Data is stored in computers in binary form. Binary is a base-2 number system that uses only two digits, 0 and 1, to represent all possible values. In computers, data is stored and processed using electronic circuits that can represent these two states, on and off, which correspond to 0 and 1 in binary. This binary representation allows computers to perform calculations and manipulate data efficiently using logic gates and binary arithmetic operations. Other number systems like decimal, hexadecimal, and octal are often used for human-readable representation or for specific purposes, but the underlying storage and processing in computers is based on binary.

A computer with more than one processor is known as a multiprocessor. This means that the computer has multiple CPUs (central processing units) working together to execute tasks and process data simultaneously. Having multiple processors allows for increased performance and the ability to handle multiple tasks or processes simultaneously.

The correct answer is World Wide Web. The term "WWW" refers to the World Wide Web, which is a system of interconnected documents and resources accessed through the internet. It was created by Tim Berners-Lee in 1989 and has since become a fundamental part of the internet, allowing users to navigate and access information from various websites using hyperlinks.

RAM (Random Access Memory) is a type of computer memory that is used to store data that is being actively used by the computer. It is a volatile memory, meaning it requires a constant supply of power to retain the stored data. RAM is typically located on the motherboard of a computer. It is directly connected to the CPU (Central Processing Unit) and allows for fast access to data, which helps in improving the overall performance of the computer. Therefore, the correct answer is Mother Board.

The components of a Central Processing Unit (CPU) are responsible for executing instructions and performing calculations. The Arithmetic Logic Unit (ALU) is responsible for performing arithmetic and logical operations, while the Control Unit (CU) is responsible for coordinating and controlling the activities of the CPU. Therefore, the correct answer is Arithmetic logic unit, Control unit.

The first generation of computers had vacuum tubes and magnetic drums as their primary components. Vacuum tubes were used as electronic switches to perform calculations, while magnetic drums were used for data storage. These computers were large, expensive, and consumed a lot of power. They were also prone to frequent breakdowns and required constant maintenance. However, they laid the foundation for future advancements in computer technology.

A URL is the address used to access resources on the internet. It specifies the protocol to be used, such as HTTP or FTP, followed by the domain name or IP address of the server, and the specific path to the resource. The correct answer, Uniform Resource Locator, accurately describes the full form of URL. It is a standardized way of identifying and locating resources on the web.

A computer that provides database services to others is known as a database server. This type of server is specifically designed to store, manage, and retrieve data from a database. It allows multiple users to access and manipulate the data simultaneously, ensuring data integrity and security. It typically runs database management software and provides functionalities like data storage, data backup, data recovery, and query processing.

DSL stands for Digital Subscriber Line, which is a technology used to provide internet by transmitting data over the wires of the telephone network. DSL allows for high-speed internet access by utilizing existing telephone lines without interfering with voice calls. It works by separating the voice and data signals, allowing simultaneous use of the telephone line for both internet and telephone services. DSL is a common and widely used technology for residential and small business internet connections.

Assembly Language is considered a low-level programming language because it is closer to machine language than high-level languages. It uses mnemonic codes and symbols to represent the machine instructions, making it easier for programmers to understand and write code that directly interacts with the hardware. However, it is still more human-readable and easier to work with than machine language, which consists of binary instructions.
