Difference Between LTE and VoLTE explained

Whats the Difference Between LTE and VoLTE?? 

We have entered a new era in the mobile Internet. This is the transition time from 3G to 4G Internet. And there is a lot of buzz around the free voice calling and free unlimited 4G Internet offer made by Reliance Jio. people have been asking questions if their phone supports 4G and also what is the difference between LTE and VoLTE. In this article, we will learn why people are asking about the terms like LTE and VoLTE. We will also learn how these two technologies are different from each other and which one is better.

WHAT IS LTE?

LTE is a mobile Internet technology standard. 

It’s an abbreviation of Long Term Evolution. You may wonder why LTE keeps popping up in context of 4G. Well, 4G (or fourth generation) is just a common name given to LTE technology.

LTE supports download speed of 100 MBits per second and upload speed of 50 MBits per second. Another variant of LTE, called LTE-Advanced, supports download speed of 1 GBits per second and upload speed of 500 MBits per second.

 LTE is fast becoming available across the globe and mobile Internet Service Providers are upgrading their networks from 3G to 4G. LTE is at present the fastest data transfer technology and soon it may become the most dominant among all the mobile Internet technologies being used.

WHAT IS VOLTE?

The full form of VOLTE is Voice over Long Term Evolution.

VoLTE is a technology wherein you can simultaneously send voice and data over the network without diminishing quality of voice. In case of LTE, if you make a voice call and you also keep your data connection on, the quality of voice will reduce.This specifies that if you have to make a voice call,you have to switch off data.

In the cases of 2G & 3G you may have noticed that the phones will automatically stop data transfer so as to preserve the voice quality.

But in case of VoLTE, the voice quality will not reduce even if your data connection is on

What are the Benefits of VoLTE over LTE?

1. Voice quality is better in VoLTE.
2. You can keep data connection on while making a voice call.
3. VoLTE can connect calls faster
4. 4G VoLTE works on higher frequencies like 800 MHz and thus it can make connections much farther away from the mobile phone tower. In previous technologies, it was sometimes difficult to find a mobile signal.
5. Use of VoLTE may save phone’s battery.
6. VoLTE allows to you make video calls without using any third party apps.

                

What is the Difference Between LTE and VoLTE?

	LTE	VOLTE

2.	Primarily designed to be a data-only technology	Designed to carry both voice and data
3.	Does not natively support voice transmission.	Supports voice as well as data transmission.
4.	Quality of voice reduces if data connection is left on.	Voice quality remains excellent even if the data connection is on

Why "C" is the Default Drive Letter?

Why is "C" the default Hard Drive Letter in so many Computers?

Let us understand this fact in an simplest way,

If you are using a windows computer or a windows operating system,then head to the My Computer section by double clicking the My Computer icon from the desktop.

A windows which looks like in the following image will appear :-

Here, in the above image we can see The Drives in our computer and its size,we can also see the Drive letters assigned separately to each drive which is different from each one.

Here the drives shown are C,E,G,and I. 

where the C drive contains all the files related to operating system or application software's installed or saved.

Why is that? Why is ‘C’ the default drive letter – rather than ‘A’, which would make more sense intuitively – on so many computers? As it turns out, there is an interesting reason behind this C domination…

About History-

You might be a bit surprised to know that the hard disk drives, which are installed inside computers these days, and act as the basic storage units.Although hard disks have been around since the 1950's, they were not a standard/essential part of the computer system due to their high cost.

Floppy Disks-

Most standard floppy disks (like 5 1/4″, 3 ½” variants) could not store more than 1 MB’s worth of data.Therefore, it’s not surprising how quickly floppy disks were replaced by compact discs, and eventually became completely obsolete,If you were using floppy disks instead of a disc, it would take no less than 3,711 floppy disks to install Windows 8.1 on your computer!

Now coming back to our topic-

The floppy disk drives in computers using MS-DOS or certain other operating systems were labelled as ‘A’. After that eventually certain technological improvements were made and the new systems came with two such floppy disk drives, providing even more storage capacity.

This new drive was labelled as "B". No other disks were added ,so these two disks were labelled as "A" & "B" for floppy disk drives.

How Hard Disks evolved?

during that time when hard disk drives were evolved, they were far too expensive to be added to every computer.

hard disk drives grew more affordable and became a standard component in most computers by the late 1980s. Now, these new systems consisted of both floppy disk drives (A and B), as well as a hard disk drive. Labeling this new member as ‘C’ was the logical thing to do. 

Hence time went on,many new advancements came to existence and slowly The use of Floppy Disks came to an End. 

Floppy disk drives were entirely removed from computers, but somehow the label ‘C’ stuck with hard disk drives.

In fact, most Windows computers come with the first partition labelled as ‘Local Disk C:’ for that same reason. Of course, these labels are not set in stone. You can easily change them with a few clicks on your computer, provided you’re using an Administrator account. 

But many people ignore doing that.

        

Difference Between Intel core i5 and i7 Processors

Which CPU Should You Buy? Comparing Intel Core i5 vs. i7 Processors.

Two of the CPUs most often in contention are the Intel Core i5 and Intel Core i7. For many consumers who are on the hunt for a new desktop or laptop PC, one of the biggest considerations is the type of Processors.

Intel’s Core i5 and i7 processors are fast, more power efficient, and better equipped for modern computing than any others on the market. The i5s and i7s have made their way into a huge number of laptops and desktops. Like most computer components, there are dozens of models at each tier to choose from, and it can get a little overwhelming.er

It’s worth noting, before we get started, that we’re talking specifically about Intel’s sixth-generation Skylake chips here. A lot of the information applies elsewhere, but the newer chips tend to provide noticeable feature and performance improvements over previous generations. You won’t save a lot of money buying Haswell chips either, and all but the most experienced builders will want to stay away from the early Core i5 and Core i7 offerings.

Hyper-Threading

Hyper-Threading means that each core on the processor is capable of handling two processing threads instead of just one. These “threads” are used by software to manage multiple tasks simultaneously, rather than queuing everything up for execution one-by-one.

Hyper-Threading is not typically found on Core i5 desktop chips. It is common on Core i5 mobile dual-core processors. All Core i7 processors have it, which means they all can handle twice as many threads as they have cores. While nice to have, the feature’s impact is very dependent on software. Only applications specifically designed to take advantage of multiple threads will see a performance increase. The feature is most useful to people who run productivity applications, including photo and video editors.

Clock speed 

The clock speed is a measure of how quickly each core on a processor can handle operations, generally speaking. It has become less relevant as a general performance indicator over the last decade because different processors handle operations at a different rate even when they have the same clock speed — but we’re comparing just Core i5 and i7 processors here. They’re built on the same architecture, so a higher clock speed means better performance.

In addition, Intel Core i5 and i7 processors are equipped with a feature called Turbo Boost. Turbo Boost will increase your clock speed when power use is low otherwise, or some of the cores are sitting idle. This can boost performance in certain situations. Quads tend to boost more aggressively than dual-core processors, and desktops more aggressively than laptops.

Cache 

The Core i7 processors have, in modern terms, what seems like a very small increase in cache over the Core i5 processors, only a 2MB difference. When it comes to cache, this number, smaller than most MP3 files, is actually huge, marking one of the most important differences between the two series of chips.

Cache is like a bag you can drop extra items you need a lot into, allowing you to grab them quickly when you need them without having to ask RAM for them. If you have a small bag, you won’t be able to drop much in it, and when it fills up you’ll have to go store items someplace more permanent. The time needed to do that slows everything down.

Not only do Core i7 processors have a greater amount of cache than Core i5 processors, they’ve also been designed to make full use of the extra memory afforded to them, speeding up repetitive processes and lowering power use and memory demands

Power

or the most part this isn’t a huge factor when deciding whether to choose a Core i5 or i7, as all power supplies generate enough energy to power an i7 processor, and the included cooling will support the chip as long as it isn’t over-clocked. That said, a computer with a Core i5 chip will have lower power and heat than a computer with an i7 chip.

Heat and power are the limiting factors of performance for all processors, and they determine the advertised characteristics of each chip individually, a practice known as binning. Rather than producing chips that work towards a certain speed or functionality, Intel produces as many high-end chips as it can. After production is finished, the chips are measured, and then placed into models (sorted into bins, in other words) based on their ability to achieve the listed speed and market demand.

Extreme Edition

While we’re on the subject of Core i5 and Core i7, it’s worth mentioning Intel’s Core i7 Extreme lineup, also known as Broadwell-E. These massive chips extend the power of the highest-end Core i7 chips with even more cores — up to 10 in the Core i7-6950X  — better overclocking controls, and expanded support for multiple GPUs.

These chips sport almost twice the pins of a standard Core i7 chip, and require a different motherboard chipset — called X99 — than all of Intel’s other processors

Price

When it comes to price, there’s a clear difference between the two series, with some of the Core i5 chips starting from ₹13500. The Core i7 chips run a premium, starting at ₹16000- ₹35000. While it’s common to find processors on sale for a significant discount with a compatible motherboard.
