COMPETENCY BASED LEARNING MATERIALS

INTRODUCTION

Welcome to the learner’s guide for the Module in Performing Computer Operations. This learner’s guide contains training materials and activities for you to complete in 102 Hours.

The unit of competency Perform Computer Operations contains knowledge, skills and attitudes required for a DATA ENCODER or a COMPUTER OPERATOR. It is one of the COMMON competencies in Computer Hardware Servicing NC II program.

You are required to go through a series of learning activities in order to complete each of the learning outcomes of the whole module. In each learning outcome there are Information Sheets, Operation Sheets and Job Sheets for further reading to help you better understand the required activities. Follow these activities on your own and answer the Self-Check at the end of each learning outcome. If you have questions, please don’t hesitate to ask your instructor or facilitator for assistance.

Recognition of Prior Learning (RPL)

You may already have some of the knowledge and skills covered in this learner’s guide because you have:

o been working for some timeo Already have completed training in this area.

If you can demonstrate to your trainer that you are competent in a particular skill or skills, talk to him/her about having them formally recognized so you don’t have to do the same training again.

If you have a qualification or Certificate of Competency from previous training, show it to your trainer. If the skills you acquired are still current and relevant to this module, they may become part of the evidence you can present for RPL. If you are not sure about the currency of your skills, discuss it with your trainer or facilitator.

After completing this module ask your trainer to assess your competency. Result of your assessment will be recorded in your competency profile. All the learning activities are designed for you to complete at your own pace.

HOW TO USE THIS MODULE

This competency based learning material (CBLM) contains information and suggested learning activities on Computer Hardware Servicing. It includes training materials and activities for you to complete in 102 hours.

Completion of this module will help you better understand the succeeding module on Computer Hardware Servicing.

This learning module consists of ten (10) learning outcomes. Each learning outcome contains learning activities supported by each instruction sheets. Before you perform the instructions read the information sheets and answer the self-check and activities provided to as certain to yourself and your instructor that you have acquired the knowledge necessary to perform the skill portion of the particular learning outcome.

Upon completion of this learning module, report to your instructor for assessment to check your achievement of knowledge and skills requirement of this learning module. If you pass the assessment, you will be given a certificate of completion.

The following are your guides for completing this learning material, to wit:

Talk to your trainer and agree on how you will both organize the Training of this unit. Read through the learning guide carefully. It is divided into sections which cover all the skills and knowledge you need to successfully complete in this module.

Work through all the information and complete the activities in each section. Read information sheets and complete the self-check. Suggested references are included to supplement the materials provided in this module.

Most probably your trainer will also be your supervisor or manager. He/she is there to support you and show you the correct way to do thing. Ask for help if you need it so.

Your trainer will tell you about the important things you need to consider when you are completing activities and it is important that you listen and take notes.

COMPETENCY BASED LEARNING MATERIALS You will be given plenty of opportunity to ask questions and practice on

the job. Make sure you practice your new skills during regular work shifts. This way you will improve both your speed and memory and also your confidence.

Talk to more experience workmates and ask for their guidance.

Use the self-check questions at the end of each section to test your own progress.

When you are ready, ask your trainer to watch you perform the activities outline in the learning guide.

As you work through the activities, ask for written feedback on your progress. Your trainer keeps feedback/pre-assessment reports for this reason. When you have successfully completed each element, ask your trainer to mark on the reports that you are ready for assessment.

When you have completed this module (or several modules), and feel confident that you have had sufficient practice, your trainer will arrange an appointment with registered assessor to assess you. If you found competent, you will get a National Certificate for this trade.

Computer Errors

A software bug is the common term used to describe an error, flaw, mistake, failure, or fault in a computer program or system that produces an incorrect or unexpected result, or causes it to behave in unintended ways. Most bugs arise from mistakes and errors made by people in either a program's source code or its design, and a few are caused by compilers producing incorrect code. A program that contains a large number of bugs, and/or bugs that seriously interfere with its functionality, is said to be buggy. Reports detailing bugs in a program are commonly known as bug reports, fault reports, problem reports, trouble reports, change requests, and so forth.

An error message is information displayed when an unexpected condition occurs, usually on a computer or other device. On modern operating systems with graphical user interfaces, error messages are often displayed using dialog boxes. Error messages are used when user intervention is required, to indicate that a desired operation has failed, or to relay important warnings (such as warning a computer user that they are almost out of hard disk space). Error messages are seen widely throughout computing, and are part of every operating system or computer hardware device. Proper design of error messages is an important topic in usability and other fields of human–computer interaction.

Common error messages

The following error messages are commonly seen by modern computer users:

Access denied

This error occurs if the user has insufficient privileges to a file, or if it has been locked by some program or user.

The Blue Screen of Death

On Microsoft Windows operating systems, this screen appears when Windows can no longer run because of a severe error. It is roughly analogous to a kernel panic on Unix or Mac OS X.

The Blue Screen of Death (also called BSoD, Blue Screen, or bluescreen), known officially as a Stop Error or a bug check, is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash." The term is named after the color of the screen generated by the error. In UNIX-based operating systems, a similar term is kernel panic.

Stop errors are usually hardware or driver related, causing the computer to stop responding in order to prevent damage to the hardware, whereupon, in the latest versions of Windows, the screen presents information for diagnostic purposes that were collected as the operating system performed a bug check.

The device is not ready

This error most often occurs when there is no floppy disk (or a bad disk) in the disk drive and the system tries to perform tasks involving this disk.

File not found

The file concerned may have been damaged, moved, deleted, or a bug may have caused the error.

Low Disk Space

This error occurs when the hard drive is full. To fix this, the user should close some programs (to free swap file usage) and delete some files

BENJAMIN V. BAUTISTA, SR. – MANPOWER TRAINING CENTER2nd Floor Public Market Building, Poblacion, Malita, Davao del Sur

COMPETENCY BASED LEARNING MATERIALS(normally temporary files, or other files after they have been backed up), or get a bigger hard drive.

Out of memory

This error occurs when the system has run out of memory or tries to load a file too large to store in RAM. The fix is to close some programs, or install more memory.

Different types of error beeps from the system speaker

If you find that there is no system display after power on, you can define the problem, depending on the number of audio signals from the next table.
