Draw an er diagram for the following situation: a lab has several chemists who work on one or more projects. chemists also may use certain kinds of equipments on each project. o attributes of chemist include employeeid (identifier), name, and phoneno. o attributes of project include projectid (identifier), and startdate. o attributes of equipment include serialno (identifier) and cost. o the organization wishes to record assigndate, the date when a given equipment item was assigned to a particular chemist working on a specified project. o the organization also wishes to record the association between the project and chemist. a chemist must be assigned to at least one project. any number of chemists may work in a project. o a given equipment item need not be assigned, and a given project need not be assigned any equipment item.

Data is processed, stored, and transmitted as a series of 1s and 0s. each 1 or 0 is called a(n) . a series of eight 0s and 1s, called a(n) , represents one character—a letter, number, or punctuation mark. data becomes when it is presented in a format that people can understand and use. digital signals are represented by two different , such as +5 volts and +.2 volts. digital data can also take the form of light and dark spots etched onto the surface of a cd or the positive and negative orientation of particles on the surface of a hard disk. data consists of numbers that might be used in arithmetic operations. it can be represented digitally using the number system. data is composed of letters, symbols, and numerals that are not used in arithmetic operations. computers represent this type of data using , ebcdic, unicode, or utf-8. data is quantified using terms such as or kibibyte (1024 bytes), and prefixes such as or mebi (1,048,576), and giga or (1,073,741,824). to reduce file size and transmission times, digital data can be compressed. compression provides the means to compress data and reconstitute it into its original state. compression throws away some of the original data during the compression process. compressed files usually have at the end of the file name and are represented with special icons. these files have to be or unzipped before you can view the data they contain.

What are the most likely causes of conflict at the meeting? check all that apply.

It is vital to research each of the services you plan to disable before implementing any change, especially on critical machines such as the: a. servers in the test environment. b. domain controller and other infrastructure servers. c. desktops that have previously been attacked. d. desktops used by upper-level management.
