Database Management Systems

A Database Management System (DBMS) is software that is used to store, organize, manage, and retrieve large amounts of data efficiently and securely.
A DBMS allows users to create databases, insert data, update records, delete data, and generate reports.
It provides an interface between the user and the database to ensure data consistency and integrity.
DBMS software also supports security by managing user permissions and data access controls.
It uses Structured Query Language (SQL) for performing various operations on the database.
Examples of DBMS include:
1. MySQL — an open-source relational database management system widely used for web applications.
2. Oracle Database — a commercial, powerful DBMS used by large enterprises for handling complex and huge datasets.
Other examples are Microsoft SQL Server, PostgreSQL, and SQLite.
In summary, DBMS makes data handling organized, secure, and accessible for multiple users.

Cookies are small text files that websites place on a user’s computer or device when they visit a site.
These files store information such as login credentials, user preferences, and tracking data.
The primary purpose of cookies is to identify users, remember their preferences, and enable a personalized browsing experience.
For example:
- When you log in to a website, cookies can remember your session so that you don’t have to log in again every time you visit the page.
- Cookies also store data about your activities, such as pages visited and items viewed, which helps websites provide tailored content and advertisements.
- Some cookies track user behavior across multiple websites for targeted advertising.
In contrast:
- Plug-ins are additional software components that add features to an existing program (e.g., a Flash player).
- Add-ons are small software modules that add extra functionality to browsers, like ad-blockers or toolbars.
- Bookmarks are saved links to websites that users store in their browser for quick access later — they don’t track activity.
Thus, the correct answer for files that store temporary browsing data to personalize online experience is Cookies.
