PC Support I-IV Final Exam

Explanation
Microsoft Word is considered to be software because it is a computer application that allows users to create, edit, and save documents. It is a program that runs on a computer and performs specific tasks, in this case, word processing. Unlike the other options listed, such as the monitor, memory chips, and mouse, Microsoft Word is a software program that provides functionality and allows users to interact with it to accomplish specific tasks.

Explanation
The central processing unit (CPU) is the primary component of a computer system that performs most of the processing inside the computer. It is responsible for executing instructions, performing calculations, and managing data flow between different parts of the computer. The term "microprocessor" is often used interchangeably with CPU, as it refers to the integrated circuit that contains the CPU's functions on a single chip. Therefore, the correct answer is Microprocessor.

Explanation
A CD-ROM is not considered to be primary storage because primary storage refers to the main memory of a computer system, which is typically made up of RAM (Random Access Memory) or cache memory. CD-ROMs are considered secondary storage devices as they are used for long-term storage and data retrieval, rather than for immediate access and processing of data.

Explanation
The file extension identifies the type of file. It is a suffix attached to the end of a file name, usually separated by a period. The extension indicates the format or structure of the file, allowing the operating system or software to understand how to handle and open the file.

Explanation
Device Manager is the primary Windows tool that can be used when solving problems with hardware. It allows users to view and manage all the hardware devices installed on their computer. With Device Manager, users can update drivers, disable or enable devices, troubleshoot hardware issues, and view detailed information about each device. This tool is essential for diagnosing and resolving hardware problems on a Windows system.

Explanation
The MBR (Master Boot Record) is a small section of a computer's hard drive that contains the master boot program and the partition table. The master boot program is responsible for loading the operating system, while the partition table keeps track of the different partitions on the hard drive. Therefore, the statement "The MBR contains the master boot program and the partition table" is true.

Explanation
A capacitor is an electronic device that can store and release electrical energy. It holds an electrical charge for a period of time and smooths the uneven flow of electricity through a circuit. When connected to a circuit, a capacitor absorbs excess electrical energy during periods of high voltage and releases it during periods of low voltage, helping to regulate the flow of electricity and maintain a steady current. This makes capacitors useful in a variety of applications, such as in power supplies, filters, and timing circuits.

Explanation
The primary cache is the memory cache on the processor chip. It is the closest and fastest cache to the processor and stores frequently used instructions and data for quick access. The primary cache, also known as level 1 cache, is smaller in size compared to other caches like level 2 or secondary cache, but it has the lowest latency and provides the fastest access to data. DRAM, on the other hand, is a type of memory used for main system memory and is not directly located on the processor chip.

Explanation
A PGA socket refers to a Pin Grid Array socket, which is a type of CPU socket used to connect a processor to a motherboard. The pins in a PGA socket are aligned in uniform rows around the socket, allowing for easy insertion and connection of the processor. This design ensures that all pins have equal access to the motherboard's circuitry, providing a reliable and efficient connection between the processor and the motherboard.
