1. FUSE Documentation
   Userspace filesystem is a filesystem in which data and metadata are provided by an ordinary userspace process. The filesystem can be accessed normally through the kernel interface. Follow the link to read more about FUSE.

2. What is a User Account?
   A user account is a collection of settings and information that tells Windows which files and folders you can access, what you can do on your computer, what are your preferences, and what network resources you can access when connected to a network.

3. Virtual filesystems in Linux
   Virtual filesystems are the magic abstraction that makes the “everything is a file” philosophy of Linux possible.

1. Brief of Address Binding
   Address binding helps allocate a physical memory location to a logical pointer by associating a physical address to the logical address or the virtual address.

2. Difference between Compile Time and Load Time address Binding
   Penjelasan terkait perbedaan antara address binding tipe compile time dengan load time.

3. Address space
   The range of virtual addresses that the operating system assigns to a user or separately running program is called an address space. This is the area of contiguous virtual addresses available for executing instructions and storing data

4. Dynamic & Static Linking
   Linking is the process of bringing external programs together required by the one we write for its successful execution. Static and dynamic linking are two processes of collecting and combining multiple object files in order to create a single executable. Here we will discuss the difference between them.

5. More about Dynamic & Static Linking
   Linker is system software which plays crucial role in software development because it enables separate compilation. Instead of organizing a large application as one monolithic source file, you can decompose it into smaller, more manageable chunks that can be modified and compiled separately. When you change one of the modules, you simply recompile it and re-link the application, without recompiling the other source files.

W05

1. Page-Buffering Algorithms
   A computer can address more memory than the amount physically installed on the system. This extra memory is actually called virtual memory and it is a section of a hard disk that’s set up to emulate the computer’s RAM.

2. Allocation of Frames
   Frame allocation algorithms are used if you have multiple processes; it helps decide how many frames to allocate to each process.

3. NUMA
   Difference between Uniform Memory Access (UMA) and Non-uniform Memory Access (NUMA).

W06

1. fork() How Does it work?
   Fork system call is used for creating a new process, which is called child process, which runs concurrently with the process that makes the fork() call (parent process).

2. Parallel vs Concurrent
   Learn the difference between Parallel and Concurrent process.

3. Process vs Parent Process vs Child Process
   Learn more about process and the difference between parent and child process that can be created using fork().

1. Preemptive and non-preemptive scheduling
   Preemptive Scheduling is a scheduling method where the tasks are mostly assigned with their priorities. Sometimes it is important to run a task with a higher priority before another lower priority task, even if the lower priority task is still running.

2. Process Scheduling
   The process scheduling is the activity of the process manager that handles the removal of the running process from the CPU and the selection of another process on the basis of a particular strategy…more

3. What is RAID?
   RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives (SSDs) to protect data in the case of a drive failure.

2. Direct I/O vs Memory Mapped I/O
   Some simple explanation about the difference between direct i/o and memory mapped i/o.

3. Direct Memory Access
   Direct memory access (DMA) is a method that allows an input/output (I/O) device to send or receive data directly to or from the main memory, bypassing the CPU to speed up memory operations.
