Synchronization - what is it and why is it necessary?

Many of us in daily life are confronted with a term such as “sync”. What is this, and why do I need it now and will be considered. Looking ahead, it can be noted that almost all the people know about this term is that not justifying it from a scientific point of view and does not delve into the issue. For better understanding, refer to computer and mobile technology.

Timing: what is this?

Let's start with a brief scientific justification. If we consider modern computers or mobile devices, the sync can be understood as a set of algorithms to store some information objects in the same state on different devices and in different periods of time, even if changes in one source.

If at least one of them down to change, it affects all other related data. On the other hand, sync can be called to display or use the same data on different devices at the moment of communication between them.

If you look at the area of application of such means, IT is possible to highlight some main aspects:

• Backup;
• Sync your accounts when you connect to the Internet;
• Sync your devices to each other;
• Multiplayer games and applications.

Basic types of synchronization

However, not only in computer systems it is possible to meet the term “sync”. What is this in production? Yes, the same, for example, when technological process involves several machine tools, which must perform a predetermined sequence of operations in a strictly defined points in time. But back to computers and mobile devices.

In General, in the implementation of all these processes there are two main type of the used synchronization algorithms: one - and two-sided.

The First type involves checking the data on two devices, one of which is the main and the second – a subordinate (for example, sync Google services with your smartphone, where server is the priority device, and the phone on which the application is installed, performs the role of a slave). In this case, the change of parameters of the same account, or backup to be created while maintaining them on the server allows you to use the data on all devices with the same application (for example, when you replace the smartphone for a different model and sign-in under the old username).

For two way synchronization is used several criteria that determine the priority device, however, the user can decide which of them will be change of information. Accordingly, the data is changed on another device. For smartphones or tablets that can be synchronized with a PC, and it does not matter where the changes are made.

Data Synchronization on mobile devices

On mobile devices synchronization is presented in several variations. First, it is connected with accounts (accounts) that you use to sign in to some apps or online services.

The simplest example is the sync account on Android devices when you sign in to Google Play. Mind you, it occurs automatically upon connection.

Second, if you have enabled the backup of data when a copy is saved in “cloud” repository on a remote server, applications, contacts and any other settings can be restored using the registered account on another mobile device.

Sync across devices

The synchronization Phenomenon can be found when you connect your smartphone to computer via USB port, via Bluetooth or Wi-Fi.

To modify objects stored in the internal and external media, special apps, no need to install. For operations with files and folders like “Explorer” by Windows or any other file Manager.

If you want to control settings or to provide access to the contact list, you will need some synchronization software (Samsung Kies, Sony PC Companion, MyPhoneExplorer, Nokia PC Suite, iTunes, and others).

Backup

Now take another look at the term “sync”. Is that from the point of view of backup? In fact, it also refers to the process of concurrent data changes and then save. But there may be two options. For example, the computer backup can be stored in specially allocated disk partition, but can use and ‘cloud’ repository.

In the first, as in the second case, synchronization occurs simultaneously, but to use the “cloud” the main condition is the availability of uninterrupted Internet connection, and saving a backup on the hard drive adds additional disk space. However, what to choose, everyone decides for himself.

In any case, take a backup and the system, and with the help of special programs. However, to obtain a simultaneous change of the data will need to choose appropriate criteria (e.g., the creation of dynamic sections to increase the volume when more space is needed). In this regard, “cloud” the technology look more attractive, however, and for these stores quite often limits the use of disk space without payment.

Why set up sync in multiplayer games and apps

Finally, another aspect. It is no secret that modern computer games allow you to use a command mode of passage. To recall the first championship in Counter Strike or Quake.

Here synchronization occurs between multiple terminals, which are the players of the opposing teams. In addition, it is possible to trace not only the synchronization actions in the game, but also the connection between players. Thanks to the advent of specialized software like TeamViewer the players were able to organize their actions through orders or coordination of movement.

And here already we are not talking about, say, creating and demonstrating presentations when you need remote access, or banking operations.

Conclusion

It Remains to add that this is not all the situations in which we can find the manifestation of the synchronization processes. Here was considered only the main aspects relating to computer technology, but the notion of this process much wider. And anyway, even in the organization of social life or sports, these technologies are used every day, only most of us are simply not paying attention, though, and knows about the phenomenon.
