Memory Fundamentals processes relating to memory 1. Encoding – the process by which information is initially recorded in the memory 2. Storage – the maintenance of material saved in the memory 3. Retrieval –when the material in the memory storage is located‚ brought into awareness and used. Three kinds of memory storage systems (Memory Storehouses) 1. Sensory Memory – the initial‚ momentary storage of information‚ lasting only an instant 2. Short-term memory – which

our MEMORY. A flow of events must occur before we can say “I remember”. Memory is “an active system that receives‚ stores‚ organizes‚ alters and recovers information” (Lieberman‚ 2004). In general‚ memory acts like a computer. Incoming information will be encoded‚ it is like typing data into a computer. Next‚ stored the information that we typed into the system. Finally‚ memories must be retrieved in order to be useful. According to Parente and Stapleton (1993)‚ they stated that “memory is a

Data stored in backing storage is permanent so it is NOT lost when the computer is turned off. It is always slower to access data from backing storage than from internal memory.

Types of Storage Devices Physical components or materials on which data is stored are called storage media. Hardware components that read/write to storage media are called storage devices. Two main categories of storage technology used today are magnetic storage and optical storage. Primary magnetic storage o Diskettes o Hard disks (both fixed and removable) o High capacity floppy disks o Disk cartridges o Magnetic tape Primary optical storage o Compact Disk Read Only Memory (CD ROM)

MEMORY- THE INTERFERENCE THEORY FIZZA LAKHANI INSTITUTE OF PROFESSIONAL PSYCHOLOGY‚ BAHRIA UNIVERSITY‚ KARACHI. BS-4 Abstract The aim of this study was to observe the interference theory on different age groups. It was assumed that the recalling of 1st list will be affected by interference of another list‚ teenagers will recall more nonsense syllables than adults and also participants who performed experiments with distractions will have less correct responses than those who conducted without

Question 1 a) The difference between a subject directory and a search engine is the way in which the information about a website is gathered. Search engine is a program that finds Web sites‚ Web pages‚ images‚ videos‚ news‚ maps‚ and other information related to specific topic. A search engine is helpful in locating information for which we do not know an exact Web address or are not seeking a particular Web site. A subject directory classifies Web pages in an organized set of categories

STORAGE DEVICE Definition A storage device can be defined as any piece of hardware whose main function is to store data and information The hardware that writes data to or reads data from a storage medium is called a storage device. Types of Computer Storage Devices Computer storage devices can be classified into o Primary storage o Secondary storage o Tertiary storage Primary Computer Storage Devices Primary storage refers to the computer’s memory(RAM) RAM (Random Access Memory)

Memory and the Different Types of Memory Abstract This paper explains the differences between the each type of memory. Research will also show the roles of each memory system and how they pertain to memory. This paper will concentrate on each area of memory and will explain the problems of forgetting. Memory and the Different Types of Memory Memory can be defined as a “processes that are used to acquire‚ store‚ retain and later retrieve information. There are three major processes involved

The need for more storage is growing. The amount of data produced is doubling in every two years. (in 2010 – 1.8 zettabytes) The cost of creating‚ managing and storing the data is decreasing‚ but can the optical storage expand further? The current Blu-ray lasers emit light in the blue part of the electromagnetic spectrum (about 420 nanometer wavelength). There are ongoing researches using UV light‚ that would probably have to be 200 nm and would provide storage capacities of over 100 GB in a single
