ROM stands for Read-Only Memory, which is a type of computer memory that stores data permanently and cannot be modified or erased. It contains instructions that are permanently written during manufacturing and remains intact even when the computer is powered off. This memory is used to store essential system software and firmware that is required for the computer to boot up and perform basic operations. Therefore, the given statement "True" is correct, as it accurately defines the acronym ROM.

RAM stands for Random Access Memory. It is a type of computer memory that allows data to be accessed in any random order, rather than sequentially. It is volatile memory, meaning that it requires power to retain data. RAM is used by the computer's operating system and software to temporarily store data that is actively being used, allowing for faster access and processing. The term "random access memory" is commonly written in lowercase letters as "random access memory" or "RAM".

The CPU (Central Processing Unit) is the component responsible for making calculations and executing logical operations in a computer system. It is often referred to as the "brain" of the computer, as it performs the majority of the processing tasks. The CPU interprets and executes instructions from the computer's memory, performs arithmetic and logical operations, and controls the flow of data between different components. Therefore, the CPU is the correct answer for the given question.

A compact disc is an example of an optical storage device because it uses laser technology to read and write data. The data is stored on the disc's surface as microscopic pits and bumps, which are then read by a laser beam. This technology allows for large amounts of data to be stored and retrieved quickly and efficiently. Unlike a hard disk or USB flash drive, which use magnetic or solid-state storage respectively, a compact disc relies on optical technology for data storage and retrieval.

The SMART Board is not an output device but rather an interactive whiteboard that functions as both an input and output device. It allows users to write, draw, and interact with digital content using a touch-sensitive surface. Therefore, the statement that the SMART Board is an output device is incorrect.

The ROM doesn't erase stored data (BIOS) when a computer turns off.

One example of implementation would be Direct Changeover. Direct changeover is a type of implementation strategy where the old system is completely replaced by the new system at a specific point in time. This means that the new system is implemented immediately and there is no overlap or parallel running of the old and new systems. It is a quick and straightforward approach, but it also carries higher risks and can be disruptive to the organization's operations.

The output devices that are categorized in the hardcopy section are LaserJet Printer, InkJet Printer, Plotter Cutter, and Dot Matrix Printer. These devices are all capable of producing physical copies of documents or images on various types of media, such as paper or transparencies. They use different technologies and have different printing capabilities, but they all fall under the category of hardcopy output devices.
