Short-term memory, also known as primary or active memory, is the capacity to store a small amount of information in the mind and keep it readily available for a short period of time.

reconstruction. Rebuilding a memory out of stored elements. encoding specificity. A process in which memories incorporate unique combinations of information when encoded.

Working memory is a relatively recent term, a refinement of an older concept – that of short-term memory. Short-term memory was called thus to distinguish it from “long-term memory” – your memory store. Working memory contains the information of which you are immediately aware.

Memories leave lasting traces in the brain. They put continuity to our lives and give us an identity. The nature of memory is based on intense interconnections between neurons.

Characteristic of Static RAM

• Long life.
• No need to refresh.
• Faster.
• Used as cache memory.
• Large size.
• Expensive.
• High power consumption.

Storage devices

• speed (how quickly data can be accessed)
• cost per storage unit (i.e. price per gigabyte or megabyte)
• durability (toughness)
• portability (how easy it is to move it from one computer to another)

10 Digital Data Storage Devices for Computers

• Hard Drive Disks.
• Floppy Disks.
• Tapes.
• Compact Discs (CDs)
• DVD and Blu-ray Discs.
• USB Flash Drives.
• Secure Digital Cards (SD Card)s.
• Solid-State Drives (SSDs)

Whereas memory refers to the location of short-term data, storage is the component of your computer that allows you to store and access data on a long-term basis. Usually, storage comes in the form of a solid-state drive or a hard drive.

RAM

• Static RAM (SRAM)
• Dynamic RAM (DRAM)
• MROM (Masked ROM)
• PROM (Programmable Read Only Memory)
• EPROM (Erasable and Programmable Read Only Memory)
• EEPROM (Electrically Erasable and Programmable Read Only Memory)
• Advantages.
• Disadvantages.

Both RAM and hard drive memory are referred to as memory, which often causes confusion. RAM stands for Random Access Memory. When your computer is turned on, it loads data into RAM. Programs that are currently running, and open files, are stored in RAM; anything you are using is running in RAM somewhere.
