+Hash függvény, Hash tábla, Hasító tábla
+    A hash egy rögzített hosszúságú érték, amelyet egy matematikai képlet segítségével állítanak elő.
+    A hash értékeket adattömörítésben, kriptológiában stb. használják.
+    Az adatindexelésében a hash értéket használjuk, mert rögzített hosszúságúak, függetlenül a generálásukhoz használt értékektől.
+    Lehetővé teszi, hogy a ......
 
+    A hah fgvény egy matematikai algoritmust alkalmaz a kulcs hash-é alakítására.
+    Az ütközés akkor következik be, ha egy hash függvény ugyanazt a hash értéket állítja elő több kulcshoz.
 
+Hash tábla
+    A hash tábla egy olyan adatstruktúra, amely kulcs értékpár használatával értéket tárol.
+    Minden értékhez egydi kulcs van hozzárendelve, amelyet egy hash függvény segítségével állítanak elő.
 
+    A kulcs neve a hozzá tartozó érték elérésére szolgál.
+    Ez nagyon felgyorsítja az értlkek keresését a hash táblában,
+    függetlenül a hash táblában lévő elemek számától.
+
+Hash funkciók
+    Például, ha az alkalmazottak nyilvántartásait szeretnénk tárolni,
+    és minden alkalmazott egyedileg azonosítható egy alkalmazotti szám segítségével.
+    Kulcsként használhatjuk az alkalmazotti számot,
+    értékként a munkavállalói adatokat rendelhetjük hozzá.
+
+    A hash függvény megoldja a fenti problémát azáltal, hogy lekéri az alkalmazottu számot,
+    és ennek segítségével generál egy hash egész értéket,
+    rögzített számjegyeket, és optimalizálja a tárhelyet.
+    A hash függvény célja egy kulcs létrehozása, amely a tárolni kívánt értékre hivatkozik.
+    A függvény elfogadja a mentendő értéket, majd egy algoritmus segítségével kiszámítja a kulcs értékét.
