Finally, IP specifies four additional fields in the IP header of a packet that require further explanation: Type of Service (TOS), Time to Live (TTL), an Options field for additional customization, and a Header Checksum field Figure 5-1 provides a breakdown of an IP packet, along with a basic description of each of the fields

The TOS field in an IP packet tells network devices along the path what priority, or precedence, the packet has, and how much delay, throughput, and reliability it requires The TOS field is generally used by protocols at other layers (such as ATM) to define quality of service (QOS) parameters and modify queues along the path of a connection The TTL field in an IP packet is used to discard packets that have been en route for too long The TTL is measured in seconds and is an 8-bit field, making the maximum time a packet could be in transit 255 seconds In reality, a packet will never reach this limit because each device (mainly routers) operating at layer 3 or above along the path is required to decrement the TTL by at least one, even if the device has the packet for less than one second When the TTL field reaches zero, the packet is discarded This field exists so that, in case a packet is caught in a routing loop, it will not circle the network endlessly The Options field is of variable length and is rarely used (it would be the last field in an IP header, but is not shown in Figure 5-1) A few standard options have been defined, which consist mainly of fields for source routing (where the source device determines the route for a packet) and security descriptions for the DOD (secret, top secret, and so on) The Header Checksum field is a simple computation that can adequately detect bit errors in the IP header If bit errors are detected in the header, the packet will be discarded

Resolution in digital photography refers to the number of individual pixels (discrete picture elements) that are used to define the detail in the image Think of pixels as tiny, solid-color square tiles in a very large mosaic tabletop picture Image size is defined by pixel dimensions, as in 640 480, which refers to the number of horizontal (640) and vertical (480) pixels in the matrix that makes up the picture The higher the resolution, the clearer and more detailed the picture appears
