  Actually aku bukan ap, tak salah kan if we want to trust somone else buttt, sometimes benda ni akan makan diri kita balik, sebab ap aku ckap mcm ni hanyalah untuk mengingati antara satu sama lain, iyelah dunia ni hanyalah sementara (eh, apa kaitan?) hahaha, whatever bytw, setiap orang mesti ada melakukan kesalahan right? termasuklah diri yang bercakap ni,. ( bercakap ke aku?, hahaha) kay, ignore that!

computer generation




First Generation (1940-1956) Vacuum Tubes
  • ·         The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
  • ·         First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.
  • ·         First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.


Second Generation (1956-1963) Transistors

  • ·         Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. 


  • ·         Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology.

The first computers of this generation were developed for the atomic energy industry.

Third Generation (1964-1971) Integrated Circuits


The development of the integrated circuit was the hallmark of the third generation of computers.
·         Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.
·         Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitorsand interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory.
·          Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.

Fourth Generation (1971-Present) Microprocessors
  • ·         The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and memory to input/output controls—on a single chip.
  • ·         As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.

Fifth Generation (Present and Beyond) Artificial Intelligence


·         Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today.
·          The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come.
·         The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.

Internet Service

a) Electronic Mail


  •  It is a method of exchanging digital messages from an author to one or more recipients. Modern email operates across the Internet or other computer networks.

  •  the term electronic mail was used generically for any electronic document transmission. For example, several writers in the early 1970s used the term to describe fax document transmission.

Advantages
  • Emails are delivered extremely fast when compared to traditional post.
  • Emails can be sent 24 hours a day, 365 days a year.
  • Webmail means emails can be sent and received from any computer, anywhere in the world, that has an Internet connection.
  • Cheap - when using broadband, each email sent is effectively free. Dial-up users are charged at local call rates but it only takes a few seconds (for conventional email, eg text only) to send an email.
  • Emails can be sent to one person or several people.



Disadvantages

  • The recipient needs access to the Internet to receive email.
  • Viruses are easily spread via email attachments (most email providers scan emails for viruses on your behalf).
  • Phishing - sending an email to a user falsely claiming to be a legitimate company to scam the user into providing information, such as personal information and bank account numbers on a bogus website. The details will then be used for identity theft.
  • No guarantee the mail will be read until the user logs on and checks their email.
  • Spam - unsolicited email, ie junk mail.

b) Facebook

 
  1. Facebook is an online social networking service, whose name stems from the colloquial name for the book given to students at the start of the academic year by some university administrations in the United States to help students get to know each other.
  2. Users must register before using the site.
  3. After which they may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile.



Advantage

  • Facebook is free and it's one of the best medium for communication.
  • It can connect to different people from anywhere in the world because almost every people around the world use Facebook . This gives us the opportunity to know more about their custom and tradition,culture, religion.
  • Finding Old friends. When a friend goes away to any other place, we often don't get the chance to communicate with him or her.
  • Students can use Facebook for group study by creating a group only for studying. There you can share any information about your projects , home work , assignments , exams , due date etc.


Disadvantage

  • Fake profile and ID! Fake profile is one of the biggest disadvantage of Facebook. Now it is easier to create fake profile. People often use fake profile to insult or harass someone they don't like.
  • There are plenty of groups and Fan pages out there which are being created to abuse or violate other religion , personalities , nation etc. This kind of racist disgusting activities decreasing some popularity.
  • Facebook often brings bad effects on students results.




 

c) Video Conferencing


Videoconferencing is the conduct of a videoconference (also known as a video conference or videoteleconference) by a set of telecommunicationtechnologies which allow two or more locations to communicate by simultaneous two-way video and audio transmissions.

Advantage
1. Significant Travel Savings

  • The constant climb of air travel prices barely seems like news anymore, and smart organizations are finding alternatives.  Not only is video conferencing a direct replacement for many in-person business trips, but because there is virtually no cost to add additional key employees to a virtual meeting, you can easily bring the right team together.


2. Improved Communication

  • Video conferencing restores many visual cues necessary in long distance communication. Social psychologist Ray Birdwhistell demonstrated years ago that non-verbal communication constitutes about two-thirds of the communication between people. For example, eye contact enables us to ‘get’ a message from a speaker that voice communication alone may not successfully convey, creating essential social bonds and shared understandings. Audio conferencing and e-mail lose these non-verbal cues.


3. Increased Productivity

  • Everyone has experienced the classic never ending “conference call from hell,” and video conferencing all but eliminates those problems, even from large group calls.  Important meetings are shorter and more effective.  Video conferencing users report saving a minimum of two hours a week with the technology. The interactivity of group collaboration and document sharing greatly increases productivity.


4.Conferencing Quality

  • All of the pros and cons of video conferencing hinge on quality. Early versions of video conferencing quality had uneven clarity of the audio and video broadcast. Today, these problem still remain for low-end and consumer systems.  However, state-of-the-art technology now delivers excellent, reliable audio and video quality, making this one-time disadvantage one of perception, not reality.
Disadvantage


1. Physical Presence

  • Salespeople can truly read a potential customer’s response, customers can assess a salesperson’s credibility, leaders can gauge their audience to see whether they caught the organization’s vision, and managers determine whether to hire an applicant.Organizations concerned about physical presence can begin by using video conferencing in the most appropriate applications, such as training and internal meetings, where the gains from video conferencing are dramatically superior to a traditional audio conference call.

2. Quality Systems are Not Free

  • Some perceive conferencing systems to be expensive, but this is no longer true.  In the early days, organizations installed fully-outfitted central meeting rooms with cameras, lighting and hardware.  Today, high quality video conferencing is possible via cloud-based systems, and the need for expensive end-point hardware has dropped significantly.  Many organizations now install a centralized gateway that connects participants via a broadband network. 

3. User Familiarity
  • While some people seamlessly adapt to change, including new technology, others find change disruptive.  Today’s video conferencing systems are significantly easier to use, and some systems (like those available from LifeSize) eliminate intimidating remote controls and multiple devices that were common in the past.  In fact, LifeSize now supports workers’ existing mobile devices (the “bring your own device” or BYOD phenomenon) such as mobile phones and tablets, making the experience far more familiar and accessible than in the past.








d) Twitter


  • Twitter is an online social networking service and microblogging service that enables its users to send and read text-based messages of up to 140 characters, known as "tweets".
  • Twitter is fast becoming a leading online community as well as a powerful social marketing tool. The beauty of Twitter lies in its simplicity. Compared to other community-oriented web services like Facebook and MySpace, Twitter is streamlined, simple, and straightforward.
Advantage
  • It takes less than a minute to create an account with Twitter and start “tweeting.” The rules of the game are pretty straightforward. Registration is instant, and there is no need to follow up with a confirmation email.
  • Twitter limits its updates to 140 characters, so there’s no need (or temptation) to launch into long-winded prose or to over-explain your thought. There is only one main screen, so you never have to search around for what you’re looking for.
  • You can follow anyone on Twitter, and anyone can follow you. Although there is an option to block someone from following you, unlike with Facebook, you don’t have to actively accept someone’s friendship in order for them to see your updates.


Disadvantage

  • because Twitter is so easy to join, virtually everyone has a Twitter account, so their server tends to get overloaded easily.
  • Because Twitter is so simple, there is little sophistication to the presentation. Your profile is lean and mean. You can only have one photo attached to your profile at a time, and little detailed information about yourself. 
  • You may not have any idea who is really following you.

e) Keek

Keek is a free online social networking service that allows its users to upload video status updates, which are called "keeks". Users can post keeks to the keek website using a webcam or via the Keek mobile apps for iPhone, Android, BlackBerry, or Windows Phone. Users can also reply back with text or video comments, known as "keekbacks", and share content to other major social media networks. There is also an embed option so users can embed their keeks into a blog or website.

Advantage

  •  But to keep it virtually, you get the chance to let it stand for as long as it can be. It has video sharing apps that make easy uploading possible. You can even share it fast via social networking sites. 


 

d) Youtube

 
YouTube is a video-sharing website, created by three former PayPal employees in February 2005 and owned by Google since late 2006, on which users can upload, view and share videos.

Advantage

  • easy to use upload process
  • many formats are accepted
  • You can post a link to your site or blog
  • good branding opportunity 
  • you get traffic and you could get a lot of it
  • good chance to interact with your audience.



Disadvantage



  • they can delete your content for whatever reason they want
  • limitations on the length of the video
  • your content can be scrapped and stolen
  • slow upload process
  • lots of spam comments lately


 

e) Blog 

 
  • It is a discussion or informational site published on the World Wide Web and consisting of discrete entries ("posts") typically displayed in reverse chronological order (the most recent post appears.
  •  A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic. 
  • The ability of readers to leave comments in an interactive format is an important contribution to the popularity of many blogs.
  •  Most blogs are primarily textual, although some focus on art (art blogs), photographs (photoblogs), videos (video blogs or "vlogs"), music (MP3 blogs), and audio (podcasts). 
  • Microblogging is another type of blogging, featuring very short posts. In education, blogs can be used as instructional resources. These blogs are referred to as edublogs.


f) Internet Relay Chat

 
Internet Relay Chat (IRC) is a protocol for live interactive Internet text messaging (chat) or synchronous conferencing. It is mainly designed for group communication in discussion forums, calledchannels,but also allows one-to-one communication via private message as well as chat and data transfer,including file sharing.


example of IRC

g) Online shopping

 
  • Online shopping or online retailing is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internetusing a web browser
  • Alternative names are: e-web-store, e-shop, e-store, Internet shop, web-shop, web-store, online store, and virtual store. 
  • An online shop evokes the physical analogy of buying products or services at a bricks-and-mortar retailer or shopping center; the process is called business-to-consumer (B2C) online shopping. 
  • In the case where a business buys from another business, the process is called business-to-business (B2B) online shopping.



h) Search engine


  • A web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a specialist in web pages, images, information and other types of files


Advantage

  • There are three very compelling advantages of most search engines.
  • The indexes of search engines are usually vast, representing significant portions of the Internet, offering a wide variety and quantity of information resources.
  • The growing sophistication of search engine software enables us to precisely describe the information that we seek.
Disadvantage

  • Regardless of the growing sophistication, many well thought-out search phrases produce list after list of irrelevant web pages. The typical search still requires sifting through dirt to find the gems.
  • Using search engines does involve a learning curve. Many beginning Internet users, because of these disadvantages, become discouraged and frustrated.



i) Newsgroup


  • Newsgroups are Internet discussion forums where groups of users with common interests gather to talk about everything from software to comic books to politics. Unlike e‑mail messages, which are visible only to the sender and specified recipients, newsgroup messages can be read by anyone who views the group that they're posted in. Newsgroups are international in scope, with participants from all corners of the Internet.
Advantage
  • Advantages of newsgroups.Newsgroups are similar in some ways to mailing lists, but they tend to have a better structure, which makes it more likely that they will be around for much longer than a mailing list. 
  • It is also easier to find a newsgroup, and they sometimes have a moderator, who is someone who makes sure that things stay on track and do not disintegrate into something that is socially unpleasant
  • More often than not, you will be able to find a FAQ (frequently asked questions) section on a newsgroup, which is always helpful for those who are not sure of anything. These questions tend to be the ones that are asked repeatedly and so negate the need for constantly answering the same question. 
  • Naturally, if a query is not answered on the FAQ page, it is possible to submit a question and get it answered.


Disadvantage

  • A newsgroup is not as quick as an email or even a mailing list. Very often there will be a delay of at least a day, often longer, before a response is given.
  • Another disadvantage to a newsgroup is that the information on them is submitted by people who may have no real idea of what they are talking about, so you need to be aware of this potential flaw and keep your mind open to alternatives, and to be prepared to do some more background research if it is important.
  • A serious disadvantage to newsgroups is that they can sometimes attract people who you wouldn't give the time of day to if you were to meet them in person. This is especially worrying if children have access to newsgroups.




f) Mailing list


  • A mailing list is a collection of names and addresses used by an individual or an organization to send material to multiple recipients. The term is often extended to include the people subscribed to such a list, so the group of subscribers is referred to as "the mailing list", or simply "the list".
Advantage
  • - Quick delivery and reply of messages
  • - Convenient
  • - Can contact a group of people at once
  • - No limit on how short or how long the message should be (it would seem ridiculous to send a one line letter to someone in the post, but on email this is acceptable)
  • - Can attach large documents and other files with a click of a button (and without using up resources like paper)
  • - Doesn't use any paper (good for the environment)
Disadvantage

  •  Less social contact with people (social skills won't be as well developed)
  • - Less hand-writing practice
  • - Can be bad for your eyes if you spend too long sending e-mails on your computer
  • - Messages may be misinterpreted easily
  • - Abbreviated language may become common practice for some people
  • - Can provide an easy way to spread viruses to computers
  • - Can be easy to make a "typo" and say the wrong thing, or send the email to the wrong person
  • - Access to a computer and the internet is necessary, and this may not be convenient for all people
