Vertical cables connecting multiple floors in a building are called risers. They provide the backbone pathway for networking infrastructure between floors. 'Spans' typically refer to horizontal cable runs, not vertical ones.

Early Ethernet networks (like 10Base5 Thicknet and 10Base2 Thinnet) did transmit data over thick, heavy coaxial cables. These cables were bulky, difficult to work with, and had limited bandwidth compared to modern twisted-pair and fiber alternatives.

Windows 98 is a desktop operating system, not a network operating system (NOS). A NOS like Windows Server, Novell NetWare, or Linux is specifically designed to manage network resources, user authentication, file sharing, and other network services for multiple clients.

The OSI (Open Systems Interconnection) model has exactly 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. This is a fundamental networking concept that provides a framework for understanding network protocols.

A router acts as a 'traffic cop' by directing data packets between different networks based on IP addresses and routing tables. It makes intelligent decisions about the best path for packets, unlike a hub (which broadcasts to all ports) or a switch (which forwards based on MAC addresses within a network).

Fiber optic cables transmit data using light pulses through glass or plastic fibers, not electrical signals. This is one of their key advantages - they are immune to electromagnetic interference and don't conduct electricity, making them safer in certain environments.

In Cognos, mail server settings must be configured in Cognos Configuration, which is the administrative interface for server-level settings. This is where SMTP and other email parameters are defined.

When a report is renamed, any shortcuts pointing to it retain the original report name and the link becomes broken. Shortcuts do not automatically update to reflect the new name.

Cognos ReportNet uses a three-tier architecture consisting of the presentation tier (web interface), application tier (report server), and data tier (database access). This separation provides scalability and modularity.

Cognos ReportNet is a business intelligence tool that fully supports interactive reporting features, including drill down to see more detailed data and drill through to navigate to related reports.

Object diagrams provide a visual representation of object instances and their relationships at a specific point in time. Object Explorer allows navigation and modification of objects within a modeling environment. Together, these tools enable comprehensive modification of both objects and their relationships.

Query Studio displays queried data in a list format by default, which presents data in rows and columns similar to a spreadsheet. This is the simplest and most common way to view raw query results. Charts and other visualizations must be explicitly created after the initial data display.

The Verify option in Framework Manager checks packages for errors, inconsistencies, and potential issues before publication. This validation process helps identify problems early in the development cycle. Validate, Check, Diagnose, and Synchronize are not the standard package verification commands.

Report Studio can create List reports (tabular data), Cross-tab reports, Map reports (for geographic data), and Repeater reports (for repeated data patterns). View is a database or query concept, not a report type that can be created in Report Studio itself.

Report properties contain various settings for reports including the default language setting. This property allows specification of the language for report headers, prompts, and metadata. The file format option, Insertable Objects pane, data model properties, and Run with Options dialog do not contain default language settings.

The Usage property determines how a query item can be used in reports - as a fact, attribute, or identifier. This is the most critical setting to verify immediately after import because it affects how data can be aggregated and displayed. Format, Data Type, and Semi-Aggregate are important but secondary to Usage.

PowerCubes must be published through Framework Manager to make them available to Report Studio authors. Publishing creates the necessary package and metadata that Report Studio needs to access the cube data. IQD files are a legacy format and drill-through is a separate feature unrelated to basic access.

Validating a report checks for errors in queries, calculations, and references before execution. This is essential when running an existing report to ensure it will function correctly, especially if the underlying data source or package may have changed. Security access, checkout status, distribution settings, and synchronization are not pre-run requirements.

Cognos 8 uses a web-based zero foot-print architecture, meaning no client software installation is required on user machines. All processing occurs on the server, and users access Cognos through a web browser. This architecture simplifies deployment and reduces maintenance overhead.

When importing metadata, Framework Manager can automatically generate relationships between query subjects based on existing primary key and foreign key relationships in the database. This saves significant modeling time and ensures referential integrity. Multiple connections must be defined separately, usage is set manually, and join types are not automatically converted.
