Patching in windows

What is Patching or Patch Management?
Let say multiple system are installed in a organisation and all are connected to same domain controller(windows server 2012,2016,2024) and let say client system have win8 or win10 or win11.
Let say all client are connected to domain controller and are domain member.

Time to time windows do some updates in the operating system.So these updates need to be installed on the client systems.Patching or patch Management is the management of these updates on the client system.

 Any provider like Microsoft, apple or Linux when create any operating system it tooks a lot of time in behind so every months or two they can not design new operating system so basically they introduce new features in the old operating system only, rather then building new operating system with new features, so what these organization's do is create patches and these upgrades are automatically being loaded to the windows all around the world.

Obviously there are background servers managed by these company which managed these operating system of all consumers all around the world, so when ever a new patch or upgrade is released these servers automatically upgrades for those users who have enabled auto update, and for others the notification area sent.

In sort patches are new upgrades on the operating system that must be installed in user system for smooth functioning of the system.

How to be a DATA Analyst

To become a data analyst one need to be good at maths, basically numbers and visuals are two things every data analyst must know about. In my experience I believe domain knowledge and understanding the business is one of the key factor one would be needing to sort out pattens or analysis from the business data. Until and unless I don't know what my details is telling to me how I can be sure what to analyse. After all these basically a series of tool is important so that the work of analyst becomes easy, let's say tools like Excel, SQL , visualisation (tableau, powerbi), cloud computing (azure,AWS), modules in python like matplotlib, scikit learn, seaborn, pandas are some of the basic necessities that need to be fullfill. Some guidelines if I have to say is: 1) always try with clean data, then move to dirty data(mostly wrong columns values, mismatch column values, redundant data) 2) making quick visuals are always a better approach to increase confidence and skill in the path 3)...

SQL Interview Question

  SQL Interview Question: You are given two unrelated tables: Product — containing product details ProductSubcategory — containing subcategory details There are no common columns , and no foreign key or primary key relationships between them. Task: Write a SQL query to perform a join between these two tables, despite having no direct relationship. Query And Related Table: The problem with the above script is when you have exact match between the "product description" column and "subname" column then this code will work, but let say you have difference like Gadget and Gadgets then in this case the query will fail.  Feel free to post you comments over this solution, my approach would be: 1) Do the match over the letter by letter then count the total letter matched and then total letters if the percentage for this is above 80% then this record must be in the join condition. Basically perform the lookup with the help of SQL code. 2) Make abridge...

HTTP request to get data import into Database

What is HTTP request? It's a logic that can be used in order to pull data using api's created by individuals both private and public. Some API's are build in house to use it for own use and some are public API's, there are series of methods that can used in order to fetch data using these public API's. Let's see some of them: 1) GET: it is used to request some data from the frontend, usually the website URL, access token is required and in the URL itself the path is specified that someone is looking for. Let's understand with an example:- For a college website xyzuniversity.com, if I need to call the record for a student name "Alex" I will be writing the URL like GET http://university.com/student-record/alex:? And in the response I will be getting the associated record in JSON format. Here we used the GET method to call this data, like this we got multiple methods like PUT, HEAD, DELETE, PATCH,OPTIONS etc that can be used based on the need. Let...
