(A)-Graphics Card
A graphics card is the hardware for a computer that produces the images that we see on the computer monitor. The Cards main job is to decide on how the pixels on the screen will be used to create the image then information that is creates is sent to the monitor through a cable. The graphics card has four main parts that it uses to complete the tasks. These are the motherboard where the power and data is connected through a connector, the processor this tells it how to use each pixel on the screen, memory which holds the picture and the monitor where the image will be displayed. The graphics card is normally built straight into the computers motherboard. The better the quality of the graphics card and the higher the capacity

Internal memory normally means memory chips that is inside the computer with technology changing these used to be disks or tapes that was used for internal memory. Ram memory is found on the computers motherboard, so every time the computer opens a program it will be loaded and opened into ram which will make the process faster, the more ram that the computer has will meant he faster it will run and be able to complete tasks. The CPU in the computer uses cache memory as it will speed up the memory of the computer. Cache memory is mainly used to open the most used computer programs as it will decide these and help them to load …show more content…

    This data is transferred to the printer that controls “a nozzle that extrudes heated thermoplastic” to build each layer of on top of each other. Since the object is built on a base, the finished product can be easily removed. The third method is called Selective Laser Sintering (SLS). [6] This method works similarly to SLA, but it uses powered materials instead of liquid resin. All of the current competing methods to CLIP are based on a layer-by-layer approach, which is not only timing consuming, but the finished products are fragile, and have rough surfaces.…

    According to the ece “Computer engineer embed computers in other machines and systems, build networks to transfer data, and develop ways to make computers, faster smaller and more capable.” Computer engineering is all of these combined because it focuses on one thing, that is computers. Computer engineering is when you are putting all of the components of the computer together and programming the computer and wiring the computer. Electrical engineering is when they design the electrical components of the computer and making it. Computer engineering also includes putting all of the programs in the computer and programming it. Computer engineers us the programs that they would get from computer science programming to improve on low fast the computer can get and the protective program to fend of things like virus.…

    The process function is done by the CPU, central processing unit of the computer which acts as the brain, and this is located on the motherboard or main circuit board that contains the electronic components used to run the computer. The CPU controls and handles the hundreds of commands or input that is fed into the computer by various means. The speed in which it performs this is determined by the size of the CPU and memory it has enabling it to decode all the instructions that are being entered. The motherboard also houses slots for expansion cards giving the computer additional space for more circuit boards. By using expansion cards it gives the computer more versatility allowing it to emit sound through speakers, and even allowing a connection for optional video…

    IBM 701 still used a vacuum tube circuitry but used magnetic memory storage and could hold a maximum of 2048 words. Although it was relatively cheaper compare to the ENAIC, it still cost $4000 at the time and $35000 adjusted for inflation. Transistor was the first major breakthrough for electronic computers as it was much smaller and consumes a lot less power compare to the vacuum tube. University of Manchester created the first transistorize computer in 1953, and by 1955, the computer had only 200 transistors and consumed 150 watts. Then the discovery of the semiconductor silicone took the transistor to the next level; thousands or millions of transistor can be pack on to a tiny chip, and as a result, the computer processing power increase exponentially by the year.…

    3D printers work automatically by reading digital files from the computer called CAD (Computer Aided Design) files. These files are created using a 3D modeling program in the computer. Like every printer it has to use some form of ink. However, a 3D printer works slightly differently as it uses various materials such as polymers, plastic and maybe even metals as “ink” to print the object. Now u may be thinking what are 3D printers used for, and more importantly how do they contribute to better healthcare?…
