Here, the customers are the users and the kitchen is the system that delivers the order. Here API is the critical link i.e the waiters who deliver request to and fro \n\n>* I followed the resources in the marvel website and made a weather application using the open weather api.\n\n\n\n\n\n------------------------------------------------\n## TASK 8 : Working with Github\n\n>Things I learnt:\n >* Covered the basics of what is Github and what it's used for.\n \n >* Learnt how to use Github by performing various tasks like forking a repository, pulling requests, creating branches etc.\n \n >* Also learnt how to clone a file present in GitHub using Git bash which allowed users to excute Git commands using a text based interface.\n\n \n\n \n\n ## TASK 9: Karnaugh Maps and Deriving the logic circuit\n\n In this task we had to determine the karnaugh map and make a burglar alarm using simple logic circuits. Since i didn't know much about this topic, i watched many videos and read a few articles about it.\n>Things I learnt:\n\n>* About K Maps and that they are used to simply real world logic requirements (like boolean expressions) so that they can be implements using minimum number of logic gates.\n\n>* A sum-of-products expression (SOP) can be implemented using AND gates and a product-of-sums expressions (POS) leads to OR gates feeding AND gates.\n\n>* I learnt the method of solving 3 variable K Maps.\n\nTo create a burglar alarm using simple logic circuits, we have to define the different cases based on door lock/open and key pressed/not pressed. \nHere are the four cases:\n1. Door locked, key not pressed\n2. Door locked, key pressed\n3. Door unlocked, key not pressed\n4. Door unlocked, key pressed\nTo simplify the logic, we can use a Karnaugh map for each of the four cases. \n\n Here are the Karnaugh maps:\n\n\nTo create the burglar alarm, we can use a combination of logic gates such as AND, OR, and NOT gates. Here's one possible implementation using AND and NOT gates:\n\n\n\n\n\nThis was a totally new concept to me and hence took quite a while to figure it out.\n--------------------------------------------------\n## TASK 10 : Kaggle contest\n\n>Things I learnt:\n\n>* Applying machine learning techniques to a real-world problem.\n\n>* Learn to preprocess and analyze data, handle missing values, and engineer features to improve model performance.\n\n>* Understanding datasets. The Titanic competition dataset includes information about passengers, providing an opportunity to analyze relationships between variables.\n\n\n\n## TASK 11: Working with Pandas and Matplotlib\n\nHere I had to plot a a line graph, bar graph, and a scatter plot using pandas and matplotlib. This looked very intimidating in the beginning but I decided to try and do it by watching tutorials on YouTube and asking co-ordinators to explain its significance.\n> Things I learnt\n\n >* Working with pandas and matplotlib.\n>* Plotting Line graphs, bar graphs and scatter plots.\n\n>* How python can be used for different purposes\n\nLINE GRAPH\n\n\n\nBAR GRAPH\n\n\nSCATTER GRAPH\n\n\n--------------------------------------------------\n## TASK 12: UBUNTU\n\n>Things I learnt:\n\n>* I wasn't too familiar with ubuntu so could learn more about what it is, how it works and why it's important.\n>* Ubuntu is a popular open-source Linux distribution based on Debian.\n>* It is widely used in the clou server administration, deployment of web applications, setting up databases, and managing networking aspects of servers.\n\n I peformed the operations of:\n\n* File System Navigation and Manipulation\n* Batch Folder Creation\n* File Concatenation and Display\n \n \n\n \n\n \n\n ------------------------------------------------------\nTHANK YOU\n--------------------------------------------------------------------"
