Quality Assurance and Management: Concepts and Principles
Quality Assurance and Management
Q. Definition:
- Comparative Sense (Degree of Excellence): On a relative basis, products can be ranked or referred to by “grade”.
- Quantitative Sense (Used in Manufacturing/Production Release/Technical Evaluation): Refers to quality level.
- Fitness for Purpose Sense: Evaluation of a product’s or service’s ability to satisfy a given need.
Gap Between Perception & Expectation
Expected Service = Word of Mouth + Personal Needs + Past Experience (manufacturer -> specification

1G = 109, 1M = 106, 1K = 103, 1B = 1 Byte = 8 bits, 1b = 1 bit. Msec is millisec which is 0.001.
Delays
Types of delays: processing, queue, transmission, propagation.
dnodal = dproc + dqueue + dtrans + dprop
Dial-up networks have high transmission delays, while satellite connections have high propagation delays.
Processing Delay
Time it takes for a device to process a packet header to determine where to forward it (caused by CPU cycles).
Queue Delay
Time a packet waits in a system queue before processing,

Debian Linux: Configure Network Interfaces as a Bridge/Network Switch
My server has five Ethernet ports and one ADSL port. How do I set up an IPv4 software bridge using Debian Linux so that the five ports act as a network switch?
You need to use the brctl command to bridge network connections under Debian Linux. This is useful for:
- Sharing your internet connection between multiple devices.
- Increasing your ethernet jacks capacity without purchasing a dedicated network switch.
- Setting up Debian as an access

Evolution & Scope of the QA Concept
A. Inspection-Oriented Assurance
Initially, quality assurance (QA) was heavily focused on inspection. Japan banned defective products, while the West and Hong Kong equated QA with inspection. This stemmed from the assumption that strict supervision of workers was necessary, leading to the creation of independent inspection divisions. The authority of inspectors increased, as did the percentage of inspectors compared to line workers (1-5% in Japan, 15% in the

Ch. 1, 2, 3 Key Terms:
A Relation is a 2D table with rows and columns. Columns contain attributes, each with a unique name and the same datatype. Rows contain data about cases, cells hold one value, and no two rows can be identical.
Relational Databases join tables together using values to:
- Reduce redundancy
- Preserve relationships
- Allow for partial data
Keys represent data in a relational database and are one or more columns that identify a row. Composite keys contain 2 or more columns.
