Clients and Servers
2:04Typically the computers on the Internet either request information or respond to requests. These two actions, requesting and responding, divide computers on the net into two main categories: clients and servers.
They're hundreds of millions of
computers on the Internet, but
0:00
they don't all do exactly the same thing.
0:03
Typically the computers on the net
are either requesting information or
0:06
responding to those requests.
0:10
These two actions,
requesting and responding,
0:13
divide computers on the net into two
main categories, clients and servers.
0:16
While computers can be both the clients
and servers even on the same machine,
0:21
let's take a look at a simple
client-server relationship to find
0:26
out what makes a computer client and
what makes a computer a server.
0:31
A server is both a piece of hardware,
the computer itself and
0:35
a piece of software that
responds to requests.
0:39
While the term server is used to
describe this type of computer,
0:43
not all servers do all things.
0:46
Within the server umbrella,
0:49
there are several different types of
servers including database servers,
0:51
file servers, mail servers, web servers,
and gaming servers among others.
0:55
A server is typically made for production
and speed, meaning they often have
1:01
faster CPUs, high performance RAM,
and more storage capacity.
1:06
In addition, servers are typically more
resilient than your personal devices,
1:11
meaning they have backup power supplies
and storage in case anything goes amiss.
1:16
A client is a computer that
makes requests to a server.
1:21
Clients come in many shapes and sizes.
1:25
The most common ones are desktops,
laptops, tablets, and smart phones.
1:27
The typical client request and
server response cycle
1:33
begins once you pop on the web and
try pulling up your favorite web page.
1:36
At this point your computer is
the client requesting a webpage and
1:41
the computer sending back the webpage is
the server responding to your request.
1:45
This is a classic
client-server relationship.
1:51
Now that you're familiar with
the terminology, client and server,
1:54
let's dig into the main protocols these
computers use to perform their duties and
1:57
share information over the Internet.
