1.Explain server technologies
Web server: Web server means the web server, which is a mainframe connected to an extended computer network. The server contains all the data for which it is authorized to manage. Each server has its own IP and can read a variety of languages such as HTML, HTM, File, ... The server has a large capacity and very high speed to be able to store and operate data stores on the internet well. Through the separate communication port of each server, the computer system is able to operate more smoothly. The server must ensure continuous operation to be able to provide data to its computer network. Application Server : The Application Server
- the Application Server, also known as the App Server - is a program that controls all application activities between users and the bottom-level applications of an enterprise organization or databases. Whether. Typical application services are typically used for basic transactional conjugate applications. To support high requirements, an application service must have redundancy within it, control for high visibility, high-level presentation, distribution of application services, and support for physical access links. database.
1.2 Management services associated with hosting:
Managed hosting is an IT provisioning model in which a service provider leases dedicated servers and associated hardware to a single customer and manages those systems on the customer's behalf. In managed hosting, customers can rent equipment such as dedicated server, storage and network hardware; operating systems; and system software. The customer usually has administrative access to the leased systems yet rarely uses it, instead opting to interact with the system through a web-based interface.
P1: The purpose and types of DNS, including explanations on how domain names are organized and managed Function of DNS each Website:The main function of DNS is to translate domain names into IP Addresses, which computers can understand. It also provides a list of mail servers which accept Emails for each domain name. Each domain name in DNS will nominate a set of name servers to be authoritative for its DNS records.
P1: The purpose and types of DNS, including explanations on how domain names are organized and managed Domain Name System – DNS: DNS has an IP search job, DNS is an essential part of the internet, it can identify various vulnerabilities when accessing.
P1: The purpose and types of DNS, including explanations on how domain names are organized and managed Managed DNS servers: The Domain Name System (DNS) is the Internet's system that converts human readable domain names into digital IP addresses and vice versa. Some of the businesses that offer Managed DNS services include:▪Dyn ▪Cloudflare ▪Amazon Route 53 ▪Cloud DNS ▪UltraDNS ▪Verisign Managed DNS ▪NeustarUltraDNS ▪Akamai
P1: The purpose and types of DNS, including explanations on how domain names are organized and managed DNS Protection: DNS protection is the concept of protecting the entire DNS service, sometimes focusing on security. DNS protection can be divided into approximately two categories:
- Protecting the DNS service itself
- (^) Protecting the entire security posture. DNS protection is not an industry standard term; Depending on the context, it may mean different things to different people
On the Internet ,there are many applications (services) and applications (services) that need corresponding communication protocols.
P2: Explain the purpose and relationships between communication protocols, server hardware, operating
systems and web server software with regards to designing, publishing and accessing a website.
There are many different services on the internet => there are many different methods of communication
P2: Explain the purpose and relationships between communication protocols, server hardware, operating
systems and web server software with regards to designing, publishing and accessing a website.
For example , Web service with https protocol proposed by Tim Berners-Lee in 1989 HTTP is also a Request - Response protocol based on Client - Server structure. Client and server communicate with each other by exchanging independent messages (as opposed to a single stream of data). Messages sent by the client, usually a web browser, are called requests, and messages sent by the server as a response, are called responses.
P2: Explain the purpose and relationships between communication protocols, server hardware, operating
systems and web server software with regards to designing, publishing and accessing a website.
HTTP Request :
- Request-Line
- Method
- (^) URL
- HTTP version
- Request-header HTTP Response:
- Status-Line.
- HTTP-version
- (^) Status-Code
- Reason-Phrase:
- Respone-header
P2: Explain the purpose and relationships between communication protocols, server hardware, operating
systems and web server software with regards to designing, publishing and accessing a website.
Method : There are 9 types of method, get and post are 2 common types used a lot The Status-Code element is a 3-character integer. The first character of the state encoding defines the response class (type) and the last two characters do not have any categorical role.
