what is monitor?

What is a monitor?
The monitor is the piece of computer hardware that displays the video and graphics information generated by the computer through the video card.
Monitors are very similar to televisions but usually display information at a much higher resolution. Also unlike televisions, monitors are not usually mounted on a wall but instead sit atop a desk.

Other Names of a Monitor

A monitor is sometimes referred to as a screen, display, video display, video display terminal, a video display unit, or video screen.
A monitor is sometimes incorrectly referred to as the computer, as in the hardware within the computer case, like the hard drive, video card, etc. For example, shutting down the computer isn't the same thing as turning off the monitor. It's important for that distinction to be made.

Important Monitor Facts

A monitor, no matter the type, usually connects to either an HDMI, DVI, or VGA port. Other connectors include USB, DisplayPort, and Thunderbolt. Before investing in a new monitor, make sure that both devices support the same type of connection.
For example, you don't want to buy a monitor that has only an HDMI port when your computer is capable of accepting only a VGA connection. Although most video cards and monitors have multiple ports so as to work with various kinds of both devices, it's still important to check their compatibility.
f you do need to connect an older cable to a newer port (e.g., HDMI to VGA) — like if you're using a monitor that has a VGA connection, with a computer that uses HDMI — there are adapters for this very purpose.
Monitors are not typically user serviceable. For your safety, it's not usually wise to open and work on a monitor.

Explain Ups in a computer? And how ups work

# Define UPS :- An uninterruptible power supply (UPS) provides nearly instantaneous power when the main utility power source fails, allowing either time for power to return or for the user to shut down the system or equipment normally by closing running computer system applications and using the operating system to shut down the system. The user has between five and 15 minutes to shut down a system normally or bring an auxiliary power source online to restore the power supply. In addition, most UPS systems also work to address power source electrical surges, sag voltage, voltage spikes, frequency instability, noise interference or harmonic distortion from the ideal sinusoidal wave form. #Explains  :- A UPS is not limited by equipment type and ensures uninterruptible power to computers, data centers or other electrically powered equipment during an unexpected power failure. UPS units vary depending on the protected equipment size, which can range ...

What are the macanism of a speaker?

H ow many times every day do you hear recorded music on the  TV , in stores, in  elevators —even in the street? You'd never hear music at all if it weren't for  loudspeakers : electric sound-making machines. Most of the music we hear around us is played back with big loudspeakers attached to stereos or tiny earbud  headphones .  Radios ,  televisions , computers ,  cellular phones , intercoms, and talking toys are just some of the electric gadgets that make sounds with loudspeakers. But what exactly are loudspeakers and how do they work? How loudspeakers turn electricity into sound When things shake about, or vibrate, they make the sounds we can hear in the world around us. Sound is invisible most of the time, but sometimes you  can  actually see it! If you thump a kettle-drum with a stick, you can see the tight drum skin moving up and down very quickly for some time afterward—pumping sound waves into the air. Loudspeakers ...
