(DOMAIN NAME SYSTEM) What is DNS SERVER ?


    (DOMAIN NAME SYSTEM) What is DNS SERVER  ?

    What is a DNS and how does it work?

    Each computer on the Internet has a unique number, which is called an Internet protocol address. When we visit a website, we connect to the IP address of the website's server and through this connection; we receive information from the site server.

    DNS - Domain Name System

    Because domain names are alphabetic, they're easier to remember. The Internet, however, is really based on IP addresses.


    For example, the domain name

    www. example.com might translate to 198.105.232.4.


    How many types of DNS queries are there?

    There are three types of queries defined for DNS: it always returns A recursive query. It does not require DNS servers to support recursive queries. An Iterative (or non-recursive) query - where the complete answer MAY be returned, or a referral provided to another DNS.


    To connect with a Website, however, we need to know the IP address of the specific server. To be more precise, our computer needs to know the IP address of the specified server.


    Here is the point at which the DNS comes like a machine God to solve the problem!


    DNS SERVER (DOMAIN NAME SYSTEM) is the initials of the Domain Name Server (i.e. Internet name server) and represents a collection of servers (i.e. computers) that work just like phone directories.


    They contain a huge state of Internet names, accompanied by the IP address of each name.


    When, for example, we type "www. xyz.com" in our web browser, we first connect to the DNS of the provider through which we have access to the Internet (Internet Service Provider) and request to be informed of the IP address that corresponds to the Online name "xyz.com".


    If all goes well, the DNS server responds e.g. 49.93.56.167, our browser communicates with the server of the XYZ site and thus the communication is made.


    If we wanted to call an old friend, we would have to get the phone book (DNS) and find his name (xyz.com) to find out his number (49.93.56.167). By calling his number, we connect to his home (server) and communicate with him.


    It updates a phone book annuallyScience Articles, while the DNS server is usually updated every 24 to 72 hours. Therefore, the new names of the Internet are made available to Internet surfers usually after 72 hours.

    Natural Alternative To Hormone Replacement Thereapy (HRT)

    M ost women experience the onset of the menopause at an average age of about 50, but it can start anytime from the early forties to the late fifties. Symptoms can vary: some women sail through but others suffer the miseries of hot flushes, night sweats, irritability, depression, lack of energy and loss of libido. Orthodox medical practitioners invariably prescribe hormone replacement therapy (HRT) and often anti-depressants and tranquillisers, which can become addictive.  However, there is a natural alternative. HRT is prescribed to counter balance the reduced production by your body of oestrogen which can lead to increased risk of osteoporosis and weakened bones leading to fractures.  However, two large clinical trials have shown that HRT does not, in fact, significantly reduce the incidence of bone fractures, and there is an increased risk of heart disease, gallstones, and breast and endometrial cancer. Rather than a shortage of hormones, it is said that most menopausal symp...
