What's going to happen if program reaches maximum limit of stack ?

If the maximum stack size has been reached, we have a stack overflow and the program receives a Segmentation Fault. While the mapped stack area expands to meet demand, it does not shrink back when the stack gets smaller.

What's going to happen if program requests a big (more then 128KB) memory allocation on heap ?

The heap is enlarged via the brk() system call (implementation) to make room for the requested block.

What's the difference between Text and Data memory segments ?

The difference between data and text memory segment is: -Data segment is contain static variables which can be modified. -Text segment is read-only and stores all code.

The articals were complicated to understanding. But I figured it out :)

The last task was really difficult for me. The command in description didn’t work for my MAC, so I had to install my virtual machine with linux. And then it worked! I’ve spent a few days to understand where is a mistake. I’m afraid, I still don’t understand why is that command don’t work on my MAC :(

Name at least three possible negative consequences of not using https:

Someone can eavesdrop your messages, someone can intercept and manipulate the message, you can’t identify who visits your website

Explain the main idea behind public key cryptography in few sentences:

Any person can encrypt a message using the receiver's public key, but that encrypted message can only be decrypted with the receiver's private key.

You are creating an application for pet clinic. You need to implement the following functionality:

POST request to add new pet. Data is sending in request body. Status code: 200 OK

GET request to search pet. Data is sending in request query params. Status code: 200 OK

PUT request to change name of an existing pet. Data is sending in request body. Status code: 200 OK

PUT request to add new info about pet's health. Data is sending in request body. Status code: 201 Created

POST request to assign a pet to a particular doctor in the clinic. Data is sending in request body. Status code: 200 OK

POST request to register an appointment for a pet. Data is sending in request body. Status code: 201 Created
