The term "data" refers to information or facts that are stored electronically and not physically. In the given question, the blank space is asking for a word that describes software as something that is stored electronically and not physically. Among the options provided, "data" is the most suitable choice as it accurately describes the nature of software. Software is not a tangible object but rather a collection of data and instructions that can be processed by a computer.

The correct answer is "instructions" because software refers to a collection of programs or code written in a computer language. These programs or code are a set of instructions that provide specific commands and tasks for the hardware to execute. The software instructs the hardware on how to perform various operations and functions based on the given instructions.

A device driver is a software that allows hardware devices to communicate with the computer's operating system. It acts as a translator between the hardware and the operating system, enabling them to understand each other and work together seamlessly. Without device drivers, the operating system would not be able to recognize or control the hardware devices connected to the computer. Device drivers play a crucial role in ensuring proper functionality and compatibility between hardware and software components.

Application software refers to a type of software that is designed to perform specific tasks or functions for the user. It is different from system software, which is responsible for managing and operating the computer system. Application software includes programs like word processors, spreadsheets, graphic design tools, and web browsers, among others. These programs are created to meet the needs and requirements of users, allowing them to accomplish specific tasks efficiently and effectively.

Facial recognition is indeed a type of Artificial Intelligence (AI) biometrics. It uses AI algorithms to analyze and identify unique facial features of individuals, allowing for accurate identification and authentication. This technology has various applications, ranging from unlocking smartphones to enhancing security systems. By leveraging AI, facial recognition systems can continuously learn and improve their accuracy over time, making them an integral part of biometric identification systems.

Quantum cryptography is a branch of quantum physics that focuses on using principles of quantum mechanics to secure communication. It involves using the properties of quantum systems, such as the uncertainty principle and quantum entanglement, to create encryption protocols that are theoretically unbreakable. By harnessing these quantum properties, it is possible to make a message unintelligible to any unauthorized user or hacker, hence making the statement true.

A compiler is a computer program that translates a program written in a high level language into machine code. High level languages are designed to be easily understood by humans and are closer to natural language, making it easier for programmers to write code. The compiler takes this human-readable code and converts it into machine code, which is a low-level language that can be directly executed by the computer's hardware. This process allows the program to be executed by the computer and perform the desired tasks.

The next generation of smartphones will use touch screens with OLED technology, which will be coated with a crystalline layer. This layer will enable the phones to harness solar power, allowing them to be partially powered by the sun. This advancement in technology will make smartphones more energy-efficient and reduce their reliance on traditional power sources.

A phablet is a type of tablet that is designed to be a hybrid between a tablet and a smartphone. It typically has a larger screen size than a smartphone but smaller than a traditional tablet, making it easier to use for tasks such as browsing the internet, watching videos, and playing games. The term "phablet" is a combination of the words "phone" and "tablet," highlighting its dual functionality.

A linker is a computer program that puts all the modules together to form the final program. It takes the object code generated by the compiler and combines it with other necessary libraries and modules to create an executable file. The linker resolves external references, assigns memory addresses to variables and functions, and performs other tasks required for the program to run correctly. Without a linker, the individual modules of a program would not be able to communicate with each other and the program would not be able to execute.

The statement is true because one of the disadvantages of PCs is the need to copy files onto portable storage or send them via email when working in a different location. This can be inconvenient and time-consuming compared to using cloud storage or having access to files from any device.

CAT, which stands for Computer-Assisted Translation, indeed utilizes two tools: Terminology D.B (Database) and Translation Memories. These tools are designed to assist translators in their work by providing access to a database of terminology and previously translated segments. The Terminology D.B helps maintain consistency in the translation by providing a centralized repository of approved terms, while the Translation Memories store previously translated segments for reuse, saving time and effort. Therefore, the statement "CAT uses 2 tools: Terminology D.B and Translation memories" is true.
