Command line test is a BASH shell-based tool that simulates login based online testing scenarios. Initially the user will be provided with a sign-in option where pre- defined users will be allowed to login. Upon successful login this tool will display questions for the user from the existing data-base. It will also handle error conditions like time-out.

This tool will also store answers provided by users for future verification.

The art and science of hiding information by embedding messages within other, seemingly harmless messages. Bits of unused data are replaced by bits of valuable information using LSB mechanism. Sender and receiver will have individual key / secret based on which they will be able to extract the actual data from the image.

This project also gives a basic level understanding of image processing methodologies

Arbitrary-precision arithmetic, also called bignum arithmetic, multiple precision arithmetic, or sometimes infinite-precision arithmetic, indicates that calculations are performed on numbers whose digits of precision are limited only by the available memory of the host system. This contrasts with the faster fixed- precision arithmetic found in most arithmetic logic unit (ALU) hardware, which typically offers between 8 and 64 bits of precision

Mini shell is a command processor, typically run in a text window, allowing the user to type commands which cause actions. BASH can also read commands from a file, called a script. Like all Unix shells, it supports piping and variables as well. The goal of this project is to implement a mini-shell that mimics the BASH shell by using Linux Kernel System calls and IPC mechanisms like signals.

It will also handle special keyboard actions (ex: Control C), can be extended for advanced functionalities (ex: Command history) as well.

Black Boxes are typically used in any transportation system (ex: Airplanes) that are used for analysis post-crash and to understand the root cause of accidents.

Continuous monitoring and logging of events (ex: over-speeding) is critical for effective usage of black box.

The goal of this project is to implement core functionalities of a care black-box in a PIC based micro-controller supported by rich peripherals. Events will be logged in EEPROM in this project. This project can be further extended to any vehicle

Lexical Analyzer is a program which converts the stream of individual characters, normally arranged as lines into the stream of lexical tokens. Tokenization for instance of words and punctuation symbols that make up source code. The main purpose/goal of the project is to take in a C file and produce the sequence of tokens that can be used for the next stage in compilation. 

This should also take care of necessary error handling conditions that may occur during tokenization.

The Embedded Linux Mini shell Project is a command-line interface (CLI) designed to execute custom user-defined commands. This project involves porting the mini shell (msh) onto an ARM-based embedded target, providing hands-on experience in Embedded Linux. It focuses on key concepts like process creation, signal handling, synchronization, and exit status management.

Additionally, it explores text parsing and the init process, highlighting system-level interactions. By bridging theory and practical application, this project deepens understanding of embedded systems development.

This project aims to build a basic web-based chat application using TCP/IP sockets in a Linux LAN environment. A concurrent server runs on one machine, while clients from other LAN machines connect to it. Upon connection, clients authenticate using a username-password stored in a simple text-based database. After successful login, users can send messages to all chat room participants and receive messages in real time. Clients can exit the chat room with a specific command.

This project offers hands-on experience with TCP/IP socket programming, authentication, and basic database handling.
