Lesson5Using Browser to LocateInformationWhat’s InIn the early age, researching of information is quite hard andchallenging. You need to locate the book and the author name in order toresearch in the library. Today locating information is being made easy. In justone click, you can see many options to choose from the same topic.How do you think using computer browser make locating informationeasier?What’s NewCan you name the different browsers? Try to identify four (4) otherbrowsers in the World Wide Web. Write your answers in your notebook.1. Google Chrome2.3.4.5.What is ItWeb Browser and World Wide WebWeb Browsers are software installed on your PC. On the Web, when younavigate through pages of information, this is commonly known as webbrowsing or web surfing.
Sir Tim Berners-Lee is a British computer scientist. He invented theWorld Wide Web in October 1990. He wrote the first web page editor/browserwhich is WorldWideWeb.app and the first server which httpd. The first webpage was served on the open internet by the end of 1990.It was in the year 1993 that CERN, a European Organization for NuclearResearch, where Sir Tim was working, to announced the global wave ofcreativity, collaboration and innovation.In 1994, Sir Tim moved to Massachusetts Institute of Technology tofound the World Wide Web Consortium (W3C), an international communitydevoted to developing open web standards. He remains the Director of W3Cto this day.Parts of Web browser: HyperText Markup Language (HTML) - This is the markup or format languagefor the web. Uniform Resource Identifier (URI) - A kind of “address” that is unique andused to identify to each resource on the web. It is also commonly calleda URL. Hypertext Transfer Protocol (HTTP) - Allows for the retrieval of linkedresources from across the web.Web Browser TypesInternet ExplorerInternet Explorer (IE) is a product from software giantMicrosoft. This is the most commonly used browser in the universe.This was introduced in 1995 along with Windows 95 launch and ithas passed Netscape popularity in 1998.Google ChromeThis web browser is developed by Google and its beta versionwas first released on September 2, 2008 for Microsoft Windows.Today, chrome is known to be one of the most popular web browserwith its global share of more than 50%.Mozilla FirefoxFirefox is a new browser derived from Mozilla. It was releasedin 2004 and has grown to be the second most popular browser onthe Internet.
SafariSafari is a web browser developed by Apple Inc. and includedin Mac OS X. It was first released as a public beta in January 2003.Safari has very good support for latest technologies like XHTML,CSS2 etc.OperaOpera is smaller and faster than most other browsers, yet itis full- featured. Fast, user-friendly, with keyboard interface,multiple windows, zoom functions, and more.What’s MoreIn this activity, identify the owner or company of the followingbrowser images.

What I Have LearnedBelow are some important concepts regarding the previous lesson. Addanother item to show what you have learned from the lesson. Write youranswer in your notebook.1. World Wide Web is called as WEB. It is an information system on theInternet which allows documents or pages to be connected to otherdocuments using hypertext links, which enable the user to search forinformation or data by moving from one document to another.2. HyperText Markup Language (HTML). This is the markup (formatting)language for the web.3. Uniform Resource Identifier (URI).

If you don’t have them, please ask assistancethrough call to any relative who can assist you. However, if the first twooptions are still difficult to do, you may perform this activity later when thehealth advisories will allow for face-to-face classes.)1.2.3.4.What browser did you use in locating the information?What website location did you click? What is the URL of the site?What copyright year and name of the website?Copy one paragraph about computer maintenance on the site that youvisit.
Lesson6Basic ComputerMaintenanceWhat’s InDo you own any device? What do you do to keep it working? In thislesson, you will learn how to take care of computers.What’s NewQuick CheckCopy the worksheet below in your notebook and check thecorresponding column for the status of your knowledge on basic computermaintenance.STATUSAREAI have no ideaI have a littleI can performabout this.knowledge on this.this task.1. Anti-Spyware Program2. Anti-Virus Program3. System MaintenanceWhat is ItMaintenance of Computer SystemPerhaps you have handpicked the finest computer with the selectedfastest processor and graphic card and with a few gigabytes of memory. So,you thought to yourself that your machine is probably going to sustain youfor the next five (5) years. But little did you discover that some six monthsdown the road, your computer is behaving like a Pentium computer,perpetually flustering you with its choppy images, frustrating pop-ups andtremendously slow disk access. Gradually, your computer crashes and allyour data is lost on one fine afternoon.
One thing you have probably missed out is the need for systemmaintenance. The basic routine maintenance comprises of the 3 basicprocesses: data backup, malware maintenance and disk or file maintenance.Data BackupBacking up basically means creating aredundant copy of a data so that in caseanything happens to the original data, youhave a spare copy. This is typically a simplething to do.What data should I back up?In general, you should back up any work or data that cannot bereplaced easily. Some examples are word processing documents,spreadsheets, databases (for financial data), customer data, and personal filessuch as pictures, music files, emails, etc. As a rule of thumb, do not backupprograms or system folders. Programs will need to be reinstalled before youcan run them and system folders can be restored from your operating systeminstall disc. Be sure to save program installation discs, operating systemdiscs, and registration information in a safe place. If you have downloadedany of your applications, you should save the install files whenever possible.Malware MaintenanceMalware refers to any kind of malicious codes, objects or content thatinfiltrates your computer, resulting in damage and causing your system toact in an undesirable manner. Commonly, these include viruses, spyware,worms, trojan horses, spams and many more. When you are infected, you canlose your privacy, confidential data, and access to your system when softwareand hardware are damaged. Fortunately, there are a couple of preventivemeasures you can take to protect yourself from malware.One thing you can do to scan the file for anyvirus infection before you attempt to open it. If thescan shows nothing, it is probably a safe file. Butthen again, it may be a new virus yet to be updatedin your virus scan. You can either wait and apply thenext virus signature update and perform a secondscan or risk it all and open the file.Disk MaintenanceDid anyone tell you that your hard disk is a trickymachine? When you first installed your operating system,you may be pleased to know how smooth and efficient yoursoftware applications are running. But gradually, it slowsdown and this bothers you. What truly causes the declinein performance? This has much to do with the way youoperate on your system.To do disk maintenance, uninstall any unnecessary software anddefragment your disk. Typically, your system performance will decline whenthe amount of data in your hard disk starts to grow.
