001) Difference between Phishing and Pharming 

Phishing is a type of attack on a computer device. In phishing, the attacker tries to find the sensitive information of users by the means of electronic communication illegally. 

Pharming is a more advanced technique to get users’ credentials by making effort to enter users into the website. In order words, it misdirects users to a fake website that appears to be official and victims give their personal information at fault. 

002) Sample resolution (the number of bits per sample) determines how many gradations of amplitude (corresponding to loudness) can be represented in the digital waveform. ... Link  

003) In some common digital audio formats, the amplitude of samples is recorded digitally with basic data types (e.g., integers) with specific number of bytes and bits. Thus, the sampling resolution can also be called bit depth or bit resolution (number of bits per sample). .... Link 

003) Remember, 0 pixel value always denotes black color. But there is no fixed value that denotes white color. .... In case of 1 bpp, 0 denotes black, and 1 denotes white.

In case 8 bpp (bits per pixel), 0 denotes black, and 255 denotes white. .... Link  

004) Thats how an image size is calculated and it is stored. .... Link
