In the context of wireless networks, what does the 'G' in '5G' represent?
Explanation: 'G' stands for 'Generation' in 5G, indicating it is the fifth generation of wireless technology standards. 'Gigabyte' is a unit of data, 'Global' might sound logical but isn't the standard meaning, and 'Graphics' relates to images and display, making them all incorrect in this context.
Which part of a personal computer is primarily responsible for executing instructions and performing calculations?
Explanation: The CPU, or central processing unit, is the brain of the computer, handling processing tasks. RAM temporarily stores data, the monitor is the display screen, and the mouse is an input device. Only the CPU directly executes program instructions and calculations.
What is the main function of a web browser in internet usage?
Explanation: A web browser's primary role is displaying websites and web content for users. Storing files is managed by file systems, creating spreadsheets is typically the job of productivity software, and editing photos requires dedicated graphic editing applications. These distractors are all tasks browsers do not directly perform.
