ARPANET and Internet development; clients and servers, URLs, DNS, HTTP, browser resources and caching.
Application & programming
Read, process and write text files in C; check opening, conversion, end-of-file and output failures using supplied or recorded readings.
Lecture slides and reading are available above. Recordings are in preparation.
Learning focus
Use basic text-file operations and check results in a bounded task. No database implementation or new hardware.
D: do independently · M: explain and modify a worked example · R: recognize, trace and compare.
Revisit: Reuse loops, strings and pointer arguments when processing a file.
Wednesday 25 Nov · Recitation
Trace file operations and test missing or empty input and expected output.
Start time tentatively 16:30; room to be announced.
Friday 27 Nov · CSE107
