broadcast A transmission sent simultaneously to more than one recipient. In communication and on networks, a broadcast message is one distributed to all stations or computers on the network. broadcast storm An event that occurs when there are so many broadcast messages on the network that they approach or surpass the capacity of the network bandwidth. This can happen when one computer on the network transmits a flood of frames, saturating the network with traffic so it can no longer carry messages from any other computer. Such a broadcast storm can shut down a network. buffer A reserved portion of RAM in which data is held temporarily, pending an opportunity to complete its transfer to or from a storage device or another location in memory. built-in group One type of group account used by Windows XP Professional. Builtin groups, as the name implies, are included with the operating system and have been granted useful collections of rights and built-in abilities. In most cases, a built-in group provides all the capabilities needed by a particular user. For example, if a user account belongs to the built-in Administrators group, logging on with that account gives the user administrative capabilities. See also user account. bus Parallel wires or cabling that connect components in a computer. byte A unit of information consisting of 8 bits. In computer processing or storage, a byte is often equivalent to a single character, such as a letter, numeral, or punctuation mark. Because a byte represents only a small amount of information, amounts of computer memory are usually given in kilobytes (1024 bytes or 2 raised to the 10th power), megabytes (1,048,576 bytes or 2 raised to the 20th power), gigabytes (1024 megabytes), terabytes (1024 gigabytes), petabytes (1024 terabytes), or exabytes (1024 petabytes).

When you assign permissions, grant users the minimum permissions that they need to get their job done. When you move files or folders within an NTFS volume, permissions that have been directly assigned to the file or folder carry over to the new location. In all other cases, existing permissions are lost and the object will inherit permissions from the new parent. Remember the limitations of Simple File Sharing when you explore a situation on the exam. Simple File Sharing is really an all-or-none proposition; the object is shared with everyone on the network or not shared at all.

Note that the IDENTITY property can be specified only when creating a new column. An existing column cannot be modified to use the IDENTITY property. To change an existing column, the existing column must be dropped and the identity column added in its place. The identity column can be used only on data types that store whole numbers, which include both the integer data types and the decimal data type with a scale set to 0. Another important point to note with identity columns is that they are not guaranteed to generate complete sequences. If an insert fails, it still uses the identity value, creating a hole in the sequence. Consider this example:
