Lecture -5: Computer Hardware (Overview and CPUs)
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
The Memory/Storage Hierarchy and Virtual Memory
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
COMPUTER MEMORY - University of Babylon
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)
What is secondary memory?
- The secondary memory like magnetic disks and optical diskshas large storage capacities and store the data and instructions permanently, but are slow memory devices. The memories are organized in the computer in a manner to achieve high levels of performance at the minimum cost.
What are the different types of prospective memory tasks?
- Types of prospective memory tasks in a time-based prospective memory task, you plan to do an action at a certain time, such as remembering to call a friend in 10 minutes. 2. in an event-based task, you plan to complete an action when you see a specific cue or event, for example, remembering to give your friend a message when you see her.
What is a sensory memory register?
- The sensory register is a memory system that works for a very brief pe-riod of time that stores a record of information received by receptor cells until the information is selected for further processing or discarded. A. The sensory memory register is specific to individual senses: iconic memory for visual information
Do siblings have different memories?
- For example, siblings often have different memories of the same incident in their childhoods. Another assignment would be to have students write a paper in the form of a newspaper column on the role of memory in eyewitness testi-mony or repressed-memory cases.
