Liquid crystal display (LCD)
It produces images by allowing or blocking light to pass through.
Liquid crystals rotate polarized light.
A polarizing glass filter is placed in front of and behind the pixels which are turned on and off electronically.
LCD displays use three technologies: twisted nematic (TN), vertical alignment (VA) panels, and in-panel switching (IPS).
Twisted nematic technology
TN technologies were used in early LCD. They use low operating voltages making their use with batteries possible. They are still used for monochrome alphanumeric displays.
Vertical alignment
VA was used in the early adoption of color LCD. It produces a truer black and offer a wider viewing angle. A downside is distortion when transitioning colors.
In-plane switching
IPS has a high response rate. This is the technology used in LCD televisions and displays. It is the best choice for use on touchscreen displays.
Organic light-emitting diode (OLED)
CISC
Complex instruction set.
RISC
Reduced instruction set. These chips are smaller than CISC and produce less heat. which is why they are used in phones. However they do use more memory is takes more coding to complete a task with RISC.
x64 CPU
It is a processor that has higher performance and is faster. it is the newest architecture for 64-bit computing, enabling better performance and efficiency than previous generations. supports 64-bit computing and has access to more than 4GB of RAM
x86
This older processing architecture supports 32-bit computing and was widely used in earlier personal computers. It offers compatibility with a wide range of software and is limited to 4 GB of RAM.
ARM
advanced RISC machine. It is a competing technology to the x64 intel and AMD processors. the have an x64 implementation.
