15 NETIQUETTE RULES

• Before posting your question to a discussion board, check if anyone has asked it already and received a reply.  -->>> "Dahil maaring ma'Out of topic ikaw o sila kapag nag Post ka ng tanong na hindi pa nila alam kaya, kaya dapat alamin muna kung ito bay alam na nila o tinatanong nila nang sa ganun maging maayos ang usapan".
  
•  Stay on topic. Don't post irrelevant links, comments, thoughts or pictures -->>>  "kung ano man topic ang pinaguusapn, dapat yun lang i'avoid naten ang mag post ng ibang topic, magbigay ng ibang komento tungkol sa usapan, dahil hindi maganda yun maaaring hindi sila Makarelate".
  
• Don't type in ALL CAPS! If you do it will look like you are screaming. -->>> "Iwasan naten ang naka ALL CAPS dahil hindi magiging maganda ang deliver ng post mo, maaaring isipin ng reciever na ikay Galit o sumisigaw".
  
• Don't write anything that sounds angry or sarcastic even as a joke, because without hearing your tone of voice, your peers might not realize you're joking. -->>> "Iwasan natendin naten mgsulat o magpost na parang tayo ay galit kahit pa sabhin na biro lang yun, hanggathindi nila naririnig ang tema o tono ng boses sa pgsabi nun sa personal hindi padin nila maiisip na biro lang yun".
  
• Always remember to say"please" and "thank you" when soliciting help from your classmates. -->>> "Lagi naten tandaan na kapag hihingi tayo ng tulong sa kaibigan o kaklase naten lagi naten gamitin ang Salitang PLEASE and THANK YOU".
  
• Respect the opinion of your classmates. If you feel the need to disagree, do so respectfully and acknowledge the valid points in your classmate's argument. If you reply to a question from a classmate, make sure your answer is accurate! -->>> "Iwasan naten ang Pambabastos na salita, kapag may taong nagbigay opinyon na kaylangan mong tumutol, gawin naten yung karesperespeto  at maayos, para hindi sumama ang loob ng isang tao, at kung sasagot ka naman sa tanong ng isang kaklase dapat sumagot tayo ng tama at ayos".
  
• If you ask questions , many people respond. Summarize all answers and post that summary to benefit your whole class. -->>> "At kapag magtatanong tayo, madami syempre ang sasagot. Gawin paikliin ang lahat ng magiging sagot nila ng sa ganun maging mapakinabang o usefull iyon sa buong klase".
  
• Be brief. If you write a long dissertation in response to a simple question, it's unlikely that anyone will spend the time to read through it all. -->>> "kung sasagot tayo o mgrerespond ng napakahaba sa isang napakasimpleng tanong maaaring hindi magustuhan ng iba hindi sila magtitiyaga mgbasa ng mahabang sagot sa isang simpleng tanong".
  
• Don't badmouth others or call them stupid. You may disagree with their ideas but don't mock the person. -->>> "Pwede tayo di sumang ayon sa ideas ng iba dahil may kanya kanya tayong opinyon o ideya, pero hindi porket di-sang ayon e kailangan na naten sila pagsalitaan ng Tanga o anuman masasakit na salita iwasan naten yun".
  
• If you refer to something your classmate said earlier in the discussion, quote just a few key lines from their post so that others won't have to go back and figure out which post you're referring to. -->>> "Kung medon man tayong babanggitin sa iba tungkol sa sinabi ng classmate naten knina, paikliin nalang naten kunin naten kung ano yung mahahalagang lines na sinabi nya nangd sa ganun hindi balikan pa ng iba kung ano ba yung ibig mong banggitin".
  
• Before asking a question, check the class FAQs or search the Internet to see if the answer is obvious or easy to find. -->>> "Kung sakaling magtatanong tayo, siguraduhin muna naten kung yung bang itatanong naten ay madaling masagot search muna naten sa internet ng sa ganun madali nila maintindihan".
  
• Check the most recent comments before you reply to an older comment. -->>> "Bago tayo mgrespond o sumagot sa isang comment kaylangan muna naten alamin kung ano yung mga bagong comments bago sumagot sa mga lumang comments".
  
• Be forgiving. If your classmate makes a mistake, don't badger him or her for it. Just let it go. -->>> "Kung nakagawa man ng isang pagkakamali ang isa naten kaklase o kaibigan, wag natin sila awayin o yamutin, Hayaan nalang naten, maging Mpagpatawad tayo".
  
• Run a spelling and grammar check before posting anything to the discussion board. -->>> "Make sure naten na tama ang grammar at spelling ng ipopost naten".

*MODEM DIAL UP CONNECTION

Dial-up Internet access is a form of Internet access that uses the facilities of thepublic switched telephone network (PSTN) to establish a connection to an Internet service provider (ISP) by dialing a telephone number on a conventional telephone line. The user's computer or router uses an attached modem to encode and decode information into and from audio frequency signals, respectively. Despite the proliferation of high-speed Internet access (broadband), dial-up Internet access may be used where other forms are not available or the cost is too high, such as in some rural or remote areas.

Dial-up Internet has been around since the 1980s via public providers such asNSFNET-linked universities and was first offered commercially in July 1992 bySprint.^[1].

*MODEM

A modem (modulator-demodulator) is a network hardware device that modulatesone or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used with any means of transmitting analog signals, from light emitting diodes to radio. A common type of modem is one that turns the digital data of a computer into modulated electrical signal for transmission over telephone lines and demodulated by another modem at the receiver side to recover the digital data.

Modems are generally classified by the amount of data they can send in a givenunit of time, usually expressed in bits per second (symbol bit/s, sometimes abbreviated "bps"), or bytes per second(symbol B/s). Modems can also be classified by their symbol rate, measured in baud. The baud unit denotes symbols per second, or the number of times per second the modem sends a new signal. For example, the ITU V.21 standard usedaudio frequency shift keying with two possible frequencies, corresponding to two distinct symbols (or one bit per symbol), to carry 300 bits per second using 300 baud. By contrast, the original ITU V.22 standard, which could transmit and receive four distinct symbols (two bits per symbol), transmitted 1,200 bits by sending 600 symbols per second (600 baud) usingphase shift keying.

MODULATOR

An RF modulator (or radio frequency modulator) is an electronic device whose input is a baseband signal which is used to modulate a radio frequency source.^[1]

RF modulators are used to convert signals from devices such as media players,VCRs and game consoles to a format that can be handled by a device designed to receive a modulated RF input, such as  a radio or television receiver  

DEMODULATOR       
A demodulator is an electronic circuit (or computer program in a software-defined radio) that is used to recover the information content from the modulated carrier wave.  

*BROADBAND  
A high-capacity transmission technique using a wide range of frequencies, which enables a large number of messages to be communicated simultaneously.
In telecommunications, broadband is a wide bandwidth data transmission with an ability to simultaneously transport multiple signals and traffic types. The medium can be coaxial cable, optical fiber, radio or twisted pair.

CABLE
A thick rope of wire or nonmetallic fiber, typically used for construction, mooring ships, and towing vehicles.
An insulated wire or wires having a protective casing and used for transmitting electricity or telecommunication signals.

DSL
DSL is defined as an abbreviation that stands for digital subscriber line which is defined as the way a computer connects to the Internet at high speeds using telephone lines. An example of DSL is the phone service that might be down when your Internet connection isn't working.

SATELLITE
An artificial body placed in orbit around the earth or moon or another planet in order to collect information or for communication.

WIRELESS
Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path. Some monitoring devices, such as intrusion alarms, employ acoustic waves at frequencies above the range of human hearing; these are also sometimes classified as wireless.
