Quality Assurance (QA) in Software Testing: QA Views & Best Practices

Software quality can be hard to determine. That’s because each person involved can define quality differently. A range of perspectives, from different stakeholders and entities, may measure software quality in terms of how it fits to their own requirements, expectations, and standards.

Quality Assurance (QA) is a common practice to ensure that the end product of any Software Development Lifecycle (SDLC) conforms to the overall and scope-agreed expectations.

In this article, we will discuss the basics of Quality Assurance (QA) and its role in software testing.

What is quality assurance?

To define quality assurance, let’s first start with the definition of quality:

Quality refers to the conformance to implicit or explicit requirements, expectations, and standards.

In order to fulfil these requirements, a quality control mechanism is set up.

Quality Control (QC) is the process through which you achieve, or improve, product quality. The QC process can also include the activities used to eliminate waste processes in the SDLC. QC functions involve a range of testing activities used to detect and resolve technical issues. These are followed together with the development processes over the course of the SDLC.

Enterprise Networking Explained: Types, Concepts & Trends

Think of the Enterprise Network as the internet, except that it’s local to your organization.

An enterprise network helps employees and machines communicate, share files, access systems, and analyze the performance of an IT environment that drives business operations. Enterprise networks are configured to:

  • Connect a limited number of authorized systems, apps, and individuals.
  • Enable a secure and efficient communication channel to perform specific business operations.

In this article, we will discuss the enterprise network, how it helps the business, and industry-proven best practices to run secure, high performance, and highly dependable enterprise networking systems.

What is the enterprise network?

The term ‘enterprise network’ refers to the physical, virtual, or logical connectivity infrastructure that enables systems and apps to:

  • Communicate
  • Share information
  • Run services and programs
  • Analyze system performance

The enterprise network effectively comprises the infrastructure, hardware and software systems, and the communication protocols used to deliver end-to-end services. The network (or its subset) may be architected, designed, deployed, optimized, and configured to perform a unique set of business and technical objectives.

To establish an enterprise network at geographically disparate locations, use Virtual Private Networks (VPNs) to connect these regions.

Comparing Lower Layer Splits for Open Fronthaul Deployments - Cisco Blogs

The transition to open RAN (Radio Access Network) based on interoperable lower layer splits is gaining significant momentum across the mobile industry. However, where best to split the open RAN is a complex compromise between radio unit (RU) simplification, support of advanced coordinated multipoint RF capabilities, consequential limitations on transport delay budgets as well as bandwidth expansion. This post compares the two leading alternative splits for realizing an interoperable open RAN.
