Laptop Computers

A laptop is a personal computer which is portable. It may also be known as a notebook. The typical laptop will range in weight from 1 to 3 kilograms, and will generally have an internal battery as well as a power adapter. While most laptops are portable, few can currently match the power of the most expensive desktops, though this will likely change as technology continues to advance. The word laptop was first introduced in 1983, and was used to refer to the Gavilan SC.

Despite the name, most laptops should not be placed in your lap if it is not covered, because they can get hot, and can even burn skin that is held against it for extended periods of time. The typical laptop can be powered by one battery, and the power adapter can power the battery when it is plugged into a wall outlet. A laptop can perform many of the same tasks as a PC, but they tend to be limited. They will have the same internal devices which are seen in desktops, but they will be much smaller in size. Most laptops will have a screen which uses a liquid crystal display.

Most manufacturers have designed their laptops to work with a keyboard and mouse, and they will also have a touch pad that can be used to move around the cursor on the screen. Laptops come in three varieties, and these are based on the size. An ultraportable laptop will generally weigh less than 1.7 kilograms, while a thin and light laptop will weigh up to 2.8 kilograms, and a medium sized laptop will weigh up to 3.5 kilograms. The idea for the laptop existed prior to the invention of the personal computer, and was first conceived during the 1970s. The very first laptop was the Osborne 1, and it was released in 1981.

While the Osborne 1 was massive in comparison to contemporary laptops, it was revolutionary for its time, because it allowed people to carry their data with them, and the computer didn’t have to be left in a single location. However, the Osborne 1 was so large that it was not possible to run it on a battery. Most laptops today now use lithium ion batteries. While laptops have a few advantages over their desktop counterparts, they have some disadvantages as well. Unlike desktops, they are limited in their ability to be upgraded. As of this writing, their is no form factor for laptops, and the costs and technical issues involved with making them easy to upgrade aren’t feasible.

The only parts of most laptops that can easily be upgraded are the hard drive and RAM. In addition to this, laptops are expensive to repair if they are damaged, and they are also easy to steal due to their small size. Stolen laptops are a common cause for identity theft. While the use of the USB port has allowed laptops to be upgraded to some degree, it will typically reduce their portability. Historically, the performance of laptops has always been low when they were compared to desktops in the same price range.

The Latest Technology, Wifi And Digital Cameras

We were all use to the idea of sending in our film for developing and waiting for our pictures to come back. It takes days before we can see those developed photos.

Then along came digital cameras and the world was taken by storm with this cool new technology. Suddenly you could take a picture and see the results immediately. At first these cameras were slow and not such great quality but still kind of cool. Then things heated up and now we have fantastic digital cameras of all sizes and shapes that can take wonderful images which can be shared instantly with your family, or the rest of the world for that matter.

The latest now in technology integration is WiFi and digital cameras. No need to even plug your camera memory card into a computer, or a printer at all. Now you can buy a digital camera that transmits the images via wireless technology. Yes, that is right, a wireless connection for your image uploads.

Now, you may be among those in the population that have not even gotten their hands around the whole digital image sharing thing yet. But this promising new technology may lead us to a world of fewer cables to plug in, quicker transfer of our images, and in the case of events in the world, the ability to share images of news almost instantly.

As we saw in the recent bombings in London, folks with cell phone cameras recorded the devastation they saw in the underground and shared it with the world in almost real time fashion. These new cameras may be able to take that sort of thing to an all new level. Imagine cities that implement widespread WiFi access and photographers with WiFi cameras capturing images of news and other special events. They could transmit those images right away and let the world see them. You may concern how it works? Here is am eaxmaple:

Nikon has released two models of digital cameras that are WiFi enabled. The idea is to be able to transmit your pictures straight from the camera to your computer or printer through a wireless adaptor. You bring up the images to transfer, hit “go”, and they get sent through the air to your printer. The Coolpix P1 and P2 will be in the $400-$550 range in pricing and the adaptor is extra. They are competing with Kodak which released its own version of the WiFi camera in their Easy Share line of cameras this year. Kodak has already gone to making it easy to share photos by transmitting them at so called “wireless hot spots”, usually cafes or stores where wireless access is sold or given away to customers. These efforts by the leading camera makers seem aimed at adding value to their already impressive digital technology.

Digital cameras continue to be hot sellers despite what some in the industry thought would be a slowing of sales this year. Many had predicted that cell phone cameras would slow digital camera sales, but this is not happening.

Shopping Wiser for Electronics

It was common observation that people mass forward to their nearest electronics shop the very day after Thanksgiving to buy their early Christmas wares and gifts. That date has been pegged by many businessmen as one of the unbearable cart traffic days of the entire year, if it’s not already the most unbearable. And after the long holiday period, it is expected that some opportunists who are looking for nice bargains trek and dole out some cash that should have been spent during the December days.

This is not the case in today’s time. Store owners are now wise to sweep their holiday inventory, opening their establishments in the following year with products that might not already be on the customers’ “to buy” lists. That is due to the use of the latest supply management software. Supply management software monitors demand and the products kept in the supply room daily. The management calls for shipment when it is needed.

The effect is on the price of the products. Price cuts now occur seldom and sporadically, and it is now impossible to hunt for the newest sale items since there’s nothing left in the racks to put on markdown. The inventory is kept lean until the latest gadgets and gizmos are introduced. Before, home electronics that didn’t make it to people’s wish lists last holiday will be up for sale come next year. Now, an average customer who is not much into the latest electronics will be surprised that a flat screen t.v. he’s been dreaming to buy after Christmas is still normally priced.

For the hard-core intelligent shopper, there is some way to go around this emerging trend. First, you have to know that the peak buying season usually happens at the start of spring. It would also be nice to avoid impulsive buying. Always look for latest news on the release date of novel products and what stores are offering the best bargains. And it would also be helpful too to look at the market performance of gadgets since some electronic products do not enjoy a
healthy market demand. That means that a price drop may be in the offering soon.

Making Life Simple With Wireless Technology

Wireless fidelity , or WiFi, is an amazing technology that allows you to network your computers, office, home, etc. without the need for wires. This makes networking so much easier and less messy because wires are not used. The computers simply connect to the network via radio signals.

Because of this easiness, many businesses, schools, malls, restaurants, cafes, stores, airports and other businesses have set up wireless hot spots that allow anyone to log onto the network. This is amazing for individuals that need to be able to work from any location, however there are some disadvantages because hot spots can be used by unauthorized users if not adequately protected through different security safeguards.

Hot spots are relatively new, but are growing in acceptance and popularity because of the incredible access it gives to students, travelers, business people and the like. Some hot spots are free, while others charge an hourly rate.

These days, if you go to an airport or hotel you will see signs that say internet zone or hotspot and will either say free or how to pay. Because of this evolution, individuals are able to work and study wherever they are, which makes traveling and working much easier and less downtime which is very important.

Wireless networking can also be installed in your home, which means you can work in any room in your home or even outside if you so choose. Many individuals are starting to realize how much easier this makes their lives and are installing the equipment necessary for a wireless network.

To get started, you will need an Internet connection, a router, and then wireless cards for your respective computers. The router allows the Internet signal to be routed throughout the home and the wireless cards that each computer has picks up the signal which eliminates the use of wires. All of this equipment can be purchased in your local computer store or online if you are looking for extra discounts.

If you are interested in installing a wireless network in your home, office, or business, then you can do some research online and install it yourself if you know even a little bit about computers. However, if you have a lot of computers you want to connect or are unsure of what you are doing, then you might consider hiring a professional to handle your wireless solution for you.

Once you have the wireless network setup anyone in your “hotspot” will be able to log onto the server as long as they are within range. However, if you want to exclude just anyone from logging on then you can use a virtual private network, Internet Protocol Security, or other security programs that will protect unauthorized users from logging onto your network.

Bluetooth Technology Is Likely To Be The Answer You Are Looking For!

Several large and well-known companies developed Bluetooth as an industry standard. The standard was introduced in order to specify how hand held devices, computers and other peripherals would communicate with one another without the need for cables. It uses short distance radio signals in order to generate communication between one device and another in close proximity. It is already widely used around the world in particular in bluetooth headsets, used for speaking on your cell phone when driving. However, data can be passed between any bluetooth devices within range.

Bluetooth is the simplest and most widely available technology of its kind. This means that manufacturers can build bluetooth-enabled devices quickly and effectively and pass this saving directly on to consumers. It is also extremely convenient and bluetooth devices are usually incredibly small. This is why it is used in hands free headsets for use with cell phones.

Because bluetooth is the industry standard, this means that it is widely accepted and regularly used by companies from all over the world for many different reasons. Because it is so easily accessible and the transfer of data from one bluetooth device to another is completely free it is the most popular option. It is also incredibly easy for consumers to use and in many cases it is simply a case of turning the bluetooth devices on and then sending the data as required.

Due to 128-bit encryption and adaptive frequency hopping, bluetooth is a secure method of transporting data over short distances. Whether you want to transfer files from your notebook to your computer or you want to talk on your cell phone while you are driving, bluetooth technology is likely to be the answer you are looking for. Businesses and individuals all around the world, use bluetooth on a regular basis.

Are We In A Golden Age Of Electronics?

What defines a golden age? Conventional wisdom echoes that a golden age is when the quality of the product being produced is at its highest level possible; When every new innovation or release is equal to or superior to the standards of excellence that have already been achieved. It is nearly impossible to determine when you are experiencing a golden age until many years after is has passed – rarely can you identify a golden age while it is taking place. And there are some well-noted golden ages: the golden age of television, radio and movies being the most identifiable; all arts that are based upon creativity and public distraction.

When it comes to electronics, anyone can surmise that the quality that is being released is far superior to anything that has ever been created before. High-definition televisions are becoming even higher defined. Video game systems, such as the Playstation or the Xbox 360 are taking the gaming diversion from pastime to exhilaration. The broadcasting of music is now done with the giant powers of satellites or the tiny circuits of the iPod. Everything being released is better, faster and more fantastic than everything released before it? Technically, by the earlier stated definition, we should be in a golden age of electronics?

But are we?

The only flaw with that argument is that if we are in a golden period of electronic and technical innovation, then we should enter a period of decline and mediocrity at some point. It’s hard to envision new electronic items becoming worse in quality as time progresses. Unlike say, film and cinema, where there is no way that a film like Speed can be compared to Citizen Kane – the drop off in quality is simply too great. But, the difference between an iPod Mini and an iPod Nano is negligible at its most visible.

And since technology is always on an upward trend, can it then be debated that since the introduction of the last industrial revolution in the late 1800s, we have constantly been in a period of electronic excellence? Technological advancements have just been that – advancing. It’s rare that a new and important electronic release stepped backwards rather than forward: the Xbox 360 is much better than the original Nintendo. A DVD player is exponentially better than a Betamax.

If one had to pinpoint a time period where electronic and technical advancements were being produced and released at such an impressive rate, it could be argued the periods between 1919-1945. The monster of war required a great many food sources, and in order to get the upper hand, technological edges needed to be found at any and all costs. Necessity is deemed to be the mother of invention, and the requirement to survive, win and defend a way of life resulted in some of the most impressive electronic creations in an incredibly short period of time.

Back to the original question at hand, which is are we in a golden age of electronics? It would appear that we are, because the ability for electronics to connect the world has never been greater. If that is the case, then what exactly is the next goal for technical innovations? Video games and iPods and camcorders can be improved in design, but what about function? Is a digital camcorder destined to only become the feeding tube for YouTube, or can it do more?

Perhaps the question about the golden age of technology will never be answered, and maybe that’s a good thing. It would be unwise to declare that we have reached the pinnacle of invention and that everything else from here on in will be a disappointment. And while we may not be able to define the era we are in, that does not prohibit us from enjoying the benefits and innovations of it.

Used Computers are by far the cheapest solution

Cheap computers are everywhere.  Dell is offering some stupidly priced computer hardware at the moment, all with a view to beating the online shopping market.  The point is, this isn’t really conducive with an ethical, environmentally friendly solution and is simply keeping Dell gainfully employed.

Low cost computers can also mean second hand and there’s a few good reasons to buying used.

1) The processing power of a used computer may not be much less than that currently on offer by the Manufacturer
2)  You don’t need the latest and fastest computer to produce a spreadsheet, surf the web, write emails and write letters.
3) A used computer has been road-tested.  It’s not going to fail on you any time soon.

There’s other reasons to get a used computer, but basically, that second hand unit you’ve been looking at will probably do most of the things you need your IT hardware to fulfill.  Even the monitor doesn’t have to be new.  You may think that a brand new flat screen TFT is best with lower energy consumption  and a small footprint, leaving loads of desk space. A flast screen monitor may be a great solution for some, but a used CRT screen is better for gaming, graphic design and photography.  They’re a proven and refined technology.  They offer multisync solutions, allowing you to change resolutions and refresh rates on the fly, with every resolution being native (TFTs have one native refresh rate and the rest are emulated).

A CRT is pretty much as good as a TFT when it comes to energy efficiency.  There’s only a few watts in it and as long as you turn everything off at the mains once done each day, you won’t see a marked increase in your electrical bill.  A naturally flat CRT screen will give you the added benefit of super fast refresh rates and be able to keep up with the latest games on the market- all at a very low cost.

Cheap used laptops do however have some downsides.  These include the battery life and general wear and tear of the unit from it’s previous owner.  Saying all that, as long as it’s been relatively well looked after, it’ll give you a great solution for emails and writing on the move.  Not only that, but if it’s stolen, you won’t have lost as much money.

Keep Your Notebook Computer Longer! A Safety and Care Guide for Laptop Computers

Laptop computers – also known as notebook computers – have become an important part of our lives. They are more affordable than ever and as popular as cell phones. A laptop computer has a versatility that the home PC does not provide. With its smaller size it is portable and easier to carry along. This makes it convenient to use in many situations. You can take it to work and back home as well as take it on more extensive travel.

Laptop computers are not just for older working people anymore. Because of its ease of use, more young people are using them for school and college. They can access the Internet almost anywhere and provide updates for work, research, and even games.

Taking Care of Your Laptop or Notebook Computer

It is important to take care of your laptop computer and protect it from accidents. They are designed for heavy use but common sense will tell you that you need to be prudent in your treatment.

One of the first recommendations is to buy a case designed for a notebook computer. These are made with padding to protect your laptop computer from wear and tear and protection in case you drop it. It is not good to carry your notebook computer unprotected or in a purse or backpack. You can easily find a case by shopping online where you will find 1000s of products to choose from.

Another important tip for laptop computer care is to keep food and drinks away from it. Even a small amount of liquid is enough to ruin the delicate components in the laptop computer. It means almost certain replacement, and most warranties will not cover it. It is not worth the risk to lose all your data.

Protect Your Notebook Computer

When using your laptop computer you should always use a surge protector. An electrical surge may not hurt it one time, but continued surges could destroy it. If you are using a cable or dial-up modem during a storm, be sure to unplug it. Lightening can travel through phone lines and ruin the laptop computer.

You should not leave your notebook computer in a cold environment. This can cause condensation when you return it to a warm area and could cause the circuitry to short it out. If it has been in the cold, let it warm up before turning it on.

When traveling with your laptop computer, be sure to charge all your batteries before you leave. You might not know when you will be able to charge them again. On a long trip, take extra batteries to avoid this problem.  By shopping online, you can find the supplies you need as well as other products such as iPods, jewelry, games, toys, sporting goods, pet supplies and cell phones – even free gifts.

Do not leave your notebook computer unattended and do not check it as baggage when flying. Keep it in your hands at all times to avoid the possibility of theft. Don’t try to disassemble or repair your laptop computer; this is a job for professionals. You may inadvertently cause more damage by your lack of knowledge.

Shopping Online

When you are ready to buy a laptop computer, cell phone, iPod, or other electronics, shopping online will provide everything you need.

History Of The Computer; The Emergence Of Electronics

The history of the computer inevitably includes the development of electronics, we look at the explosive (!) growth of electronics in the late 1930s and early 1940s.

If anything could be said in favor of war, it may be that it speeds up the development of technology. Of course much of that technology is employed in killing people and destroying infrastructure, but there are also things which could be considered beneficial.

Electronics was around in the early part of the 20th Century, wireless, or radio, was in its infancy at the time of the first world war. Radio broadcasting came into prominence in the ’20s and 30’s, Television started in the ’30’s.

The second world war, from 1939 in Europe, and a couple of years later involving the USA, ended in 1945. Radar (Radio Aid To Detection And Ranging) was developed from early experiments, just prior to the war, in Britain and Germany. There was rapid development in the field, and, by the end of the war, Radar was being used in several fields.

Aircraft Navigation – Using ground transmitters in sets of 3, widely spaced, to give an aircraft using a receiver a method of pinpointing its position. This is a similar system to that used in gps today, substituting satellites for the ground stations.

Targeting – A beam was transmitted from a Radar station in England so that it intercepted a target in Germany. An aircraft could fly along the beam, guided by signals, dots or dashes, if it strayed off the beam, left or right. Known as flying on the beam.

Interception – a series of ground stations around the South-East coast of England, feeding into a central control room, where their tracks could be displayed, significantly assisted in the Battle of Britain (1940).

Airborne Interception (AI) – Developed towards the end of the war, used a Tranceiver (transmitter/receiver) in a night fighter to find a target in the dark, or bad weather, and track it to within firing range.

Beacon – A tranceiver was located at the end of a runway so that ground staff could guide a returning aircraft to land in bad weather, this became more and more sophisticated, developing into GCA or Ground Controlled Approach.

Shipping – radar equipped vessels could track other vessels in darkness or fog, whether peacefully or aggressively.

Many other sytems were developed or initiated in that 6 year period. Knowledge of electronics, and what it could be used for vastly increased. In parallel with the development of radar, other fields of electronics were also advancing, under pressure from the requirement to improve the technology.

Long range guns on ships or in the field needed to be aimed accurately. The calculations required in ballistics to aim a gun so that you can hit the target, or aim a V2 rocket so that it hits London from continental Europe, are phenomenal.

This, then was the scene at the end of the war. We knew how to tackle large calculations with speed, and we had developed a new concept in electronics, Pulse Technology. This is so called because radar uses short pulses of high energy, for two main reasons.

1. The pulses can be coded. For example, in the Navigation example we looked at, 3 ground stations transmit a signal whose source needs to be identified. One transmitter could transmit a series of single pulses spaced say 10 milliseconds. A second could transmit a pair of pulses at 10 millisecond spacing, and the third 3 pulses. A chart would tell the navigator where the pulse sets were transmitted from, and the distances obtained from the radar set used to locate the position on the chart.

2. The power, or strength, of the signal. A continuous radio signal, like a radio broadcast, takes a given amount of power. However, a 1 millisecond pulse every 10 milliseconds, uses only one tenth of the power, on average. So a radar transmitter can have a much greater range for the same power. This is is especially important in a primary (transmit and receive) radar system, where we must detect the reflection of the signal we transmit. Likewise a secondary (receive) radar system, for example the navigation system above, will have a bigger range.

Next we will look at how early computers were now possible due to these developments.

Computers and electronics while traveling overseas

Well i’m off on my holidays,this time abroad,the good ole USA,but i still need to be “on-line” on a daily basis for my personal & business needs, so i have brought some lightweight products ,that don’t take much room and are easily transportable
