LSI,VLSI & ULSI chips were used in which generation?
- Third
- Fourth
- Both (a) and (b)
- Second
Explanation: LSI (Large Scale Integration), VLSI (Very Large Scale Integration), and ULSI (Ultra Large Scale Integration) represent progressive stages in semiconductor technology. LSI integrated hundreds to thousands of transistors, VLSI packed tens of thousands to millions, and ULSI pushed further with hundreds of millions to billions of transistors per chip, revolutionizing computer and electronic device capabilities across generations.
VLSI is used in _________ Generation of computer
Explanation:
VLSI (Very Large Scale Integration) technology, introduced in the fourth generation of computers, integrates tens of thousands to millions of transistors onto a single chip. This advancement enabled the development of microprocessors, transforming computing by enhancing power, reducing size, and enabling the widespread adoption of personal computers and modern electronic devices.
What is the main function of an expansion card in a computer?
- To process data
- To provide additional storage
- To add or enhance hardware functionality
- To connect to the internet
Explanation: Expansion cards enhance a computer's functionality by adding specialized hardware capabilities beyond what the motherboard provides. They include graphics cards for high-performance visuals, sound cards for enhanced audio, network interface cards (NICs) for connectivity, and others like RAID controllers or USB expansion cards, tailoring the computer to specific user needs.
Which component of the CPU acts as a temporary storage for data and instructions frequently used by the CPU?
- Control Unit
- ALU (Arithmetic Logic Unit)
- Cache Memory
- Register
Explanation: Cache memory in a CPU acts as a high-speed buffer that stores frequently accessed data and instructions from RAM. This allows the CPU to quickly retrieve needed information without accessing slower main memory directly. Unlike registers, which hold data actively being processed, cache memory optimizes performance by reducing latency in data access for ongoing computations.
Which output device is commonly used for large-format printing of architectural drawings and posters?
- Dot matrix printer
- Laser printer
- Inkjet printer
- Plotter
Explanation:
Plotters excel in large-format printing of architectural drawings and posters due to their precision in producing detailed and scaled graphics on large media sizes, ranging from A2 to A0 and beyond. They offer specialized capabilities like using pens or inkjet technology tailored for technical illustrations and design professionals requiring high accuracy and quality.
Which IoT connectivity technology is known for its low power consumption and is commonly used in wearable devices?
Explanation: The IoT connectivity technology known for its low power consumption and commonly used in wearable devices is Bluetooth.
Explanation:
Bluetooth:
Low Power Consumption: Bluetooth, particularly Bluetooth Low Energy (BLE), is designed for low energy consumption. BLE is a power-efficient version of Bluetooth, making it ideal for devices that need to operate for long periods on small batteries.
Commonly Used in Wearables: Bluetooth is widely used in wearable devices like fitness trackers, smartwatches, and health monitors because of its ability to maintain connectivity over short distances with minimal energy usage.
Data Transfer: Bluetooth can transfer data efficiently between devices, which is crucial for the functionality of wearable devices that often need to sync data with smartphones or other central hubs.
Wi-Fi:
Higher Power Consumption: Wi-Fi consumes more power compared to Bluetooth. It is suitable for applications requiring higher data transfer rates and longer range but is not ideal for small battery-operated wearable devices.
Zigbee:
Moderate Power Consumption: Zigbee is known for its low power consumption relative to Wi-Fi but is more commonly used in home automation and industrial applications rather than wearable devices.
NFC (Near Field Communication):
Very Short Range: NFC is designed for very short-range communication (a few centimeters) and is often used in payment systems and access control rather than continuous data transfer in wearables.
Therefore, Bluetooth, especially Bluetooth Low Energy (BLE), stands out as the best fit for wearable devices due to its balance of low power consumption and sufficient range and data transfer capabilities.
Which of the following is NOT a common feature of online collaboration tools for document editing and sharing?
- Real-time collaboration
Explanation:
Social media integration is not typically a primary feature of online collaboration tools designed for document editing and sharing. These tools prioritize real-time collaboration, version history for tracking changes, and file synchronization across devices. While some may offer basic sharing options to social media, their core functionality revolves around document management and teamwork efficiency.
