What exactly is the 802.11 Standard?

by Leave a Comment

The following article tries to throw some light on what is the 802.11 standard for wireless networks.

What exactly is the 802.11 standard?

IEEE 802.11 technology is a set of specifications related to the physical layer & media access control (MAC) for implementing wireless LAN in certain frequency bandwidths. They are created by Institute of Electrical and Electronics Engineers LAN/MAN Standards Committee. The base version was released in 1997 and has amendments made to it thereafter. With every amendment, an alphabet is suffixed to show the improvements made which would be defined in the standards.




What is Wi-Fi?

As the general misconception goes Wi-Fi does not stand for Wireless Fidelity. The term was coined by a brand-consulting firm called Interbrand Corporation. The name, then became, Wi-Fi standard which was a little more easier to remember for a common man when compared with IEEE 802.11b Direct Sequence.

Wi-Fi can be generally less secure than the regular Ethernet (wired) connections as there is no physical connectivity required. These days Smart phones, laptops, game consoles, TVs can connect wirelessly to the WiFi modems.

The following websites provide more rich information related to the WiFi concepts:

Samsung launches Galaxy S5 In India – New Delhi – Price Range and First Impression

by Leave a Comment

Samsung Electronics launched its yet another gear and Galaxy Smart phone series, Samsung Galaxy S5 Smart phone in New Delhi on Thursday, March 27th for the domestic market.



First Look and Impression

This seems to be available to general public from April 11, 2014. Its features have some really advanced technical capabilities and the price range which is not yet confirmed varies between Rs. 51,000 and Rs. 53,000.


This latest shot from Samsung in its smart phone series is expected to have good demand in the Indian market as there are too many players in the market these days with Samsung leading it. High prices don’t seem to affect the mobile manufacturers who are willing to risk placing these high-end mobiles in the range of half a lakh Rupees, who are confident that people buy for quality and pay regardless, even if the prices are close to the cost of a decent laptop.

Key Features

The features of the new Samsung Galaxy S5 include being a sand (dust) and water proof phone (with IP67 certification), which was a major drawback with its predecessors S3, for example. A couple of my friends’ S3 were damaged after it contacted with rain. Hope the S5 addresses this water proof thing well. The glossy plastic cover is also a thing of past with this new release. Instead, it comes with a plastic soft touch back cover with a small dotted pattern. It has round edges with a relatively low weight when compared to its predecessors, S3 & S4.

Other key features include a whopping 16MP rear camera, a better battery life, 16GB memory expandable upto 128 GB, 2.1 MP front camera, WiFi port, GPS, Bluetooth, Infrared, 2GB RAM, Android 4.4.2, fingerprint scanner, a perforated pattern on its back cover, and is offered in four different colors – copper gold, electric blue, shimmery white and charcoal black. It has a bio-metric screen locking feature. This phone comes with a USB 3.0 port covered with a flap. As per sources, the Indian version is powered by Exynos processor, four A15 cores – running at 1.9GHz that helps in high performance and gaming. It also has four low-power A7 cores that run at 1.3GHz. The phone is of impressive design overall and is good to use. This phone weighs close to just 145gms, with the screen size of 5.10 in inches. This phone has one Nano Sim slot.

Some of the Pre-loaded Google features and apps include, Google Drive, Google Chrome, Gmail, Hangouts, Maps, Play Books, Music, Store, Newsstand, YouTube

What is bio-metric screen locking?

 Bio-metric screen locking is a security feature enabled in Smart Phones to cater to mobile security, screen locking based on an individual’s birth marks like fingerprints. This enables one to use it to lock a phone securely, conduct e-commerce safely like purchasing and paying through PayPal online payments with the credit card reader, etc. This reader also helps with other health related apps. This phone also comes with a health rate monitor.

Power boosting capabilities

With the research and development heading to a glory of matching up with a common man’s expectations, this phone comes with some decent power boosting capabilities. This Samsung Galaxy S5 has an ultra power boosting functionality where the user can enable it to save some last left batter to use his phone, when it was forgotten to charge it with the mobile charger. What this does is that it makes the phone go in to black and white mode, shuts down the phones key functions, and dims the phone allowing the user to make use of the last left battery power, until its charged again. Quite nice human-tech intervention here.

Gear-Fit

The gear fit with its plastic cum rubber make is really elegant, cool and light-weight like its phone partner S5 – with a 1.8 inch screen. This helps in tracking the physical activity of its wearer, like foot steps taken during a morning walk or jogging sessions. It can also show notifications like calls, messages.

How To Block Ads (in your blog) From Specific Websites – Google AdSense Trick

by Leave a Comment

Blocking certain ads from displaying on your website will not only help in avoiding those ads on your website, but will also ultimately help in increasing your income. The reason is that not all ads are interest based. Some ads show up as back up when Google cannot find relevant keywords in your blog post. That’s when some common ads are shown instead of relevant ones.



The maximum number of ads that can be blocked per one AdSense account is 500. This can be at the site level or the account level – either ways, the upper limit is 500.

How to block:

Go to AdSense account > Allow & block ads section.

On the left side – under the Content menu – select your site. On the right side, under Advertiser URLs, type in the URL that you want to block. Hit on Block URLs. This will ensure that ads from that particular advertiser will not appear on that site which you selected.

If you want to block ads at the account level – which means that ads from that URL will not appear on any of your sites within AdSense account – select All my sites under the Content menu on the left side and simply enter the URLs under your Advertiser URLs. This will ensure the ads from that blocked URL will not appear on any of the sites included in your AdSense account.

Remember, do not click directly on the ads to find out the URLs. Instead of creating such invalid clicks which is against AdSense Program Policies, you can just find out by using Google Publisher Toolbar – which is available from the Chrome Extensions page here.

How to keep the paragraph settings as default in Microsoft Word 2007

by Leave a Comment

When typing in a word document you may notice that by default the line spacing is either 1.5 lines or 2 which is quite irritating while editing a normal, personal word document – nothing official.

Word line spacing defaults - thekeyponderer.blogspot.com

When we navigate to the Home > Paragraph > Spacing section – you can see that the ‘After’ field is 10pt by default. You will have to change it to ‘0’ (zero) so the spacing is minimal. But this setting has to be made everytime.

So how to make this setting with zero line spacing as default?

In the same window, there is button that reads ‘Default…’. Just click on it to make your current changed settings as default. That’s it!

To change this default to normal or any other setting – simply make your changes and click on ‘Default…’ button again to keep the new settings as your default.

Note that this change only works for the current document. If you open a new document, then the changed settings won’t apply.

Please do write your comments below if you liked this post. Thank you!

Facebook in its entirety being useful or not, is not the case of concern. But few keyboard shortcuts are certainly useful to save some time when using Facebook.
This is really funny here because there are some organizations that scream at their employees of low productivity and wasting time in Facebook. And here we are talking about saving time while using Facebook – however funny it might be, it certainly is true when you use keyboard shortcuts to get some things done within facebook.
With these keyboard shortcuts you can essentially speed up your pace at which you update your status, timelines, profile, check your friend requests, etc.

Keyboard and Browser types

If the computer you use doesn’t have a numerical keyboard – a separate num keypad, then the keys you press should be used by hitting the ‘shift’ key when pressing shortcuts that have numbers in it. When you use Internet Explorer, with every key press, hit the Enter key for shortcut to work. It’s that simple! (Pun intended).
