What is the difference between dependability and reliability?

Reliable is a person that can be trusted. Dependable is a person to which one can depend. If a machine is reliable, it usually means a part of it is reliable and is contributing to the whole machinery that is dependable.

What is dependability of a software?

In systems engineering, dependability is a measure of a system’s availability, reliability, maintainability, and in some cases, other characteristics such as durability, safety and security. In real-time computing, dependability is the ability to provide services that can be trusted within a time-period.

What is difference between software reliability and hardware reliability?

Software reliability tends to change continually during test periods. While hardware reliability may change during certain periods such as initial burn in or the end of useful life however it has a much greater tendency then software value.

What is the difference between reliability and validity?

Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.

What are some examples of dependability?

• Communication.
• Meeting deadlines.
• Taking initiative.
• Being detail-oriented.
• Following company policies.
• Teamwork.

What is software reliability and availability?

The measurement of Availability is driven by time loss whereas the measurement of Reliability is driven by the frequency and impact of failures. Mathematically, the Availability of a system can be treated as a function of its Reliability. In other words, Reliability can be considered a subset of Availability.

What is dependability research?

Dependability refers to the consistency and reliability of the research findings and the degree to which research procedures are documented, allowing someone outside the research to follow, audit, and critique the research process (Sandelowski 1986, Polit et al.

What are the differences between reliability and validity in research?

What is the difference between reliability and validity with examples?

Reliability implies consistency: if you take the ACT five times, you should get roughly the same results every time. A test is valid if it measures what it’s supposed to. Tests that are valid are also reliable. The ACT is valid (and reliable) because it measures what a student learned in high school.

What is the difference between reliable and dependable?

Let’s take a closer look. The difference between reliable and dependable is that dependable is a more decisive distinction of reliability. Dependability is sure to happen when really needed instead of merely happening consistently, as reliablility implies.

What is software reliability and why is it important?

Software Reliability is the probability of failure-free software operation for a specified period of time in a specified environment. Software Reliability is also an important factor affecting system reliability. It differs from hardware reliability in that it reflects the design perfection, rather than manufacturing perfection.

What is the difference between reliability and dependability in psychology?

Answer Wiki. Well, reliability is the trust you have on someone to do something. While dependability means that you want someone to do something because of your inability to do so yourself.

Is it hard to make software more reliable?

While any system with a high degree of complexity, including software, will be hard to reach a certain level of reliability, system developers tend to push complexity into the software layer, with the rapid growth of system size and ease of doing so by upgrading the software.
