Chapter 8, Problem 12PSA
Explanation of Solution
Internet of Things (IoT):
IoT is the internet of things which contains a system of interrelated computing devices, which has the ability to transfer data over a network. It is an idea where the objects can interact with other devices or applications when connected to the internet.
Numerous companies are aiming to design and develop the products with the features of automatically communicating with other devices and exchanging data. It is used in various fields such as home automation, vehicle operations,
Some home automation devices evolved using IoT:
Smart TV:
Smart Television is an IoT enabled television sets which are designed with internet features. This allows the user to access the internet applications, streaming providers and interactive services.
Light bulbs:
IoT enabled light bulbs make use of a “bridge” which allows connecting smart phones or tablets into the light bulbs. The light bulbs have been programmed based on the preference of lighting. Lights bulbs can be switched off by using smart technologies.
Refrigerators:
Smart refrigerators generate the next iteration in food storage technology and improve the easiness of storing the food. The technologies used in the refrigerators scan the barcode and intimate the expiration date and send the data to the phone.
Air conditioners:
IoT enabled air conditioners are connected to the smart phone which is used to tune temperature. This can be achieved by remote access.
Thermostat systems:
Thermostat systems are used to control heat in the homes. It is the recent innovation in IoT. It controls the heat level by remote access...

Question D.4: FIFO Page Replacement
Consider the following page reference string:
e, c, b, e, a, g, d, c, e, g, d, a
Considering 4 frames, fill in the following table and then answer how many page faults would occur with the
FIFO page replacement algorithm.
RS: reference string; FO: frame 0, F1: frame 1, etc.
Hint: all frames are initially empty, so your first unique pages will all cost one fault each.
