Q2 LESSON 1 - USE OF HAND TOOLS

Toolkit - a set of tools designed to be used together or particular purpose

ACRONYMS

ESD (Electro - Static Discharge)

USB (Universal Serial Bus)

LCD (Liquid Crystal Display)

PROPER TOOL SECTION

TOOL

- a handheld device that aids in accomplishing a task

- range from a traditional metal cutting part of a machine to an element of a computer program that activates and control a particular function.

PREPARING FOR THE TASK

*how do you select the best tool for the job?

FIRST, know and understand in detail the scope of work to be accomplished. SECOND, a plan for the scopes taking into account the sequence of task

*selecting the best tool for each task requires training in the proper use of the tools, field experience in their safe use, and following the manufacturer's guidance and instruction for the specific tool.

* when obtaining the tool all the associated tooling and consumable parts, as recommended by the manufacturer, must be included in ADDITION, related consumable parts must also be selected and used according to their manufacturer's instructions

SAFE USE TOOLS

*Once selected, use the tool for the purpose for which it was designed. Not all tools come with detailed instructions, but there are those that do spell out the safety. DO's and DON'Ts for your safety if there are set-up or use options quarter judgement must always be based on what is the safest way to use the tool.

ENVIRONMENTAL SAFETY AND HEALTH PROGRAM REQUIRES THE FOLLOWING

*All tools be kept in good condition with regular maintenance.                                                                  *The right tool be used for the job.                                                                                                                * Each tool be examined before use AND damage or defective tools NOT to be used                                *Tools be operated according to manufacturer's in structures                                                                      *The right protected equipment for the tool and activity be used  

HARDWARE TOOLS

*To complete hardware repairs, it is important to have a toolkit that should contain all the necessary  tools. As you gain experience, you will learn which tools to have available for different types of jobs

FOUR CATEGORIES OF HARDWARE TOOLS

*Electro - Static Discharge Tool (ESD)                                                                                                        *Hand Tools                                                                                                                                                  *Cleaning Tools                                                                                                                                          *Diagnostic Tools

ELECTRO - STATIC DISCHARGE (ESD) TOOLS

Static Electricity                                                                                                                                             - easily generated by friction on carpet, tile flooring clothing, hair, fabric, and etc. The friction of moving air alone will charge suspended particles  and cause the buildup of static electrical changes on people and objects in the environment. Grounded anti-static work mats used with anti-static wrist straps provide the most basic means for the controlled discharge of electro-static electricity.

 EXAMPLE OF ESD TOOLS

ANTI - STATIC WRIST STRAP                                                                                                                   - used to prevent ESD damage to computer equipment.                                                                               ANTI - STATIC MAT                                                                                                                                   - used to stand or place hardware to prevent static electricity from building up.

HAND TOOLS                                                                                                                                             - device for performing work on a material or a physical system using only hands.                                   - the hand tools can be manually used employing force, or electricity powered, using electrical current.

CLEANING TOOL  

CLEANING TOOL - essential when maintaining or repairing computer. Using these tools ensures that computer components are not damaged during cleaning.

EXAMPLE OF CLEANING TOOLS

LINT - FREE CLOTH - used to clean different computer components without scratching or leaving debris.                                                                                                                                                            COMPRESSED AIR - used to blow away dust and debris from different computer parts without touching the components.                                                                                                                              CABLE TIES - used to bundle neatly inside and the outside of the computer.                                            PARTS ORGANIZER - used to hold screw, jumpers, fasteners and other small parts and prevent then from getting mixed together. 

DIAGNOSTIC TOOLS 

COMPUTERS - are easier to use and more dependable with each new generation of hardware and operating system update but that doesn't mean they're problem free. 

EXAMPLE OF DIANOSTIC TOOLS  

MULTIMETER - used to test the integrity of circuits and the quality or electricity in computer components.                                                                                                                                                  LOOPBACK ADAPTER - used to test the functionality of computer parts.

Q4 LESSON 1 - ASSEMBLY AND DISASSEMBLY

DISASSEMBLY OF PC It is to break down a device into separate parts. A device may be disassembled to help determine as problem, to replace a part, or take the parts and use them in another device or sell them individually. STEP-BY-STEP OF DIASSEMBLY OF A PC   UNPLUGGING . First thing you do is to unplug every cable that is plugged into your computer. That includes the cables such as power, USB, mouse, keyboard, internet, ethernet, modem, etc. Just unplug all the cables for safety purposes. OPENING THE OUTER SHELL/CASE . Unscrew the four screws at the back of the computer. On most computer cases, there will be large knobs that you can unscrew by hand or by screwdriver on the back right side of the computer. The left side has small screws because on that side you can't access much on the inside. Once the screws are removed, you can remove the side panels. REMOVING THE SYSTEM FAN . Unplug the fan from the motherboard. You can find the plug by following the wire from the fan. Next, you ...

Q3 LESSON 3 - NETWORK CABLING

Image
NETWORK CABLES - used to connect and transfer data and information between computers, routers, switches, and storage area networks. These cables are essentially the carrier or media through which data flows.     There are different types of communications cables and the appropriate type to use will depend on the structure and topology of the overall architecture of the system. The most commonly used types of communication cable are dominated by what is referred to as " twisted pair cable ". In local area networks; typically, office environments, retail, and commercial sites, copper communications cabling, i.e., twisted pair cable is by far the most commonly used type of cable. TWISTED PAIR - is used in many ethernet works. Comprising of four pair of thin wires or conductors, these wires or conductors are contained inside of the insulation or outer sheath of the cable. Each pair is twisted into several additional twists. These twists are designed to prevent interference from o...

Q3 LESSON 2 - NETWORK TOPOLOGY

Image
  NETWORK TOPOLOGY - represent the way to connect different computers on network. It comprises of nodes and links. TYPES OF NETWORK TOPOLOGY POINT-TO-POINT - there is a dedicated connection between two ends or devices. It sends or receive signal from exactly one device.  BUS TOPOLOGY - each device is connected through a single cable called backbone of the network. STAR TOPOLGY - this topology no. of devices are linked/connected with a centralized device i.e. Hub or Switch which performs a star shape. RING TOPOLOGY - each device is connected with two other devices to form a ring. TREE TOPOLOGY - this configuration looks like branches of a tree. It is a hybrid topology, combines features of star and bus topologies. MESH TOPOLOGY - each computer and network device is interconnected with one another. It uses point-to-point connection. It is best suited for long distance communication.
