Choices of Guest OS Everyone must install Ubuntu (desktop). You can make a copy of Ubuntu and distribute it in the class. Other Linux distributions are welcome. http://en.wikipedia.org/wiki/Comparison_of_Linux_distributions Linux is a good practice to understand theory, please do the following quizzes by yourself.

Quiz: process management Show kernel version Show kernel (file) and its size. Show CPU information. Run a process with lowest priority (least favorable). Run a process (longer 60 seconds), pause, and resume. Run a process (longer 60 seconds) in background, and terminate. Run two processes and connect them using a pipe. Run three processes in background, and bring the second to the front. Run three processes in background, and terminate the first. Show uptime (elapsed time since booting). Note: use the command “sleep” to make a process.

Quiz: memory management Quiz: Storage management Show memory information. Show amount of free and used memory in the system. Quiz: Storage management Make a file, rename, and delete. Make a folder, rename, and delete. Make a file and change permission so that only the owner can read. Make a file and change both owner and group to “root.” Create a symbolic link. Show disk space (harddisk) usage in human-readable format. Show file space usage of “/usr/share/dict/american-english” in human-readable format. Check and repair file system on harddisk. Search for a given filename.

Quiz: Network management Quiz: User management Change password. Show on-line users. Show current users on the system and what they are doing. Enable administrator (root or superuser) account. Add a new user and remove. Quiz: Network management Remote login to Chula server (pylorus.it.chula.ac.th ของบุคคลากร). Transfer a file from Chula FTP (pylorus.it.chula.ac.th ของบุคคลากร). Send an email to someone. Show IP address of your computer. Show IP address of pylorus.it.chula.ac.th (or other servers). Show MAC address of your host computer. Show connection speed to Google.co.th (or other servers). Download a file through HTTP at 0.00AM (or other times).

Quiz: Utility (1) Show the manual page of “man” command. Make a beep sound using “echo.” Change font color to green and background color to black (at a terminal). Show only the first 10 lines of /etc/passwd (or other text files). Show only the last 10 lines of /etc/passwd (or other text files). Show only the line containing “sys” in /etc/passwd (or other text files). Show only the line ending with “land” in /usr/share/dict/american-english. Count the number of lines in /usr/share/dict/american-english. Open /usr/share/dict/american-english in a text editor, and search for “microcomputer.” Make a text file, put your firstname, save and display each character sequentially in hex. Make a text file, put your firstname, encrypt with password protection. Write a program in C, compile, and execute. Write a program in C, compile, and redirect error message to a file. Run a process that will continue after logout. Shutdown in the next 10 minutes.

Quiz: Utility (2) Make a folder with a file inside and compress it to “foldername.tar.gz.” Make a folder with a file inside and compress it to “foldername.zip” and make a checksum. Make two files (firstname and lastname), put them together using “cat,” “>,” and “>>.” Split /usr/share/dict/american-english into 10 files (x00 to x99). Show only the first column in /etc/passwd. Show printer queue. Show current date & time. Show calendar.

Introduction Types of operating systems Operating systems on PCs No operating systems Batch processing Single-tasking Multi-tasking Time-sharing Operating systems on PCs DOS Windows 3.11 Windows 95, 98, ME, XP, Vista, 7 Unix, Linux (GNU – GNU is Not Unix)

No operating systems Connect the robot to PC. Load a program into robot’s memory. Set program counter (PC) to start address Execute the program. Halt. เครื่องใช้ไฟฟ้าง่ายๆ เช่น ทีวี ตู้เย็น มีโปรแกรมที่ทำงานเพียงโปรแกรมเดียว ไม่จำเป็นต้องมี OS

Batch processing A job input (storage) operating system (job queue) input (storage) job control (a file) - commands - output (storage, printer) Hardware CPU Memory Storage Printer

Cooperative multi-tasking CPU Single-tasking Time Multi-tasking idle Advantage: reduce I/O waiting. Disadvantage: a long execution can block other processes. idle idle idle

Preemptive multi-tasking (time sharing) 3 jobs (assume no I/O wait) are submitted almost at the same time (first-come, first-serve). CPU Time Time slice Advantage: quick response for all users/processes. This can be done by timer interrupt.

OS P1 P2 OS ตั้ง timer interrupt แล้วกระโดดไปทำ P1 3 OS ตั้ง timer interrupt แล้วกระโดดไปทำ P1 เกิด timer interrupt OS ยึด CPU กลับไปคืน OS ตั้ง timer interrupt แล้วกระโดดไปทำ P2 CPU ต้องมีฮาร์ดแวร์ที่เป็น timer interrupt เพื่อสนับสนุน OS ที่ทำงานแบบ time sharing P1 2 P2

DOS single-user, single-task (no multi-tasking) only text mode, no GUI

Windows 3.1x Graphical user interface (GUI) Cooperative multi-tasking Windows 3.1 uses cooperative multitasking - meaning that each application that is in the process of running is instructed to periodically check a message queue to find out if any other application is asking for use of the CPU and, if so, to yield control to that application. However, many Windows 3.1 applications would check the message queue only infrequently, or not at all, and monopolize control of the CPU for as much time as they required. A preemptive multitasking system like Windows 95 will take CPU control away from a running application and distribute it to those that have a higher priority based on the system's needs.
