Active Directory (AD) is a directory service that Microsoft developed for Windows domain networks and is included in most Windows Server operating systems as a set of processes and services. An AD domain controller 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


BC (Business Continuity)

Business continuity encompasses a loosely defined set of planning, preparatory and related activities which are intended to ensure that an organization’s critical business functions will either continue to operate despite serious incidents or disasters that might otherwise have interrupted them, or will be recovered to an operational state within a reasonably short period



Content Management System. iManage, Worldox, DM, NetDocuments


A colocation center (also spelled co-location, collocation, colo, or coloc) is a type of data center where equipment, space, and bandwidth are available for rental to retail customers. Colocation facilities provide space, power, cooling, and physical security for the server, storage, and networking equipment of other firms—and connect them to a variety of telecommunications and network service provider

Community cloud

A community cloud in computing is a collaborative effort in which infrastructure is shared between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third-party and hosted internally or externally. The costs are spread over fewer users than a public cloud (but more than a private cloud), so only some of the cost savings potential of cloud computing are realized


Cascading Style Sheets (CSS) is a style sheet language used for describing the look and formatting of a document written in a markup language. While most often used to style web pages and user interfaces written in HTML and XHTML, the language can be applied to any kind of XML document, including plain XML, SVG and XUL. CSS is a cornerstone specification of the web and almost all web pages use CSS style sheets to describe their presentation.



Dynamic Host Configuration Protocol (DHCP) is a standardized networking protocol used on Internet Protocol (IP) networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services. With DHCP, computers request IP addresses and networking parameters automatically from a DHCP server, reducing the need for a network administrator or a user to configure these settings manually


In telephony, the demarcation point is the point at which the public switched telephone network ends and connects with the customer’s on-premises wiring. It is the dividing line which determines who is responsible for installation and maintenance of wiring and equipment — customer/subscriber, or telephone company/provider


Document Management System. See CMS


The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It translates easily memorized domain names to the numerical IP addresses needed for the purpose of locating computer services and devices worldwide. The Domain Name System is an essential component of the functionality of the Internet.

DR (Disaster Recovery)

Disaster recovery (DR) involves a set of policies and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster. Disaster recovery focuses on the IT or technology systems supporting critical business functions,[2] as opposed to business continuity, which involves keeping all essential aspects of a business functioning despite significant disruptive events. Disaster recovery is therefore a subset of business continuity



In cryptography, encryption is the process of encoding messages or information in such a way that only authorized parties can read it. n an encryption scheme, the message or information, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, large computational resources and skill are required. Encryption may be define as “in transit” and “at rest”


Enterprise resource planning (ERP) is a business management software—usually a suite of integrated applications—that a company can use to collect, store, manage and interpret data from many business activities, including:- Product planning, cost and development, Manufacturing or service delivery, Marketing and sales, Inventory management, Shipping and payment.


VMware ESX is an enterprise-level computer virtualization product offered by VMware. ESX is a component of VMware’s larger offering, VMware Infrastructure, which adds management and reliability services to the core server product. VMware is replacing the original ESX with ESXi. ESX is apparently derived from “Elastic Sky X”, but with rare exceptions this doesn’t appear in official VMware material.


Microsoft Exchange Server is calendaring software, a mail server and contact manager developed by Microsoft. It is a server program that runs on Windows Server and is part of the Microsoft Servers line of products. Exchange has about 65% market share across all organizations.



AKA File and Print – A server whose role is sharing files and print queues to end-users


Adobe Flash (formerly called Macromedia Flash and Shockwave Flash) is a multimedia and software platform used for creating vector graphics, animation, games and rich Internet applications (RIAs) that can be viewed, played and executed in Adobe Flash Player. Flash is frequently used to add streamed video or audio players, advertisement and interactive multimedia content to web pages, although usage of Flash on websites is declining.



The gigabit is a multiple of the unit bit for digital information or computer storage. The prefix giga (symbol G) is defined in the International System of Units (SI) as a multiplier of 109 (1 billion, short scale),[1] and therefore 1 gigabit = 109bits = 1000000000bits. The gigabit has the unit symbol Gbit or Gb. Using the common byte size of 8 bits, 1 Gbit is equal to 125 megabytes (MB) or approximately 119 mebibytes (MiB).


The gigabyte (/ˈɡɪɡəbaɪt/ GIG-ə-byt ) is a multiple of the unit byte for digital information. The prefix giga means 109 in the International System of Units (SI), therefore one gigabyte is 1000000000bytes. The unit symbol for the gigabyte is GB. I GB = 1000MB



A hard disk drive (HDD) is a data storage device used for storing and retrieving digital information using rapidly rotating disks (platters) coated with magnetic materia


Te Health Insurance Portability and Accountability Act of 1996 (HIPAA) was enacted by the United States Congress and signed by President Bill Clinton in 1996. It has been known as the Kennedy–Kassebaum Act or Kassebaum-Kennedy Act after two of its leading sponsors. Title II of HIPAA defines policies, procedures and guidelines for maintaining the privacy and security of individually identifiable health information as well as outlining numerous offenses relating to health care and sets civil and criminal penalties for violations. In January 2013, HIPAA was updated via the Final Omnibus Rule. Included in changes were updates to the Security Rule and Breach Notification portions of the HITECH Act. The greatest changes relate to the expansion of requirements to include business associates, where only covered entities had originally been held to uphold these sections of the law.


HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. It is the fifth revision of the HTML standard (created in 1990 and standardized as HTML 4 as of 1997)[2] and, as of December 2012, is a candidate recommendation of the World Wide Web Consortium (W3C).[3] Its core aims have been to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.). HTML5 is intended to subsume not only HTML 4, but also XHTML 1 and DOM Level 2 HTML.



Java is a set of several computer software products and specifications from Oracle Corporation that provides a system for developing application software and deploying it in a cross-platform computing environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones on the low end, to enterprise servers and supercomputers on the high end. While less common, Java applets are sometimes used to provide improved and secure functions while browsing the World Wide Web on desktop computers.



A local area network (LAN) is a computer network that interconnects computers within a limited area such as a home, school, computer laboratory, or office building, using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines.



The megabit is a multiple of the unit bit for digital information or computer storage. The prefix mega (symbol M) is defined in the International System of Units (SI) as a multiplier of 106 (1 million),[1] and therefore 1 megabit = 106bits = 1000000bits = 1000 kilobits. The megabit has the unit symbol Mb or Mbit. 1 Mb = 1000Kb


The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB, but sometimes MByte is used. The unit prefix mega is a multiplier of 1000000 (106) in the International System of Units (SI). Therefore one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities. 1 MB = 1000 KB


Multiprotocol Label Switching (MPLS) is a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels identify virtual links (paths) between distant nodes rather than endpoints. MPLS can encapsulate packets of various network protocols. MPLS supports a range of access technologies, including T1/E1, ATM, Frame Relay, and DSL. Usually used for Point to Point communication between geographically disparate offices



Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to a heterogeneous group of clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often manufactured as a computer appliance – a specialized computer built from the ground up for storing and serving files – rather than simply a general purpose computer being used for the role


Non-public Personal Information



The Payment Card Industry Data Security Standard (PCI DSS) is a proprietary information security standard for organizations that handle cardholder information for the major debit, credit, prepaid, e-purse, ATM, and POS cards.


The petabyte (symbol PB) is 1015 bytes of digital information. A related unit, the pebibyte (PiB), using a binary prefix, is 10245 = 250 = 1125899906842624bytes, more than 12% larger.

1 PB = 1000000000000000B = 1015bytes = 1000terabytes.

The prefix peta indicates the fifth power of 1000 and means 1015 in the International System of Units (SI), and therefore 1 petabyte is one quadrillion (short scale) bytes. The world’s effective capacity to exchange information through two-way telecommunication networks was 281 petabytes of information in 1986, 471 petabytes in 1993, 2,200 petabytes in 2000, and 65,000 petabytes in 2007 (this is the informational equivalent to every person exchanging 6 newspapers per day)


Protected health information (PHI) is any information about health status, provision of health care, or payment for health care that can be linked to a specific individual. May include any part of a patents medical record or payment history


The Primary Rate Interface (PRI) is a standardized telecommunications service level within the Integrated Services Digital Network (ISDN) specification for carrying multiple DS0 voice and data transmissions between a network and a user. PRI is the standard for providing telecommunication services to offices. It is based on the T-carrier (T1) line in the US and Canada, and the E-carrier (E1) line in Europe. The T1 line consists of 24 channels, while an E1 has 32.

Private cloud

Private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party, and hosted either internally or externally.[1] Undertaking a private cloud project requires a significant level and degree of engagement to virtualize the business environment, and requires the organization to reevaluate decisions about existing resources

Public cloud

A cloud is called a “public cloud” when the services are rendered over a network that is open for public use. Public cloud services may be free or offered on a pay-per-usage model.[64] Technically there may be little or no difference between public and private cloud architecture


Recovery point

Used within the backup industry as a “point in time” backup. Recovery points may be joined together to create a synthetic full backup. Typically, a full backup is created then individual recovery points are created nightly.


Used within the backup industry as a means to copy data backed up locally to a data center or colocation facility for the purposes of disaster recovery



A storage area network (SAN) is a dedicated network that provides access to consolidated, block level data storage. SANs are primarily used to enhance storage devices, such as disk arrays, tape libraries, and optical jukeboxes, accessible to servers so that the devices appear like locally attached devices to the operating system. A SAN typically has its own network of storage devices that are generally not accessible through the local area network (LAN) by other devices


Serial Attached SCSI (SAS) is a point-to-point serial protocol that moves data to and from computer storage devices such as hard drives and tape drives. SAS replaces the older Parallel SCSI (Small Computer System Interface, pronounced “scuzzy”) Most servers sold today are equiped with SAS hard drives


Small Computer System Interface (SCSI, /ˈskʌzi/ SKUZ-ee)[1] is a set of standards for physically connecting and transferring data between computers and peripheral devices. The SCSI standards define commands, protocols and electrical and optical interfaces. SCSI is most commonly used for hard disks and tape drives, but it can connect a wide range of other devices, including scanners and CD drives, although not all controllers can handle all devices.


The Session Initiation Protocol (SIP) is a signaling communications protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP) networks. Most carriers, i.e. AT&T, Windstream, Cbeyond, etc. can deliver VoIP service using this method


In computer systems, a snapshot is the state of a system at a particular point in time. The term was coined as an analogy to that in photography. It can refer to an actual copy of the state of a system or to a capability provided by certain systems.


SQL or /ˈsiːkwəl/; Structured Query Language is a special-purpose programming language designed for managing data held in a relational database management system (RDBMS). Originally based upon relational algebra and tuple relational calculus, SQL consists of a data definition language and a data manipulation language. The scope of SQL includes data insert, query, update and delete, schema creation and modification, and data access control. Although SQL is often described as, and to a great extent is, a declarative language (4GL), it also includes procedural elements.


A solid-state drive (SSD) (also known as a solid-state disk or electronic disk, though it contains no actual disk) is a data storage device using integrated circuit assemblies as memory to store data persistently. SSDs have no moving (mechanical) components. This distinguishes them from traditional electromechanical magnetic disks such as hard disk drives (HDDs) or floppy disks, which contain spinning disks and movable read/write heads. Compared with electromechanical disks, SSDs are typically more resistant to physical shock, run silently, have lower access time, and less latency



Digital Signal 1 (DS1, sometimes DS-1) is a T-carrier signaling scheme devised by Bell Labs. DS1 is a widely used standard in telecommunications in North America and Japan to transmit voice and data between devices. DS1 is the logical bit pattern used over a physical T1 line; however, the terms “DS1″ and “T1″ are often used interchangeably.


The terabyte is a multiple of the unit byte for digital information. The prefix tera represents the fourth power of 1000, and means 1012 in the International System of Units (SI), and therefore one terabyte is one trillion (short scale) bytes. The unit symbol for the terabyte is TB. 1 TB = 1000000000000bytes = 1012bytes = 1000gigabytes.
