182. What is the main job of the central processing unit (CPU) in a computer?

Correct Answer: Correct answer is: (A) It executes the instructions from a program stored in memory.

Exam Relevance: SAT, ACT, AP Computer Science Principles

Difficulty: Easy

Concept notes: The central processing unit (CPU) is the primary component of a computer that performs most of the processing tasks. It executes instructions from a program stored in memory.

Common Mistakes: Students may confuse the CPU with the memory (RAM), which stores data and instructions, or with the bus system, which transfers data between components.

Explanations: The CPU is responsible for executing instructions from a program stored in memory. It fetches instructions from memory, decodes them, and executes them. This process is fundamental to how a computer operates and performs tasks.

Option Analysis:

Option A: Correct. The CPU executes instructions from a program stored in memory.
Option B: Incorrect. This describes the function of memory (RAM), not the CPU.
Option C: Incorrect. This describes the function of the bus system, not the CPU.
Option D: Incorrect. This is not applicable as one of the other options is correct.

183. MLA format recommends that use footnotes to provide a few short words about the resource and the author(s) within the document. What do you use to detail the resource, including authors, publishers, date of publications or copyright, web address and pages used?

Difficulty: Easy

Concept notes: The Physical layer is the lowest layer of the OSI model and is responsible for the transmission and reception of raw bit streams over a physical medium.

Common Mistakes: Students often confuse the Physical layer with the Data Link layer, which is responsible for error-free transmission of data frames.

Explanations: The Physical layer is the first layer to receive a message from another device because it is responsible for the physical transmission of data over the network medium. It handles the electrical, mechanical, and procedural interfaces to the network medium.

Option Analysis:

Option A: The Data Link layer is responsible for error-free transmission of data frames, not the initial reception of raw bit streams.
Option B: The Application layer is the highest layer and deals with user applications, not the initial reception of data.
Option C: The Physical layer is the first layer to receive a message from another device as it handles the physical transmission of data over the network medium.
