CANNIBALS AND MISSIONARIES


In the right bank of a river three missionaries and three cannibals are being about passing to the left bank of the river, they exist a boat in the one that alone two people can be transported. The game consists on to carry out or to execute a sequence of logical order so that all pass to the left bank. Keeping in mind that the cannibals eat human meat, you won't be able to leave in each bank a smaller number of monks to that of cannibals because these they will be devoured by the cannibals. If you are able to transfer these 06 characters until the left bank you will have achieved the objective.
IT PRESSES HERE TO CONNECT YOU TO THE GAME
It follows the following instructions
It selects cannibals & missioneries
1. PLAY SELECTS
2. It selects two cannibals and GO presses!
3. A cannibal of the boat selects and GO presses!
4. A cannibal of the right bank that is not in the boat selects and GO presses!
5. A cannibal of the boat selects and GO presses!
6. The cannibal of the boat selects and two missionary of the bank Selects, GO Presses
7. It selects a missionary of the boat and a cannibal of the bank and GO presses!
8. Select or cannibal of the boat and a missionary of the right bank and GO presses!
9. Select the two missionaries of the boat and then the cannibal of the left bank and GO presses! 10. A cannibal of the right bank selects and GO presses!
11. A cannibal of the boat selects and GO presses!
12. Select or cannibal of the right bank and GO presses!
13. It selects the two cannibals. Did you achieve it? Congratulations

ANOTHER GAME OF LOGIC

Wolf, sheep and cabbages


This amusing logic game consists on transporting a wolf, a sheep and a box of cabbages from the right bank of a river until the left bank for a boatman in its boat of one in one. Keeping in mind the nutritious likes from each one of the animals to happen, you should find the logical order so that these they happen if comersen among if.
It is very easy, it presses here to play and it follows these instructions.

He/she chooses wolf sheep & cabbage.

PLAY presses

1. It selects the sheep and GO presses!

2. It selects the sheep again so that it gets off the boat and GO presses!

3. It selects the wolf so that it ascends to the boat and GO presses!

4. It selects the wolf again so that it gets off the boat

5. It selects the sheep so that it ascends to the boat and GO Presses!

6. It selects the sheep again so that it gets off the boat
7. It selects the box with cabbages so that they go up to the boat and prersiona GO!
8. It selects the box again with cabbages so that they lower and GO presses!
9. It selects the sheep so that it ascends to the boat and GO presses!
10. It selects the sheep again so that it gets off the boat .Happiness have gotten it
If you find different forms of passing it you inform me it.

DATABASE

domingo, 22 de febrero de 2009

A database or database is a dataset belonging to oneself context and stored systematically for its later use.
DO YOU KNOW THAT IT IS ACCESS?

But for not tiing with concepts, I want to stress that the normal thing is that Access allows to be defined and to negotiate a database Jet of Microsoft. What we usually call a database Access, in fact is a database Jet that is included in any system Microsoft. With Access we can create this type of databases that you/they stay generally in files .mdb, and to negotiate them through the application. Access has numerous methods and assistants to define any element of the database, as the charts, the consultations, the forms, etc. and to carry out the administration and management of the data.

LOGICAL FUNCTION EXCEL (AND)



This function usually uses jointly with the function If. He/she allows to be carried out instead of a several question. And he/she will only be carried out the argument located in the true part of the If in the moment that all the answers are true. It structures: And (he/she Asks 1; he/she asks 2; he/she asks 3;...) Example: In the cell A1, we will introduce the age and in A2 the person's stature measured in centimeters. In the cell A3 the text will appear it can happen" if the age is bigger than 16 years and it measures more than 150. In the case that some of the two conditions is not completed, the text will appear it cannot happen." =IF (AND (A1 > 16;B1 > 150); it can happen"; it cannot happen") he/she Observes that the whole function AND (...) it is written inside the first argument of the function If.

SOURCE OF POWER


In electronic, a feeding source or of being able to it is a circuit that transforms the alternating tension of the industrial net into a practically continuous tension.

KNOWING THE ALGORITHMS



The importance of an algorithm resides in showing the way to carry out processes and to solve mathematical problems mechanically or of another type. The same as the mathematical functions, the algorithms receive an entrance and they transform it in an exit, behaving like a black box. However, not all black box that transforms an entrance into an exit you can consider an algorithm: so that an algorithm can be considered as such, it should be an orderly, finite and defined (formalization of their behavior) sequence of instructions. This way you can continue and to predict the behavior of the algorithm for any possible (except for algorithms probabilistas that he/she usually has a different exit) entrance, starting from the pursuit of that sequence of instructions that like it is ordered and defined, he/she doesn't give place to ambiguities and their appearance can be continued.
The algorithm concept, although similar and obviously related, he/she should not made a mistake with the program concept. While the first one is the specification of a group of steps (operations, instructions, orders,...) guided to the resolution of a problem (method), the second is that group of operations specified in a certain programming language and for a concrete computer, susceptible of being executed (or compiled or interpreted). An algorithm, strictly speaking, it cannot be executed until it is implemented, either in a programming language, in an electric circuit, in a mechanical apparatus, using paper and pencil, or in some other computation model.
