The Basics of Computer Components by James Broadberry
What I will cover Processor RAM Hard Disk Drive Graphics Card Power supply Motherboard
Processor (CPU) Brain of the computer Controls everything that goes on Every piece of information will go through the processor. Every piece of logic is applied at the Processor Speed of the processor is how many times the information can “cycle” through the processor.
RAM Temporarily stores information Gets information to the processor without wasting/delaying clock cycles. When the computer is turned off, the data stored in the RAM is erased Adding more RAM will let more applications run faster
Hard Disk Drive (HDD) All files are stored on the Hard Drive Slower than RAM but can hold more, permanently The Operating System is stored on the Hard Drive
Graphics Card (GPU) Generates signals to be sent to the monitor/screen Amount of pixels generated depends on the speed of the GPU and screen size The rate that the pixels are “re-generated” or “refreshed” are measured in Hertz
Power Supply (PSU) Converts AC to DC Power supplies for standard workstations are normally output about 350 Watts Divide power up for safe use
Motherboard All of the computer components are connected to it Distributes power to the processor and RAM Sends information between the Processor and the RAM Gets between 30-40 degrees while doing nothing with correct cooling
What goes where?
Recap Motherboard connects every component to each other The processor does all of the logic RAM stored information temporarily at very high speeds Hard Drives store information permanently Graphics Cards are used to generate a signal to be read and understood by a monitor The power supply divides the power between each component
