What determines a monitor’s resolution?
A monitor’s resolution is determined by the number of distinct pixels in each dimension that can be displayed. It’s usually quoted as width × height, with the units in pixels. For instance, “1920 × 1080” means the width is 1920 pixels and the height is 1080 pixels. Here’s what mainly influences a monitor’s resolution:
Panel Size and Type: The physical size of the monitor and the technology behind the panel (like LCD, LED, OLED, etc.) can impact how densely pixels can be packed together, hence affecting resolution.
What is the main component of a system unit?
The main component of a system unit in a computer is the motherboard. It serves as the central platform that connects all the components of the computer together, including the CPU (Central Processing Unit), RAM (Random Access Memory), storage devices (like SSDs and HDDs), and expansion cards (such as graphics cards, network cards, and sound cards).
What is another name for an OS?
Another name for an Operating System (OS) is “platform” or “operating environment.” These terms are often used interchangeably to describe the system software that manages hardware and software resources on a computer, provides common services for computer programs, and enables the user interface and application software to interact with hardware components. The term “platform” is particularly common when discussing the base software environment in contrast to the applications that run on top of it.
