📌 Topic 2: Number Systems (Системы счисления)

This topic focuses on converting between bits, bytes, kilobytes, and megabytes. 1 byte = 8 bits 1 Kilobyte (KB) = 1024 bytes 1 Megabyte (MB) = 1024 KB Example 1:

To convert bits to bytes, divide by 8 ( ). Options B and C are mathematically incorrect. Q2: 🟢 B) 10. . Options A and C do not match the calculation.

1×23+1×22+0×21+1×201 cross 2 cubed plus 1 cross 2 squared plus 0 cross 2 to the first power plus 1 cross 2 to the 0 power =8+4+0+1=13equals 8 plus 4 plus 0 plus 1 equals 13 💡 131013 sub 10
