Glossary
Garbage A procedure that automatically determines what memory a program is no
collection longer using and recycles it for other use. This is also known as automatic
storage (or memory) reclamation.
TI GRAPH An optional accessory that links a calculator to a personal computer to
LINK enable communication.
Group Used to identify several calculators as a single unit. This allows the group of
certificate calculators, or unit, to be assigned a new program license using only one
certificate (instead of requiring a new unique unit certificate for each
calculator in the group). The group certificate must be used in conjunction
with the unit certificate.
Hexadecimal Base 16 system, which is often used in computing. Counting is as follows:
{0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F}.
High-level Any programming language that resembles English. This makes it easier for
language humans to understand. Unfortunately, a computer cannot understand it
unless it is compiled into machine language. See also low-level language.
Examples of high-level languages are C/C++, Pascal, FORTRAN, COBOL,
Ada, etc.
IDE Integrated Development Environment.
Immediate An addressing mode where the data value is contained within the instruction
instead of being loaded from somewhere else. For example, in LD A, 17, 17
is an immediate value. In LD A, B, the value in B is not immediate, because
it is not written into the code.
Interpreted A language that is changed from source code to machine language in real-
language time. Examples are BASIC (for the PC and the TI version, TI BASIC) and
JavaScript. Interpreted languages are often much simpler, which helps
beginners get started and allows experienced programmers to write code
quickly. Interpreted languages, however, are restricted in their capability,
and they run slower.
Instruction A command that tells the processor to do something, for example, add two
numbers or get some data from the memory.
I/O port An input/output interface from the calculator to the external world. It allows
communication with other units, CBL and CBR , and personal computers.
LCD port An output port that drives LCD display device for use on overhead
projectors. Available on the teacher's ViewScreen calculator only.
Low-level Any programming language that does not look like English but is still to be
language understandable by people. It uses words like add to replace machine
language instructions like 110100. See also high-level language.
Machine Any programming language that consists of 1's and 0's (called binary),
language which represents instructions. A typical machine instruction could be
110100, which means add two numbers together.
Mac Link MacIntosh resident link software that can communicate with the calculator.
