What are the advantages and disadvantages of the Linnaean naming system?
I can tell you the many advantages. First it is in a common language that scientists use with each other, Latin, also this way scientist have one name for one organism, not many different names for one organism or the same name for many organisms. Each organism only has one scientific name from C. Linnaeus's system, and each name is only given to one organism. This way there will not be mistakes in translation about which organism is being spoken of. Linnaeus's naming system consists of two parts, the genus and the species. So not only does the identify the organism but it also identifies the group of close relatives it belongs in.

What is an almost complete binary tree?
An almost complete binary tree is a tree in which each node that has a right child also has a left child. Having a left child does not require a node to have a right child. Stated alternately, an almost complete binary tree is a tree where for a right child, there is always a left child, but for a left child there may not be a right child.The number of nodes in a binary tree can be found using this formula: n = 2^h Where n is the amount of nodes in the tree, and h is the height of the tree.

What is difference between distriduted database and centrlized database system?
This relates to deployment of application. Centralized DB : Where the data for application shall be stored in one location and the users can access the database using the application provided from anywhere using the network (LAN/WAN/Internet etc) Distributed DB: The application & the database shall be deployed where ever required and there will be some mechanism to synchronize the data between these databases.
In more of layman' s words: In centralized DB the database is stored in a central server and all user have access to that DB, and any changes made by any user in DB is reflected in central DB, thus visible to all the users using it.
In distributed DB the DB is stored in multiple locations(say different computers on a lan or on a remote location comp). It is more of a kind of more than one copy of a single DB and changes in one copy doesn't reflects immediately , it is rather responsibility of DBA to ensure security and more importantly ensure the Integrity of Data in several locations(all copies).
Distrubuted DB is fast to work with but incurs a lot of head-ache for DBA to ensure Security and data Integrity, also expensive to maintain.
Whereas centralized DB is more reliable and reflects changes immediately thus ensuring data integrity and bit of less overhead in security. But Load on a centralized system is too high if users are more, so might slow down the performance and would incur greater response time.

What is the sanhedrin view of celebacy?
Celebacy is forbidden by Jewish law - and a celebate was disqualified from serving on the Sanhedrin. The creation of man ends as recorded in Genesis 2:24 with the words: Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh. The first commandment in the Torah is to be fruitful and multiply; to have children.
Centralized control of data by the DBA avoids unnecessary duplication of data and effectively reduces the total amount of data storage required. It also eliminates the extra processing necessary to trace the required data in a large storage of data. Another advantage of avoiding duplication is the elimination of the inconsistencies that tend to be present in redundant data files. Any redundancies that exist in the DBMS are controlled and the system ensures that these multiple copies are consistent.
