AND =AND(logical1, [logical2],...) OR =OR(logical1, [logical2],...) NOT =NOT(logical) IF =IF(logical_test, [value_if_true], [value_if_false])

Microsoft ® Excel ® Logical Functions Syntax: =AND(logical1, [logical2],...) Arguments: logical1 Required  The first condition that you want to test that can evaluate to either TRUE or FALSE. logical2,... Optional  Additional conditions that you want to test that can evaluate to either TRUE or FALSE, up to a maximum of 255 conditions.

Microsoft ® Excel ® Logical Functions Description: Returns FALSE if one or more arguments is FALSE Otherwise, all arguments must evaluate TRUE Remarks: Arguments must evaluate to logical values Arguments must be arrays or references that contain logical values Text and empty cells are ignored in arrays or references Errors: #VALUE – If no logical values exist in a specified range

Arguments: logical1 Required  The first condition that you want to test that can evaluate to either TRUE or FALSE. logical2,... Optional  Additional conditions that you want to test that can evaluate to either TRUE or FALSE, up to a maximum of 255 conditions.

Microsoft ® Excel ® Logical Functions Description: Returns TRUE if one or more arguments is TRUE Otherwise, all arguments must evaluate FALSE Remarks: Arguments must evaluate to logical values Arguments must be arrays or references that contain logical values Text and empty cells are ignored in arrays or references Errors: #VALUE – If no logical values exist in a specified range

Microsoft ® Excel ® Logical Functions Syntax: =NOT(logical) Arguments: logical Required  A value or expression that can be evaluated to TRUE or FALSE.

Syntax: =IF(logical_test, [value_if_true], [value_if_false]) Arguments: logical_test Required  Any value or expression that can be evaluated to TRUE or FALSE. value_if_true Optional The value that you want to be returned if the logical_test argument evaluates to TRUE. If logical_test evaluates to TRUE and the value_if_true argument is omitted (that is, there is only a comma following the logical_test argument), the IF function returns 0 (zero). To display the word TRUE, use the logical value TRUE for the value_if_true argument.

Microsoft ® Excel ® Logical Functions Syntax: =IF(logical_test, [value_if_true], [value_if_false]) Arguments: value_if_false Optional  The value that you want to be returned if the logical_test argument evaluates to FALSE.  If logical_test evaluates to FALSE and the value_if_false argument is omitted, (that is, there is no comma following the value_if_true argument), the IF function returns the logical value FALSE.  If logical_test evaluates to FALSE and the value of the value_if_false argument is omitted (that is, in the IF function, there is a comma following the value_if_true argument), the IF function returns the value 0 (zero).

Microsoft ® Excel ® Logical Functions Description: The IF function returns one value if a condition you specify evaluates to TRUE, and another value if that condition evaluates to FALSE. Remarks: Up to 7 IF functions can be nested as value_if_true and value_if_false arguments to construct more elaborate tests. (2003) Up to 64 IF functions can be nested as value_if_true and value_if_false arguments to construct more elaborate tests. (2007) If any of the arguments to IF are arrays, every element of the array is evaluated when the IF statement is carried out. Errors: None

 Question (MIS, Ch 4) Hardware, in computer terms, refers to the physical components of the computer. Answer  True  False

 Question (MIS, Ch 4) Businesses that handle large volumes of retail transactions often store this data in a corporate data center on mainframe computers, which many I.T. professionals fondly refer to as “big iron” in their lingo.  Answer  True  False

 Question (MIS, Ch 4) Because _____ reduces the amount of paper in organizations, some of its most enthusiastic adopters are companies in paper-intensive fields such as law, retail, insurance, and banking. Answer  processing  OMR  imaging  printing

 Question (MIS, Ch 5) To accelerate their work, application developers can use one of several _____ programming languages, such as Microsoft Visual Basic, Borland Delphi, Micro Focus COBOL, ASNA Visual RPG, and Visual C++.  Answer  visual

 Question (MIS, Ch 4) What factors make one computer more powerful than another?  Answer The two major factors to consider are processing speed and memory capacity. A computer’s speed is determined, among other factors, by the CPU clock rate (measured in MHz or GHz), and the amount of information the CPU can process per cycle (determined by the size of the data word and the capacity of internal data communication, which is often referred to as bus width). However, the architecture of the various computer components also plays a significant role in determining processing speed. To mention one, consider the discussion of multi-core CPUs. When two computers are built with the same components except the number of cores, the computer with the greater number of cores is faster.

 Question (MIS, Ch 5) Which of the following refers to sophisticated and interactive multimedia applications that run on more powerful personal computers?  Answer  polymedia  hypermedia  virtual reality  temporal reality

 Question (MIS, Ch 5) The most sophisticated virtual reality (VR) devices provide which of the following elements? (select one or more answers) Answer  immersion  interaction  intersection  immobility

 MIS, Ch 4) The data access mode for tape storage devices is:  (A)direct  (B) random  (C) sequential  (D) none of the above

 MIS, Ch 5) Which of the following is considered to be a type of systems software?  (A) compilers  (B) communications  (C) interpreters (D) utilities  (E) all of the above

 (Excel) An interstate trucking plaza is offering a discount on all diesel pumped based on the total quantity purchased. Which of the formulas below calculates the correct total price to charge the trucker for the diesel they have pumped based on the following conditions: A- no discount (zero dollars off the total amount due) if a trucker purchases less than 50 gallons of diesel B-a 5% discount on all diesel purchased if the person dispenses at least 50 gallons into their tank

 Assume that cell A1 shows the total quantity (in gallons) of fuel purchased and cell B1 is the price per gallon. Provide a formula that will correctly calculate the total amount that a person should pay, after the discount (if any) has been applied. =IF(A1<50, A1*B1, A1*B1*95%) and then apply some algebra to get: =A1*B1*IF(A1<50, 1,.95) note the different format (no percent)

 (MIS, Ch 5) Since Microsoft does not make the source code for Internet Explorer available for end users to review and update, the product is considered proprietary.  True  False
