Study Notes
Types and Sources of Information
- Data collection can be internal (from within the organization) or external (from other organizations).
-
Primary sources:
- Original works like poems, diaries, court records, interviews, surveys, and original research.
- Scholarly research published in academic journals.
-
Secondary sources:
- Descriptive or analytical materials such as dictionaries, encyclopedias, and textbooks.
- Books and articles interpreting or synthesizing original research.
-
Tertiary sources:
- Organization tools for primary and secondary sources including indexes and abstracts.
- Databases provide online access to citations and sometimes digital copies of resources.
Research Question Development
- Select a topic of genuine interest and conduct preliminary research.
- Analyze the target audience to tailor the research questions accordingly.
- Progress through a series of evaluative questions to refine the main research question.
Types of Questions
- Open-ended questions: Allow for detailed responses and deeper insights.
- Closed-ended questions: Require brief answers like yes/no; preferred in surveys for easier statistical analysis.
Data Types
- Quantitative data: Numerical data suitable for mathematical analysis, must be current and reliable.
- Qualitative data: Non-numerical data reflecting thoughts, observations, and opinions, often obtained through open-ended questions.
Sampling Techniques
- Census: Collecting information from all individuals in a small organization.
- Judgment or Convenience Sampling: Selecting a specific group, suitable for more extensive organizations.
- Random sampling: No predetermined selection pattern; ensures diverse representation.
- Systematic sampling: Reduces variance in estimates by spreading out sample selection.
Server Types in Large Networks
- File and Print Servers: Manage access to files and printers.
- Application Servers: Host client/server applications and data for clients.
- Mail Servers: Manage email data flow similar to application servers.
- Fax Servers: Handle fax traffic and share fax modem resources.
- Communications Servers: Facilitate data flow and email between various networks.
- Directory Services Servers: Allow users to locate and secure information on a network.
Identifying Business Requirements
- Business requirements justify project initiation and outline expected benefits for stakeholders.
- Can be documented in project charters, business cases, or vision statements.
Network Analysis
- A network analyzer integrates hardware and software to monitor network performance.
-
Key components:
- Hardware: Predominantly software-based, compatible with standard OS and NICs; some systems analyze hardware faults.
- Capture Driver: Captures raw network traffic and filters desired data.
- Buffer: Temporary storage for captured data, can employ methods like round-robin for efficient data management.
- Real-time Analysis: Offers immediate analysis of incoming traffic data for prompt evaluations.
