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.

mosquitoes There are four types of human malaria: - Plasmodium falciparum - Plasmodium vivax - Plasmodium malariae - Plasmodium ovale Plasmodium falciparum and Plasmodium vivax are the most common. Plasmodium falciparum is the most deadly. METHOD OF TRANSMISSION - Through the bites of infected Anopheles mosquitoes - They breed in shallow collections of freshwater like puddles‚ rice fields‚ and hoof prints SIGNS & SYMPTOMS Symptoms appear 7–15 days after the infective mosquito bite : - Fever - Headache

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

TRANSMISSION LINES Introductory Lecture Engr. Duwi E. Iscala SoE/APC What are transmission lines? • Transmission lines are pieces of wire or cable used to carry telephone signals‚ computer data in LANs‚ TV signals in cable TV systems‚ and signals from a transmitter to an antenna‚ or vice versa. Transmission Line • Definition: – Any means of conveying signal or power from one point to another What are the different types of transmission lines? • Parallel-wire lines What are the

Running Head: SYNAPTIC TRANSMISSION Synaptic Transmission Grand Canyon University PCN 310 Synaptic Transmission They can proceed in several ways‚ both presynaptically and postsynaptically. They can influence how vesicles issue neurotransmitters‚ how neurotransmitters are cleaved/reuptake‚ they can hinder receptors‚ destroy receptors‚ and agonistically join to receptors which mimic the neurotransmitter. These are a few. Synapses are vital to the function of the nervous system. The most

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

Brochure More information from http://www.researchandmarkets.com/reports/604386/ Analyzing Microwave Power Transmission & Solar Power Satellite Systems Description: Microwave power transmission (MPT) involves the usage of microwaves to transmit power through outer space or the atmosphere without the need for wires. It is a sub-type of the more general wireless energy transfer methods‚ and is the most interesting because microwave devices offer the highest efficiency of conversion between DC-electricity
