It is a condition resulting from excessive concentrations of thyroid hormones, as in hyperthyroidism, characterized by bulging eyes and rapid heart rate.

(This set of questions goes to the heart of the corporate culture. Are reporting structures formal or informal? You will not be happy if you prefer an informal, open-door company environment and this company prefers a more rigid structure.)

(It's the interviewer's opinion that is at the heart of the question.)

Active Directory data store, the actual database file, is %SystemRoot%\ntds\NTDS.DIT. The ntds.dit file is the heart of Active Directory including user accounts. Active Directory's database engine is the Extensible Storage Engine ( ESE ) which is based on the Jet database used by Exchange 5.5 and WINS. The ESE has the capability to grow to 16 terabytes which would be large enough for 10 million objects. Back to the real world. Only the Jet database can maniuplate information within the AD datastore.

The Active Directory ESE database, NTDS.DIT, consists of the following tables:

Schema table - the types of objects that can be created in the Active Directory, relationships between them, and the optional and mandatory attributes on each type of object. This table is fairly static and much smaller than the data table.
Link table - contains linked attributes, which contain values referring to other objects in the Active Directory. Take the MemberOf attribute on a user object. That attribute contains values that reference groups to which the user belongs. This is also far smaller than the data table.
Data table  - users, groups, application-specific data, and any other data stored in the Active Directory. The data table can be thought of as having rows where each row represents an instance of an object such as a user, and columns where each column represents an attribute in the schema such as GivenName.

From a different perspective, Active Directory has three types of data

Schema information - definitional details about objects and attributes that one CAN store in the AD. Replicates to all domain controllers.
Static in nature.
Configuration information
configuration data about forest and trees. Replicates to all domain controllers. Static as your forest is.
Domain information
object information for a domain. Replicates to all domain controllers within a domain. The object portion becomes part of Global Catalog. The attribute values (the actual bulk of data) only replicates within the domain.
Although GUIDs are unique, they are large. AD uses distinguished name tag ( DNT ). DNT is a 4-byte DWORD value which is incremented when a new object is created in the store. The DNT represents the object's database row number.
It is an example of a fixed column. Each object's parent relationship is stored as a parent distinguished name tag ( PDNT ). Resolution of parent-child relationships is optimized because the DNT and PDNT are indexed fields in the database.
The size of ntds.dit will often be different sizes across the domain controllers in a domain. Remember that Active Directory is a multi-master independent model where updates are occuring in each of the ADs with the changes being replicated over time to the other domain controllers. The changed data is replicated between domain controllers, not the database, so there is no guarantee that the files are going to be the same size across all domain controllers.
Active Directory routinely performs online database defragmentation, but this is limited to the disposal of
tombstoned objects. The database file cannot be compacted while Active Directory is mounted. An ntds.dit file that has been defragmented offline ( compacted ), can be much smaller than the ntds.dit file on its peers. To defrag ntds.dit offline

The kernel is the heart of the UNIX operating system, it's responsible for
controlling the computer's resources and scheduling user jobs so that each one gets
its fair share of resources.
The work of kernel is divided into mainely five parts -> process management -> memory management -> network interface -> file management -> device controler

It is the chipset. If the CPU is your computer's brain, the chipset is its heart, and of course, one can't function without the other.

Aside from its proven use, ephedra is a main component of many herbal preparations for weight loss, athletic performance, and physical and mental stimulation.
Common side effects resulting from the stimulatory effects of ephedra include headache, irritability, restlessness of muscles, nausea, sleeplessness, increased heart rate, urinary disturbances and vomiting. Higher dosages may result in drastic increases in blood pressure and cardiac rhythm disorders.

Having symptoms of coronary artery diseases , or having significant risk factors for CAD are the main reasons your doctor may recommend a stress test. It may also be given if you complain of unusual fatigue, shortness of breath or irregular heart beat during exercis.
