High-voltage USB-C batteries keep your notebook computers charged and away from patented plugs.
Portable batteries have become more elegant, cheaper, smaller and faster to charge their technology. More improvements are on the way, thanks to GaN gallium nitride, an alternative to silicon that is more efficient in space and energy than can be found in some wall chargers. As more laptops and other high-powered devices adopt USB-C and move away from the patented charging sockets, there is a chance that large, powerful batteries can increase their power adapters and, ideally, allow them to charge multiple devices at the same time.
We have tried some models that are available now, as well as some that are coming out soon. The list includes SuperTank by Zendure, HyperJuice by Sanho and Tanker Elite and Tanker Xtreme by J-Go Tech. Each of these batteries has USB-C Power Delivery ports capable of delivering at least 65W of power and in most cases, up to 100W. This means that they are likely to be powerful enough to charge most laptops and replace some wall chargers.
These batteries do what you expect: they charge your devices quickly and keep them alive for longer. The most economical battery packs, suitable for devices with lower power requirements, do an excellent job of keeping phones and most tablets running for days.
Once upon a time, anyone who knew how to do anything with a personal computer away from switching it on would have consistently been called a "geek". Definitely, if you spend more than one hour each day using a computer for anything at all together work, you would have been thought to be uncool. Neverheless, recently the usage of computers has become something that more people do than not.
The very idea of something like Facebook 10 or 15 years ago may have set alarm bells buzzing among the awesome youngsters. Computer users socializing were similar to dogs rollerblading – not usual, unsettling to look at and something to be discouraged. But as personal computers have got cheaper and simpler to use, social networking is now very popular.
The boundary between "geek" and "chic" has been refined in many cases to a point in which it does not exist. In fact, the idea of "geek chic" has really taken off, and it's not even an issue for many youngsters who have matured in an age in which the Internet is pretty widespread. Now it's people who do not use personal computers that are regarded as a bit weird.
Like every social change, there can be discussion as to whether or not this has had overall appealing results. Undoubtedly, someone who works in computers or just considers them a pastime do not need to cringe every time they are asked what they're into. With any kind of mass use, a sensation can appeal to undesirable activity and promotion, but on balance most people seem to be satisfied with the diversity it has bought.
Computing And Language – A Marriage Made In Hell?
Around two decades ago, "computing language" meant a single thing, and was something simply understandable to educated programmers. Yet today, it is more likely to refer to a form of slang that is used among online communities. This has introduced combined results, many of which may be very good and others very, very bad.
Some people will probably be aware of "Leetspeak", which is really a specific term made op from characters other than letters – and therefore can not actually be "spoken". It's most commonly used among cyber-terrorist, gamers, or people seeking to be seen as related to those areas, and to the untrained eye is nonsensical and irritating.
The use of "text speak", or more frequently "txt spk" is also partly a result of the introduction of the Internet. Generally attained by dropping vowels from words (although not unnecessarily every vowel) along with the introduction of numbers and emoticons made from punctuation marks, it results in phrases like, "Gr8! So ur in2 txt spk? Me 2!" Those who desire to be taken seriously avoid it.
Lolspeak, most commonly viewed on the Lolcats website, is a mutation of text speak and took its name partly from the text speak abbreviation "lol" (laughing out loud). It combines text speak with the deliberate usage of an infantile form of speech – indeed, the Lolcats site is alternately referred to as, "I Can Has Cheezburgr?" To novices, these kinds of dialects are all very difficult.
If you're in the market for a tablet computer, this quick review of the top five models will give you a place to start.
The Apple iPad 2 is the best-selling tablet on the market. A faster dual-core Apple A5 processor, better graphics, twin cameras, and a 33-percent thinner design than the original in combination to the huge app store selection set the iPad2 apart from the competition. The 9.7 inch display with 768 X 1024 pixels falls short of the Motorola Xoom. However, the 10-hour battery life, iTunes, and the best selection of apps, make the iPad 2 the tablet to beat.
The Samsung Galaxy Tab is one of the best android tablets available. The hardware is sleek, light and has a great 10.1 inch-screen. The dual-core processors boot up smoothly and quickly. The updated Honeycomb OS easily loads web pages, plays video and multiple apps. The built-in cameras and speakers get the job done. The only drawback is the lack of USB, HDMI, and SD card slots. The versatile Galaxy Tab is only limited by the current lack of android apps.
The PlayBook by RIM has a browser that puts the Web in your hands. Coming in at just 0.9 pounds, 0.4 inches thin, and with a 7 inch-screen, the PlayBook is actually, truly portable. Aided by Adobe Flash 10.2 support, the QNX-powered OS loads sites in full desktop splendor. The dual-core processor lets you multitask on a high resolution display with more pixels than an iPad. With full HD playback, an HDMI out, and with cameras front and back, the PlayBook packs a lot into a little space.
The Motorola Xoom, although a little heftier than its main competition, is gaining in popularity. This tablet boasts a 10.1 inch-screen with the same 1280 X 800 resolution as a laptop. The super-fast dual-core processors run Honeycomb OS and support 4G download / upload speeds. One drawback is the built in speakers. However, when you couple the 10 hours of video playback with the dual cameras and micro HDMI slot, the Xoom is one cool tablet.
HP TouchPad, a full-sized tablet, is larger and heavier than most of its rivals. The 9.7 "IPS display with a 4: 3 aspect ratio and 768 X 1024 pixels is the same as the iPad 2. The display is detailed enough for fine text, but has low brightness makes it difficult to view in full sun The TouchPad comes with a micro USB port, stereo speakers of good quality, but surprisingly, only one camera.
So if you're looking for looking for tablet pc, these tablets are five of the best on the market in 2011.
You can probably immediately guess the differences between desktop computers and laptops. After all, the size is a very obvious difference. That size correlates with everything that makes a laptop. The circuitry is smaller and so are the vital components. A desktop computer is not as mobile as a laptop.
It does not come with its own battery to fuel its processes and you have to have a separate screen for the monitor. The laptop is essentially a smaller version of your desktop computer that is used for its mobility.
Once you are familiar with the differences between desktop computers and laptops, you will need to turn inside to see the minute differences. The desktop will utilize a different memory module than the laptop. The difference is in the Random Access Memory and the type of modules that are used. The desktop uses a DIMM (Dual In-line Memory Module and the laptop uses a SO-DIMM (Small Outline Dual In-line Memory Module).
The SO-DIMM is more or less equal to the DIMM in power and speed, but since laptops are space constricted, they are smaller and must utilize less space for the same comparable speeds. There is also a different procedure for upgrading notebooks in comparison to the desktop computer.
You will also need to know that there is a distinct difference between an Apple memory and that of a Compaq memory. It is important to only buy products that work with your particular model and series if you want the upgrade to work well for your particular laptop.
The basics of laptops are pretty easy to master once you have the right information. When you do get all the information you need, do yourself a favor and store it in a safe spot for future reference.
Also keep any accompanying literature or information that may come with the computer memory upgrade module. By keeping the information handy you can always have it on hand when you need to buy more parts and pieces to help your laptop run even better.
The kids nowadays cannot imagine their home without a television set, a computer, a phone, being influenced a lot by mass-media, which often gives them a wrong perspective of the world they live in. After several studies on the impact of the computer on kids, psychologists and paediatricians have reached the conclusion that computers can be dangerous if they are used in an uncontrolled manner. Thus, the kids who spend more than five hours in front of the computer are exposed to obesity.
An uncomfortable position in front of the typing board which is sustained for hours can affect the child’s position and the monitor can hurt their sight. Spending their time in front of the computer means that they don’t learn to share their things, to wait for their turn and that they don’t get to learn some basic things, such as manners. Kids needs to interact with other kids and adults. They need to experience things themselves, not by using a computer.
Some of the boys identify the user of the computer with tough, sadistic ad rebel characters. A child is addicted to the computer if they are tired all the time, if they sleep very little, if they have problems in school and so on. They don’t learn anything, they don’t do their homework, they don’t have other hobbies, they isolate themselves from their friends, they are frustrated and rebellious, especially because their parents don’t understand the problem and don’t see the attractive and fascinating part about using the computer. That is why parents should make a balanced schedule for their kids and explain them why it is very dangerous for them to spend hours in their chair, with their eyes stuck on the monitor.
They should think of when their children are allowed to use the computer and to check them from time to time, mentioning the consequences of their disobedience, but also the rewards for their obedience.
Since the world's first ever electronic digital computers were created within the UK and US during the 1940's times have changed massively, and the exact same can be said for the technology that powers them.
Unlike the 1940's where computers were the size of a small room (and sometimes a large room) with gigantic internal components and fans which would shame a NASA space craft cooling system, computers are now extremely ergonomic with some examples quite literally fitting in to the palm of your hand and desktop computers being the size of a hard back book.
Way back when computers were first designed these machines were available only to governments and the scientists that created them, a far cry from where we are today with billions of people being connected online through a desktop computer and even more people owning a portable internet connected device such as a smartphone, tablet pc or portable gaming console.
But how did we get to the computing stage which we are today, and at what turning point in computing history did computing become a consumer indulgence?
A brief computer history timeline – In 1936 Konrad Zuse created the world's first ever programmable computer named the Z1.
– In 1962 the first ever video game was invented by Steve Russell at MIT, named 'Space War'.
– In 1969 the world's first ever internet was invented by ARPAnet
– In 1974 the world's first ever consumer focused consumers were born, the Scelbi & Mark-8 Altair & the IBM 5100 computer.
– In 1981 IBM created their first ever consumer computer, the IBM PC – Home Computer.
– In 1983 – 1984, Apple created the first home computer with a GUI (graphical user interface).
– In 1985 Microsoft releases Windows, which would soon become the domineering software on all consumer based computers.
The above brief computer timeline misses out a fair few developments within the computing industry, however the most important ones by far to me were the invention of the Z1 by Konrad Zuse and the first ever computer with a graphical user interface by Apple. You do have to say with that analysis that though without Zuse the computer may have never been developed so quickly if at all and without Apple the first ever solid consumer computers would have been awful to use for the average consumer.
Comparing 1985 computing when the first version of Windows was introduced to now brings up some key night and day differences.
For starters computers of the past were not as well designed as they are today, they were in no way as powerful as they are today, and they in no way sold as well as they do today. In part, everyone in the computer history timeline had their own part to play in the success of the computing industry.
It is the advancement of software, hardware and design which has brought our computing needs to what they are today, and without all three of these contributing factors the history of computing may have taken a very different shape to what it looks like today.
When the word computer is heard we at once think of the desk top PC left on the desk at home or in your office. True that it is the PC we call a computer but these electronic brains are embedded in many instruments in day to day use from toy cars to fighter jets.
The earliest computers were made in the mid 19th century. The were very large sometimes filling a room the size your of your bed room. These were improved and with the advent of digital technology they improved vastly and reached the present day state.
Basically to complete a computer there are two things which should work together. They are hard ware and software. Hardware is the physical instruments you can see while software are the programs running inside the machine making it to work. In a basic computer there are three parts in the hardware. They are the input device the output device and the central processing unit. The basic input devices are the key board and the mouse. The basic output device is the monitor. The central processing unit is the real computer which does the calculation and execution of programs.
Software too has two sets. One is the operating system which makes the connection between the hardware and the programs. The other programs are the various programs used by the computer they could be word processers, spread sheets, programming software and so on.
Though the above is the basic PC presently it has developed into various branches. While basic computer has evolved into smaller laptops note books and net books the microcomputers are embedded in many instruments like the toys, games and industrial robots.
The computer is keeping on developing and soon we might be able to see a car being driven by one of these. Still the PC at home left on your desk is your faithful friend.
There’s little doubt that the most popular tablet is the iPad. Tablets, such as the iPad have enabled users to harness the power of the PC in a more compact and touch enabled functionality. Tablets are superior to smart phones and laptops in many ways. The following are the reasons that make tablets such as the iPad superior over your laptop or smart phone.
Tablets let gamers play games with a large enough screen, without the use of mouse or a flat surface, one can simply lay down and play games on their iPad – if they like.
For students and readers alike, tablets compared to smart phones and laptops make better e-readers. Their size and portability can be compared to a book, this design and capability features make tablets great for reading e-books or PDF, word or other
Comparable capabilities to a laptop:
Next, some tablet such as the iPad, can be a better alternative to the laptop – but it depends on how you utilize them. Think about it, tablets can let users video chat on Skype, send email, surf the web and you can do all these things without having to get off your couch or bed.
Great for office meetings:
Tablets are not just built for play or fun, they can make excellent tool for enhancing workplace productivity. For once, if you are in office meetings, you can take notes using your tablet. You don’t need to run back at your desk and re-enter all the important information on your laptop or desktop. You can simply share your digital notes on your cloud account and then access it on your work computer.
Better entertainment during long flights:
If you own a tablet, and have used it during long flights, you know how convenient it is to watch shows and movies on them, as compared to smart phones with their small screen and laptops with their bulky size and battery consumption rate. One can say that tablets are built for non-stop entertainment for long travel.
Quicker startup times:
Some tablets running android or iOS can load significantly faster than your laptop. This means that you don’t have to wait five minutes or longer for your computer to load up. A tablet can, on average can load-up in less than two minutes. This means that you can quickly get to what you want to do, and at some point, quicker startup times can make all the difference.

Today we’re gonna talk about portable battery chargers. They’re these little things you carry around and when your phone or your ipad or whatever gets low on juice you plug ‘em in and get to keep using your DEVICE. It’s a battery… to charge your battery! They’re popular for travelers, ever present on the conference circuit, and I hear you see ‘em in schools more as teachers get more tolerant of MOBILE PHONE USE. You got a buncha classes or panels or whatever throughout the day, gotta take photos or notes or post to twitter, use maps, you’re gonna run through your battery really quick. And that’s, I mean, you can’t have that right? Dead phone? YOU MIGHT AS WELL BE DEAD. Which brings us to something called, “Battery Anxiety” also referred to as “NOMOPHOBIA” (fear of being without one’s mobile device). We’ve all felt it, that sinking feeling while browsing Instagram or Facebook when you see that little red bar appear saying you’ve got less than 20% battery remaining. But why do we feel this way? Let us know what you think in the comments below!
