Computer Mouse Tips To Know

While the mouse may seem like a trivial aspect of your computer, there are probably a lot of things you don't know about its use.  Here are some great tips on how to maximize your use of the mouse, which will increase your overall productivity on the computer.

1. Shift Key and Mouse Click In text editing programs like Microsoft Word and even on your regular webpage, you can highlight all or portion of a certain text using the Shift key and clicking on your mouse. Place the cursor (the sign of the mouse) at the beginning of a paragraph and hold down the Shift key. Click at the end of the paragraph to highlight the entire thing, or wherever in the text that you would like to end the selection. Another tip: Holding down the Alt key while highlighting text in a text editor will allow you to selectively highlight the text. This is most useful if a paragraph or other text is in a column. 2. Use the Scroll Wheel to The Max Most computer mice have a scroll wheel in between the right and left click buttons that allows you to scroll up and down the page by moving the wheel. However, this wheel can be used to do much more than just scroll! - The mouse wheel can be used as a button. Pressing down on the wheel is like clicking with a third mouse button. You can press down on a link to open the web page in a new tab in your browser. It can also be used to close a tab in the browser by clicking the wheel on an already open tab. - Hold down the Shift key as your scroll up and down in your Internet browser to quickly move back and forward between webpages. Scrolling up goes forward while scrolling down goes back. - To zoom in and out on a web page or document, hold down on theControl (Ctrl) key and scroll up to zoom in, scroll down to zoom out. - Some mouse wheels can be pushed left or right to move backwards (left) and forwards (right) on a webpage. 3. Select With Double or Triple Clicks Words can be selected by double clicking the word. If you want to highlight an entire paragraph, click the mouse button three times on the text 4. Right-Click You can use the right-click when you want to highlight text or wish to view the properties of an object. For example, if you highlight text, you can right-click on the highlighted item and copy it, then right-click anywhere else to paste it. Another tip: If you right-click text and drag it while continuing to hold the right mouse button, when you let go you will be given the option to move or copy the text. This will save you the extra step of having to right-click again where you want to paste the text. 5. Ctrl Key and Mouse Click When you hold down the Ctrl key, you can left-click to select multiple files or highlight multiple sections of text. You can also hold down the Ctrl key and use the down or up arrows to select the text. 6. Use Mouse Side Buttons Newer computer mice have side buttons on the side of the mouse (next to the usually right and left keys).  These buttons can be programmed to do most anything, but by default, the left-thumb button can be used to go back on a web page, and the right button to go forward. 7. Use Snap to Feature Windows has a handy 'Snap To' feature that will automatically move your mouse to buttons in the dialog box, such as the 'X' to exit or the '_' to minimize. For example, to close a window, you may get a prompt asking if you really want to perform the task. With the Snap To feature, the mouse will automatically move to the OK button so that all you have to do is click if you agree. To enable this feature, open the Mouse properties under the Control Panel, and check 'Snap To' under the Pointer Options tab. 8. Manage an Open Window Double-click on the top title bar of a window to maximize the window or, if it is already maximized, to resize it. Double click on the icon for the window in the top left corner to close that window. 9. Move the Mouse With Your Keyboard Instead of using a regular mouse, you can enable your computer to use the number pad instead. This trick takes some time to master, but it can make your use of the computer much more efficient. 10. Select with double and triple click  This is the most used tip but for the completeness of  this post  i have mentioned it. You can select a word by double clicking it. And if you want to highlight the whole paragraph then click the mouse button three times on any paragraph. 11. Hold Your Mouse Correctly! There is no need to hold onto your mouse for dear life! The mouse will move well with just a light touch, which will also protect the health of your wrist. This is important for those that use the computer for hours a day, because incorrect posture on the mouse, or keyboard for that matter can cause a lot of unnecessary pain. Customize your mouse Finally, if you have a mouse with more than two buttons, installing the included mouse software allows you to customize the mouse even more.  For example, if you don't use the side buttons to move back and forth in a web page, change it to something you do more often, such as switching between open windows or opening the calculator.

Li-Fi could soon replace Wi-Fi with speeds up to 100 times faster

LED lamps in our houses could soon provide you with blazing-fast Internet speeds, leaving the  old Wi-Fi connection in the dust. It's all thanks to a new technology called Li-Fi, short for "light fidelity," which transmits information wireless via visible light.

What is Li-Fi?

Light Fidelity (Li-Fi ) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas ^] and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or Cellular network), or even a replacement in contexts of data broadcasting. It is so far measured to be about 100 times faster than some Wi-Fi implementations, reaching speeds of 224 gigabits per second.

It is wireless and uses visible light communication or infra-red and near ultraviolet (instead of radio frequency waves) spectrum, part of optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations.

How fast will be Li-Fi?

The thing that makes Li-Fi so revolutionary is its incredible speed, up to 100 times faster than Wi-Fi. With that speed we can download contents of 23 DVDs in just one second using a Li-Fi connection. Laboratory tests have shown speeds of over 200 Gbps. It could solve the bottleneck problem that currently exists with our Wi-Fi networks, which will only be compounded as an estimated 50 million different objects and devices are expected to be connected to the Internet by 2020.

What is the disadvantage of Li-Fi?

For all of its advantages, Li-Fi does has one drawback. Because it transmits data with visible light, our device has to be in a lit room for it to work. 

Forget about using it in the dark, or out in the bright sunlight for that matter. Sunlight interferes with the artificial light that is transmitting the information. Li-Fi also can't pass through walls, for the same reason that the light from a closed room doesn't illuminate any surrounding rooms.

Will Li-Fi replace WI-Fi completely?

So Wi-Fi will be continued to be in use even after Li-Fi gets widely implemented. The idea will be to use them in tandem, to get the benefits of each .

Tips for saving ink and money while using Inkjet printers

Most of the Inkjet printers cost a lot of money in maintenance since they dry very fast and we have to refill or replace the ink cartridges often.

By following these tips on the right way to use the printer we can save a lot of ink and money.

1) Avoid purchasing  cheap printers.

There are a lot of cheap printers in  the market today. It's important to be careful when buying them as the companies selling them might be looking to make their profit off of the ink cartridges rather than the printer itself. When buying a printer you should always look at the prices of the ink cartridges and their "life-span".

2) Use the right font.

A few years ago, several American students shocked the world by showing that if their government switched to a thinner font, it could save about 400 million dollars a year. While you won't be able to save that kind of money yourself, using a simple and thin font ( Garamond) can improve your ink usage by about 20%.

3) Use the low-quality setting.

Unless you are printing photos or really small items, there is no need to print in the higher printer settings. You can change this in the print setting after you send a document to the printer, usually under "print properties" or something similar. And unless you really have to use color, printing in black and white is recommended.

4) Use recycled cartridges.

Many shops today offer none-original ink in recycled packs, while some even 

offer refills if you bring your own empty cartridges. 

Printer companies claim this might harm your printer, but there is no clear evidence to support that.

5) Try using a refill kit at home.

Some ink cartridges can be refilled with a simple kit you can use at home and it's often very cheap to buy at stores. 

The big downside of this is the potential mess it might create and the work you will need to do each time you use it. However, if these things don't bother you, it's a pretty cheap way to do things.

6) Keep printing.

Just your car tells you it is out of gas even before the tank is empty, your printer will tell you it is out of ink even when there is still some left. This means that you can keep on printing, even with a low ink warming. It just means the writing might be a little grayer. It might also help if you just take out the cartridge and put it back in.

7) Save paper.

Printing paper can be just as expansive as ink and you can save a lot of money by printing on both sides of each page. Most modern printers have an automatic option to do so, you just need to turn it on. Take a look at the printer manual to see how it is done.

8) Save room when printing presentations.

If you are printing a PowerPoint presentation, you can put about 4 slides in a page and still read them with ease. 

This will save you both ink and paper. To do so, just look at the print menu on PowerPoint and change the settings to your liking.

9) Don't print the test paper.

Many printers do a test printing when you turn them on with no real reason. 

Look at the printer manual to find out how to disable this and only use your ink and paper on what you really need.

10) Print something once a week.

If you don't use your printer for a long time, the ink in the bottom of the cartridge can dry out and then the whole cartridge becomes useless. To prevent this just print out a single line of text once a week. 

11) Wait before turning off your printer.

After a print job is done, the cartridge is returned to a protected and closed part of the printer. If you force it to shut down before it can do that, you risk the ink drying up and maybe even leaking.

12) Only print the final version.

There is no bigger waste than printing something only to discover an error and then having to print it again. It is important to double-check spelling and page layout before you print a document to make sure you won't need to do it again.

How to solve Common Computer Problems?

Anyone who owns a computer will encounter technical difficulties at one point or another, often causing no little amount of frustration. While some of these technical difficulties require professional help, there are quite a few that can be easily solved, even by novice users.

Before you start troubleshooting your technical problems, restart your computer – you’d be amazed at how many problems a reboot solves. After you’ve restarted the computer, make sure that your operating system is up to date. Sometimes the problem is a result of an old version of some file or another, which an update can correct in minutes. Making sure that your Windows Update feature is active help in fixing bugs and improving system performance. If you have a peripheral that is misbehaving, try turning it off and on again. Problematic USB devices can be switched to another USB port. Now that we’ve exhausted the basics, let’s deal with the 10 most common PC problems. 1. Slow Computer First, you need to know that videos or websites that take a while to load are not necessarily slow because of your computer; they can also be affected by network interferences. If your computer is slow in opening programs, things stall or hang while in use, or the boot up process takes more than a couple of minutes, then you might have a slowness problem on your hands.

Now, once you’ve established that the computer is the culprit, check the main suspects - A Full Hard-Drive (HDD) and too many processes running in the background. When the hard drive that holds your operating system (usually designated as C: ) is full, the operating system can’t write files quickly, as it needs to search and allocate space for it. The searching process takes time, which will result in a slowdown of your system’s performance. Delete any unneeded files such as movies, photos, music, or move them to another hard drive. Use a program Visipics to remove any duplicate images. Uninstall any programs you don’t use anymore

Alternatively, having too many processes running in the background will also slow down your computer, as they require both computing power, as well as the faster, short-term memory – RAM. To clear it, click on the start button, in the search field, type: msconfig and then go to the “Startup” tab. Now, you don’t want to unmark anything that is a Microsoft process. What you should look for are names Google Update, AdobeAAMUpdater, Steam Client Bootstrapper, Pando Media Booster, andSpotify. These can be unchecked, and you should be able to feel the difference after a startup. 2. The Internet is Slow Feeling your downloads, browsing, and streaming music and videos takes too long? Check that your slowness is Indeed, network related. Go to Speedtest.net and run a test to see if you are getting your package’s worth of speed or not.

Minimum speeds should be at least 50% of the ISP’s advertised speeds, and your ping should be under 100. If your results do not correspond with these, then something is hogging your bandwidth, or there’s a network problem. First, check to see that there aren’t any torrent clients running in the background. They will often minimize to the tray and continue downloading and uploading files, which uses a lot of bandwidth. Next, check that your network card’s drivers are up to date (if you haven’t updated your operating system, this might be the time). Next, try turning your modem off and on again. If it has no On/Off button, just unplug and plug it back in. If none of this helped, call your ISP and tell them there’s a problem on their end, and let them fix it. 3. The Computer Keeps Restarting This could just be the result of a series of Windows Updates, which require several reboots sometimes. Take a look and see if the restart process mentions “Updating Windows”, if so – just have some patience, it’s worth it.  Now, another cause might be mechanical – Is your computer making odd noises? Is it unusually hot? If your computer is not brand new, you might need to clean the dust that accumulated inside the box. Once you’ve exhausted all of these tests, consider taking your computer to a specialist. 4. I’m Getting Popups All the Time If you’re not browsing the internet, yet are still getting popup ads, it’s most ly a form of malware called “Adware”. These are sneaky programs that can be tricky to get rid of. As in #3, run avirus scan and a malware scan, and search online for “(advertiser name) adware removal” – you should be able to find a solution.

5. My Search Page Looks Weird There’s a type of malware called “Browser Hijackers”, which take over your browser and direct you to sites they want you to see, for which they usually get paid. These nasty pieces of software also steal your private information, such as searches, personal details, and even credit-card number. Follow the instructions in #4, but if all else fails, go to a specialist. 6. I Keep Disconnecting From the Wi-Fi Wireless problems can occur because of several reasons (router, computer, ISP). If your Wi-Fi signal is weak, it can cause disconnections and slowness, so make sure you’re in range and are getting decent reception. Next check that your computer’s wireless adapter has up-to-date drivers. If none of this works, call your ISP and see if they can help. 7. Constant “Security” Warnings While Browsing While this may be one of the most annoying problems, it’s also incredibly easy to fix. Check that your computer’s clock shows the correct time and date. If it doesn’t, right-click on the clock and select “Change date and time settings” to correct it manually.

8. The Printer Won’t Print If your printer has ink, paper, and updated drivers, try unplugging it, then plugging it back in. If the problem continues, double-click on the printer icon on your taskbar and check to see what the printing queue says. Click on the “Printer” menu item in the printer window and make sure that “Use Printer Offline” is not checked – this will stall the printing queue. 9. Email Attachments Won’t Open If you can’t open the attachment, it’s probably because you don’t have the right software. You can always google the type of file it is (such as .PDF, or .RAR) to find out how to open it, or use the site http://fileextension.info/  to find out what the file is and how to open it.

10. Why Doesn’t This Program Work on My New PC? If you recently upgraded your computer, it’s possible that the old program is not compatible with the new operating system on your computer. If you’re using an old installation file, try searching for a new version online. Additionally, if you’ve changed from a PC to a Mac or visa verse, then you should know that the two systems are incompatible, so programs from one won’t work on the other. If it’s an online game that is driving you crazy, maybe you need to update your Flash or Java plug-ins.

*What if I Have No Idea What I’m Doing? Knowing your limitations is a good thing. If you don’t feel you’re skilled enough, ask someone for help, or go to a professional. There are also many tutorial videos on YouTube, so all you have to do is search.

Mistakes That Can Damage Your Computer

In the last 20 years, computers have become a necessity. People can spend hours in front of one at work, only to come back home and use their personal one, for which they paid a handsome sum. Sadly, many people unknowingly engage in actions that are harmful to their computer. A list of the 16 most common things we do incorrectly, and how to do them without possibly needing to get your computer fixed are furnished below:

1. Blocking the Computer’s Vents Trying to save space can often lead you to place your computer closely against the wall, desk, sofa, curtains, etc. The vents are vital in keeping the computer cool, and anything that blocks them may cause it to overheat. High temperatures damage the internal circuitry, so keeping the computer nice and cool by not blocking the vents should be a priority. 2. Deleting System Files When we use our computer, we sometimes clog the hard drive with pictures, movies, music, and other junk. When the hard drive is full, it works harder, making your computer sluggish. The problem arises when inexperienced users try to clear up space by deleting files they don’t know, and more often than not – they delete important system files. Deleting these files can render the computer inoperable, or prevent certain features from functioning (example: deleting system files related to the sound drive can disable your ability to listen to music, etc.) Don’t delete any files ending with.SYS,.DLL, or.EXE, in particular from these directories: Program Files, System32, Windows, Users. 3. Cleaning the Screen with Liquids When you want to clean your computer screen, you probably use a wet wipe or some basic cleaning detergent, but this may actually damage it. Any type of liquid can cause corrosion if it gets into the screen and detergents (even natural ones) may damage the special coating on the screen. The best way to clean a computer screen is by using a dry microfiber cloth, or the same kind of cloth you use to clean your eyeglasses. 4. Pushing the CD/DVD Tray to Close it Even I do this from time to time, instead of pushing the open/close button on the drive. You may think that these actions are the same, but when you apply force to the drive you can break the opening and closing mechanism. So next time you’re closing the drive – use the button.

5. Using the Same Password It may be easy to remember your password this way, but it also makes it easy for hackers and criminals to log into your private information, or worse. You wouldn’t want to use the same key for your home, car, and bank account. If you hate remembering passwords, simply get a password management program LastPass or LogMeOnce. 6. Not Restarting After Installing New Software When you install a new piece of software to the computer, some may ask you to restart it. You may feel that it’s a waste of time, but these requests are not mere whims by developers. Some applications need to start up with the computer to function properly, so using them without the initial restart can result in t hem not working properly (or at all). Even if you don’t have the patience for it, make it a habit to restart the computer when prompted to. 7. Browsing the Web without an Up-to-Date Antivirus This is a HUGE NO-NO! One of the most vital things you should have installed on your computer is an antivirus software. Browsing the internet exposes you to many malicious attacks from websites. Some try to collect data on you, some want to trick you into paying them, and some want to steal your identity. So make sure your computer has an antivirus software installed, and that it is updated. 8. Letting Pets Get Too Close to the Computer If you’re a pet-owner, you probably noticed that your pets to use your computer as a pillow. Who can blame them? It’s nice and warm. You may find it adorable, but it’s actually very bad for your computer. Shed fur finds its way into the computer and can block the vents, or jam internal fans, causing the computer to overheat. So keep your furry friends away from your computer, and have it cleaned at least once a year.

9. Installing Programs Automatically You may not to read the information in the various windows during a program installation, and many programs will offer to “save you the effort” and automatically install themselves. The problem arises when these programs install add-ons unwanted toolbars on your computer, which will, at best slow it down, and at worst steal your information. Next time you install anything, take a moment to read what’s going on instead of just clicking “OK”. 10. Opening the Computer Case When it’s Still Plugged In It is recommended that you clean your computer every few months, clearing dust, fur, etc. from the case. Some of us to do it themselves, but sometimes forget to unplug the computer from the power socket. While you may think that when the computer is off, it’s safe to touch the insides, but it is not. There still is a current running inside, and touching any electrified part may short-circuit the computer and damage it, or worse – electrocute you. 11. Putting Magnets on or near the Computer Regular hard drives use a magnetic system to store data. Unshielded cables can experience magnetic interference, resulting in loss or corruption of data. Older CRT computer screens (not the LCD or LED kind) are also very susceptible to magnetic interference. What all that means is that magnets are bad for computers, so keep them away from each other. 12. Exposing the Computer to Heat Exposing your computer to direct heat s such as sunlight or heaters can cause severe damage. Electronic devices such as computers produce heat, so adding more heat can cause plastic parts to melt, as well as soldering. So make sure that you keep your computer nice and cool.

13. Hitting the Case If you hear strange noises coming from inside the computer case, when the computer behaves sluggishly or when it stops reacting, many people feel that a good thump will fix the problem. Computers are full of delicate parts, and hitting them can cause these parts to become loose, disconnect cables, and even break important parts. Next time you feel hitting your computer, take a breath, switch it off, and let it rest for a minute before starting it up. If you hear strange noises, it can mean that something has gotten loose inside, so don’t wait and take it to a technician for a checkup. 14. Not Logging out of Your E-mail When You’re Done Once you’re done with your e-mails, you should log out from the service, even in a safe place your office or home. If you don’t log off, you risk having a stranger accessing your account, exposing all of your personal information. If you need another reason, remember that you can reset your passwords via your e-mail account, so someone with access to it can access your other accounts. 15. Using Force when Connecting a USB Device USB connections are great, they made connecting devices to your computer easy, using one type of connection. We use them for flash drives, charge smartphones, connect our keyboard and mouse, etc. The shape of the USB can sometimes be a of frustration when trying to connect it the wrong way. Even if you tried 2-3 times unsuccessfully, don’t jam it in by force – doing so can break the connector in your computer, and replacing it can cost a pretty penny.

16. Opening too Many Websites at Once When I go online, I sometimes end up with multiple internet browser windows or tabs open ( my e-mail, Facebook, YouTube, etc.) but this requires that the computer allocate more res to your various windows and tabs. The computer has a finite amount of res, and when it is encumbered, it will become slow and unresponsive. Make a habit of not opening more than a total of 9 windows or tabs at any given time. Your computer will thank you.
