Define bioinformatics and give an example of the data used in medical research.
Outline one feature of fuzzy logic which makes it suitable for medical diagnosis.
Calculate, showing your working in each case:the binary (base 2) value of the denary (base 10) number: 105.
Calculate, showing your working in each case: the hexadecimal (base 16) value of the denary (base 10) number: 200.
Construct a logic diagram for the following expression.
NOT A OR (A AND B)
Colours are represented by a computer as a combination of the three primary colours: red, green and blue.
Numerical values are used to represent the different shades of each primary colour. These values range from 0 to 255 in decimal, or 00 to FF in hexadecimal.
State why hexadecimal numbers are frequently used in computing.
State the number of bits used to represent a non-primary colour, such as yellow.
State the maximum number of colours that can be represented in a computer pixel.
A self-driving car relies on a series of lasers and cameras that combine with high definition maps to give a three-dimensional (3D) view of the environment. Rules are programmed into the system so that the car drives at an optimum speed, keeps a safe distance from any vehicle in front, uses fuel economically and follows the traffic regulations.
Outline the need for high definition maps held in memory.
Outline how analysing successive 3D images in memory helps the car to drive safely.
Outline the time and memory needs of 3D visualization in this situation.
Discuss the social implications of self-driving cars.
Copy and complete the following truth table where:
X = A XOR B
Y = A NOR C
Z = X OR NOT Y
Describe the function of the control unit (CU) in the central processing unit (CPU).
Calculate how many different colours can be represented using two hexadecimal characters.
Construct a logic diagram for the following Boolean expression.
NOT A OR (A AND B)
State the hexadecimal equivalent of the following binary number:
11011111
