the codes are designed to provide only minimum

security requirements for performing tasks. Codes

usually governed the important parts of what isbeing done.

property of the emerging dangers of the use of electricity. Electricity codes attempt to

provide the following:

Protection against electric shock

Protection against failures of current, where out of voltages are unforeseeable routes

to land also unpredictable ways

Protection from heat effects of electric current

Protection against the current envelope

Protection against the envelope voltage

has the opposite, produce a thermalgradiante applying you a current (Peltiereffect), electric moving heat from one sideto the other (heat pump), making that youone is cool and other hot

performance is much lower than anyother conventional refrigerator andtherefore is used only in smallrefrigerators.

Protection against sobre-corriente

Protection against current envelope is very similar to that used incircuit television, if about resistance circulates a stream notproducing a voltage drop at their ends more than.6 Volt transistorremains in court and off protection.

CLASSIFICATION of the pins pins of an integrated medium-power are classified asfollows: voltage components and integrated voltage these component signalcomponents have 4 power, two direct inputs and two on the resistance of 100 ohmtype oxide cash to feed the internal preamplifiers

positive voltage output, this is enough to put in driving part above (whichdetects positive VCD) transistor polarized in direct connection to UnionB-E, which enters saturation and sends the 5 volts on Earth, by enablingthe protection which team moves to block ignition.

WHATARE LOCAL, NATIONAL AND INTERNATIONAL

STANDARDS

17/41

The American National Institute of standards (ANSI) is a

private organization that manages and coordinates thesessment of compliance and voluntary standardization

for the United non-profit. The ANSI itself does not

develop standards. facilitates the development by

establishing consensus among qualified groups

processes.

the IEEE is a leading authority in technical

areas ranging from computer engineering,biomedical technology and telecommunications

to electrical energy, the aerospace and

consumer electronics

IEEE 802.3 (Ethernet standard)

This standard describes the series of digital bits that

travel over the wire. Ethernet is unique in its way to

access cable. IEEE 802.3 and variants get use of the

cable to compete for him. This system is called multiple

access with carrier detection and collision detection

(CSMA/CD, Carrier Sense Multiple Access with Collision

Detection).

yStations: computers or devices with wireless interface .

yMedia: you can define two RF and infrared .

yAccess point (AP): has the functions of a bridge (connects two networks

with similar or different levels of link), and is therefore relevant frame

conversions .

yDistribution system: important because they provide mobility between APfor frames between different points of access or terminals, help is the

mechanic that controls where the station is to send the frame.

STANDARDSTIA EIA

TIA/EIA-568-B tries to set standards that will allow thedesign and implementation of wiring systems for

commercial buildings and between buildings on

campus environments .

The main standard TIA/EIA-568-B.1

defines general requirements, while...

TIA/EIA-568-B.2 focuses on balanced

pairs cable systems components andthe - 568 - B.3 addresses components

of fiber optic cable systems.

modular RJ-45connector pins are

numbered 1 to 8, still

pin 1 of the left end of

the connector and pin8 on the far right .

there are many other organizations that have

developed international standards which are then

adopted by others.

activity between EIA and NEMA to discuss standardization of discrete

semiconductor devices; in 1970was expanded to include integrated circuits

Resumen

Standards ensure that wiring work according tospecifications. Organizations that developstandards also serve as industry leaders todetermine if new technologies are compatible with

existing ones, and whether they meet the objectiveslaid down by those who develop such technologies.Check regularly updates or revisions to the

standards of the following organizations forStandardization
