Explanation

• Memory (RAM): Temporary, volatile, fast access
• Storage (HDD/SSD): Permanent, non-volatile, slower than RAM
• Example Memory: RAM in computers (4GB, 8GB, 16GB)
• Example Storage: Hard disk, SSD (256GB, 512GB, 1TB)
• Purpose: Memory = active tasks, Storage = long-term data

Explanation

• 1 byte = 8 bits; therefore, 4 bytes = 4 × 8 = 32 bits.
• A bit is the smallest unit of digital data.
• It can represent 0 or 1.

Additional information:

• 1 byte = 8 bits
• 2 bytes = 16 bits
• 4 bytes = 32 bits
• 8 bytes = 64 bits
• 1 KB = 1,024 bytes
• 1 MB = 1,024 KB

Explanation

• 1 Terabyte (TB) = 1000 Gigabytes (GB)

Additional information:

• 1 Gigabyte (GB) = 1000 Megabytes (MB)
• 1 Megabyte (MB) = 1000 Kilobytes (KB)

Explanation

• The correct sequence of data storage units from smallest to largest is Byte (B) → Kilobyte (KB) → Megabyte (MB) → Gigabyte (GB).
• A Byte is a basic unit of digital data and typically contains 8 bits.
• 1 KB = 1,024 bytes in the commonly used binary convention.
• 1 MB = 1,024 KB and 1 GB = 1,024 MB under the same convention.

Explanation

• Logic gates are the fundamental building blocks of digital systems.
• The AND, OR, and NOT gates are the most fundamental logic gates.
• The NAND and NOR gates are called universal gates because they can be combined to produce OR, AND, and NOT gates.
