What is a CDN and How Does It Improve Speed?

In today's digital world, every website owner wants his site to load fast and users to have a good experience. If a website is slow, visitors leave it quickly, which affects both traffic and business. The solution to this problem is CDN (Content Delivery Network) . But many people still do not understand what CDN is and how it increases the speed of our website. In this blog, we will learn step by step what CDN is, how it works and why it is important for modern websites. What is CDN? The full form of CDN is Content Delivery Network . It is a distributed network in which servers are spread across the world. These servers store copies of your website's content (such as images, videos, CSS files, JavaScript files, PDFs, etc.). When a user opens your site, the content is delivered to him from the nearest server. This makes the site load faster because the data does not travel from a far-off server. How does a CDN work? The working of a CDN is simple but the concept is powe...

What Is Bug Tracking?

Bug Tracking: The Cornerstone of Quality Software

Bug tracking, also known as defect tracking or issue tracking, is the systematic process of identifying, documenting, monitoring, and resolving bugs or errors within software applications. It's an essential part of the software development lifecycle (SDLC), ensuring that the final product is of high quality, free from critical issues, and meets user expectations.




The Bug Tracking Process: A Closer Look

1.Bug Identification:

Manual Testing: Testers meticulously examine the software, looking for deviations from expected behavior.
Automated Testing: Specialized tools automatically execute tests and flag inconsistencies.
User Feedback: End-users report bugs they encounter while using the software.





2.Bug Reporting:

  • Detailed Documentation: Each bug is documented with specific information:
  • Summary: A concise description of the issue.
  • Steps to Reproduce: A clear sequence of actions to replicate the bug.
  • Expected Behavior: The intended outcome of the software.
  • Actual Behavior: The observed, incorrect behavior.
  • Severity: The impact of the bug on the software's functionality (e.g., critical, major, minor).
  • Priority: The urgency of fixing the bug (e.g., high, medium, low).
  • Screenshots or Videos: Visual aids to better illustrate the issue.

3.Bug Assignment:

Designated Developers: Bugs are assigned to specific developers responsible for fixing them.
Clear Communication: The bug tracker facilitates communication between testers, developers, and project managers.

4. Fixing Bugs:

Debugging: To identify the source of the issue, developers examine the code.
Code Modification: To resolve the problem, the required code modifications are applied.

5. Verification of Bugs:

Retesting: To make sure the problem has been rectified, testers run the corrected code again.
Regression Testing: To make sure the repair hasn't created any new issues, further tests are run.





6. Bug Fix:

Status Updates: The bug tracking system updates the bug's status (e.g., fixed, closed, reopened).
Historical Records: For future use, the bug report is preserved.

The Importance of Bug Tracking

  • Better Software Quality: Bug tracking contributes to the delivery of a more stable and dependable product by proactively finding and fixing defects.
  • Improved User Experience: End users have a more seamless and pleasurable experience when a software program is free of bugs.
  • Lower Costs: It is far less expensive to fix issues early in the development cycle than it is to fix them after the product has been released.
  • Enhanced Productivity: More team cooperation and communication result from streamlined bug tracking procedures, which boost output.
  • Data-Driven Decision Making: Trends, future development priorities, and overall software quality may all be improved by analyzing bug tracking data.



Common Tools for Tracking Bugs
Jira GitHub Problems

Trello's Bugzilla MantisBT

To sum up, bug tracking is an essential procedure in contemporary software development. Businesses may greatly improve the quality of their software, increase user happiness, and more successfully accomplish their goals by putting in place a strong bug tracking system and following a clear procedure.

How to Implement a Robust Data Backup Strategy?

Putting in place a robust data backup plan is essential to safeguarding your company against data loss brought on by hacker attacks, system malfunctions, or human error. Here's how to put together a reliable backup plan: 1. Determine Vital Information Determine which data is most important for business operations first. Give important intellectual property, financial records, and customer records top priority. https://globalclassified.net/0/posts/3-Services/24-IT/2402359-setup-brother-com.html https://globalclassified.net/0/posts/3-Services/24-IT/2402370-setup-brother-com.html 2. Apply the 3-2-1 Guideline Use the 3-2-1 backup strategy: store two copies of your data on various types of storage, maintain one copy off-site or in the cloud, and maintain three copies of your data (two backups and your production data). 3. Put Backup Procedures in Motion Reduce human error and guarantee consistency by automating backups. Based on the criticality of the data, schedule regular backups to h...

What is two-factor authentication?

Image
The Protection of Your Digital Life with Two-Factor Authentication (2FA) Taking proactive measures to protect our online accounts is crucial in today's increasingly digital environment, when our private information is always in danger. A strong security feature that provides an additional degree of protection, two-factor authentication (2FA) makes it much more difficult for unauthorized users to access your accounts.  Two-factor authentication: what is it? Two forms of identification are needed to confirm your identity as part of the 2FA security process. This implies that a second factor is still required to access your account even if someone knows your password. You may have something, know something, or be something as this second aspect.  Typical 2FA Techniques 1. TOTP, or time-based one-time password: How it operates: Every 30 seconds, a unique code is generated via a time-based code generator software on your phone, such as Authy or Google Authenticator.  Benefits ...
