Explanation:
An Extranet extends an organization’s internal network to provide controlled access to external users such as suppliers, vendors, and business partners. It uses security mechanisms like authentication and encryption to ensure that only authorized external parties can access the relevant internal resources.
Option A (Intranet): Internal-only network for employees; not accessible to outside users.
Option B (VPN): Provides secure remote connections for users but does not inherently grant controlled access to internal systems for external organizations.
Option C (LAN): A local network limited to internal devices in a small geographic area.
Thus, the correct type of network is an Extranet.

Explanation:
A Solid-State Drive (SSD) uses flash memory technology to store data electronically, allowing faster data access, lower latency, and improved reliability compared to mechanical storage devices. SSDs have no moving parts, making them more durable and efficient for high-speed computing tasks.
Option A (Hard disk drive): Uses spinning magnetic disks and is slower.
Option B (Optical disc drive): Reads/writes data using lasers on discs (CDs, DVDs).
Option D (Magnetic tape drive): Stores large volumes of data sequentially, primarily for backups.
Thus, the correct answer is Solid-state drive.

정답:
Explanation:
The Processor (CPU C Central Processing Unit) is the “brain” of the computer. It controls operations and executes instructions, performing arithmetic, logic, control, and input/output operations as directed by the program instructions.
Option A (Hard drive): Provides long-term storage, not operations control.
Option B (RAM): Stores data temporarily for quick access but does not control operations.
Option C (Graphics card): Handles rendering of images and video, but does not serve as the primary system controller.
Therefore, the processor is the component that carries out operations and manages execution.

정답:
Explanation:
Computer-aided engineering (CAE) software provides the ability to design, simulate, and test how a product will perform under a variety of physical conditions (such as stress, heat, vibration, or fluid flow) before the product is manufactured. CAE tools reduce development costs, minimize risks, and allow engineers to optimize product performance digitally.
Option B (Predictive analytics): Focuses on forecasting future events using statistical models, not physical product simulation.
Option C (Supply chain management): Manages product flow, suppliers, and logistics, not engineering simulations.
Option D (Asset management): Tracks and manages physical assets throughout their lifecycle, not pre-construction product testing.
Thus, the correct answer is Computer-aided engineering.

정답:
Explanation:
An Enterprise System is designed to integrate and manage the core business processes of an organization across different departments within a single unified digital platform. It enables seamless information sharing, coordination, and communication across functions such as finance, human resources, supply chain, sales, and customer service. By centralizing data and processes, enterprise systems help eliminate silos, reduce duplication of effort, and ensure that decision-making is based on accurate, real-time information.
Option A (Project management) is incorrect because project management software is intended for scheduling, task tracking, and collaboration on specific projects, not for cross-departmental integration of business processes.
Option C (Transaction processing system) is incorrect because a TPS is designed to handle day-to-day business transactions efficiently, such as order entry or payroll, but does not integrate operations across departments.
Option D (Data analysis platform) is incorrect because while data analysis platforms provide insights and support decision-making, they do not unify business processes or coordinate operations across multiple departments.
The Enterprise System, often in the form of Enterprise Resource Planning (ERP), is the correct solution because it streamlines operations, promotes cross-departmental collaboration, and supports integrated decision-making in line with organizational strategy.

정답:
Explanation:
A primary key in a relational database table is used to uniquely identify each record in that table. It enforces entity integrity by ensuring that each row can be distinguished from every other row. A primary key must contain unique values and it cannot contain NULL values. This guarantees that every record is distinct and can be retrieved, updated, or related to other records efficiently.
The primary key serves as the central reference point when creating relationships between tables through the use of foreign keys, thus enabling referential integrity within the database. Without a primary key, it would not be possible to maintain consistent and reliable relationships across different tables.
Option A is incorrect because connecting tables to external systems is not the role of a primary key; this function is handled through integration tools or middleware.
Option B is incorrect because managing user access is controlled by database access control mechanisms, not primary keys.
Option D is incorrect because improving storage efficiency is related to data normalization, indexing, and storage optimization, not primary key assignment.
Therefore, the correct function of a primary key is to identify each record in a table uniquely, ensuring data integrity and reliable referencing across the database.

정답:
Explanation:
Linux is an open-source, Unix-like operating system widely used for servers, cloud computing, and high-performance workstations. It offers flexibility, security, and customization, making it the preferred choice for enterprise and web hosting environments.

Explanation:
SNMP (Simple Network Management Protocol) is used for monitoring and managing network devices such as routers, switches, and servers. It allows administrators to gather network performance data and configure devices remotely.

정답:
Explanation:
In a bus topology, all devices share a single central cable (backbone). If this cable fails, the entire network becomes inoperable. This topology is simple and cost-effective but lacks redundancy.

정답:
Explanation:
ROM (Read-Only Memory) is a type of non-volatile memory that permanently stores firmware and critical system instructions, such as BIOS. Unlike RAM, ROM retains data even when power is turned off.

Explanation:
Flash memory is a type of non-volatile rewritable memory that is compact and portable. It is commonly used in USB drives, SSDs, and memory cards. Unlike RAM, which loses data when power is off, flash memory retains stored information even without power.

정답:
Explanation:
Simulation is a prototyping method that replicates how a system or solution would function in real-world scenarios. It allows businesses to test various data inputs, business rules, and operational conditions before full implementation. This method helps identify potential issues and optimize decision-making.
