The raw facts and figures that are entered into a computer system are referred to as data. Data can be in various forms such as numbers, text, images, or videos. It is the basic input that is processed and analyzed by the computer system to generate meaningful information. Material, information, and knowledge are not accurate terms to describe the raw facts and figures entered into a computer system.

Nanocomputers are the next generation of smaller, faster computers that are designed to fit into a single human cell. These computers utilize nanotechnology, which involves manipulating materials at the atomic and molecular scale. Nanocomputers have the potential to revolutionize various fields, including medicine, by enabling targeted drug delivery and precise diagnostics. They are expected to have significant advancements in processing power and efficiency compared to traditional computers.

Newspapers are not a part of cyberspace because they are physical printed publications and do not exist solely in the digital realm. Cyberspace refers to the virtual space where digital information is stored, accessed, and communicated, such as the internet, the world wide web, and other digital platforms. While telephones, the world wide web, and the internet are all components of cyberspace as they involve digital communication and information exchange, newspapers exist outside of this digital space.

Supercomputers are high-capacity computers with hundreds of thousands of processors that can perform more than one trillion calculations per second. They are specifically designed for complex and intensive computational tasks that require immense processing power. Unlike desktop computers, laptops, and workstations, supercomputers are capable of handling large-scale simulations, scientific research, weather forecasting, and other data-intensive applications.

A local area network is a system that connects a group of desktop PCs and other devices, such as printers, in a specific location, such as an office or building. It is usually connected by a special cable and allows these devices to communicate and share resources with each other.

A communications system connecting two or more computers is called a network. This is because a network allows computers to share resources, such as files and printers, and communicate with each other through data transmission. It enables the exchange of information and collaboration between multiple devices, whether they are connected through cables, telephone lines, or wireless connections. A network can be local, connecting computers within a limited area like a home or office, or it can be wide, connecting computers across different locations or even globally.

A byte is the unit of data storage that represents one character. It is the smallest unit of memory that can be addressed in a computer system. Therefore, one character of data is stored as one byte.

A computer is a programmable, multiuse machine that can take raw data and process it into meaningful information. It can perform various tasks and calculations based on the instructions given to it. With the help of software and applications, a computer can convert raw facts and figures into useful information that can be utilized for various purposes. Therefore, out of the given options, a computer is the device that fits this description.

The World Wide Web is a system of interconnected computers all over the world that supports specially formatted documents in multimedia form. It allows users to access and share information through web pages, which can contain text, images, videos, and other media. The internet, on the other hand, is the underlying network infrastructure that enables the communication between these computers. While the internet is the physical network, the World Wide Web is the software application that runs on top of it, making it the correct answer to the question.

Distance learning is the name given to online education programs. This method of education allows students to learn remotely, without the need for physical attendance at a traditional classroom. It involves the use of technology and online platforms to deliver educational materials, interact with instructors, and participate in virtual discussions and assignments. Distance learning offers flexibility and convenience, making it accessible to a wide range of learners who may not be able to attend traditional classes due to various reasons such as geographical distance, work commitments, or personal circumstances.

A server is a central computer that holds collections of data and programs for connecting or supplying services to PC's, workstations, and other devices. It acts as a central hub, providing resources and functionalities to other devices on the network. Servers are designed to handle multiple requests and manage resources efficiently, making them essential for network operations and data storage.

A kilobyte represents 1,024 characters of data. It is a unit of digital information that is commonly used to measure the size of computer files and memory. The prefix "kilo" indicates a multiplication factor of 1,024, which is 2^10. Therefore, a kilobyte is equivalent to 1,024 bytes.

The correct answer is printer, CD drive, DVD drive. These devices are considered peripheral because they are external to the computer system and provide additional functionality. A printer is used to produce hard copies of documents, while the CD drive and DVD drive are used to read and write data to CDs and DVDs respectively.

Personal computers are computers that are designed to be used by an individual for personal use. They are typically smaller in size and can be placed next to a desk, on a desk, or carried around. They are also available at a range of prices, from $500 to $5,000. Workstations, mainframes, and minicomputers are different types of computers with different capabilities and purposes.

The term "online" refers to the use of a computer or information device connected through a network to access information and services. This can include activities such as browsing websites, using online applications, accessing online databases, and communicating with others through various online platforms. It encompasses the idea of being connected to the internet and utilizing its resources for various purposes.

Personal digital assistants, also known as PDAs, are handheld computers that provide personal organization tools and email access. They are designed to be portable and convenient, allowing users to keep track of their schedules, contacts, and tasks, as well as access their emails on the go. PDAs are smaller and less powerful than notebook computers or supercomputers, and they are not as advanced as nanocomputers. Therefore, the correct answer for this question is personal digital assistants.

Scientists are working on a nanocomputer that will be the size of a pencil and more powerful than today's fastest supercomputer. A nanocomputer refers to a computer that operates at the nanoscale level, which is extremely small. This advancement in technology will allow for a significant increase in computing power and capabilities, surpassing the current capabilities of even the fastest supercomputers.

Tiny, specialized microprocessors installed in "smart" appliances and automobiles are known as microcontrollers. These microcontrollers are designed to perform specific tasks and are embedded within the devices they control. They are different from microcomputers, servers, and workstations, which are more general-purpose computing devices.

A peripheral device is a component that enhances a computer's input, storage, or output capabilities. It is an external device that can be connected to the computer, such as a printer, scanner, or external hard drive. These devices provide additional functionality to the computer and expand its capabilities beyond the basic processing and storage functions.

The technology that merges computing with high-speed communications links carrying data, sound, and video is information technology. This term refers to the use of computers and telecommunications systems to store, retrieve, transmit, and manipulate data. With the advancement of technology, information can now be easily accessed and shared through various communication channels, making information technology an essential part of our modern world.
