Presenting Presentations
When presenting a presentation you should keep calm and relax so that you could explain things much more comfortable.You should let the audience read so that they wouldn't be bored just listening to you.;

Embedding Objects
Embedding Objects
Embedding objects requires expertise (but not usually).Embedding objects should collaborate with the text also you can express you're text with objects that is why objects are useful.
Transition and Animation
Transition and Animations
Transitions are like slower version of hovering over something.Transitions are great effects for if you hover over it it changes shape it could be longer or bigger.
Animations are also good effects they are sometimes required for some presentations
Presentation Design
Presentation Design
Presentation design is needed if you want to present something beautifully but you to consider a large amount of things.They also have good themes which could help us to present things.
Aspect Ratio is needed to be considered so that you would know what looks good on full screen or with a margin the aspect ratio 4:3 has margin on its sides while the aspect ratio 16:9 doesn't have margin but it could be good too.
Social Networking
Social Networking
Social networks are networks that are mostly free.They are sites that you can be socially yourself but observing netiquette also.
Social Networking is being socially active in social networks they can help you connect to people you want to see you also could chat to them

E-mail(Electronic Mail)
E-mail is commonly used world wide it's fast and it's also not complicated to use than mailing with letters.
Also with e-mail you could file attachments if you want to send a document to someone abroad you could just attach it to an e-mail

Blogging
BLOGGING
Short for Web log, a blog is a Web page that serves as a publicly accessible personal journal for an individual. Typically updated daily, blogs often reflect the personality of the author.Also it is used world wide.
If you want to create a blog you should already have google acount or gmail.
HTML
Hypertext Markup Language
Its a language describing web pages they are used to display document content online they also be used for other purposes other than that they are just simple.
I also learned how to create simple HTML.
These are html tags
I also learned how to create simple HTML.
These are html tags
TML tags are keywords (tag names) surrounded
by angle brackets like <html>
HTML tags normally come in pairs like <b> and
</b>
The first tag in a pair is the start tag, the second
tag is the end tag
The end tag is written like the start tag, with a
forward slash before the tag name
Start and end tags are also called opening tags
and closing tags

Netiquette
Netiquette
Netiquette stands for internet etiquette it is the proper way of behaving online we need it so we don't embarrass ourselves.These are also the rules we need so that we won't disgrace or offend someone.
We also should not post flame bait because it could result to flame wars which is not good online
This is one of the core rules of the netiquette
DON'T DO TO OTHERS WHAT YOU DON'T WANT FOR YOURSELF

Web searches and Evaluating them online
Web searches and Evaluating them online
Search Engine - a search engine it is an organized engine to search for the things you type on the "search" example: google.
Using a search engine does require certain things if you want to search about what pigs eat? just simply type pigs foods because less is more for search engines.
You can also calculate anything example 5632*196=1103872 (i used google for the answer)
Also the weather example the weather of San Francisco,CA,USA
Also you have to evaluate them considering 5 things their site, author,audience,content and currency.
Protocols and DNS
Protocols and DNS
Protocols are the first thing I learned in CS1 2nd Quarter it deals with the internet (internet=interconnecting network)the address of computers.
This is the first of the many protocols
IP - means Internet Protocol it is the primary network of the internet.There are 2 kinds the IPv4 and the IPv6
The IPv4 is the older vesion it is composed 4 bytes which only hve numbers for example 192.168.1.1 they are separated by a decimal
But the IPv6 is composed of 16 bytes it much more complicated than the older example fe83::2cfb:cc9a:298f:fb74%11
TCP - means Transmission Control Protocol it is a connection-oriented protocol it is used by major internet applications such as WWW (world wide web)
UDP - means User Datagram Protocol is the opposite of TCP
FTP- means File Transfer Protocol it is a simple protocol just to transfer files over a TCP based network
SMTP - means Simple Mail Transfer Protocol its standard is E-mail across IPs
Domain Name System
Domain - it is a group of computers with a common set of rules
Subdomain- it is the domain inside a domain

Web Services
Web Services

A Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the web with the servicealways on as in the concept of utility computing. The W3C defines a Web service generally as:
Most web services do not adopt this complex architecture.[citation needed] This article describes it in more detail.
The W3C also states:
Automated tools can aid in the creation of a web service. For services using WSDL, it is possible to either automatically generate WSDL for existing classes (a bottom-up model) or to generate a class skeleton given existing WSDL (a top-down model).
- A developer using a bottom-up model writes implementing classes first (in some programming language), and then uses a WSDL generating tool to expose methods from these classes as a web service. This is simpler to develop but may be harder to maintain if the original classes are subject to frequent change.[4]
- A developer using a top-down model writes the WSDL document first and then uses a code generating tool to produce the class skeleton, to be completed as necessary. This model is generally considered more difficult but can produce cleaner designs and is generally more resistant to change. As long as the message formats between sender and receiver do not change, changes in the sender and receiver themselves do not affect the web service. The technique is also referred to ascontract first since the WSDL (or contract between sender and receiver) is the starting point.[5]
Web services that use markup languages[edit]
There are a number of web services that use markup languages:
- JSON-RPC
- JSON-WSP
- Web template
- Web Services Description Language (WSDL) from the W3C
- XML Interface for Network Services (XINS) provides a POX-style Web service specification format
- Web Services Conversation Language (WSCL)
- Web Services Flow Language (WSFL) (superseded by BPEL)
- WS-MetadataExchange
- Representational state transfer (REST) versus remote procedure call (RPC)
- XML-RPC - XML - Remote Procedure Call
Criticisms[edit]
Critics of non-RESTful web services often complain that they are too complex[6] and based upon large software vendors or integrators, rather than typical open sourceimplementations.
There are also concerns about performance due to web services' use of XML as a message format and SOAP/HTTP in enveloping and transporting.[7]
Regression Testing of Web service[edit]
Functional and non-functional web service testing is done with the help of WSDL parsing and regression testing is performed by identifying the changes made thereafter. Web service regression testing needs can be categorized in three different ways, namely, changes in WSDL, changes in code, and selective re-testing of web service operations. To capture the above, three intermediate forms of WSDL, namely, Difference WSDL (DWSDL), Unit WSDL (UWSDL), and Reduced WSDL (RWSDL), respectively can be used. These intermediate forms are then combined to form Combined WSDL (CWSDL) which is further used for regression testing of the web service. This will help in Automatic Web Service Change Management (AWSCM), by performing the selection of the relevant test cases to construct a reduced test suite from the old test suite.

Computer Science
.jpg)
Computer science is the scientific and practical approach to computation and its applications. It is the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information, whether such information is encoded as bits in a computer memory or transcribed in genes and protein structures in a biological cell.[1] A computer scientist specializes in the theory of computation and the design of computational systems.[2]
Its subfields can be divided into a variety of theoretical and practical disciplines. Some fields, such as computational complexity theory (which explores the fundamental properties of Computational and intractable problems), are highly abstract, while fields such as computer graphics emphasize real-world visual applications. Still other fields focus on the challenges in implementing computation. For example, programming language theory considers various approaches to the description of computation, whilst the study of computer programming itself investigates various aspects of the use of programming language and complex systems. Human-computer interaction considers the challenges in making computers and computations useful, usable, and universally accessible to humans.Source: Wikipedia

Bibliography is the grouping of "citations" for example this picture:
It is like a table of contents Bibliography Style
From: Wikipedia
Bibliography (from Greek βιβλιογραφία bibliographia, literally "book writing"), as a discipline, is traditionally the academic study ofbooks as physical, cultural objects; in this sense, it is also known as bibliology[1] (from Greek -λογία, -logia). Carter and Barker (2010) describe bibliography as a twofold scholarly discipline—the organized listing of books (enumerative bibliography) and the systematic description of books as physical objects (descriptive bibliography).
Text Based Navigation Vs. GUI
Text Based Navigation Vs. GUI
Benefits of text-based software[edit]
Text-based applications typically run faster than software involving graphics does. Text-based applications run faster because the machine does not expend resources on processing the graphics, which generally requires more system resources than text does. For the same reason, text-based applications use memory more efficiently.
Command line interfaces often provide the user more control on the software than a graphical user interface, by taking all the details of a command as parameters and/or by redirecting the outputs between commands. Since the available parameters are not explicitly enumerated, the application can accept many more options than an equivalent GUI-based software: a high number of options in a GUI would make it too complex and impractical, but that doesn't happen in a CLI. Thus the text-based input can provide more flexibility at the cost of learnability and a burden on user's memory.
As a result, text-based software can offer more powerful features than graphic-based software, such as combining the command using a pipeline that allows output of the first command to be used as the input of the next command. Using this, a complex operation can be accomplished in a single command line using a sequence of commands connected together in a pipeline.
In certain circumstances, text-based application offers faster user interaction than the graphic-based software does. Assuming that the user is fluent with typing, the user can enter commands faster than when using the graphical interface, because the users do not have to move their hands from the keyboard to enter different commands.
Limitations of text-based software[edit]
Many users may not find an application with a text-based interface very user-friendly. This is especially true for beginning computer users. While the user may learn how to operate the software by simply playing around or navigating through given options, a text-based system usually requires users to have a more detailed understanding of the commands. Many text-based applications have a menu or help system that shows the user some (or all) of the available options of the software.
Text-based software also has limitations on its output as well. Text-based output may not be considered very attractive to many users, and may be difficult to understand (compared to an output involving graphics). Therefore, certain operations cannot be implemented using text-based software, due to its limitation of range in its input and output.In computing, a graphical user interface (GUI,[1] sometimes pronounced "gooey")[2] is a type of interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs),[3][4][4] which require commands to be typed on the keyboard.
The actions in a GUI are usually performed through direct manipulation of the graphical elements.[5] As well as computers, GUIs can be found in hand-held devices such as MP3 players, portable media players, gaming devices and smaller household, office and industry equipment. The term "GUI" tends not to be applied to other low-resolution types of interfaces with display resolutions, such as video games(where HUD[6] is preferred), or not restricted to flat screens, like volumetric displays[7] because the term is restricted to the scope of two-dimensional display screens able to describe generic information, in the tradition of the computer science research at the PARC (Palo Alto Research Center).Source: Wikipedia
Mail Merge
Mail Merge
Mail merge is a software function describing the production of multiple (and potentially large numbers of) documents from a single template form and a structured data source. The letter may be sent out to many "recipients" with small changes, such as a change of address or a change in the greeting line. Both WordStar (via an ancillary program) and WordPerfect offered this capacity for CP/M and MS-DOS systems. MS Word Mail Merge allows a user to send letters or documents to many people simultaneously; users simply create one document that contains the information that will be the same in each version, and then add placeholders for the information that will be unique to each version.Source: http://en.wikipedia.org/wiki/Mail_merge

Information Technology
Information technology (IT) is the application of computers and telecommunications equipment to store, retrieve, transmit and manipulate data,[1] often in the context of a business or other enterprise.[2] The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several industries are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, e-commerce and computer services.[3][a]

Strengths and Limitations of Computers
Strengths and Limitations of Computers
· CHARACTERISTICS OF
COMPUTER• Computer technology offers fast, effective access to worldwide
information and is therefore an important educational method with rapidly
expanding universal appeal. While the cost of hardware is restrictive for many,
most educational institutions, and many workplaces and public information
centres, now have computer facilities. If your target group has access to
computer technology you may consider using this method.• The Internet is a
worldwide communications and information network linking millions of computers
around the globe. It provides access to online information services through documents
and databases and, through electronic mail (e-mail), allows Internet users to
communicate with other e- mail users in a most cost- and time-efficient manner.
The Internet is one of the words largest and fastest growing computer
networks.• CD-ROMs are laser discs that allow enormous amounts and variety of
information to be stored and retrieved including text, photographs, drawings,
film, video and audio material. Their use as an educational tool is rapidly
expanding in schools, universities and industry.
· STRENGTHS OF
INTERNAL COMPUTER PACKAGES• can be interesting and fun• cater for individual
learning• are interactive• take a discovery-based approach.
· Weakness of internal
computer packages• many people have limited access• systems breakdowns• it can
be expensive to develop CD-ROMs• hardware is expensive.
· Strengths of
television and computer?• Strength is that they can commute information to
everyone efficiently and effectively. It also can be a form of entertainment or
education to everyone.
· WEAKNESS OF
TELEVISION AND COMPUTER• Weakness is that people misusing the concept to
commute bad and misleading information to everyone. Too easily accesible by
anyone at any age at anytime of the day.
· Strengths of
Electronic Surveys• Cost-savings: It is less expensive to send questionnaires
online than to pay for postage or for interviewers.• Ease of Editing/Analysis:
It is easier to make changes to questionnaire, and to copy and sort data.• Faster
Transmission Time: Questionnaires can be delivered to recipients in seconds,
rather than in days as with traditional mail.• Easy Use of Preletters: You may
send invitations and receive responses in a very short time and thus receive
participation level estimates.
· STRENGTHS• Higher
Response Rate: Research shows that response rates on private networks are
higher with electronic surveys than with paper surveys or interviews.• More
Candid Responses: Research shows that respondents may answer more honestly with
electronic surveys than with paper surveys or interviews.• Potentially Quicker
Response Time with Wider Magnitude of Coverage: Due to the speed of online
networks, participants can answer in minutes or hours, and coverage can be
global.
· WEAKNESS OF
ELECTRONIC SURVEYS• Sample Demographic Limitations: Population and sample
limited to those with access to computer and online network.• Lower Levels of
Confidentiality: Due to the open nature of most online networks, it is
difficult to guarantee anonymity and confidentiality.• Layout and Presentation
issues: Constructing the format of a computer questionnaire can be more
difficult the first few times, due to a researchers lack of experien
· WEAKNESS• Additional
Orientation/Instructions: More instruction and orientation to the computer
online systems may be necessary for respondents to complete the questionnaire.•
Potential Technical Problems with Hardware and Software: As most of us (perhaps
all of us) know all too well, computers have a much greater likelihood of
"glitches" than oral or written forms of communication.• Response
Rate: Even though research shows that e-mail response rates are higher,
Opermann (1995) warns that most of these studies found response rates higher
only during the first few days; thereafter, the rates were not significantly
higher.
· STRENGTHS OF
COMPUTER• SPEED:-Computers are much faster as compared to humans beings . A
computer can perform a task in a minute that may take days if performed
manually . A modern computer can execute millions of instructions in one second
.• High storage capacity :-computers can store a large amount of information in
a very small space . A CDROM of 4.7 inch diameter can store all the 33 volumes
of Encyclopedia Britannica and will still have room to store more information.
· STRENGTHS OF
COMPUTER• Accuracy:- Computer can perform all the calculations and comparisons
accurately provided the hardware does not malfunction. • Reliability:- computer
are immune to tiredness and Boredom or fatigue. Thus they are more reliable
than human beings. • Versatility:-computers can perform repetitive jobs
efficiently they can solve labour problem or do hazardous jobs in enviornment
· WEAKNESS OF COMPUTER• Lack of decision making
power :-computer cannot decide on their own. They do not possess power which is
a great asset of human being.• IQ zero:- computers are dumb machines with zero
IQ. They need to be told each and every step.Source: http://www.slideshare.net/Amanjot_kaur/weakness-and-strengths-of-computer
