Text string that acts as a password and is used to authenticate messages sent between a management station and a router containing an SNMP agent. The community string is sent in every packet between the manager and the agent.

Jobs: Using SQL Server Agent you can create and schedule jobs that automate routine administrative tasks. Database administrators create jobs to perform predictable administrative functions either according to a schedule or in response of events and conditions. Jobs can be simple operations containing only a single job step or can be extremely complex operations containing many job steps. SQL Server Agent is responsible for management and execution of all jobs. Agent must be running for jobs to be executed. SQL server 2k supports jobs containing operating system commands. Alerts: database administrators define alerts to provide event and performance condition notification and to execute jobs in response to SQL server events or performance conditions. E.g. when the log is 90% full an alert can be configured to fire a job that executes a job to back up and truncate the transaction log.

 SQL SERVER - is for running the databases
SQL AGENT - is for automation such as Jobs, DB Maintenance, Backups
DTC - Is for linking and connecting to other SQL Servers

SetMaxAge

getMaxAge ():
public int getMaxAge ()
Returns the maximum specified age of the cookie. If none was specified, a negative value is returned, indicating the default behavior described with setMaxAge.

It is an agent that, when administered prenatally (to the mother), induces permanent structural malformations or defects in the offspring.

both cause harm to human health..but
bacteria is single-celled or noncellular spherical or spiral or rod-shaped organisms lacking chlorophyll that reproduce by fission; important as pathogens and for biochemical properties; taxonomy is difficult; often considered to be plants
virus is an ultramicroscopic (20 to 300 nm in diameter), metabolically inert, infectious agent that replicates only within the cells of living hosts, mainly bacteria, plants, and animals: composed of an RNA or DNA core, a protein coat, and, in more complex types, a surrounding envelope.

viruses are more dangerous than bacteria...

catalyst is an agent that is added to fasten the chemical reaction.
