Yes, that is correct. DVDs typically have more storage capacity than CDs.

A standard CD can hold up to 700 MB of data, while a single-layer DVD can hold up to 4.7 GB of data. Dual-layer DVDs can hold up to 8.5 GB of data. This increased storage capacity allows for higher-quality video and audio, as well as more data storage for computer files.

The increased storage capacity of DVDs is due to their use of smaller pits and lands on the disc surface, as well as their ability to store data on multiple layers within the disc. These factors enable DVDs to hold more data than CDs.

Tally is a popular accounting software that is widely used in businesses and organizations to manage their financial transactions and accounting processes. It is a comprehensive software package that offers features such as accounting, inventory management, payroll processing, taxation, and financial reporting.

Fourth Generation (1970s-1990s):VLSI (Very Large Scale Integration) is a technology used in the design and manufacture of microchips or integrated circuits. It involves the integration of millions of transistors, resistors, capacitors, and other electronic components on a single chip.

The fourth generation of computers introduced microprocessors, which are ICs that contain a complete CPU on a single chip. They also introduced the use of personal computers (PCs) and graphical user interfaces (GUIs). Examples include Apple II and IBM PC.

A computer interprets and executes a set of instructions known as a program. A program is a set of instructions written in a computer language that tells the computer what to do. The computer's central processing unit (CPU) is responsible for executing these instructions.

The CPU is the "brain" of the computer and is responsible for performing arithmetic and logical operations, as well as controlling the flow of data between the computer's various components. When a program is executed, the CPU retrieves the instructions from memory and executes them one by one, following the program's logic and carrying out the required computations.

The process of interpreting and executing a program is known as "running" or "executing" the program. During this process, the CPU interacts with other components of the computer, such as the memory and input/output devices, to carry out the program's instructions and produce the desired output.

A program consists of a set of instructions that tell a computer what to do. These instructions are written in a computer language that the computer can understand, such as C++, Python, Java, or JavaScript.

A software package or application suite consists of a set of programs designed to work together to perform a specific set of tasks or provide a specific set of features. These programs may be written in different programming languages and may have different functionalities, but they are all integrated into a single package that is distributed and installed as a single entity.

Paint Brush is not a text editor, it is a basic graphics editing program that allows users to create and modify images using a variety of tools such as brushes, shapes, and color palettes.

A text editor, on the other hand, is a program used to create and edit plain text files. Text editors are used to write code, scripts, or other types of documents that do not require advanced formatting or layout options.

Examples of text editors include Notepad, Sublime Text, Vim, and Emacs. These programs allow users to enter and edit text, save files in different formats, and perform basic search and replace operations.

• A keyboard converts the characters typed by the user into machine-readable code, specifically ASCII (American Standard Code for Information Interchange) code.
• Each character on the keyboard is assigned a unique ASCII code, which is a numerical representation of the character. For example, the letter "A" is assigned the ASCII code 65, while the number "1" is assigned the ASCII code 49.
• When a user types a character on the keyboard, the keyboard sends an electrical signal to the computer that corresponds to the ASCII code for that character. The computer then uses this code to display the character on the screen, save it to a file, or perform other operations as needed.
• Overall, the keyboard plays a crucial role in converting the user's input into machine-readable code, which the computer can process and use to perform various tasks.

• The Control Unit (CU) controls the operation of the CPU (Central Processing Unit) in a computer.
• The CU is responsible for retrieving instructions from memory, interpreting them, and directing the operations of the other components of the CPU to carry out those instructions. It also manages the flow of data between the CPU and other components of the computer, such as the memory and input/output devices.
