Everything you need to know about Smart TVs

Think of a smart TV as a connected TV – a TV screen that is consistently connected to the internet. They run a heavier OS then standard HD TVs and are capable of streaming video, music and other stuff from other services

The tech world is always changing; as TVs are the primary entertainment electronics for most of us. Technology powering the TVs is also getting better day by day. Starting from grayscale then flat screen, High Definition, Full HD, UHD (ultra-high definition) and smart TVs – the makers are always trying to make something better than the previous one. Let’s get to the point.

What are Smart TVs?

 

Think of a smart TV as a connected TV – a TV screen that is consistently connected to the internet. They run a heavier OS than standard HD TVs and are capable of streaming video, music and other stuff from other services; they include a web browser and also sometimes the ability to install apps. Some more expensive TVs may offer you a camera for video chat. A smart TV may use Wired or Wi-Fi based technology to connect to internet. Though as the features sound exciting the prize is not so. A Smart TV is much more heavier on Pocket then a normal HDTV.

The Bad side…

Makers such as LG, Sony and Samsung make these TVs – Who care more about hardware and are not so good about software, and there is one more thing to care about – when we buy TV we think of keeping it for 4-5 years but you will want to buy a new smart TV in just 2-3 years the reason: makers don’t provide updates regularly OOUCH…

A smart TV tries to do too much but is not successful in anything.  A computer connected to internet can stream technically anything from any service while in smart TV the streaming relies on the manufacturer’s mood – you can’t use Netflix unless there is an app available for the TV. And believe us there is not every streaming service app available for Smart TVs. Also using web browser by a remote is really uncool.

Buy / don’t buy?

Smart TV sounds like a cool idea, a connected media rich experience – But it comes at a prize. The price is sometimes too much for any user. You can easily buy a normal LCD TV and add a PC or any other device to stream stuff from the internet.

You can buy a smart TV if you do not care too much about money and you are not willing to set up other products with your TV. If you want to save bucks there are some other options to think of.

The Alternatives:

Media Streaming Sticks : These are the cheapest alternatives and they are the smallest too. Google Chromecast is a perfect example, it is only $35 and can stream media from your smartphone, tablet and even chrome browser. Amazon fire Stick and Roku are also quite good options to choose from. They don’t come with remote control – you can control them using your phones.

 

Everything you need to know about Smart TVs

Separate Media Players : there are many media players available on the market and they have much better functionality too. The Apple made iTV and Google Nexus Media Player are just to name few. You can use them to stream content from your home network and even NAS. Media Players are not so large and work perfectly as media steamers – heck! you can even play games on some of them.

Gaming Consoles : An Xbox or PS4 is always a better option then buying a so-called Smart TV. You can stream media and even browser the web -plus play games on them too. They also have built in Optical drives, You can use them to watch Blu-Ray Disks.

Add  a PC : Adding a full PC is always an good option to think of – you can set up DVR and stream anything form web – HTPCs are more expensive but they have much more value then a Smart TV.

What is RAID: Explaining the Tech

RAID stands for Redundant array of inexpensive or independent disk. Actually it is a technology by which we can use more than one physical hard drive simultaneously to get better performance and Data redundancy.

RAID stands for Redundant array of inexpensive or independent disk. Actually it is a technology by which we can use more than one physical hard drive simultaneously to get better performance and Data redundancy.
Any user can just plug any number of hard disk in his computer and use them but using a technology like RAID increases the performance and stability of your system.
An SSD is always the fastest solution of data storage but it is not as much secure as some of RAIDs.

Based on the technique of Implementation there are many kinds of RAID available. we have shortlisted some of the most important types of RAID

What is raid?
RAIDs are mostly used in Servers

RAID 0

In this type of RAID all the data is distributed into each disk equally, Confused? Lets simplify it imagine a file, now distribute it into 4 parts, now imagine 2 RAID disks now write data part 1 in drive A , data part 2 into drive B , next Data part 3 into drive A and at last data part 4 into disk B. now writing speed and reading speed will be much more faster, but this performance will come with a risk, if any disk fails all the data will be lost.

RAID 1

It is really simple, it consists of a mirroring. All the data is written into both disks, it increases the writing time but the reading time is decreased. If any disk fails user need not to be worried. All the data can simply be recovered from other volume. In this RAID system the highest reading speed is limited by fastest Disk in RAID whereas writing speed is limited by the slowest Disk in system. There is one more drawback the total size of RAID volume will not be the sum of each disk size but it will be equal to the size of smallest disk.

RAID 5

This technique is a lot complex than the above methods, it requires at least 3 disks to create RAID of this kind. This technology uses block level stripping in the disks and in distributed parity (which means the data that can be used to recover data) .It provides protection against data loss and also slightly improves the performance. In this type of RAID if any disk fails the data is recovered from the distributed data. As this it requires 3 or more disks it us normally used in high performance servers.

 RAID 6

Last but not the least ,RAID 6 uses double distributed parity in block level striping. The major difference between RAID 5 and RAID 6 is that it can withstand the data loss up to two physical disks. That means even if two disks are damaged the data can be restored. If you want to create a RAID with a lot of disks, RAID 6 is really useful.

Which RAID should anyone use? The correct RAID type is based on the use and needs. Simply put, if you need pure performance and you don’t care about data recovery than you can go with RAID 0. If you are not so high on budget but data loss protection is your primary need you should use RAID 1. And if you are going to make a high performance server or NAS then you can use RAID 5 or RAID 6. Although there are other RAID types available. In this article we have only discussed the most widely used standards. Anyone should do his homework about RAID types first before using any kind of RAID system.

GETTING RAID: As RAID can be implemented by using 2 or more disks. There are 2 ways to make it possible :

RAID BY USING SOFTWARE

Modern age software can be used to make a RAID system in a PC. Windows servers support RAID 0 , 1 and 5 where as Windows 8 has introduced a new feature called storage spaces. Apple’s MAC OS X supports RAID 0 and RAID 1.

 RAID BY USING HARDWARE

Any computer user can implement RAID by using a RAID controller. These are supplied with proper drivers and firmware.

Difference between JPG, PNG and other Image Formats

We are here with an interesting infographic that will help you in understanding different image formats and their Plus and minus points.

Computer files are usually stored with a file type such us most of the time music files are found in MP3 extensions and Microsoft Word Files have a DOCX at the end of their name. Images, just like music and video formats are found in various types and some of the most popular are JPG (or JPEG) PNG, GIF and BMP. To show a normal selfie you can use any of these format and all of them will work for standard photos. However not all people know that each of these image format is a lot different than the other and each of these has their own pros and cons.

Different Image Formats

Starting with the BMP format –at past used as default format for Microsoft’s really old Paint –it is the heaviest on size and does not support transparency.

Moving on to the next image format JPG (or JPEG). it is most efficient on file size, it is weaker in terms of image quality.

The PNG or Portable Network Graphics is good replacement for JPG, it also supports alpha channels, still it will cost a bit more then JPG when it comes to file size.

Getting next to GIF, the new craze in social media. It is older that what you may think and GIF supports both transparency and Frame switching.

We are here with an interesting infographic that will help you in understanding different image formats and their Plus and minus points. At the end of the day you will get to know which image format should you use to store Birthday photos of your son and which to use as logo on your website.
