A computer system consists of mainly four basic units; namely input unit‚ storage unit‚ central processing unit and output unit. Central Processing unit further includes Arithmetic logic unit and control unit‚ as shown in the figure:. A computer performs five major operations or functions irrespective of its size and make. These are • it accepts data or instructions as input‚ • it stores data and instruction • it processes data as per the instructions‚ • it controls all operations inside a computer

PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)

BEECH FOREST ECOSYSTEMS INTRODUCTION This essay will look at beech forest ecosystems‚ describing the main characteristics‚ along with pre-human and current distribution of beech forests. Vegetation structure and native fauna associated with the ecosystem will be looked at with examples of species given. Environmental effects such as altitude‚ latitude‚ rainfall and soil drainage‚ and how they can affect beech forests will be investigated. Anthropogenic effects will also be looked at‚ explaining

us? o Nature – genes‚ heredity o Nurture – everything else that is not genetic (experience‚ environment) - Both are equally important in shaping who we are. There is also an interaction between the two. STUDY NOTES ONLY II – The Nature Component A) Genes: - 46 chromosomes‚ 23 pairs. - Genes carry DNA‚ which consists of thousands of genes amongst other things. - Genes = Basic Unit of Heredity - Gene complexes are genes working together to produce a trait or disease. - 4 Nucleotides:

“Describe a theoretical approach whose influence on our understanding of perception has been particularly important‚ and explain your choice.” Recognition-by-components (RBC) theory (Biederman‚ 1987) has greatly influenced our understanding object perception and‚ more specifically‚ recognition. Recognition has been defined by Goldstein (2010) as how humans can categorise objects to give them meaning. RBC suggests that our recognition of objects is dependent on dividing the stimulus into a number

Colonisation and Succession in an Ecosystem 1. Ecosystem is a community of organisms which interact with their non-living environment and function as a unit. 2. Habitat is a natural environment where organisms live. Also provide shelter‚ food‚ living space‚ nesting sites and mates. 3. Species is a group of organisms that look alike and have similar characteristics‚ share the same roles in an ecosystem and are capable of interbreeding to produce fertile offspring. 4. Population is

Urban ecosystem and Ecopolis Lai Wei March 29‚ 2012 Introduction When people talk about the city‚ the first thing they thought is the building and the traffic. It’s hard to connect city to the ecological and the environment. But as the humanity is rapidly urbanizing‚ by 2010‚ more than 50% of the world population is expected to live in the city. (The World Bank‚ 2010) Cities can be tremendously efficient. It can easier to provide water and sanitation for a large number of people living

A food web is the entirety of interrelated food chains in any and every ecosystem. This delicate balance is the connection between predator and prey‚ consumer and producer‚ and autotroph and heterotrophs. Food web’s also allows you to follow the direction of the flow of energy as each organism consumes each of their indicated food sources. For example‚ the energy from the sun is taken in by producers‚ such as ‚ trees‚ grass and fruit. Then goes to an autotroph would be eaten by a second trophic
