Let's start with Google Chrome.
I personally really like this browser. My Internet, roughly speaking, is not very fast, and this browser really surprised me with its speed. Before that, I tried Opera, Internet Explorer from Microsoft and Fire Fox (Mozilla Firefox). It is convenient to use the VKontakte website.
Another obvious advantage is that it is cross-platform; it can be used both on a stationary home computer and on mobile platforms, smartphones, and tablets.
Special Contacts Features
First of all, Google Contacts is as functional as possible. They will be an excellent tool for both managers and ordinary users. The reason is that thanks to the presence of additional features, working with huge databases is as simple and enjoyable as possible. Let's look at the most interesting functions of Google Contacts and their areas of application.
Maximum number of rooms
In total, you can add up to twenty-five thousand numbers . The number is impressive, and considering that usually no more than a hundred are stored on smartphones - especially so. This is why Google Contacts can be used, for example, to maintain a customer database.
Installing photos
Contacts with installed “avatars” are the fastest and easiest to find. Thanks to the built-in crop function, you can even take group shots. The only negative is that you cannot take an image from the Internet, you can only download it from a mobile or PC.
If a photo mounted on a contact disintegrates into pixels, try taking a larger image.
Cloud storage
Thanks to the backup function you will not lose data if your phone (tablet, laptop) breaks down. All information will automatically remain in cloud storage if you make backups in a timely manner. The application works with any OS (including iOS).
After deleting a contact, it goes to the Trash. Recovering deleted information is possible within thirty days, after which the number will be erased from memory forever.
Creating groups
To simplify your search, you can group contacts by field of activity, place of acquaintance... For example, “family”, “colleagues”, “teachers”, “friends from university”. Groups are automatically sorted alphabetically. To arrange them in the order you want, put a serial number in front of each name.
In addition, the user can simply divide contacts into “Frequently Used”, “Rarely Used” and “Spare” groups. This is the most convenient of the options. In a word, groups are created purely at your discretion.
Quick database search
By adding notes, you can easily find the number you are interested in. For example, if in the notes to a contact you indicated that this is your old friend from school, just enter “school” into the search bar, and the contact will immediately appear.

This option is especially convenient if you store more than a hundred contacts and do not always remember everyone by name. All you have to do is add notes to each number as you add it.
The only problem is that mass editing of contacts is not available. You can add the same note to all contacts when they are in the same group.
How single sign-on works
For the user, everything looks simple: he clicked “Login via Yandex”, confirmed to Yandex his desire to enter the desired site, and that’s it - you have already registered on the new site and can use it. But what's going on under the hood?
When a visitor, for example, to a website about programming, clicks “Log in via Yandex,” this site sends a request to Yandex and says: “Someone here wants to log into my site through your service, can you sort it out?”:
When Yandex receives such a request, it needs to understand what kind of visitor came to the site and whether he has a Yandex account. To do this, it shows a pop-up window where the visitor can log into his Yandex account. This is necessary so that the service understands in whose name to issue a pass for the site. If the user is already logged in to Yandex, he will be recognized immediately.
As soon as the visitor enters his username and password, Yandex recognizes him and asks if he trusts this programming site and whether Yandex can share data about his name and email with the site:
Next, Yandex gives your data to the site, it recognizes you, and you’re done:
