it is made up of:fields, registries and archives,
Field :it is the set of elements that compose a registry,
Registry: the set of related fields to each other
File: the union of several registries that contain fields such.we can understand to Access, like a computer science program with which it is possible to be managed different related files, made up of registries.
Consultations: it is one of the objects most useful of the data base Access, since by means of them we can select to information (registries) of a base data, according to certain conditions fixed by us. The result of a consultation always is record number that fulfills the criterion specified by the user.
Macros: A macro is an object that allows to automate of a fast form and simple a series of actions that made of normal way would tolerate several steps.

The systems of uninterrupted energy UPS consist basically of three main modules, that can be of internal or external form to the housing of the equipment:
I modulate of control, that acts the rectification as, I modulate of transformer which provides diverse voltages depending on the capacity, 120VAC, 208VAC, 220VAC, 480VAC etc. and the one of batteries that give to the endorsement of necessary time of operativity and protection and that according to he himself can give greater or smaller endorsement of autonomy in time.
How works the Ups?
This one device of uninterrupted energy is placed between the exit of an electrical service of alternating current normal and the equipment to protect that they go from computers, workstations, datacenters, telecommunications, etc. that they require to be protected of blackouts, reduction of line tensions and other events.
The UPS takes the energy from an alternating current of entrance, soon a switch detects the level of entrance energy and a battery simultaneously this loading itself to be used in case of fault of the power plant.
When coming out of the UPS any device can be connected, ej. A computer, with the purpose of making the certain protection.
The UPS this designed to be monitoreado at the moment from a port RS-232, a port USB or a SNMP/Web card, some is even controlled with telephone connection sending signals via email, directions IP or to a direct telephone line, this becomes thanks to a software that allows to control to the UPS.
Classification and Selection of the UPSAccording to its capacity:
from 350VA to 1500VA. For protection of 1 to 3 computers approximately. (3)Average capacity:
between 1500VA and 6000VA. Para protección de equipo con aplicaciones medias o sofisticadas.
High capacity:
from 6000VA to 120KVA, happening through commonly used in Rooms of Servants of 10KVA, 20KVA and 30KVA. (4)
According to its endorsement:
The Modules or Banks of batteries that give the time autonomy to the UPS can be of internal or external type to the UPS. They can endorse from the common thing (15 minutes) to periods between 2 and 8 hours. Banks of batteries have been made so falsified and for applications so you criticize of up to 1000 hours continuous of work (5). Obvious you lie greater amount of Banks is the cost of the UPS will be increased. The Batteries have a approximate life utility of 3 to 5 years.
According to its Forma:
The UPS can be of type Rack/Mount or Torre. In the case of? Rackeables? these are used in Frames that to their better distribution and organization allow. Used in financial organizations. Those of type tower are similar to the CASE or CPU of a computer, but when the capacities exceed to 10KVA of consumption, by its size frequently they are type tower being able to even arrive at the 15 feet of height.
According to its technology:
Passive stand by: It obtains the energy directly of the commercial network and, simultaneously batteries are being loaded through a rectifier. In case of failure in the feeding, the feeding of the load exchanges and it is obtained energy from the batteries through an investor. Some have internally Regulation of Voltage and Suppression of tips. They are of low cost and for applications of Low Capacity.
Interactive line: they also know like Smart UPS, among them count those of? double conversion? similars to on Line. While there is feeding of the network, the batteries will be loaded through an investor; when it fails this feeding the energy is obtained from the batteries, with times of very short transference to battery from 2 to 4 mseg. and the current crosses the investor of opposite form to like did during his load. The wave it simulates to the wave sine, called Presses Width Modulated PWM. Used in average applications.
Online: These UPS are continuously loading and providing energy directly from the batteries. Based on transfer time 0 mseg. the equipment connected at no moment detects it. Internally they have regulation of Voltage, suppression of tips, double conversion of energy that it transforms the wave into AC to DC and soon it reconverts it DC to AC purified, indicating of status and software of monitoreo. Its cost in some cases are greater to the previous ones so that its application is directed for protection of sensible, special equipment, of critical data, etc. They are end technology and its application is for high Capacities.
Main Characteristics to Comprar a UPS
Connectors that they allow the use of external modules of batteries to prolong time of operation.Suppresors internal of voltage that avoid abrupt ascents of voltage.Regulation of voltage.Equipment with special power outlets that can be controlled from software and that allows to reinitiate or to disconnect the system.Port of communications RS-232 that allows to execute ignition commandos and extinguished.SNMP/Web groove to conduct remote operations of dull and reiniciaciones.Connection for Special equipment of Humidity Measurement.Automatic switches who protect the equipment and the UPS against short circuits as much of entrance as of exit.Extinguished of emergency for equipment of 6KVA and 10KVA (by pass) made by means of a modular connection that allows to carry out dull remote of emergency.Permanent single-phase connection of entrance and exit.Switch of derivation for maintenance tasks.Indicators of light type LEDS or additives.Softwares of Monitoreo.Guarantee by manufacturer of 2 years, tensile.CARD SNMP WEB CARD
Advantages To use a UPS.
It provides security and protection to its equipment.· Preparation in line to filter noises of an electrical source.· Suppression of voltage against tips and sobrevoltage of energy in the line electrical.· Protection against falls or reduction of line tension.· Backup power I continue during considerable periods of time.· Alarm systems or notification.
Cause/Effect/Solutionfaults
common in supply companies of energy, disconnections accidental and intentional of the line of tension, deficient design of the circuits, overload, inadequate maintenance services, stop voltage in lines, radio trasmisiones, connections of apparatuses and even fluorescent lights can cause in our companies from the degradation slow electronics, defective video, blockade of systems, low productivity, the lost one of the active data, fall of the system, or even catastrophic damage of the equipment. The definitive solution for all these problems are definitively an equipment UPS.
To make the Connection of a UPS.
connection must be taken preferably from a line dedicated to the UPS and without they exist current inductive like generators of motor type near. Equipment UPS of low capacity (until 1500VA) is of type Plug and Play. Single it is necessary? to connect them? and? to ignite them. It must at least to let load the batteries 12 Hours before his operation. For equipment of high capacity one becomes necessary to make adjustments in the electrical attack specific like near sub-boards, suitable wiring, etc. Made necessarily by a technician specialized in the area that the connection of the UPS will also make and his modules.It is not necessary to connect to the UPS a protector of voltage or regulator (AVR) and preferably one is not due to connect simultaneously Investors/Shipper

Techniques for the formulation of algorithms.
The two tools used commonly to design algorithms are:
1.Diagrama of Flow
2.Pseudocódigo
A flow chart is the graphical representation of an algorithm. Also it is possible to be said that it is the representation detailed in graphical form of how the passages must be made in the computer to produce results.It is graphical representation occurs when several symbols (that indicate different processes in the computer), are related to each other by means of lines that indicate the order in that the processes are due to execute. The used symbols have been standardized by the North American institute of normalization (ANSI).
Recommendations for the design of Flow charts.
· Lines of horizontal and/or vertical flow are due to only use.· The crossing of lines is due to avoid using the connectors. Connectors are due to use single when it is necessary.· They do not have to be left lines of flow without connecting.· The symbols so that they are possible to be read of above towards down and of left to right are due to draw up. - All text written within a symbol will have to be written clearly, avoiding the use of many words. Pseudocodigo.· Mixture of programming language and Spanish (or English or any other language) that are used, within the structured programming, to make the design of a program. En esencial, el pseudocodigo se puede definir como un lenguaje de especificaciones de algoritmos. It is the narrative representation of the steps that must follow an algorithm to give solution to a certain problem. The pseudocode uses words that indicate the process to make.
Structured diagrams (Nassi-Schneiderman).
· Structured diagram N-S also known as diagram of chapín is like a flow chart in which the union arrows are omitted and the boxes are contiguous. The successive actions can be written in successive boxes and like in the flow charts , different actions in a box can be written.
