With the influx of Technology in almost every sphere of our
lives, most of us claim to be tech-savvy. We text message in the blink of an
eye, use Bluetooth while driving, and debug programs in a jiffy. However, many
of us may not have a clear concept about each and every ‘bit and byte’ of the
tech world.
Here is a list of the Top 10 Tech concepts that you should
have learnt.
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 (LANs). To set up a Wi-Fi network, the main computer acts as a
server with a wireless network 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.
