[Audio] Ergonomics is the science of designing and arranging people, technology and work environment to make them comfortable and efficient. It includes the study of the effects of computer use on the user, such as keyboard design, chair adjustments, and lighting in the computer room. This isn't related to processing speed. Software that converts a program written in a low-level language into machine code is called a compiler. Some modern PCs are dual core, meaning that the computer's processor has two independent processing units that can execute two sets of instructions at the same time. The term 'word wrap' refers to the feature of word processing programs that allows us to type continuously without pressing the ENTER key for each new line. Logic gates are logic circuits that receive one or more inputs, and return a single output. We can understand their operation through truth tables that show the output state for each possible combination of inputs. In the truth table shown, the logic gate used is the AND gate, which returns a result of 1 only if both of the inputs are 1. Finally, an example of a logical operator is the less-than symbol, ‘<’, which checks whether one value is smaller than another..

[Audio] Regarding radiation hazards, a common source is attributed to cathode ray tube monitors. When it comes to data transmission, if the rate is 3 bytes per second, then the number of bits transmitted in 10 seconds is 240 bits. A machine language is a programming language that uses instructions in the form of binary codes. For information systems design, the computer programmer is the person who writes software to be used by different users. Additionally, the use of capital letters in an e-mail is considered poor netiquette because it gives the appearance that the sender is shouting..

[Audio] The question of greatest strength when it comes to passwords can be answered with Option D: Food4allin - due to its high complexity; it contains both letters and numbers and is much harder to guess than something like Calvin's birthday or 123456.
