Block Started by Symbol (BSS) was a pseudo-op in UA-SAP (United Aircraft Symbolic Assembly Program), the assembler developed in the mid-1950's for the IBM 704 by Roy Nutt, Walter Ramshaw, and others at United Aircraft Corporation. An assembler is a computer program for translating assembly language — essentially, a mnemonic representation of machine language — into object code. ... The IBM 704, the first mass-produced computer with floating point arithmetic hardware, was introduced by IBM in April, 1956. ...

The BSS pseudo-op was later incorporated into FAP (FORTRAN Assembly Program), the standard IBM assembler for the IBM 709, 7090 and 7094 computers. It defined its label and reserved space for a given number of words. FORTRAN Assembly Program (FAP) was a macro assembler for the IBM 709, 7090, and 7094 computers of the 1950s and 60s. ... International Business Machines Corporation (IBM, or colloquially, Big Blue) (NYSE: IBM) (incorporated June 15, 1911, in operation since 1888) is headquartered in Armonk, NY, USA. The company manufactures and sells computer hardware, software, and services. ... The IBM 700/7000 series was a series of incompatible large scale (mainframe) computer systems made by IBM through the 1950s and early 1960s. ...

Most modern assemblers produce a BSS section in their output object module containing all reserved uninitialized space.

BSS is also defined as;

BSS - Basic Service Set in the IEEE 802.11-1999 Standard. A BSS is the basic building block of an IEEE 802.11 wireless LAN. The most basic BSS is two STAs in IBSS mode. In infrastructure mode, a basic BSS consists of at least one STA and one Access Point (AP). IEEE 802. ... IEEE 802. ... STA has the following meanings: STA is an abbreviation for STAtion and is a basic networking term. ... IBSS - Independant Basic Service Set. ... STA has the following meanings: STA is an abbreviation for STAtion and is a basic networking term. ... A wireless access point (WAP or AP) is a device that connects wireless communication devices together to create a wireless network. ...

In infrastructure mode, groups of BSSs can be abstracted as an ESS when the BSSs share a common network name or SSID. The term ESS: In telecommunications refers to an electronic switching system. ... A service set identifier (SSID) is a code attached to all packets on a wireless network to identify each packet as part of that network. ...
