Explanation:
Kindly check the attached images below to the see the step by step explanation to the question above.
In a polling-based network receives, the operating system keeps checking the status register after a fixed time interval to see whether a device needs hardware attention or not. CPU gradually checks the status of receive bit after a defined time interval of a clock and if the value of receive bit is true then data is moved from the RX register to the memory. In interrupt-based networks, whenever a device needs hardware processing then an interrupt is raised to inform the CPU for device attention. The data of the device is transferred to memory from the network card.
Polling is a protocol, not a hardware mechanism where the device gets attention by CPU. An interrupt is a hardware mechanism, not a protocol where the device gets attention by the interrupt handler. In polling, during receiving, parts of received data need to transfer to memory but in case of interrupts, whole data is transferred at once after receiving is done. An interrupt is a heavy operation as compared to pooling because hardware involves in it. For large amounts of data, Polling becomes an inefficient method. In polling, CPU gradually checks devices at regular intervals whereas the Interrupt handler can send interrupt at any time. Each device has its own Command ready bit which indicates whether the device requires servicing or not. In polling, CPU wastes numerous clock cycles by repetitively checking the command-ready little bit of each device. In Interrupt based network, the interrupt request line indicates whether the device requires servicing or not. In interrupt-based network, CPU cycles not wasted but CPU is disturbed only when device send interrupt signals.
Relative performance between programmed I/O and DMA:
For determining the relative performance between programmed I/O and DMA, important factors are:
1. Size of data
2. Frequency of operations
I think those 9 tasks would be :
1. learns windows powershell
2. Plow through licensing
3. focus on strategic improvements
4. Expand the deployment scope
5. Prepare for distributed security
6. Virtualize your destkop
7. Evaluate enterprise features
8. Build compatibility safety nets
9. Remove your users' local admin rights
To create a song of the Summer edhesive you can use the Python Code,
which will help you create sections based on the music genre.
<h3 /><h3>What is Python code?</h3>
It corresponds to a programming language that enables the development of various media platforms, such as games, social networks and artificial intelligence applications.
Therefore, the Python code helps to automate tasks as it is an open-source language, allowing communication and adaptation of different objectives.

Explanation:
Tablets are more portable than any computer or laptop. They are very lightweight and can fit in a purse or small bag with relative ease. They are designed to be taken everywhere with you, thus the very definition of portable.
Storage Computer hard drives can be over one TB (terabyte). Even the most basic computer comes with a 250 GB (gigabyte) hard drive, which for many is more than enough storage for most users. Tablets come with built-in storage ranging from 8 GB to 128 GB. In some cases, an expansion slot may be available for adding additional storage.
Battery life The battery life even for the most efficient laptop is still not close to the battery life of a tablet. A tablet has a much smaller screen and has fewer components than a laptop computer, which makes for a longer battery life.
Operating System Desktop and laptop computers come with more fully featured operating system due to having the computing power and memory requirements. These operating systems support more than any tablet operating system. Tablets come with a more slimmed down operating system because of the limited computing power and memory. The Android OS and Apple iOS are adequate operating systems for tablet users, but not as complete as computer operating systems.
Boot time The latest computers running the latest operating systems have improved a lot on their boot time. However, are still slower than a tablet. Generally speaking, most tablets are much faster at booting than most computers.
Data entry and user input A computer uses a keyboard for data entry that most users are familiar with and comfortable using. The mouse is also available for easy scrolling and right-clicking. Tablets use an on-screen keyboard that is smaller than a standard computer keyboard, takes time to learn, and users with bigger fingers may have a hard time typing. Some tablets allow for an external keyboard, providing a more comfortable and familiar medium for typing.
Touch screen Although some laptops and desktops now support touch, most still have no touch screen support. All tablets support a touch screen, that's easier for new computer.
