Storage Devices

Storage Devices: devices that store information. They comprise:

Magnetic Disks

Magnetic disks: Hard drives, floppy disks have large capacity, non-volatile random access, but live slower. It is a closed box, partly comprising:

• Platters: Stored information resides here.
• Head: Reads and writes on the platters.
• Motors: Spin the platters and move the heads.

Components of Magnetic Disks

Platters: Glass, ceramic, or aluminum; joined by a shaft and a motor to rotate at 3600 and 7200 rpm, with a diameter of 5.5 inches.

Heads: Magnetic sensor that reads the charge and a magnet to change the charges for writing.

Spindle (Topic): Support for the disks.

Actuator: The motor that moves the heads.

Structure and Organization

Tracks (Structure-Runs): Concentric... Continue reading "Understanding Computer Storage Devices and Media" »

The Sign: Definition, Function, and Value

The sign has different functions. One primary function is identification, which requires the sign to call upon and re-present the object identified.

Furthermore, the sign possesses value; that is, the sign is worth what it means or represents. The word itself has value, even if it is not used to express something specific.

The sign is an object that represents the idea of another object. It is also defined as a minimum unit that lends meaning to an object within a given culture. The heritage of a culture is composed of all the universes of meaning—the signs that shape that culture.

Components of the Sign

The sign consists of two essential parts:

• Shape: What is seen or perceived through the senses (the signifier)

Banking Services

Characteristics

Banking services are activities undertaken by a bank at the request of its customers, satisfying a need. Their price is called a commission.

Differences from Goods

• Intangibility: Services cannot be perceived by the senses. You do not know if a service is expensive or not until it is used.
• Inability to Protect with Patents: Services cannot be patented; only the name is patented (e.g., Visa).
• Perishability: If a service is not used, it is lost.
• Impossibility of Appropriation: Purchase only grants the right to use the service, not ownership.

Debits

Debits are authorizations given to the bank to make collections and payments from a bank account.

• Collections: Payroll, pensions, broadcast collections.
• Payments: Utilities (electricity,

Dermis

The dermis is the part of the skin located below the epidermis, separated by the dermoepidermal junction. It is the connective tissue that holds the epidermis and contains the skin's nerves and sensory receptors. It is formed by a complex network of fibers embedded in a fundamental substance with few of its own cellular elements.

Function

• Provides resistance and flexibility to the skin.
• Acts as a protective barrier against internal agents, thus preventing infections.
• Serves as a reservoir for liquids.
• Stimulates the production of keratinocytes through keratogenesis.
• Participates in wound healing.

Structure

Papillary Dermis

This layer has a greater proportion of reticular fibers that participate in the dermoepidermal junction. Its function is to... Continue reading "The Dermis, Hypodermis, and Essential Skin Functions" »

Understanding Key Fishing Methods and Equipment

The world of fishing encompasses a wide array of techniques, each designed for specific purposes, target species, and environments. From highly selective methods to broader capture systems, understanding these approaches is crucial for both commercial and recreational anglers. Below, we detail some of the most common and historically significant fishing methods:

Longline Fishing

Longline fishing is considered one of the most selective fishing methods available. Depending on the bait and hook size used, it allows for targeting specific catch sizes or species. This precision makes it a preferred method for certain fisheries.

Purse Seine Fishing

As its name suggests, purse seine fishing involves surrounding... Continue reading "Essential Fishing Methods and Gear Explained" »

Families and Households in the Economy

Families or households are primarily responsible for consumption. They make decisions about which consumer goods and services to choose to satisfy their needs. Their ability to spend depends on their income.

The circular flow of income describes the continuous flow of payments for goods and services between households, companies, and the public sector.

The Role of the Public Sector

The public sector consists of various public authorities operating at typically three levels of government:

• Local government: City councils and provincial bodies.
• Regional government: Autonomous regional administrations.
• Central administration: National government, ministries, etc.

The public sector uses several instruments to conduct... Continue reading "Economic Fundamentals: Families, Government, and Systems" »

Core National Economic Indicators

• GDP (Gross Domestic Product): Monetary value of all goods and services produced within a country in a given period.
• GNP (Gross National Product): Determines the total income produced by all nationals (e.g., Spanish) worldwide.
• NNP (Net National Product): A nation's total output less the amount required to maintain the value of its capital stock (depreciation).

Factors Influencing Consumption and the Multiplier

Consumption Determinants

• Disposable income (annual)
• Permanent income (Life-Cycle Hypothesis)
• Wealth effect

The Multiplier Effect

The total increase in expenditure (K increment) experienced by the whole economy resulting from an increase in investment.

Macroeconomic Policy Objectives

1. Economic and Sustainable Growth:

Legitimacy of the State and the Definition of Law

The legitimacy of the state's action is to defend peace, values, and characteristics of democracies.

Understanding Law: Three Perspectives

Law can be understood in three ways:

1. Science: The study of law through its history, philosophy, and sociology.
2. Subjective Power: The effective power a member of society has to possess, make, or demand something, according to the laws and the legal system that protects them.
3. Objective: The set of laws and regulations governing the conduct of people and directing their lives in society.

Key Characteristics of Law

Law has the following characteristics:

1. Rationality: Law must have its foundation in reason, far from any arbitrary whim.
