ICT Fundamentals and Technologies Quiz

Wi-Fi Technology and Wireless Communication

• Wi-Fi technology uses radio waves to transmit data between devices without cables.
• Operates on various standards like IEEE 802.11 for seamless connectivity.
• Enables devices like laptops, smartphones, and IoT devices to connect to the internet.

Operating System (OS) Importance

• An operating system is software that manages hardware and software resources on a computer.
• Acts as an intermediary between users and the computer hardware.
• Essential for running applications, managing processes, and facilitating user interaction.

Wired vs. Wireless Transmission Media

• Wired transmission uses physical cables (e.g., Ethernet, fiber optics); offers stable and high-speed connections.
• Wireless transmission uses radio waves, infrared, or microwaves; provides mobility and flexibility but may be prone to interference.

AI's Influence on ICT Systems

• AI enhances decision-making through data analysis, pattern recognition, and predictive modeling.
• Powers automation in processes, improving efficiency in ICT operations.
• Facilitates advanced technologies like machine learning and natural language processing.

Project Management Tools for IT Projects

• Software like Microsoft Project and Trello are widely used to track tasks and timelines.
• Collaboration tools such as Asana and Slack enhance team communication.
• Gantt charts and Kanban boards assist in visualizing project progress.

Benefits of 3D Printing

• Reduces manufacturing costs by minimizing material waste and time.
• Enables rapid prototyping, allowing for quick design iterations.
• Facilitates customization in design, catering to specific user needs.

Common Computer Storage Devices

• Hard Disk Drives (HDD) provide large storage capacity at lower costs.
• Solid-State Drives (SSD) offer faster data access speeds and greater durability.
• Removable storage like USB flash drives and SD cards enable portable data transfer.

Role of the CPU

• The Central Processing Unit (CPU) executes instructions from programs by performing calculations and processing data.
• Often referred to as the "brain" of the computer, it influences overall speed and performance.
• Consists of cores that handle multiple tasks simultaneously for enhanced efficiency.

Function of a Receiver in Communication Systems

• Receivers convert incoming signals into analog formats that can be processed by devices.
• Demodulation converts radio signals into usable data for interpretation.
• Extracts information through techniques like filtering and amplification.

Privacy and Security Issues in ICT Systems

• Vulnerabilities in software can lead to data breaches and unauthorized access.
• User privacy at risk through data collection and surveillance practices.
• Importance of implementing security measures like encryption and firewalls.

Key Considerations in Managing Large Databases

• Data integrity and consistency must be maintained for reliable information.
• Scalability is essential for accommodating growing amounts of data.
• Backup strategies and security protocols are vital for data protection.

HDD vs. SSD Comparison

• HDDs are based on spinning disks, while SSDs use flash memory for storage.
• SSDs are faster, more durable, and consume less power compared to HDDs.
• HDDs offer more storage capacity for lower costs, making them ideal for archival purposes.

Virtual Reality (VR) vs. Augmented Reality (AR)

• VR creates entirely immersive environments to simulate real or imagined experiences.
• AR overlays digital information onto the physical world, enhancing real-world interaction.
• Each technology serves different purposes in fields such as gaming, training, and design.
