How To Operate a Laptop Computer



   The proper operation of a laptop computer ensures that the laptop not only works properly but also protects the user from any injury or harm. Improper ways of operating a laptop computer and not following the prescribed operating procedures and safety issues can lead to irreparable damage to the laptop computer. An improperly operated laptop can also cause injury to the user such as a laptop burn. A laptop computer has different operational needs as compared with a desktop computer hence should be handled and managed in a more delicate manner as that of desktop computers. 

Materials Needed:
- Laptop Computer
- Internet
Step 1
   The laptop computer has to be shut down whenever it is not in use to prevent it from overheating. Every laptop user must remember that laptop computers generally warm up faster than desktop computers. To help the laptop computer avoid overheating when not in use even for short durations, the user may make adjustments on the power options provided in the laptop computer. The user can program the hard drive and display to turn off after preset time duration. Another option for the user is to set the computer into hibernate or standby mode.
Step 2
   The user should shut down the computer before placing the laptop in its carrying bag since the laptop can melt when left on, particularly when the notebook is placed in a container where no air or limited air is allowed to circulate.
Step 3
    The laptop’s air vents must also be periodically inspected and cleaned to keep these air vents free from debris. However, the user must not force anything into the air vents to clean its inside as this may cause damage to the laptop computer. The laptop fan should also be checked since an improperly working laptop fan can be a cause for overheating. To test the laptop fan, the user may download the software from the laptop manufacturer’s website or online support. In some cases where the laptop fans are controlled through BIOS, the user may check online from the manufacturer’s website for any BIOS updates.
Step 4
    The user must also ensure that the laptop is operated on a hard surface and preferably one that provides ventilation. Users are not advised to use a soft material between the user and the laptop since soft materials can block the flow of air and thus create overheating. A heat sink base could be used if the use of a soft surface is unavoidable.
Step 5
    The user must also unplug any accessories whenever the laptop computer is not in use. These accessories not only consume power but they could also lead to overheating of the laptop.




Independent Laptop Learning Method


Step 1


   Read the laptop user manual. If the laptop did not come with a manual (for example, you purchased a used laptop), you can usually go to the manufacturer's website to download a copy of the manual, or call the manufacturer's Customer Support number to have the manual sent to you.

Step 2


    Orient yourself to the laptop components, switches, battery and peripheral devices, such as the power supply/charger, external mouse, keyboard and speakers. Most manufacturers ship laptops with the battery only partially charged, so you should connect the battery, connect the power supply/charger to the laptop and plug the cord into an electrical outlet.

Step 3


    Power on the laptop and customize the settings. If your laptop is new, you will be prompted to register your operating system, create a user account and configure your system preferences and settings. If your laptop is used, log into an existing account and configure the settings.

Step 4


    Open a text editing or word processing program to practice typing on the laptop keyboard. You might have initial difficulty adjusting to the smaller size of a laptop, and some keys (directional arrows, delete, escape, or NumLock, for example) might not be in the same location as on your desktop keyboard. The faster you learn where the keys are, the more comfortable you will be using your laptop.

Step 5


    Practice opening and closing applications to get a feel for any differences in timing or target disk drive locations for those operations.

Other Laptop Learning Methods


Step 1


     Enroll in a low-cost or free course that teaches basic laptop use. Such courses are often available at local community centers, junior colleges and libraries.

Step 2


    Follow a video tutorial that teaches basic laptop use. Laptop tutorials on DVD are available from most computer stores and online retail outlets. You can also select a tutorial from online trainers such as Lynda.com, linked below.

Step 3


     Hire an expert to teach you how to use your laptop. Many computer technicians are available for one-on-one training sessions. You can usually find qualified technicians to assist you through online services such as Crossloop, or computer sales and service organizations such as Best Buy's Geek Squad, linked below.

Introduction of Internet


  The Internet and the World Wide Web, in combination, are a worldwide broadcast medium for the general public. Using your desktop computer, smartphone, tablet, Xbox, media player, GPS, and even your car and home thermostat, you can access a vast world of messaging and content through the Internet and the Web.
  The Internet is a gigantic hardware network. The Internet's biggest readable content is what we call the 'World Wide Web', a collection of several billion pages and images that are joined by hyperlinks. Other content on the Internet includes: email, instant messaging, streaming video, P2P (peer-to-peer) file sharing, and FTP downloading.
  Below is a quick reference to help fill in your knowledge gaps, and get you participating in the Internet and the Web quickly.  All of these Lifewire.com references can be printed, and are free for you to use thanks to our advertisers.
How Is the 'Internet' Different from the 'Web'? The Internet, or 'Net', stands for Interconnection of Computer Networks. ​ It is a massive conglomeration of millions of computers and smartphone devices, all connected by wires and wireless signals. Although it started in the 1960's as a military experiment in communication, the Net evolved into a public free broadcast forum in the 70's and 80's. No single authority owns or controls the Internet.  No single set of laws governs its content.  You connect to the Internet through a private Internet service provider, a public Wi-Fi network, or through your office's network. 
  In 1989, a growing collection of readable content was added to the Internet: the World Wide Web.  The 'Web' is the mass of HTML pages and images that travel through the Internet's hardware.  You will hear the expressions 'Web 1.0', 'Web 2.0', and 'the Invisible Web' to describe these billions of web pages.
  The expressions 'Web' and 'Internet' are used interchangeably by the layperson. This is technically incorrect, as the Web is contained by the Internet. In practice, however, most people don't bother with the distinction.

What Is 'Web 1.0', 'Web 2.0', and 'the Invisible Web'?

     Web 1.0: When the World Wide Web was launched in 1989 by Tim Berners-Lee, it was comprised of just text and simple graphics.  Effectively a collection of electronic brochures, the Web was organized as a simple broadcast-receive format.  We call this simple static format 'Web 1.0'.  Today, millions of web pages are still quite static, and the term Web 1.0 still applies.
     Web 2.0: In the late 1990's, the Web started to go beyond static content, and began offering interactive services.  Instead of just web pages as brochures, the Web began to offer online software where people could perform tasks and receive consumer-type services.  Online banking, video gaming, dating services, stocks tracking, financial planning, graphics editing, home videos, webmail... all of these became regular online Web offerings before the year 2000.  These online services are now referred to as 'Web 2.0'.  Names like Facebook, Flickr, Lavalife, eBay, Digg, and Gmail helped to make Web 2.0 a part of our daily lives.
    The Invisible Web is a third part of World Wide Web.  Technically a subset of Web 2.0, the Invisible Web describes those billions of web pages that are purposely hidden from regular search engines.  These invisible web pages are private-confidential pages  (e.g. personal email, personal banking statements), and web pages generated by specialized databases (e.g. job postings in Cleveland or Seville).   Invisible Web pages are either hidden completely from your casual eyes, or require special search engines to locate. 
    In the 2000's, a cloaked part of the World Wide spawned: the Darknet (aka 'The Dark Web'). This is a private collection of websites that is encrypted to conceal all of the participant's identities, and prevent authorities from tracing people's activities. The Darknet is a black market for traders of illicit goods, and a sanctuary for people who are seeking to communicate away from oppressive governments and dishonest corporations.

Internet Terms that Beginners Should Learn

   There are some technical terms that beginners should learn.  While some Internet technology can be very complex and intimidating, the fundamentals of understanding the Net are quite doable. Some of the basic terms to learn include:
  • HTML and http/https
  • Browser
  • URL
  • ISP
  • Downloading
  • Malware
  • Router
  • E-commerce
  • Bookmark.

Mobile Internet: Smartphones and Laptops

Laptops, netbooks, and smartphones are the devices we use to surf the Net as we travel. Riding on the bus, sitting in a coffee shop, at the library, or in an airport, mobile Internet is a revolutionary convenience. But becoming mobile Internet-enabled does require some basic knowledge of hardware and networking. Definitely consider the following tutorials to get you started:

Email: How It Works

Email is a massive subnetwork inside the Internet.  We trade written messages, along with file attachments, through email. While it can suck away your time, email does provide the business value of maintaining a paper trail for conversations.   If you are new to email, definitely consider some of these tutorials:

Instant Messaging: Faster than Email
Instant messaging, or "IM", is a combination of chat and email. Although often considered a distraction at corporate offices, IM can be a very useful communication tool for both business and social purposes.  For those people that use IM, it can be an excellent communication tool.

Social Networking
"Social Networking" is about starting and maintaining friendship communications through websites. It is the modern digital form of socializing, done through web pages. Users will choose one or more online services that specialize in groupwide-communications, and then gather their friends there to exchange daily greetings and regular messages. Although not the same as face-to-face communications, social networking is immensely popular because it is easy, playful, and quite motivating. Social networking sites can be general, or focused on hobby interests like movies and music.

The Strange Language and Acronyms of Internet Messaging
The world of Internet culture, and Internet messaging, is truly confusing at first. In part influenced by gamers and hobby hackers, conduct expectations do exist on the Net. Also: language and jargon are prevalent. With the help of Lifewire.com, perhaps the culture and language of digital life will be less daunting...

The Best Search Engines for Beginners
With thousands of web pages and files added everyday, the internet and the web are daunting to search. While catalogs like Google and Yahoo! help, what's even more important is the user mindset... how to approach sifting through billions of possible choices to find what you need.

How to create blog


Blog Definition:

A blog (also called a weblog or web log) is a website consisting of entries (also called posts) appearing in reverse chronological order with the most recent entry appearing first (similar in format to a daily journal). Blogs typically include features such as comments and links to increase user interactivity. Blogs are created using specific publishing software.
The World Before Blogging:
  There was a time when the Internet was just an informational tool. In the early life of the World Wide Web some 20 years ago, websites were simple and provided a one-sided conversation. As time went on, the Internet became more interactive with the introduction of transaction-based websites and online shopping, but the online world remained one-sided.
  That all changed with the evolution of Web 2.0 (the social web) wherein user-generated content became an integral part of the online world. Today, users expect websites to provide a two-way conversation and web logs (or blogs) were born.
The Birth of Blogs:
  The earliest blogs started in the late 1990s as online diaries. Individuals posted information on a daily basis about their lives and opinions.
  The daily posts were listed in reverse date order, so readers viewed the most recent post first and scrolled through previous posts. The format provided an ongoing inner monologue from the writer.
  As blogs evolved, interactive features were added to create a two-way conversation. Readers took advantage of features that allowed them to leave comments on blog posts or link to posts on other blogs and websites to further the dialogue.
Blogs Today:
  As the Internet has become more social, blogs have gained in popularity. Today, there are over 100 million blogs with more entering the blogosphere everyday. Blogs have become more than online diaries. In fact, blogging has become an important part of the online and offline worlds with popular bloggers impacting the worlds of politics, business and society with their words.
The Future of Blogs:
   It seems inevitable that blogging will become even more powerful in the future with more people and businesses recognizing the power of bloggers as online influencers. Anyone can start a blog thanks to the simple (and often free) tools readily available online. The question will likely become not, "Why should I start a blog?" but rather, "Why shouldn't I start a blog?"

Connecting to the Internet


1. Set up a connection. In order to connect to the internet, your computer will need to have access to an internet connection. This may come in the form of a wireless network, or you may need to connect your computer directly to your network's router or modem. All of this depends on how the network at your location is configured, and the capabilities of your computer.

  • Connect your computer to a wireless (Wi-Fi) network. If your home, office, or school has a wireless network set up, you can use your computer to connect to it. Most laptops can connect to a wireless network without any fuss, while some desktops will need to have a wireless network card installed.
  • A wired network connection can be faster and more stable. If your computer is physically close to your internet access point (router or modem), you might want to consider using an Ethernet cable to connect your computer to the network. This is much more viable with a desktop, since they are typically immobile. A wired connection will not experience interference like wireless network might, and transmission speeds are much faster.
     
2.Open a web browser. The web browser is the software that allows you to view webpages, watch online videos, download files, and do essentially everything else internet-related. All computers come with a browser installed by default (Internet Explorer on Windows, Safari on Mac, and Firefox on Linux), but there are several popular alternative options.

  • Google Chrome is one of the most popular alternative browsers available, and allows you to connect and sync with your Google account. Chrome is available for free from Google.
  • Firefox is another very popular free browser. It is very customizable and contains a lot of powerful security options.
     
3.Send an email. Emailing is one of the most common forms of communication these days, and knowing how to send an email is now an essential computer skill. You can set up a free email account with a variety of different services, and can be composing an email in just a few minutes.
 
4.Download a file. The internet is chock full of different types of files that you can download to your computer. Popular types of files include images, music, and programs. There are thousands of places to find files to download, and a variety of different ways to do so.




Introduction
   There's almost no limit to what you can do online. The Internet makes it possible to quickly find information, communicate with people around the world, manage your finances, shop from home, listen to music, watch videos, and much, much more. Let's take a look at some of the ways the Internet is most commonly used today.
Finding information online
    With billions of websites online today, there is a lot of information on the Internet. Search engines make this information easier to find. All you have to do is type one or more keywords, and the search engine will look for relevant websites.
   For example, let's say you're looking for a new pair of shoes. You could use a search engine to learn about different types of shoes, get directions to a nearby shoe store, or even find out where to buy them online!
   There are many different search engines you can use, but some of the most popular include Google, Yahoo!, and Bing.
Email
    Short for electronic mail, email is a way to send and receive messages across the Internet. Almost everyone who uses the Internet has their own email account, usually called an email address. This is because you'll need an email address to do just about anything online, from online banking to creating a Facebook account.
Social networking
   Social networking websites are another way to connect and share with your family and friends online. Rather than sharing with just a few people over email, social networks make it easier to connect and share with many people at the same time. Facebook is the world's largest social networking site, with more than 1 billion users worldwide.
Chat and instant messaging
   Chat and instant messaging (IM) are short messages sent and read in real time, allowing you to converse more quickly and easily than email. These are generally used when both (or all) people are online, so your message can be read immediately. By comparison, emails won't be seen until recipients check their inboxes.
   Examples of instant messaging applications include Yahoo Messenger and Google Hangouts. Some sites, like Gmail and Facebook, even allow you to chat within your web browser.
Online media
  There are many sites that allow you to watch videos and listen to music. For example, you can watch millions of videos on YouTube or listen to Internet radio on Pandora. Other services, like Netflix and Hulu, allow you to watch movies and TV shows. And if have a set-top streaming box, you can even watch them directly on your television instead of a computer screen.
Everyday tasks
   You can also use the Internet to complete many everyday tasks and errands. For example, you can manage your bank account, pay your bills, and shop for just about anything. The main advantage here is convenience. Rather than going from place to place, you can do all of these tasks at home!
