Block I- Unit 1- Quiz 1

The statement is true because the description of what a piece of code does is indeed called its specification. The word "specification" refers to a detailed description or explanation of how something should be done or achieved. In the context of coding, a specification serves as a guide or reference for developers to understand the purpose and functionality of a particular piece of code. Therefore, it is accurate to say that the description of what a piece of code does is its specification.

The given answer "False, false" is correct because the statement "for (i = 0; i

The statement "In the event-driven model, the program derives the user" is incorrect. In an event-driven model, the program responds to events or actions initiated by the user or other sources, rather than deriving the user. The correct answer is false.

The statement is true. An algorithm is a step-by-step procedure or a set of rules that can be followed to solve a problem. It is a precise and systematic approach that can be implemented by a computer. Therefore, a method of solution that can be carried out by a computer is indeed referred to as an algorithm. The answer is true.

The given answer "False,false" is incorrect. The statement "Translate the program into a form that the machine can obey, this step is referred to as linking the program" is true. Linking the program is the process of combining multiple object files and libraries into a single executable file that the machine can understand and execute. Therefore, the correct answer should be "True".

Programming for embedded systems often follows an event-driven model approach. This means that the system generates events through interrupts, and the system responds to these events accordingly. Therefore, the statement "Programming for embedded systems can take the event-driven model approach; interrupt-driven generating events that the system responded to" is true. The answer "True,true" confirms the correctness of the statement.

The correct answer is int Age; float Price; float Salary; This answer correctly declares three variables: Age as an integer, Price as a float, and Salary as a float.

The correct answer is "Both a and b" because any computer system is composed of both computer hardware and computer software. Computer hardware refers to the physical components of a computer system, such as the processor, memory, and storage devices. Computer software, on the other hand, refers to the programs and data that run on the hardware, including the operating system and applications. Both hardware and software are essential for a computer system to function properly.

The correct answer is "All of the above" because the main hardware devices components of a computer include input devices, output devices, and storage devices. Input devices such as keyboards and mice allow users to input data into the computer. Output devices like monitors and printers display or produce the processed information. Storing data is done using storage devices like hard drives or solid-state drives. Therefore, all three options mentioned in the question are correct in describing the main hardware components of a computer.

The question is asking for the term that describes the way in which something achieves its purpose. The term "implementation" refers to the process or method of putting something into action or practice. Therefore, "How" is the correct answer as it aligns with the definition of implementation.

Main memory, also known as primary memory or RAM (Random Access Memory), holds programs temporarily during execution. It is a volatile memory that stores data and instructions that the CPU needs to access quickly. Main memory is directly accessible by the CPU and is faster than secondary memory (such as hard drives or SSDs). It provides the storage space for the currently running programs and data, allowing the CPU to quickly retrieve and manipulate information. Secondary memory is used for long-term storage, while cache memory is a smaller and faster memory that stores frequently accessed data to improve the CPU's performance.

A computer is a device that produces outputs. This means that it is capable of generating results, such as displaying information on a screen, printing documents, or producing sound. The other options, executing data and passing data, are not exclusive to computers and can be performed by other devices as well. Therefore, the correct answer is "Produces outputs."
