1.What is a proprietary os for desktop and laptop computers?

Operating system (OS) is a computer program that manages and controls computer hardware and software resources. It is the most basic system software that runs directly on "bare metal", and a collection of system software that controls the operation of other programs and provides users with an interactive operating interface. Any other software must be supported by the operating system to run. What are the proprietary operating systems for laptops and desktops? The answer is windows. All versions of the operating system that Microsoft releases have never been divided between laptops and desktops.

Why does a laptop-specific operating system appear? This is because the hardware configuration of a laptop is slightly different from that of a desktop computer. For example, some laptop shortcut keys and other function keys cannot be used without drivers. After installing the operating system, if you want to use these functions, To install these drivers again, some system producers add notebook-specific drivers to the Microsoft operating system for the convenience of users, which forms an operating system specially used for notebooks.

Because the laptop-specific operating system has more drivers than ordinary operating systems, it can be used for desktop computers, but some laptops are not very good for desktop systems because of the lack of drivers required for laptops.

The main functions of the operating system

  • Processor management

  • The most basic function of processor management is to handle interrupt events. The processor can only detect interrupt events and generate interrupts but not process them. Once the operating system is configured, various events can be processed. Another function of processor management is processor scheduling. There may be one or more processors, and different types of operating systems will adopt different scheduling strategies for different situations. Also called process management.
  • Memory management

  • Memory management mainly refers to the management of internal memory. The main task is to allocate memory space, ensure that the storage space occupied by each job does not conflict, and make sure that each job does not interfere with each other in its own storage area.
  • Device management

  • Device management refers to the management of various peripheral devices (referred to as: peripherals), including allocation, startup, and troubleshooting. The main task is: when the user uses the external device, he must put forward a request, and it can be used after the operating system is uniformly allocated. When the user's program runs to use a peripheral device, the operating system is responsible for driving the peripheral device. The operating system also has the ability to handle peripheral interrupt requests.
  • File management

  • File management refers to the management of information resources by the operating system. In an operating system, a portion of management information responsible for access is called a file system. A file is an ordered collection of a logically complete set of related information, each with a filename. File management supports operations such as file storage, retrieval, and modification, as well as file protection functions. Operating systems generally provide file systems with strong functions, and some also provide database systems to manage information.
  • Job management

  • A separate operation that each user requests the computer system to perform is called a job. Job management includes job input and output, job scheduling and control (controlling job running steps according to user needs).

2.How to get sound from laptop to tv with hdmi?

How do i get sound play from my laptop pc to my tv with hdmi? Please follow the steps below:

  1. Connect one end of the data cable (VGA or HDMI) into the computer and the other end into the corresponding interface of the TV.
  2. The computer is powered on and turned on, and the television is powered on and turned on.
  3. Use the remote control board to select the signal source VGA or HDMI (selected according to the data cable) on the TV.
  4. Press WIN+P on the computer.
  5. Select Projection or Copy in the pop-up dialog box. (Projection is to display the picture only on the TV, and duplication is to display the picture on both the TV and the TV).
  6. After the screen appears on the TV, use the mouse to adjust the resolution of the computer to the resolution suitable for the desktop monitor.

Tip: You can output audio and video from computer to tv though HDMI cable, and the picture and sound can be displayed on the TV. If the VGA cable is used, only the screen will be displayed on the TV, and another speaker needs to be connected to the computer.

Computer connected to HDMI device no sound solution

In some cases, hdmi audio will not work, and sound not playing or going to tv through hdmi, there are 3 solutions listed below
  • Method 1. Check if all hardware devices are working properly

  • Damaged hardware devices may prevent HDMI from working properly. So, before using other solutions, check that all hardware devices are working properly:
    1. Check the cables for problems. Use another cable to see if the problem is resolved.
    2. Check if the output port is working properly. If your PC has multiple HDMI output ports, try different ports to see if the problem is solved.
    3. Check if the monitor is working properly. Make sure the monitor's speaker volume is not turned down or muted. Then try connecting the monitor to another PC.
  • Method 2:

  • Taking Win7 as an example, first we right-click the icon of "Small Speaker" in the lower right corner of the desktop, the menu bar will pop up, and click "Playback Device (P)", as shown in the following figure; At this time, we enter the sound panel. At this time, we right-click on the digital output device (HDMI) and "set as default device" to solve the problem of no sound when connected to HDMI, as shown in the following figure:

  • Method 3:

  • We right-click "Computer" on the desktop, select Device Manager, and find the "Sound, Video and Game Controller" item in the Device Manager. We only need to shield the sound card that comes with the system's default motherboard, usually "AMD High Definition Audio" and "High Definition Audio", etc., only use the sound card channel in the graphics card.
