D Flip-Flop

D-FLIP-FlOP

The D (data) flip flop is a slight modification of the SR flip flop . An SR flip flop is converted to a D flip flop by inserting an Inverter between S and R and assigning the symbol D to the single input. The D input is sampled during the occurrence of a clock transition from 0 to 1. If D=1, the output of the flip flop goes to the 0 state.

Characteristic of D-Flip-flop:

                       

          From the characterstic table of the D flip flop are Q is determined by D input. Q output of the flip flop receive its value from the D input every time that the clock signal goes through a transition from 0 to 1.

    A J-K Flip Flop is the refinement of S-R flip flop. Inputs J and K behaves like input S and R to set and clear the flip flop respectively. When inputs J and K are both equal to 1, a clock transition switches the outputs of the flip-flop to their complement state.

The J input is equivalent to the S(set) input of the SR flip-flop and the K input is equivalent top the R (clear) Input. Instead of the indeterminate condition, the JK flip flop has a complement condition Q(t+1)=Q’(t) when both J and K are equal to 1

Introduction to Flip Flops

• The digital circuit considered thus far have been combinational , where the output at any given time are entirely dependent on the inputs that are present at the time .

• Almost every system has likely to have combinational circuit. Most system encountered in practice also include storage elements, which required the system be describe in terms of sequential circuit.

• The most common type of sequential circuit is synchronous type. Synchronous sequential circuit employ signals that affect the storage elements only at discrete

Instant of time .

The storage element employed in clocked sequential circuit are called flip flops

A flip flop is binary cell capable of storing 1 bit of information .

It has two output, one for the normal value and other for the complement value of the bit stored  in it.

Be A Best Parents.

The way you raise your children is the way you raise your future  generations. Since few of us have had formal training in the fine art of parenting . Most of us simply treat our children the way our parents treated us. We know of no other way to do it.

        Although being a parents is a great joy. it is also a privilege that involves tremendous responsibility. While I would do anything for my childrens. that willinginess is not enough. We need to devolop the skills of excellent parents. We cannot just hope that the way we are raising  our kids is the right way and pray that we will be lucky enougy that they become thoughful. caring and wise adults. We must take the initiativeto improve our parenting abilities by attending seminars , reading books and listening to audiocassettes by the leading thinkers in this fields. Then we must have the courage to keep trying to refine the ideas we learn in the laboratory of our ownlives in order to find the parenting strategies that best suit families.

     I know your life is busy and there is too much to do in too tittle time. But those miraculous years of your sons ans daughters "CHILDHOOD WILL NEVER CONE AGAIN". And if you do not devote the time and effort to becoming the best parent you know you can be, one day you will deeply regret the lost opportinity. 

I  realize one thing: I would give anything in the world to give that tittle boy a piggyback ride.

How to Root your Andriod Device or tablet

   

Rooting

What is rooting:

Rooting is jailbreaking for Androids, and allows users to dive deeper into a phone’s sub-system. Essentially, it’ll allow you to access the entire operating system and customize just about anything on your Android. With root access, you can also get around any restrictions that your manufacturer or carrier may have applied. You can run more apps, you can overclock or underclock your processor, and you can replace the firmware.

Three rooting programs that have garnered some attention in the past few months — Towelroot, Kingo Root, and KingRoot. 

They will root your device in the time it takes to brush your teeth. 

However, these rooting programs are only compatible with Android devices running something 

earlier than Android 5.1 Lollipop. 

For example, King Root claims it will root more than 100,000 devices, and even some running

 Android 5.0, but the majority of newer devices running Android 5.1 and higher don’t make the

 list...

• Google/Nexus
• HTC
• Huawei
• LG
• Samsung
• Sony  
• ZTE                                                                                                                                          

Why would you root?

       One of the most obvious incentives to root your Android device is to rid yourself of the bloatware that’s impossible to uninstall. You’ll be able to set up wireless tethering, even if it has been disabled by default. Additional benefits include the ability to install special apps and flash custom ROMs, each of which can add extra features and streamline your phone or tablet’s performance. A lot of people are tempted by the ability to completely customize the look of their phones. You can also manually accept or deny app permissions . 

You won’t find a lot of amazing must-have apps when you root, but there are enough to make it worthwhile. For example, some apps allow you to automatically back up all of your apps and their data, completely block advertisements, create secure tunnels to the Internet, overclock your processor, or make your device a wireless hotspot.

Why Wouldn't Root?

• Voiding your warranty: Some manufacturers or carriers will use rooting as an excuse to void your warranty. It’s worth keeping in mind that you can always unroot. If you need to send the device back for repair, simply flash the original backup ROM you made and no one will ever know that it was rooted.

• Bricking your phone: Whenever you tamper too much, you run at least a small risk of bricking your device. The obvious way to avoid it happening is to follow instructions carefully. Make sure that the guide you are following works for your device and that any custom ROM you flash is designed specifically for it. If you do your research and pay attention to feedback from others, bricking should never occur.

• Security risks: Rooting may introduce some security risks. Depending on what services or apps you use on your device, rooting could create a security vulnerability. For example, Google refuses to support the Google Wallet service for rooted devices.

 Preparation for root

Back up everything that’s important to you before you start. 

You should also always back up your current ROM before you flash a new one.

You’ll want to ensure that your device is fully charged before you begin.

Installing the Android SDK tools-

Some Android rooting methods require you to install ADB andUnlock your bootloade

Before you get started, You will also need to unlock your bootloader.

Bootloader is a program that determines which applications will run in your phone’s startup process.

Unlocking your bootloader will allow you to customize your device.

Manufacturers have responded to a demand for customization. Many of them have provided 

methods to help you unlock the bootloader on their website, though they are generally provided

for developers, and they usually require you to sign up or register an account first

Here’s Kingo’s list of compatible devices, and the following links by manufacturer are what

 KingRoot can handle:

If you’re looking to root newer phones running Android 5.1 or higher, like the Galaxy S6 or 

Galaxy S7, the above methods will not work. While they might have worked on Android 5.0, 

Android 5.1 is a completely different story, since a modified kernel needs to be flashed in order to 

achieve root. The kernel is the core of the operating system and it controls the hardware. Android

cannot run without it.You’ll also need to turn on USB debugging, as well as OEM Unlocking.

Open Settings on your device. If  you do not see Developer Options toward the bottom of 

the Settings screen on your device, follow these steps to activate them.

Steps to be followed for rooting:

   1. Go to about phone After that click on Device Information.

   2. select on Build number and tap multiple times .

   3. Go back to setting after that Devoloper option and Select USB debugging.

   4. Now your device allows you to for USB  Debugging

   5.Check to enable OEM Unlocking.

You can download the software here or the Android APK. We recommend using the Android app tool, since it’s so much easier. After you have installed the APK file, just follow the instructions below:

• Open the KingRoot app
• You will see Try to Root if your device is compatible. Tap on it.
• Be patient because it can take a while.
• If successful, you will see a large check mark with the words Root successfully below it.
