Service account, in few words, is an account by which rights and privileges some tool will perform its tasks.

So, in this case, when JENKINS server will try to do some builds or actually to perform any operation against operating system, it will use that service account. Technically speaking, service account is same like regular interactive accounts but it has its own specific purpose and in most cases it's not used for any other interaction.

Application (Programming) Language vs Scripting Language

https://www.programmingeeks.com/scripting-vs-programming-languages/

The compiled languages came to be known as programming languages and the ones that utilized an interpreter were known as scripting languages.

Scripting Language:
Interpreter based, no need to compile
Does not create a file type
JavaScript, PHP, Ruby, Perl, VB Script, etc.

Programming Language:
Compiler based ,needs to compile first
Creates a .exe file
C, C++, Java, Pascal, C#, VB, Basic, COBOL, etc.

Online IDE: https://repl.it/

BeanShell : Java light weight interpreter scripting language , used in JMeter

Cookies vs Sessions

Cookies are textual information created by server and stored on client machine only. Cookie can only be read from the domain that it has been issued from. For example, a cookie set using the domain www.guru99.com cannot be read from the domain career.guru99.com.

Most websites are having option to disable cookies, third party cookies or both.

Cookies Ex: Page visited information, User preferences, remembering username and password.

Session: sessions get stored on the client as well as a server. A session creates a file in a temporary directory on the server where registered session variables and their values are stored. This data will be available to all pages on the site during that visit.
Whenever a session is created, a cookie containing the unique session id is stored on the user’s computer and sends the session id with every request to the server.

If the client browser does not support cookies, the unique session id is displayed in the URL.The session values are automatically deleted when the browser is closed.

Key Differences:

Cookies are client-side files that contain user information, whereas Sessions are server-side files that contain user information.
Cookie is not dependent on session, but Session is dependent on Cookie.
Cookie expires depending on the lifetime you set for it, while a Session ends when a user closes his/her browser.
