2. C. The switch with the lowest switch ID is elected as the root switch. A and B are incorrect because the decision is based on the switch ID, which includes the switch s priority and MAC address. D is incorrect because it is the lowest, not the highest switch ID. 3. D. The switch port that is chosen to forward traffic for a segment is called a designated port. A is incorrect because the root port is the port that the switch uses to reach the root. B, the alternate port, is used in RSTP and is a secondary root port, and C, the backup port, is used in RSTP and is a secondary designated port. 4. A and D. In a listening state, the port processes and forwards BPDUs. A port stays in the listening state for 15 seconds. B occurs in the learning state. C is the time period for the blocking state.

always be a little less than 1. However, even though the common-base amplifier has superior temperature stability and linearity, and can easily operate at very high frequencies, it is not nearly as common as the other two configurations, the common-emitter and the common-collector amplifier. This is due partly to the common-base amplifier s low input impedance (50 to 75 ohms), but these amplifiers can occasionally be found at the 50-ohm antenna input of a receiver, or sometimes as Class C high-frequency amplifiers. The JFET version of the BJT common-base amplifier, a common-gate amplifier, can be seen in the IF section of receivers; one such circuit is shown in Fig. 3.2. C2, C3, R2, and the RFC are for decoupling; C4 and C6 are for RF coupling; C5 can be tweaked to obtain a flatter frequency response throughout its passband; T1 is for matching of the low input impedance, as required. The most popular amplifier circuit arrangement in all of electronics is the common-emitter type of Fig. 3.3. It has the greatest current and voltage gain

4. Click OK to close the query panel. 5. From the Object Properties dialog, click Display in the bottom right and then Refresh from the List Of Values dialog. You will be prompted to choose a country before you can see the newly filtered set of customer IDs. 6. You may either click Values to choose from a list of countries or enter France and click OK. Notice how much smaller the list of Customer IDs is now compared to the list in Step 6 under the earlier heading Adding More Information.

involves forensic identification to identify missing persons or the deceased, a technique used to identify many of the victims of the September 11, 2001 terrorist attacks. DNA is attractive to use for these applications because of its accuracy of typing, relative ease of use, and high levels of polymorphism. To be clear, the parts of the DNA that are used for law enforcement and forensic purposes are located in those parts of the chromosomes without known functions or, if part of a gene, not in the part that produces a detectable effect. The use of this so-called junk DNA is, in part, done to protect individual privacy. In the United States, this acceptance of DNA has led to the establishment of databases of DNA samples. For example, The DNA Identification Act of 1994 (Public Law 103-322) provided the Federal Bureau of Investigation (FBI) with the authority to establish a national DNA index for law enforcement purposes. Based on this statute, the FBI operates the Combined DNA Index System (CODIS) that enables federal, state, and local crime labs to exchange and compare DNA profiles electronically. CODIS provides investigators with leads in crimes where a DNA sample is recovered from the crime scene. CODIS is implemented as a distributed database with three tiers local, state, and federal. The National DNA Index System (NDIS), the highest level in the CODIS hierarchy, enables the laboratories participating in the CODIS program to exchange and compare DNA profiles on a national level. DNA profiles originate at the local level (for example, when the local police obtain a DNA sample from a crime scene or, when upon conviction, a criminal is required by law to give up a DNA sample), and then go on to the state and national levels. NDIS relies on two databases to operate the Forensic Index and the Offender Index. The Forensic Index contains DNA profiles from crime scene evidence. The Offender Index contains DNA profiles of individuals convicted of sex offenses (and other violent crimes), with many states now expanding legislation to include other felonies. As of August 2002, the Forensic Index contained 39,096 profiles and the Offender Index contained 1,119,127 profiles. All but six states participate in this system. In Virginia and in many other states, on conviction of a felony, an individual must provide a DNA sample to the state. As the FBI explains it, Matches made among profiles in the Forensic Index can link crime scenes together possibly identifying serial offenders. Based on a match, police in multiple jurisdictions can coordinate their respective investigations and share the leads they developed independently. Any match(es) that are made between the Forensic and Offender Indexes provide the authorities with the identity of the perpetrator(s). The CODIS system has digital representations for the DNA profiles (templates) and performs automated matching. For example, when DNA is found at a crime scene, it can be searched against the DNA database for a possible match. Matches are regularly made because a large number of criminals are recidivists. As a National Institute of Justice working group concluded in 2000, The scientific foundations of DNA are solid.

where w is the work required to move the charge w across the potential difference. To nd the energy acquired by a charge, we examine the units of voltage, which are given as joules per coulomb which is energy per charge. Therefore to nd the energy that a charge gains or loses when passing through a potential difference, we multiply the charge carried by the voltage E = qV (1.10)
