Absolute
Traditionally understood in philosophy as that which exists by itself, independent of anything else. When referring to truth, it signifies complete and total truth.
Abstract, Abstraction
Etymologically, abstract means to extract, to make something out of something, or to remove something from something. In a strict sense, abstraction is the process by which the understanding obtains (extracts) the universal concept from a sensory image, which is particular and concrete. The concept of “house”

Porifera and Coelenterata
Porifera, such as sponges, and Coelenterata, such as jellyfish and polyps, were once thought to be plants because they are often found fixed to a rocky or sandy substrate.
Porifera (Sponges)
The body of a sponge is shaped like a bag and is perforated by numerous pores, which communicate through its interior canals. The main cavity communicates with the outside through a hole called the osculum.
Coelenterates
- Medusa: Umbrella-shaped with an opening at the bottom. They live floating
Eukaryotic Cells: Structures and Functions
Mitochondria
Mitochondria are organelles surrounded by two membranes, present in all eukaryotic cells. They are considered the power plants of the cell since they are the site of the oxidation of fatty acids and the aerobic phase of cellular respiration.
- Outer membrane: Smooth and permeable.
- External chamber: Located between the two membranes, with a composition very similar to the cytosol because of the permeability of the outer membrane.
- Internal membrane: Presents a series of folds directed toward

Understanding the Role of the Linux Kernel in the Android Software Stack
The Linux Kernel plays a central role in the Android software stack as the foundation layer that interacts directly with the hardware and provides basic services for all other software layers above it. It handles tasks such as memory management, process scheduling, device drivers, and hardware abstraction, which are essential for running applications and services in Android.
