The UNIX operating system is a set of programs that act as a link between the computer and the user. Users communicate with the kernel through a program known as the shell. The shell is a command-line interpreter; it translates commands entered by the user and converts them into a language that is understood by the kernel. Students will demonstrate a mastery of the course materials and concepts within class discussions.

About the Revised Syllabus 1 2. Since then many advancements have taken place in the field of Information Technology. Consequently it has become necessary to revise the syllabus.

В одном Чатрукьян был абсолютно уверен: если шеф узнает, что в лаборатории систем безопасности никого нет, это будет стоить молодому сотруднику места. Чатрукьян посмотрел на телефонный аппарат и подумал, не позвонить ли этому парню: в лаборатории действовало неписаное правило, по которому сотрудники должны прикрывать друг друга. В шифровалке они считались людьми второго сорта и не очень-то ладили с местной элитой. Ни для кого не было секретом, что всем в этом многомиллиардном курятнике управляли шифровальщики.

Basics of OS, Unix and Shell Programming

 Господи Иисусе! - шумно вздохнул Хейл.  - Похоже, Стратмор здорово промыл тебе мозги. Ты отлично знаешь, что ФБР не может прослушивать телефонные разговоры произвольно: для этого они должны получить ордер. Этот новый стандарт шифрования означал бы, что АНБ может прослушивать кого угодно, где угодно и когда угодно. - Ты прав - и так и должно быть! - сурово отрезала Сьюзан.  - Если бы ты не нашел черный ход в Попрыгунчике, мы могли бы взломать любой шифр, вместо того чтобы полагаться на ТРАНСТЕКСТ.

КЛУШАР - ЛИКВИДИРОВАН Он улыбнулся. Часть задания заключалась в немедленном уведомлении. Но сообщать имена жертв… с точки зрения человека в очках в металлической оправе, это было признаком особой элегантности стиля. Его пальцы снова задвигались, приводя в действие сотовый модем, и перед глазами появилось: СООБЩЕНИЕ ОТПРАВЛЕНО ГЛАВА 26 Сидя на скамейке напротив городской больницы, Беккер думал о том, что делать. Звонки в агентства услуг сопровождения ничего не дали. Коммандер, недовольный необходимостью говорить по линии, не защищенной от прослушивания, попросил Дэвида не звонить, пока кольцо не окажется в его руках.

Вдруг это вирус. Ты раньше говорил что-то про вирус. - Черт возьми, Мидж! - взорвался Джабба.  - Я сказал, что вируса в шифровалке. Тебе надо лечиться от паранойи. В трубке повисло молчание. - Мидж… - Джабба попробовал извиниться.

 Мидж.  - Джабба засопел и сделал изрядный глоток.  - Если бы в игрушке Стратмора завелся вирус, он бы сразу мне позвонил. Стратмор человек умный, но о вирусах понятия не имеет. У него в голове ничего, кроме ТРАНСТЕКСТА. При первых же признаках беды он тут же поднял бы тревогу - а в этих стенах сие означает, что он позвонил бы.  - Джабба сунул в рот кусочек сыра моцарелла.

А теперь - за работу. ГЛАВА 12 Дэвиду Беккеру приходилось бывать на похоронах и видеть мертвых, но на этот раз его глазам открылось нечто особенно действующее на нервы. Это не был тщательно загримированный покойник в обитом шелком гробу.
