XYZ was a laboratory model of a utility machine; the ZAM-2 series was created on the basis of this computer. [ 1 ] The logical organization was modeled on the simplified IBM 701 , but the electronics were based on the dynamic flip-flops of the M-20 machine, requiring twice as few lamps.
The Lütjens-class destroyer was a modification of the Charles F. Adams class for the Bundesmarine (the Navy of West Germany). It differed from the Charles F. Adams class in the layout of the crew accommodations, the location of the bow sonar, a second large aerial mast and different funnels. Lütjens (D185) (scrapped) Mölders (D186) (Museum ship)
A "Hello, World!"program is usually a simple computer program that emits (or displays) to the screen (often the console) a message similar to "Hello, World!".A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.
On several computer systems from Sun Microsystems, the command "xyzzy" is used to enter the interactive shell of the U-Boot bootloader. [6] Early versions of Zenith Z-DOS (a re-branded variant of MS-DOS 1.25) had the command "xyzzy" which took a parameter of "on" or "off". Xyzzy by itself would print the status of the last "xyzzy on" or "xyzzy ...
A computer program written in an imperative language. Imperative languages specify a sequential algorithm using declarations, expressions, and statements: [52] A declaration introduces a variable name to the computer program and assigns it to a datatype [53] – for example: var x: integer; An expression yields a value – for example: 2 + 2 ...
The following is a common set of access specifiers: [10] Private (or class-private) restricts access to the class itself. Only methods that are part of the same class can access private members. Protected (or class-protected) allows the class itself and all its subclasses to access the member. Public means that any code can access the member by ...
Homogeneous coordinates are ubiquitous in computer graphics because they allow common vector operations such as translation, rotation, scaling and perspective projection to be represented as a matrix by which the vector is multiplied. By the chain rule, any sequence of such operations can be multiplied out into a single matrix, allowing simple ...
CDC 3000 by University of Oslo's Joint Computer Installation at Kjeller; TOPS-10 by Swedish National Defence Research Institute (FOA) These implementations were ported to a wide range of platforms. The TOPS-10 implemented the concept of public, protected, and private member variables and procedures, that later was integrated into Simula ...
