Assignment
P1/ Identify the purpose and types of DNS, including explanations on how domain names are
organized and managed.
1/ DNS
1.1/ Definition
DNS (Domain Name System) or domain name resolution system, can be explained as a system that helps humans and computers
"communicate" with each other more easily (Because of their communication language). we are names and letters, and
computers can only understand sequences of numbers!) The system helps to translate domain names (hostnames) into strings
of numbers, so that computers can understand.


1.2/ Target of DNS
The domain name system is like a phone book. That is, instead of having to remember dozens of phone numbers with a bunch
of numbers, you just need to remember the name of the owner of the phone number. In that case, the phone number will
correspond to the IP address of the Website, and the owner's name is the domain name of that website.
For example, when you type “www.google.com” into your browser, the DNS server will get the address of the Google server as
“74.125.236.37”. You will then see the Google home page load the page on the browser you are using. That's the DNS resolution
process.

2/ DNS Server Types and Roles
2.1. Root Name Servers
Also commonly referred to as Name Server. This is the most important server in the DNS hierarchy. You can also understand
that Root Name Server is a library to guide your search.


Following the actual process, after receiving a request from the DNS Recursive Resolver, the Root Name Server will respond that
it should look in specific top-level domain name servers (TLD Name Servers).

2.2. DNS Recursor
As mentioned above, this "hardware" acts as a diligent worker, taking on the task of retrieving and returning information to the
browser to find the right information they need. In other words, DNS Recursor is responsible for communicating with other
servers to respond to the user's browser. Of course, in the process of getting information, sometimes it will also need the help of
Root DNS Server.

2.3. TLD Nameserver
When you want to access Google or Facebook, usually, your extension will be “.com” right? So, I want you to know that it is one
of the Top-level Domains. And the Server for this type of Top-level domain is called TLD Nameserver. This is the manager of the
entire information system of a common domain name extension.
In sequence, the TLD Name Server responds from the DNS Resolver, then presents it to an Authoritative DNS Server – or the
official repository of that domain's data source.

2.4. Authoritative Nameserver
When the DNS Resolver finds the Authoritative Nameserver, that's when the domain name resolution takes place.
The Authoritative Name Server, on the other hand, contains information that indicates what address the domain name is
associated with. It will provide the Recursive Resolver with the necessary IP address found in its records directory.

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.


1/ Explain of Communication Protocol 1.1/ Definition
Communication protocols are formal descriptions of digital message formats and rules. They are required to exchange messages
in or between computing systems and are required in telecommunications. Communications protocols cover authentication,
error detection and correction, and signaling. They can also describe the syntax, semantics, and synchronization of analog and
digital communications. Communications protocols are implemented in hardware and software. There are thousands of
communications protocols that are used everywhere in analog and digital communications. Computer networks cannot exist

without them.

1.2/ Purpose
Communication devices must agree on many physical aspects of the data being exchanged before successful transmission can
occur. Internal transmission rules are called protocols. There are many attributes of a transmission that a protocol can define.
Common ones include packet size, transfer rate, error correction types, handshake and synchronization techniques, address
mapping, recognition process, flow control, packet self-control, routing, address format.

2/ Explain of Server hardware


2.1/ Definition
The main server is a complex system that has the task of centrally storing data sources, processing, and accessing information coming
from other computers over the Internet. The server hardware equipment for a complete setup is like a desktop computer (also known
as a PC).

2.2/ Purpose
Servers often operate for a long time, without interruption, requiring very high availability, so hardware reliability and durability
are extremely important criteria. Because of this, when choosing a server, users should choose branded and reputable lines.
Many server hardware configurations take a long time to boot and load the operating system. Servers typically do preboot
memory checks and start remote management services.


The hard-drive controllers then start the drives sequentially, but not all at once, so as not to overload the power supply with
incremental boot, and then they start running to the system. RAID requires checks for the correct operation of the backup device.
It may take longer than a computer that takes only a few minutes to boot, but it may not need to be restarted for months or years.

3/ Explain of Operating systems
3.1/ Definition
Operating system (abbreviated: OS), in the most general sense, is software that allows users to run other applications on a

computer device, mobile device through hardware such as CPU, RAM, ROM, screen. ... Although software applications can
communicate directly with hardware, most applications are always written for an operating system, allowing them to take
advantage of common libraries without having to worry about other operating systems. specific hardware details.


3.2/ Purpose
The operating system consists of many components and features. What features are defined as part of the operating system will
vary from operating system to operating system. However, the three components that are easiest to identify are:
•

Kernel: The kernel provides basic level controls over all computer hardware devices. Key roles include: reading data from
memory and writing data to memory, processing execution instructions, defining how data is received and sent by
devices such as monitors, keyboards, mice, and monitors. defines how to interpret data received from the network.


•

User Interface: The User Interface allows interaction with the user through graphical icons and a desktop or through a
command line.

•

Application Programming Interfaces: Application Programming Interfaces allow application developers to write modular
code.

•
•

Examples of operating systems include: Android, iOS, Mac OS X, Microsoft Windows, and Linux.
Operating system features

•
•
•

An operating system is a program that acts as an interface between computer software and hardware.
It is a set of integrated specialized programs used to manage the overall resources and operation of the computer.
It is a specialized piece of software that controls and monitors the execution of all other programs located in the computer,
including application programs and other system software.

4/ Explain of Web server software

4.1/ Definition
The web server is connected and linked to an extended computer network. Web servers are installed with programs to serve
web applications, contain all the data and take control. The web server can take requests from the web browser and send
the response back to the client via HTTP or another protocol.


4.2/ Purpose
"Server" is understood to mean:
•

Hardware configuration "Physical server". There are famous server manufacturers such as Dell servers, HP servers,
IBM servers, Supermicro servers. This physical server needs to install additional software to be able to use it. The
server can have many CPUs (currently up to 200 cores), many Ram sticks (currently 6144GB Ram can be installed /
1 server), hard drives can install up to several hundred TB / 1 server .

•

or understood in terms of software - A server is a place to store / Install software programs so that many workstations

can access the centralized data storage place through the internet. Server in this sense can be "cloud vps" or even
Hosting service. But it can also be a system that includes a LOT of servers from all over the world, for example "google
servers" means hundreds of thousands of servers all over the world.


P3. Discuss the capabilities and relationships between front-end and back-end website technologies.
1/ Front-end
1.1/ Definition
The front-end part of a website is the part that interacts with the user. Everything you see when you navigate the Internet, from
fonts and colors to drop-down menus and sliders, is a combination of HTML, CSS, and JavaScript controlled by your browser.
friend.
Front-end developers are responsible for the look and feel of a website and the architecture of the user experience. To
accomplish those goals, front-end developers must master three main languages: HTML, CSS, and the JavaScript programming
language.


1.2/ Skills and tools
Good front-end developers can also pinpoint specific issues in the user experience, providing recommendations and
systematized solutions to influence that design. Crucially, they have the ability to work with other groups in the company to
understand their specific goals, needs, and opportunities, and then follow through on those directions.
This job involves a lot of responsibility, but it's well worth it. “I am a technical person, but still a visual person, and can manipulate
what we see and interact with digital platforms through markup and code spontaneously. course,” said Mikey Ilagan, a frontend
developer with eight years of experience. “Because of that, I would love to have the ability to make an impact on the user
interface, the aspects of an app or website that users interact with and see.”


2/ Back-end
2.1/ Definition
What is backend? But what makes the front-end part of a website work? Where will all the data be stored? That's the back-end’s job.
The back end of a website includes a server, an application, and a database. A back-end developer builds and maintains the technology

that, the power of those components, enables the user interface part of a website to live on.
