Digital simulation is a method of investigating real phenomena, processes, devices, or systems that is based on the study of mathematical models with the aid of digital computers.
The program executed by the computer is also a kind of model of the subject of the investigation.
Coding is how we communicate with computers. Code tells a computer what actions to take, and writing code is like creating a set of instructions.
By learning to write code, you can tell computers what to do or how to behave in a much faster way.
Virtual reality is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality include entertainment, education and business .
Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR.
Networking cables are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printers, scanners etc.
Different types of network cables, such as coaxial cable, optical fiber cable, and twisted pair cables, are used depending on the network’s physical layer, topology, and size.
There are several technologies used for network connections.
Patch cables are used for short distances in offices and wiring closets. Electrical connections using twisted pair or coaxial cable are used within a building. Optical fiber cable is used for long distances or for applications requiring high bandwidth or electrical isolation.
Graphic card is an expansion card which generates a feed of output images to a display device (such as a computer monitor).
Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics.
At the core of both is the graphics processing unit (GPU), which is the main part that does the actual computations, but should not be confused with the video card as a whole, although “GPU” is often used as a metonymic shorthand to refer to video cards.
Projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen.
Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers.
A virtual retinal display, or retinal projector, is a projector that projects an image directly on the retina instead of using an external projection screen.
The most common type of projector used today is called a video projector.
