SQL Injection:
Going into a website and changing the SQL behind the logging into something like WHERE (username = $username) or (1=1), making logging in (whatever the username or password) possible. However to do so the website script has to be unprotected or previously disabled to enable code editing.]]> 2018-03-21 08:04:10 UTC https://padlet.com/agourlay1/pp1p00sv7wud/wish/244391757 https://padlet.com/agourlay1/pp1p00sv7wud/wish/244391877 SQL Injection:
When SQL code is not protected for a login, SQL injection can be used. This is when the SQL code is changed to add a true argument to the statements to satisfy the query and allow access to the website.

Sound:
Microphone is used to convert analogue to electrical.
The signal is sampled - the height(amplitude) of the wave is measured at regular intervals.
The height of the wave is represented as a binary number.]]> 2018-03-21 08:04:23 UTC https://padlet.com/agourlay1/pp1p00sv7wud/wish/244391877 https://padlet.com/agourlay1/pp1p00sv7wud/wish/244396129 SQL Injection
An SQL injection is where a hacker would input code into the SQL script to manipulate the system allowing you access to restricted parts of a website e.g making it so they can always log into an account by adding when (1 = 1) for example as that is always true]]> 2018-03-21 08:18:58 UTC https://padlet.com/agourlay1/pp1p00sv7wud/wish/244396129 https://padlet.com/agourlay1/pp1p00sv7wud/wish/244396174 The injection of SQL code into a script to manipulate a system. This could include adding a variable which is always true, like 1=1, to gain access to a websites login.

This is when hackers manage to get into different websites and areas by getting hold of the SQL info. If they can get hold of the script behind a login system and change it to something that will always equal true then they will be able to bypass the system. For example 1=1]]> 2018-03-21 08:19:34 UTC https://padlet.com/agourlay1/pp1p00sv7wud/wish/244396422 https://padlet.com/agourlay1/pp1p00sv7wud/wish/244399171 ~How is sound digitised:
-Microphone is used to convert analogue electrical frequency
-The signal is sampled
-The amplitude is represented by a binary number
Sampling- Amplitude of the wave is recorded at regular intervals]]> 2018-03-21 08:28:21 UTC https://padlet.com/agourlay1/pp1p00sv7wud/wish/244399171 https://padlet.com/agourlay1/pp1p00sv7wud/wish/244399196 -microphone to convert analogue to electrical(voltage)

- The amplitude is represented by a binary number.]]> 2018-03-21 08:30:21 UTC https://padlet.com/agourlay1/pp1p00sv7wud/wish/244399654 https://padlet.com/agourlay1/pp1p00sv7wud/wish/246783485 Sound Digitisation-
to convert an analogue sound to digital first a sound will need to have been recorded into a microphone which converts the analogue into electrical. then the amplitude is sampled at regular intervals]]> 2018-03-28 07:03:55 UTC https://padlet.com/agourlay1/pp1p00sv7wud/wish/246783485 https://padlet.com/agourlay1/pp1p00sv7wud/wish/246783506 Microphone is used to convert analogue to electrical.
