Virtual RAM - ✔✔- Space on a hard drive allocated by the OS that pretends to be
memory
- Page file (windows) or swap space (Mac, Linux)
Motherboard - ✔✔Printed circuit board that contains computer components and
provides connectors
ATX motherboard - ✔✔A full-size motherboard
Mini-ATX motherboard - ✔✔A motherboard that is smaller than ATX with similar
features
Micro-ATX motherboard - ✔✔A motherboard that is smaller than a mini-ATX, less
features and abilities
Mini-ITX motherboard - ✔✔A motherboard designed as replacement for ATX, smaller
and less abilities due to size, Information Technology eXtended
Expansion slots - ✔✔Slots that allow you to add extra computer components, think
PCIe
- Older, but also PCI
- M.2 slots (for SSD and Wi-Fi cards)
,CPU - ✔✔The primary component of a computer responsible for executing
instructions, performing calculations, and managing data processing tasks
ALU (Arithmetic Logic Unit) - ✔✔The part of the CPU that performs arithmetic
operations (add, subtract, etc.) and logical operations (and, or, not) on data
CU (Control Unit) - ✔✔The part of the CPU that manages and coordinates the
execution of instructions, controls data flow between different parts of the CPU and
memory, and oversees overall operations of computer's components
Register - ✔✔Small, high-speed storage units within the CPU that temporarily hold
data and instructions that the CPU is processing, enhancing data access speed and
overall efficiency
Pipelining - ✔✔- A technique used in CPU design to increase instruction throughput
by breaking down the instruction execution process into stages and allowing multiple
instructions to be processed simultaneously at different stages of the pipeline
- This enhances the overall speed of instruction execution
RAM (Random Access Memory) - ✔✔A computer component used to load
applications and files into a non-persistent and fast storage area, holds OS system code
L1 cache - ✔✔- Smallest and fastest cache
- Integrated into CPU core
L2 cache - ✔✔- Larger but slower than L1
- Resides outside of CPU core
, L3 cache - ✔✔- Larger but slower than L2
- Shared amongst all CPU cores
Memory slots - ✔✔Slots where you insert RAM sticks, DIMM slots (DDR3, DDR4,
DDR5), SODIMM slots (smaller for laptops)
Cache - ✔✔High-speed storage area that temporarily holds frequently accessed data
or instructions
Northbridge Chip - ✔✔A chip that manages fast connections between CPU, RAM,
graphics card
Southbridge Chip - ✔✔A chip that manages slow connections between hard drives,
USB ports, audio devices, network interfaces
HDD - ✔✔A storage device that stores data on metal or glass platter coated with
magnetic substance, cheaper for mass storage, slow
SSD - ✔✔A storage device that uses flash memory technology to implement
persistent mass storage, more expensive but fast
- NVMe
NAS - ✔✔A centralized storage system with sharing capabilities and remote access
RAID 0 - ✔✔- A RAID technique in which data is striped or alternated between disks
- Great for speed
- No data redundancy
