Implement a USB hub and add a USB 2.0 expansion card - You can add USB ports to a computer by implementing a USB hub and by installing an add- on USB expansion card.
Define Terms Computer: A programmable electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations. Mainframes, desktop and laptop computers, tablets, and smartphones are some of the different types of computers. Bit: A single digit of binary notation, represented either by 0 or by 1 binary numbers : A system of numerical notation to the base 2, in which each place of a number, expressed as 0 or 1, corresponds to a power of 2: Byte: The storage space in a memory or other storage device that is allocated to such a group of bits random-access memory(RAM): Random-access memory; computer memory available to the user for creating, loading, or running programs and for the temporary storage and manipulation of data, in which time of access to each item is independent of the storage sequence. As a storage medium, RAM is volatile, so its contents are lost when the power fails or is turned off. character set : the numbers, letters, punctuation marks, and special symbols that can be used by a particular device, as a printer, or in a coding method, as ASCII.
CMIS102 Homework 2 Student Name: Josue A. Contreras Class/Section: CMIS102 Section 6392 Professor: Larry Voss Due Date: 01 FEB 2015 Program Description: This program will be utilized to determine the total cost of building a state of the art gaming computer by utilizing a basic model computer and upgrading three key hardware components. Analysis: Input: The program input consists of the following: base price (BasePrice) graphics card choice (GraphicsCard_Choice) Power supply choice (PowerSupply_Choice) hard drive choice (HardDrive_Choice). Once the user has made the required choices, the program will determine the appropriate cost for that option: GraphicsCard_Cost PowerSupply_Cost HardDrive_Cost Output: The program’s required output consist of the following:
