SEARCH THE BUSINESS GLOSSARY
computer that can perform an operation on an entire array of numbers in a single step; also known as an array processor. Cray supercomputers are vector processors. They have machine instructions that can (for example) add each entry of arrayA to the corresponding entry of array B and store the result in the corresponding entry of array C. Contrast
term referring to the underwriting process that involves securities being proposed for public distribution. The phrase used is "in the pipeline." The entire underwriting process, including registration with the Securities and Exchange Commission, must be completed before a security can be offered for public sale. Underwriters attempt to have several securities issues waiting in the pipeline so that the issues can be sold as soon as market conditions become favorable. In the municipal bond market, the pipeline is called the "Thirty Day Visible Supply" in the Bond Buyer newspaper.
the design and internal structure of digital computers.
Fundamentally, a computer is a machine that can store instructions and execute them. Thus, it consists of two major parts,
The CPU spends its time retrieving instructions from memory and doing whatever those instructions say. Each instruction is a pattern of bits (binary ones and zeroes, represented by electrical on and off signals). When the instruction reaches the CPU, the CPU must decode recognize) it and activate the appropriate functional unit within the CPU in order to carry out the instruction. Functional units include adders, multipliers, circuits to compare bit patterns, etc., all of which are built from logic gates (for an example, see
The CPU contains

Programmers normally do not write CPU instructions. Instead, they write programs in a high-level language such as BASIC, C, or Pascal, and use a
