COSC Final Exam Study Guide 2

Explanation
CABLE provides the highest speed Internet connection compared to DSL, satellite, and dial-up. Cable Internet uses coaxial cables to transmit data, allowing for faster download and upload speeds. DSL uses telephone lines and typically offers slower speeds than cable. Satellite Internet relies on signals from satellites, which can introduce latency and slower speeds. Dial-up, on the other hand, uses a telephone line and offers the slowest speeds as it only allows for a limited amount of data to be transmitted at a time.

Explanation
The statement "The primary use for the Internet is searching" is false. While searching is a common and important use of the Internet, it is not the only primary use. The Internet is also used for various other purposes such as communication, entertainment, online shopping, social networking, information sharing, and much more. Therefore, the statement is not accurate as it oversimplifies the diverse range of activities and functions that the Internet serves.

Explanation
A URL (Uniform Resource Locator) is a reference to a web resource that specifies its location on a computer network. It consists of several parts, including the protocol (such as HTTP or HTTPS), the domain name (such as google.com), and the path to the specific resource. "Hyperlinks" are not a part of a URL but rather a feature within a web page that allows users to navigate to other web pages or resources by clicking on them.

Explanation
Podcasts use RSS (Really Simple Syndication) technology. RSS allows users to subscribe to a podcast and automatically receive new episodes or updates. It is a web feed format that enables content publishers to syndicate their content, including audio files, to be easily distributed and accessed by users. By using RSS, podcast listeners can stay updated with their favorite shows without manually checking for new episodes.

Explanation
RSS stands for "really simple syndication." This technology allows users to receive updates from their favorite websites or blogs in a standardized format. It simplifies the process of staying updated by aggregating content from multiple sources into a single feed. Users can subscribe to these feeds using RSS readers or news aggregators, enabling them to access new content without visiting each website individually.

Explanation
The first step of the system development life cycle is problem and opportunity identification. This involves identifying and understanding the current problems or opportunities that exist within an organization or system. It is important to identify these issues before moving forward with the development process, as it helps to set the direction and goals for the project. By identifying the problems and opportunities, the development team can then proceed to analyze and design solutions that will address these issues effectively.

Explanation
The design phase of the system development life cycle generates a detailed plan for programmers to follow. During this phase, the requirements gathered during the analysis phase are translated into a detailed design specification. This design specification outlines the architecture, components, and functionality of the system, providing clear instructions for programmers to develop the software. It includes details such as data structures, algorithms, user interfaces, and integration points. The design phase sets the foundation for the development phase by providing a roadmap for programmers to follow in order to build the system according to the specified requirements.

Explanation
The phase of the system development life cycle that explores the problem in depth and develops program specifications is the analysis phase. During this phase, the project team gathers and analyzes information about the current system, identifies the requirements and constraints, and determines the feasibility of the proposed solution. It involves understanding the problem thoroughly, identifying the root causes, and developing detailed program specifications that outline how the system will function and meet the identified requirements. This phase sets the foundation for the subsequent phases of design and implementation.

Explanation
Top-down design is a method of algorithm creation where a programmer starts by breaking down a problem into high-level tasks. Each task is then further broken down into more detailed subtasks. This approach allows for a systematic and organized way of solving complex problems by focusing on the overall structure and functionality before diving into the specifics. By breaking the problem down into manageable chunks, it becomes easier to understand and tackle each component, leading to a more efficient and effective solution.

Explanation
The final stage of the program development life cycle (PDLC) is debugging the code. This is the process of identifying and fixing errors or bugs in the program's code. After the code has been written and implemented, it is important to thoroughly test and debug it to ensure that it functions correctly and meets the desired specifications. Debugging helps to eliminate any issues or malfunctions in the code, ensuring that the program runs smoothly and efficiently.
