Inside a typical CPU

Today's motherboard comes with a built-in S/V/L, wait what an S/V/L. It stand for Sound, Video. and LAN. The only thing missing if your purchasing a new motherboard is the CPU and it cooling system and the memory module which is sold separately. But if your purchasing a whole computer set then that not applicable. Okay lets focus on the motherboard that is found inside every computer. The motherboard is where it all connects. The monitor using its cable is plug into the video card port which is connected or built-in the motherboard. The same is true for the mouse and keyboard, they connects via the PS2 or USB port which is usually built-in into the motherboard. The same is true to all external devices that we can connects to the computer, your Web cam, Mic, Speaker system, your smartphone, printer, scanner, external drive and a host of other devices. The most common port used in interconnection for today devices is the USB port. Your supposed to just plug it in and let it connect to your computer.

Okay where suppose to blog about the external parts not the inside parts, but i thought i should give you a sneak preview of my nest post. Back to the external parts. The CPU Case is also important not just for appearance but also for the cooling system it can provide to your CPU unit. You should know where are those FAN located so would not be able to block them when placing your computer on tight spot. Also it should be strong enough to handle the daily grind that it would experience. The air should be able to get in and out of your CPU Case with the aid of those cooling fan properly positioned in your case design. The CPU is where all the work is done, the input, processing and output is done all in there. Make sure to also check on your CPU regularly so that dust build up and other stuff like small insects should not make your CPU there permanent abode. It should be check regularly, lets say weekly to maintain it in top form.

Computer 101

One may ask a question What is a computer? and the answer to that depends on how do you look at things, the computer, basically it has screen which display the information, it has a keyboard and mouse to access and manipulate this information and a main system unit where all the information is store and process. All this component are link together via cables, all this cable is connect to the main system unit most of the time it is located at the back of the computer.

The computer is one of the most used machine today. It can be found in almost all places in all country of the world today. The reason for this is it been design to carry-out all sort of task man would like it to do.

As i explain earlier the computer is made up of several main keys parts, i say key parts because without them it will not function properly. They are the monitor, system unit, keyboard, pointing devices and printer. Still the other add on parts that has been dim necessary and very useful is the web-cam, microphone and speaker or headset. The function of the the main key part is always been the basic, to input and process the information and create an output of that information.

A computer can do multiple things at once of course this would this would depend on the hardware configuration that the computer has. If the computer will be used for ordinary task such as typing report, watching movies, personal stereo system and playing minor games such as solitaire, then a ready made computer from the shelf is right. But is if the computer will be used for gaming then a higher memory, a faster processor, a bigger hard drive and a separate graphics card will be needed. Please consult and do some planning if your going to buy a new set of computer.

Another function of the computer is to do specific task, one major example of this is a computer is used as an ATM Machine. To function like this a software is used to configure that computer to function as required and an added hardware is added to the exiting computer setup to complete the task. So the computer can be programmed to do also specific task.
