LAN chat and file sharing projects

LAN Chat apps are one of the easiest ways to chat with your friends over a LAN. No Internet connection required. The only thing required is the server IP address, and you will be able to connect to other members over the LAN. It can help you talk to friends even if neither of you have an Internet connection. Because it is LAN-based. A LAN, or local area network, connects different clients to each other as well as to the master server. Therefore, we use the same concept here, where two clients or clients and servers connect to each other and communicate with each other by providing IP addresses that can communicate with each other. On the other hand, file sharing applications are implemented where users can upload files or download files. We provide users who want to download a particular file with a path to a directory to store the file.

Online reservation system project

Online reservation system target

With this online reservation system, a practical approach is being developed to understand how the online reservation system works. The online reservation system will include all required fields required during the online reservation system. The online booking system will be easy to use and can be used by anyone. The basic idea of the project is to keep data in a central database that can be accessed by any authorized person to obtain information and save time and burden faced by their customers.

The existing system

Even if an online booking system is available, passengers must use pen and paper to fill in all the necessary details, which requires manual operation. Its main counter is not open for business due to late arrival or for some reason, in which case passengers have to wait, and in some cases they have to wait in line for the opportunity to come. After wasting a lot of time, customers are able to get their answers, and sometimes they don’t get a positive response.

Suggestion system for online reservation system

With this online reservation system, customers don’t have to wait in line, they just click to get the answer. Through the system, there will be an online form that allows passengers to fill in their details as well as their journey details. To book a seat, users will first have to search for a train on request and will have to provide a train number once the correct train is available. When the Next button is pressed, it displays its status, whether it is active or in process. Online cancellation forms will also be available, and to cancel their booking they will have to provide their PNR number again to perform the next task.

Web architect services

Web architecture services software is responsible for cloning any simple Web site that is static in nature. Sometimes, you need to get some special look and feel for a new site, and you can’t get free templates for such sites. With this simple application, you will be able to take their page and its entire background code and edit it as you choose to present it to the user. Not only will the application save you time and development effort, it will also save you additional investment in the design part. The system will also be able to display data consumption in megabytes when using the Internet

Web-based manufacturing process project

Stand-alone custom packages are difficult for any organization to use, especially for any manufacturing industry. Their industry positions may vary depending on their unit work, so working with the same type of software and different modules is not conducive to the concept of an organization that is meant to achieve common goals. But with a Web-based manufacturing process system, it provides a platform for different departments to access the same system from different locations. The Web-based manufacturing process not only saves installation time, but is also easy to use and easy to handle for maintenance.

The different modules built into it will help with the various parts needed by a particular organization. Even the admin panel has the power to set up the working modules according to its requirements by selecting the appropriate options. The number of departments and the access that staff members have to their departments can be created by the administrator and the type of work that such departments can perform. Employee information can be easily obtained by selecting departments or listing employees. By providing scratches and design, Scheduler has been integrated to start or assign new tasks to specific departments, eliminating the need to move from one location to another.

Album Manager project

Using built-in templates to organize your personal images and photos is another advantage for your creativity. Through this album creator, you will be able to view images in different styles and patterns. You will be able to list all images in grid view or matrix style. Before creating an album, you must select the type of template and provide a look and feel for the album, and all templates are provided in this single package. The tile concept has been used to improve the design portion of this Java project.

To load images into a specific album that you create, you can select one or all of them. Once the upload process is complete, it will provide the number of images, the specific size of the image, and the default name. Even from all of these features, you can select any particular album to convert all the images into HTML files so that you can use it for your personal web site just by including the name of the HTML page. The viewing part has been divided into the upper part and the lower part. A list of images is displayed at the top and a detailed view of any image is displayed at the bottom.

Global Communication Network

The Global Communications Network is a platform that enables the use of text-based dialogue media among staff. This type of communication media is preferred by technical members in their ongoing development efforts. The software provides a powerful tool for industries whose primary purpose is to exchange ideas and draw conclusions based on them.

Because the medium is text-based In English, it provides a platform for global communication with anyone in any country. With web-based functionality, it can be accessed from any remote location with public broadcast enabled. People in the technology sector are always busy with deadlines and have limited time to resolve difficulties and need to discuss with partners far away from their location to privatize communications infrastructure. It can also share their emotions by using discussion templates and patterns and their digital signatures, titles and images. Multi-person communication and composition tools have been introduced, through which two or more people can establish communication on the same topic. Because the processing and processing system will be handled by servlets, the user must select the appropriate texture and format to begin communication. Its easy installation process and low infrastructure will be highly acceptable to today’s organizations.

Library System Project

The main objectives of the Library System project are to maintain a record of the books and various documents available inside the library and to maintain a database of students who will use its library’s campus services. In addition to students, other types of users will use this system to perform processing tasks and other administrative tasks. When accessing the system, students will be provided with two options: login and registration. For first-time users (students), they must register using the system and the librarian will verify their account.

Processing the wok will be handled by three layers: the Tomcat server layer, the application server layer (that is, JDBC ODBC), and the third layer is the database layer. Certain default Settings are enforced when using the system, such as listing the required records in ascending order and by category. The main purpose of enforcement is to make it easy to access all information. A list of books will be provided along with their front images and search and browse options. In order to show the exact location of books, a virtual map system has been implemented so that any book can be easily found.

Link handler system project

Link handler systems are applications that integrate with Web-based applications. The main function of the application is to identify external and internal links available in the application and notify you to take the right action. As long as the application recognizes such a link item, it will automatically redirect to that section after final confirmation, which can be an internal or external link. Another important point is that you can check out coded sections via external links, and its unique phishing system will identify sites that are trying to steal your information or make you stupid. This application provides extended features such as chat options, an internal Web browser for handling external links and displaying pages without closing the next TAB.

With this link handler system, you don’t have to copy and paste any links that come with surfing. It identifies the link and the type of item associated with the link. To make the process easier, its automatic configuration system will handle the registry portion of your operating system to edit the registry as required, so there should be any problems when communicating. In addition, it will diagnose network problems and connection status while using the Internet.

Encryption System Project

The encryption system is responsible for encrypting user data and providing a secure mechanism for storing it in a virtual drive. This virtual drive will be created by the system for the first time for a specific user when using the system. The system will provide limited storage areas in which data can be stored. It is a cloud storage medium, so to speak, and data can be accessed from anywhere. The system also enables you to synchronize your desktop or laptop while using this encryption system.

In order to enforce security, each user should have a valid login ID and password and verify the user’s account against its valid E-mail ID. After accessing this encryption system, users can simply drag and drop their documents from their system to the virtual system. The hard drive will take some time to encrypt the document, and the process of encryption and decryption will depend on the size and type of the document. A user-friendly interface is provided so that users can easily access all provided functions. It uses powerful bit encryption and its virtual hard drive, and can be easily loaded and unloaded anywhere the user chooses.

Plan and schedule projects

The name itself is the “schedule and schedule” project, which clears up the types of functionality this Web-based Java application will perform. With this system, you can plan your future work and schedule it for execution at the expected time without any hassle. The planning and scheduling project system will enable you to track work progress and take appropriate action in a timely manner if any problems arise. In order to survive in a rapidly evolving business environment, financial management should also play a vital role in a successful business, and this can only be achieved if payment methods and mechanisms are shortened.

Its invoice management component tracks payment transactions within and outside the organization and shows defaulters after the expected time. Any file handling and processing mechanisms will be handled by the scheduler, whose scheduling methods track the routing and authentication of the files to be scheduled in. If anything goes wrong while processing the request, an immediate alert message is sent to the scheduler, which initializes this work. Its graph analyzer section will be able to provide job reports and other parameters in the form of bar charts that will help its managers take action on time.

Intranet mail system

Paperless inspections can be done by using the concept of web-based online inspections, which include automated processing systems for all work previously done manually. The online examination system can operate as a two-way way with only one system. With this Web application, you can use the concept of LAN to check over the Internet or an Intranet for a specific geographic area or a specific organization.

It will be an Internet-based system that various businesses will use to manage and keep records of the work performed at delivery agencies. After you enter your ID and password, it displays an image of the product on the screen. Express services will be provided throughout the country/region and goods will be sent by appropriate vehicles according to the size and type of products. This type of Cargo Express Courier system may be more expensive than other systems, but it is also more reliable.

Automated gym Project

There are many clubs that offer all kinds of sports for members. Sports can be cricket, tennis, swimming pool, swimming, bar, table tennis etc. The main problem with the system is to maintain staff numbers so that sufficient numbers of employees are present, but the profit earned by the employees should not be small enough to exist. Another issue is maintaining all information about members so that the number of members should not exceed the number of available places in the club, as a higher number of users would increase the chances of facilities becoming unavailable. Although meetings of all members are also a major problem.

E-mail program system

The mail program system is a simulation of the existing email system. Its purpose is to send and receive E-mail (e – mail). The project was developed using JAVA with a small number of JAVA apis. In addition to JAVA and its apis, networks and sockets (such as POP3 and SMTP) are used.

Criminal face detection system

The Criminal Face Detection System project aims to pry people’s ability to recall minute facial details by building a criminal face detection system. Criminals can be identified at the scene of a crime through fingerprints, DNA matches or eyewitness testimony. Of these methods, eyewitness statements are preferred because they are subject to rigorous scrutiny in court and are cost-effective. It is possible that the witness to the crime has seen the perpetrator, although in most cases the face of the perpetrator may not be fully visible.

In most crimes, criminals may wear masks that cover most of their faces, they may first bind and blind their victims, fold them up, or imprison them in a room before committing the crime. In other cases, witnesses may only notice the perpetrator at a glance and therefore may not be able to remember many facial details. In this case, it is useful to show the witness a section of the nose, ears, lips, eyes, etc. Wait, let’s see which one triggers memory.

The criminal face detection system will be based on existing criminal databases. High-resolution images from criminal databases will be sliced into different sections and flashed in front of witnesses. Witnesses may recall specific features and seeing the same high-resolution images will help identify the perpetrator. The images from each slice will be associated with a crime profile and can therefore provide important clues in difficult crime investigations. The system will also allow possible faces to be generated for a criminal using slice images available in the system if the witness is unable to pinpoint an offender’s face with certainty.
