Study Notes
Learning Outcomes
- Students should be able to outline different memory types and characteristics of secondary storage devices.
Memory Types
- Read Only Memory (ROM): A type of memory that is non-volatile, retaining information even when powered off.
- Random Access Memory (RAM): A volatile memory type that loses data when power is switched off.
Storage Overview
- Storage Medium: The physical material on which data is stored.
- Storage Device: Hardware used to read/write data stored on storage mediums.
-
Secondary Storage Characteristics:
- Offers large capacity.
- Non-volatile, retaining data without power.
- Generally more cost-effective compared to other forms of storage.
- Slower access speeds compared to primary memory.
Storage Units
- Binary Digit (bit): The smallest unit of data, representing a state of either 0 or 1.
- Byte: A unit of storage comprising 8 bits, capable of storing one character (e.g., "A").
- Kilobyte (KB): Equals 1,024 bytes.
- Megabyte (MB): Equals 1,024 KB.
- Gigabyte (GB): Equals 1,024 MB.
Storage Speed Comparison
- Fastest Current Storage: Hard Disk Drive (HDD).
-
Slower Options:
- USB Flash Drive.
- CD/DVD Drive.
- Floppy Disk Drive.
- Tape Drive, which is the slowest.
Common Storage Capacities
