Windows Domain
A Windows domain is a form of a computer network in which all user accounts, computers, printers and other Principal (computer security), security principals, are registered with a central database located on one or more clusters of central computers known as Domain controller (Windows), domain controllers. Authentication takes place on domain controllers. Each person who uses computers within a domain receives a unique user account that can then be assigned access to resources within the domain. Starting with Windows Server 2000, Active Directory is the Windows component in charge of maintaining that central database.Northrup, Tony''Introducing Microsoft Windows 2000 Server'' Microsoft Press, 1999. The concept of Windows domain is in contrast with that of a workgroup (computer networking), workgroup in which each computer maintains its own database of security principals. Configuration Computers can connect to a domain via LAN, Wide area network, WAN or using a Virtual private ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Active Directory
Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Directory was used only for centralized domain management. However, Active Directory eventually became an umbrella title for a broad range of directory-based identity-related services. A server running the Active Directory Domain Service (AD DS) role is called a domain controller. It authenticates and authorizes all users and computers in a Windows domain type network, assigning and enforcing security policies for all computers, and installing or updating software. For example, when a user logs into a computer that is part of a Windows domain, Active Directory checks the submitted username and password and determines whether the user is a system administrator or normal user. Also, it allows management and storage of information, provides authentication and authorization mec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Hosting Service
An Internet hosting service is a service that runs servers connected to the Internet, allowing organizations and individuals to serve content or host services connected to the Internet. A common kind of hosting is web hosting. Most hosting providers offer a combination of services - e-mail hosting, website hosting, and database hosting, for example. DNS hosting service, another type of service usually provided by hosting providers, is often bundled with domain name registration. Dedicated server hosts, provide a server, usually housed in a datacenter and connected to the Internet where clients can run anything they want (including web servers and other servers). The hosting provider ensures that the servers have Internet connections with good upstream bandwidth and reliable power sources. Another popular kind of hosting service is shared hosting. This is a type of web hosting service, where the hosting provider provisions hosting services for multiple clients on one physical ...

Small And Medium-sized Enterprises
Small and medium-sized enterprises (SMEs) or small and medium-sized businesses (SMBs) are businesses whose personnel and revenue numbers fall below certain limits. The abbreviation "SME" is used by international organizations such as the World Bank, the European Union, the United Nations, and the World Trade Organization (WTO). In any given national economy, SMEs sometimes outnumber large companies by a wide margin and also employ many more people. For example, Australian SMEs makeup 98% of all Australian businesses, produce one-third of the total GDP (gross domestic product) and employ 4.7 million people. In Chile, in the commercial year 2014, 98.5% of the firms were classified as SMEs. In Tunisia, the self-employed workers alone account for about 28% of the total non-farm employment, and firms with fewer than 100 employees account for about 62% of total employment. The United States' SMEs generate half of all U.S. jobs, but only 40% of GDP. Developing countries tend to have a lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CardDAV
vCard Extensions to WebDAV (CardDAV) is an address book client/server protocol designed to allow users to access and share contact data on a server. The CardDAV protocol was developed by the IETF and was published as in August 2011. CardDAV is based on WebDAV, which is based on HTTP, and it uses vCard for contact data. History CardDAV was proposed as an open standard for contact management in August 2011. It became known as a synchronization protocol in iOS 7, among other things, and is now also supported by Gmail, where it replaces the no longer supported (by Google) ActiveSync standard. In October 2013, the standard received an update that made it possible to capture higher-resolution contact images and achieve lower data consumption. Specification The specification has been proposed as a standard by IETF as thRFC 6352in August 2011 by C. Daboo from Apple Inc. Implementations Server-side The following products implement the ''server''-side portion of the CardDAV protocol: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CalDAV
Calendaring Extensions to WebDAV, or CalDAV, is an Internet standard allowing a client to access and manage calendar data along with the ability to schedule meetings with users on the same or on remote servers. It lets multiple users in different locations to share, search and synchronize calendar data. It extends the WebDAV (HTTP-based protocol for data manipulation) specification and uses the iCalendar format for the calendar data. The access protocol is defined by . Extensions to CalDAV for scheduling are standardized as . The protocol is used by many important open-source applications. History The ''CalDAV'' specification was first published in 2003 as an Internet Draft submitted to the Internet Engineering Task Force (IETF) by Lisa Dusseault. In March 2007, the ''CalDAV'' specification was finished and published by the IETF as RFC 4791, authored by Cyrus Daboo (Apple), Bernard Desruissaux (Oracle), and Lisa Dusseault (CommerceNet). ''CalDAV'' is designed for implementatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Message Access Protocol
In computing, the Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection. IMAP is defined by . IMAP was designed with the goal of permitting complete management of an email box by multiple email clients, therefore clients generally leave messages on the server until the user explicitly deletes them. An IMAP server typically listens on port number 143. IMAP over SSL/TLS (IMAPS) is assigned the port number 993. Virtually all modern e-mail clients and servers support IMAP, which along with the earlier POP3 (Post Office Protocol) are the two most prevalent standard protocols for email retrieval. Many webmail service providers such as Gmail and Outlook.com also provide support for both IMAP and POP3. Email protocols The Internet Message Access Protocol is an application layer Internet protocol that allows an e-mail client to access email on a remote mail server. The curre ...

Post Office Protocol
In computing, the Post Office Protocol (POP) is an application-layer Internet standard protocol used by e-mail clients to retrieve e-mail from a mail server. POP version 3 (POP3) is the version in common use, and along with IMAP the most common protocols for email retrieval. Purpose The Post Office Protocol provides access via an Internet Protocol (IP) network for a user client application to a mailbox (''maildrop'') maintained on a mail server. The protocol supports download and delete operations for messages. POP3 clients connect, retrieve all messages, store them on the client computer, and finally delete them from the server. This design of POP and its procedures was driven by the need of users having only temporary Internet connections, such as dial-up access, allowing these users to retrieve e-mail when connected, and subsequently to view and manipulate the retrieved messages when offline. POP3 clients also have an option to leave mail on the server after download. By contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simple Mail Transfer Protocol
The Simple Mail Transfer Protocol (SMTP) is an Internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages. User-level email clients typically use SMTP only for sending messages to a mail server for relaying, and typically submit outgoing email to the mail server on port 587 or 465 per . For retrieving messages, IMAP (which replaced the older POP3) is standard, but proprietary servers also often implement proprietary protocols, e.g., Exchange ActiveSync. SMTP's origins began in 1980, building on concepts implemented on the ARPANET since 1971. It has been updated, modified and extended multiple times. The protocol version in common use today has extensible structure with various extensions for authentication, encryption, binary data transfer, and internationalized email addresses. SMTP servers commonly use the Transmission Control Protocol on port number 25 (for plaintext) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
