COMPUTER HARDWARE SERVICING NC II BASIC ELECTRONICS: FAMILIARIZING THE RESISTANCE

Resistance

            Resistance is the measure of how difficult it is for current to flow through something.  And being familiar with resistance, it can help you better understand electronic circuitry. Resistance deals also with current that involves in voltage and with the conductors and insulators. Insulators are those do not easily carry a current  like glass, ceramics, woods,  and plastics. For best result in resistance study, Good Conductors is the one to deal with. Metal is the good conductor that I am talking about. Current can easily flows trhough metals that’s why plastics is used as cover for metal wires to be its insulator. Now how about the Silicon and Germanium? They are called “the semi-conductors”  which fall between conductor and insulator.

Computer Hardwrae Servicing NC II Basic Electronics: Familiarizing the Voltage

Voltage

             To understand what electronics is, you need to know first, what is voltage. All we know that if there is no Voltage, electronics is non sense.  Yet, we know all about this, if not , this article can help you.

Let us say I have a battery in my hand. Does the battery have voltage? Yes, it has. The batteries have voltage between its terminals. This voltage helps the Current to flow through any electrical circuit placed across it. If there is a current flow into the circuit, you will see some happenings like a bulb produce light, you can create heat, sound, movement, magnetism, sparks and etc.

Top 10 PC Optimization Technique for Old Computers

                 Optimization helps you to speed up your computer. If your computer is well optimized you can do many things without interruption. It can make your work be easy most specially in typing jobs or any related work. More of us wants to have a high end computer but not affordable with our budget. That's why we are still making sense of our old computer or let us say not a high end one like P4, PM and Sempron processor inside the system unit and only having 512 MB of RAM. What I want to say is, there is a way on how to optimize computer/PC without upgrading. Office works, is what I meant, for what I have in the said old computer. Not only for that, also with the students who cannot afford to buy a new one. Listed below are the ways on how you can optimize your PC without upgrading.

Best Understanding and Identifying about RAM (Random Access Memory)

(Useful Term for Student of Computer Hardware Servicing NC II)

                   RAM (Random Access memory) basically known as the Computer Memory or Computer Data Storage. It allows keep information to be accessed in terribly nearly an equivalent quantity of your time for any storage location, thus information is accessed quickly in any random order.

                   There are two main types or forms of RAM; the SRAM (Static RAM) and DRAM (Dynamic RAM). SRAM is a  form of RAM that is costlier to provide, however is usually quicker and needs less power than DRAM and, in trendy computers, is usually used as cache memory for the electronic equipment While DRAM stores a bit of data using a transistor and capacitor pair, which together comprise a memory cell.
