal holders are inexpensive (as low as $10) and have a suction or adhesive mount for any vehicle. They are padded inside to secure a wide range of devices.

Passive or Active- This was confusing to me. I hadn’t heard these terms used to describe a cell phone holder or cradle. Moreover, it was difficult to find their meaning; definitions weren’t readily available on product sites. Eventually, I found it refers to charge. In a nutshell, active will charge the phone while in the cradle, while passive won’t. Although, you can plug a travel charger cable into your phone while it’s on the passive holder. Fixed is installing the active cradle to connect to the vehicle’s electrical system.

Installation- Installation is simple with windshield or dash suction mounts. Adhesive discs are also common and can be placed anywhere. Another solution is a mounting platform like Proclip. The clips to dashboard seams for permanent and secure attachment. A screwdriver is needed but not to screw it to the car-no damage is done. If you’re going for the gold, and want the electrical connection, leave it to a professional.

Mount place and phone size- Mount on the vent, dashboard, windshield, console and cigarette lighter. It’s easier to find cigarette lighter mounts for small phones, keep the bigger models on the dash.

Cost & Extras- Basic (passive) cradles can be less than $10, before shipping of course. Even these have the convenient tilt and swivel option for screen visibility. The price goes up based on features, i.e. a charger for your bluetooth headset or a dual holder for GPS. Some have a USB port for data syncing and charging.

Hopefully, these points have given you a place to start. Now, with an idea of what’s out there, you’re ready to go. Happy hunting!

Common Problems With XBox 360 and Laptops

January 10th, 2010

Any electronic device will get hot and can freeze while working. One can imagine playing a favorite game on Xbox 360 and the mission was almost about to finish when it suddenly freezes and nothing would move. Laptops generate heat just like any electronic device, they already have a cooling system in place and the cooling system is also small because of their small size. It is sometimes insufficient in cooling down the laptop’s processor. A laptop’s bottom can get hot to such an extent that it can burn one’s skin. One wonders why does this happen.

Just like a laptop, an Xbox 360 is also infamous for overheating due to a somewhat inefficient heat removal system. Using it for lengthy periods can cause an Xbox to freeze and overheat; the only solution for this is to power off the console for an hour or so until it cools down. For preventing overheat, the console should be placed in an area which has plenty of air flow and where the console is raised off the ground.

If a laptop gets hot very quickly, the reasons can be blocked air vent, fan not working, too much dirt, may be the battery or the brand. The laptop’s fan and other cooling components are very important to the overall operation of the laptop. If the fan stops working and there is not enough ventilation, the computer will get quickly so hot so that it will even crack the LCD screen.

Too much dirt inside the laptop can damage it. The dirt can block the air flow inside and the processor may not be getting enough cool air. The laptop has to be shut down and the laptop needs an inside cleaning. A laptop’s battery overheating can cause fires. If the battery gets hot, it can even explode so it immediately has to be replaced. A laptop’s brand may be sometimes the reason for the overheating. There are a few laptop brands that are sold to the lower-end market. Quality could have been compromised to keep the manufacturing cost low which will also keep the retail prices low. Selecting the right brand by understanding each laptop brand’s specifications is the right solution.

Microsoft is aware of the freezing problem with Xbox and is happy to exchange a defective one with a new unit complete with shipping and delivery costs. Same problem can still happen if Xbox 360 is operated without care. One must make sure not to use it for long periods without a way for the console to release the heat. It should be placed where there is constant air flow and it should be plugged into a power source with a constant flow of electricity.

Since a user knows that a laptop tends to overheat, it should not be kept running for a long time. If it needs to be used, it should be placed on a table which allows air flow through its vent at the bottom. Another option is to buy a cooling pad that will keep the processor’s engine down to a minimum level. It is important to keep the temperature low to prevent burn out.

Computer Networking – Elements and Components

January 1st, 2010

When studying computer networks, one must consider the main elements that will compromise the computer network. The main elements that must be considered will be presented below:

1. Message: the message is a generic term that scribes the data to be transmitted. It can be email, webpage, user call, instant message, or any other forms. The message is generated by the end user that needs to make the transmission. This message will be fed to the network later.

Generally, the message is generated using software installed on computer. For example, if the message is email, it will be generated by email programs such as outlook. Also if the message is a web page request, it will be generated by a browser such as internet explorer. It can also be generated by a chatting program is it represents a call by the user.

2. Medium: the medium is the transmission path over which the data will be transmitted. Is is used to connect the end user with the network device or to connect the network devices with each other.

Many types exist for the medium. Mainly it can be wired or wireless medium. The wired medium can be copper or optical fibers. The copper is subdivided into coaxial cables and twisted pairs. The copper wires carry data as electrical pulses while the optical fiber carry data as light pulses. The wireless medium carries data as electromagnetic waves. Each of the above mediums has its own specifications and used according to the application.

3. Devices: there are two basic types of devices in the network: end user devices and network devices. The end user device is considered to be the source of the message. It can be a client computer or an IP phone. The function of the end user device is to send the data to the network.

On the other hand, the network devices are used along with the medium to forward the data generated by the end user device. They are located in between the end user devices and connected between them through the cables.

The main function of the computer network devices is to forward the data to the correct destination based on the address that is send along with the data. The two main devices that accomplish this are the routers and the switches. The router forwards the data according to the IP address while the switch forwards the data according to the MAC address inside the data frame.

4. Rules: the rules are the protocols that used between the end user devices that organize the communication. The two popular protocols are the IP protocol and the TCP protocol. When the end user needs to send the data, it runs a conversation first with the other device according to a set of rules that prepares for the transmission. Each network uses its own protocols set up by the administrator of the network to manage the operations inside the network. Note that this element is a software element and is set up by software programs

Dual Monitor

December 20th, 2009

Computers today have become inherently cheaper for most people because we are living in an extremely digital world. Moreover, they are more affordable these days because computer monitors are becoming cheaper as well. This also includes the video hardware that drives the computer unit as a whole.

Getting the right kind of dual monitor that works correctly seems to be quite difficult. Most of the time, It is just a matter of incorporating another separate video card monitor and rebooting the computer to make it work. Sometimes, there will be a need to incorporate other means such as cyber modifications to operate them effectively and get computer tasks done more efficiently.

The method being applied is pretty much the same regardless of the version of Windows being used. First and for most, it is necessary to make sure that the system you are using is working correctly. Afterwards, you can boot the computer into a safe mode and correctly approve of whether you only use one video adapter and the Device Manager that is being showed by the monitor. If there are more than one video adapter being used, It is necessary to exclude all the extras.

Other people can have one of those computers having two screens in one computer unit. This is commonly seen in places where loads of office work is done. It is no surprise that those with busy lifestyles consider thinking about having these as well. Basically, there are two screens that you can incorporate into one computer unit. One of the factors that you have to consider to be able to make this possible is to have a monitor video card. This card will tell your computer unit that there will be a need of two computer screens instead of just one. This type of set up will never be made possible without the dual monitor video card’s help.

One of the things that you need to inspect is the computer’s vacant slot that will enable these video cards to be installed. This is depended upon how old your computer is. Generally, newer versions of these units have more slots available. The internet has loads of information that you can check out to see what these available slots are like. You can even refer to your computer manual to see the attributes your computer unit possesses that you can take advantage of. If the manual does not contain the information you need, it will be inconvenient for you knowing you have to spend a lot of money trying to fit this to your computer for it to function properly.

It is more advisable to have a new computer unit with the latest version. You can pick ones that have extra slots for dual monitor video cards. This alternative is becoming more and more popular and some business firms that are all about manufacturing computers are making this as a new standard so it is necessary to read and make some verifications of fine print and do some assessments. Sometimes, there will be a slot available for a card but there will be a need to buy a card after purchasing your computer unit. These are available at any electronics or computer stores needless to say, online, as well.

Desktop PCs Available in Many Models

October 20th, 2009

If you are ready to purchase a new desktop PCs, start your shopping armed with a list of non-negotiable features. These are the things you cannot get along without. For example, if you want to run more than one program at a time, a dual core processor.

Most new computers include a one year warranty. An extended warranty for two or three year coverage might cost up to $200. Ask what it covers, such as in home repair, all parts or online technical advice. It may be worth the money if you are an inexperienced PC owner.

If you are unsure about adding extra memory or RAM (random access memory), keep in mind that adding it later on when you wish you had it, is much more costly than if it’s factory installed. If you store video or tons of pictures, you may need extra storage capacity.

will you be using the PC for running a home business? Then you will want to upgrade to the professional level Microsoft Office Small Business Edition. You can find a bargain if you will be using it for email, browsing and making family photo albums. Should you be a gamer, dig deep for a quad processor and all the other high end features required at a much higher cost.

Check to find USB ports that are conveniently located on the front of the PC so you can plug and unplug as needed. Decide how many extra USB ports you might need later on and be sure they are on the model you buy. If you plan on manually adding to the system at a later time, look for easy access to the hard drive.

Select a motherboard with an open graphics slot in addition to the ones installed at the factory. A dual core processor is adequate unless you are a gamer. Then you will be interested in a quad system. The price for such a system is considerably higher.

If you are at the store that has the desktop PC with all the features you need, you might be tempted to wait for a sale. That is a great idea, unless there is any possibility of a sell-out on your chosen model. If there is, take it home with you today.
