LDTs are the siblings of the Global Descriptor Table (GDT), and each define up to 8192 memory segments accessible to programs - note that unlike the GDT, the zeroeth entry is a valid entry, and can be used like any other LDT entry. Also note that unlike the GDT, the LDT cannot be used to store certain system entries: TSSs or LDTs. Call Gates ...
Differentiated instruction and assessment, also known as differentiated learning or, in education, simply, differentiation, is a framework or philosophy for effective teaching that involves providing all students within their diverse classroom community of learners a range of different avenues for understanding new information (often in the same classroom) in terms of: acquiring content ...
Geometric dimensioning and tolerancing, GD&T; Global Descriptor Table, an x86 data structure; Global distance test, to compare proteins; Ground Data Terminal; GDT or Gerätedatentransfer, a medical data format; see xDT
The LDT is used for a particular task. But it can be shared between the tasks as well. GDT contains a descriptor pointing to the base of the LDT. The register LDTR points to the LDT descriptor within the GDT. A LDT descriptor copy is stored in 64-bit register in CPU. (fig)
Technology integration is defined as the use of technology to enhance and support the educational environment. Technology integration in the classroom can also support classroom instruction by creating opportunities for students to complete assignments on the computer rather than with normal pencil and paper.

A segment register called the task register (TR) holds a segment selector that points to a valid TSS segment descriptor which resides in the GDT (a TSS descriptor may not reside in the LDT). Therefore, to use a TSS the following must be done by the operating system kernel: Create a TSS descriptor entry in the GDT
The descriptors may be either interrupt gates, trap gates or, for 32-bit protected mode only, task gates. Interrupt and trap gates point to a memory location containing code to execute by specifying both a segment (present in either the GDT or LDT) and an offset within that segment. The only difference between trap and interrupt gates is that ...
Computers in the classroom include any digital technology used to enhance, supplement, or replace a traditional educational curriculum with computer science education. As computers have become more accessible, inexpensive, and powerful, the demand for this technology has increased, leading to more frequent use of computer resources within ...
