                                          NEW QUESTION # 107
                                          What is the name for computer code that humans can understand?

                                          Answer: D

                                          Explanation:
                                          High-level programming language is the term for computer code that humans can understand. In Information Technology, high-level languages are designed to be readable and closer to natural language and mathematical notation than the binary instructions used by hardware. Examples include Python, Java, C#, and JavaScript. High-level languages use keywords, structured syntax, and abstractions that allow programmers to focus on problem solving rather than on hardware-specific details like memory addresses and CPU registers.
                                          This improves development speed, reduces errors, and makes software easier to maintain. High-level code must be translated into machine language before it can run on a computer. This translation can occur through compilation or interpretation. Compiled language and interpreted language describe how code is executed, not whether it is human-readable. Machine language is the lowest-level code expressed in binary and is not easily understood by humans. Therefore, the correct answer for human-understandable code is high-level programming language.

                                          NEW QUESTION # 110
                                          Which type of communications media uses light waves to transmit data?

                                          Answer: A

                                          Explanation:
                                          Fiber optic communication uses light waves to transmit data. Here's how it works:
                                          1.Fiber Optic Cable Structure:
                                          oA fiber optic cable consists of a core made of glass or plastic, surrounded by a cladding layer.
                                          oThe core acts as a light guide, allowing light to travel through it by total internal reflection.
                                          oThe cladding layer ensures that the light remains within the core.
                                          2.Light Propagation:
                                          oWhen data needs to be transmitted, a light source (usually a laser or LED) sends pulses of light into the fiber.
                                          oThe light travels down the core, bouncing off the cladding due to total internal reflection.
                                          oAs a result, the light signal remains confined within the core.
                                          3.Advantages of Fiber Optics:
                                          oHigh Bandwidth: Fiber optics can transmit large amounts of data quickly.
                                          oLow Attenuation: Light signals experience minimal loss over long distances.
                                          oImmune to Electromagnetic Interference: Unlike copper cables, fiber optics are not affected by electromagnetic fields.
                                          oSecure: It's difficult to tap into fiber optic cables without detection.
                                          4.Applications:
                                          oInternet Backbone: Fiber optics form the backbone of the global internet, connecting continents.
                                          oTelecommunications: Used for long-distance phone calls and high-speed internet.
                                          oData Centers: Within data centers, fiber optics connect servers and storage devices.
                                          oCable TV: Many cable TV networks use fiber optics for signal distribution.
