Internet Security - Online & Wi-Fi Protection, Technology And Science: Google to allow phone calls from Gmail
Google Inc said users of Gmail will now be able to call telephones directly from their email, putting it in direct competition with Web calling service Skype
and more traditional operators such as AT&T Inc and Verizon Communications. READ MORE BELOW...
Google Inc said users of Gmail will now be able to call telephones directly from their email, putting it in direct competition with Web calling service Skype and more traditional operators such as AT&T Inc and Verizon Communications.
While Google had already offered computer-to-computer voice and video chat services, it said that starting on Wednesday it will now allow calls to home phones and mobile phones directly from Gmail for the first time.
Google promised free calls to U.S. and Canadian phones from Gmail for the rest of this year and said it would charge low rates for calls made to other countries.
For example it said calls to Britain, France, Germany, China and Japan would be as low as 2 cents per minute.
Analysts said the service would likely be a bigger competitive threat to services like Skype's than to traditional phone companies, which have already been cutting their call prices in recent years in response to stiff competition.
"This is a risk to Skype. It's a competitor with a pretty good brand name," said Hudson Square analyst Todd Rethemeier.
Skype, which owned by private equity firms and eBay Inc and planning a $100 million initial public offering, has long allowed consumers to make calls from computers to phones. Skype became popular by first offering free computer-to-computer voice and video services.
Like Skype, Rethemeier said the Google service will likely be much more popular among U.S. consumers making international calls, than among people calling friends inside the country.
"Calling is so cheap already that I don't think it will attract a huge amount of domestic calling. It could take some of the international market," he said.
Another analyst, Steve Clement from Pacific Crest, said that anybody who is tempted by Internet calling services has likely already disconnected their home phone.
"The type of person who would use a service like that isn't the type of customer who still has a landline," Clement said.
Google said making a call through its service works like a normal phone in that a user could click on the "call phone" option in their chat buddy list in Gmail and type in the number or enter a contact's name.
Calls that cost money will be charged from an online account that users can top up with a credit card, Google said. The service will not be available for making outgoing calls on cell phones because other Google apps already cater to that market, the company added.

10 cool things to try with your tablet
Whether you received a shiny new tablet as a holiday gift or decided to treat yourself to one (and why
not), chances are you’ve figured out a few of the neat things this super slender device can do.
Oh sure, you’re already aware your new portable pal is ideal for browsing the web, reading ebooks,
watching video, viewing photos, playing games, listening to music and snapping photos -- all by tapping,
swiping and flicking with your fingertips.
But just like our brains, it’s estimated we only use about 10 percent of what our tablet can do. And so the
following are 10 additional features and apps you might not know about.
ONE - Control your home theater: Many Android tablets today, such as the
Galaxy- and Xperia-branded tablets have an integrated IR (infrared) sensor, therefore you’re able to
use your device to control your television, cable/satellite box, DVD or Blu-ray player, and more. Look for a
preinstalled “TV Remote” app to tap or download one of the many free third-party apps that can do the
same thing. Most require a one-time setup process that walks you through each component, to ensure it
can communicate with them.
TWO - Scan documents, receipts: Naturally, you don't carry around a flatbed scanner with
you to digitize documents, receipts, business cards or hand-written notes and sketches. But many apps
can turn your device into a powerful – and portable – scanner to accomplish these kinds of tasks, via the
device’s camera. Neat, huh? It gets better: the Prizmo app for iPad and Handy Scanner Free for Android
have “OCR,” or “optical character recognition,” so it’ll make the text editable and searchable, too.
THREE - Access your home computer: Your Internet-connected tablet is capable of logging
into your home computer and letting you control the experience as if you were sitting in front of your PC
or Mac. Whether you left an important document on your desktop before you left on a business trip or
want to stream a movie residing on your hard drive, you can use free apps like Splashtop Remote
Desktop (for multiple platforms) to log in securely and move the mouse via your fingertips.
FOUR - Tablet; Use it as a second monitor: Avatron's Air Display is a $9.99 app for iPad
that turns your tablet into a wireless display for your Windows PC or Mac, allowing you to extend or mirror
your computer screen. Simply prop up your tablet to the right or left of a computer monitor and your
mouse smoothly scrolls between the two screens as if it were a dual-monitor setup. Adobe Photoshop
owners, for example, might use the computer screen as the canvas and the tablet as the palette.
FIVE Use it as a phone: While you might carry around your smartphone, it might
be smarter to use a free VoIP service on your tablet to make long-distance calls. Yes, you can use your
tablet to make phone calls with free apps like ePhone, magicJack, NetTalk, Viber, and others. Make free
calls to any North American landline or mobile number, while some apps require you to register (also
free) to get an incoming number, voicemail, and more.
Access Microsoft Office files: While only a Windows tablet will give you the true Microsoft
Office experience, Android and iPad owners can still create, view and edit documents imported from
Word (word processor), Excel (spreadsheets) and PowerPoint (presentations) – with a free app like
Kingsoft Office. PDF files are also supported. All of your work can be stored locally on the tablet or
accessed from “cloud” services like Dropbox, Google Drive, and others. It’s also possible to collaborate
and share files with others. iPad owners can use Documents Free, Documents Unlimited Free or Files
App.
tablet
Wirelessly share content with a TV: If you’ve got a Smart TV, you can
probably have your Android or Windows tablet wirelessly communicate with
it. Using technology like DLNA, AllShare, Miracast or Intel WiDi – check your television’s documentation
to see what’s supported – you can do things like push media from your tablet to your big-screen TV
(photos, videos and music), enable real-time mirroring of your devices (whatever you see on your tablet
immediately shows up on your TV) or push content from your TV, such as your favorite show, to your
tablet, so you can walk away and watch and someone else can change the channel. iPad owners will need
Apple TV ($99) for mirroring.
Read free ebooks, even NYT Bestsellers: Of course you know you can
buy ebooks and audiobooks. But guess what? You can also borrow ebooks and
audiobooks, for free, from your local library – with no more late fees. As long as you have your library
card and the free OverDrive Media Console app installed on your favorite tablet, you’re in business.
To get going, you first download and install the app from your favorite app store (all four platforms are
supported) or go to the OverDrive website and click on your device of choice. Once installed, you’ll be
prompted to create an Adobe ID, if you don’t already have one, and authorize it to work with OverDrive.
Now you can borrow ebooks and audiobooks wirelessly.
Listen to 100,000 radio stations: Whether you’re into music or talk, the free TuneIn Radio
app is a “must have” for tablet owners. Access more than 100,000 radio stations from around the world –
searchable by genre, country or popularity – on an Android, iOS, Windows or BlackBerry device.
Tap into local AM/FM programming or listen to Internet-only stations, as well as hundreds of thousands of
new and archived podcasts. Browse by category, such as genre or country, add bookmarks as favorites
and play your programs in the background while you use other apps. TuneIn Radio Pro, which costs $3.99,
lets you record content to listen to later on, and offline, if desired.
iPad gesture shortcuts: Given the fact Apple’s iPad remains the no. 1 selling
tablet, the last tip is on iOS multi-touch gestures to get more done in less time. If you're inside of an app
and want to close it quickly, simply place four or five fingertips on your iPad screen and pinch inwards.
Bringing your outstretched fingers together will back you out to the home screen. Or, if you've got a few
apps open — such as a game, music and live sports score app — you can quickly view all open apps by
swiping your four or five fingers left or right on the screen.
This instantly switches to other open programs. Finally, if you're having trouble holding the iPad and
typing on its virtual keyboard at the same time, press your thumbs down on each side of the keyboard
and swipe towards the edges and it'll conveniently split your keyboard into two, making it easier for your
thumbs to reach all the letters.








'' The Year Ahead: 5 Social Media
Trends Every Entrepreneur Needs
to Know..
Technology is transforming how modern
entrepreneurs stay connected to their
business, their team and their industry. In this series,
learn more about the cutting edge tools and thinking
allowing innovators to stay ahead of the trends.
The Year Ahead: 5 Social Media Trends Every
Entrepreneur Needs to Know
Image credit: Twin Design / Shutterstock.com
The social media landscape is evolving rapidly, and
therefore, your social media marketing strategy cannot
remain static. Instead, it’s important to reevaluate
business goals, social media campaigns, platform
results and revise your strategy at least once a year -- if
not quarterly.
Being aware of trends in the social sphere can help you
design better strategies, apply the most effective tactics
and choose where to invest your staff as well
1. Diversify. You’ve probably seen headlines
about Facebook’s algorithm changes. If you currently
operate a brand or business page, one study found that
only six percent of followers currently see your posts.
Experts suggest that that number will continue to
plummet, eventually reaching one percent.
This bid by Facebook is aimed at increasing advertising
dollars. But it highlights a potential weakness in many
business’ social strategies: overdependence on any
single platform puts you at the mercy of that platform’s
whims. Whether it crashes or simply changes its rules,
too much is at stake.
--------------
2. Google+ is for real. If there’s one social
network businesses should pay specific attention to, it’s
Google+, which is already playing a more important role
in Google’s organic ranking algorithm. I expect this
trend will continue.
To the surprise of many across
theSEO industry, Google’s Matt Cutts
confirmed in a recent video that Facebook and Twitter
have no impact on SEO rankings as a result of crawling
and accessibility issues.
So it stands to reason that if Google wants to use social
signals for organic search rankings, it could easily mine
Google+ data, where its crawler access is unhindered.
Google+ is also the best way to
get access to Google Authorship,
which will play a huge role in SEO by the end of the year.
Google Authorship helps the search engine identify
your content, attribute it to the correct author and build
a portfolio for each author that may include what many
are calling “Author Rank”
-- algorithmic scoring based on author
expertise and publishing history.
In most cases, an image of the author appears next to
their content in search results, which also increases
visibility and click-through rates.
---------------------
3. Integration of social media,
SEO, and content creation. The online
marketing industry is moving away from the idea that
social media, SEO and content marketing happen in
isolation. Social media marketing decisively impacts how
content is seen and shared.
Content creation and marketing have direct implications
for your SEO performance -- especially in light of Google’
s latest algorithm updates. It’s important that you think
of the three pillars of online marketing --
SEO, content and social media -- as a system that works
synergistically to increase visibility, build your brand
and ultimately garner customers and sales.
---------------------
4. Visual content will win. An estimated
63 percent of social media comprises imagery. As such,
visual platforms are playing an increasing role in social
media for businesses. One study found that 29 percent
of Pinterest users bought an item after posting or re-
pinning it on the network.
Video content is also hotter than ever, with
the addition of networks like Vine and
Instagramfeaturing microvideos. Infographics are
another effective promotion tool for businesses with
both a bounty of data and absorbing stories to tell.
Not every platform will be right, but spending the time to
find the visual angle to your business’ story and
experimenting with different content formats can help
revitalize your social media marketing strategy.

Work.
-------------------
5. Social media as a brand builder.
Social media channels should be managed according to
a brand-oriented approach. Building your brand on any
platform impacts your SEO and improves sales over the
long term.
Are the visuals of your social media accounts consistent
with the rest of your visual branding? Is your account
name or any other copy branded?
Are you regularly filtering your status updates to ensure
they’re on-message and consistent with the overall
brand that you’re building? Focusing on building your
brand through your social interactions should be a key
focus this year.
If evolutions in social media have taught us anything so
far this year, it’s that entrepreneurs with flexible and
engaged approaches will have the highest ROI.
Take the time to understand general
trends and focus on core goals, but also
take action to experiment with specific tactics that will
grow and change as your business evolves.
What major trends are you seeing at play in social
media? Let us know in the comments below.



''TECH UPDATE!!!! Easy ways to boost your Wi-Fi range If you use a WIFI network at home, there are undoubtedly limits to where you can access the signal.
''How to Extend Your Wifi Range You might get a strong connection at the kitchen table, but take your laptop to the living room and you lose the signal.
If you're looking to boost your signal a few feet or get a strong connection all the way upstairs in the back bedroom, we've got a handful of simple tricks and more advanced techniques to get you on connected to your home wifi from anywhere in your house.
Move your router: * It's so simple, but many people don't realize that where you put your router really does make a difference. Obviously a central location is best, but for many, you are tied to putting the router where the Internet connection comes into the house.
* Beyond simple proximity, consider the router's height. The higher your router is on a shelf or cabinet, the less physical interference it's likely to encounter.
Move the router to the best possible position to take advantage of doorways and open spaces instead of walls and corners.
Wifi might move through the airwaves, but furniture, walls and appliances can weaken your signal substantially.
* Signal interference is one of the biggest culprits that might be at work if your wifi is weak. Walls and physical obstructions block your signal, but signals emitted by any electromagnetic household object do too.
Scoot your router away from anything that might interfere: cordless phones, microwaves, wireless game controllers, other wifi-enabled devices (TVs, etc.), Bluetooth devices, and even flourescent lights and elevators.
Technical tweaks: Once you've got your router in an ideal spot, take a look at your equipment. These next steps can help you further improve your wifi signal.
* Did you know routers have channels? If you live in close proximity to someone else with a wifi network you may both be trying to use the same channel and degrading your signals.
To find out if you are "crossing the streams" use WiFi Stumbler or inSSIDer to find the best and least-trafficked channel for your router to broadcast on. Once you've found the optimal channel, follow these step-by-step instructions to get your router on the right track.

How to Find Out If Someone Is Stealing
Your Wi-Fi...
If you’re doing your best to improve your Wi-Fi at home, you might
be curious about who’s using your network, and if they’re slowing it
down. It’s possible that your internet provider is just lying about the
speeds that you should really expect on your network, but it’s also
possible that there’s someone other than you (and your roommates
or family members) using your Wi-Fi network..
Perhaps the worst part of someone
stealing your Wi-Fi is that they’re slowing down your
network. If there are already multiple phones, tablets, and
computers in your household, chances are good that your
bandwidth is divided up enough already.
The best way to resolve the question is
to use one of a few simple tools to take a
look at what’s going on with your
network. You can check whether the devices that are
connected to it are ones you recognize, or ones that look
suspicious and can’t be accounted for when you take stock of the
Wi-Fi-connected gadgets in your home. Depending on your level of
interest and your technical ability, there are some simple ways to
find out.
How to Find Out If Someone Is Stealing
Your Wi-Fi
Check your router’s administrative page..
One way to see what devices are connected to your Wi-Fi network
(and to check whether you recognize all of them) is to log on to
your router’s administrative page and check its DHCP Client Table,
DHCP Client List, or the list of Attached Devices.
From there, you’ll be able to see all of the computers,
smartphones, tablets, and any other devices connected to your
wireless router
The website of your router’s manufacturer (or
the print manual that’s been collecting dust since you purchased
the router) should include instructions on how to log in to your
router. Biersdorfer notes that that usually requires typing the
router’s Internet Protocol (IP) address into your web browser, and
logging into the page with the administrator name and password.
You can also find your router’s IP address
using text-based commands on either a Windows
machine or a Mac. For instance, PC users can type “cmd” in the
Start menu’s Search box, open the Command Prompt () program,
and enter “ipconfig” to find the router’s address, which Windows
calls the Default Gateway.
Or, Mac users can find the router’s IP address by opening the
System Preferences icon, clicking the Network icon, and looking at
the number that’s listed next to “Router.”
How to Find Out If Someone Is Stealing
Your Wi-Fi
If you don’t want to bother with logging in to your router’s
administrative page, you can download an app that will do the dirty
work for you. There are a number of apps that will scan your
network for connected devices. In fact, your router’s manufacturer
may have its own app,
Or, if you don’t like the manufacturer’s software or prefer to find
another option, there are plenty of programs from third-party
developers, apps that are equally capable of lending a bit of clarity
to the assortment of devices that are connected to your network
How to Find Out If Someone Is Stealing Your
Wi-Fi
If the list is confusing and the device names difficult to parse, you
can turn off each of your gadgets or disable their Wi-Fi in turn to
figure out their names. It’s possible that all of the devices on the
list will be accounted for.
But if you find a device connected to the network that doesn’t
belong to you, you know that someone else is using your Wi-Fi. It’s
possible that the unauthorized user is connecting to your network
only sporadically, so you may need to perform checks a few times to
determine if the device is responsible for slowing down your Wi-Fi.
There are some other straightforward
ways to improve your Wi-Fi’s
performance. For instance, you can evaluate whether the
placement of your router is ideal (and move the router if it’s not).
You can make sure that you’re actually using your router’s dual-
band functionality.
You can determine whether there are any devices you can connect
via an ethernet cable instead of Wi-Fi. Or, you can replace your
router’s stock antenna, or upgrade to a new router altogether. But
if those tips don’t solve the problem, you may want to get in touch
with your internet provider and see if there’s a problem that the
company can help you resolve.
if you have suspicions about who’s
using your network, or if you’ve noticed that there are
more devices connected than you and your household can account
for, then you should consider changing your network’s password.
That way, somebody who’s logged in using your old, easy-to-guess
password will immediately be logged off your network.

'' Anti- Virus Software''
Anyone with a computer these days needs antivirus
software. Unless your computer never connects to the
internet or any external drives like USBs or external hard
disks - you're going to need a good and reliable antivirus
program to protect you against malicious attacks.
There is only so much you can do yourself to protect your
files and identity against potential threats. Internet access
has changed the way viruses are spread these days and it
is no longer enough to simply avoid suspicious downloads
from unknown sources.
By simply being connected to the internet, your personal
information and files are vulnerable to possible attacks and
that's where antivirus programs come in.
What is Antivirus Software?
Antivirus software is a term used to describe any security
suite that protects your files against viruses, trojans,
worms, and other malware.
These days, the best antivirus software products offer
much more than simple virus protection, and extend their
security to online protection against phishing and identity
theft and anti spam.
The basic antivirus product works in the background on
your computer, scanning existing files and files you have
just downloaded to determine whether they are safe or not.
If a computer virus is detected, an antivirus program will
either delete it or quarantine it, depending on the settings
and the type of virus detected.
While the end goal of all antivirus products is the same, the
methods used to detect and stop attacks differs depending
on the technology used by each security company.



How To Clear Your Google Search History?
Google knows a lot about you and it should not surprise you to know that everything you say to Google is recorded and kept in a database. However, if you are
privacy-conscious enough, you can listen to all of it and delete what you want.
In June 2016, Google launched a new portal for all user account-related activities, from where you can manage your privacy settings and see what you have
searched for. Here is how to find and delete the recordings of your voice searches.
Log into history.google.com
Go to “Activity Control” on the left side of the screen
Go to “Voice & Audio Activity”
Scroll through the list to see everything you have searched for using your voice
Check the boxes next to the recordings you want to delete (you can only check one box at a time)
Click on "Delete" to complete the process
Voice searches are far from the only thing Google saves about its users. All of your search history is saved as well, and if you want to delete that as well, here is
how.
Go to Google's history page
Click on menu (the three vertical dots) and then hit "Activity Controls"
Go to "Web & App Activity" and click on "Delete" to complete the process
Similarly, you can go and delete your location history, device information and YouTube search history.
-----------
If you want to stop Google tracking your searches for good, head to the activity controls page and toggle tracking off. However, turning off tracking doesn’t
mean Google will stop recording what you say to it or storing what you search for. It only means the data will be saved anonymously instead of being linked to
your account.
--------------
Google claims it stores users’ searches to make ads more relevant and to improve the search feature. If this storage of your internet data makes you feel like
your privacy is violated, the only option you have is to not use Google’s services.
But if you think it’s illegal for Google to store your data, you would be wrong. When using its services, you agree to allow Google saving your data. Read
Google’s Privacy Policy here to understand how and under what circumstances Google can share your information.

Wireless (Wi-Fi) networks...
A Wireless network basically utilizes the wireless
frequencies (2.4 Ghz or 5 Ghz spectrum) to transmit the
data, voice and video from one point to another using
the wireless signals as the medium –
But it is very rare to have a total stand-alone wireless
network as the wireless transmission and reception is
restricted from the client (PC/Laptop/Wi-Fi Phone etc) to
the Wireless Access Point.
Beyond that, the data is carried in the wired backbone
network.
===========
What are the wireless standards for Wi-Fi ?
IEEE (Institute for Electrical and Electronic Engineers)
have drafted certain standards for wireless equipments
and each equipment needs to support one of them or
multiples of them so that they can inter operate with
wireless equipments made by other vendors. The
different standards are:
IEEE 802.11 b – This was a very early standard and
supports a maximum throughput of 11 Mbps and
operates in the 2.4 Ghz spectrum...
=====
IEEE 802.11 a – This is a more recent standard supporting
a maximum throughput of 54 Mbps and operates in the 5
Ghz spectrum
IEEE 802.11 g – This is the most common standard
supporting a maximum throughput of 54 Mbps and
operates in the 2.4 Ghz spectrum – Almost every laptop
and access point should support this.
IEEE 802.11 n – This is the latest standard supporting a
maximum throughput of 300 Mbps now and operates in
both 2.4 Ghz as well as 5 Ghz spectrum’s.
Note: You cannot get the higher throughput offered by
802.11 n technology by just replacing the older access
points with the newer access points – you need to
replace the client adaptors to support 802.11n as well
and you need to upgrade the backbone wired network to
support 1000 Mbps throughput instead of the earlier 100
Mbps.
Everything you need to know
about Wi-Fi calling
Curious about Wi-Fi calling and what it entails?
Here's the rundown on what you need to know.
Making a Wi-Fi call on a smartphone is nothing
new. The ability to patch a call using a Wi-Fi
connection instead of a cellular one has been
around for years, with Skype being one of oldest
and most popular apps to do so.
But just as carrier technology continues to evolve,
so does Wi-Fi calling. In addition to more
third-party apps popping up to take on Skype (like
the Facebook-owned WhatsApp and Messenger),
phone makers themselves are taking on Wi-Fi
calling with native apps, including Apple iOS'
FaceTime and Google Android's Duo.
==========
There are also phone networks that prioritize Wi-Fi
calling first, like Google's Project Fi and Republic
Wireless, which offer customers cheaper
alternatives to regular phone plans.
To compete with this, legacy carriers that use
traditional cellular technology have adopted Wi-Fi
calling too..
=======
What exactly is Wi-Fi calling?
Instead of using your carrier's network connection,
your phone can make a voice call via a Wi-Fi
network. This is the same Wi-Fi connection you
have set up at home, or whatever Wi-Fi hotspot
you happen to be on when you're out and about,
such as at a cafe or library. In most ways, it's like
any other phone call, and you still use regular
phone numbers..
=========
Isn't that what Skype does?
In a way, yes. There are various services including
Skype, WhatsApp, Messenger and Viber that
provide what's known under the umbrella term
VoIP, for "voice over Internet Protocol," to make
calls with either a Wi-Fi or data connection.
Carrier-branded Wi-Fi calling is slightly different,
however. It's baked directly into the phone's
dialer, so you don't need to fire up an app or
connect to a service to use it.
Wireless LAN
A wireless local area network is a wireless computer
network that links two or more devices using wireless
communication within a limited area such as a home,
school, computer laboratory, or office building.
This gives users the ability to move around within a local
coverage area and yet still be connected to the network.
Through a gateway, a WLAN can also provide a
connection to the wider Internet..
