Understanding Key Political and Economic Concepts
Militarism
Militarism is an ideology that posits military force as the source of security. In its mildest form, it uses various arguments to justify military preparedness, assuming that “peace through strength” is the best or only way to achieve peace.
Tariffs
A tariff is a tax on imported or exported goods. Tariffs can be “ad valorem” (a percentage of the value) or “specific” (a set amount per unit). They are used to generate governmental income or protect domestic industries. Essentially, a tariff

International Law
International law is the collection of international agreements on legal grounds, the laws of the states, and other international law subjects represented by their supreme courts. It includes treaties, international customs, general law principles, and agreements within international organizations. States commit to enforcing these standards within their territories, prioritizing them over national standards. Traditionally, international law is divided into public and private international

Soviet Influence in Eastern Europe
After WWII, the Soviet Army occupied Eastern Europe. In Bulgaria, Poland, Czechoslovakia, Romania, Hungary, and Albania, communist governments aligned with the USSR were established. Coalitions, often including communist and socialist parties, initiated communist reforms. Albania’s Popular Front won the 1945 election. Czechoslovakia experienced a communist government takeover after the Prague coup. Bulgaria abolished its monarchy. In Poland, communists and socialists

Modern Argentina
Oligarchic Regime (“Conservative” Government)
Government based on an elite of notables (intellectually prepared and economically powerful).
The elite ensured its hold on power in two ways:
a) Control of Succession: Complex, involving a small group of notables (e.g., president, senators, provincial governors).
b) Electoral Fraud: Intimidation of opponents, pressure on voters, ballot manipulation, double voting, voting by the deceased, etc.
“The Generation of 80”

Chromosomal Alterations
Structural Alterations
These affect the structure of chromosomes, impacting gene location. They are usually caused by errors in mitosis and meiosis, mainly affecting homologous chromosome pairing during prophase I. There are four types:
- Deficiencies or Deletions: Loss of a chromosome segment, affecting multiple genes. Example: Cri du chat syndrome.
- Duplications: Repetition of a chromosome segment, often in heterozygous series. Cytologically recognized during mating as a duplicated
Computer Architecture, Systems, and Software Components
Processor Speed
MIPS (Millions of Instructions Per Second): A unit of measurement for computer speed.
System Clock: An electrical pulse synchronizes processing. 1 MHz = 1 million cycles per second. Higher frequency means faster processing.
BUS-Width: The amount of data the CPU can transmit at any time to main memory and input/output devices.
Data and Memory
Data:
- Input Data
- Output Results
- Internal Values (Processing Information/Program Instructions)
RAM (Random Access Memory): User’s working memory
