Solution
1.under the domain name service (DNS) protocol, in the address someone@name1. name2.
name3. name4, the host name is_____
b. name1
2._____ techniques in an object- based DO/S give the system the ability to perform concurrent
reads and writes, as long as the results of these actions don\'t jeopardize the contents of the
database.
d. concurrency control
=> The results of all concurrent transactions are the same as if the transactions had been
executed one at a time, in some manner, thus providing serial serialexecution view on database
3. Subroutines that work with the operating system to supervise the transmission of data
between main memory and a peripheral unit are called____.
c. device drivers
=> If the computer uses device that are not supplied with operating system, they should be
obtained from a reliable source.
4. the major difference between a Nos and DO/S involves__how each views and manages the
local and global resources.___.
b. the management of local and global resources.
5. which of the following is a popular distribution of Linux?
b. Ubuntu
=> Ubuntu project has a focus on providing a solid desktop (and server) experience, and it isn’t
afraid to build its own custom technology to do it.
6. A__blended threat__ combines into one program that characteristics of other attacks
including a virus, a Trojen, a worm, key loggers spyware. This single program sues a variety of
tools to attack systems and spread to others.

d. basic cost, Communications cost, reliability, and users environment
=> basic cost : expense to link various sites in system
Communications cost : time required to send message from one site to another
reliability : sutes can communicate if there is a failure
users environment : parameters the network must meet for a successful business investment
