Lecture 1- Intro Flashcards
What is analog information?
Information that comes from or is stored on a continuously variable medium; cannot be reproduced
What is digital information?
Discrete information that can be reproduced perfectly
What is perfect reproduction?
Data can be copied exactly the same way over and over again with no floating point errors
What is degradation recovery?
When a signal degraded, it can be fully recovered. This is found in digital information
What is boolean logic?
True or false
What is data?
Quantities, characters, or symbols on which operations are performed by a computer, being stored and transmitted in the form of electrical signals and recorded on magnetic, optical, or mechanical recording media.
What is information?
When data is processed, organized, structured or presented in a given context so as to make it useful, it is called information.
What is an integrated circuit?
A complex electronic circuit, built into a silicon semiconducting chip base. The primary parts are transistors, resistors, capacitors, and diodes
What is an integrated circuit capable of?
Receiving a signal, processing it and producing output.
What does a transistor do?
It regulates current or voltage flow and acts as a switch or gate for electronic signals-0s or 1s
What dose a motherboard do?
It houses and connects all the components in a computer/laptop
From lowest to highest layer what are the layers of the software stack?
- Hardware
- OS kernel
- OS apps
- Apps
What is abstraction?
The simplification of a concept
What is an algorithm?
A precise set of instructions to execute, to solve a specific problem
What is the underlying goal of an algorithm?
To find the best possible way to do something effectively and efficiently
