It would need to be reasonably powerful to develop and test games on and dual graphics adapters would probably be needed. You would definitely consider a desktop computer for this job though, not a laptop
No. Some computer speakers require AC adapters, while others can run simply on battery power or USB.
All computer have a graphics card these days. Your computer needs a graphics card to allow the picture you see on the screen to be manipulated without being slow or jerky/jumpy.
Because allows you to view the graphics from a computer. If there is insufficient video memory, the system 'borrows' available space from the RAM, which in turn robs you of processing speed and slows the computer down. If you require graphics intensive programs to run, such as 3D games, you need a graphics card with it's own memory chips.
The technical specifications of computer graphics include the resolution (number of pixels), refresh rate (number of frames per second), color depth (number of colors), graphics memory (VRAM), and graphic processing unit (GPU) performance. These specifications determine the quality and performance of visual output on a display.
Most games require you to have a graphics card. These are fitted to the motherboard and provide a video output. Most graphics cards will also require you to install drivers.
An AC Adapters are a type of external power supply which is often enclosed in a case. AC Adapters are used within electrical devices that require power but do not contain internal components to derive the required voltage and power from the mains.
Completely stock? No. A better graphics card will be required; which unfortunately will require a new power supply unit.
A video adapter is a circuit board for attaching a monitor to a computer. Some computers have built-in graphics cards, and others require a 3rd-party card. Video cards not only make graphics possible, but also have a processor known as a graphics processing unit (GPU) which can do a number of graphics tasks without requiring CPU intervention.
25 Watts I depends entirely on the card you use in the slot. For example, in graphics cards can require 500 watts at times, whilst a sound card may require much less.
A computer without a graphics card will have no video output. Therefore you'd only be able to play games which do not require any visuals. (I'm counting CPU's with graphics cores and built in chips as a graphics card.) a game of battleship that has no graphics and only text.... assuming you have a way to input digits and a readout or Pong if you just have a oscilloscope.
some jobs or careers require computer assistance!!! computer knowledge is very important for someone that is going into the computer feild!!! this is how computer knowledge can be applied in life!
The past tense of "require" is "required."
