Computer Science and Linux System Questions

What does the term 'blocking' refer to in the context of I/O software?

• A. A technique for managing device drivers.

• B. A mechanism for ensuring devices are synchronized.

• C. The process of stopping a process until an I/O operation is completed.

• D. A method of allocating memory for I/O operations.

___ includes every peripheral unit in the system such as disks, clocks, keyboards, displays, and so on.

• I/O devices

• Memory

• CPU

• Software

What is the purpose of Direct Memory Access (DMA) in I/O hardware?

• To manage parallel data transfers.

• To allocate memory for device drivers.

• To enable devices to transfer data to and from memory without CPU intervention.

• To provide data interfaces for I/O devices.

Regarding the computer's interrupt, which of the following is the number on the address lines that is used as an address to select a fetch in an interrupt controller?

• Interrupt handler

• Interrupt pointer

• Interrupt executor

• Interrupt vector

What addresses are typically used by most DMA controllers for transmission?

• Logical memory

• Allocated memory

• Virtual memory

• Physical memory

In Linux, what is the primary purpose of the /etc directory?

• To store temporary files.

• To manage system boot files.

• To store system configuration files and scripts.

• To store user home directories.

When the computer is booted, what is used to read in and execute?

File sharing: In Unix, to copy one of C's files by issuing the system creates a new file of type LINK and entering that file name in the directory. The new file has the same index number as the original file, and any changes made to either file are reflected in both. This is called file sharing. File sharing is a type of file linking. In symbolic linking, the system creates a new file that contains the name of the file being linked to, not its index number. In traditional (hard) linking, the system creates a new file entry with the same index number as the original file. Which of the following is the correct about the type of file sharing described above?

• Symbolic Linking

• Symphonic Linking

• Traditional (hard) Linking

• Synthetic Linking

What is fragmentation in the context of file system implementation?

• A. A technique for managing directory structure.

• B. The allocation of memory for file storage.

• C. The splitting of free file space into smaller, non-contiguous blocks.

• D. The arrangement of files on storage devices.

When a directory has been read, it should be closed to free up internal table space that is ___

• Cleaned

• Cleared

• Dynamic

• Opened
