Can You Tell Me The Inside Parts Of A Computer System?

Computer systems consist of two kinds of components, one is the harware and the other is the software. As far as the inside of the computer is concerned, it consists of several parts containing mother board, RAM, secondary devices and several cards.

Computer technology growing very fast and much new and faster technology
came into this industry, but the main inside Hardware components are basically same.
However there brand, design, quality have changed.

• Ports
• Memory
• CPU (Central Processing
       Unit)
• Hard drive
• Optical Graphics card
• drive
• Sound system
• Lights
• PSU Motherboard
• (Power Supply Unit)

Ok, you say 'List the inside parts of a computer'... There's a problem with answering your question directly, as computers can be wildly different in quality as well as number of components...

1st, and outermost is the case itself. As I'm sure you're aware, these can vary EXTREMELY widely, from paint jobs to extra ports, to overall size, to external gages for reading internal temperatures, to even digital readouts for current processor load, and memory use.

2nd, The largest circuit board inside the case to which all other connections attach (or at least the board they attach to is connected to it) is the 'Motherboard' or 'Mainboard'.

3rd, The Central Processing Unit or 'CPU'. This is the 'brain' of the system, and is what is referred to when you hear or read something like 'Intel Pentium Dual Core 1.80GHz Processor'. The type and maximum speed of processor that can be put into a computer is wholly dependent upon the Motherboard's socket (or slot) type, as it plugs directly into the motherboard.

4th, The Video Card. Not all pcs have them, as some have video chipsets built right onto the motherboard. Most motherboards don't have onboard video, however, and so to be used they MUST have a video card installed. They come in many different forms, and some systems can have up to 4 cards installed at the same time. That aside, the video card is the circuit board that has the port you plug the monitor into.

5th, The Sound Card. Many (in fact, most) motherboards come with onboard audio chipset, that if the user desires, can be disabled to add a more powerful, and dedicated sound card. This card plugs into the motherboard like the video card does, but into a different type of 'slot'. The sound card is the circuit board that has the ports where you plug in your speakers to hear sound come from your pc.

6th, there can be a large number of different 'card' type hardware additions that can plug into the same slots as devices like the sound card, that can perform a great many different functions. For example there might be a 'video capture card' used to run television (or other t.v. Type signal, like a vcr) through the pc, and allow the user to record or 'capture' the video that comes through it. There are other cards that can add ethernet, add USB ports, wireless connectivity, fiber optic data transfer, or any of a wide variety of functions that the user desires to have built into the pc.

7th, there will be from 1 to (usually not more than) 4 quite small circuit boards, usually with somewhat wide, flat chips on them in different numbers. These are your 'Memory Modules'. They represent the amount of 'memory' in the pc... This term 'memory' gets thrown about quite a bit sometimes, but there is a distinct difference between 'memory' and storage (which we'll cover next). The memory modules are what the system uses to run programs, hold data prior to processing it, and in general to allow the CPU to do it's job, by providing rapid access to the information it needs to execute programs and other tasks.

8th, There will be at least one, and quite commonly more than one, small metal box attached to the mother board by one type of cable or another. These are the Hard Disk Drives, and they represent the storage capacity of your pc. These are the 'long-term' storage locations in your system. When you save a file, this is where it gets saved to. When you need to find that picture of your nephew, you will find it on your hard drive. While many people refer to this as 'memory', that's a bad habit to get into, as it's completely different from system memory, and should always be referred to as 'storage', and the drives themselves as 'disk drives' or 'hard drives'.

9th, there is often a larger drive case inside as well, that usually attaches with the same types of cables as hard drives. This drive is your 'optical drive', and can be anything from a CD-R (only reads, and only from CDs), to a BD-R (Blu-ray disk reader AND burner). Some systems come with multiple such drives, of which usually one is DVD burner and the other is only a CD burner or even just a reader, but it can vary drastically even just from manufacturer to manufacturer...much less user to user.

10th, and for the most part finally, there is a large-ish box usually located at the top of the case, and it has wires that come out from it and go to all the other devices in the system (except for the 'card' type devices, as usually the only one of that type that needs to be connected is the video card, if it's powerful enough to need it)... This is the 'Power Supply', and like it's name says, it supplies power to all they components within the pc.

I hope my overly-verbose answer has helped in some way, and if so, please rate it appropriately. Good luck, and have a great day.
