“Network topology can simply be defined as the arrangement of the elements (links,
nodes, etc.) of a communication network”.
With reference to the foregoing statement, use a well labelled diagram, describing any three types of Network topologies and highlighting their advantages and disadvantages.
Assume you are a Network Administrator in your organisation who has been faced with various network-related issues, and have managed to resolve them effectively.
Discuss any ten (10) Network-related issues and the corresponding troubleshooting steps/ approach that you have adopted to resolve these issues. Use appropriate diagrams, images or screenshots where applicable in order to enhance your explanation.
Determine whether ( 𝑝∨𝑞)∧(𝑝→𝑟)∧( 𝑞→𝑠)→𝑟∨𝑠 is a Tautology or a contradiction using a truth table
Give full truth table
Give the observation of each container.
Container 1-25 ml of liquid soap in 100 ml distilled water
Container 2-25 ml of liquid soap in 100 ml tap water
A 100 nC charge is placed at the origin. A -50 nC charge is placed at x= 5 cm and a 200 nC is placed at x= -10 cm.
What is the net electrostatic force acting on 200 nC charge?
A wound coil that has an inductance of 180mH and a resistance of 35 is connected to a 100V 50Hz supply calculate the impedance of the coil the current the power factor and the apparent power consumed
Explain the difference between colonisation, infection and disease
A container holds 2 moles of a diatomic gas at temperature T = 420K. At this temperature,
rotational motions (but not vibrational motions) of the gas molecules are allowed.
(a) What is the total internal energy of this gas? (2)
(b) A quantity of energy E = 300 Joules is transferred to the gas. What fraction of this added
energy is responsible for increasing the temperature of the gas? (1)
(c) How much did the internal translational energy increase, and thus how much did the temperature
of the gas increase? (4)
(d) Explain how the predictions from particle statistics fail, when describing the heat capacities
of a diatomic ideal gas.
Prove for all integers a and b, if a mod 8 = 5 and b mod 8 = 3 then ab mod 8 = 7.
Prove for every integer n, n4 has the form 8m or 8m + 1 for some integer m. Hint: Use 2 cases.
