Paid Anti-virus V/S Free Anti-virus

There is basically no need of antivirus at first place in either android or windows OS as they have built in protection against most common viruses, spyware etc.

The Windows OS has windows defender that act as a powerful antivirus.

BUT if you have a pirated copy of windows installed then you might need to have a antivirus as any pirated copy of Software definitely have VIRUS.

When you need a Free Antivirus

• When you have a pirated windows installed
• When you use software that are already free
• When you normally surf the internet just for FUN
• When you didn't really want a software that only available as paid version

When you need a Paid Antivirus

• When you have a original windows installed
• When you try various software that are only available as paid but you downloaded free version from just any website.
• When you have very less knowledge about internet.
• When you want after sales services that is if your PC/Laptop has got VIRUS even after installing a Paid antivirus(that is just impossible) so the company will remove the Virus without any loss of data.

What is Basically difference b/w a paid and free anti-virus??

A Paid antivirus offers all the features that has free antivirus and also more/additional features like after sales services, Anti Ransomwares Protection and many other

A paid antivirus give a extra layer of protection to your PC/Laptop But it might also make your system slow 

whereas at the same time free antivirus provide only basic features but doesn't affect performance of system 

It is so because free antivirus only has basic features that is has some modules that antivirus software has and at the same time A paid antivirus has many modules containing all functionalities that increase the size and also might affect performance of the system.

Antivirus software works on behavior detection of  files and also has virus definitions to detect known virus daily updated in virus definition.

So, at last my advice to all the readers is that always update your antivirus on regular basis so that it has latest virus definitions.

Apple iOS 13: These features will ‘change’ your iPhones and iPads soon

Apple is set to launch the next version of iOS, its operating system for iPhones and iPad. To be called iOS 13, Apple will showcase the upcoming version of the operating system at its annual developer's conference, Worldwide Developers Conference (WWDC). The WWDC 2019 will starts on June 3 and will run through June 7. Rumours and speculations have been doing rounds on the internet about the likely features that Apple is expected to introduce in iOS 13. Here are some of the key features and enhancements that are likely to come to your iPhone's and iPad's with iOS13.

• Dark Mode 

Apple may finally bring Dark Mode with iOS 13. One of the much-rumoured features, the Dark Mode is supposed to change the look of the entire UI from White to Dark Gray-ish tone or Black. The mode is claimed to be easier on users' eyes.

• A dedicated Sleep Mode

Speculations also suggest that Apple may introduce a new Sleep Mode in iOS13. Activating the mode, users won’t get any notifications until a set time in the morning

• Multiple user accounts on iPad for personalised access

Apple is also expected to introduce multiple accounts support with iOS 13. This means multiple users can use the same iPads without changing the settings and apps they are using.

• Single new app for 'Find my Friends and Find my Phone'

The 'Find my Friends' and 'Find my iPhone' services may merge into a single app with iOS 13. It is also rumoured to feature ‘find network’ to let Apple devices be tracked even when there’s no Wi-Fi or cellular network.

• Updated Maps app for easy navigation setting feature

The Maps app could also get an update in iOS 13 wherein it could get easy access options to see navigation to places visited frequently. You can see this in Google Maps mostly in the form of ‘Home’ and ‘Work’ quick locations.

• Stock keyboard finally getting swipe gesture

Several third-party Android keyboards and Google’s Gboard support swipe gestures but it’s still to debut in Apple’s stock iOS keyboard. iOS 13 could make it a reality. This may prove to be an easy and time-saving way of typing.

• New Emojis

Like every year, we will probably see new emojis coming to iPhones with iOS 13. The Unicode consortium has already finalised the emoji characters. Some include Juice Box, falafel, people holding hands, otter, waffle, sloth and more.

Android V/S iOS

Hello Guys!!!

As we all know the competition between an android and ios is very far from end. As both carries their own benefits and problems.

We know that an iOS device having 2GB RAM (hangs less) is far more responsive that an android device having 4 GB RAM (Hangs more).

So let's differentiate between these operating systems to check which is best at what level. Let's begin

1. When we installing an application in android is consumes some space and also use RAM and when we delete(Uninstalled)the application stop using any resources of a phone. This concept is called Garbage Collection and is based on JAVA. But this concept itself uses resources as well that leads to hanging problem in an android based phone.And if a device have less RAM Like 1GB it make the phone almost unusable

Whereas iOS uses ARC (Automatic Reference Counting) which is based on Objective C Language It works like if any application is not in use it automatically discarded (stop) from using the resources. This mechanism uses less resources and increases overall performance of phone.

2.  Now let's talk about the UI (User Interface).

Android has different UI's like stock android (Used in android one devices), MIUI(used in Xiaomi phones), Color OS(used in OPPO devices), EMUI (used in Honor devices) and many more. 

In android the UI uses same thread as other resources so basically all applications(Apps) including UI are running on a single thread. And also resources are also be used background also as Android gives more freedom to developers. And at one point of time it makes devices to stop unexpectedly and even crashing of some applications.

Whereas iOS uses a a separate thread for UI Which enables resources to be used by UI and Application separately and hence increases overall performance

3. In android APP management is a plus point as android developers have freedom to develop applications either professional or a non professional. So some time apps might cause memory leaks(Memory leaks can be defined as a situation where even after stopping application from running it can't able to free memory/resources)p

Whereas in iOS there is restriction for app developers that enables to permanent stopping to the problem for memory leaks and  hence it increases performance

4. The android is can be used with any phone hardware it doesn't matter. 

But in iOS it can be used with its own manufactured hardware it can't be used be with any other hardware

Look I'm not saying the this battle is over as the both OS has its advantages and disadvantages.

So, I'm just conclude it by saying that the android is NOT the WORST and iOS is NOT the BEST either.
