Laptops, the new shape of technology
Laptops, the new shape of technology
by ken wilson
The moment we were offered the possibility to use desktops, we actually received a wonderful tool able to ease our lives from a multiple point of view. Computers lessen some of the tasks our work entails; they enable communication and also give us the opportunity to discover new ways to divert ourselves. However, computers themselves are subject to a continuous process of upgrading, and one of the many aspects regarding this process of improvement refers to portability. To buy laptop computers seems to be a better alternative to purchasing classic desktops from certain points of view.
Laptops, also referred to as notebook computers, are said not to be able to fully replace desktops. But to buy notebook computers may suit better some of our most imperative demands. Say you are an extremely busy person. Say you have to constantly keep track of certain events and that your job involves storing huge amounts of information that you need to use all the time. Laptops may be of real help. Regardless of the fact that computers in general stand for an excellent alternative of storing data, laptops in particular give you the opportunity to carry that amount of information wherever you need.
But this is not the only reason people buy laptop computers. It’s not just the job that motivates us to purchase such pieces of machinery. To buy notebook computers means to facilitate and to open new possibilities of spending leisure time. Surfing the Internet or watching a movie in other places than our rooms or offices boosts up the laptops’ reputation.
In addition, to buy laptop computers enables another possibility, namely, operating on battery power in case of an energy interruption. Energy outage, though not very common, may occur unexpectedly. Because we can not always predict such events, the consequences do not limit to diminishing the time we spend operating on the computer, which is also a source of other countless inconveniences. At the same time, we may lose precious files we work on when the outage occurs, in case we forgot to save them. However, problems do arise if such incidents happen. Notebooks work like a buffer in such situations.
Moreover, notebooks are popular for their energy efficiency. However high the energy consumption may be, it is still lower than if we choose to operate a desktop computer. Energy efficiency is not one of our main concerns when we decide to buy notebook computers. Yet, in certain circumstances, this may be an aspect we may need to carefully consider, and if energy efficiency is something we have to worry about, then choosing a laptop is the answer.
Another point we have to deal with regards a common preconception. Some people think that portability and the rest of upsides laptops genuinely prove are possible on the expense of the level of efficiency computers in general should demonstrate. Users familiar with regular desktops may be either pleasantly surprised that all the advantages computers offer are available in a more compact and appealing shape, or suspicious of all those. They may even be a little more cautious than necessary with respect to certain possible health issues. But there is actually no need to worry about all that.

Buying laptops online
by ken wilson
To buy laptop computers means to acquire an improved version of something that by itself represents a huge technological leap. Personal computers are so popular nowadays that most of our daily activities revolve around them. Both work and pastime rely on these wonderful tools, but since classic desktops have been exceeded in popularity by portable computers, more possibilities have been delivered to users around the world. But portability is not the only facet of the progress which technology is constantly subject to. An extremely important aspect concerns the purchasing in itself.
Online shopping is in general a perfected manner to acquire virtually everything. All sorts of products are available on online shops, from groceries and beauty care products to cameras, jewelry or plain tickets. With respect to computers, the way things have worked out seems pretty paradoxical, because in order to buy a desktop or a laptop online you need to make the request by operating a computer.
But why do people choose online shopping over the traditional way? Sitting comfortably at home, studying several offers displayed online without any additional pressure that sellers or manufacturers may put on you represent a good motivation. Above all, online shopping is obviously a more timesaving alternative. And if the quality of the products we buy and of the services performed for us has always been a topic of conversation, when it comes to online shopping the way we buy or we request those products or services becomes a subject of debate.
Therefore, to buy laptop computers online means to purchase in an improved manner an improved product. But what does this improvement refer to? On the one side, laptops are obviously designed to provide certain advantages that regular desktops do not. Portability, energy efficiency and the possibility to operate on battery power are some of the few valuable features that make people around the world choose laptops over desktops. On the other side, you may want to purchase a certain laptop technology that is not available in the town you live in. Or maybe you need some particular spare parts â€" we all know how this is an indisputable issue with respect to laptops. Or, again, perhaps you want to upgrade the laptop you already have. When it comes to such things, online shopping proves to be of real help.
Companies working online have the ability to display a more generous offer. They also put forward all sorts of buying guides and comparison tables that help the potential client make a better decision, that is, a decision that really fits his or her demands. Their official sites may even have testimonials or articles regarding the expectations of the year to come, that is, what will be the main tendencies, what manufacturer will sell better and so on.
On top of that, you have the possibility to take a better look at the product you intend to purchase because you benefit from web pages designed to put forward a comparison of the products fitting a single category, laptops included. So, you have the opportunity to exam prices, parameters of all sorts of compounds, life expectancy and the rest.

Have Laptop Will Travel -Great Way To Run a Home Business
Have Laptop Will Travel -Great Way To Run a Home Business
by Cindy Floyd
Don't let anyone tell you that your home based business is going to be easy and that all the work is going to be done for you. A home based business requires just as much effort as any other job you would take outside of your home. Dedication to your business requires same efforts you would give to a corporate career.
With one exception of course, all the efforts you give go to your benefit and not that of a large corporation. You really are the boss...I always wanted to be my own boss. So, you say you want to take off early today, go, no more dreaming up some excuse the big guy will buy just to get off to see your son or daughters sporting event.
In your own business you come first. For many people this is an ideal situation and a dream come true. Parents of young children can be there to help raise them, something I always dreamed of, or having the freedom to be there for an aging parent when they need you the most.
With an online business you can have all those benefits. Times have changed; this is not your old school network marketing anymore. If you have a computer you can work online. You can advertise you can make friends you can even have conference calls and training. Having a home based business no longer means house parties and harassing friends and neighbors.
I remember the first laptop my boss gave me. I was delighted to have the mobility it provided. What I didn't know was now I was expected to be in contact no matter where I was. It turned out to be my ball and chain.
However in my home business the laptop is my best friend. I can go anywhere in the world and work on my business. I can stay in contact by email and voice anywhere in the world. Isn't technology great? So now if I work on my vacations it's my choice and that extra effort really does show up in my pockets.
If you’re looking for freedom and a bigger pay check, look into a good laptop and a legitimate home based business opportunity. The personal rewards are inspiring.

Laptop Buying Guide
Laptop Buying Guide
by Bob Shanty
A laptop is the ideal replacement for your desktop computer. The greatest advantage of a laptop is its portability. Unlike desktop computers, you can easily move a laptop around your home, carry it to work or class and take it with you when you travel. Laptops are a big investment, so before buying one, you should consider many factors like the manufacturer, performance and features.
What kind of laptop user are you?
A home user wants all the features of a desktop PC in the form of a notebook. If you are a home user, then choose a notebook which is easy to carry and comes with the most basic computer applications. Students should opt for an affordable laptop which is light and durable. Frequent fliers need slim notebook models with long-lasting batteries. A business user should purchase a laptop with plenty of hard disk space and advanced security features while a gamer needs a fast processor and the latest graphics card.
What are the different kinds of laptop computers available?
Laptops for Entertainment:
Multimedia laptops are always more expensive and heavier than your standard model. These laptops come with a powerful processor, abundant memory and a large hard drive. You can use these laptops as a mobile DVD player, MP3 jukebox and a digital photo album. If you buy a TV tuner card, you can even use your multimedia notebook as a television set. These notebooks are ideal for PC gaming.
Laptops for Business:
Laptops especially designed for business use are ultra portable. These laptops are durable and more secure than the basic laptop. They are best suited for consumers who are always on the move. A good business laptop should offer a fingerprint reader or SmartCard support to prevent data theft. These notebooks usually have advanced computer applications and wireless capabilities, so you can work even when you are away from your desk.
Laptops for Home:
The home user typically uses a laptop for checking mail and browsing the web. These laptops perform general tasks. A high speed processor is an unnecessary luxury and tends to be wasted on most home users. Opt for a notebook with at least a 14-inch screen and a comfortable keyboard. These laptops are generally heavy, weighing more than 4 kg at times. Their average battery life is less than three hours.
What constitutes a good laptop?
Ergonomics:
If you are going to use your laptop extensively, then you need to be comfortable with the keys. Try a laptop with slightly larger keys to avoid straining your fingers from typing. Most laptops come with a touch pad or a tracking pointer instead of a mouse. If you are a PC gamer, buy a separate mouse which can keep up with the fast-paced action on screen.
Operating Systems:
The Windows XP Media Center Edition is a good operating system for entertainment laptops. It makes optimal use of multimedia features like TV tuners, radio tuners and media players. If you are a professional who prefers Apple notebooks but are concerned about compatibility, check out the dual boot models by Apple that allow you to install and run Windows as well as Mac OS X. If you prefer PCs, Microsoft Vista is an ideal alternative to Windows XP. Vista comes in several editions, including Vista Home Basic and Vista Home Premium for the home user, Vista Business for the professional and Vista Ultimate for the best of both worlds.
Memory and Storage:
All data and applications are stored in the RAM (random access memory). Many laptops commonly use 256 MB of RAM. Most business laptops and entertainment laptops come with 512 MB or more of RAM. The more RAM you buy, the more data you can store.
The hard drive stores all programs and files. For the average home user, a 20 GB hard drive will more than suffice. If you buy a laptop for entertainment or business purposes, a 60 GB hard drive will better serve your needs. Some entertainment laptops even have multiple hard drives for better performance. Hard drives come with different speeds. Most laptop hard drives have a speed of 5,400 rpm. However, faster hard drives go up to 7,200 rpm.
Display:
The size of a laptop is based on the size of the screen. Screen size starts as small as 10.6 inches and goes up to 20 inches diagonally. Most laptops have an LCD monitor. However, if you are using your laptop for CAD, a CRT monitor will serve you just as well, if not better. The screen resolution determines the crispness of your image. A 12.1 inch display uses WXGA resolutions (1,280 by 800). A 14 or 15 inch display typically uses WSXGA+ (1680 by 1,050), although a small number of notebook computers use WUXGA (1,920 by 1,200) instead.
Processor:
It is more difficult to upgrade a notebooks processor than it is to upgrade a desktop computer. For this reason, you should buy a processor with a speed that will best suit your use. Also, it is wise to choose a processor with less battery consumption. Processors with 1.4 to 1.6 Ghz are preferred by most users.
Battery:
Lithium ion batteries are commonly used in laptops. The average battery life is about 3 hours. It takes around 75 minutes to fully recharge a lithium ion battery.
Graphics Card:
A graphics card, sometimes referred to as a video adapter, is responsible for generating the images you see on a laptops display. For businessmen who need to do lot of presentations, a graphics card containing 32 or 64 MB of dedicated memory is the right choice. There are also specially designed cards for gaming. These cards are expensive and should be avoided unless you require excellent graphics.
USB Ports:
Laptop computers come with at least one USB port so that you can connect peripherals to the notebook. Recent models have a FireWire connection that lets you transfer digital information from camcorders or MP3 players.
Optical Drives:
Most laptops come with either a CD-ROM (compact disc, read-only memory), a CD-RW (compact disc, re-writeable) or a DVD-ROM (digital versatile disc, read-only-memory). The DVD+RW/+R with CD-RW is a combination drive which will read a CD or a DVD and write data to a DVD as well.
Modem:
Laptops are available with integrated modems for dial-up connections, Ethernet ports for cable internet and DSL and wireless modems for Wi-Fi connections. Many business laptops also have a cellular wireless modem so you can browse at broadband speeds with just a mobile phone signal.
