If the message portion of a frame contains 640 bits, SDLC has a beginning flag (8 bits), an address (8 bits), a control field (8 bits), a frame check sequence (assume we use a CRC-32 with 32 bits), and an ending flag (8 bits). Calculate the efficiency of this synchronous transmission and complete TE1. Next, calculate the efficiency using a frame that contains 720 bits with the same overhead and complete TE2. Which one is more efficient

Write an application that allows a user to enter the names and birthdates of up to 10 friends. continue to prompt the user for names and birthdates until the user enters the sentinel value “zzz” for a name or has entered 10 names, whichever comes first. when the user is finished entering names, produce a count of how many names were entered, and then display the names. in a loop, continuously ask the user to type one of the names and display the corresponding birthdate or an error message if the name has not been previously entered. the loop continues until the user enters “zzz” for a name. save the application as birthdayreminder. java.

Step 1: choose your topics review the project milestone reflections you submitted for modules 1 through 4. choose the one major idea or concept from each module that you feel most applies to your life. in addition, choose an important concept from module 5 that applies to your life. step 2: write your guidebook for each module: write a catchy headline that clearly and concisely sums up your chosen idea or concept write a brief explanation that includes a description of the concept, why it is important, and how it can be applied to your life to make a positive impact choose an exciting, powerful, or engaging image that illustrates your concept remember, you are writing one for each module, so you will have a total of five headlines, five descriptions, and five images. step 3: design your guidebook choose a format to present your digital guidebook. there are many 21st century tools available for creating and submitting your work in the online environment. for more information on tools your school uses, contact your instructor or visit the web 2.0 tools area.
