CO_Q0_ICT8_Module2 What is It The computer as we know it today has its beginning with a 19th Century English Mathematics Professor name Charles Babbage. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. Generally speaking, computers can be classified into three generations. Each generation lasted for a certain period of time and gave us either a new and improved computer or an improvement to the existing computer. Computer Defined Computer is an electronic device that stores, retrieves, and processes data. It can be programmed with instructions. It is composed of hardware and software, and can exist in a variety of sizes and configurations. Computer Organization The block diagram of computer is shown. The computer performs basically five major operations of functions irrespective of their size and model. These are: 1) accepting data or instruction by way of input, 2) storing data, 3) processing data as required by the user, 4) giving results in the form of output, and 5) controlling all operations inside a computer. 1. Input: This is the process of entering data and programs into the computer system. 2. Control Unit (CU): The process of input, output, processing, and storage is performed under the supervision of a unit called “Control Unit”. It decides when to start receiving data, when to stop it, where to store data, etc. 3. Memory Unit: Computer is used to store data and instructions. Figure 1. Block Diagram of a Computer Memory Unit Control Unit Input Unit Output Unit Arithmetic Logic Unit 6
CO_Q0_ICT8_Module2 4. Arithmetic Logic Unit (ALU): The major operations performed by the ALU are addition, subtraction, multiplication, division, logic, and comparison. 5. Output: This is the process of producing results from the data for getting useful information. The ALU and the CU of a computer system are jointly known as the Central Processing Unit (CPU). You may call CPU as the brain of any computer system. Computer Hardware Computer hardware refers to all the physical parts of a computer system. This includes the keyboard, monitor, mouse, and internal parts of the system unit. The main components of the computer hardware are input devices, output devices, system unit, and storage devices. Computer Software Software is a set of programs designed to perform a welldefined function. A program is a sequence of instructions. There are two basic types of software: the system software and application software. System Software System software is a collection of programs that directs a computer’s processor to perform specific functions. It serves as the interface between hardware and users. It includes the operating system, device drivers, and utilities. Operating System An operating system is the most important software that runs on a computer. It manages the computer's memory, processes, and all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's language. Without an operating system, a computer is useless. Examples of Operating System are: Mac OS, Linux, and Windows Occupational Health and Safety Occupational Health and Safety (OHS) is a planned system of working to prevent illness and injury where you work by recognizing and identifying hazards and risks. Health and Safety procedure is the responsibility of all persons in the computer and technology industries. There are three steps used to manage health and safety at work: 1. Hazard Identification (Spot the Hazard) 2. Risk Assessment (Assess the Risk) 3. Risk Control (Make the Changes) 7
CO_Q0_ICT8_Module2 Safety Tips in Performing Computer-related Tasks Tips to avoid muscle, eyes, and joint problems Sit at an adjustable desk specially working with computers. Position the computer monitor (screen) either at the eye level or slightly lower. Put your keyboard at a height that lets your elbows rest comfortably at your sides. Your forearms should be roughly parallel with the floor and should be at the level of the keyboard. Place your mouse at the same height as your keyboard. Make sure your main source of light (such as a window) is not facing directly onto the computer screen. Tilt the screen slightly to avoid reflections or glare. Make sure the screen is not too close to your face. Use Personal Protective Equipment (PPE) during hands on computer hardware tasks. Things to remember: Working at a computer can cause back, neck and shoulder pains, headache, eyestrain and overuse injuries of the arms and hands which can be avoided by following the simple reminders below: Help avoid computer-related injuries with proper furniture, better posture, and good working habits. Put sensible time limits on computer use and video-gaming. Take regular breaks from using a computer and should do some physical activities each day. Ways to Protect your Personal Computers We know that computers are very essential today especially when you are working daily with a computer related activities. Below are some of the symptoms of a computer virus and how to protect your computer. Symptoms of a computer virus: Your computer may be infected if you recognize any of these malware symptoms: slow computer performance erratic computer behavior unexplained data loss frequent computer crashes Preventing computer malwares: Use antivirus protection and a firewall. Get antispyware software. 8
CO_Q0_ICT8_Module2 Always keep your antivirus protection and antispyware software updated. Update your operating system regularly. Increase your browser security settings. Avoid questionable websites. Only download software from sites you trust. Carefully evaluate free software and file-sharing applications before downloading them. Practice safe email protocols: Avoid opening messages from unknown senders. Immediately delete suspected spam messages. 9
CO_Q0_ICT8_Module2 Lesson 2 Inputting Data into Computer System Inputting Data into Computer The process of entering data and instructions into the computer system is called inputting. Input can take a variety of forms; from commands you enter from the keyboard to data from another computer or device. A device that feeds data into a computer such as keyboard or mouse is called an input device. Other data processing software includes: Personal Productivity Software enhances its user’s performance on a specific range of common task. This software supports database management and analysis, authoring and presenting, activity and notes tracking. Electronic Spreadsheet are programs that are used for analysis, planning, and modeling. They provide electronic replacement for more traditional tools such as paper worksheets, pencils, and calculators. In a worksheet of rows and columns are stored in the computer’s memory and displayed on the video screen. Data and formula are entered into the worksheet and the computer performs the calculations based on the formulas entered. Database Management facilitates the storage, maintenance, and utilization of data in a database that is shared by many users. Microcomputer DBMs enables the users to: create and maintain database query a database with a query language Word Processing are programs that computerize the creation, edition, and printing of documents by electronically processing text data. It is an important application of office automation and the most common personal computer application. Desktop Publishing is a software to produce their own printed materials like newspapers, brochures, manuals and books with several type styles, graphics, and color on each page. 10
CO_Q0_ICT8_Module2 Without user input, a computer simply takes up desktop space and waits for directions. Without input, methods and devices, your correspondence, reports, images and numbers remain in your head rather than becoming work in progress. Your computer may accept input from different types of input devices like keyboard and mouse. Creating a document in Microsoft Word Application 1. Click the Microsoft Word Icon 2. Select New. The New Document dialog box appears. 3. Click Blank document. Keyboard Mouse Desktop Taskbar 11

The processor processes the commands when it is being executed. A process has at least one thread execution and might have more than one. Each of those threads will have state as well, which is part of the process state and therefore part of the process. Check the Accuracy of Information When getting information from any sources, it is important to evaluate first the information in order to make it reliable. There are things to consider in evaluating the information. Currency pertains to the timeliness of information. Some questions you may ask to yourself before considering the currency of information are: When was the information published or posted? Has the information been revised or updated? Does your topic require current information or older sources work as well? Input (Input Devices) Output (Output Devices) Process (CPU) Store (Storage Devices) Figure 1. Computer Operation 12
CO_Q0_ICT8_Module2 Relevance refers to the importance of the information to your need or how it relates to your topic. Authority is a source of information. There are some sources that are not authorized to produce information. In order to prevent yourself from taking false information, be sure to check the author if they are authorized to do so. Accuracy is the reliability, truthfulness, and correctness of the content. Consider it by asking yourself some of these questions. Is the information supported by evidence? Can you verify the information in other sources or from your personal knowledge? Purpose – The reason the information exists. What is the purpose of the information? Is the information produced to inform, teach, sell, entertain or persuade? Do the authors make their intentions or purpose clear? Storing the Data The last phase in the computer operation is the storing of data. This is the process in which you will be saving your data for future use. To store it, you need to have a data storage device. Examples of Data Storage Devices are as follows: * Hard Drive Disk * USB Flash Drive * Floppy Disk * Secure Digital Card (SD Card) * Tape * Solid State Drive (SSD) Steps in Saving a New Document 1. Click ‘File’ 2. Click ‘Save’ 3. Pick or Browse to a folder and type a name of your document in the File name box. 4. Click ‘Save’ 13
CO_Q0_ICT8_Module2 Steps in Printing a Document After saving the document, you might need to print it as your output. Follow the steps below on how to print a document. 1. Press Ctr+P or Click on ‘File’ button. 2. Click ‘Print’ button. 3. Select the printer where you want to print your document. 4. Click ‘Print’ button to print the document. 14
CO_Q0_ICT8_Module2 Output Data Any information that is processed by and sent out from a computer or other electronic device is considered an output. It can be text, graphics, tactile, audio and video. An example of an output is anything viewed on your computer monitor screen, such as the words you type on your keyboard. Sample output devices include monitor, printer, graphic output devices, plotters, speakers, etc. There are many different file formats as there are different programs to process the files. A few of the most common file formats are: Word document (.doc or .docx) Excel document (.xls or.xlsx) PowerPoint document (.ppt or .pptx) Webpage images (.jpg, .gif and others) Executable programs (.exe) Multimedia files (.mp3, .mp4, .avi, and others) Performing Works within Ergonomic Guidelines When working on with the computer, ergonomic guidelines must be observed all the time to prevent you from any risks. Here are some of the ergonomic guidelines to follow: 1. Always work in neutral posture. good upper body posture (shoulders back but relaxed) feet firmly on a surface for support (floor/footrest) knees at an angle greater than (>) 90 degrees (Angle behind the knees should be open. Do not seat with the legs tucked under the chair.) back supported by chair head balanced on neck upper arms close to body and relaxed 2. Organize a normal work area. Organizing a normal work means keeping your area suitable and free from disturbance and risks. Take away those unnecessary things within your area so that you can work freely. 3. Check the computer screen position. The computer screen must be positioned properly so that you can comfortably view the screen without having the noticeably tilt. Monitor Printer Speaker 15
CO_Q0_ICT8_Module2 Lesson 3 Accessing Information Using Computer Application Software Application software (app for short) is a program or group of programs designed for end users. Applications may be bundled with the computer and its system software or can be downloaded/purchased separately. It can also be coded as proprietary, open-source or university projects. Different Types of Application Software Computer application software is basically programs and procedures intended to perform specific tasks on a system. There are different types of application software from the lowest level assembly languages to the high-level languages as seen below. Word Processing Software allows the user to create, edit, and print documents. It enables you to write text, display it on screen, store it electronically and modify it by entering commands and characters from the keyboard and print it. Database Software is a utility or software program developed to create, edit, store, search, extract, automate, and maintain database files and records. Application Software Type Examples Word Processing Software MS Word, WordPad, and Notepad Database Software Oracle, MS Access, etc. Spreadsheet Software Apple Numbers, Microsoft Excel Multimedia Software Real Player, VLC Media Player Presentation Software Microsoft PowerPoint, Keynotes Enterprise Software Customer Relationship Management System Information Worker Software Documentation tools, Resource Management Tools Educational Software Encarta, Google Earth Simulation Software Flight and Scientific Simulators Content Access Software Google Chrome, Mozilla Firefox Application Suites OpenOffice, Microsoft Office 16
CO_Q0_ICT8_Module2 Spreadsheet Software is an application capable of organizing, storing and analyzing data in a tabular form. The application can provide digital simulation of paper accounting worksheets. Multimedia Software allows user to create image, audio, video and etc. It was developed to create new multimedia content and enhance the visual and auditory features of already existing material. Presentation Software is used to display information in the form of a slideshow. It has three major functions: an editor that allows text to be inserted and formatted, a method for inserting and manipulating graphic images, and a slideshow system to display the content. Enterprise Software is used to satisfy the needs of an organization rather that individual users. Such organization includes businesses, schools, internet-based user groups, clubs, charities, and governments. Information Worker Software addresses the needs of individuals to create and manage information, often for individual projects within a department. Educational Software is made for educational purposes. It encompasses different ranges from language learning software to classroom management. Simulation Software is based on the process of modelling a real phenomenon with a set of mathematical formulas. It is essentially a program that allows the user to observe an operation through simulation without performing that operation. Content Access Software is used primarily to access content without editing but include software that allows content editing. Such software addresses the needs of individuals and groups to consume digital entertainment and published digital content. Application Suites is a collection of computer programs usually application software or programming software of related functionality, often sharing a similar user interface and the ability to easily exchange data with each other. Application Software Installation Some application software are pre-installed in the computer upon purchase so there is no need for this software to be installed manually. However, for applications that are not installed yet, you need to have an installer. You may obtain the installer by downloading it from the internet through the official website or via disc. Application software installers are usually an executable file with (.exe) file extension. Once the installer is downloaded, you can install the application in your computer. Below are the steps on how to install application software. 1. Download the installer from its official website. 2. Once you have the installer, you may double click it or right click using your mouse and then click on ‘Run as Administrator’. See figure below. 17
CO_Q0_ICT8_Module2 3. After clicking the ‘Run as Administrator’, a pop-up window will appear asking you to install the application. Click ‘Install Now’. 4. There are applications that need product key. When prompted, enter the product key. 5. Wait for the installation to finish. 6. Once finished, a window will prompt. Just click on the ‘Close’ button. Using the Application Once the application is installed in the computer, it is now available for use anytime. Usually, an application icon is placed in your desktop screen. See figure below. 18
CO_Q0_ICT8_Module2 There are also applications that will not be automatically placed on your desktop screen. Just click on the magnifying glass icon on the bottom left-hand corner of your screen to search for the application. Click on the application to run. See figure below. Different Components of a Desktop Screen The main components of the desktop are the icons on it and the panel at the bottom of the screen. Desktop icons represent files, directories, applications, functions, and removable media like CDs or DVDs. The desktop has the following icons by default. Trash/ Recycle Bin contains files and folders that have been deleted. My Computer displays information about hardware network status, operating system, hard disks, common folders and removable devices. Main Menu is a well-ordered structure for accessing the main application. It also contains menu items for major functions like logging out or searching for applications. Taskbar by default, displays all started applications and open windows which allows you to access any application regardless of the currently active desktop. System Tray is the right most part of the panel usually holds the system clock, date, volume control, internet icon, battery status (for laptop) and managing notifications. Notification area displays the programs running in the background and information. My Computer Trash Main Menu Taskbar System Tray Notification Area 19
CO_Q0_ICT8_Module2 Keyboard Techniques with Operational Health and Safety Requirements In order to develop optimal keyboarding speed and accuracy, you need to use proper technique. Not only does proper keyboarding technique help develop skill, but it also helps prevent the development of RSI (repetitive stress injury, more commonly known as carpal tunnel). Correct keyboarding technique requires proper hand positioning at the computer keyboard and learning to key by touch, thus enabling eyes to remain on the copy rather than watching fingers. Correct Keyboard Techniques: Position feet on floor for balance (don’t cross). Center body to the “H” key with elbows at sides. Sit up straight. Adjust chair so you are a “hand span” away from edge of keyboard. Curve finger over the home key. Keep wrists of the keyboard. Keep eyes on printed copy. Key by touch. Key with a smooth rhythm. Correct Hand Positioning on Keyboard The fingers on your left hand should be placed over the A, S, D, and F keys and the fingers on your right hand should be placed over the J, K, L and ; keys. Your thumbs should either be in the air or touching the spacebar key very lightly. A S D F J K L ; SPACE BAR 20
