Memory and disk storage are two different types of storage used in computing systems.
Memory, also known as RAM (Random Access Memory), is a type of volatile storage that is used by the computer to store data and instructions that are currently being used by the CPU. Memory is much faster than disk storage, but it is also more expensive and has limited capacity. When the computer is turned off, the data stored in memory is lost.
Disk storage, on the other hand, is a type of non-volatile storage that is used to store data and files for long-term use. Disk storage is slower than memory, but it has much larger capacity and is more cost-effective. There are two main types of disk storage: hard disk drives (HDD) and solid-state drives (SSD). HDDs use spinning disks to store data, while SSDs use flash memory chips. SSDs are faster and more reliable than HDDs, but they are also more expensive.
Overall, memory is used for short-term storage of data that is currently being used by the computer, while disk storage is used for long-term storage of files and data. Both types of storage are essential for the proper functioning of a computer system.

Memory (RAM)
- Type of Technology: Semiconductor memory
- Function: Stores data and instructions that are actively being processed by the computer.
- Characteristics:
- Extremely fast (access time in nanoseconds)
- Volatile (data is lost when power is turned off)
- Random access (data can be accessed directly at any location)
Disk Storage
1. Hard Disk Drives (HDD)
- Type of Technology: Magnetic storage
- Function: Stores data on spinning magnetic disks.
- Characteristics:
- Large capacity (up to several terabytes)
- Slower access time (milliseconds) than RAM
- Non-volatile (data is retained even when power is off)
- Sequential access (data must be accessed in order)
2. Solid State Drives (SSD)
- Type of Technology: Flash memory
- Function: Stores data on flash memory chips.
- Characteristics:
- Much faster access time than HDDs (microseconds)
- Lower capacity than HDDs
- Non-volatile
- Random access
3. Optical Disc Drives (ODD)
- Type of Technology: Optical storage
- Function: Stores data on optical discs (e.g., DVDs, Blu-rays).
- Characteristics:
- Large capacity (up to several gigabytes)
- Read-only or read/write
- Slow access time
- Portable
