ü Unicode A character encoding standard developed by the Unicode Consortium that represents almost all of the written languages of the world. The Unicode character repertoire has multiple representation forms, including UTF-8, UTF 16, and UTF-32. Most Windows interfaces use the UTF-16 form. ü Unicode Character System (UCS) An international standard character set reference that is part of the Unicode standard. The most widely held existing version of the UCS standard is UCS-2, which specifies 16 -bit character values currently accepted and recognized for use to encode most of the world's languages. ü Unicode Transmission Format 8 (UTF-8) A character set for protocols evolving beyond the use of ASCII. The UTF-8 protocol provides for support of extended ASCII characters and translation of UCS-2, an international 16 -bit Unicode character set. UTF-8 enables a far greater range of names than can be achieved using ASCII or extended ASCII encoding for character data.
ü ü ü ü ü ü ü ü ü Unicode® control characters Unicode control characters are tags that help with text flow and direction for languages such as Arabic and Hebrew. To install these languages, use Regional and Language Options in Control Panel. These descriptions are adapted from The Unicode Consortium. The Unicode Standard, Version 2. 0. Reading, Massachusetts: Addison-Wesley Developers Press, February 1997. Left-to-right mark (LRM) Right-to-left mark (RLM) Acts exactly like right-to-left characters, except that it is not displayed. RLM does not have any other semantic effect. Zero width joiner (ZWJ) Prevents the joining of consecutive characters on output. Zero width non-joiner (ZWNJ) Adds a non-joiner between two characters to prevent them from forming a cursive connection with each other when rendered. Start of left-to-right embedding (LRE) Signals that a piece of text is to be treated as embedded left-to-right. For example, an English quotation in the middle of an Arabic sentence could be marked as being embedded left-toright text. (LRE affects word order, not character order. ) Start of right-to-left embedding (RLE) Signals that a piece of text is to be treated as embedded right-to-left. For example, a Hebrew phrase in the middle of an English quotation could be marked as being embedded right-toleft. (RLE affects word order, not character order. ) Start of left-to-right override (LRO) Overrides bidirectional character types when required for special cases, such as for part numbers. LRO forces characters to be treated as strong left-to-right characters. Start of right-to-left override (RLO) Overrides bidirectional character types when required for special cases, such as for part numbers. RLO forces characters to be treated as strong right-to-left characters. Pop directional formatting (PDF) Terminates the effects of the last explicit code (either embedding or override) and restores the bidirectional state to what it was before the last LRE, RLO, or LRO control characters. National digit shapes substitution (NADS) Uses national digit shapes to display the U+0030 -U+0039 (ASCII numerals). The national digit shapes are determined by the current user locale. Nominal (European) digit shapes (NODS) Uses the nominal digit shapes for the digits U+0030 -U+0039 (ASCII digits). Nominal digit shapes are Western digits. Activate symmetric swapping (ASS) Indicates whether the term LEFT or RIGHT in pairs of character names, such as parentheses, should be interpreted as meaning opening or closing, respectively. (The default state is activated. ) Inhibit symmetric swapping (ISS) Turns off the symmetric swapping of characters such as parenthesis, so that left and right continue to mean left and right facing, as opposed to opening and closing, when symmetric swapping is on. Activate Arabic form shaping (AAFS) Controls the shaping behavior of the Arabic compatibility characters. During the presentation process, certain letterforms may be joined together in cursive connection or ligatures. The shaping selector codes indicate that the character shape determination (glyph selection) process used to achieve this presentation effect is to be either activated or inhibited. (The default state is inhibited. ) Inhibit Arabic form shaping (IAFS) Inhibits the character shaping determination process, so that characters are not shaped based on position. Record Separator (Block separator) (RS) Begins a new line after each line separator. Unit Separator (Segment separator) (US)

UNIVAC Universal Automatic Computer was commercially available from Remington Rand in 1951; it incorporated stored memory and a CPU central processing unit
Vacuum tubes were used in ENIAC; large and hot! Transistors were invented in 1948 and used in computers by 1956
IBM 360 was the computer prototype of the 1960’s and included printer, tape and disk storage, and stored programs such as COBAL (Common business oriented language) and FORTRAN (formula translator); By the mid-1980’s IBM earned over $100 billion in profits.
IBM 650 was a cluster of computers that processed data for large institutions; in the movie ‘ 2001’ what was the name of the computer that ran the US space mission?
DEC PDP 8 was a minicomputer that we used in the lab in 1972; it represents the transition from mainframes to PC’s. By the mid 1970’s, personal desktop computers were being mass marketed by Commodore, Radio Shack, and Apple.

The mouse was fundamental to the development of the Graphical User Interface. GUI revolutionized use of computers through the concept of icons and point and click control which replaced cumbersome text command strings. In a TV ad during the 1984 superbowl, the Macintosh computer was introduced by Apple. Microsoft later ‘adapted’ this concept into the Windows operating system.
The IBM Punch Card “do not fold, spindle, or mutilate”
This paper tape contains the first version of a BASIC language interpreter written by Bill Gates and Paul Allen for the MITS Altair 8800 computer while both were students at Harvard University. The Altair was a computer kit that appeared as the cover story of the January 1975 issue of Popular Electronics magazine. The BASIC interpreter allowed Altair owners to program their machines using English-like commands. Altair BASIC was the first mass -produced commercial program written by Gates's company, known at the time as "Micro Soft. "
History of Data Storage (Portability is Everything) • Punch cards: cards stored both operating instructions and data • Ticker tape: feed of individual punch cards was too slow…the ticker • • • tape, a thin strip of paper "streamed" to get a consistent data slow Magnetic tape: both punch cards and ticker tape were far too slow Magnetic disk: able to read data "randomly" from a disc coated in magnetically-switchable bits, rather than from a linear tape. Data speeds and storage capacity improved Floppy and Zip disks: removeable storage … explodes the personal computing industry; from 1. 44 Mb ‘floppies’ to 100 -750 Mb zip disks Multi-platter drives and RAID systems : Redundant Arrays of Independent Disks … introduced the concept of redundancy in computer systems for reliability Optical storage: In 1962 the diode laser was developed, allowing mass manufacture of optical drives; from music and software read-only to recordable 700 Mb CD and 4. 7 Gb DVD USB Flash Memory Key Storage: 16 Mb to 1 Gb, $21 -313; does not require a disk dive rather uses a USB interface
Internet World Wide Web Fiber-optic cable revolutionized computer communication. Growth in connectivity from LAN local area network in an office building to internet www world wide web. The latest innovation is mobile or wireless, such as wireless internet system at the School of Medicine.
The Handheld Calculator ushers in the era of personal electronic computers. The HP-35 Scientific Calculator (1972) was the world's first handheld scientific calculator and HP's first product that contained both integrated circuits and LEDs, combining miniaturization and portability with powerful computing technology. PDA – Personal Digital Assistant 1996, original Palm Pilot: PDA’s rely on stylus/touch-screen technology and handwriting recognition programs for data entry. PDA’s keep addresses and calendars, crunch numbers, play games or music and download information from the Internet. They're designed to complement a personal computer, not replace one; communication between PDA and PC is referred to as data synchronization. May have wireless features including e-mail and cell phone.
The Origin of Computer Bugs Thomas Edison talked about bugs in electrical circuits in the 1870 s. When the first computers were built during the early 1940 s, people working on them found bugs in both the hardware of the machines and in the programs that ran them. In 1947, engineers working on the Mark II computer at Harvard University found a moth stuck in one of the components. They taped the insect in their logbook and labeled it "first actual case of bug being found. " The words "bug" and "debug" soon became a standard part of the language of computer programmers.

General Purpose Computers • What makes a PC different? • Today your PC can’t play Final Fantasy IX. • Tonight you go buy the Final Fantasy IX CD-ROM • Tomorrow your PC can play the game! • PC’s are general-purpose computers.
The Stored Program • Idea is simple: • Build a machine that can execute certain instructions. • Then, write down different lists of instructions (programs) to accomplish different things. • One program plays an adventure game • Another program lets you write papers • Another lets you surf the Internet

Using wildcard characters A wildcard character is a keyboard character such as an asterisk (*) or a question mark (? ) that is used to represent one or more characters when you are searching for files, folders, printers, computers, or people. Wildcard characters are often used in place of one or more characters when you do not know what the real character is or you do not want to type the entire name. Wildcard character Uses Asterisk (*) Use the asterisk as a substitute for zero or more characters. If you are looking for a file that you know starts with "gloss" but you cannot remember the rest of the file name, type the following: gloss* This locates all files of any file type that begin with "gloss" including Glossary. txt, Glossary. doc, and Glossy. doc. To narrow the search to a specific type of file, type: gloss*. doc This locates all files that begin with "gloss" but have the file name extension. doc, such as Glossary. doc and Glossy. doc. Question mark (? ) Use the question mark as a substitute for a single character in a name. For example, if you type gloss? . doc, you will locate the file Glossy. doc or Gloss 1. doc but not Glossary. doc.

Search operators If you're not finding what you're searching for after using our basic search tips, try a search operator. Add these symbols or words to your search terms in the Google search box to gain more control over the results that you see. Don’t worry about memorizing the operators - you can use the Advanced Search page to generate many of these searches. When you search using an operator, don't add any spaces between the operator and your query. A search for site: nytimes. com will work, but site: nytimes. com will not. Search for an exact word or phrase "search query" Use quotes to search for an exact word or set of words. This option is handy when searching for song lyrics or a line from literature. "imagine all the people" Tip: Only use this if you're looking for a very precise word or phrase, because otherwise you could be excluding helpful results by mistake. Exclude a word -query Add a dash (-) before a word or site to exclude all results that include that word. This is especially useful for synonyms like Jaguar the car brand jaguar the animal. jaguar speed -car or pandas site: wikipedia. org Tip: You can also exclude results based on other operators, like excluding all results from a specific site. Search within a site or domain site: query If you are looking for more results from a certain website, include site: in your query. For example, you can find all mentions of "olympics" on the New York Times website like this: olympics site: nytimes. com Tip: Also search within a specific top-level domain like. org or. edu or country top-level domain like. de or. jp. olympics site: . gov Search for pages that link to a URL link: query Using the link: operator, you can find pages that link to a certain page. For example, you can find all the pages that link to google. com. link: google. com Tip: You can also search for links to specific pages, like google. com/images. link: google. com/images Search for pages that are similar to a URL related: query To find sites that are similar to a URL you already know, use the related: operator. For example, when you search for related sites to the New York Times, you'll find other news publication sites you may be interested in. related: nytimes. com Include a "fill in the blank" query * query Use an asterisk (*) within a query as a placeholder for any unknown or wildcard terms. Use with quotation marks to find variations of that exact phrase or to remember words in the middle of a phrase. "a * saved is a * earned"
Google Image Search The Advanced Image Search page lets you tailor results in the following ways: • Search for a specific phrase (this is also possible by "surrounding your search with quotes"). • Search for words related to your search. • Exclude words (you can also do this in the search box by putting a minus sign right before the -word you want to exclude). • Filter by image size and aspect ratio. • Filter by image coloration. • Filter by site or domain. • Filter by usage rights labeling. ﻫﺮ ﺍﻧﺪﺍﺯﻩﺍی ﺑﺰﺭگ Ø ﻣﺘﻮﺳﻂ Ø ﻧﻤﺎﺩ Ø ﻫﺮ ﺭﻧگی ﺗﻤﺎﻡ ﺭﻧگی Ø ﺳیﺎﻩ ﻭ ﺳﻔیﺪ Ø ﺷﻔﺎﻑ Ø ﻫﺮ ﻧﻮﻉ چﻬﺮﻩ Ø ﻋکﺲ Ø ﻗﻄﻌﻪ ﻫﻨﺮی Ø ﺳیﺎﻩ ﻗﻠﻢ Ø ﺍﻧیﻤیﺸﻦ Ø ﻫﻤﻪ ﺯﻣﺎﻥﻫﺎ ۴۲ ﺳﺎﻋﺖ Ø گﺬﺷﺘﻪ ﻫﻔﺘﻪ گﺬﺷﺘﻪ Ø ü ü

What are Blogs? ü "Blog/Web. Log: a web page containing brief, chronologically arranged items of information. A blog can take the form of a diary, journal, what's new page, or links to other web sites. " Scott, Peter. (2001) “Blogging: Creating Instant Content for the Web. ” Internet Librarian 2001, Pasadena, CA http: //library. usask. ca/%7 Escottp/il 2001/definitions. html
Why blog? ü Easy method of web publication ª Not necessary to know HTML ª Content is easily reusable and distributed via RSS; can add updated content to websites ü Management of information for personal or organizational use ü Web based ü Instant ü Reverse chronological ü Links, within entries and collected separately ü Community participation ü Types: personal, political, community, academic, corporate, professional, subject specialists, institutional, news, service ü Bloglines and blogrolls

Summary ü Blogging is for individuals ü RSS (and syndication) help build connectivity, and communities ü Aggregators support simple APIs so it’s easy to build functions that integrate these tools with others (blogsites, portals, other. . ) ª Richer communities via richer functionality ª No conscious high-level architecture: people just try new ideas, and seeing what works (or doesn’t) ª A heterogenous collection of apps, sharing using simple protocols, APIs. ü Each application and protocol is simple (limited scope, easy to use ), and open (encourages reuse, extension) URL as a reference / API is key to this model
