What is Operating System? (OS)

Hello friends, today we are going to talk about Operating system. What actually Operating System is? As you know we always keep it simple for you to understand easily, so it is very easy to understand about operating system.

An Operating System, referred to as an OS, is actually a set of programs that manage all the functions of computer. It works as a brain of computer. As our body needs brain to do various functions just like that operating system or OS work as a brain of the computer which tells the computer how to work and how to interact. Like, without brain our body isn’t capable of doing anything so without operating system we are not able to do anything on computer. It manages the hardware and software.

We can also describe an OS as a principal of the school. A principal of a school has various responsibilities like supervising students, teachers etc. If there is no principal in school everything become unorganized, similarly, an OS organized everything in a computer system.

Operating System is also known as system software. Computer requires specific instruction and these instructions are converted into a machine language so the computer can understand the requirements of the users. Operating system helps us (user) to interact with software and hardware to perform the specific function.

In computer system, we have a bunch of hardware like monitor, keyboard, CPU etc. and Operating System organizes files and let hardware know what it should do. Operating System acts as a coordinator between the Hardware and Software of a computer system. Operating System also performs some basic tasks like controlling inputs and outputs. Nowadays, operating system gives us a graphical user interface, popularly known as GUI, for higher functions. We can also say that the OS forms a platform for other system and application software.

In early days of computer, there was only one OS but time to time, when the computer progressed, the Operating System turned into Microsoft Disc Operating System, known as MS-DOS. But, also MS-DOS was not capable of doing many tasks without the software.

What is the need of an Operating System?

I hope you are already understands about the need of an Operating System in computer system in above discussion. Now, we will provide you some more knowledge about the need of an OS in just three points:
  • What to do?
  • When to do?
  • How to do?

To explain these points let’s take an example of gaming. I hope you all play games on computers, Sony PlayStation, X-Box etc. While playing the games you used game board, joysticks, remotes, monitors or disk holder – hardware. And the sound and animation effects – software.

What to do?

To perform a set of moves in the game for the game characters.

When to do?

All the things or moves in a specific character done when we pressed the required buttons in a correct sequence.

How to do?

Through proper communication with application software, and instructing it about the correct motion of the players which we see in our screen.

Why it is a System Software?

This is also a very common that why OS is system software not application. So let’s see… if you want to run any application software you required an Operating System, without OS any application software cannot run on computer. Operating System does some important tasks for you to give a best result like, taking an input from keyboard, processing the instruction and giving the output from the computer screen.

Application program is run on OS but an application program must be written in that way so it can run on any specific operating system.

 I hope you understand everything about Operating System. Still, if you have any doubts related to anything you can feel free to comment below and please share to your friends...

Difference Between 32-Bit and 64-Bit | Which is Better? | 32-Bit vs 64-Bit

Hello friends, today we are going to talk about 32-Bit and 64-Bit Processor.

Difference Between 32-Bit and 64-Bit

32-Bit processor was the primary processor, Windows 95, 98 and XP was running on 32-Bit processor. But after the creation of 64-Bit processor by IBM in 1991, technology took a noticeable turn. But 64-Bit processor came in use for common people when Microsoft launched its operating system Windows 7 and 8 with 64-Bit processor.

After that the confusion arise, what is the difference between 32-Bit Processor and 64-Bit processor. The biggest difference between 32-Bit Processor and 64-Bit processor is the number of calculation done by CPU simultaneously. It also affect the speed of the computer system.

The next big difference between 32-Bit Processor and 64-Bit processor is: RAM support. 32-Bit Processor CPU only support less than 4 GB RAM whereas 64-Bit processor can support more than 4 GB RAM.

The varies in the support of RAM also give the advantage to 64-Bit Processor in gaming. Most of the best games which have excellent graphics required more RAM which only possible in 64-Bits.

This feature is also useful for engineers, web designers etc. They use high level softwares which mostly support 64-Bit processor.

Another advantage for 64-Bit users is they can install an operating system with both 32-Bit Processor and 64-Bit processor but 32-Bit users can only installed operating system with 32-Bit processor.

In the end, 64-Bit processor quickly taking the place in every home, because of its extra advantages. Now after this, decision is yours because you are the one who have to use the computer. Please choose the right processor as per your requirements.

iOS 11 || Features of iOS 11

iOS 11 is the latest operating system launched by Apple Inc. Its Beta version was introduced t the company’s Worldwide Developers Conference. That conference took place on June 5, 2017. Its stable version was release on September 19, 2017 for consumers in most of the countries. Here we are going to talk about some of the eye-catching features of Apple iOS 11.

New Control Center

The totally new Control Center is the biggest change in iOS 11. Now you have to swipe up in your iOS and you will see the new look. Instead of small boxes at the bottom of the screen, you will see the full page Control Center. The new Control Center covers the whole full-page which helps you to choose whatever you are finding instead of scrolling. Now, you don’t need to scroll for more features because the new Control Center will display all features at once.

Because there is no color and every icon looks similar to each other so you may find difficulty to choose whatever you want, you have to search it in the whole page. But if you are using the iOS for a long time it will be easier for you and this new Control Center will seems more effective than the earlier.

Add Your Own Function in Control Center

Other eye-catching feature in Control Center is the new function of adding your own function as your choice in Control Center. From Control Center Menu you can choose the stuff you want to add. You are not allowed to add the shortcuts of App but you can add the shortcuts of a number which you want to access easily. 

Some functions you get to add in Control Center are:
  • Apple TV Remote
  • Magnifier
  • Stopwatch
  • Alarm
  • Low Power Mode
  • Flashlight
  • Wallet
  • Screen Recording

Go Inside for Turning Off Wi-Fi and Bluetooth

The one feature most of the people are talking about the function to Turn-Off the Wi-Fi and Bluetooth. Control Center doesn’t actually turn Wi-Fi and Bluetooth off. If you actually want to turn them off you have to go deeper into iOS Controls.

When you press the Wi-Fi and Bluetooth button to turn them off in control it actually doesn’t turn them off. It actually disconnects the other mobiles which are connected to that iOS 11 based phone. But the radio waves of Wi-Fi and Bluetooth are still on, and if you want to turn them off you have to do something more:
  • Select Wi-Fi Service in Settings, and
  • Then toggle the switch to turn them off.
It will turn it off completely. If you want to use your battery life effectively then I’ll recommend you to turn Wi-Fi and Bluetooth completely off.

Sharing the Wi-Fi Password become Easier

In iOS 11, it becomes easier to share the Wi-Fi Password with security. If you want to share your Wi-Fi Password with your friends or family members or anyone else who are using iOS 11 in their Apple Products or using a MacOS higher than Sierra, then you can share your Wi-Fi Password simply. You only have to save their contact info in your device.

After saving the contact info, hold the phone which you want to get connected, near yours. Then, you’ll see the push notification asking if you had likes to share your Wi-Fi Password. If you press the ‘Share Password’ option in dialog box then the password automatically populated on the other phone and you don’t even need to type it. By this you don’t even need to tell them your password your Wi-Fi Password will secure.

Emergency SOS

When you download the iOS 11 before doing anything you want to go and set up the emergency SOS. Whenever you press the power button continuously five times in a row, this feature will get activated. When you do this, your phone can call emergency services and also get notify the contacts which you choose to be a emergency contacts whenever you are in situation and send your location. It also a type of security because when you activate this, it also disables the TouchID of your phone, so no one can access your phone’s data.

Live Photo

iOS 11 has the more better feature of Live Photo than the earlier ones. It gives the Live Photos, animated clips which are recorded. It also gives the feature to customize it.  The customize feature is just as in Instagram, but here you don’t have to post your picture in Social Media. In this, you can also add the feature of loop in which the clip repeated over and over. Also, you can bounce the video forward or backward, you can also compress the video and pictures.

Keyboard with One-hand Type Feature

iOS 11 also provides the new and more featured keyboard. One more feature which makes the iOS 11 new keyboard make it better is the feature of better one-hand Type feature. In this features, the keyboard compresses and shifted either to left or right side as your need. To made the keyboard one-hand typed, you can press and hold the emoji button on the keyboard and then slide your finger either towards left or right side, whichever you need.

QR Code Scanner

For scanning the QR code by iPhone, users had to download the poor third-party applications but now Apple gives the users its own QR Code Scanner. So, now users not need to download the third-party application and also secure their phones from downloading unaware applications.

Apple Pencil Users

Apple Pencil Users now get the more efficient iOS for using their pencil. Now they can make open a Note App in iOS 11 by just stylus automatically, even in a lock screen. This will more helpful for iPad Users.

5 Features that are Copied from Android in iPhone X | iPhone X vs Samsung Galaxy Note 8

Apple has launched its iPhone X. It is the Tenth Anniversary iPhone that's why it is called iPhone X (Tenth). Tim Cook, CEO of Apple, also introduced Apple TV 4K and Apple Watch Series 3. But the most awaiting launch was of iPhone and Apple lauched its three iPhones: iPhone 8, iPhone 8 Plus and iPhone X. iPhone X pitched as 'The Future of Smartphones'. As most of the people are saying that iPhone X is a revolutionary phone. But we think that it is far away from the title 'Revolutionary'.

Today we are going to talk about the features in iPhone X that was already available in many other Android phones from many years. We are not hating any phone. We are only provide the information for you and only give our suggestions. So please don't hate our views. And enjoy reading.

Wireless Charging

Wireless technology is very old. As we all know that wireless charging was available with numerous smartphones from many years. But Apple iPhone 8, 8 plus and iPhone X are the first phones in which Apple provides wireless charging.

Smartphones based on Android had already launched with the wireless charging. All iPhone lovers are eagerly waiting for this evolution but those who are using Android phones, are getting these functions in many phones.

In some countries, Samsung, Android based company, had start giving wireless charger for free with its Note 8 series. So that's the exact point - Apple is so late in entering the Wireless world.

OLED Display

Since beginning, Apple is using standard LED display on every phone.  Also, iPhone 8 and 8 plus are still have standard LED display. However, as we know, iPhone X is the first iPhone ever which has OLED display.

But, Samsung are using AMOLED display in its most smartphones, which came in 2009 whereas iPhone gives OLED display first time in 2017. Samsung also start using SAMOLED display in its Samsung Galaxy Note 8 series.

So again, iPhone is too late in using OLED display.

Dual OIS Camera

Apple has just launched Dual OIS camera firstly in iPhone X.  Dual OIS means Dual Optical Image Stabilization. Apple added OIS Rear Camera. Samsung Galaxy Note 8 has also Dual OIS camera with its both rear camera. Most of the people are saying that iPhone is technically beat by Samsung in new functions. Yes, it is...!

Face ID

Apple launch iPhone X with something called Face ID. Face Recognition is not a new technology in smartphone world. Most of the companies had already given the Face ID type function, like Microsoft Lumia etc.

Again, Samsung beat Apple in this also. Samsung not even giving Face ID. It is also giving Iris Scanner. And no one knows that when iPhone will give this feature. Samsung Galaxy Note 8 series have Face Recognition with Iris Scanner which are working properly.

Swipe-Based Interface

iPhone's swipe based interface is not a new function. We have already seen this type of interface in many other Android phones. Recently, Nokia N9 and Blackberry Z10 also has Swipe based interface. 

So, at the end we can also say that Samsung beat Apple in adopting new technologies. You can also go for Samsung Galaxy Note 8 series if you want new technologies in less price comparatively than iPhone 8, iPhone 8 Plus and iPhone X. But if you are iPhone Lover then you can go to buy iPhone X.

What is Linux Operating System? | Linux OS

Hello friends, today we are going to talk about the most famous free and open source operating system, which is none other than – Linux.

Linux Operating System

Linux is a computer operating system. It is free and based on open source software development. It’s most important component is Linux Kernel.  Linux Kernel was first introduced on September 17, 1991 by Linus Torvalds. It is written in Primarily C and Assembly. Linux is based on Unix-like Operating System Family. The Kernel type use in Linux is Monolithic or Linux Kernel.

Originally, it was developed for Personal Computers (PC) which is actually based on the Intel  x86 architecture. But, after that it has been ported to many platforms. Linux is being ported to many platforms than any OS. Linux is the leading operating system on servers.

Other big iron system like Mainframe computers etc, are also using Linux operating system. More than 2.3% of Desktop Computers are running on Linux in the World.

The Linux development is considered as one of the most famous and also prominent example of free and open-source software. As we know that the open-source software is a type of software which is available with its source code in market with its license.

As we know, Unix became most popular and likable operating system in 1980s. But because of its many restriction most of the people stop using it. So, most of the people think that why not they made an operating system just like Unix but without any restrictions and this made the birth of Linux.

Unlike Unix, Linux gave users the free way to anyone to share things and improve as per their requirements.

The ‘Tux’ – the Penguin is the symbol of Linux. The name of the Penguin is Tux. The idea of the penguin came from the creator of Linux, Linus Torvalds. Larry Ewing was made this logo for a competition to create a Logo. This logo didn’t win the competition but was picked as a mascot for Linux, whenever anyone see the Tux, it means that it will work with Linux.

As we talk above, the most of the code of Linux is written in primarily C. Around 71% of the source code  is written in C and rest is written in C++, Assembly Language, Fortran (Formula Translator), Phython, Perl and various other.

There are many several other operating system that use the Linux Kernel:

NOTE: If you want to know about these operating systems in details so please comment below and we’ll add them soon.

The ‘Kernel’ is just like the core of computer program in an OS. The kernel helps as a connection between the hardware and software of a computer system. Therefore, it controls everything which occurs in the computer system.

GNU General Public License (GPL), licensed most of the GNU software and also Linux Kernel.  ‘Linux’ is a trademark of Linus Torvalds.
