Client-server computing

Client-server computing - the basis of much of what we will be doing
We want to be sure we grasp the relationship of clients to servers,
and have a shared vocabulary of terms.

Client-server computing

... is the interaction between two programs when they communicate across a network. A program at one site sends a request to a program at another site and awaits a response.

The requesting program is the client.

Assuming we are using our laptops as a client, we might want to know how laptops work.

The program satisfying the request is the server.

For example, SILS has a number of servers, for a number of purposes.

Internet Protocol (IP) Address	Name	specific function
152.2.11.66	ruby.ils.unc.edu	web server
152.2.11.77	jade.ils.unc.edu	web server
152.2.11.69	jasper.ils.unc.edu	SILS website
152.2.11.67	pearl.ils.unc.edu	database
10.4.80.5	db2.ils.unc.edu	course
10.4.80.18	jupyter.ils.unc.edu	course
152.2.11.68	opal.ils.unc.edu	courses, students workspace
152.2.11.71	diamond.ils.unc.edu	Lifetime Library
152.2.11.72	gallifrey.ils.unc.edu	research
152.2.11.75	topaz.ils.unc.edu	research
152.2.11.79	sils-jasrv.ad.unc.edu	research
152.2.11.76	red.ils.unc.edu	research
34.206.160.36	video.ils.unc.edu	research
18.233.182.83	focus.ils.unc.edu	research
152.2.11.78	sils-pelican.ad.unc.edu	print server, admin tools

Assuming we want to retrieve something from a server over the web, we might want to know how web servers work.

Mac vs. Windows: Which Is Right for You?

Terminology

It's good to be cognizant of the relationship of memory to storage, and the specific meaning of each term.
For example, what is RAM? (in more detail)

What are operating systems? We are familiar with Windows and Apple on our clients, but Linux and Android are starting to become challengers.

Wikipedia lists lots and lots of operating systems.

What does open source mean?

one simple tool that we will use a lot

Learn how to use the screen capture tool.

If you want to capture the entire screen, press the Print Screen button and an image of the screen will be saved to your clipboard.

If you want to capture the active window, press the ALT button + the Print Screen button and an image of the active window screen will be saved to your clipboard.

If you want to capture a part of the screen, and you use Windows 10, press “Windows + Shift + S”. Your screen will appear grayed out and your mouse cursor will change. Click and drag on your screen to select the part of your screen you want to capture. A screenshot of the screen region you selected will be copied to your clipboard. You can paste it in any application by selecting Edit > Paste or pressing Ctrl + V, just as you’d paste a full-screen shortcut taken with the Print Screen key.

If you use a Mac, there are several keyboard combinations that can be used to take screenshots in Mac OS X

Mac users

The lecturer will use a Windows OS laptop most of the time. On occasion, the interface in Windows will not match the interface in a Mac. While we will try to have examples for all operating systems, it will be useful if, when you find that the Mac view is different, that you take a screenshot of the Mac environment and send it to the instructor. The instructor will ensure that the Mac screenshot is integrated into the class pages pertaining to the situation in which the screenshot was taken.
