Binary

Computers can represent really big numbers, but it all comes down to that they are represented by 0s and 1s. Collection of 0s and 1s is called binary numbering system.

Please think of cases, where you have only two choices. For example: true and false, yes and no, numbers 1 and 0. 

Numbers 0 and 1 are the smallest numbers that can be represented by a computer. These are called bits.

When these 0s and 1s are grouped together, then it is possible to represent more complex information.

We are used to decimal numbering system. Decimal numbering system has numbers 0 through 9. However we are not limited by numbers that have range from 0 to 9. We can represent more complex numbers, when we are using just numbers from 0 to 9. Same is true for binary numbers. Binary numbers can represent complex numbers.

Number 1 represents on state, and number 0 represents off state.

Binary numbers are grouped. With 8 positions, it is possible to have a number as high as 255. With 32 binary numbers, it is possible to have a number as high as 4 billion.

Other types of data can also de represented in binary format. For example it is possible to represent text, images. sounds, video in binary format.

Sound quality will depend on how many binary digits are used to represent the sound. More numbers mean higher quality of sound.

Errors

It is a good idea to send errors in production environment to error log. Errors may contain sensitive information. Even so errors maybe helpful to development team or to QA team, errors need to be suppressed in production environment for viewing by everyone. Errors are good way to troubleshoot an issue therefore only trusted people can have access to this information. If not a trusted person get an access to this information, this information maybe used against the company and for a personal benefit. What to do in a case when there are more servers than one? Even so it is possible to inspect the log files in a single server, however it is impossible to do so when there is more than one server is available and web traffic is redirected to a different server each time. Log aggregation is needed in this case. All of the logs will be send to a central location. Logs may contain sensitive information. Please consult your company lawyer of how long logs can be stored, because logs can be use...
