What Are DLL Files? Can I Download DLL Files From Internet?

ROHIT CHOUDHARY After encountering a system error popup with the mention of a missing DLL file, ever wondered what actually are DLL files? Why do we need them and what are the advantages of DLL files? They are dynamic libraries that can be called by apps during run-time. They play a major role in reducing code delicacy and performance improvement.

In Windows-based PCs, very often we come across DLL file errors that don’t allow some software to run. We get error messages telling us that some particular .DLL file is missing. To solve this issue, we search for that particular file on the web and get the software working.

But, what exactly is a DLL file? How does it work and what is its importance?

What is DLL? What does it contain?

DLL stands for Dynamic-Link Library. It’s Microsoft’s implementation of the shared libraries. It’s a type of file that has instructions that other programs can call to do certain stuff. This allows different programs to share a single file and make use of its abilities even simultaneously. Thus, a DLL file eliminates the need for multiple copies of the same file. It contains classes, functions, variables, UIs, and resources like icons, images, files etc.

On all types of operating systems, you’ll encounter two types of libraries — static libraries (.lib) and dynamic libraries (.dll). While static libraries are linked to executable files at compile time, the dynamic linked libraries aren’t linked until run-time. A dynamic library is a stand-alone file that can be individually updated without changing the EXE file itself.

How is a DLL file used? What are its advantages?

When an EXE file runs, the Windows operating system find the table of data attached to it, including the list of functions from some DLL file. After this, the loader code looks for that particular DLL file and loads it. In that DLL file, there’s another list, named export list, that connects each function of DLL file using specific addresses.

As said above, a DLL file helps to reduce the duplication of code that’s stored on the disk. This improves the performance of the programs running in foreground and background. It also helps in building large modular applications that need lots of programs or language versions for modular architecture.

Another big advantage of using DLL files is that the installation or change in DLL isn’t followed by relinking it with the programs. So, a single fix will benefit multiple programs in one go.

DLL REDUCES DUPLICATION, IMPROVES PERFORMANCE

DLL errors and fixing them

Due to a large number of DLL files and their usage frequency, DLL-related errors are very common. Whenever we encounter such error, our plan of action is to search them online and put it back in its place.

As a DLL file is often used by multiple programs, it’s stored in common locations like C:\Windows\System32 and C:\Windows\SysWOW64. However, the method of looking up for files online isn’t recommended. There are chances that the downloaded DLL files might be outdated or infected with the virus.

So, how to fix the DLL errors? Here are some methods that you can use:

• Use your Windows Resource Protection Tool or System File Checker (SFC) to fix the missing system files.
• Grab updated versions of Microsoft Visual C++ Redistributable packages.
• Microsoft .NET Framework packages
• Reinstalling the app fixes the problem most of the time.
• Request app vendor for a copy of DLL files

The Complete List who ready to get Android 7.0 Nougat Update

ROHIT CHOUDHARY : As the Android 7.0 Nougat is here, people are searching the web to know when their phone will get Nougat update. To answer your question, we have prepared a list of the popular brands, telling you about their plans to roll out the Android 7.0 Nougat update. While brands like Moto, Nexus, HTC, and LG are preparing for any early OTA update, other are likely to do the same in January-February 2017.

Every year we witness the release of a brand new version of Google’s Android operating system. While last year’s update was named Android 6.0 Marshmallow, this year we’ve got Android 7.0 Nougat.

Android Nougat is being termed as a major rollout, packing a heavy chunk of new features and improvements. Coming loaded with new features like multitasking, VR, keyboard themes, and new emojis, Android 7.0 Nougat is arriving soon to Android devices.

Keeping these great features aside, another important question is — “When will my phone get Android 7.0 Nougat update?” If we take a look at the previous records of Android device manufacturers, their performance is pretty dismal. Such situation makes it even more important to know the answer.

Talking about the final release date, it’s rumoured that Google is ready to release Android 7.0 later in August, though that seems early.

Here’s what you can expect from different smartphone manufacturers:

Android 7.0 Nougat Update Release: Google Nexus

Android Nougat release date expectation: Within few days of final Android N release

If we take a look at the history, Android 6.0 Marshmallow was rolled out to Nexus smartphones as soon as Google rolled out the final version.

The new Nexus devices are the first ones to get the Android 7.0 update and the rollout has already started. If you wish to grab the Android N, you can go ahead and check for updates in the settings of your Android Nexus phone.

Official Update: The Nexus 6, Nexus 5X, Nexus 6P, Nexus 9, and Nexus Player have started receiving updates.

Android 7.0 Nougat Update Release: Google Pixel C

Android Nougat release date expectation: Within the first month of release

Apart from Google’s Nexus lineup, company’s own Surface competitor Google Pixel C will be getting Android 7.0 Nougat update.

Official Update: Pixel C has started receiving updates.

Android 7.0 Nougat Update Release: Android One

Android Nougat release date expectation: Within few days of final Android 

Affordable Android One devices are known to receive the latest Android updates before others. This is possible as they run stock Android and Google takes care of the firmware upgrades. So, the Android 7.0 Nougat update should arrive for Android One and Nexus devices at the same time.

Official Update: Android Once devices have started receiving updates.

Android 7.0 Nougat Update Release: Moto

Android Nougat release date expectation: Early December 2016

When Motorola was owned by Google, it was one of the first devices to get the Android upgrades. Keeping our fingers crossed, under the umbrella of Lenovo, we can still expect Moto phones to be the first non-Nexus devices to get Android 7.0 Nougat update. It’ll be interesting to see how near-stock Moto Android is handled by Lenovo.

Official Update: These phones are getting Android Nougat update in 2016 Q4:

• Moto G (4th Gen)
• Moto G Plus (4th Gen)
• Moto G Play (4th Gen)
• Moto X Pure Edition (3rd Gen)
• Moto X Style
• Moto X Play
• Moto X Force
• Droid Turbo 2

Android 7.0 Nougat Update Release: HTC

Android Nougat release date expectation: December 2016

While HTC hasn’t released any specific dates, the company has confirmed that Android 7.0 Nougat will be arriving on its devices. HTC has told that its flagship HTC 10, HTC One A9, and HTC One M9 will be getting the update. This update is expected to arrive in 2016 Q4.

HTC has a good track record when it comes to pushing Android updates. It released Marshmallow update for HTC One M9 and HTC One A9 in December. The brand new HTC 10 was released in April with Android 6.0 Marshmallow out of the box.

Android 7.0 Nougat Update Release: Samsung

Android Nougat release date expectation: January 2017

Samsung is the king of Android smartphone world. But, when it comes to releasing the latest Android updates to its users, it isn’t very speedy. So, expecting a miracle with Android 7.0 won’t be much sensible.

It’s likely that Samsung Galaxy Note 7 will be the first device to get the taste of Android 7.0 Nougat, followed by Galaxy S7 and S7 Edge. After that, we can expect the update to hit the likes of Galaxy Note 5, S6, S6 Edge, and S6 Edge+.

The upcoming flagships Galaxy S8 and S8 Edge should arrive with Android 7.0 Nougat out of the box.

Android 7.0 Nougat Update Release: LG

Android Nougat release date expectation: December 2016

When Google released Android 6.0 Marshmallow update, LG released the update for its flagships within just two months of Marshmallow arriving on Google Nexus devices.

There are chances that LG G5 users will be getting the update within 2-3 months of the release of the final build. The older handsets like LG G4 should get the update in early 2017.

Android 7.0 Nougat Update Release: Sony

Android Nougat release date expectation: After February 2017

Sony is among the less speedy ones when it comes to releasing Android updates. However, Sony is known to cover a wide range of devices when it releases the update for its smartphones.

Sony Xperia Z3 is expected to be the first one to grab the Android 7.0 Nougat update, followed by the devices of Z4 and Z5 families.

Official Update: Sony has released the final list of devices getting the update — Xperia Z3+, Xperia Z4 Tablet, Xperia Z5, Xperia Z5 Compact, Xperia Z5 Premium, Xperia X, Xperia XA, Xperia XA Ultra and Xperia X Performance.

Android 7.0 Nougat Update Release: Huawei

Android Nougat release date expectation: February 2017

When we mention Huawei, generally we keep the Nexus devices out of the discussion.

Back in last November, Huawei Marshmallow treats along with Huawei Mate 8. Honor, a sub-brand of Huawei, rolled out Honor 7 Enhanced Edition in December 2016 with Android Marshmallow out of the box. Thus, looking at the history, we would expect Huawei to release a new phone with Nougat before it releases the new upgrade.

Android 7.0 Nougat Update Release: OnePlus

Android Nougat release date expectation: February 2017

OnePlus 2 didn’t receive Android 6.0 Marshmallow update until the beginning of June 2016. So, we shouldn’t expect that the company will be pushing the Nougat update for OnePlus 2 or OnePlus 3 anytime soon. Still, we would like to witness an early-2017 release with an OxygenOS flavor.

Recently, the company teased the upcoming Android Nougat update for OnePlus 3 in a tweet:

Already hard at work on the latest and greatest. #NeverSettle pic.twitter.com/pirsJS3jOD

Android 7.0 Nougat Update Release: Xiaomi

Android Nougat release date expectation: March 2017

While Xiaomi has managed to capture a huge chunk of worldwide Android market, it’s struggling to provide timely Android updates. The company was able to release Marshmallow for Mi 4, Mi 3, and Mi Note in early April.

However, if the company follows some deadlines, it should be able to push Android 7.0 Nougat update in the early months of 2017.

Need to Learn Programming Language | Best Learning Resources At Free of Cost

ROHIT CHOUDHARY : Many universities have free educational offerings in a variety of disciplines. This can make it exceedingly easy to obtain a slightly more formal education in many fields than simply reading odds and ends online. Here are some universities and their websites where you can take full advantage of their generosity.

There are always some inherent difficulties to studying without the benefit of a mentor or formal teacher. It often boils down to the fact that you don’t know what you don’t know. That is to say, you are unaware of the materials that you should learn in order to progress in your study.

Many websites to aim to help with this, but without a curriculum, it can be fairly difficult to make your way from point A to point B, and even with a curriculum to follow, you still might have to hunt down some good examples and tutorials on the different components of that curriculum. Not very many people are aware of the free courses available on the websites of different universities and other organizations. Here’s a small list of some notable ones.

• Harvard CS50
• MIT open Courseware
• Khan Academy
• Code Academy
• Open Learn
• edX (Founded by several major universities)
• All About Circuits (More electrical theory)

These are just a few, and many are not limited to computer science, you can learn anything from second languages to business and maths. While most of these will only be introductory and hardly compare to a formal degree or diploma, they are certainly enough to set you on the right track and let you build a momentum in your study.

Your debit/credit card can be hacked in less than 6 seconds

ROHIT CHOUDHARY : It may take as little as six seconds for hackers to guess your credit or debit card number, expiry date and security code, say scientists who were able to circumvent all security features meant to protect online payments from fraud.

Exposing the flaws in the VISA payment system, researchers from Newcastle University in the UK, found neither the network nor the banks were able to detect attackers making multiple, invalid attempts to get payment card data.

By automatically and systematically generating different variations of the cards security data and firing it at multiple websites, within seconds hackers are able to get a ‘hit’ and verify all the necessary security data.

Investigators believe this guessing attack method is likely to have been used in the recent Tesco cyberattack which the Newcastle team describe as “frighteningly easy if you have a laptop and an internet connection.”

“This sort of attack exploits two weaknesses that on their own are not too severe but when used together, present a serious risk to the whole payment system,” said Mohammed Ali, a PhD student at Newcastle University.

“Firstly, the current online payment system does not detect multiple invalid payment requests from different websites,” said Ali.

“This allows unlimited guesses on each card data field, using up to the allowed number of attempts – typically 10 or 20 guesses – on each website,” he said.

“Secondly, different websites ask for different variations in the card data fields to validate an online purchase. This means it’s quite easy to build up the information and piece it together like a jigsaw,” Ali said.

“The unlimited guesses, when combined with the variations in the payment data fields make it frighteningly easy for attackers to generate all the card details one field at a time,” he said.

“Each generated card field can be used in succession to generate the next field and so on,” Ali said.

“If the hits are spread across enough websites then a positive response to each question can be received within two seconds – just like any online payment,” he said.

“So even starting with no details at all other than the first six digits – which tell you the bank and card type and so are the same for every card from a single provider – a hacker can obtain the three essential pieces of information to make an online purchase within as little as six seconds,” he said.

To obtain card details, the attack uses online payment websites to guess the data and the reply to the transaction will confirm whether or not the guess was right.

Since the current online system does not detect multiple invalid payment requests on the same card from different websites, unlimited guesses can be made by distributing the guesses over many websites.

However, the team found it was only the VISA network that was vulnerable.

The research was published in the academic journal IEEE Security and Privacy.

IIT-Kanpur student gets Rs 1.5-crore offer from Microsoft

ROHIT CHOUDHARY: A student of IIT-Kanpur who hails from Delhi has received a job offer of nearly Rs 1.5 crore per annum from Microsoft. This is the highest ever salary offer to a student of IIT-K, sources at the premier institute told.

The student has been offered a position at Microsoft’s headquarters in Redmond. Sources said he will design a software, implement it and fix the bugs.

He will get $136000 (Rs 94 lakh) as base pay and $70,000 for relocation, medical and visa charges and stock ownership options. The total package, taking into account annual bonus and joining bonus, works out to nearly Rs1.5 crore. Last year, the highest base pay offered to a student at IIT-K was Rs 93 lakh.

Elated after getting the offer, the student, who requested anonymity, broke the news first to his wing mates. “This is really exciting. Software once again has turned out to be the flavour of the placements,” he said.

When we contacted student placement officer Prof Syam Nair, he said, “I am not going to comment anything on the salary packages.”
Sources said IIT-K has nearly 200 companies listed for placements this year compared to around 280 which flocked the campus last year.

This year, sources said, companies that provide technology for reservoir characterisation, drilling, production and processing to the oil and natural gas industry are missing. Both Transocean and Schlumberger, which were seen on the campus during placements till last year, are absent this year. Placements are seeing an increase in trading firms. Amsterdam-based Flow Traders walked in for the first time.

E-commerce firms like Amazon, Paytm, Ola and Uber also visited the campus. Uber, however, hasn’t recruit any student so far.
