We want to be sure we grasp the relationship of clients to servers,
and have a shared vocabulary of terms.

Client-server computing
- the basis of much of what we will be doing

The Internet Book by Douglas Comer

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 web server web server SILS website database course course courses, students workspace Lifetime Library research research research research research research 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.

baseline understandings about the tools we will be using

How PCs work and microprocessors

Advice on how to deal with problems as they come up

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.

PC keyboard with the PRTSC key highlighted

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.

a complete print screen capture

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 trim a portion of the screen, install the Snip & Sketch tool, pick the area you want to snip, and an image will be saved to your clipboard.

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.
