Guide To Tackling Network Programming Assignments On Linux

Network applications following the client-server model play a significant role in facilitating communication between various devices in the computer networking field of a company. Network programming refers to the coding taking place behind the scenes of this programming.

Mastering network programming assignments is essential for those aspiring to be experts in computer networking. Network programming can be challenging for students due to its complexity and, in some cases, lack of concept clarity. Thanks to resources on the Internet like CodingZap, students can learn, explore, and receive tutoring from expert programmers to learn Linux and improve their academics. 

In this article, we'll dive into the specifications of networking programming, some valuable tips for handling network programming tasks on Linux, and examples of network programming assignments.

What Is Network Programming?

Network programming involves writing software to communicate over platforms like the Internet or a Local Area Network (LAN). This can include sending and receiving data, creating socket connections, and working with network protocols like Transmission Control Protocol or Internet Protocol (TCP or IP). 

An individual can use several programming languages, including PHP or Java, to write a specific piece of code in network programming. Web servers chat clients, and file transfer programs can be implemented into systems to help with these programs. 

Some real-world examples of how network programming is used include:

• Text Communication Applications: Text communication apps like WhatsApp and Instagram utilize network programming to develop TCPs that will take care of the messages sent by either side. They do not accept message transfers where a discrepancy has been noticed.
• Simple Email Transfer: Simple mailing websites like Yahoo and Gmail use network programming to enable the server required for Simple Mail Transfer Protocol (SMTP). When the server is ready, the required mail can be sent.
• Online Meeting Applications: Several conferencing applications like Google Meet and Zoom use network programming to develop a particular User Datagram Protocol (UDP). The system looks for data reception times and does not tolerate delays.

Understanding how to use network programming is valuable for those who plan a career where they will frequently be online.

Why Should I Use Linux For Network Programming?

Before moving ahead, we should understand why Linux has become one of the leading platforms for solving network programming assignments. There are many reasons behind Linux’s rapidly increasing use, including:

• Linux is a widely used Operating System (OS), along with Windows & macOS.
• Linux is an open-source and easy-to-access OS.
• Linux is known for its network capabilities and integrated OS components, including FTP, TCP, UDP, and services like VPN and DNS.
• Linux network administration is pretty easy and straightforward.
• Linux can support cloud computing techniques without installing additional applications. Admins can perform an array of specific tasks by simply running a few commands like “ipconfig,” “ip,” and “ping”.

Using other OSes from Linux can introduce drawbacks in network programming assignment solutions:

• Other OSes have limited resources available to work with network components. Lacking toolsets and libraries between multiple OSes can backfire for those who work on different Application Programming Interfaces (APIs).
• Using other OSes can create interoperability challenges while connecting to other networks, and many network programming experts neglect OSes besides Linux due to their compatibility issues. Linux fits properly into work scenarios that would be considered challenging in another OS. 
• Network programming is done in terminals, not Integrated Development Environments (IDEs). While other OSes can perform any operation in a separate IDE, their terminals are not efficient enough to solve all problems in one place.

Tips To Tackle Network Programming Assignments on Linux

Let’s discuss the fundamentals of network security which Linux can help solve both quickly and successfully, as these steps are valuable for everyone:

Gain Basic Knowledge Of the Concept

Look at the assignment provided to you carefully to identify the concept or subject that is used for drafting the assignment. You need to understand that field of study, so if these concepts are not in your grip, spend some time learning and refining your knowledge of the concepts. This can take between one and two days of devoted time, which will be beneficial in helping you properly take care of the assignment.

Select The Programming Language

Choose the required programming language from options like Python, Java, C#, C++, and Ruby, which deal with computer networking, that best suits your needs and can solve the questions in the assignment. Different programming languages can be used for various purposes. Python can be used for prototyping network applications, and Java is used for large-scale application development. C++ is known for its abilities in socket programming, and Rust can be used for system-level network programming.

The above-listed programming languages are going to serve you best and have sufficient network libraries and socket support, so try to avoid selecting a random programming language other than these ones.

Select The Framework According To the Assignment

All computer network programming languages have some inbuilt functions that operate as frameworks, like Socket inbuilt modules for the Python programming language.

Some external frameworks present the ability to work along with other programming languages, including Twisted, Flask, Node.js, Express, and many others. Select and use a framework based on the language and questions within the assignment.

Carefully Use Commands

Commands are a valuable aspect of solving an assignment, as they must look at the questions practically. Most of the time, computer programming assignments can be solved using a few commands in the Linux terminal. Being familiar with Linux commands and their usage is crucial in making sure you can take care of any questions or network security issues.

Pay Attention To Security

When it comes to developing a particular piece of code in computer programming, the real challenge is to provide a system-specific layer of data and network security. For instance, use software and hardware firewalls, integrate “iptables” in Linux, and implement anti-virus software like Clam AV and Intrusion Detection and Prevention Systems (IDS/IPS) to protect against network security threats and potential network security issues.

Choosing not to prioritize security can result in cloud security breaches and attacks on network security, which could have otherwise been avoided. Any unauthorized element should not enter the system, and a defense-in-depth security strategy that prioritizes the fundamentals of network security should be implemented to ensure this. This will be the final task of a beginning computer programming student.

What Are Some Examples of Network Programming Assignments?

Let’s examine some examples of network programming assignments you may receive:

Chat Application Assignment

In these cases, several clients can connect with a central server and have real-time text-based conversations through development. You can also add features like a chat room in the assignment to increase its acceptance, and a server will be responsible for maintaining the list of active chat rooms and connecting clients.

Clients will have the agency to choose what chat rooms they present, and they can send messages that will be transferred to every participant within the room. The user authentication, message broadcasting, and disconnection of any client will be taken care of by the server.

File Transfer Application Assignment

The main target of this assignment is to develop a server where many clients can upload, download, and browse personal files, as well as share other people’s files.

The server will maintain a file repository, wait for incoming connection messages from the server, be efficient enough to maintain file storage and handle any kind of error while uploading and downloading files. Clients can only perform uploads by sending files to the server, and they can only take files by searching for another client’s name.

Multi-Player Game Assignment

A central server is inevitable and essential to assignments where a student has the chance to develop their own multiplayer gaming server. The client performs more tasks in this assignment than the server, as the client will play the game.

The client first needs to connect to the server prior to joining the game, and then they can perform real-life actions like communicating with another player through chat or voice messages. The server needs to synchronize the game improvements and their database scores. Clients also need to keep in mind the aesthetics and appearance of a project since an attractive game typically performs better in various ways.

Email Client & Server Assignment

 Universities prefer when students are interested in developing email client and server assignments, as the solution involves using computer networking architecture, where several email clients are connected to a central server. The clients are able to compose emails and send them to recipients. As a client, you can access the inbox, while a server only looks at the user account credentials and stores emails in the inbox.

File Backup System Assignment

In this kind of network programming problem, the file backing system can also be developed with the client-server architecture. You need the presence of the central server, but it can be configured to appear as a personal server for an individual.

The server will make a user enter the system by checking its authentication. Then, a client can upload any data to a specific path or request a list of uploaded files to download to the local device from the server. Afterward, the server must provide proper data and network security to all paths the user goes through.
