ALGHORITHM

In mathematics and computer science, an algorithm (/ˈælɡərɪðəm/ is a self-contained sequence of actions to be performed. Algorithms can perform calculation, data processing and automated reasoning tasks.An algorithm is an effective method that can be expressed within a finite amount of space and timeand in a well-defined formal language[2] for calculating a function.[ Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finitenumber of well-defined successive states, eventually producing "output"and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.The concept of algorithm has existed for centuries; however, a partial

formalization of what would become the modern algorithm began

with attempts to solve the Entscheidungsproblem (the "decision

problem") posed by David Hilbert in 1928. Subsequent formalizations

were framed as attempts to define "effective calculability" or

"effective method";those formalizations included the Gödel–

Herbrand–Kleene recursive functions of 1930, 1934 and 1935,

Alonzo Church's lambda calculus of 1936, Emil Post's "Formulation

1" of 1936, and Alan Turing's Turing machines of 1936–7 and 1939.

Giving a formal definition of algorithms, corresponding to the

intuitive notion, remains a challenging problem.

1. PURPOSE

Practice about knowing alghorihm

Practice knowing what a flowchart and how use it based

on basic in data base

Practice knowing about create database on terminal in

XAMPP

Practice to work the quiz in last meeting

MODUL I

Flowchart

2. Basic teori

1. Flow

Flow is connector between prosedures and processes

2 .Connector

Connector is symblos out or sign in proseduresses or

processes inside sheet or the same page

3.Offline connector

Offline connector is. symblos out or sign in proseduresses or

processes inside sheet or not same page

Processing symblos:

Symbols that describe or indicate the type of processing operation in a procedure Process

Symbol showing the processing that the computer is doing

Descision

is Symbols for conditions that will generate some possible answers or actions

Prefined process

Symbol u prepares the storage to be used as a processing place in storage

1.

2.

Terminal

Symbol for the beginning or end of a program

Manual input

Symbol to enter data manually online keyboard

Input output symblos:

The symbol used to denote the type of equipment used as the input / output medium

Input – output

A symbol that states the input or output process regardless of the type of equipment

Database

Data base

1. Online data

2. Offline data

Example online data base ;

My SQL

SQL LITE ( OFFLINE DATA )

Oracle

ORM

Fire base

Data type :

Interger : 0,1,2,3,4,5,6 and so on Float : 2,5 and so on Double : 2,55 and so on Varchar : RIZKI , ARJUNA Char : R,I,Z,K,I

Operator sign :

= : equal != : not equal >= : bigger than

<= : small than % : mod / : divide * : multiply $$ : and ! : or

Bolean:

true : == false : !=

the name of application is XAMPP , you can start all

you must find terminal for ready make database.

you can write like that in your terminal after that you can klik enter in your keyboard

you can write in terminal “show databases;”

create database

example :

use the your name database

create table

desc the data base; for insert your database

select your database

insert multiple data

select coloumn

Make a flowchart to determine a student's Pass from his or her average grade. If the student's average score is> 70 then the student is graduated. If the average score is <70 then the student does NOT PASS. Input values of Mathematics, Bahasa Indonesia, English

Create an algorithm that receives incoming distance (s) and velocity (v), then outputs the time (t) required to travelFormula: t = v / s

Create algorithms and programs that include two integer values 10 and 6. Then perform arithmetic operations to two numbers

Create a flowchart to change the temperature in Fahrenheit to a temperature in Celsius with the formula ° C = 5/9 x (° F -32)
