Ron Keliipio: A graphics card is the component in your computer that handles generating the signals that are sent to the monitor or "graphics". It is responsible for generating all the text and pictures that are displayed on your screen. It is called a "card" because most PCs will have a physical card that is inserted in a PCI slot on the motherboard. Some motherboards have built-in graphics cards with is something of a misnomer since it is built in as part of the motherboard and no longer a separate "card". 2D, or two dimensional graphics are the kind of graphics displayed when you use a web browser, check email or work on a spreadsheet. For 2D graphics the major factors are resolution and refresh rate. Resolution determines how many little dots are used to draw the image on the screen. For example, 640x480 means that the whole screen is drawn using 307,200 little dots in 640 columns and 480 rows. The more dots that are used, the finer the detail. Thus, higher resolution! s provide for great detail and image quality. Another factor is color depth. You may see it expressed as a third parameter such as 640x480x256. This means 640 columns x 480 rows x 256 colors. Color depth is usually a number that is 2 raised to the power of a multiple of 8 up to 32. i.e. 2^8, 2^16, 2^24 or 2^32... or 256, 65,536, 16M or 4G colors. Obviously, the more colors the great the detail again. Finally refresh refers to how many times a second the image on the screen is redrawn. 60Hz means that the image on the screen is drawn 60 times every second. This becomes important in fast moving video games where the action needs to look really. Also, for CRT type monitors refresh rates of 60Hz and less tend to have a noticeable flicker even on stationary images. This flicker can lead to headaches for many people. Higher refresh rates are better. Of course, having a graphics card with the higher possible resolution and refresh rate doesn't do much good if your monitor doesn't ! also support this capabilities. the GIG part means that it ren! ders graphics faster and gets you more framerates in games(less lag). You can run more graphically advance applications as well.Central Processing Unit (CPU), or sometimes simply processor, is the component in a digital computer capable of executing a program.(Knott 1974) It interprets computer program instructions and processes data. CPUs provide the fundamental digital computer trait of programmability, and are one of the necessary components found in computers of any era, along with primary storage and input/output facilities. A CPU that is manufactured as a single integrated circuit is usually known as a microprocessor. Beginning in the mid-1970s, microprocessors of ever-increasing complexity and power gradually supplanted other designs, and today the term "CPU" is usually applied to some type of microprocessor.It interprets the information from the hardware, makes the appropriate services available to other parts of the system, presents user interfaces and interprets t! he user input. It then runs every piece of code and processes all the data generated the bigger the CPU the faster the Data is processed...Show more

Marcellus Yoshimori: At first you know about all kind of parts. And learn about the using. You can learning those parts manual and diagram.
Marna Liddie: Use the internet for more then just asking questions
Donald Caravalho: books ? no, things evolve too fast. use forums
Hans Sachetti: Ge! t C+ exam.. Other than learning you will get a certification
