Servers are basically computers that are connected to the internet 24/7 for as long as possible. With possibly a few days or hours down time, when they need to be maintained. After discovering this we'll take a look at how our server's receive data by a packet system; also we'll review how these packets are transported over the network using ISP's. Finally we'll understand how domain name communication works and why we need domain name registration.

![Deprecated features of PHP7
[DEPRICTAED] Style constructors
PHP 4 style constructors (methods that have the same name as the class they are defined in) are deprecated. PHP 7 will return an E_DEPRECATED please only use the construct() method.
[DEPRICATED] Static calls to non-static methods
Static calls to methods that are not declared static are deprecated, and may be removed in the future.
[DEPRICATED] Password hash
The salt option for the password_hash() function has been deprecated to prevent developers from generating their own (usually insecure) salts. The function itself generates a cryptographically secure salt when no salt is provided by the developer - therefore custom salt generation should not be needed.
[DEPRICATED] Capture session meta data
The capture_session_meta SSL context option has been deprecated. SSL metadata is now available through thestream_get_meta_data() function. Deprecated features of PHP7](https://i.ytimg.com/vi/sioobwq0TAk/mqdefault.jpg)
