Chapter 4, Problem 1.2CTQ
Identifying issues that could be solved by using mobile device management software.
Program Plan Intro
Mobile device management software helps students in managing their devices remotely. Mobile device management software is software which connects, manage, monitor, solve problems and secure mobile devices remotely.
Students often face various problems when using their devices which can be addressed with the use of device management software:
- Secure data in case of loss/theft of device: Mobile devices are easy target. In case of theft or loss of device, it can be locked, and data can be wiped off using mobile device management software so as to safe guard important data.
- Need of removal of application or data from devices: If some of the data or application needs to remove that can be done with the use of mobile device management software.
- Changing or adding passwords: Passwords can be easily broken. Using mobile device management software student can change the password remotely. So that any unauthorized person does not access device.
- Device misplacement: Mobile device management software is great tool which helps in tracking phone by finding its location and making it ring.
- Upgrading phone: With mobile device management software there is no need to upgrade the phone manually, do that using mobile device management software with number of extra controls.
All these issues can be addressed easily with the use of device management software if loaded and linked properly.

Q.1. Architecture performance [10 marks]
Answer
A certain microprocessor requires either 2, 4, or 6 machine cycles to perform various operations.
⚫ (40+g+f)% require 2 machine cycles,
⚫ (30-g) % require 4 machine cycles, and
⚫ (30-f)% require 6 machine cycles.
(a) What is the average number of machine cycles per instruction for this microprocessor?
Answer
(b) What is the clock rate (machine cycles per second) required for this microprocessor to be a
"1000 MIPS" processor?
Answer
(c) Suppose that 35% of the instructions require retrieving an operand from memory which
needs an extra 8 machine cycles. What is the average number of machine cycles per
instruction, including the instructions that fetch operands from memory?

Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: 1 kilogram = 35.274 ounces 1 kilogram = 2.20462 pounds 1 pound = 0.453592 kilograms 1 pound = 16 ounces 1 ounce = 0.0283 kilograms 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters.
