Live preview is available on a touch screen T/F

TEA [102]

It is false that live preview is available on a touch screen. Life preview refers to cameras mostly, and to the fact that its display screen can be used as a viewfinder. Viewfinder is what you look through when you are using a camera to take a photo, or to focus on something. So, no, touch screen devices do not have this feature available, only the "old-school" cameras do.

Explain demand paging with a proper example

julia-pushkina [17]

<h2>Demand paging :</h2>

<h3>In computer operating systems, demand paging (as opposed to anticipatory paging) is a method of virtual memory management. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it and that page is not already in memory (i.e., if a page fault occurs). It follows that a process begins execution with none of its pages in physical memory, and many page faults will occur until most of a process's working set of pages are located in physical memory. This is an example of a lazy loading technique.</h3>

REY [17]

Answer:

The old cathode Ray tube technology was replaced by the less bulkier and more modern liquid crystal display and LED technology.

The old cathode ray tube uses the principle of electrical discharge in gas. Electrons moving through the gas, and deflected by magnetic fields, strike the screen, producing images and a small amount of X-rays. The tube required more space, and consumed more electricity, and was very bulky. The modern technologies are more compact and consume less power, and can been designed to be sleek and less bulky.

Advantages:

The auto negotiation protocol features used to maximize the throughput of data link layer.
This protocol are basically useful in the local area network (LAN), with multiple capability of connections.
The auto negotiation protocol extremely useful in twisted pair which are based on ethernet.

Disadvantages:
