Through my experience, passing the TESDA NC II Computer Hardware Servicing Exam is not really difficult as long as you follow these important tips. Be there at TESDA testing center earlier than the scheduled time for exam, eat well and avoid from any destruction. Once the exam started, listen very well on the instructions. Exam is divided into three categories theoretical, computer hardware identification, and practical exam.

Theoretical – is a written exam and it is composed of theories about computers such as computer terminologies, abbreviation, little of mathematical explanation like binaries and a lot more, so start reviewing your notes now. Computer Servicing Exam will also includes Networking Topologies advantages and disadvantages, network type of equipment will also be part on the exam. You must also review about the common types of viruses and how it will infect your computer system applications and operating system. Learning about various types of processors and its specifications is also a high value. You must also learn the BIOS Setup, and configuration, Operating System familiarization and likewise about storage devices. However, for theoretical they give a little weight for this exam since certification for TESDA NC II Computer Hardware Servicing is more focus on technical aspect so you must learn more about identifying parts of computers and its specific functions, as well as on the practical exam. There will be an instance that after the exam a discussion or some sort of interview between you and the examiner will be conducted.

Computer Hardware Identification – practically it is more on identifying computer parts and its function. From my experience, when I took the exam last two years ago they also included older computers to be part of the exam. During this exam you will be ask and explain a certain parts of computer. Computer modular parts are being placed on the table and randomly, the examiner will pick a computer parts and it will presented to you and it will ask you to identify the parts and explain the function of it. So it is really advisable to learn all parts of the computer in order for you to pass the computer hardware servicing exam.  For example; like Computer Mother Board or (MOBO) you need to identify what parts are included in the North Bridge and south bridge of this mother board. There are instances as well that old computer part will be ask to you such as; 8 bit and 16 bit ISA interface riser card, internal modem, com ports and serial ports. You may also ask to enumerate some of the input and output devices. In order to pass the hardware identification exam you must learn also the older parts of computers. One more tips, you might need also to learn about memory module it is possible that you will be ask the differences of various memory module types such as SIMM, DIMM, DRR 1, 2 and the latest is DDR 3. Also, you might learn computer beep error codes this is very important to identify computer hardware errors. Another thing is you need also to learn hard disk jumper settings and its purpose this is typically available on the PATA hard disk drive, this is in line in preparing your hard drive for OS installation.


Practical exam – This is the most exiting part of the computer hardware servicing exam since it is more on hands-on exam or realistic. Here, you will be instructed to disassemble the system unit and identify the various components inside, like Internal Power Supply, you must identify the types of internal power supply weather it is ATX or AT types of power supply. You will be instructed as will to identify the location of Processor and identify what type of processor socket it is, as well as the brand. There are various types of processor sockets for example; Land Grid Array (LGA), Socket A, Slot type and many more. Before you disassemble the system unit you must explain to the examiner the proper way of doing it, that you will need to have an anti-static wrist strap in order not to damage the sensitive electronic components, if this device is not available you just discharge your self by touching the metal parts of the system unit and the other hand is on the grounded wall. Once you have disassemble the computer (please take note that before you disassemble the system unit you need to verify it first if it is working) this will be an additional points to you… to continue you need to placed the dismantled parts on a safe placed with anti static plastic below it. Ensure that all Mounting Screws are properly secured since the examiner is very particular on this. Once you’ve done with the disassembly process you are required to set this up again be sure that once you have assembled the system unit the unit is working as it is. This is very high value when taking the TESDA NC II Computer Hardware Servicing Exam.

After that, you will be instructed to install Windows Operating System particularly Server OS such as Windows 2000 or latest on the server unit. Will, this is only a basic installation just reformat the unit and install specific hardware drivers. After you have successfully installed this application you are then required to setup a local networking which has access to the internet as well. You will be able to setup a small network in the classroom and in your own knowledge you need to connect your internal network to the internet. After you have set this up you will be required to allow folder, and printer sharing in your internal network. Just a simple tips while working on this just ensure that your workgroup is the same to all host PC and assigned proper static IP addresses to your workstations. Since this is only a simple network environment and you don’t need to setup a DHCP server the same workgroup and proper assignment of IP addresses will suffice.

For you to be able to pass the Computer Hardware Servicing TESDA NC II exam you must review all of these. For those experienced computer technicians, this is really easy for you since you are more knowledgeable when it comes to this. However, for the beginner or fresh graduate students I guaranteed that you will greatly pass the written or theoretical exam since these are still fresh in your mind. But, for the hardware identification and practical exam you need to review for it further. In my experience, fresh or newly graduate students who took the exam have less percentage to pass compared to an experienced computer technician. Below are the exam pointers on taking the Computer Hardware Servicing Exam for TESDA NC II.
