The correct answer is 'C. Portable computer' because all the devices listed in the question - notebook, laptop, palm, and hand-held computers - are designed to be easily carried and used on-the-go. These devices are lightweight, compact, and have built-in batteries for portability, distinguishing them from desktop computers which are stationary. Therefore, they fall under the category of portable computers.
The correct answer is 'A. Tim Berners-Lee' because he is widely recognized as the inventor of the World Wide Web. Tim Berners-Lee developed the first web browser and web server software in 1990, laying the foundation for the modern internet as we know it today. His contributions revolutionized the way information is shared and accessed globally.
The correct answer is 'Assembly languages' because they are considered low level languages due to their close correspondence with machine code and hardware. Assembly languages provide direct control over the computer's hardware and memory, making them more closely tied to the machine's architecture compared to higher level languages. This makes them more efficient for tasks that require direct manipulation of hardware resources.
The correct answer is 'B. input device' because a keyboard or mouse are both examples of input devices that are used to input information into a computer system. Input devices are specifically designed to allow users to enter data or commands into a computer for processing. Therefore, the term 'input device' accurately describes the function of devices like a keyboard or mouse in this context.
The correct answer is 'B. Web2.0 applications are focused on the ability for people to collaborate and share information online' because Web2.0 applications are known for their emphasis on user-generated content and interaction. These applications allow users to actively participate in creating and sharing content, fostering collaboration and information sharing among users. This characteristic distinguishes Web2.0 applications from earlier versions of the web that were more static and focused on one-way communication.
The correct answer is 'C. Database' because a database is specifically designed to store and organize data in a structured way, allowing for easy access, retrieval, and utilization of the stored information. Unlike other options, a database is a specialized tool that is optimized for managing and manipulating large amounts of data efficiently.
The correct answer is 'C. Insta notes' because it is not a commonly used platform for personal communication on the internet. While options like email, social media, and messaging apps are widely used for personal communication, 'Insta notes' does not have the same level of popularity or recognition in this context. Therefore, it stands out as the correct choice for something that is not a means of personal communication on the internet.
The correct answer is 'C. Programs' because compilers and interpreters are software tools that process code written in high-level programming languages into machine code that can be executed by a computer. They are essentially programs themselves that facilitate the translation and execution of code. Therefore, 'Programs' accurately describes the nature of compilers and interpreters in this context.
The correct answer is 'A. To navigate through web pages quickly' because Caret Browsing allows users to move the cursor using the keyboard, making it easier to quickly navigate through text on a webpage. This feature is especially helpful for individuals who have difficulty using a mouse or trackpad, as it provides a more efficient way to browse and interact with content on the web.
The correct answer is 'B. 100 Mbps' because Ethernet LAN typically operates at this speed, which stands for 100 Megabits per second. This speed allows for efficient communication between devices on the network, ensuring smooth data transfer and connectivity.
