Data Transmission Networks: Delays, Losses, and Tools
Fiber Types and Distances
Q20. What are the three types of fiber in use? What are the distances they can cover without needing repeaters?
A20.
- Multimode Step-Index Fiber:
- Copper: 2000 meters at 100 Mbps.
- Multimode Graded-Index Fiber: Covers 3000 meters at 100 Mbps.
- Singlemode Fiber: Up to 80km.
Repeaters and Hubs
Q21. What are repeaters and hubs?
A21. Repeaters strengthen the signal by repeating electrical signals, amplifying both the signal and any noise. Hubs distribute the amplified signal across all

The Data Science Process
Steps in the Data Science Process
The data science process involves a series of steps that help data scientists analyze and derive insights from data. While different organizations and individuals may have variations in their approach, the following steps provide a general framework for the data science process:
Problem Definition: The first step is to clearly define the problem or question you want to address with data science. This involves understanding the business or research
Medical Records: Evaluation, Digitization, and Outsourcing
5 Evaluation, Selection, and Destruction of Consignment Notes
The process of evaluation, selection, and destruction of the consignment note must be made prior to the migration to another medium. The healthcare world uses two different techniques: microfilming and digitization.
- Microfilming: The support is microfilm.
- Digitization: The supports are magnetic and optical discs.
Before making the change of support, the Health Care Center (HHCC) and having completed the weeding, should check that documents

Data Types and Basic Algorithms
1. Defining Data Types
Data types define the set of values a variable can hold and the set of operations that can be performed on that variable.
2. Primitive Data Types
Primitive data types can be divided into:
- Numeric: Integer and Real
- Alphanumeric: Character and String
- Logical: True or False
3. Primitive Instructions
- Input: Allows the user to provide data. Example:
READ(NUM) - Assignment: Stores information in a variable. Example:
X <- 5 - Output: Displays information to the
Understanding Non-Deterministic Algorithms and NP Complexity
Non-Deterministic Algorithms
A Non-Deterministic Algorithm is an algorithm that, when executed with the same input, may produce different outputs or follow different execution paths. This non-determinism can occur due to random choices, parallelism, or other factors that make the behavior unpredictable.
Key Features:
- Multiple Outcomes: The algorithm may have different results even for identical inputs, based on random decisions or execution order.
- Randomness: Often involves random choices or probabilistic
