The hierarchy of data size is as follows:

Bit
Byte
Field
Record

A bit is the smallest unit of data and can represent a binary value of 0 or 1. A byte consists of 8 bits. A field is a collection of related data elements, and a record is a collection of fields. So, in terms of size, a byte is larger than a bit, and a field and a record are composed of multiple bytes and potentially multiple fields, respectively

The term that does not describe the importance of data security is normalization.

Data security focuses on ensuring the confidentiality, integrity, and availability of data. The terms provided—availability, consistency, and integrity—are all related to aspects of data security:

Availability: Ensures that data is accessible and available when needed, without unauthorized disruptions.

Consistency: Ensures that data remains consistent and accurate across different parts of the system.

Integrity: Ensures that data remains accurate and unaltered throughout its lifecycle, preventing unauthorized or unintended modifications.

Normalization, on the other hand, is a database design technique used to structure data in a way that reduces redundancy and ensures efficient data storage and retrieval. While normalization is important for database design, it is not directly related to data security in the same way that availability, consistency, and integrity are.

The allocation and de-allocation of computing resources in a computer is the function of the operating system. The operating system is responsible for managing various hardware and software resources, including memory, processing power, storage, and input/output devices. It ensures that different applications and processes run smoothly by allocating resources as needed and de-allocating them when they are no longer required. Application software, browsers, and memory units may interact with the operating system, but the primary responsibility for resource management lies with the operating system.
