What types of modification during the maintance phase do you know? Describe them.
● Corrective modification: fixing errors and defects in the system's code or functionality.
● Adaptive modification: modifying the system to adapt to changing requirements or to accommodate new hardware or software.
● Perfective modification: improving the system's performance, reliability, and maintainability by adding new features or capabilities.
What is an encryption?
Encryption is the process of converting information into a secret code, which can only be decrypted using a key. Using encryption can help protect sensitive data from unauthorized access.
What are future trends in Information Systems?
• Artificial Intelligence (AI)
• Blockchain Technology
• Internet of Things (IoT)
• Cloud Computing
•Cybersecurity
What types of testing do you know? Descride them.
1) Unit Testing - testing one procedure or function of the software.
2) Integration Testing - testing 2-3 procedures or functions to test their interaction.
3) System Testing - testing whole system.
4) Acceptance Testing - determines to what degree an application meets end users' approval. Depending on the organization, acceptance testing might take the form of beta testing, application testing, field testing or end-user testing.
What are the considerations, that should be taken during the maintenance phase?
● Availability of resources: having the necessary resources and personnel to carry out maintenance tasks.
● Documentation: keeping accurate and up-to-date documentation of system components and their interdependencies.
● Change management: implementing a formal change management process to ensure that changes are properly evaluated, tested, and approved.
● Communication: maintaining open communication channels between maintenance personnel and system users to ensure that issues are addressed promptly.
What does VPN stand for, and what is it used for?
A VPN (Virtual Private Network) can help to protect your internet connection by encrypting your online activity and routing it through a remote server.
What is blockchain technology used for?
Blockchain Technology can be used
• for secure transactions, such as online voting
• for managing supply chains and logistics
• to provide insights to help organizations make informed decisions
What are the organisational stages of the Implementation phase? Describe them. What people are involved in the process?
Stage 1. Strategic planning. Top managers of the company should formulate their business goals and strategy for the next 1-2 years.
Stage 2. Organizational design. Briefly, clearly for top managers, it should be described – which tasks will be automated and how.
Stage 3. Optimization of business processes - the practice of optimizing existing processes to make them more efficient, which in turn leads to more productive and cost-effective processes.
What does the Quality of Service refers to? What metrics are used to measure it?
Quality of service refers to the level of performance and availability of the system.
Metrics used to measure quality of service may include:
- Mean time to repair (MTTR): the average time it takes to fix a system failure.
- Mean time between failures (MTBF): the average time between system failures.
- System availability: the percentage of time the system is operational and available for use.
- Customer satisfaction: feedback from system users on the system's performance and usability.
How does two-factor protection works?
Two-factor authentication adds an extra layer of security to your accounts by requiring you to enter a code sent to your phone or another device in addition to your password.
