+### Binary Denary Conversion
+
+#### Convert to Binary
+
+- 9 = 00001001
+- 45 = 00101101
+- 171 = 10101011
+- 238 = 11101110
+
+#### Convert to Denary
+
+- 00010001 = 17
+- 00110101 = 53
+- 10011010 = 154
+- 10110111 = 183
+
+### Basic Linux Commands
+
+- **ls** (list)
+- **cd** (navigate directory)
+- **~** - home directory
+- **/** (root system directory)
+- **rmdir** (remove directory)

+- **cp** (copy)
+- **mv** (move)
+- **rm** (remove)
+- **pwd** (print working directory)
+
+#### **vi** (visual editor)
+
+- not hype, use for assessments only

+
+- hype, use everywhere outside of assessments
