Operating System Scheduling

Only one process can be active at any given moment. CPUs are incredibly fast; even brief processing periods yield significant results.

The Evolution of Judicial Systems Until 1978

Historical Background

The Middle Ages, spanning from the 5th century (fall of the Roman Empire in 476 AD) to the 15th century (conquest of Constantinople by the Turks in 1453), witnessed significant shifts in judicial systems. While some mark the end with the Reconquest and the Discovery of America in 1492, the period undeniably shaped legal frameworks.

Feudalism, the dominant system in Western Europe, underpinned economic, social, and political life. Government systems relied on bonds and obligations linking kings, lords, and vassals. Legislative, executive, and judicial powers were concentrated in the hands of the King or Lord.

Key Material Properties and Mechanical Resistance

Hardness is the measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied.

Strength is the ability to withstand forces without permanent change (e.g., breakage). Hardness is one type of strength, just like tensile and compressive strength.

The toughness of a material is the maximum amount of energy it can absorb before fracturing, which is different from the amount of force that can be applied.

Stiffness is the extent to which an object resists deformation in response to an applied force. The opposite of stiffness is elasticity—how far an object will stretch when pulled with a given amount of force.

• Hardness: Measures the pressure needed to cause
