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
