What are the types of processor?
As of mid 2016, you are probably looking for an Intel i7 series.
Some sites say that the i7 6700k is the very best for gaming. It has four cores and eight threads. It has an 8MB cache and supports DDR4 and DDR3L.
Other sites say that the i7 5960X is the best. It is definitely more expensive, but it depends on who you talk to as to whether they will tell you it is definitely better, or whether the performance is close to identical, and you should get the cheaper one. :)

What type of Fuse is used in computer power supply?
If you mean the fuse in the plug that connects to the mains... no more than a 5 amp fuse.
What are the advantages of USB ports relative to parallel and serial ports?
The serial and parallel ports are slow,have limited expandability and don't carry their own charge of electricity.these ports work fine for connecting Printers, Mice and keyboards to PC but all these device will perform better if connected to a USB port
How do you print only black when your color print cartridges are empty?
Of course YES. All the color printers are enabled to do that. There are two ways.
1. Even when your color cartridge is full with ink (color) you can print B/W (black). This is done my selecting File>Print>Properties>Advanced>TIFF(monochrome) in windows. Other OS's I dont know. Same way when you are out of color also.
2. When your color cartridges are out of color, the advanced printers can automatically print BLACK. However, this can be done only in few advanced printers like SAMSUNG, HP LASERJET and few others.
I would recommend the first option. Because it gives the right amount of GRAY tinge to the print and it is safe and easy and also works on all occasions.
Better tell all the people that sell printers about this YES answer, most will tell you that NO they will not print in b/w when the color is gone. I hope I'm wrong about this
Is a keybaord input or output?
The keyboard is an input device because you use it to type, which is a form of input. Another form of input is the mouse, which sends clicks and mouse movement to let you click on links and move the mouse around.
They could be the RAM modules or Random Access Memory modules. They are solid state memory devices which are volatile in nature. This means that their memory gets deleted or reset when the system is turned off or shut down.
Other boards are in the expansion slots. Mostly PCI. Where you can add video capture, extra USB's or Extra sound cards etc.
There are also slots for improving the graphics, by plugging in a graphics card, with it's own memeory and processor, it improves on the default graphics of the motherboard and allows fast graphics for games and video processing.

A bar code is used to keep up with merchandise that is being sold, returned or what you have in inventory. A barcode is an optical machine-readable representation of data relating to the object to which it is attached.
What is the purpose of bench marking a CPU?
The purpose of benchmarking a CPU is to assess its performance.
This is essential when designing a CPU because designers need to be able to make tradeoffs and measurements in their decisions regarding the chips' microarchitecture for maximum performance.
This is also essential when designing software to determine which (if any) available CPUs will have the needed performance for the application being designed, especially when designing for an embedded system where the user has no access to the CPU or other hardware for upgrades.
Is it necessary to have a graphics card to play minecraft?

And I'm sure there's other stuff, but I don't remember everything.
The two types of primary memory are?
Volatile memory refers to RAM that needs to be constantly refreshed to be retained. Static memory is permanent storage that is retained even after the computer is turned off.
What type of storage drive contains spinning platters?
A hard disk drive consists of one or more thin disks that spin at high speed (1200 to 15000 rpm) while magnetic heads read data from them, hovering extremely close to them without making contact.
Name one way BIOS and drivers are them same Name one way they are different?
1. Both relate to hardware, but device drivers are stored in hard drive
Give commonly use tools and equipment in hardware servicing?
As a former computer tech, I can say that screwdrivers are the most used tool. You can buy a handy kit that has the most common tools at electronics and computer repair shops for 10 to 15 dollars. It will have screwdrivers and nut drivers along with an IC puller, assorted tweezers and other "grabbing" tools. You should also have a grounding strap that attaches to your wrist.

What is the significance of processor speed on computing?
The system mother board has a clock speed; two to three-times this is usually the memory speed, and four-times this is most always the Front Side Bus (FSB) speed. Think of an 18-speed bicycle. The lower the gear ratio the steeper the hill you can pedle up. For the CPU it is the higher the CPU Core speed the more computer instructions you can process. The point is... how many instructions/how steep is the hill you have to deal with; will determine how important getting that next CPU core multiple of the base clock speed. CPU core speed multiples is more like the bike going down-hill, sometimes you just can't peddle fast enough to keep your feet on the peddles. Most of us don't really have the data cruching need for that extra $100 or $300 for those fractions of a second we will save going from a core multiple of 9 to 10 or 11 times the board frequency; which is also the ratio of speed boost, 10:11 is not much of an improvement. Most important is getting the computer with the features you need. When it costs a $100 more for the next CPU core multiple and your only speending $100 on a video board or only getting 512 MB of memory... get the $200 video board or get the 2 GB of the fastest memory... for your system mother board!
