secondary memory. Data are transferred between different components of a computer system using physical wires called bus. For example bus is used for data
retrieval from a secondary memory component. For example complex span tasks (e.g.
A hard disk can store 2 TB to 5 TB data. 2. The primary memory comprises of RAM and ROM. 3. The secondary memory is also known as auxiliary storage. 4

memory is primarily RAM (Random Access Memory) Secondary memory is much slower and used for permanent non-volatile storage Secondary memory will usually be either a Solid State Drive (SSD) or a Hard Drive (sometimes abbreviated HDD) Smartphones have a similar divide between primary and secondary memory and include
Local secondary storage: disk drives Solid-State Disk (SSD): Flash memory (nonvolatile) Latency: 0 1 ms (~ 300k cycles) Capacity: 128 GB –2 TB Hard Disk: Spinning magnetic platters moving heads Latency: 10 ms (~ 30M cycles) Capacity: 1 –10 TB Cache / RAM Latency clock = 3·10-10sec
The secondary memory which is not as fast is used to store information permanently and is placed farthest from the processor With respect to CPU the memory is organized as follows: Registers are placed inside the CPU (small capacity high cost very high speed) Cache memory is placed next in the hierarchy (inside and outside the CPU)
