How would you explain the "kernel" of a standard computer operating system in one word?
Which statement is valid regarding operating systems? Select the correct response: Operating systems are exclusively constructed to effectively develop application binary interfaces. The OS provides a convenient interface for using a particular system. In an operating system, the secondary memory and the /0 devices are managed by the ABI. An operating system is composed of instructions executed by the ISA.
Which two elements of an operating system are considered to be the most crucial ones?
When creating Linux, why did its creators choose with a kernel that doesn't allow for preemptive multitasking? In a single-processor system, why would you want to use a non-preemptible kernel? But why does employing a system with several processors reduce the value?
When creating Linux, why did its creators choose with a kernel that doesn't allow for preemptive multitasking?If there is just one processor in use, why would you want to use a non-preemptible kernel? If utilizing a system with several processors is so beneficial, then why does it decrease in value?
After an interrupt service process, how does an application resume?
How would you describe in one phrase the "kernel" of a standard operating system?
The original Linux developers built a non-preemptible kernel for unknown reasons.In a setup with just one CPU, what good does a non-preemptible kernel do? However, with a system with several processors, why does this benefit decrease?
Do not use AI.
"Interrupt" and "Traps" are two ways to halt the execution of a process.Give instances of Interrupt and Trap and the differences between them.
Consider a gadget (either a mobile phone, tablet, or a laptop) that you personally own and use. First, state the name of the gadget and describe some of its major features and the reason why you chose this gadget. Then perform a mini review of this gadget by giving your positive and negative comments on the following: (1) Visual design (2) Interactivity (3) Organization and ease of use of the different controls (buttons, screen size, position of the different ports i.e. audio output, charging port, etc). (4) Others (i.e. batter power, charging time, etc).
There are "kernel components" contained in the kernel of a conventional operating system. Depict them.
