While there are many different components that make up a computer, there are a few we talk about most when troubleshooting and understanding how our scholars use technology.
CPU (Central Processing Unit)
The CPU is responsible for interpreting and executing most of a computer's commands or actions. If a computer is a person, the CPU is the brain. The speed or power of a CPU is measured in GHz (gigahertz).
A clock speed of 1Hz means 1 process for every second. A clock speed of 3.0GHz means 3 billion processes every second.

Hard drive storage comes in several different formats and configurations. The most important and practical information regarding hard drive storage is understanding how much space it has. Hard drives, by default, do not have any backups or clouds to sync to (unless otherwise set up). This means that if a file is stored on a local hard drive, it only exists on that physical hardware by default.
How it's measured: Hard drive storage space is measured in bytes or more commonly GB (gigabytes) and/or TB (terabytes). It's important to note that 1GB of hard drive space is different than 1GB RAM.
Hard drives are sometimes called the "C Drive" in conversation due to the default letter assigned to a drive is often "C." (Drives can be assigned any letter.)
RAM (Random Access Memory)
RAM is responsible for holding temporary or "working memory." RAM works with your computer's hard drive but had a different function. RAM memory is like an office desk in that it allows a workspace and quick access to documents and other tools. Hard drive space is like the filing cabinet within an office desk that holds important documents, files, and information.
How it's measured: GB (gigabytes) It's important to note that 1GB of RAM is different than 1GB of hard drive space.
Many computers have connectivity capabilities allowing the device to communicate outside of its own system. Connectivity includes technology such as using a Wi-Fi adapter to connect to a network, a Bluetooth transmitter to communicate to nearby peripherals.
