UNIT I (FIRST HALF)

What is the function of a CPU in a computer?

• Displays images on a screen

• Stores data in a computer

• Manages internet connections

• Executes instructions and performs calculations in a computer.

Describe the difference between RAM and ROM.

• RAM is non-volatile and used for temporary storage, while ROM is volatile and used for permanent storage.

• RAM is used for long-term storage, while ROM is used for short-term storage.

• RAM is used for read-only purposes, while ROM is used for read and write operations.

• RAM is volatile and used for temporary storage, while ROM is non-volatile and used for permanent storage.

Explain the concept of Moore's Law in the context of computer technology evolution.

• Moore's Law predicts that the number of transistors on a microchip remains constant every two years.

• Moore's Law is the observation that the number of transistors on a microchip doubles approximately every two years, resulting in increased computing power and performance.

• Moore's Law states that computer performance decreases over time due to the limitations of microchips.

• Moore's Law suggests that advancements in computer technology are unrelated to the number of transistors on a microchip.

How does hardware differ from software in a computer system?

• Hardware is temporary, while software is permanent.

• Hardware is intangible, while software is tangible.

• Hardware is responsible for processing data, while software is responsible for storing data.

• Hardware is the physical components, and software is the programs that run on the hardware.

What is the significance of the binary number system in computing?

• Binary numbers are only used in advanced computing systems.

• Computers primarily use decimal numbers for processing data.

• The binary number system is not relevant to computing.

• Binary numbers are the foundation of how computers store and process information.

Define an operating system and list its basic functions.

• The basic functions of an operating system include cooking meals

• An operating system is a software that manages computer hardware resources and provides common services for computer programs. Its basic functions include managing memory, controlling hardware devices, providing a user interface, managing files and directories, and facilitating communication between software and hardware.

• Operating systems are only used in smartphones

• An operating system is a type of hardware

What is a flow chart and how is it used in computer programming?

• A flow chart is a musical notation used to compose computer programs.

• A flow chart is a visual representation of a process or algorithm, used in computer programming for planning and communication purposes.

• A flow chart is a type of computer virus used to disrupt programming processes.

• A flow chart is a physical device used to cool down computer systems.

What are the primary components of a computer system?

• Operating system, software, printer, scanner

• GPU, RAM, keyboard, monitor

• Ethernet cable, modem, router, firewall

• CPU, memory, storage, input devices, output devices, motherboard

Discuss the importance of the hexadecimal number system in computing.

• The hexadecimal number system is important in computing because it provides a more compact way to represent binary data. It is commonly used in programming, memory addressing, and color encoding.

• Using hexadecimal numbers in computing leads to slower processing speeds.

• Hexadecimal numbers are not compatible with modern computer systems.

• The hexadecimal number system is only used for basic arithmetic operations in computing.

Describe the key features of a modern operating system.

• No file system management, lack of device driver support

• Outdated user interface, no security features

• Multitasking, virtual memory, file system management, device driver support, user interface, security features, networking capabilities, hardware and software compatibility

• Single-tasking, limited memory usage
