Document cameras, which are also known as visual presenters or visualisers, digital overheads, or docucams. They are real-time image capture devices for displaying an object to a large audience. Just like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. They are, simply put, high resolution web cams, that is mounted on arms so as to facilitate their placement over a page.

Here is a Python program:
tmp = input().split(' ')
c = tmp[0]; s = tmp[1]
ans=0
for i in range(len(s)):
if s[i] == c: ans+=1
# the ans variable stores the number of occurrences
print(ans)

To make sure that data sent from a device is just received by appropriate device we use "<u>Switch</u>"
Explanation:
Switch is the networking device. It is used to connect all the Local area networks in a computer network. The switch store the addresses of all computers over the network. Whenever data packet arrives to the switch, it just read the address of destination computer and just send it to appropriate device instead of all devices.
Hub is also used for this purpose, but it has no ability to read the address and send the packet to all devices over the network.
<em>So, we use Switch to send data to appropriate device.</em>
