The document provides information on installing and configuring an Exchange mail server. It defines what a mail server is and lists some common mail servers like Exchange, Domino, Sendmail, etc. It then describes how to install Exchange server on a domain, and how to create different types of mail-enabled recipients like users, contacts, groups and public folders in Exchange. It also provides steps to hide a mailbox in Exchange 2000.

We present an experiment designed to reveal some of the key features
necessary for conveying creature motion. Humans can reliably identify animals shown in minimal form using Point Light Display
(PLD) representations, but it is unclear what information they use when doing so. The ultimate goal for this research is to find recognizable traits that may be communicated to the viewer through motion, such as size and attitude and then to use that information to develop a new way of creating and managing animation and animation controls. The aim of this study was to investigate whether viewers use similar visual information when asked to identify or describe animal motion PLDs and full representations. Participants were shown 20 videos of 10 animals, first as PLD and then in full resolution. After each video, participants were asked to select descriptive
traits and to identify the animal represented. Species identification
results were better than chance for six of the 10 animals when shown PLD. Results from the eye tracking show that participants’
gaze was consistently drawn to similar regions when viewing the PLD as the full representation.
The document provides an overview of social media and its uses. It discusses popular social media sites like Twitter, Facebook, LinkedIn, and others. It outlines how social media allows organizations to connect with consumers, replace traditional advertising, and give everyone a voice. The document also provides examples of how to measure return on investment from social media and the importance of understanding objectives when selecting social media platforms.

Youth are increasingly at risk of gambling addiction due to influences from family, friends, and a desire for identity and thrill-seeking. Males, Aboriginal people, and those with lower education levels have even higher risks. Gambling addictions can transfer from video games and are linked to behaviors seen in alcoholism like seeking pleasure, relief from depression, and altered moods. The addiction progresses through phases from initial winning to desperation and hopelessness as losses mount and more extreme acts are taken to recover losses or debts, sometimes including crime. Prevention and treatment are difficult due to denial of problems and a lack of obvious signs, making addictions harder to identify in youth.
This document provides an overview of 12 verb tenses in English, including the simple present, present progressive, simple past, past progressive, present perfect, present perfect progressive, past perfect, past perfect progressive, future, future progressive, future perfect, and future perfect progressive tenses. Each tense is defined in terms of how it expresses time and duration of events, such as habits, ongoing actions, completed actions, actions before or after other events. Examples are given to illustrate the proper usage of each verb tense.
This document discusses the simple present tense in English. It provides examples of common verbs used in the simple present tense to describe everyday and repeated activities. It also covers spelling rules for third person singular verbs, how to form negatives and questions in the simple present tense, and includes exercises for students to practice.

9. FTP FTP (FileTransferProtocol) — протокол, предназначенный для передачи файлов в компьютерных сетях, посроенный по принципу "клиент-сервер". FTP позволяет подключаться клиенту к серверам FTP, просматривать содержимое каталогов, скачивать файлы с сервера или загружать файлы на сервер 9
10. FTP Протокол FTP относится к протоколам прикладного уровня и для передачи данных использует транспортный протокол TCP. Команды и данные, в отличие от большинства других протоколов передаются по разным портам. Порт 20 используется для передачи данных, порт 21 для передачи команд. 10
11. Пример взаимодействия клиента и сервера FTP 220 FTP server ready. USER ftp //Анонимус 230Login successful. PASV 227 Entering Passive Mode (192,168,254,253,233,92)//Клиент должен открыть соединение на переданный IP LIST 150 Here comes the directory listing. //Сервер передает список файлов в директории 226Directory send OK. CWD incoming 250 Directory successfully changed. PASV 227 Entering Passive Mode (192,168,254,253,207,56) STOR gyuyfotry.avi 150 Ok to send data. //Клиент передает содержимое файла 226File receive OK. QUIT 221 Goodbye 11
12. Безопасность передачи данных по протоколу FTP Протокол не шифруется, при аутентификации передаёт логин и пароль открытым текстом. Процесс нешифрованной авторизации проходит в несколько этапов: Установка TCP-соединения с сервером (обычно на 21 порт) Посылка команды USER логин Посылка команды PASS пароль Если к серверу разрешён анонимный доступ (как правило, лишь для загрузки данных с сервера), то в качестве логина используется ключевое слово «anonymous» или «ftp», а в качестве пароля — адрес электронной почты: USER anonymous PASS someone@email Чтобы предотвратить перехват трафика, необходимо использовать протокол шифрования данных SSL, который поддерживается многими современными FTP-серверами и некоторыми FTP-клиентами. 12
13. FXP FXP (FileeXchangeProtocol) — способ передачи файлов между двумя FTP-серверами напрямую, не закачивая их на свой компьютер . При FXP-сессии клиент открывает два FTP-соединения к двум разным серверам, запрашивая файл на первом сервере, указывая в команде PORT IP-адрес второго сервера. 13
19. Сервер FTP, в отличиии от BitTorrent, представляет единую физическую реализацию, скорость передачи данныхи надежность которого зависит от скорости и надежности канала до сервера.
