A worm is a type of malicious code that can distribute itself without using having to attach to a host file. Unlike a virus, which needs to infect an existing program or file to spread, a worm can create copies of itself and send them to other devices through a network. A worm can consume network bandwidth, slow down the system performance, or deliver a payload that can damage or compromise the security of the infected device. According to the CITM study guide, a worm is ''a self-replicating program that does not alter files but resides in active memory and duplicates itself'' (p. 70). Some examples of worms are Stuxnet, Conficker, and Blaster.Reference:

A relation is a type of association that describes how two or more entities are related to each other. A relation can have different properties, such as cardinality, optionality, and directionality, that specify the nature and constraints of the association. A relation can also have attributes that store information about the association. For example, a relation between Employee and Project entities can have an attribute called Role that indicates the role of each employee in each project. A relation can be represented by a line connecting the entities in an entity-relationship diagram (ERD).Reference:Association and Associative entity - IBM,When to use Associative entities? - Stack Overflow, [Entity-Relationship Model - Tutorialspoint].

Sequential interdependence occurs when the output of one unit or group becomes the input for another. This type of interdependence requires coordination and communication among the units or groups involved, as any delay or error in one unit can affect the performance of the next unit.An example of sequential interdependence is an assembly line, where each stage of production depends on the previous one12Reference:

Tangible costs are those that can be easily quantified and measured, such as direct expenses or physical assets. However, in some cases, tangible costs savings can be difficult to estimate because they depend on various factors, such as the expected life cycle of the asset, the depreciation rate, the maintenance costs, the opportunity costs, and the market conditions. For example, if a company invests in a new production machine, the tangible cost savings would be the difference between the cost of the old machine and the cost of the new machine, plus the additional benefits of the new machine, such as higher output, lower energy consumption, and improved quality. However, these benefits may not be easy to measure or predict, especially in the long term. Therefore, tangible costs savings can be difficult to estimate in some cases.Reference:Tangible Cost: Meaning and Difference From Intangible Costs - Investopedia,What Are Tangible Costs?

The spiral model is a software development lifecycle model that extends the waterfall approach by recognizing the different cycles of planning, risk analysis, engineering, and evaluation. The spiral model allows for iterative and incremental development, where each cycle produces a prototype or a deliverable that can be evaluated by the customer and the project team. The spiral model also incorporates risk management throughout the project, as each cycle involves identifying and resolving potential risks before proceeding to the next cycle. The spiral model is suitable for large, complex, and uncertain projects that require frequent feedback and adaptation.Reference:
