Active Data: Information residing on the direct access storage media of computer systems, which is readily visible to the operating system and/or application software with which it was created and immediately accessible to users without restoration, modification, or reconstruction (i.e., word processing and spreadsheet files, programs and files used by the computer's operating system).
Active Records: Records related to current, ongoing or in process activities and are referred to on a regular basis to respond to day‑to‑day operational requirements. An active record resides in native application format and is accessible for purposes of business processing with no restrictions on alteration beyond normal business rules.
Admissible: Admissible evidence is evidence that is acceptable or allowable in court.
Application: A collection of one or more related software programs that enable a user to enter, store, view, modify or extract information from files or databases. The term is commonly used in place of "program," or "software." Applications may include word processors, Internet browsing tools and spreadsheets.
Archival Data: Information that is not directly accessible to the user of a computer system but that the organization maintains for long‑term storage and record keeping purposes. Archival data may be written to removable media such as a CD, magneto‑optical media, tape or other electronic storage device, or may be maintained on system hard drives in compressed formats (i.e., data stored on backup tapes or disks, usually for disaster recovery purposes).
Archive/Electronic Archive: Archives are long-term repositories for the storage of records. Electronic archives preserve the content, prevent or track alterations and control access to electronic records.
Attachment: A record or file associated with another record for the purpose of storage or transfer. There may be multiple attachments associated with a single "parent" or "master" record. The attachments and associated record may be managed and processed as a single unit. In common use, this term refers to a file (or files) associated with an e‑mail for transfer and storage as a single message unit. Because, in certain circumstances, the context of the attachment (for example, the parent e‑mail and its associated metadata) can be important, an organization should consider whether its policy should authorize or restrict the disassociation of attachments from their parent records.
Attribute: A characteristic of data that sets it apart from other data, such as location, length, or type. The term “attribute” is sometimes used synonymously with "data element" or "property."
ASCII (Acronym for American Standard Code): ASCII is a code that assigns a number to each key on the keyboard. ASCII text does not include special formatting features and, therefore, can be exchanged and read by most computer programs.
Author/Originator: The author of a document is the person, office or designated position responsible for its creation or issuance. In the case of a document in the form of a letter, the author or originator is usually indicated on the letterhead or by signature. In some cases, the software application producing the document may capture the author's identity and associate it with the document.
Backup: To create a copy of data as a precaution against the loss or damage of the original data is to create a “Backup”. Most users backup some of their files, and many computer networks utilize automatic backup software to make regular copies of some or all of the data on the network. Some backup systems use digital audio tape (DAT) as a storage medium.
Backup Data: Information that is not presently in use by an organization and is routinely stored separately upon portable media, to free up space and permit data recovery in the event of disaster.
Backup Tape: Backup or disaster recovery tapes are portable media used to store data that is not presently in use by an organization to free up space but still allow for disaster recovery.
Backup Tape Recycling: The process whereby an organization's backup tapes are overwritten with new backup data, usually on a fixed schedule (i.e., the use of nightly backup tapes for each day of the week with the daily backup tape for a particular day being overwritten on the same day the following week; weekly and monthly backups being stored offsite for a specified period of time before being placed back in the rotation).
Bandwidth: The amount of information or data that can be sent over a network connection in a given period of time. Bandwidth is usually stated in bits per second (bps), kilobits per second (kbps), or megabits per second (mps).
Basic De‑duplication: De-duplication is performed on a select and limited basis, such as for file names and types, and is usually based on the hash value of the entire electronic document.
Bates Production Number: A bates production number is a tracking number assigned to each page of each document in the production set.
Binary: Mathematical base 2, or numbers composed of a series of zeros and ones. Since zeroes and ones can be easily represented by two voltage levels on an electronic device, the binary number system is widely used in digital computing.

Byte: Eight bits. A byte is a collection of bits used by computers to represent a character (i.e., "a", "1", or "&"). A "megabyte" is one million bytes or eight million bits or a "gigabyte" is one billion bytes or eight billion bits.
1 gigabyte = 1,000 megabytes
1 terabyte = 1,000 gigabytes
Cache: A type of computer memory that temporarily stores frequently used information for quick access.
CD‑ROM: Data storage medium that uses compact discs to store about 1,500 floppy discs worth of data.
Chain‑of‑Custody: A process used to maintain and document the chronological history of electronic evidence. A chain‑of‑custody ensures that the data presented is "as originally acquired" and has not been altered prior to admission into evidence. RenewData maintains an electronic chain‑of‑custody link between all electronic data and its original physical media throughout the production process.
Coding: Document coding is the process of capturing case‑relevant information (i.e. author, date authored, date sent, recipient, date opened, etc.) from a paper document.
Compression: A technology that reduces the size of a file. Compression programs are valuable to network users because they help save both time and bandwidth.
Computer Forensics: The use of specialized techniques for recovery, authentication, and analysis of electronic data when a case involves issues relating to reconstruction of computer usage, examination of residual data, and authentication of data by technical analysis or explanation of technical features of data and computer usage. Computer forensics requires specialized expertise that goes beyond normal data collection and preservation techniques available to end‑users or system support personnel.

Data Extraction: The process of removing files and meta‑data from backup tapes.
De‑duplication (De‑Duping): The process of comparing electronic records based on their characteristics and removing duplicate records from the data set.
Deleted Data: Data that, in the past, existed on the computer as live data and which has been deleted by the computer system or end‑user activity. Deleted data remains on storage media in whole or in part until it is overwritten by ongoing usage or "wiped" with a software program specifically designed to remove deleted data. Even after the data itself has been wiped, directory entries, pointers, or other metadata relating to the deleted data may remain on the computer.
Deleted File: A file with disk space that has been designated as available for reuse. The deleted file remains intact until it has been overwritten with a new file.
Deleted Files and Data: Recoverable information from deleted files and data may be stored in unallocated or slack space on a computer hard drive.

Each party is required to cooperate with the other to the extent required by the relevant rules of civil procedure.
Distributed Data: That information belonging to an organization which resides on portable media and non‑local devices such as home computers, laptop computers, floppy disks, CD‑ROMs, personal digital assistants ("PDAs"), wireless communication devices (i.e., Blackberry), zip drives, Internet repositories such as e‑mail hosted by Internet service providers or portals, Web pages, and the like. Distributed data also includes data held by third parties such as application service providers and business partners.
Document: Fed. R. Civ. P. 34(a) defines a document as "including writings, drawings, graphs, charts, photographs, phone records, and other data compilations." In the electronic discovery world, a document also refers to a collection of pages representing an electronic file. E‑mails, attachments, databases, word documents, spreadsheets, and graphic files are all examples of electronic documents.
Dynamic De‑duplication: RenewData's proprietary dynamic de‑duplication technology handles large volumes of information and ensures that unique meta‑data and original content are stored only once. This dynamic de‑duplication process is executed as the data flows off the tapes, avoiding large and expensive processing and storage requirements.
Electronic Discovery: The discovery of electronic documents and data including e‑mail, Web pages, word processing files, computer databases, and virtually anything that is stored on a computer. Technically, documents and data are "electronic" if they exist in a medium that can only be read through the use of computers. Such media include cache memory, magnetic disks (such as computer hard drives or floppy disks), optical disks (such as DVDs or CDs), and magnetic tapes.
Electronic Discovery Reference Model (EDRM) Glossary: The EDRM Glossary for electronic discovery is a working compilation of key terms gathered from member organizations of the EDRM, including RenewData, and which is now available online from the EDRM web site. EDRM Glossary
Electronic Evidence: According to Black's law dictionary, evidence is "any species of proof, or probative matter, legally presented at the trial of an issue, by the act of the parties and through the medium of witnesses, records, documents, exhibits, concrete objects, etc. for the purpose of inducing belief in the minds of the court or jury as to their contention." Electronic information (like paper) generally is admissible into evidence in a legal proceeding.
Electronic Mail Message: Commonly referred to as "e‑mail" or “email”, an electronic mail message is a document created or received via an electronic mail system, including brief notes, formal or substantive narrative documents, and any attachments, such as word processing and other electronic documents, which may be transmitted with the message.
Electronic Record: Information recorded in a form that requires a computer or other machine to process it and that otherwise satisfies the definition of a record.
Email: The whole of an electronic document containing the message envelope and message content (attachments, etc.).
Email Message Store: A top most email message store is the location in which an email system stores its data. For instance, an Outlook PST (personal storage folder) is a type of top most file that is created when a user's Microsoft Outlook mail account is set up. Additional Outlook PST files for that user can be created for backing up and archiving Outlook folders, messages, forms and files. Similar to a filing cabinet, which is not considered part of the paper documents contained in it, a top most store generally is not considered part of a family.

File: A collection of data of information stored under a specified name on a disk.
File Extension: A tag of three or four letters, preceded by a period, which identifies a data file's format or the application used to create the file. File extensions can streamline the process of locating data. For example, if one is looking for incriminating pictures stored on a computer, one might begin with the .gif and .jpg files.
File Server: When several or many computers are networked together in a LAN situation, one computer may be utilized as a storage location for files for the group. File servers may be employed to store email, financial data, word processing information or to back‑up the network.
File Sharing: One of the key benefits of a network is the ability to share files stored on the server among several users.
Filtering: Electronic filtering of emails and files for privilege or by keyword, file type or name. Filtering removes files that don't fit the search criteria and reduces the volume of data that requires further investigation.
Firewall: A set of related programs that protect the resources of a private network from users from other networks.
Floppy: An increasingly rare storage medium consisting of a thin magnetic film disk housed in a protective sleeve.
Forensically Sound Procedures: Procedures used for acquiring electronic information in a manner that ensures it is "as originally discovered" and is reliable enough to be admitted into evidence. Such procedures are defined in part by the US Department of Justice publication "Searching and Seizing Computers and Obtaining Electronic Evidence in Criminal Investigations."
Format: The internal structure of a file, which defines the way it is stored and used. Specific applications may define unique formats for their data (i.e., "MS Word document file format"). Many files may only be viewed or printed using their originating application or an application designed to work with compatible formats. Computer storage systems commonly identify files by a naming convention that denotes the format (and therefore the probable originating application) (i.e., "DOC" for Microsoft Word document files; "XLS" for Microsoft Excel spreadsheet files; "TXT" for text files; and "HTM" (for Hypertext Markup Language (HTML) files such as Web pages). Users may choose alternate naming conventions, but this may affect how the files are treated by applications.

"Load" may also refer to the process of transferring data from mounted media to another media or to an online system.
Native Environment: The original configuration (software, passwords, server configuration, etc.) of a backup tape or email system (i.e. Microsoft Exchange).
Native File: A file saved in the format of the original application used to create the file. Dealing with native files can minimize expensive per‑page costs for the traditional TIFF and/or PDF processing and will maximize the relevant information available from the file.
Native Format: Electronic documents have an associated file structure defined by the original creating application. This file structure is referred to as the "native format" of the document. Because viewing or searching documents in the native format may require the original application (i.e., viewing a Microsoft Word document may require the Microsoft Word application), documents are often converted to a standard file format (i.e., tiff) as part of electronic document processing.
Nesting: Document nesting occurs when one document is inserted within another document (i.e., an attachment is nested within an email; graphics files are nested within a Microsoft Word document).

Residual data includes (1) data found on media free space; (2) data found in file slack space; and (3) data within files that has functionally been deleted, in that it is not visible using the application with which the file was created, without use of undelete or special data recovery techniques.
Restore: To transfer data from a backup medium (such as tapes) to an online system, often for the purpose of recovery from a problem, failure, or disaster. Restoration of archival media is the transfer of data from an archival store to an online system for the purposes of processing (such as query, analysis, extraction or disposition of that data). Archival restoration of systems may require not only data restoration but also replication of the original hardware and software operating environment. Restoration of systems is often called "recovery".
Router: A piece of hardware that routes data from a local area network (LAN) to a phone line.
Sampling: Usually (but not always) refers to the process of statistically testing a data set for the likelihood of relevant information. It can be a useful technique in addressing a number of issues relating to litigation, including decisions as to which repositories of data should be preserved and reviewed in a particular litigation, and determinations of the validity and effectiveness of searches or other data extraction procedures. Sampling can be useful in providing information to the court about the relative cost burden versus benefit of requiring a party to review certain electronic records.
Sandbox: A network or series of networks that are not connected to other networks.
Scanning: The process of converting a hard copy paper document into a digital image for use in a computer system. After a document has been scanned, it can be reviewed using field and full‑text searching, instant document retrieval, and a complete range of electronic document review options.
