Finished first task.
Finally done Unix Shell part. There was some new commands, like for printing que control. I intend to use GUI instead.

Name at least three possible negative consequences of not using https. . Your massege could be edited by third part . Your messege could be seen by third part Explain the main idea behind public key cryptography in few sentences Public key helps to encript massege, but not to decript. So, anybody who has PK could send information without risk. It couldn't (in some conditions could) editet or readed without privat key.
add new pet (including name, age, breed, owner's name, medical history) search pet by name GET() change name of an existing pet SET() add new info about pet's health SET() assign a pet to a particular doctor in the clinic register an appointment for a pet. This request should include info about pet, doctor and appointment date and time.
These request verbs are:
GET: fetch an existing resource. The URL contains all the necessary information the server needs to locate and return the resource. POST: create a new resource. POST requests usually carry a payload that specifies the data for the new resource. PUT: update an existing resource. The payload may contain the updated data for the resource. DELETE: delete an existing resource. The above four verbs are the most popular, and most tools and frameworks explicitly expose these request verbs. PUT and DELETE are sometimes considered specialized versions of the POST verb, and they may be packaged as POST requests with the payload containing the exact action: create, update or delete.
There are some lesser used verbs that HTTP also supports:
HEAD: this is similar to GET, but without the message body. It's used to retrieve the server headers for a particular resource, generally to check if the resource has changed, via timestamps. TRACE: used to retrieve the hops that a request takes to round trip from the server. Each intermediate proxy or gateway would inject its IP or DNS name into the Via header field. This can be used for diagnostic purposes. OPTIONS: used to retrieve the server capabilities. On the client-side, it can be used to modify the request based on what the server can support.
