The highest, followed by proper nouns and it pronouns in, is also high on the frequency of use of the prefix.
From the distribution of letters in the word, there are some rules. Frequency end of the 90 per cent are concentrated in the word in English, the total use of the semi-vowels y, w, 90% are concentrated in the beginning of the word, p and c in the beginning of the word, in the end less, r h in the middle of a word more, and j and q do not appear in the end of the word outside the abbreviations. We can continue to study the frequency characteristics of these holders levy for broken Chak single table instead of the password for the great help.
2, the connection characteristics
A second important feature of the language is connected to be imposed. In English, the back of the letter q in addition to the connection ellipsis. Almost 100% connected with u, this is the connection after the connection characteristics.
Similarly,oakley polarized sunglass, some letters, they are in front, always like connection so few letters. For example, the connection is almost always in front of the letters of the alphabet x i and e, only in very few circumstances is o and a, which is connected to the first connection in the characteristics.
Connection to be levy in addition to the former connection, connection, there are - kind of intermittent connections, such as between c and e, r high frequency.
Ciphertext encrypted with a classic encryption methods, even if the ciphertext to grasp without too much use of connection holding sign, decrypt greater grasp.
3, repeat feature
More than two character strings recurring phenomenon called repeat characteristic of the language. In English, th, - tion,oakley womens sunglasses, tious, etc. is repeated string.
Repeat characteristics in a very long attracted the attention of the people. In 1602, the Italian Giovanni. Benny Botta found in the password to use the Virginia side table, repeated ciphertext character strings often represent recurring expressly letter string. 1863, Friedrich of Prussia. Casey Sharansky seize this phenomenon, the invention of the estimated cyclical multi-table instead of the password length of the key words The ammunition is an important part of the weapons and equipment used for the effective strength of the direct killing, destruction of technical equipment, the destruction of various buildings and the completion of a special task.
