Binary Logic: It is the language of computers, a series of electrical signals that work i 0's and 1's. These combinations are processed by the CPU and displayed onscreen |
Logic Gates: These are the building blocks of digital circuits that work in binary and have two inputs and one output |
|
|
Clock Speed: This is the speed the CPU can process data measured in cycles per second |
Cores: These are individual units that process data in the CPU. More cores means that a computer can process multiple amounts of data at a time but most software does not utilise multiple cores |
|
|
CPU: This is the 'brain of the computer'. They fetch, decode and execute information one instruction at a time to complete an instruction |
RAM: This is where small amounts of data are temporarily stored and can be accessed almost instantly by the CPU. |
|
|
ROM: It stands for 'read only memory' which is a non-volatile piece of memory that is used to store firmware as it's contents are difficult to modify |
Cache: This is where extremely small amounts of data are temporarily stored which can be accessed even faster that RAM memory. |
|
|
Volatile: Information or data that rapidly changes frequently |
Non-volatile: Information or data that does not change very often or not at all |
|
|
Lossy: It is where unnecessary data is discarded from the memory |
Lossless: It is where no data is discarded |
