In the graphic, Host A has reached 50% completionin sending a 1 KB Ethernet frame to Host D when Host Bwishes to transmit its own frame to Host C. What mustTeam Fortress 2ServersGet your affordablehigh quality voiceand game servertoday!GaloreGameServers.ComHost B do?Host B can transmit immediately since it is connected on itsown cable segment.Host B must wait to receive a CSMA transmission from thehub, to signal its turn.Host B must send a request signal to Host A by transmittingan interframe gap.Host B must wait until it is certain that Host A hascompleted sending its frame.Free PeopleSearchFree PeopleSearch.

Характеристики
Тип файла PDF
PDF-формат наиболее широко используется для просмотра любого типа файлов на любом устройстве. В него можно сохранить документ, таблицы, презентацию, текст, чертежи, вычисления, графики и всё остальное, что можно показать на экране любого устройства. Именно его лучше всего использовать для печати.
Например, если Вам нужно распечатать чертёж из автокада, Вы сохраните чертёж на флешку, но будет ли автокад в пункте печати? А если будет, то нужная версия с нужными библиотеками? Именно для этого и нужен формат PDF - в нём точно будет показано верно вне зависимости от того, в какой программе создали PDF-файл и есть ли нужная программа для его просмотра.
