Sector (Athletics)

The landing area for the shot put and softball throw.

Sector (Computer Technology)

This is a piece of a track of a hard drive or other disk media. Each track is split up into groups of sectors.

Sector (DVD)

A logical or physical group of bytes recorded on the disc-the smallest addressable unit. A DVD sector contains 38,688 bits of channel data and 2048 bytes of user data.

Sector (DVD and CD)

A logical or physical group of bytes recorded on the disc—the smallest addressable unit. A DVD sector contains 38,688 bits of channel data and 2048 bytes of user data.

Sector (Data Recovery)

The basic storage unit on a hard disk. On most modern hard disks, sectors are 512 bytes each, four sectors make up a cluster.

Sector (Energy)

See Energy-use sectors.

Sector (Finance)

Used to characterize a group of securities that are similar with respect to maturity, type, rating, industry, and/or coupon.

Sector (Fundraising)

A distinct part or division of the economy. We commonly divide the economy into three sectors: the private (business), public (government), and the non-profit (or voluntary) sector. See also:Nonprofit Sector, Private Sector, Public Sector, Third Sector, Voluntary Sector

Sector (Grantmaking)

A distinct part or division of the economy. We commonly divide the economy into three sectors: the private (business), public (government), and the non-profit (or voluntary) sector. See also:Nonprofit Sector, Private Sector, Public Sector, Third Sector, Voluntary Sector

Sector (Hard Drive Recovery)

A 512-byte packet of data in EIDE and SCSI hard drives. This is the smallest amount of data that can be read or written to the drive from the host interface. On Macintosh and Unix drives, sectors are usually grouped into blocks or logical blocks that function as the smallest data unit permitted. Since these blocks are often defined as a single sector, the terms block and sector are sometimes used interchangeably in this context. (Note: The meaning of the term block in connection with the physical configuration of the disk is different from its meaning at the system level. (See also block and cluster.)

Sector (Investment)

A distinct subset of a market, society, industry, or economy, whose components share similar characteristics.

Sector (Linux, Red Hat)

The primary measuring unit of a storage disk upon which data is stored.

Sector (Police)

One of three geographic divisions within a police district, comprising three to five beats.

Sector (RAID Drive Recovery)

A 512-byte packet of data in EIDE and SCSI hard drives. This is the smallest amount of data that can be read or written to the drive from the host interface. On Macintosh and Unix drives, sectors are usually grouped into blocks or logical blocks that function as the smallest data unit permitted. Since these blocks are often defined as a single sector, the terms block and sector are sometimes used interchangeably in this context. (Note: The meaning of the term block in connection with the physical configuration of the disk is different from its meaning at the system level. (See also block and cluster.)

Sector (Storage Media)

On a PC hard drive, the minimum segment of track length that can be assigned to store information. On Macintosh and UNIX drives, sectors usually are grouped into blocks or logical blocks that function as the smallest data unit permitted. Since these blocks often are defined as a single sector, the terms block and sector are sometimes used interchangeably in this context. (Note: The usage of the term block in connection with the physical configuration of the disk is different from its meaning at the system level.)

Sector (Technology)

A portion of the data storage area on a disk. A disk is divided into sides (top and bottom), tracks (rings on each surface), and sectors (sections of each ring). Sectors are the smallest physical storage units on a disk and are of fixed size; typically, they are capable of holding 512 bytes of information apiece.

Sector (Trigonometry)

A portion of a circle enclosed by a central angle and its subtended arc.
