Question 2. Computer Purchase
Let us assume that you are purchasing a new computer for a specific usage. You need to choose a computer from various available configurations.
Listed below are four different usage cases of a computer (a-d). For each usage case, identify components of the computer configuration that are most important to consider. Explain your answers.
Components to be considered include (but are not limited to):
· Monitor size/resolution
· Graphics card/video card
· Storage devices (for example, DVD-ROM)
· Memory (RAM, cache, and hard disk)
· Disk controller interfaces (ATA, EIDE)
For example, if a computer were to be used for viewing movies, a DVD-ROM drive is needed since movies are available as CDs and now increasingly as DVDs. A large monitor (about 19”) that supports high resolutions and a video card will also be necessary to enjoy the movie.
