LaCie Ethernet Disk Glossary Gebruikershandleiding pagina 59 Backup – (1) The act of creating at least one additional copy of data onto a different (and safe) storage device from where it can be retrieved at a later time if needed. (2) A copy of a file, directory, or volume on a separate storage device from the original, for the purposes of retrieval in case the original is erased, damaged, or destroyed. Bit – The smallest measure of computerized data, either a 1 or a 0. Eight bits equal one byte, or one character. Block – A very small section of the storage media comprised of one or more sectors. A block is the smallest amount of space allocated on a drive for data storage. By default, a sec- tor of data consists of 512 bytes. Buffer – RAM cache that is faster than the data that is being delivered. Buffers are used so data may be stored and deliv- ered to the receiving item as it is needed. Bus – Electronic links that enable data to flow between the processor, RAM and extension cables (peripherals). Byte – A sequence of adjacent binary digits, or bits, consid- ered as a unit, 8 bits in length. There are 8 bits in 1 byte. See also MB (Megabyte) or GB (Gigabyte). Cache, -ing – This is an area of electronic storage (usually RAM) set aside to store frequently used data from electrome- chanical storage (hard drives, floppy disks, CD/DVD-ROM, tape cartridges, etc.) Therefore, storing frequently used data in RAM can enhance your system’s overall response to disk- intensive operations significantly. Configuration – When talking about a PC, configuration is understood to be the sum of the internal and external compo- nents of the system, including memory, disk drives, the key- board, the video subsystem and other peripherals, such as the mouse, modem or printer. The configuration also implies software: the operating system and various device managers (drivers), as well as hardware settings and options set by the user via configuration files. Controller – This is a component or an electronic card (re- ferred to in this case as a “controller card”) that enables a computer to communicate with or manage certain peripher- als. The controller manages the operation of the peripheral associated with it, and links the PC bus to the peripheral via a ribbon cable inside the PC. An external controller is an expansion card which fills one of the free slots inside your PC and which enables a peripheral (CD-ROM drive, scanner or printer, for instance) to be connected to the computer. Cross-platform – Term that refers to a device that is able to be operated by both Mac and Windows operating systems. Data Stream – The flow of data that accomplishes a task, usually related to moving data from storage to computer RAM or between storage devices. Digital – Discrete information that can be broken down to zero or one bits. Driver (peripheral manager) – A software component that enables the computer system to communicate with a periph- eral. Most peripherals will not operate correctly – if at all – if the appropriate drivers are not installed on the system. DHCP (Dynamic Host Configuration Protocol) – This is a communications protocol that allows network administrators to centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization’s network. Using IP, each computer that connects to the Internet must have a unique IP address. Ethernet – A LAN technology, based on the IEEE 802.3 standard. The most common Ethernet systems are 10BASE- T, which provides transmission speeds up to 10Mb/s, and 100BASE-T (also known as Fast Ethernet), which provides transmission speeds up to 100Mb/s, and Gigabit which pro- vides 1000Mb/s (see also Gigabit Ethernet below). File System – Links the physical map of a disc to its logical structure. Thanks to the file system, users and computers can easily display path, directories and files recorded onto the disc. FTP (File Transfer Protocol) – This is a standard Internet protocol that uses the Internet’s TCP/IP protocols to exchange files between computers on the Internet. It is commonly used to download programs and other files to a computer from a server. Firmware – Permanent or semi-permanent instructions and data programmed directly into the circuitry of a program- 16. Glossary

Used for controlling the operation of the computer or tape drive. Distinct from the software, which is stored in random access memory and can be altered. Folder – A list created on a disk to store files. Creating folders and sub-folders enables you to organize the storage of your files in a logical, hierarchical manner so that you can find and manage them more easily. Format, -ting, -ted – This is a process where a device is prepared to record data. In this process, the hard disk writes special information onto its own recording surfaces into areas (blocks) that are ready to accept user data. Since this opera- tion causes all current user data stored on the hard disk to be lost, this is an infrequent operation that usually only hap- pens at the factory that created the hard disk. It is unusual for something to happen to a hard disk that requires the end-user to initially perform this operation. Gigabit – Unit of measure, commonly used to express the amount of data in one second between two points. E.g. in the term Gigabit Ethernet – 1 gigabit per second (1 Gbps) equals 1 billion bits per second and is equivalent to 1000Mb/s. GB (GigaByte) – This value is normally associated with data storage capacity. Basically, it means a thousand million or a billion bytes. In fact, it equals 1,073,741,824 bytes (or 1,024 x 1,024 x 1,024). Hardware – Physical components of a computer system, in- cluding the computer itself and peripherals such as printers, modems, mice, etc. Host Bus Adapter (HBA) – A printed circuit board that installs in a standard microcomputer and an interface between the device controller and the computer. Also called a controller. http (Hypertext Transfer Protocol) – This is the set of rules for exchanging files (i.e. text, images, audio, video, etc.) on the World Wide Web. http is an application protocol, rela- tive to the TCP/IP suite of protocols that form the basis for exchanging information on the Internet. Initialize, -ed, Initialization – After a hard drive (or other storage device) is formatted and partitioned, some special data needs to be written to it that helps the Mac and Windows create files and save data. The process is called initialization. This process, like formatting, causes all user data on the stor- age device to be lost. Internet – A collection of networks whose users communicate with one another. Each communication carries the address of the source and destination networks and the particular machine within the network associated with the user or host computer on each end. IP (Internet Protocol) – This is the protocol that controls how data is sent from one computer to another on the Internet. IP Address – This is a number (either 32-bit for Internet Pro- tocol Version 4, or 128-bit for Internet Protocol Version 6) that identifies each sender or receiver of information that is sent in packets across the Internet. Interface – The protocol data transmitters, data receivers, logic and wiring that link one piece of computer equipment to anoth- er, such as a hard drive to an adapter or an adapter to a system bus. Protocol means a set of rules for operating the physical interface, such as: do not read or write before the drive is ready. I/O (Input/Output) – Refers to an operation, program or device whose purpose is to enter data into or to extract data from a computer. Kb (Kilobit) – Equivalent to 1,000 bits. Kb/s – Kilobits per second. 480Kb/s is equal to 60KB/s. KB (KiloByte) – Basically, this means 1,000 bytes, but it is actually 1,024 bytes. KB/s – Kilobytes per second. A means of measuring throughput. LAN (Local Area Network) – A group of computers and associated devices that share a common communication line and typically share the resources of a single processor or serv- er within a small geographic area. Mb (Megabit) – Equivalent to 1,000,000 bits. Mb/s – Megabits per second. A means of measuring through- put. 480Mb/s is equal to 60MB/s. MB (Megabyte) – Basically means one million bytes, but is actually 1,024 Kilobytes or 1,024 x 1,024 bytes, which equals 1,048,576 bytes. MB/s – Megabytes per second. A means of measuring throughput. Media – The material or device used to store information in a storage subsystem, such as a tape cartridge, CD, DVD or disk drive.

Networks can interconnect with other networks and contain subnetworks. Operating System (OS) – Software that controls the assign- ment and use of hardware resources such as memory, proces- sor time, disk space and peripherals. An operating system is the basis on which software (applications) run. Windows, Mac OS and UNIX are among the most common. Overwrite – To write data on top of existing data thus erasing the original data. Partition, -ing – After formatting, the hard drive is not yet ready to store files. It must be divided into sections that will contain special information required for a Mac or PC to oper- ate and other sections that will contain the files. This process of dividing up the hard drive is called partitioning. A partition is just one section of the hard drive that will contain either special data put there by Silverlining or other files and data. Peripheral – A generic term applied to printers, scanners, mice, keyboards, serial ports, graphics cords, disk drives and other computer subsystems. This type of peripheral often re- lies on its own control software, known as a peripheral driver. Port, hardware – A connection component (SCSI port, for example) that enables a microprocessor to communicate with a compatible peripheral. Port, number – Used to identify a specific process to which an Internet or other network message is to be forwarded when it arrives at a server. Port, software – A memory address that identifies the physi- cal circuit used to transfer information between a micropro- cessor and a peripheral. Protocol – In IT terminology, this describes the special set of rules that end points in a telecommunication connection use when they communicate. RAM (Random Access Memory) – Generally referred to as a computer’s “memory.” An integrated circuit memory chip that allows information to be stored and retrieved by a mi- croprocessor or controller. The information can be stored or accessed in any order, and all storage locations are equally accessible. Seek Time – The amount of time (in thousandths of a second, or milliseconds) that it takes a hard drive’s read/write head to move to a specific location on the disk. Average seek, then, is the average of a large number of random samplings all over the disk. Seek time is CPU independent, meaning that seek time is the same for a disk drive, whether it is attached to a computer or not. Software – In a nutshell, software is a set of instructions for the computer. A set of instructions to perform a particular task is called a program. There are two main types of soft- ware: system software (an operating system such as Mac OS or Windows) which controls the operation of the computer and application software (programs such as Word or Excel) which enable users to perform tasks such as word processing, spreadsheet creation, graphics, etc. Storage – In computers, any equipment in which information may be kept. PCs generally use disk units and other external storage media (diskettes, CD-ROMs, magnetic disks, etc.) for permanent storage of information. Striping – Spreading data evenly over multiple disk drives to enhance performance. Data striping can be performed on a bit, byte or block basis for optimum application performance. Subnetwork (Subnet) – This is a separate, identifiable part of a network, such as all of the computers at one geographic loca- tion, in one building or on the same local area network. Subnets make it possible to have an organization’s network connected to the Internet with a single, shared network address. Transfer Rate – The rate at which the drive sends and receives data from the controller. Transfer rates for reading data from the disk drive may not be the same as the transfer rate for writ- ing data to the disk drive. Transfer rates are CPU dependent, meaning that regardless of how great a transfer rate your drive is capable of, the actual transfer rate can only be as fast as the slowest of your hard drive and computer. TCP/IP (Transmission Control Protocol/Internet Proto- col) – This is the basic communication protocol of the Inter- net. TCP/IP uses the client/server model of communication, in which a client (a computer user) requests and is provided a service (such as a Web pagina) by another computer (a server) in the network. Volume – A desktop mountable storage area, may be a parti- tion of a hard drive, a removable disk or a cartridge. Typically measured in Megabytes or Gigabytes. UDP (User Datagram Protocol) – This is a communications protocol that allows a limited amount of service when mes- sages are exchanged between computers in a network that
Page: 4
LaCie Ethernet Disk Glossary Gebruikershandleiding pagina 62 uses the Internet Protocol (IP). UDP uses the IP to get a data unit (a datagram) from one computer to another, but does not sequence the packets that the data arrives in. UDP also provides port numbers to distinguish different user requests, and an optional checksum capability to verify that the data arrived intact. Utility – Software designed to perform maintenance tasks on the system or its components. Examples include backup pro- grams, programs to retrieve files and data on disk, programs for preparing (or formatting) a disk or and resource editors.
