c) Hardware components of a computer
include:
1. Central Processing Unit (CPU): The
CPU is the brain of the computer, responsible for executing instructions and
performing calculations.
2. Random Access Memory (RAM): RAM
is volatile memory used to temporarily store data and program instructions that
the CPU needs to access quickly.
3. Storage Devices:
Storage devices, such as hard disk drives (HDDs) and solid-state drives (SSDs),
are used to store data and programs permanently.
4. Motherboard: The
motherboard is the main circuit board that houses the CPU, RAM, storage
devices, and other essential components. It provides the electrical connections
between these components.
5. Input/Output (I/O) Devices: I/O
devices allow users to interact with the computer and exchange data. Examples
include keyboards, mice, monitors, printers, and network interfaces.
Explanation of five components in detail:
- CPU: The CPU executes
instructions stored in memory, performing arithmetic, logical, and control
operations. It consists of an arithmetic logic unit (ALU) for computation and
control unit (CU) for instruction decoding and execution.
- RAM: RAM provides temporary
storage for data and program instructions that the CPU needs to access quickly.
It allows for faster data retrieval compared to storage devices but is
volatile, meaning it loses its contents when the computer is powered off.
- Storage Devices:
Storage devices are used to store data and programs permanently. HDDs use
magnetic storage to store data on spinning disks, while SSDs use flash memory
for faster access speeds. Storage capacity and speed vary depending on the type
of device.
- Motherboard: The
motherboard is a printed circuit board that connects and holds various
components of the computer together. It provides interfaces for connecting CPU,
RAM, storage devices, expansion cards, and I/O devices. It also contains the
BIOS (Basic Input/Output System) firmware.
- Input/Output Devices: Input
devices allow users to input data and commands into the computer, while output
devices display information and results to the user. Keyboards and mice are
common input devices, while monitors and printers are common output devices.
Networking interfaces allow the computer to connect to other devices and
networks for communication.

b) Drum Printer vs. Chain Printer:
Drum Printer:
- Drum
printers use a cylindrical drum as the printing mechanism.
- The
drum is coated with characters or symbols in a fixed pattern around its
circumference.
- To
print a character, the drum rotates to position the desired character in
alignment with the paper.
- A
hammer or print element strikes the paper against the inked character on the
drum, transferring the character onto the paper.
- Drum
printers are relatively fast and produce high-quality output.
-
Example: IBM 1403 is a classic drum printer used in early computer systems.
Chain Printer:
-
Chain printers use a rotating chain of characters or symbols as the printing
mechanism.
- The
chain consists of interconnected characters arranged in a sequential order.
- To
print a character, the chain rotates to position the desired character in front
of the paper.
- A
hammer or print element strikes the paper against the inked character on the
chain, transferring the character onto the paper.
-
Chain printers are known for their high speed and reliability, making them
suitable for high-volume printing tasks.
-
Example: Diablo 630 is a popular chain printer used in business environments
for producing invoices, reports, and other documents.
In
summary, drum printers and chain printers differ in their printing mechanisms,
with drum printers using a cylindrical drum and chain printers using a rotating
chain of characters. While both types of printers are capable of producing
high-quality output, chain printers are typically faster and more suitable for
high-volume printing applications.

Q.5 In what respect speech synthesizer is
helpful for a user? Explain with the help of
a suitable example.
A
speech synthesizer, also known as a text-to-speech (TTS) system, is a
technology that converts written text into spoken words. It has several
benefits for users, particularly those who may have difficulty reading or
accessing written information. Here's how a speech synthesizer can be helpful
for a user:
1. Accessibility:
Speech synthesizers enhance accessibility for individuals with visual
impairments or learning disabilities, as well as those who may have difficulty
reading due to language barriers or cognitive challenges. By converting written
text into spoken words, speech synthesizers enable these users to access and
understand information more effectively.
2. Independence:
Speech synthesizers empower users to access written content independently,
without relying on assistance from others to read aloud or interpret text. This
promotes autonomy and self-reliance, allowing users to engage with digital
content, such as websites, documents, and emails, on their own terms.
3. Multitasking: Speech
synthesizers enable users to consume written content while engaging in other
activities, such as cooking, exercising, or commuting. By listening to spoken
words, users can multitask more efficiently and make better use of their time
without being tied to a screen or printed material.
4. Customization:
Speech synthesizers often offer options for customization, allowing users to
adjust settings such as speech rate, pitch, and volume to suit their
preferences and needs. This flexibility ensures a personalized and comfortable
listening experience for each user.
5. Pronunciation Assistance: Speech
synthesizers can assist users in learning how to pronounce unfamiliar words or
phrases correctly. By hearing the correct pronunciation spoken aloud, users can
improve their language skills and expand their vocabulary more effectively.
Example:
Consider
a visually impaired student who needs to study a textbook for an upcoming exam.
Instead of relying solely on printed material or assistance from others, the
student can use a speech synthesizer application on their computer or mobile
device to convert the text into spoken words. By listening to the content
through headphones or speakers, the student can absorb the information more
efficiently, take notes, and review the material as needed. This enables the
student to study independently, access the same educational resources as their
peers, and succeed academically without barriers imposed by visual impairment.
