Hardware: External or internal devices and equipment that help you perform major functions
CPU: Central processing unit
Clock wire: When you send or receive data, it sends a voltage to that clock wire to let the CPU know it can start doing calculations
Clock cycle: When you send a voltage to the clock wire
Clock speed: The maximum number of clock cycles that it can handle in a set in a certain time period
Overclocking: It increases the rate of your CPU clock cycles in order to perform more tasks
Address bus: Connects the CPU to the MCC and sends over the location of the data, but not the data itself
Memory controller chip (MCC): A bridge between the CPU and the RAM
CPU sockets: A CPU socket is a series of pins that connect a CPU's processor to the PC's motherboard
Land Grid Array (LGA): It is a type of CPU socket that stick out of the motherboard
Pin Grid Array (PGA): CPU socket where the pins are located on the processor itself
Heatsink: It is used to dissipate heat from our CPU
Thermal paste: A substance used to better connect our CPU and heat sink, so the heat transfers from to the other better
Instruction set: A list of instructions that our CPU is able to run
Hard drive: It is a long term memory component that holds all of our data, which can include music, pictures, applications
ATA: The most common interface that hard drives use to connect to our system
HDD (Hard disk drive): Hard drive that uses spinning platter and mechanical arm to read and write information
SATA: The most popular serial ATA drive, which uses one cable for data transfers
SSD: Solid State Drive
Reimaging: The process of reimaging involves wiping and reinstalling an operating system using disk image which is a copy of an operating system
Motherboard: The body or circulatory system of the computer that connects all the pieces together
BIOS (Basic Input Output Services): The BIOS is software that helps initialise the hardware in our computer and gets our operating system up and running
Form factor: A mathematical way to compensate for irregularities in the shape of an object by using a ratio between its volume and height
ATX (Advanced Technology eXtended): The most common form factor for motherboards
ITX (Information Technology eXtended): A form factor for motherboards that is much smaller than ATX boards
Northbridge: Interconnects stuff like RAM and video cards
ROM chip (Read Only Memory): A read-only memory chip where the BIOS is stored
Southbridge: It maintains our IO or input/output controllers, like hard drives and USB devices that input and output data
Backwards compatible: It means that older hardware works with newer hardware
BYOD (Bring Your Own Device): Refers to the practise of allowing people to use their own personal devices for work
Cache: The assigned stored location for recently or frequently accessed data; on mobile app it is where anything that was changed or created with that app is stored
Charge cycle: One full charge and discharge of a battery
Chipset: It decides how components talk to each other on our machine
Data sizes: Metrics that refer to data sizes including bit, byte, kilobyte, kibibyte, and megabyte
MB/s: megabit per second, which is a unit of data transfer rate
RAM: Random Access Memory
DRAM: Dynamic Random Access Memory
SDRAM: It stands for Synchronous DRAM, this type of RAM is synchronised to our systems' clock speed allowing quicker processing of data
DDR SDRAM (Double Data Rate SDRAM): A type of RAM that is faster, takes up less power, and has larger capacity than earlier SDRAM versions
Desktop: The main screen where we can navigate our files, folders, and applications
DIMM: Dual Inline Memory Module
Display port: Port which also outputs audio and video
Drivers: The drivers contain the instructions our CPU needs to understand external devices like keyboards, webcams, printers
Cable
DVI: DVI cables generally just output video
HDMI: A type of cable that outputs both video and audio
Electrostatic discharge: a sudden and momentary flow of electric current between two electrically charged objects caused by contact, an electrical short or dielectric breakdown
External Data Bus (EDB): It's a row of wires that interconnect the parts of our computer
Factory reset: Resetting a device to the settings it came with from the factory
Connectors
Mobile
One of the standard power, data and display connector types used in mobile devices
Micro display port
Lightning adaptor
Micro HDMI
Micro USB
Mini HDMI
Mini USB
Type-C connector: A type of USB connector meant to replace many peripheral connections
USB (Universal Serial Bus): A connection standart for connecting peripherals to devices such as computers
USB-C adapter: One of the standard power, data and display connector types used in mobile devices
NVMe (NVM Express): interface standard which allows greater throughput of data and increased efficiency
PCI Express: Peripheral Component Interconnect Express
Peripherals: The external devices which we connect to our computer that add functionality, like: a mouse, a keyboard, and a monitor
Ports: Connection points that we can connect devices to that extend the functionality of our computer
POST (Power On Self Test): It figures out what hardware is on the computer
Power supply: Converts electricity from our wall outlet AC onto format that our computers can use DC
Programs: Basic instructions that tell computer what to do
Registers: An accessible location for storing the data that our CPU works with
Return merchandise authorisation (RMA): The process of receiving returned merchandise and authorising a refund
RPM: Revolutions per minute
Safe operating temperature: The temperature range in which rechargeable batteries must be kept in order to avoid damage
SOC (System On a Chip): Packs the CPU, Ram, and sometimes even the storage onto a single chip
Standoffs: Used to raise and attach your motherboard to the case
UEFI: Unified Extensible Firmware Interface
