Question

The personal laptop computer is a product that has proven to be very reliable in spite of the fact that it has many interfaces, is operated by a variety of people, operates nearly continuously, and includes a number of internal moving parts (e.g., floppy disk drive, hard drive, and CDROM drive(s)). It is a portable device that operates in a wide range of environments (temperature, shock, vibration, etc.). List six design features or characteristics that contribute to the laptop reliability. For each item in your list, estimate the contributions this item has on the overall computer cost. A ranking of high, medium, and low is sufficient.

Explanation / Answer

Some of the design features that contribute to the laptop reliability:

1.      Processor

2.      RAM

3.      Motherboard

4.      Battery

5.      Cooling system

6.      Charger

·         Processor: The processor type and its speed have an impact on the functioning and reliability of the laptop. Processor will have a high impact on cost of the overall cost of the computer. Based on the quality, type and speed of the processor as they increase, the cost increases.

·         RAM: The size of the RAM also has high impact on the cost. As the size increases, the cost of the RAM increases and hence the overall cost. It contributes high in the overall cost.

·         Motherboard: These will have a moderate cost impact on the overall cost of the computer. As these are standard and mostly not upgradable, the price will be standard and its impact will be moderate.

·         Battery: Battery life depends on the size and cost of the battery. It is one of the major components for ensuring reliability. It contribution in the overall cost is moderate.

·         Cooling system: Cooling is an important reliability issue. Though it is an important feature, the cooling system within a laptop does not contribute much in the overall cost of the computer. It can be ranked low.

·         Charger: A good charger within the computer is required for better and uninterrupted power supply. Based on the type and design of the charger, their cost varies. But it has a less contribution in the overall cost of the computer.
