First in-class post

Well I'm posting from within room 114...

Mr. Mohan started by speaking a bit about whether we are sure if IT is the area we want to go into, and mentioned about possible alternatives if needed.

He then started into discussions about accuracy vs relevance, with arguments being held with the lecturer and one of the students about whether cost-effectiveness is an attribute or not.

He then launched into a small discussion about if a value is non-existant, that it does not make that value irrelevant. An example to the contrary was given about a cat born without ears, but in my view, if a cat is born with no ears, then the fact that there are no ears present becomes a relevant attribute.

We then started talking about Data hierarchies, and how data is determined by electrical voltages, with a binary 1 being a high voltage, and a binary 0 being a low voltage. This was then followed by talking about bits, bytes, kilobytes, Megabytes etc.

We finished up with discussions about how characters form fields, and how the fields would have names (attributes) as well as values.

Well class is done, so until Thursday.
