A. Wi-Fi

B. Bluetooth

C. Zigbee

D. NFC

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.

92. Operating system is

A. Hardware

B. Software which manage resources of the system

C. Software which performs computation

D. None of the above

An operating system (OS) is software which manages resources of the system. Explanation: Definition: An operating system is a software program that acts as an intermediary between computer hardware and software applications. It manages computer hardware resources and provides common services for computer programs. Functions of an Operating System: Resource Management: The OS allocates resources such as CPU time, memory, disk space, and input/output devices to running programs or processes. Process Management: It manages processes (running instances of programs), scheduling them for execution, and providing mechanisms for inter-process communication. Memory Management: The OS handles memory allocation and deallocation, ensuring efficient use of available memory resources. File System Management: It manages files on storage devices, providing mechanisms for file creation, deletion, access, and organization. User Interface: The OS provides a user interface (UI) that allows users to interact with the computer and run applications. Types of Operating Systems: There are different types of operating systems, including: Desktop Operating Systems: Examples include Windows, macOS, and Linux distributions like Ubuntu. Server Operating Systems: Such as Windows Server, Linux distributions like CentOS, and specialized server OS variants. Embedded Operating Systems: Found in embedded systems like smartphones (Android, iOS), IoT devices, and other specialized hardware. Contrasting with Other Options: Hardware: Operating systems interact with hardware to manage and utilize resources but are not hardware themselves. They enable software to communicate with hardware components effectively. Software Which Performs Computation: While operating systems facilitate execution of programs and manage resources, they themselves do not perform computations directly beyond system-level tasks. Importance: Operating systems are crucial for enabling users to interact with computers and for coordinating the efficient use of hardware resources. They provide an abstraction layer that simplifies the development and execution of software applications. In summary, an operating system is essential software that manages hardware resources, facilitates communication between software and hardware components, and provides a platform for running applications on a computer system.

118. What is the binary representation of the decimal number 7?

A. 111

B. 1000

C. 1101

D. 1010

The binary representation of the decimal number 7 is 111. Here's how it breaks down: To convert the decimal number 7 into binary, you repeatedly divide the number by 2 and note the remainder until the quotient becomes zero. Start with 7: 7 divided by 2 gives a quotient of 3 and a remainder of 1. 3 divided by 2 gives a quotient of 1 and a remainder of 1. 1 divided by 2 gives a quotient of 0 and a remainder of 1. Reading the remainders from bottom to top gives us 111 in binary. Therefore, the binary representation of decimal 7 is 111.
