CPU cores are used only when necessary for task acceleration. Enabling all cores allows faster program execution and better resource usage
CPU names consist of six segments: company name, brand, generation, model, and letter. Intel offers five main brands: Core, Xeon, Pentium, Celeron, and Atom. Brand modifiers categorize CPUs into i3, i5, i7, and i9 tiers. Generation indicates CPU's position in hierarchy, with newer generations offering improvements
System Information panel shows CPU cores and threads in Processor section. Task Manager's Performance tab displays cores and logical processors. Windows PowerShell uses WMIC commands to find core and thread counts. Command Prompt and Windows Terminal can use WMIC commands. Device Manager shows threads but not core counts
Hertz (Hz) is a shorthand for frequency, measuring occurrences per second. Frequency consists of count of occurrences and duration. SI prefixes like kilo (k) and mega (M) indicate very large numbers
Kernel is the part of domain mapped to zero vector of co-domain. Kernel is always a linear subspace of domain. Two elements have same image if their difference lies in kernel. Kernel is orthogonal complement to row space of matrix
Earth's internal structure excludes atmosphere and hydrosphere. Structure defined by mechanical properties or chemical composition. Earth's mass is about 6×10²⁴ kg, average density 5.515 g/cm³
