Study Notes
Computer Hardware: The Physical Components of a Computer System
Computer hardware refers to the physical components of a computer system. These are the tangible parts that you can see and touch, such as the CPU, RAM, motherboard, graphics card, and power supply unit (PSU).
Motherboard
The motherboard is the backbone of a computer system. It acts as the central hub that connects and coordinates power across all other hardware components. When building or upgrading a computer, it's essential to consider motherboard compatibility, as it dictates which other hardware components can be used with your computer.
Graphics Processing Unit (GPU)
A GPU is responsible for processing graphical data. It connects with the motherboard via an expansion slot, allowing you to upgrade your graphics card for improved gaming, video, or visual performance. Modern GPUs also provide additional computational workload beyond just rendering, making them an extension of the central processing unit.
Power Supply Unit (PSU)
A PSU takes electricity from an external power source or laptop battery and passes it to the motherboard to power individual components. It's crucial to use a power supply with suitable wattage to effectively power all computer hardware.
Checking Hardware Specs
To check the hardware specifications of your computer, you can use tools like the Crucial System Scanner or the Crucial System Selector, which provide upgrade options compatible with your PC or motherboard. Alternatively, you can check your hardware through your settings or by physically checking the labels on the hardware components.
Types of Computer Systems
Personal Computer
Personal computers (PCs) are common due to their versatility and relatively low price. They include desktop and laptop models. Desktop PCs have a monitor, keyboard, mouse, and computer case, which holds the motherboard, storage drives, power supply, and other peripheral devices. Laptops are designed for portability and have a built-in keyboard, display, and processor in one case. They may use lower-power or reduced size components, with lower performance compared to desktop computers.
Sales and Recycling
In 2023, global revenue from computer hardware reached $705.17 billion. Due to the hazardous materials found in computer parts, there's a growing movement to recycle old and outdated hardware. Computer hardware contains dangerous chemicals such as lead, mercury, nickel, and cadmium, which have harmful effects on the environment without proper disposal. Recycling hardware reduces air pollution, water pollution, and greenhouse gas emissions.
