GASEOUS DISCHARGE LAMPS: A gaseous discharge lamp is essentially a glass or quartz envelop containing two electrodes and a small quantity of gas or vapour at a low pressure. In these lamps light is obtained by applying an electric potential difference to a gas or vapour contained by the lamp under a suitable pressure. Due to application of electric potential difference gas gets ionised and an electric current flows; the tube is filled with a luminous discharge. The light spectrum

dictionary defines memory as the mental capacity or faculty of retaining and reviving facts‚ events‚ and impressions‚ or of recalling or recognizing previous experiences. However‚ the dictionary does not reveal the wondrous and downright horrifying things about memory. Memory is my ally‚ but a fickle one. I believe memory serves as a funnel to the past‚ except this funnel faces the opposite direction. My past moments are poured into the smaller end‚ causing most of my memories to be lost. Actually

SAN is called Storage Area Network also called Server area Network. A storage area network (SAN) is a high-speed special-purpose network (or subnetwork) that interconnects different kinds of data storage devices with associated data servers on behalf of a larger network of users. Typically‚ a storage area network is part of the overall network of computing resources for an enterprise. A storage area network is usually clustered in close proximity to other computing resources but may also extend

A. VOLATILE MEMORY Volatile memory‚ also known as volatile storage‚ is computer memory that requires power to maintain the stored information‚ unlike non-volatile memory which does not require a maintained power supply. It has been less popularly known as term Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge‚ the information eventually fades unless the capacitor

Computer Memory Basics Although memory is technically any form of electronic storage‚ it is used most often to identify fast‚ temporary forms of storage. If your computer’s CPU had to constantly access the hard drive to retrieve every piece of data it needs‚ it would operate very slowly. When the information is kept in memory‚ the CPU can access it much more quickly. Most forms of memory are intended to store data temporarily. As you can see in the diagram above‚ the CPU accesses memory according

False memories have been defined as "either remembering events that never happened‚ or remembering them quite differently from the way they happened (Park‚ 2012). This topic opens many doors for research and raises questions about the reliability and susceptibility of people’s memory. Memory is the mental faculty of retaining and recalling past experiences. A repressed memory is one that is retained in the subconscious mind‚ where one is not aware of it but where it can still affect both conscious

are many things to help this common problem. By studying what Ive learned about memory and learning‚ I will use this information to assess my own study habits and make them more effective. Encoding information in short-term memory is stored according to the way it sounds‚ the way it looks‚ or its meaning. Verbal information is encoded by sound‚ even if it is written rather than heard. Visual encoding in short-term memory is greater than encoding by sound. To help with studying‚ a student should look
