Top 10 Technology Concepts

 

10. Windows Registry

The Windows Registry is a hierarchical database that stores the configuration settings of the operating system as well as application software that are installed in your PC. It is simply a database that stores your computer hardware, software, user settings, security and property settings for folders and programs. It is an important part place in the Windows OS, where most of the apps are stored.

9. SSL Encryption/HTTPs

HTTPs stands for Hypertext Transfer Protocol Secure and is a URL scheme that is in sync with the normal HTTP connections, but has an additional signal that secures the browser with an encryption layer of SSL/LS to protect the traffic.
It is a combination of HTTP and SSL/TLS protocols to provide encrypted communication and secure identification of a web server. The SSL encryptions are usually used for payment transactions or sensitive corporate information that passes through the World Wide Web.

8. Network Neutrality

As the name suggests, Net Neutrality is all about creating a neutral Internet. It is also known as Internet neutrality or Network Neutrality. According to this concept, Internet traffic should be treated equally. The term also supports the view that Internet should be an open platform, just like any other home utility, as it has now become a necessary part of our daily lives.
Net Neutrality believes in no restrictions by the Internet Service Providers (ISPs) and governments on sites, content and the types of commodities that are attached to the modes of communication.

7. 4G

4G is the fourth generation of wireless cellular standards in telecommunications. The peak speed requirements for 3G service is 100 Mbit/s for high mobility communication and 1Gbit/s for low mobility communication.A 4G system provides a secure mobile broadband solution to smartphones, wireless modems and laptops. Internet access, IP telephony, gaming services and multimedia streaming services are all provided by the 4G system. Technologies such as WiMAX and LTE are 4G technologies.

6. Lossless and Lossy Music

Usually, audio compression comes in two forms-lossless compression and lossy compression. In the lossless audio format, the audio files retain every bit of information that is found in the original so that nothing is lost.
The lossy format is the audio compression that loses some of the information found in the original, especially when you are compressing the file to make it smaller. The MP3 format is the lossy compression format. Here the very high and the very low frequencies are often skipped during compression.

5. 32-Bit and 64-Bit Operating Systems

The terms 32-bit and 64-bit imply the way a computer’s CPU handles information. The 64-bit version of the operating system can handle huge amounts of RAM and more effectively than the 32-bit operating system. For the 64-bit version to be installed, your computer needs a processor that is capable of running a 64-bit version of the Windows OS. The main advantage of the 64-bit is that it is more responsive when you are running several programs at the same time.

4. Android Task Killers

Android Task killers were earlier considered very useful tools. They could improve your phone’s performance and boost battery life. However, they are no longer used, as they do more harm than good to your Android phones.
A task killer is an app from which you can force other apps to quit, providing more space on your Android OS for other apps to work speedily. It is advisable that you don’t use them unless you know perfectly well how they function.

3. Proper Windows maintenance

To keep your computer running smoothly you should know how to maintain, restore and have a back up of your registry. Improper entries in the registry can destroy the whole Windows operating system.
For proper Windows maintenance, see that you have a back up of your registry before editing it. Then you need to clean up your registry as it may be filled with cluttered unwanted programs. The other aspect of Windows maintenance is to fix a damaged registry as this will restore something that has been inadvertently damaged.

2. Spyware, Viruses, Trojans, Worms and other Malware

Viruses, trojans and worms are all a sort of malicious software programs that are designed to disrupt your computer operations or gather information through unauthorized access to system resources. There are thousands of viruses, Trojans, worms, bots and root kits all stalking out there waiting to infest your computer. It therefore makes sense to have a very good antivirus software package installed to combat with this menace.

1. Wi-Fi and Wireless Internet

Wi-Fi is a wireless communication standard that is used between computer devices to share resources and data. The Wi-Fi signals cannot travel a long distance and are therefore used for Local Area networks.
To set up a Wi-Fi network, the main computer acts as a server with  interface card. This card features a small antenna that receives and broadcast WiFi signals. A high speed modem assists the direction of the traffic with the help of a router and a switch, to integrate wireless internet into the WiFi LAN. Now any computer in the vicinity can make use of the WiFi signals and connect to the Internet using the WiFi Network interface card. Smartphones, Mobiles, PDAs and laptops have a built-in Wi-Fi ability that enables them to surf the Internet, access or transfer data with speed and efficiency.
These are some of the technology concepts that one should know as they may come handy at some time or the other. With the vast trove of technology terms, sometimes a lifetime may not be enough to learn all of them.

3rd & 4th Generation mobile networks

Definition of "3G"

3G, or Third Generation, is a somewhat generic term for network technologies that the ITU classifies as part of their IMT-2000 specification. Generally, wireless network technologies must be able to provide a mobile device with a downlink connection speed of 384kbps in order to be considered a 3G technology. The most used 3G technologies are WCDMA, CDMA 1xEV-DO, and, technically, EDGE and CDMA 1xRTT.

Definition of "4G"

4G is the term used to refer to the next wave of high-speed mobile technologies that will be used to replace current 3G networks. The two top contenders are LTE and WiMAX, both of which are IP based networks that are built from similar, yet incompatible, technologies. Sprint and Clearwire are currently offering 4G WiMAX service in the USA, while Verizon and AT&T have committed to the use of LTE and are trialing their own 4G networks

"A2DP"

Definition of "A2DP"

The Advanced Audio Distribution Profile is a Bluetooth profile that allows for the wireless transmission of stereo audio from an A2DP source (typically a phone or computer) to an A2DP receiver (a set of Bluetooth headphones or stereo system). Such devices typically also support the AVRCP profile as well in order to allow for track selection and such. A common misconception is that A2DP support is available on all Bluetooth 2.0 devices,which is not the case, and that A2DP is only available on Bluetooth 2.0 devices, which is also not true. A2DP support can exist in older versions of Bluetooth, it just was not commonly supported.

Wink allows you to create photostrips with 3 photos, 4-photos or 5 photos. You can send a printed photostrip anywhere in the world for $2.50.


Instagram

The rise in popularity of Instagram has been amazing. As of May 16, 2011, the official iTunes page reports that there over 3.75 million Instagram users around the world.

The fast rise of Instagram has been fueled by being an official tool by the National Public Radio (NPR) for photo distribution, a favorite iPhone app from Jack Dorsey (Twitter founder and Instagram investor) and Phil Schiller (Apple marketing guru), and a way to share photos by Korean pop stars and gangsta rappers such as Snoop Dogg.

Flickr

If the Shutterfly team was able to come up with an iPhone app, the Flickr team (acquired by Yahoo!) had to come up with one as well. According to the app developers at the official iTunes page of the Flickr iPhone app , the app allows you to:
Shoot, upload and share photos & videos: Geo-tag your photos or add them to a set. View your photos by set and tag.
Stay up to date: See recent photo activities from your friends and family. Search and view photos by contact. Make comments or mark them as favorites.
