TEACHING STUDENTS COMPUTER HARDWARE AND SOFTWARE APPLICATION

Computer Hardware and Virtual Environment Generation Software Computer technology enables us to create 3D Virtual Environments (VEs) which is made up of both hardware and software. The technical and scientific interest in VEs is largely influenced by the emergence and accessibility of visually focused, interactive, graphical display systems and methods that are increasingly potent and inexpensive. Each hardware involves physical characteristics that are any component you can see or touch, such as: screen, case, keyboard, mouse, and printer. The portion that activates the software is called physical parts. It involves the characteristics that direct the job to the hardware, meaanwhile, in programs and information, software can be split.

In contrast to the physical parts of the scheme (hardware), software is a program that allows a computer to perform a particular job. This involves application software such as a word processor that allows a user to conduct a job, as well as system software such as an operating system that allows other software to operate correctly, interfacing with hardware and other software. Practical computer systems split software into three main groups: system software, software programming, and software application, although the difference is arbitrary and often blurred.

Computer software must be “loaded” into the storage of the computer (like a hard drive, memory, or RAM). Once the software is loaded, the software can be executed by the computer. Computers work by running the program of the computer. This includes passing commands from the application software to the hardware that eventually gets the instruction as machine code through the system software. Each instruction leads the computer to perform an operation, shifting information, performing a calculation, or changing instruction control flow.

Components of hardware

Let’s begin with the case of the laptop, so this is the metal enclosure containing many of the other parts of the hardware. It comes in different forms and sizes, but between 15-25 inches high is a typical tower model. However, the best way to learn, if you’re really in computers, is to simply get hands-on computer hardware concept experience and the metal side panel is substituted by a computer enthusiast with a transparent one. But recognizing the individual parts is a bit difficult, particularly with all the connecting cables running through it. Students learn more efficiently from lessons designed to involve themselves actively in practical operations.

An example is a teacher who shows a project to the student in a practical class to illustrate the theoretical ideas of bits, bytes, and a binary sequence counter. The students acquire fundamental understanding of the binary number system through active involvement in the demonstration and hands-on operations.

For the power supply of hardware components  and internal PC connections:

1. The energy supply converts the alternating present (AC) from your energy supply (110V input or 220V input) into the direct present (DC) required by your computer.

2. The energy supply in a PC is the metal box that is generally found in a corner of the case. The energy supply from many devices is noticeable from the back as it includes the energy cord receptacle and the cooling fan. Power supplies-often referred to as power supplies for switching, use switching technology to convert AC input to lower DC voltages.

Typical voltages generated are: •3.3 volts, •5 volts, •12 volts Case: a computer case (also known as a computer chassis, cabinet, box, tower, enclosure, housing, system unit or simple case) is the enclosure that includes most parts of a computer (generally excluding screen, keyboard and mouse). If you’re constructing your own computer, choosing the case will be one of your first decisions to make: case type, size, orientation, amount of bays you’ll need, etc.

Motherboard: the motherboard is the main circuit board that holds the computer’s vital processing components. It enables you to obtain energy from all components of your computer and interact with each other. Usually it is attached to the case along its biggest face, which based on the shape factor and orientation could be the bottom or side of the case. The form factor defines the motherboard’s shape and design. It influences where parts go and the shape of the case of the computer and the CPU is directly attached to the motherboard.
