Graphic is a series of commands that describe a line’s direction, thickness, and color. The file sizes for these formats tend to be small because every pixel does not have to be accounted for. The complexity of the image, such as the number of items in the picture, determines the file size. A raster graphic such as a GIF must be encoded multiple times for different sizes and proportions. Einstein describes the telegraph Vector graphics can be resized mathematically, and “You see, wire telegraph.

Street for the street address, cityState for the city and state, telephone for the 10-digit telephone number, and eMail for the e-mail address. These names are called identifiers. In the next two chapters, we describe how these fields become associated with memory locations and how the input data becomes the contents of these places. For the moment, you can defer these details until later. Now that we have the names and associated data, we can insert the data into the list. Do we need to further.

Design is a problem-solving methodology based on breaking a problem into successively smaller tasks until each task is a concrete step that can be coded in a programming language. This structured design view sees each module as a step in the overall process. Thus, top-down design decomposes the problem into algorithmic steps. Object-oriented design is based on looking for the objects in the problem rather than tasks to be solved. Thus, object-oriented design decomposes the problem according to.

Surfing, and e-mail are probably familiar terms to you. Some of you can define these and many more computer-related terms explicitly, whereas others may have only a vague, intuitive understanding of them. This chapter gets everyone on relatively equal footing by establishing common terminology and forming the platform from which we will dive into our exploration of computing. 3 Chapter 1 4 The Big Picture Goals After studying this chapter, you should be able to: ■ ■ ■ ■ ■ ■ describe the.

Layers of a computer system. describe the concept of abstraction and its relationship to computing. describe the history of computer hardware and software. describe the changing role of the computer user. distinguish between systems programmers and applications programmers. distinguish between computing as a tool and computing as a discipline. 1.1 Computing system Computer hardware, software, and data, which interact to solve problems Computer hardware The physical elements of a computing system.
