keyboard is also similar in appearance and function as the typewriter keyboard. The computer keyboard, however, features special keys called function keys to allow  users  to  operate  the  computer’s  functions  and commands. The computer keyboard also has a numeric keypad for performing fundamental mathematical operations. Further, most electric typewriters have an automatic  return.  Operating  systems  of  software programs have a similar feature, called wraparound, that returns the cursor to the next line once the typist finishes the current line. Before operating a computer, take time to read the instructions. In a short time, you should be able to successfully  operate  your  computer  and  become familiar with the word-processing programs available to you. Since computers are delicate tools, care should be exercised when computers must be moved or cleaned. A sudden drop on the deck or the use of certain cleaning agents may be harmful to the computer or may render the unit unusable. When a computer must be moved or cleaned, refer to the owner’s manual that is provided by the manufacturer. Word  Processing  (Typing) A graduate of the AZ “A” school is not required to take a typing performance test. Successful completion of the approved typing course is a prerequisite for graduation from the AZ “A” school. However, AZ strikers  (non-“A”  school  graduates)  must  still  complete the typing performance test before they can participate in the advancement examination for AZ3. The  typing  performance  test  is  usually administered by an activity’s (station, ship) education services  officer,  and  may  be  taken  on  either  a typewriter or a personal computer. The test should be available at least once per quarter. The division chief petty officer (CPO) or petty officer first class, however, may be able to get the test administered on other occasions if they request it at the appropriate time. AZ strikers are required to type 20 words per minute.  For  the  striker  who  has  had  prior  typing experience, a small amount of practice will result in 20 words per minute proficiency in just a little time. Therefore, when the AZ striker feels that he or she can type 20 words per minute consistently, the striker should   ask   the   division   petty   officer   for   the performance test. Once the striker passes the typing performance test and has the test results entered in his or her service record, the minimum typing requirement for advancement has been met, and the test does not have to be taken again. Computers  and  word  processors  have  all  but replaced the typewriter. Therefore, the typewriter will not be discussed in this chapter. Q2. Q3. Q4. You should know the names and rates or rank of everyone in the office when you start work in the maintenance administration division. (True or False) What is the word-processing equivalent of an electronic typewriter’s automatic return? The input device and the output device are two basic components of a computer. What is the third basic component of a computer? CLASSIFIED  INFORMATION LEARNING OBJECTIVE: State the three classifications  of  classified  material  and  the security  and  handling  of  each. AZs  handle  all  types  of  publications  and correspondence, some of which may be classified. Therefore, you will need to know about classified material. In this section of the manual, we will discuss security   classifications,   safeguarding   classified material, correct handling, storage, and transmission of classified  material.  For  detailed  information concerning the security of classified information, refer to the Department of the Navy (DON) Information Security Program (ISP) Regulation, SECNAVINST 5510.36. CLASSIFICATIONS There   are   three   approved   classifications   of classified   material:   Top   Secret,   Secret,   and Confidential. FOR OFFICIAL USE ONLY is not an approved  classified  material  classification.  Storage requirements,   method   of   transmission,   and safeguarding  procedures  vary  for  each  classification. The   following   is   a   brief   description   of   each classification. Top Secret. A Top Secret designation is applied to material  that,  if  disclosed,  could  be  reasonably expected to cause exceptionally grave damage to national security. Examples include material on armed hostilities against the U. S. or its allies or disruption of foreign relations vitally that affect national security. Secret. A secret designation is applied to material that, if disclosed, could reasonably be expected to cause 2-5
