1. Verb‑Noun Command Structure

PowerShell uses a Verb‑Noun pattern to make commands predictable and readable.

Get-Process Set-Item Invoke-WebRequest

2. Pipeline Concept

PowerShell pipelines pass objects, not text.

Get-Service | Where-Object {$_.Status -eq "Running"}

PowerShell evaluates expressions directly:

PS> (5 + 3) * 2 16

More examples:

# Area of a circle PS> $r = 4 PS> [math]::PI * ($r * $r) 50.265482... # Pythagorean theorem PS> [math]::Sqrt((3*3) + (4*4)) 5

PowerShell outputs structured objects, not plain text.

PS> Get-Date | Get-Member
