It is not written in point form, making it difficult both for your audience to read and for you to present each point. Although there are exactly the same number of points on this slide a...

DMA IN MP

-
  What is DMA and Why it is used? Direct memory access (DMA) is a mode of data transfer between the memory and I/O devices. This happens without the involvement of the processor. We have two other methods of data transfer, programmed I/O and Interrupt driven I/O. Let’s revise each and get acknowledge with their drawbacks. In programmed I/O, the processor keeps on scanning whether any device is ready for data transfer. If an I/O device is ready, the processor fully dedicates itself in transferring the data between I/O and memory. It transfers data at a high rate, but it can’t get involved in any other activity during data transfer. This is the major drawback of programmed I/O. In Interrupt driven I/O, whenever the device is ready for data transfer, then it raises an interrupt to processor. Processor completes executing its ongoing instruction and saves its current state. It then switches to data transfer which causes a delay. Here, the processor doesn’t keep scanning for periphe...

AUTOMATA DEFINITIONS

-
 AUTOMATA DEFINITIONS THIS SUBJECT IS FULLY BASED ON EXAMPLES, DEFINITIONS, GRAMMAR RULES, DIAGRAMS AND THEOREMS. IMPORTANT DEFINITIONS:  DFA:    A Deterministic Finite State Automaton (DFSA) is denoted by M and it is a set of 5-tuples i.e. M=(Q, Σ, δ, q 0 , F) where, * Q is a non-empty finite set of states * Σ is a non-empty finite set of input symbols *  q 0 is the initial state or starting state. (q0 ∈ Q) * F is a non-empty finite set of final state. (F ⊆ Q). * δ (pronounce delta) is the transition function. Q x Σ → Q. δ(q,a) = p means, if  the automation is in state q and reading a symbol a, it goes to state p in the next instant, moving the pointer one cell to the right. NDFA:    A Non-Deterministic Finite State Automaton (NFSA) is denoted by M and it is a set of 5-tuples i.e. M=(Q, Σ, δ, q 0 , F) where, * Q is a non-empty finite set of states * Σ is a non-empty finite set ...

how to use vim editor in gitbash

-
 Using the Vim editor in Git Bash is similar to using it in any terminal environment. Vim is a powerful text editor available on most Unix-based systems, including the Git Bash environment on Windows. Here’s a basic guide on how to use Vim within Git Bash: ### 1. **Opening Vim**    - To open a file in Vim, navigate to the directory containing your file using Git Bash and type:      ```bash      vim filename      ```      Replace `filename` with the name of the file you want to edit. If the file doesn’t exist, Vim will create it when you save. ### 2. **Basic Vim Modes**    - **Normal Mode:** This is the default mode when you open Vim. In this mode, you can navigate through the file and issue commands.    - **Insert Mode:** This mode allows you to insert text into the file. To enter Insert Mode from Normal Mode, press `i`.    - **Command Mode:** This mode is used for saving, quitting, ...

 Sure, let's cover how to use Laravel sessions to store success and error messages and display them in Blade templates, as well as how to store the user ID in the session.            // Store the authenticated user's ID in the session...            session(['user_id' => Auth::id()]);            // Retrieve the user ID from the session...            $userId = session('user_id');  Step 2: Using Sessions for Success and Error Messages # Instructions: 1. Setting Up Controller Methods with Success/Error Messages:    In your `BookController`, add session flash messages in the store, update, and destroy methods:    ```php    namespace App\Http\Controllers;    use App\Models\Book;    use Illuminate\Http\Request;    class BookController extends Controller    {        public fu...

Java Interview Questions

-
  Java Interview Questions 1. What are the differences between C++ and Java? C++ is not platform-independent; the principle behind C++ programming is “write once, compile anywhere.” In contrast, because the byte code generated by the Java compiler is platform-independent, it can run on any machine, Java programs are written once and run everywhere. ·         Languages Compatibility. C++ is a programming language that is based on the C programming language . Most other high-level languages are compatible with C++. Most of the languages of Java are incompatible. Java is comparable to those of C and C++. ·         Interaction with the library. It can access the native system libraries directly in C++. As a result, it’s better for programming at the system level. Java’s native libraries do not provide direct call support. You can use Java Native Interface or access the libraries. ·         Characteristics. C++ distinguishes it...

OPERATING SYSTEM MCQ

-
  Which of the following is an example of a spooled device? a. A line printer used to print the output of a number of jobs. b. The terminal used to enter the input data for a Fortran program being executed. c. The secondary memory device in a virtual memory system. d. The swapping area on a disk used by the swapper. In spooling (Simultaneous Peripheral Operation On Line), a buffer is interposed between a running program and a slow-speed device involved with the program for input/output. For example, instead of writing lines directly to the line printer, the lines are written (temporarily) onto a disk. Thus, the program is allowed to run to completion without waiting for the (slow) printer to finish. When the printer becomes free, the lines can be printed from the disk file. 2. Which of the following is not normally contained in the directory entry of a file? a. Creation date. b. Access control list. c. A count of the number of free blocks in the disk. d. Filename an...
