The purpose of DNS
- Web browsers interact through
internet protocol addresses. DNS
translates domain names to IP
address so browsers can load
Internet resources.
- The process of DNS resolution
involves converting a hostname
(such as www.example.com) into a
computer-friendly IP address (such
as 192.168.1.1).
- DNS recursor: The DNS recursor is a server designed to receive queries from client machines through applications such as web browsers
- Root nameserver: The root server is the first step in translating (resolving) human readable host names into IP Types of addresses. DNSsearch for a specific IP address, and it hosts the last portion of - TLD nameserver: This nameserver is the next step in the a hostname (In example.com, the TLD server is “com”)
- Authoritarive nameserver: If the authoritative name server has access to the requested record, it will return the IP address for
.com, .net and .org How domain names are organised and managed When a domain name is typed into the browser, the computer
- Second level domains typically provide the name of the organization
- Third level domains is typically used to refer to a specific server such as : support, www,… Explain the purpose of communication protocols Communication protocols allow different network devices to communicate with each other. They are used in both analog and digital communications and can be used for important processes, ranging from transferring files between devices to accessing the internet.
Server Hardware means the computer hardware provided by CentralSquare on which the Licensed Software has been installed by CentralSquare and which operates in a local area network that runs administrative software which controls access to all or part of the network and its resources and makes such resources available to computers acting as workstations on the network.
Explain the purpose of Web server software
A web server is a computer that
runs websites. It's a computer
program that distributes web
pages as they are requisitioned.
The basic objective of the web
server is to store, process and
deliver web pages to the users.
This intercommunication is done
using Hypertext Transfer
Protocol (HTTP)
There are protocols that are found in the application layers of the OSI 7 layer model. These protocols are used with the regard to hosting and managing a website.
- HTTP: It is used to deliver data on the Internet and provide a regulated method for computers
- HTTPS: It encrypts the data by exchanging keys with the customer and the website so that the encrypted data cannot be stolen
- FTP: When creating a website, the FTP protocol is used to upload the completed web pages to the webserver Relationship between technologies above with regards to designing, publishing and accessing a website.
- SMTP: This protocol is cooperated with the Mail Transfer Agent (MTA) and POP3 protocol to receive emails from users and send emails
- Apache and IIS manage every connected server and good security features. It also helps to keep the websites on the servers up and running.
- These technologies represent the level at which application programs talks with the network using programming interfaces to host and manage a website.
