Questions and Answers

What is the essential advantage of a computer when it comes to processing information?

The essential advantage of a computer is its ability to process large quantities of information automatically, at high speed and in excellent conditions of security.

What is the primary challenge that arises when the amount of information to be processed becomes very large?

  • Unfamiliar data formats
  • Ambiguous object designation (correct)
  • Limited processing power
  • Lack of storage capacity

    • What is codification?

    Codification is the procedure for assigning codes to objects. It aims to solve the problem of ambiguous identification by using a unique code for each object.

    Coding, as a process, is about replacing information with a conventional symbol that aligns with the user's objectives.

    Explain the concept of flexibility in the context of coding.

    <p>Flexibility refers to the ability of a code to adapt to changes in the data over time, such as expansions or insertions. In essence, a flexible code remains relevant and functional even as the information it represents evolves.</p> Signup and view all the answers

    What is the importance of ease of use in a code?

    <p>Ease of use encompasses various factors, including conciseness, ease of control, and ease of operation, making it easier for users to understand and apply the code.</p> Signup and view all the answers

    What is sequential coding?

    <p>Sequential coding assigns consecutive numbers to objects in a set, often based on chronological order.</p> Signup and view all the answers

    What is tranche coding?

    <p>Tranche coding divides the set of objects into categories and allocates ranges of codes to each category. Within each category, codes are usually sequential.</p> Signup and view all the answers

    What is articulated coding?

    <p>Articulated coding breaks down a code into multiple zones, each with a specific meaning. This allows for flexibility and can be used to represent complex information.</p> Signup and view all the answers

    What is level or hierarchical coding?

    <p>Level coding uses different levels or zones to create relationships between different sets of objects. Each level represents a set of objects, becoming increasingly specific as you move from left to right.</p> Signup and view all the answers

    What is mnemonic coding, and what are the two main types?

    <p>Mnemonic coding uses abbreviated forms of the object designation to create a code that is easy to remember. The two main types are consonant codes and abbreviative codes.</p> Signup and view all the answers

    Why is coding a key stage in the preparation of information?

    Study Notes

    Codification of Information

    • Codification is the procedure for assigning codes to objects, making it easier to process information automatically.
    • It's crucial when dealing with large amounts of information because it provides a clear and unambiguous way to identify and distinguish objects within a set.
    • Codification improves processing speed and security.

    Objectives of Codification

    • Understanding the concept of codification
    • Knowing different types of coding
    • Applying learned concepts to practical instances

    Definitions and Examples

    • Definition 1 (Coding): Replacing information in its natural form with a conventional symbol (code) to improve usability and automation.
    • Definition 2 (Code): A shortened representation of an object.
    • Example: Assigning codes to students: Year of entry to university + sequential number (e.g., 201900154).

    Codification Objectives

    • Uniquely identify individuals within a group.
    • Save space and time.
    • Illustrate specific characteristics of an object.
    • Facilitate formal information controls.

    Qualities of Codification

    • Uniqueness: Codes must be distinctive to identify an object.
    • Flexibility and longevity: The codes should be adjustable and viable for long-term use.
    • Ease of use: The code should be simple to use, concise, and easy to manage.

    Different Types of Coding

    • Sequential coding: Assigning consecutive numbers to objects in a set based on a chronological order (e.g., employee recruitment numbers).
    • Tranche coding: Dividing objects into categories with specific code ranges within each category, ensuring a sequentially ordered set of numbers within each tranche. In this, codes are generally sequential.
    • Articulated coding: Dividing codes into multiple zones (levels), each having a unique purpose. This approach is valuable when there exists a hierarchical relationship between different objects.
    • Level (Hierarchical) coding: Used for inclusion relationships: code is segmented into levels, representing successively smaller sets, from general to specific.

    Conducting Coding Operations

    • Define the population to be coded (type, number, and growth).
    • Study statistical breakdowns (necessary).
    • Check availability of existing codes from other organizations.
    • Verify the stability of coding criteria.
    • Involve those who will use the code in its design.
    • Create instructions and conduct testing with users (for successful implementation).
