Digital Environments

Chassis

Aesthetics - It is more pleasing on the eye to look at a computer chassis instead of a motherboard with wires and components.

Noise reduction - Many computers and their components require fans to keep everything cool and running properly. These fans can obviously generate noise. Having these all placed inside the chassis can reduce noise

Cooling - The chassis helps to keep the air flowing through the system and across the components. This helps to keep everything cool so that it will run properly.

Protection - Components are very sensitive and can be damaged easily. They are vulnerable to dirt, foreign objects, for example paper clips, and electrical interference. It is important that the components are protected at all times.

Optical Drive

This is a computer disk drive that reads and writes data from optical disks such as CDs and DVDs using laser beaming technology. (Pits and Lands). An optical is sometimes referred to as an optical disk drive (ODD). Although an optical drive can be used to read and write data, it is mainly used as an input device.

Motherboard

Motherboards have different form factors (size, shape) and are the main printed circuit board within a computer and contain the buses. Components such as the CPU, heatsink and fan assembly, RAM, etc are all located on the motherboard. The motherboard store the bios (Basic input output system)

Central Processing Unit

The central processing unit is the electronic circuitry within a computer system that carries out the instructions of a computer program by performing the arithmetic, logic, control and input/output. operations that are specified in the instructions it receives. 

Random Access Memory

Random access memory (RAM) is sometimes referred to as main memory, primary memory or system memory. It is a hardware device that allows information to be stored and retrieved on a computer system. The data is accessed randomly in the same way as data is accessed from a CD or Hard drive. This means that access times are much faster. However, RAM is known as volatile memory and the data is only available if there is power to the system.


Read Only Memory

Read only memory by its name is read-only meaning that you can only read the data that is stored on it. The ROM stores the bootstrap which holds the data to start the machine.

Graphical processing unit

The graphics processing unit is an electronic circuit used to speed up the creation of both two-dimensional and 3D images. They can either be integrated or dedicated

Project Aim and Objectives & Scope Activity Sheet   Project Name: Gloscol VR Project   Date: 28.2.2025     1. Defining the Project Aim   The project aim outlines the broad goal or purpose of the project. It should capture the overall vision and answer the question, “What is the main purpose of this project?”   Questions to Consider     What is the overall goal of this project?     To create a virtual tour of the college that can be viewed on VR as well as a desktop or phone.       What problem is this project solving or what opportunity is it creating?     We need to mak e it easier for people to see the college through a VR lens specifically those who cannot entire the college. Or can’t attend open evenings       Who will benefit from this project (stakeholders, customers, team members)?     The main stakeholders of the project are the potential students coming to the college w...

Global RTS The trip was in the morning on the 28th March 2025, Will and Patrick organised it. The purpose of the trip was to gain experience in the aviation industry, specifically air traffic control, using a simulator. We were shown how there simulators work and we were shown how to use them as well as being able to communicate using the aviation alphabet. We met people who worked there, learning how to become an air traffic controller. We used there main sim that used 4 big TVs to show a graphically simulated view of a run way from the view of a tower. We also communicated with headsets to simulate how real air traffic controllers communicate to pilots.
