A mouse is a common input device that almost all computers use today. The primary function of the mouse is to detect 2 dimensional movements and translate that movement into motion of a pointer or display on a computer monitor which allows easy navigation of things such as a graphical user interface. A basic mouse consists of a right click button, a left click button and a scroll wheel. Depending on what is displayed on screen, these buttons can be used to interact with what is on screen e.g. using the scroll wheel to navigate up or down a web page that is being displayed on a monitor. The more advance mice (especially gaming mice) will most likely have more buttons on top of the standard set. This is so multiple functions can be bound to the mouse.
Modern day mice work using optical tracking technology. A miniature camera with an LED light takes thousands of photos a second and sends it to the complementary metal-oxide semiconductor (CMOS) sensor which then sends it to a digital signal processor (DSP) for analysis. The DSP detect the amount of change between each photo and determines the amount of movement and sends the coordinate to the computer. The connection between mouse and computer is usua...

... screen resolution (that being 4K), the future of screen resolution will continue to advance, resulting in higher quality display.

Memory: As memory becomes bigger, the physical size of the device that stores the memory is getting smaller. As we shrink down the size of the memory units, this will allow us in future to physically place in more things into our computers such as more RAM or a stronger video card. Shrinking of hardware as it becomes more powerful is essential to our future of hardware as we need to be able to fit more power into smaller devices.

HDMI: HDMI is another hardware size reduction, replacing traditional forms of connecting devices to displays. At the same time, it is able to connect and stream the data between the two devices at a higher quality. This advancement simply reduces size allowing more room for additional advancements on hardware.
