Answer: review; quality
Explanation:
SQA refers to the ongoing process that can be found in the Software Development Life Cycle whereby the developed software is checked in order to ensure that the desired quality measures are met. The SQA processes is vital as it checks for the quality in every development phase.
The first step of the SQA process is to (review) the software development process. The next step is to set (quality) attributes.

Answer:
a simple IF statement using Regex
Explanation:
In any coding language, a good control procedure for this would be a simple IF statement using Regex. In the IF statement you can grab the account code and compare it to a regular expression that represents the correct format. IF the account code is in the correct format (matches the regular expression), then you go ahead and save the account code for use. Otherwise, you would output an error and ask for another account code. This will prevent the program from trying to use an account code that is not valid.
Answer:
b. Combatant Command
Explanation:
The Combatant commands are commands which are primarily authorized by the Secretary of Defense with approval from the President. They are then executed by the Combatant Commanders (CCDR's), who receive information from the higher authorities through the Chairman of the Joint Chiefs of Staff.

Answer:
(b) Windows is an open source operating system (<em>This is not correct</em>)
Explanation:
Option a is <em>correct</em> because Xerox PARC(Palo Alto Research Center), which is a subsidiary of the Xerox corporation, has been greatly responsible for invention and development in modern computing devices. Some of these developments are in Ethernet and graphical user interface (making use of menus, icons e.t.c).
Option b is <em>not correct</em> because Windows Operating system is not an open source operating system. Open source OS means users can interact with the driving code of the OS and make modifications. Windows does not support this feature. Operating systems that are open source include Linux and OpenSolaris.
Option c is <em>correct</em>. An operating system has two main components - the kernel and the user interface. The core component of an operating system is the Kernel as it interacts directly with the hardware and manages system resources. The user interface on the other hand allows users to interact with the kernel of the operating system using texts and/or graphics as commands.
Option d is <em>correct</em>. Linux operating system is an open source OS. Therefore, the source code is made available to the public for examination and modification.
