Interaction Between Software and Hardware

How does a printer receive instructions from a computer to print a document?

• The printer receives instructions from the computer via telepathy

• The printer interacts with the computer through device drivers.

• The interaction between the printer and computer is purely physical

• The computer interacts with the printer through virtual reality

Describe the different types of networks and their characteristics.

• PAN, CAN, and DAN are the main types of networks with different characteristics based on their geographical coverage.

• LAN, WAN, and FAN are the main types of networks with different characteristics based on their geographical coverage.

• LAN, WAN, and MAN are the main types of networks with different characteristics based on their geographical coverage.

• VPN, SAN, and NAN are the main types of networks with different characteristics based on their geographical coverage.

How does a computer's operating system (software) communicate with its physical components (hardware)?

• Through interpretive dance routines

• By using carrier pigeons

• Through a series of instructions where the operating system sends commands to the computer's physical components for execution.

• Through telepathic communication

What are the unique characteristics of different types of networks?

• Voltage, current, resistance, power

• Operating system, manufacturer, price, warranty

• Topology, transmission media, communication protocols, scalability, security features, speed

• Color, size, weight, shape

Outline the various types of networks and their respective features.

• MAN: Limited geographical area, low data transfer rates, typically used within a single building or campus.

• PAN: Public network for connecting devices like smartphones, laptops, and tablets.

• WLAN: Covers large geographical areas, requires physical cables for connection.

• LAN: Limited geographical area, high data transfer rates, typically used within a single building or campus. WAN: Covers large geographical areas, lower data transfer rates compared to LAN, connects multiple LANs. MAN: Covers a city or large campus area, higher data transfer rates than WAN. WLAN: Wireless network, allows devices to connect without physical cables. PAN: Personal network for connecting devices like smartphones, laptops, and tablets. VPN: Secure network that allows remote access over the internet.

Consider a scenario where you are using a computer to create a digital painting. Discuss the relationship between the software (like Adobe Photoshop) and the hardware (like your computer and graphics tablet).

• Hardware is responsible for writing code

• Software provides the instructions and programs for hardware to execute tasks, such as processing your brush strokes, while hardware provides the physical components like CPU and graphics tablet for software to operate.

• Software is only used for gaming purposes

• Hardware is not necessary for software to function

List the characteristics of a LAN (Local Area Network).

• Extensive geographic area, low data transfer rates, high error rates, multiple organization ownership

• Limited geographic area, low data transfer rates, high error rates, single organization ownership

• Extensive geographic area, high data transfer rates, low error rates, single organization ownership

• Limited geographic area, high data transfer rates, low error rates, single organization ownership

Explain the concept of a WAN (Wide Area Network) and its key features.

• A WAN (Wide Area Network) is a network that covers a broad area, often connecting multiple LANs (Local Area Networks) across long distances. Its key features include high-speed data transfer, extensive geographic coverage, and the use of public or private communication lines.

• Key features of a WAN include slow data transfer speeds and limited geographic coverage.

• WANs primarily use private communication lines for data transfer.

• A WAN is a network that covers a small area and connects only a few devices.

What are the main differences between a LAN and a WAN?

• LAN and WAN are the same type of network

• LAN is a small network covering a limited area, while WAN is a large network covering a wide area.

• LAN covers a wider area than WAN

• LAN and WAN have the same speed and performance

Describe the characteristics of a MAN (Metropolitan Area Network).

• A MAN covers a larger geographic area than a LAN but smaller than a WAN, typically spanning a city or a large campus. MANs are usually operated at a single organization or by a service provider.

• MANs are typically operated by multiple organizations

• MANs are only used for personal home networks

• A MAN covers a smaller geographic area than a LAN
