Video Description

Scanners have the ability to take a print page and digitize it onto our computer. Today there are many types of scanners that are used in many different ways. Scanners now are multi-functional; they save images to computing systems, they email clients on a network from a centralized workstation, they are even hand-held to use like a portable mouse, for example, to scan file folder names of files being boxed and archived. Most are plug and play, some come with specific driver and program software which must be used as directed by the OEM so that your computer recognizes it. Barcode readers are able to scan barcodes, usually through USB connections and are not often used in the home. They have however, become more popular in use as a single point-of-sale tool in conjunction with card readers. KVM standards for keyboard, video, and mouse. It is used in environments where there is one display and several computer by centralizing the cabling for keyboard, video and mouse input with the use of toggling button to switch between each of the three computers that are attached to those input devices. and we'll diagram a KVM setup to demonstrate how this works.

moving on to another. One of our input devices that comes in handy, especially in office situations, is a scanner. Now our scanners are simply our devices that
00:14
allow us to take pieces of paper, taken documents that we need to scan and just place them in this into the scanner and scan the material and put it to our output. There are many different types of scanners that we see nowadays. We don't just have the
00:30
big, bulky death scanners that we have toe lay the document on top of the glass and close the screen and press scan and have it come through our computer. We have small scanners such as like meet death scanners, where it looks almost just like a small tube with an input tray and an output tray. And we just put our documents
00:49
into the input train
00:51
and it goes through our scanner and comes out of our output tray and along the way scans the document and we can we have the ability to do sometimes multiple documents, weaken, stack several papers on top and just allow them one by one to scan and then to input into our computer and form of J pegs or PDF documents, whichever type of document we wanted to out.
01:11
But as on our computer
01:11
now, these scanners typically come with additional software that we need to add into our computer before we just start scanning away. Some scanners, maybe plug and play, but they'll still come with instructions as faras. How to plug in, how to plug into and use your standard on your computer,
01:29
how to install additional drivers if you need Thio or where you can download them if they don't
01:33
already come in CD format. And again, it's always important to check our manufacturer's recommendations of specifications and always re through those instructions. As difficult as it may be when we're ready to get our device plugged in and get it scanning, I'm just checking out those instructions can save us a lot of hassle, especially if
01:52
we're supposed to download and insult the driver
01:55
first or plug in the scanner first. And if we get those mixed up in the wrong order, then we can end up with a computer that's not recognizing the scanner or having toe roll back and delete drivers and start from square one so safe time we just read through the instructions and make sure that we get it on the first go. Um, in addition to like the small
02:15
meet death scanners,
02:15
we have large office scanners where you can scan a document, then actually have that office scanner email it to your computer. So instead of being plugged into your computer, it's simply scans and emails the document to your computer as an attachment.
02:30
And you may even see smallmouth scanners, which are
02:35
a very, very neat product. They're actually they look like a regular sized optical mouse, and then you simply have a document. You take the optical mouse and you move it over the document. And as you do, you can watch on the screen as its piecing together the document just by moving the mouse over it, because it actually has the scan or the small camera
02:53
on the bottom of the mouse.
02:54
It's a very neat innovation, and in certain circumstances it may come in handy. But you always want to do the research as faras the resolution and how high quality a scanner is, depending on your sexual situation and how high quality you need those documents to be after you scan them and put them onto your computer are next
03:14
input device that we're gonna talk about is going to be a barcode reader. Typical home users may not
03:19
ever need to plug into a bar code reader into their computer.
03:22
They wouldn't really haven't used to. You don't need to have a bar code reader sitting around your house all the time
03:28
for most people,
03:30
but
03:30
with the way computers are going and with the way that we're using them in more and more situations because of how power full that can be in the type of software we've developed. Ah, lot of industries. A lot of businesses are actually transitioning from typical cash register machines to small desktop computers, which act as their point of sale machine.
03:51
Now, these point of sale machines have
03:53
bar code readers. That plug in is USB devices, whether they be wireless or plug directly into the USB port. And by installing those additional drivers, they can use the barcode reader that they would normally use for on the cash register and just use it on their computer. That's acts is their point of sale machine.
04:11
You may also see this in devices such a CZ tablets that people are using
04:15
beginning to use more and more for small businesses so we can see how computers air, allowing us to be a lot more user friendly.
04:24
Implement them in situations where previously ah, small business owner may have not had the opportunity or may have not had the equipment available to simply have a card reader available at all times. In addition to our bark barcode reader we now have. We also have a device called a K V M K B M stands for work,
04:43
keyboard,
04:44
video and mouse. What is a K bmdo? Katie M gives us flexibility in a situation where we have multiple computers, but
04:53
I really only have the space for one input and output on one keyboard, mouse and video. Some situations We may have KPMG's that also have speaker inputs say, for instance, you have ah registrar at the front desk, and they have their computer that they used to respond to emails.
05:11
They have another computer that's connected to a different network that they used to
05:15
do scheduling changes, and then they have 1/3 computer that they used for payment processing rather than having three separate keyboards and three separate monitors and 37 mice. They can use a Katie M, which actually takes the keyboard cable, the mouse cable and the monitor cables from
05:32
all three input ports on all three of the different computers,
05:36
centralizes them in one box. And then that one box has the keyboard, video and mouse cable going toe one set of keyboard, video and mounts and then using either certain keys on the keyboard to indicate to the K V M that you want to switch between the different computers or also hard buttons on the K T. M's that you press
05:57
and that illuminate,
05:58
we can switch between those different computers, whether they're 234 even more computers and depending on the number of ports we have available on our K B m say we have our server rack here, and we have our three servers here on the bottom now, especially in server space where kind of limited here, we don't really have the space to have
06:17
multiple monitors and being able to
06:19
and because we don't normally sit here and
06:23
interact with these servers physically, a lot of times will connect over a network. So to save space, we'll have our Katie M. Over here, which we have our video keyboard and mouse from server, A video keyboard and mouse from server be and video keyboard and
06:43
you guessed it mouse from server seat.
06:45
Then we simply have our one screen, our keyboard and our mouse, and we have one set of keyboard, video and mouse cable. And then on top of RK VM. We may have a B and C buttons that illuminate when we press them, and then we have them labeled
07:03
as to which server they correspond with
07:05
so we can see how that saves saves us a lot of space. It makes it easier to interact with those servers without having to have Ah lot of different resource is, and we can just centralize that with a K V M K B M sometimes have. It may have additional software to help them interact,
07:21
but most of the time they are just plug and play devices because all they're doing is receiving input from your single keyboard, video and mouth set up and pushing the output through the same type of cables to the computers. But sometimes they do have built in drivers
07:39
or different software that they may come with. Just always keep that in mind and always read your instructions when installing.
