Catherine Grace L. Tomas BSIT-4B TRANSMISSION MEDIA The means through which data is transformed from one place to another is called transmission or communication media. There are two categories of transmission media used in computer communications. Infrared Infrared transmission is usually limited to a small area‚ e.g. one room‚ with the transmitter pointed towards the receiver. The hardware is inexpensive and does not require an antenna.

Why Psychology is Important Psychology is the study of the human mind and any of its functions. It also includes the behavior resulting from any changes in our environment. Psychology is very important to mankind in that it is important in understanding the world we live in. Psychology helps us and allows us to better understand the emotional and behavioral effects of our surroundings. According to Taylor (1988)‚ many prominent researchers believe a healthy mental outlook on the world and what

effects of each. The two branches of the Autonomic Nervous System are the sympathetic division and the parasympathetic division. The main process of the sympathetic division is to stimulate the fight-or-flight response in the body‚ which means it is in charge of stimulates actions. In the sympathetic system‚ epinephrine and norepinephrine are the main neurotransmitter. In the sympathetic system‚ there are two neurons involved in transmission and they are the pre-ganglion and post-ganglion. The

HIV transmission HIV is present to variable degrees in the blood and genital secretions of almost all individuals infected with HIV.The spread of HIV can occur when these secretions come in contact with tissues such as those lining the vagina‚ anal area‚ mouth‚ or eyes (the mucus membranes)‚ or with a break in the skin‚ such as from a cut or puncture by a needle. The most common ways in which HIV is spreading throughout the world include sexual contact‚ sharing needles‚ and by transmission from infected

Organizational Theory: Determinants of Structure -------------------------------------------------------------------------------- The objective here is to understand why organizations have the structure that they do. By "structure" I mean things like degree and type of horizontal differentiation‚ vertical differentiation‚ mechanisms of coordination and control‚ formalization‚ and centralization of power.

Why is an understanding of evolutionary and population processes important for species conservation? Abstract Evolution is it a theory of previous life becoming more like present life over time through means such as "natural selection" With an endless diversity of life‚ and variation as a result of the interactions of organisms with their environments. Fundamental to the process of understanding how evolution works is to look at a combination of many mechanisms such as genetic variation‚

Describe the neuroanatomy of and neural processes related to learning based on current literature. Through research and laboratory studies‚ we have a better understanding of how learning can truly physically change the structure of the brain and its functional organization. With these advancements in cognitive neurosciences‚ educators and psychologists can enhance and form learning techniques to fit multiple settings and learning styles. However‚ as we grow into adulthood our “perception”

Transmission media lie below the physical layer. We can evaluate transmission media by throughput‚ propagation speed‚ and propagation time. * A guided medium provides a physical conduit from one device to another. Twisted-pair cable‚ coaxial cable‚ and optical fiber are the most popular types of guided media. Twisted-pair cable consists of two insulated copper wires twisted together. Twisting allows each wire to have approximately the same noise environment. Twisted-pair cable is used in

Fourthly‚ they have psychomotor disturbances whereby they can remain in an unusual position for hours (this is known as ‘catatonia’). Lastly‚ they may have lack motivation and interest in life.
