Document Summary
A network consists of two or more computers that are connected by physical cables or satellite and radio communication. Cd-r opens (reads) files and the cd-w transfers (burns/writes) files from your hard drive onto the cd. Digital video disks (dvds), can store more information than cds. Universal serial bus (usb) flash drives have huge storage capacities. Secure digital (sd) cards are also flash drives that are often found in cell phones, pdas, and digital cameras. The workspace for a spreadsheet file is called a workbook. Each workbook includes one or more worksheets that are large grids of rows and columns. Each column (vertical) is represented by one or more letters, and each row (horizontal) is represented by a number. The intersection between a row and a column is called a cell. Each cell is identified uniquely by its location within the grid, and this unique combination is called the cell"s address.
