At the most basic level, computers work by processing and storing data using electronic components such as transistors. These components manipulate binary code (0s and 1s) to perform calculations and execute instructions, allowing the computer to carry out tasks and run programs.

Not at all. Information is information. Oranising it makes it easier to manipulate or find, it does not alter the value of it.
Principal component analysis (PCA) is a statistical technique used to reduce the dimensionality of a dataset while preserving most of its variance. It does this by identifying the directions (principal components) in which the data varies the most. These components can be used to visualize patterns in the data and to identify the most important features.

It is a language that allows you to manipulate data in a database and write queries. SQL (Structured Query Language) is one of the most well known one.
To use a database, first design a schema to define the structure of your data. Then create tables to store data following the schema. You can then use SQL queries to manipulate and retrieve data from the database. Most databases also provide tools or APIs to interact with them programmatically.
The comparative forms of "suitable" are "more suitable" and "less suitable". The superlative forms of "suitable" are "most suitable" and "least suitable".
The major components of a database system include: 1. Data; which is the most relevant.2. The data structures used to store the data e.g tables, columns, views, packages.3. The languages used e.g data manipulation language, data definition language.4. The query used to get the information needed from the database.5. Reports (on the the information from the database).
The terms instance and database are closely related, but don't refer to the same thing. The database is the set of files where application data (the reason for a database) and meta data is stored. An instance is the software (and memory) that Oracle uses to manipulate the data in the database. In order for the instance to be able to manipulate that data, the instance must open the database. A database can be opened (or mounted) by more than one instance, however, an instance can open at most one database.
