5. Graphics Processing Unit (GPU): The GPU, also known as the graphics card, is responsible for rendering images and videos on the computer’s display. It is especially important for tasks that require graphics-intensive processing, such as gaming and video editing.
These hardware components work together to form a functional computer system, enabling various applications and tasks to be performed efficiently.
Q.3 a) Discuss the Purpose of Speech Recognition Device
Speech recognition devices, also known as speech-to-text technology or voice recognition software, are designed to convert spoken language into written text. The main purpose of these devices is to provide an alternative input method for users who may have difficulty typing or to enhance the user experience by enabling hands-free operation. The key purposes of speech recognition devices include:
- Accessibility: Speech recognition devices are essential for individuals with physical disabilities, such as motor impairments or conditions that restrict their ability to type. It allows them to interact with computers, smartphones, and other devices using their voice, thus providing an accessible means of communication and interaction.
- Increased Productivity: Speech recognition technology can significantly boost productivity by enabling faster and more efficient data entry. Users can dictate emails, documents, notes, and other text-based content, saving time compared to manual typing.
- Hands-Free Operation: In situations where using hands for typing is not practical or safe, such as driving or operating machinery, speech recognition devices offer a hands-free alternative for accessing information and performing tasks.
- Multilingual Support: Advanced speech recognition systems often support multiple languages, making it easier for users to interact with devices in their preferred language.
- Assistive Technology: Speech recognition devices serve as assistive technology for individuals with learning disabilities, dyslexia, or visual impairments, allowing them to engage in reading and writing tasks effectively.
- Medical and Legal Transcription: In medical and legal professions, speech recognition is widely used for transcribing audio recordings, saving time and effort for professionals.
- Voice Commands: Some devices use speech recognition for voice commands, enabling users to control devices and execute various functions through verbal instructions.
b) Clearly Differentiate between Drum Printer and Chain Printer? Discuss with Proper Examples.
Drum Printer: A drum printer is an impact printing device used in early computers and data processing systems. It consists of a rotating drum with characters engraved on its surface. To print, the drum rotates and aligns the desired character with the paper.
A hammer strikes the paper through an inked ribbon onto the character on the drum, leaving an impression on the paper. The drum rotates to the next character, and the process continues until the entire line is printed. Drum printers are relatively slower and less flexible compared to modern printers, and they were commonly used in early mainframe computers.
Chain Printer: A chain printer is another type of impact printer used in early computer systems. It employs a rotating chain with character pins or hammers. The chain contains a set of characters arranged in a circular fashion.
When a character is aligned with the paper, a hammer strikes the paper through an inked ribbon, producing the desired character. Chain printers are faster than drum printers and were popular for high-speed printing applications.
In summary, drum printers and chain printers are both impact printers that use hammers to create characters on paper. The key difference lies in their mechanism – drum printers use a rotating drum with characters, while chain printers use a rotating chain with character pins.
Q.4 Internet is a Well-Known Example of ICT. How Does It Enable People to Communicate Easily Through Different Communication Mediums?

Q.5 In What Respect Is a Speech Synthesizer Helpful for a User? Explain with the Help of a Suitable Example.
A speech synthesizer, also known as a text-to-speech (TTS) system, converts written text into spoken words. It is a valuable tool for users in various situations:
1. Accessibility: For individuals with visual impairments or reading difficulties, a speech synthesizer helps access written content in an auditory format, making it more accessible and enabling them to consume information independently.
Example: Consider a visually impaired student studying an e-book. By using a speech synthesizer, the student can listen to the content instead of relying on traditional visual reading methods, enhancing their learning experience.
2. Hands-Free Communication: In situations where manual interaction with devices is not feasible or safe, a speech synthesizer allows users to receive information or perform tasks through spoken commands.
Example: A driver using a GPS navigation system can rely on a speech synthesizer to receive turn-by-turn directions without taking their eyes off the road, ensuring safer driving.
3. Multilingual Support: Speech synthesizers with multilingual capabilities enable users to listen to content in different languages, bridging communication gaps and promoting inclusivity.
Example: A language learner can utilize a speech synthesizer to practice pronunciation and comprehension of foreign language texts, aiding in language acquisition.
4. Personalization: Some speech synthesizers allow users to choose from various voices, accents, and speaking styles, offering a personalized experience.
Example: A user can select a preferred voice type (male, female, etc.) and adjust the speaking rate to suit their preferences, making the listening experience more enjoyable.
5. Enhancing User Interfaces: Speech synthesizers can enhance user interfaces in applications and devices, making interactions more intuitive and user-friendly.
Example: A virtual assistant on a smartphone, like Siri or Google Assistant, utilizes a speech synthesizer to respond to user queries, providing natural and human-like interactions
