Computer Parts and their Functions

Computer Parts and their Functions

l Housing- The housing is the part of your computer that holds all the parts that make the computer operate. In a desktop tower, the housing does not include a monitor, keyboard or mouse. 

l Motherboard- The motherboard is the part of your computer that wires all of the other parts together. It is a printed circuit board and includes the CPU and memory. Every component of your computer connects directly into the motherboard.

l Processor(CPU)-The processor, or CPU, of a computer is basically the brains of the computer. The processor is responsible for interpreting every code it receives from the other computer components, and making it usable to your operating system.

l Hard Drive - The hard drive part of your computer is also called the hard disk. Essentially, it is the part of the computer that stores your information. If you upload a picture to your computer, it is stored on the hard drive. 

l Display Adapter- Whether a graphic card or part of the motherboard, the display adapter is the component of your computer that interprets video signal. They define how frequently your monitor refreshes, how many colors the display supports and the maximum resolutions.

l RAM (Memory)- Random Access Memory, or RAM, is the part of your computer that is used as instant memory. RAM is always in use as a temporary location to execute instructions from your computer.

l Optical Drive-An optical drive uses light to read and write data. It is the drive you use to burn CDs, DVDs and Blu-Ray discs. Optical drives can be either slot loading, or tray loading and come in many different configurations. Optical drives connect directly to the motherboard of the computer.

Safety Procedures in Using Hand Tools and Equipment

We are already familiar with the different hand tools and their proper use. Know we need to know how to be safe in using these. What are the safety precautions in using hand tools and equipment? What are it’s do’s and don’t’s?

Safety Precautions in Using Hand Tools

and Equipment

1. All tools must be kept in good condition with regular maintenance.

     Always remember to keep hand tools, equipment and paraphernalia clean for better use and organized workplace.

Procedures in Cleaning, Tightening and Simple

Repair for Hand tools, Equipment and Paraphernalia

5. Before cleaning any tool, be sure to wear the proper personal protective equipment (PPE). Gloves, masks and goggles are usually worn when cleaning tools since most cleaning agents and solutions are harmful to the human body.

6. Only use cleaning agents as prescribed by the tool or equipment’s manufacturer. Follow the cleaning procedures as well to make sure that no damage will be inflicted on the tools.

 Malfunction and problems are unavoidable. You can encounter different problems with various solutions.

Common Malfunctions in Hand Tools, Equipment and Paraphernalia

1. Small objects tend to fall down when being held by a gripping tool like pliers. This usually happens when the jaws of the pliers are blunt, thus making it hard to hold on things. This can be prevented by making sure that gripping tools have well maintained jaws that can grasp objects properly.

2. The use of striking tools also imposes a great threat if there will be a malfunction. Common hazards are heads separating away from the handle. This could cause severe injuries to anyone. To avoid this type of accident, the handle of a striking tool must be tightly attached to its head.

3. Power tools also impose danger during mishaps. Common problems are electrical short circuiting or mechanical problems. Malfunctioning power tools may cause electrocution and even decapitation of the limbs. These accidents can be avoided by making sure that all power tools are well maintained and are in fit operating condition.

4. When using a driving tool, screws may slip the tip of the screw driver. This happens when the screw driver is not properly aligned with drive of the screw’s head. This can be minimized by making sure that the tip of the screw driver is well secured in the drive of the screw’s head. Using a screw driver with a magnetized tip can also help minimize this type of malfunction.

Tools in Computer Hardware Servicing

Computer according to Webster is an electronic device that is used for storing and processing data, typically in binary form, according to instructions given to it in a variable program. In these days you can see it everywhere. It has been a part of our student life. We cannot print our assignment without computers. Are you amazed how computer works? What are the tools needed in order for you to maintain your computer?

Tools in Computer Hardware Servicing

1.        Chip Inserter with Pin Straightener - designed to insert a DIP chip into a circuit board.

2.      Chip Extractor - used to remove chips from regular (non-ZIF) sockets, but modern PCs do not generally use these sockets any more. It is useful for upgrading much older systems in some cases.

3.      Three Prong Parts Retriever - used to retrieve screws, although is also helpful in retrieving jammed bits in the motherboard.

4.      Assembly Tweezers - used for picking up and manipulating objects too small to be easily handled with human hand.

5.      Slotted Screwdriver – 1/8″, 3/16″, 1/4″, #1,#2 & #0 - It is a good screwdriver with magnetic, interchangeable bits and a comfortable handle. The magnetic tip will prevent screws falling into the PC, and will let you get access to drives mounted deep in your system case.

6.      Nut Driver 3/16″ - really important one because this is the size of nut most commonly used on PCs. These hexagonal nuts are used as mounting hardware for motherboards and serial and parallel ports.

7.      Nut Driver 1/4″ - It allows one to use a single handle with a number of sizes instead of having a separate nut driver for each size.

8.      Torx Screwdriver or Bits - star-shaped screwdriver heads that are used to make equipment “tamper-proof”.

9.      Long Nose Plier - can help to cut wires and they can get in and out of tight spots, unlike regular pliers.

10.  Needle Nose Tweezer - These are useful for grasping small items and for removing and replacing jumpers on circuit boards.

11.  Spare Part Tube - These handy parts tubes is use to hold extra computer screws, nuts and washers.

12.  Soldering Iron - It is essential for repairing circuit boards but seldom being used and it is quite dangerous for improper use.

13.  8″ Wire Cutter/Stripper - It is for wire cutting and stripping insulation on single, multiple and fine stranded wire cables with plastic or rubber insulation.

14.  6″ Adjustable Wrench - It is a spanner with a “jaw” of adjustable width which allow it to be used with different sizes of fastener head (nut, bolt etc.) rather than just one fastener, as with a conventional fixed spanner.

15.  Parts organizer: Used to hold screws, jumpers, fasteners, and other small parts and prevents them from getting mixed together
