What Makes A Smile‚ Smile? A wise man said a good smile could light up the entire room. So what is the secret behind a good smile? There are many factors that play a crucial role in structuring a “good” smile. First and foremost‚ one needs to be aware that “facial beauty is based on the principles of symmetry‚ proper alignment‚ and proportions of the face” (Davis‚ 299). The notion of symmetry‚ proper alignment‚ and proportions of the face also transitions into a smile and how it’s formed. Don’t

Write ’T’ if the statement is true and ’F’ if the statement is false. 1) With the introduction of the computer the need for automated tools for protecting files and other information stored on the computer became evident. 2) There is a natural tendency on the part of users and system managers to perceive little benefit from security investment until a security failure occurs. 3) There are clear boundaries between network security and internet

two types of cryptographic schemes available on the basis of key. They are: Symmetric Key Cryptography: This cryptographic scheme makes use of a single key for the encryption and decryption of the message [1] . Asymmetric or Public Key Cryptography: This cryptographic scheme makes use of two keys for encryption and decryption of the message‚ known as the public key and private Key [1] . We can classify Symmetric key cryptography into two types on the basis of their operations as: • Stream
