7. Home Work • Topics may be assigned or chosen. • Search for topics on the internet. • Group search or individual searches. • Email link to web source of your best info and a short (50 words or more) description of your understanding. not copied and pasted info., your original thoughts

8. Home Work: Why? • Best way to learn is to do it. • Students enter College with different level of Computer skills. • Research is what the internet was designed for. • I am not all knowing and I want you to learn more then I can teach. • Learn how to verify information from the internet. • Websites are important for professional growth.

9. RIT IT resources • Take advantage of Virtual Resources • Servers & computer labs • Email and Web space • Free dial up and Hi speed access • SIS (Student Information System) and Library system access (Electronic Resources)

10. RIT Network • Two OC3 (155.52 Mbps) and one T3 (45 Mbps) connection • Hi speed network using Ethernet • Connection from on-campus (10 Mbps / 100 Mbps) • RIT DialIP service • connection from off-campus • RIT’s modem pool has 312 modems that operate at a speed of 56 Kbps. • Wireless connection • Wireless networking is enable in many campus buildings. • You need wireless card (ex. Cisco 350, Apple Airport) and your laptop

11. Servers • OSFcluster - grace.rit.edu • Unix server • login with your DCE account • has quota( user storage limit ) 10M • your RIT personal home will be published in this server • VMScluster - ritvax.rit.edu • VAX machine running VMS, which is quite out of date • login with your DCE account • poor performance ( not recommended to use ) • VAX history: An interesting writing about the person experience with VAX http://www.webmythology.com/VAXhistory.htm • ciasserv.rit.edu • shared by CIAS students and faculty • approaching this server via telnet is blocked. But can be accessed by Appletalk protocol or Windows networking. (R: drive )

12. CIAS Labs • Windows: • 3D Lab (Room 1212) • PC Lab (Room A410) • MAC : • Gannett MCL (Room 1226,1230) • New Media Lab (7A- 1303) • Barschel Lab (7A-1611) • Booth Lab (7A-1540) • For lab operating hours : • http://www.rit.edu/~wwwits/services/computer_labs/labs/all_hours.html

13. RIT Email System

14. RIT DCE account • Setting up your RIT DCE (Distributed Computing Environment) account • ITS Help Desk (Gannett 1st. floor Room 1113) • Change your password when you first logged in. (Change it frequently for security)

15. Email Basic • E-mail is the exchange of message between 2 computers (via a network of computers, routers, servers, etc.) • For 2 computers to communicate , they both need to be “awake” (one computer cannot be switched off!)Hence, mail is generally sent to a mail server which manages the traffic of massages. • To read the mail, a “user” needs an account on this server and a “mail client ” (which can present the data to you in a friendly fashion - Outlook, Netscape, Eudora)

16. EMail Protocol - SMTP • SMTP(Simple Mail Transfer Protocol) • a protocol for sending e-mail messages between servers • generally used to send messages from a mail client to a mail server • the messages can then be retrieved with an e-mail client using either POP or IMAP

17. EMail Protocol- POP • POP (Post Office Protocol) • a protocol used to retrieve e-mail from a mail server. • There are two versions of POP. The first, called POP2, became a standard in the mid-80's and requires SMTP to send messages. The newer version, POP3, can be used with or without SMTP. • Offline solution. You download all messages from a receiving e-mail server computer to your computer

18. EMail Protocol - IMAP • IMAP ( Internet Message Access Protocol) • A protocol for retrieving e-mail messages. • Developed at Stanford University in 1986. • The latest version, IMAP4 • online solution—you have to be connected to the server to retrieve your mail • The main advantage of IMAP is that you can access the account from different locations and different computers, since both new and saved messages are left on the server.

19. Mail Client Configuration • Incoming Mail Server Address • mail server’s name or address. • (mail.myserver.net, pop.myserver.com, or imap.myserver.com) • Username or Account ID • username you’ve been assigned for your e-mail account. • Password. • Outgoing Mail Server Address • This is the server address for outgoing messages • Usually SMTP server address of your ISP

20. Stanford University Email System

21. Mail Servers in RIT • Exchange server - main mail server • Incoming mail server : mymail.rit.edu • Outgoing mail server : smtp-server.rit.edu • Outlook Web Access server : mymail.rit.edu • Quota (Storage limit) :20MB (30M for only incomming mail, 40M maximun) • OSFmail server - old • IMAP (or IMAP4, IMAPv4; incoming e-mail) server: osfimap.rit.edu • SMTP (outgoing e-mail) server: osfmail.rit.edu • VMSmail server - old • IMAP (or IMAP4, IMAPv4; incoming e-mail) server: vmsimap.rit.edu • SMTP (outgoing e-mail) server: vmsmail.rit.edu

22. Mail Client • To retrieve your mail, you need email client, an application which connects to server and request your mail contents and display it. • Webmail – read them using web browser • Go to mymail.rit.edu to read your mail • Microsoft Extourage, Apple Mail, Outlook, Netscape

23. Operating Systems(OS)

24. Operating System(OS) • The most important program that runs on a computer, that enables the computer to interact with the user and any peripheral devices such as printers, disk drives, and monitors. • Operating systems provide a software platform on top of which other programs can run. Your choice of OS determines applications that you can use. • Command line interface & GUI (Graphic User Interface) • Windows XP home and pro, 2000, ME, 98, 95 dos. • Mac. OS X, OS 9(classic) • Unix proprietary like Irix, Sun. • Linux:Unix and it’s open source mutations like Red hat, Gnome.

25. Large Operating System • Multi-user : Allows two or more users to run programs at the same time. Some operating systems permit hundreds or even thousands of concurrent users. • Multiprocessing : Supports running a program on more than one CPU. • Multitasking : Allows more than one program to run concurrently. • Multithreading : Allows different parts of a single program to run concurrently. • Real time: Responds to input instantly

26. Mac OS X

27. Mac OS X • Apple's flagship OS, now in its fourth major iteration, Mac OS X 10.3 "Panther”. • Mac OS version in RIT Labs: 10.3.5 & 9.2.2 • Unix based (Server features) • multitasking, dynamic RAM allocation, multithreading, symmetrical multiprocessing, micro-kernal architecture. • Classic compatibility • GUI, Finder,Classic/Native mode, System Preference

28. Homework #1 • Search for information on the “invention of computer” • Search for “standard organization” in relation to computer industries.
