What is communication net work?
A communication network is a collection of communication devices. They may be connected wirelessly or by wire. Examples include - A Ham Radio Net, A military radio net, or a family radio net, Cellular Telephones, Telephones, etc.
How did people communicate in 1980s?
Letters, telegrams, phones, a limited amount of e-mail, bulletin boards, radio, television and lots of other methods of communication were available in the 1980s.
A project on communication facilities in disaster management now please help?
Communication is a major bottleneck in case of any major disaster particularly when the traditional network system already in force brake down. In order to strengthen communications, it has been decided that police network (POLNET) will also be used for disaster management. For this purpose POLNET communication facility will be extended to District Magistrates, Sub Divisional Magistrates as well as the Control Rooms.For emergency communication, mobile satellite based units which can be transported to the site of the disaster are being procured. A group was constituted to draw a comprehensive communication plan for disaster management and the report has since been received. This provides for a dedicated communication system for disaster management with built in redundancies.Amateur radio is a community of people that use radio transmitters and receivers to communicate with other Amateur radio operators. If you were to ask a dozen different amateurs what ham radio meant to them chances are you would get 12 different answers. Amateur radio operators are often called ham radio operators or simply "hams" and frequently the public is more familiar with this term than with the legal term Radio Amateur. The source of this nickname is for all practical purposes lost from the beginning.Amateur (HAM) Radio is truly a hobby but often one that makes a difference especially in emergency or disaster situations. It is an activity of Self Learning, Inter-Communication & Technical Investigation carried on between Amateur Radio Operators. Amateurs talk to local friends over the radio waves using a hand-held transceiver, communicating digitally with packet radio to exchange personal messages or vital information in an emergency, talking to other hams anywhere in the world, or engaging in contests with other Radio Amateurs over the airwaves there is something for everyone.There are over Lakh people all over the world who pursue this activity in their free timeWhat Hams do with amateur radioQRP - Communicating with "very low power" is a challenge that many hams enjoy. QRP is usually practiced on the HF bandsHF radio - Hams can talk to other hams in literally any part of the globe using HF radiosVHF (2 meters) or UHF (70 cm.) transceivers hams enjoy extremely reliable communications within their local community. You can extend your VHF range up to 50 miles or more by transmitting through a local repeater.DXing. DX means distance communication and with the right equipment worldwide communication on the HF bands (10 through 160 meters) is a regular possibility.Emergency and other volunteer services - Floods, landslides, earthquakes, Cyclones, Accidents (Rail / Road / Air). when ever `normal' communications go out, hams are ready to use their radios to provide emergency communication services to their communitiesTechnical experimenting. Hams come from all walks of life ranging from technicians to engineers, teachers to scientists, and students to retirees. For many of them the attraction to the hobby is to build their own equipment whether it is just a simple antenna, something as complex as a transmitter, or an interface between their radio and a computer.Contesting. Contesting is often called the "sport" of ham radio. Almost every all the time there is some form of amateur radio contest. Hams get on the air and compete to see who can make the most contacts in a limited period of time.Talk to an astronaut. Yes, it is really possible. Space stations do have ham radio equipment and licensed ham astronauts take the time to make contacts with amateurs on earth. Hams also have satellites where you can bounce a signal to communicate with other hams on earth.Use digital communication. Connect a computer to your radio and install some software and you can be communicating digitally over the air. Some of these digital modes can be more effective in marginal transmission conditions and some even sport error free transmission.Internet communication. Using some of the latest technologies hams can supplement a modest station with Internet connections. Using features such as URL or IRLP on a local repeater a ham in Toronto can talk to one in Vancouver or even Australia using a simple hand-held transceiverAmateur television - It's just like real television because it is real television.Slow Scan TV - Send pictures around the world for little or no cost.Contests - You can put your radio operating skills up against other hams and teams of hams.Satellite communications - Hams operate using their own satellites for world wide communication using Walkie-Talkies.... They are easy to use too.Ham RadioHam Radio is also know as Amateur radio.It is a community of people that use radio transmitters and receivers to communicate with other Amateur radio operators.

This provides for a dedicated communication system for disaster management with built in redundancies.Besides the satellite, communication and education can play a proactive role in mitigation through awareness about the types of disaster and as to how prevention measures can be taken up.There is also a Satellite based communication system called the Cyclone Warning Dissemination Systems (CWDS) for transmission of warnings. There are 250 such cyclone-warning sets installed in the cylone prone areas of east and west coast. The general public, the coastal residents and fishermen, are also warned through the Government mechinery and broadcast of warnings through AIR and Television.What agencies need to be involved ?

The data processing and computers are providing a useful tool in decision making in disaster.When the disaster strikes, power goes out, all modes of communication (Telephone etc.) becomes inoperable, lifts stop functioning, when drinking water becomes contaminated, when normal modes of transportation suddenly becomes impossible, when casualties start coming in groups that is not the time for planning but that is the time of acting.Communication facilities for disaster management system is most important act as it convey at the right time communication in disaster, it may handle disaster and helping to decrease it.Two type of information needs in disaster management Pre disaster information: Question arise that how to get pre disaster information? It is getting from the research and analysis department of the geography in the country.Post disaster information: After the disaster, our first job is to find out where and where it was occurs. What is the next step to help people?Now a days Satellite communication play a major role in disaster management communication. Communication facilities can be set up for rescue and relief operation purposes. That type of early warning system developed at the different area's by itself.Here are the disaster communication facilities: DCWDS Digital Cyclone Warning Dissemination System set at Delhi and other coast area. It is for the pre disaster information.The WLL - VSAT system is in terms of handsets which can be easily taken inside of the affected areas and sends information by direct audio communication.The MSS Type C reporting terminal developed for the sending short messages directly through satellite in remote area.AES-SNG is a system which can send video pictures of the affected area for online review from the control center.Tele medicine: It is one more step for the disaster management communication. In this system, on line help can be provided from the hospital and super specialty doctors. Only connect up link to laptop or PC and get the online information about cure."Pocket Guide on First Aid"The First Aid pocket guide should contain aid that needs to be given for fractures, poisoning, cuts and burns, heat and cold wave and other threats that are prevalent in that area. The content shared in the guide should be supported with adequate pictures so as to give a clear and elaborate understanding about the topic. Choose awareness campaign strategy for either senior citizens or illiterate people and prepare a brief write-up.You need to first arrange it, first the cover page should have a red cross, then it should have an index ( it is necessary) the cover page can be of light blue colour with a red crosses box picture.You can use the red red cross pictures that we have posted in the end of this article.It should include "DRABCD" : DangerResponseAirwayBreathingCompressions/CirculationDephibrilationBelow is the list of supplies you should have in your First Aid : Plastic bandagesTranspore tapeAlcohol prepsAdhesive bandagesMicropore tapeGauzeExtra large plasticbandagesIodine prep padsFingertip bandagesSterile padsAntiseptic towelettesKnuckle bandagesAntiseptic ointmentAmmonia inhalantSponge packsInstant ice packsSterile eye washElastic bandagesEye padsSafety pinsFirst aid creamBandage scissorsTweezersButterfly bandagesWater tight utilitybox for contentsBurn gel to treat burnsBurn bandagesAdhesive spotsExtra large stripsSurgical tapeSpongesPain relieverWhat is the aim of First Aid ?The key aims of first aid can be summarised in three key pointsPreserve life is the overriding aim of all medical care, including first aid, is to save livesPrevent further harm also sometimes called preventing the condition worsening, this covers both external factors, such as moving a patient away from a cause of harm, and applying first aid techniques to prevent worsening of the condition, such as applying pressure to stop a bleed becoming dangerous.Promote recovery - first aid also involves trying to start the recovery process from the illness or injury, and in some cases might involve completing a treatment, such as in the case of applying a plaster to a small wound.First aid training often also incorporates the prevention of initial injury and responder safety, as well as the treatment phases.When First Aid is Required ?Altitude sickness, which can begin in susceptible people at altitudes as low as 5,000 feet, can cause potentially fatal swelling of the brain or lungs.Anaphylaxis, a life-threatening condition in which the airway can become constricted and the patient may go into shock. The reaction can be caused by a systemic allergic reaction to allergens such as insect bites or peanuts. Anaphylaxis is initially treated with injection of epinephrine.Battlefield First aid - This protocol refers to treating shrapnel, gunshot wounds, burns, bone fractures, etc. as seen either in the 'traditional' battlefield setting or in an area subject to damage by large scale weaponry, such as a bomb blast or other terrorist activity.Bone fracture, a break in a bone initially treated by stabilizing the fracture with a splint.Burns, which can result in damage to tissues and loss of body fluids through the burn site.Choking, blockage of the airway which can quickly result in death due to lack of oxygen if the patient's trachea is not cleared, for example by the Heimlich Maneuver.Childbirth.Cramps in muscles due to lactic acid build up caused either by inadequate oxygenation of muscle or lack of water or salt.Joint dislocation.Diving disorders resulting from too much pressure.Near drowning or asphyxiation.Gastrointestinal bleeding.Gender-specific conditions, such as dysmenorrhea and testicular torsion.Heart attack, or inadequate blood flow to the blood vessels supplying the heart muscle.Heat stroke, also known as sunstroke or hyperthermia, which tends to occur during heavyexercise in high humidity, or with inadequate water, though it may occur spontaneously in some chronically ill persons. Sunstroke, especially when the victim has been unconscious, often causes major damage to body systems such as brain, kidney, liver, gastric tract. Unconsciousness for more than two hours usually leads to permanent disability. Emergency treatment involves rapid cooling of the patient.Heat syncope, another stage in the same process as heat stroke, occurs under similar conditions as heat stroke and is not distinguished from the latter by some authorities.Heavy bleeding, treated by applying pressure (manually and later with a pressure bandage) to the wound site and elevating the limb if possible.Hyperglycemia, or diabetic coma.Hypoglycemia, or insulin shock.Hypothermia, or Exposure, occurs when a person's core body temperature falls below 33.7°C (92.6°F). First aid for a mildly hypothermic patient includes rewarming, but rewarming a severely hypothermic person could result in a fatal arrhythmia, an irregular heart rhythm.Insect and animal bites and stings.Muscle strain.Poisoning, which can occur by injection, inhalation, absorption, or ingestion.Seizures, or a malfunction in the electrical activity in the brain. Three types of seizures include agrand mal (which usually features convulsions as well as temporary respiratory abnormalities, change in skin complexion, etc) and petit mal (which usually features twitching, rapid blinking, and/or fidgeting as well as altered consciousness and temporary respiratory abnormalities).Sprain, a temporary dislocation of a joint that immediately reduces automatically but may result in ligament damage.Stroke, a temporary loss of blood supply to the brain.Sucking chest wound, a life threatening hole in the chest which can cause the chest cavity to fill with air and prevent the lung from filling, treated by covering with an occlusive dressing to let air out but not in.Toothache, which can result in severe pain and loss of the tooth but is rarely life threatening, unless over time the infection spreads into the bone of the jaw and starts osteomyelitis.

It was originally considered to mean Spiced Ham. Since Spam contains less that 1% ham Hormel later suggested it might mean Shoulder of Pork and ham. They now argue that it isn't really an acronym at all, but simply a name in itself.
What is spam processed meat?
Funny how no one ever comes up with a satisfactory answer. I think, my opinion, that it means spiced ham, here's why. A friend of my mother had a recipe she found for a nice spiced ham, it called for soaking a polish canned ham in lemon juice overnight then baking it with cloves and pineapple. It tasted exactly like Spam. I like spam.
How did spam get its name?
The Legend of Spam: Back in 1937, the Hormel Foods company invented a canned, spiced ham that became super popular back during WWII due to the scarcity of fresh meats. In the 1960s the British TV show "Monty Python's Flying Circus" had a regular skit about a restaurant that served spam with everything, spam burgers, spam omelets, spam mashed potatoes, spam apple pie, spam spam, etc. In the skit there was a table of customers that would sing "Spam, spam, spam, spam, spam, beautiful spam, wonderful spam!" until someone would make them shut up. At some point the term made the cultural jump to describe junk e-mail that repeats itself everywhere, and because of its repetitive, annoying nature. Additional Information: Introduced in 1937, the original name was Hormel Spiced Ham. Later the name of SPAM was derived from SP (from spiced) and AM (from ham). In humorous circles it was called Something Posing As Meat - or Spare Parts Animal Meat
Where does the word Spam come from?
I think it's a contraction of "spiced ham" or "spiced pork and ham". This was is a tinned meat product made famous during WW2 by the Americans in Europe. Food was rationed and it was welcomed at the time. When war ended more food became available and Spam got a reputation as being for poor people. Hence the term for unwanted messages and adverts. Spam was popular in the US as well. During rationing in the US, you were only allowed so much meat in a week. You were allowed far more canned goods in your rations. Spam counted as a canned good but was meat. So you could still get meat if you liked Spam. The source is my mother who was a teenager in WW II. I've heard the story other places so it seems reliable. I think its reputation was low because nobody really understood what was in it but that's more conjecture.
