Question

1 what makes a computer qualify as a green pc?
it includes cloud - based software that automatically tracks the users carbon footprint.
it incorporates energy - efficient power supplies, low electricity use, recycled materials, and reduced environmental impact during its lifecycle.
it has the ability to recycle its own components automatically after disposal.
it operates on solar power exclusively and is built entirely from biodegradable materials.
2 what role does random access memory (ram) play in a computer?
it permanently archives files and user information for future retrieval during system reboots.
it temporarily stores active data that can be accessed quickly by the cpu, improving overall performance but losing data when power is turned off.
it encrypts files to prevent data theft during network transmissions and internet usage.
it serves as the main backup system that restores operating systems during emergencies.
3 what is a spreadsheet primarily used for in business?
it organizes and manipulates numerical data using rows and columns for calculations, graphs, and projections.
it provides graphic tools for designing advertisements and professional company logos with ease.
it enables users to compose letters, memos, and business contracts using templates and fonts.
it monitors operating system updates and tracks installation logs for it administrators

Explanation:

1. A Green PC focuses on environmental - friendliness. Energy - efficient power supplies, low electricity use, recycled materials, and reduced environmental impact during its lifecycle are key aspects. Cloud - based software tracking carbon footprint is not the main qualifier. A computer can't recycle its own components automatically after disposal in a practical sense, and operating on solar power exclusively and being built from biodegradable materials is too extreme for a general Green PC definition.
2. RAM (Random Access Memory) is a volatile memory. It temporarily stores active data for quick CPU access. Permanent archiving is done by non - volatile storage like hard drives. Encrypting files is a function of security software, and serving as a main backup system is not its role.
3. Spreadsheets are designed for numerical data handling. They use rows and columns for calculations, graphing, and projections. Graphic design for advertisements and logos is done by graphic design software. Composing letters etc. is a word - processing task, and monitoring OS updates is an IT administrative tool function.
