RAID: Redundant Array of Inexpensive Disks

- The term RAID was coined in 1987 as an acronym for Redundant Array of Inexpensive Disks; a computer storage technology that was first described by researchers David Patterson, Garth Gibson and Randy Katz at the University of California, Berkley. The concept proposed that an increase in I/O performance and storage reliability could be obtained by arranging several low-cost disk drives into arrays. Several different schemes of organizing the data across the array emerged and were described by the word RAID followed by a single number....   [tags: Computer Science]

With the explosive rise of digital media, computing devices and digital networks have allowed the ability for digital media to be distributed at a highly flexible and cost-efficient way. This has led to a change on how the media is being consumed, with more and more sales dropping for DVD’s and CD’s causing problems for many retailers but on the other hand digital media is rising in contrast.

How Does Photosynthesis Affect The Rate Of Photosynthesis?

- Photosynthesis is the primary activity of green leaves from which glucose is produced by inorganic materials – carbon dioxide and water – with light as the source of energy (Sheppard 1932). It is known that glucose is used by plants to develop and grow. Therefore, with a higher rate of photosynthesis, a higher amount of plant growth would be supplemented (Evans 2013). It is innocuously assumed that by speeding up the rate in which plants grow, a higher yield of crops can be collected within one harvesting season (Reynolds et al....   [tags: Carbon dioxide, Light, Leaf, Photosynthesis]

How Does The Amount Of Direct Light Effect The Cellular Process Of Photosynthesis?

- Problem/Purpose of Lab How does the amount of direct light effect the cellular process of photosynthesis. Photosynthesis is the conversion of light energy to chemical energy stored in sugars or other organic compounds. There are two main processes of photosynthesis; the light reactions and the calvin cycle. The light reactions occur in thylakoid membranes of the chloroplast. First a photon of light strikes a pigment molecule of photosystem II, exciting one of its electrons. While the electron falls back to ground state, a nearby pigment molecule is raised to its excited level....   [tags: Photosynthesis, Adenosine triphosphate]

- Introduction: What is photosynthesis, photosynthesis is the process where light energy is converted to chemical energy and storing it in chemical bond of sugar all these reactions take place in structures called chloroplasts. During the process of photosynthesis carbon dioxide, water, and light is consumed to produce glucose and oxygen. Thus bringing us to cellular respiration this is where plants consumes glucose and oxygen and produces carbon dioxide, water, and ATP energy molecules. To capture light energy for photosynthesis, chloroplasts absorb all light in the violet/blue and orange/red wavelengths....   [tags: Photosynthesis, Oxygen, Carbon dioxide]

Photosynthesis And The Light Reactions

- Introduction Photosynthesis is the way green plants use light to convert water and carbon dioxide into glucose (Photosynthesis, 2005). Oxygen is given off during this process (Photosynthesis, 2005). The formula for the photosynthesis reaction is stated below. 6 H20 (water) + 6 CO2 (carbon dioxide) (sunlight) C6H12O6 (glucose) + 6 O2 (oxygen) Photosynthesis can be squandered down to two parts: the light reactions and the dark reactions. The light reactions, the first stage of photosynthesis, takes place in the thylakoid membrane of the chloroplast and convert a photon (light energy) into chemical energy by exciting an electron into a higher orbital....   [tags: Photosynthesis, Carbon dioxide, Oxygen, Thylakoid]

The Effect Of Photosynthesis On The World 's Largest Solar Battery ( Rajni Godvinjee )

- Photosynthesis is a process in which autotrophs use the reactants carbon dioxide, water, and light energy to produce glucose and a byproduct of oxygen. It should also be pointed out that autotrophs are organisms that produce their own food by means of photosynthesis, such as plants and certain types of bacteria. Plants breath out the oxygen through their stomata, and could care about the oxygen as much as we care about breathing out carbon dioxide. Due to the byproduct of oxygen that is released from this process, it is essential to all life on earth, in an ever continuing cycle....   [tags: Carbon dioxide, Acid, PH, Photosynthesis]
