10 Questions
Which one of these best describes an operating system (OS)?
A software that manages memory and provides an interface between hardware and software.
What is the main difference between firmware and an operating system (OS)?
Firmware is developed specifically for a hardware, while an OS is developed for multiple hardware.
What is the role of an operating system (OS)?
To manage memory, provide an abstraction of the hardware, and act as an intermediary between programmers/users and hardware.
What is fragmentation in the context of memory management?
When memory is allocated and then freed, leaving empty spaces between occupied spaces.
How does fragmentation affect storage?
Fragmentation can cause storage to not be in sequential order, as some of the empty spaces are given to new processes.
Which of the following is a benefit of learning about OS basics?
Increased performance in applications
What is the relationship between hardware, OS, application programs, and users?
Hardware → OS → Application Programs → User
What is the main function of an operating system (OS)?
Provides hardware abstraction and resource management
What is the kernel in an operating system (OS)?
The program that runs all the time on the computer
Which of the following is not a role of an operating system (OS)?
Application development
Study Notes
Operating System (OS) Basics
- An Operating System (OS) is a set of software that manages computer hardware resources and provides common services to computer programs.
Firmware vs Operating System (OS)
- The main difference between firmware and an operating system (OS) is that firmware is a type of software that is permanently stored in the read-only memory (ROM) of a hardware device, whereas an OS is a set of software that manages computer hardware resources.
Role of an Operating System (OS)
- The role of an operating system (OS) is to manage computer hardware resources, provide common services to computer programs, and act as an intermediary between computer hardware and user-level applications.
Fragmentation in Memory Management
- Fragmentation in the context of memory management refers to the phenomenon where free memory is broken into small, non-contiguous blocks, making it difficult to allocate memory for large requests.
Effects of Fragmentation on Storage
- Fragmentation can lead to reduced storage capacity, slower storage access, and increased storage fragmentation, making it essential to implement memory management techniques to mitigate these effects.
Benefits of Learning OS Basics
- Learning about OS basics can help individuals develop problem-solving skills, understand how computers work, and make informed decisions when choosing computer hardware and software.
Hardware, OS, Application Programs, and Users
- The relationship between hardware, OS, application programs, and users is that the OS acts as an intermediary between the hardware and application programs, providing an environment for the programs to interact with the hardware and users.
Main Function of an Operating System (OS)
- The main function of an operating system (OS) is to manage computer hardware resources, allocate system resources, and provide common services to computer programs.
Kernel in an Operating System (OS)
- The kernel is the central part of an operating system (OS) that manages hardware resources, provides services to application programs, and acts as a bridge between hardware and software.
Role of an Operating System (OS) Exception
- An operating system (OS) is not responsible for writing application programs or providing content for user interfaces.
