How to recover data from broken or corrupted phone.

Data Recovery from Phone

It is possible to restore deleted data from mobile phones.

With the developing technology, we have started to carry all the data on our mobile phones with us. Carrying our data with us brings certain advantages but increases the risk of losing. Data recovery against the risk of data loss is of great importance. Sometimes we accidentally erased it. Sometimes we have data recovery programs for the data we regret after deleting. You can recover your data through free programs as well as paid programs. There are many data recovery programs on the Internet. If free programs do not work, you can get other programs by paying the license fee. Paid or free of charge for these programs on your phone or computer may help to recover data.

Remember to back up your short reminder data.

Bus Based Multiprocessor

bus based diagram

Bus Based Multiprocessor

Bus based multiprocessor consists of some number of CPUs all connected to a common bus, along with a memory module.
A simple configuration is to have a high speed backplane or motherboard into which CPU or memory cards can be inserted. A typical bus has 32 or 64 address lines, 32 or 64 data lines, and perhaps 32 or more control lines, all of which operate in parallel.

The problem with this scheme is that with as few as 4 or 5 CPUs , the bus will usually be overloaded and performance will drop drastically. The solution is to add the high speed cache memory between the CPUs and the bus as shown in the fig. The cache holds the most recently accessed words. All memory requests goes though the cache. If the word requested is in the cache, the cache itself responds to the CPU and no bus request is made. If the cache is large enough, the probability of success, called the hit rate, will be high and the amount of bus traffic per CPU will drop dramatically, allowing many more CPUs in the system.

However the introduction of cache also bring the serious problem with it suppose that two CPUs A and B each read the same word into their respective caches. Then A overwrites the word. When B next reads that word, it gets the old value from its cache, not the value A just wrote. The memory is now incoherent and the system is difficult to program.
One of the solution for it is to implement write-through cache and snoopy cache. In write through cache, cache memories are designed so that whenever a word is written to the cache, it is written through to memory as well. In addition, all caches constantly monitor the bus. Whenever a cache sees a write occurring to a memory address present in its cache, it either removes that entry from its cache or updates the cache entry with the new value. Such a cache is called snoopy cache. because it is always snooping on the bus.

Things to Consider When Charging Your Mobile Phones

Things to Consider When Charging Your Mobile Phones

The charge of our Smart Mobile Phones is a problem in itself. Although new methods are found every day, they are still not completely solved. We still haven't survived to charge our phone with every charger we found.

A few researches give a few tips on how to charge your mobile phone.

Let's look at these clues together.

  • After the smartphones are charged, the phone prevents electricity from going into the battery and protects the battery. However, this stresses the battery and is not healthy for battery life. Therefore, it is useful to unplug your phone after it has been charged.
  • It is said that charging your mobile phone for a short time during the day is more useful than charging it for a long time. In this way, we prevent your battery from sleeping for a long time. The battery is said to be healthier. On the other hand, when the phone charge drops below 10% and 20%, it is better to charge it.
  • It is vital to prevent your mobile phone from overheating. Almost all of us deal with our phone while the phone is overcharging. This causes the phone to warm up more. Especially this summer. Overheating of our mobile phone; the battery swells, the screen yellow, the phone can cause small parts to burn. When our phone overheats, it will be beneficial for both the battery and the health of our mobile phone to remove it from the charger and help it cool down.

WhatsApp 8 Hidden Features

WhatsApp 8 Hidden Features

We use WhatsApp almost every day. We have a few tips for using WhatsApp, which is one of the indispensable features of our mobile phones.


Are there people you talk to often? Did you know that you can add a shortcut to your device's home screen to open the chat screen
Just open the chat, press the menu button, then tap "Add chat shortcut".


Are there a lot of photos from chat groups?
To prevent images from automatically downloading to your device, go to Settings> Data usage.

Under Automatic media download, deactivate when using Mobile data, connected to Wi-Fi, and Roaming.


Are you worried about forgetting something? You can use Seebye Scheduler ROOT on Android and download Message Scheduler for WhatsApp on iOS. You will need an Android with root or an iPhone with jailbreak.


Blind Carbon Copy (BCC) is a frequently used function that prevents recipients from being aware of each other in emails.

You can activate a similar function in WhatsApp under Options> New post and select the contacts to whom you want to send your message. You'll be able to see who received your messages and send a private reply to everyone.


Your cell phone is using my other people except you.

There is a way to lock WhatsApp and keep prying eyes away. For this job, you need to take advantage of AppLock on Android and iApp Lock on iOS. The Android version of the app does not require root, while the iOS version requires a jailbreak device.


Are you a member of a group of family members or colleagues? There is no doubt that these groups work from time to time, but you probably get warnings about things that you probably won't be interested in most of the time. The problem is that if you leave the group, you should avoid breaking other members. But why would you always want to be warned about the "cute" things your cousin's new baby does?

To save yourself, open the chat you want to mute, then tap Options> Mute. Here you will find options such as silencing the conversation for eight hours, a week or a year. You can also turn off alerts from the group.


If you need to call an important phone number or email address, you can use WhatsApp's built-in calling function. Go to Options> Search and enter the phrase you're looking for.


Wouldn't it be more effective to keep the important messages ticked when they arrive, rather than hopelessly navigating the old messages? To do so, tap and hold the message you want to keep and tap the star icon that appears at the top of the screen. Messages that you have starred can be found in Options> Starred messages.

Why Android Studio

Android Programming beginners often ask questions at the beginning with which program to start programming. We would like to help you choose a program.

There are 3 major programs for Android / Mobile Programming. These; Eclipse, Netbeans and Android Studio. Those who had already started Android Programming used Eclipse and Netbeans, mostly Eclipse. However, Google has developed its own Android Programming program with the support of alternative programs. Previously, Eclipse could also be done by downloading the Android SDK plug-in. Those who still want to write Eclipse de Android Program can still download this SDK from the Internet but not from other sites over the Internet. Although this is a choice for those who are accustomed to Eclipse, it will be better for those who are new to Android Programming to start writing code with Android Studio. Android Studio, powered by Google, will be a solid infrastructure for future technologies and will allow you to produce easier programs with a convenient interface.

That is why we will choose Android Studio.
