Operating Modes

1. Real Mode - 20 MB of segmented memory adress space, direct software access to BIOS routines and peripheral hardware, no concept of memory protection or multitasking. 80286 and further start with real mode.

2. Protected Mode - expanding addressable physical memory to 16 MB and addressable virtual memory to 1 GB. Provided protected memory. This is done by using segment registers only for storing an index to segment table. Global Descriptor Table (GDT) & Local Descriptor Table (LDT) each giving access to 64 KB of memory. The segment table provided a 24-bit base address, which can be added to desired offset to create an absolute address. 80386 introduced support in protected mode for paging which made it possible to use paged virtual memory.

Bipartite and semihamiltonian graphs

Bipartite Graph: A graph is bipartite if its vertex set can be partitioned into two subsets X and Y so that every edge has one end in X and one end in Y; such a partition (X,Y) is called bipartition of the graph, and X and Y its parts. ex.- Notation: We denote a bipartite graph G with bipartition (X,Y) by G[X,Y]. Complete Bipartite Graph: If G[X,Y] is simple and every vertex in X is joined to every vertex in Y, then G is called a Complete Bipartite graph. ex.- Semi-Hamiltonian Graph: A semi-Hamiltonian graph is a graph that contains a Hamiltonian path, but not a Hamilton cycle. Hamiltonian Path: A Hamiltonian path in an undirected or directed graph is a path which visits each vertex exactly once. ex.- C-A-D-B-E is a Hamiltonian path Hamiltonian Cycle: A Hamiltonian cycle or a Hamiltonian Circuit is a Hamiltonian path which is a cycle. This post will be useful in understanding a question: "The nabhi kamal grapg is:" (A)Bipartite graph (B)Semi-...

Accessibility : An Important consideration in software development

What is Accessibility? Accessibility is a very important piece of consideration in today's market. It means the quality of being able to be reached or entered. Accessibility focuses on how a physically or mentally disabled person accesses or benefits from a site, system or application.  Conformance with accessibility guidelines while developing a web page or an app is important. What does accessibility mean for software development? Accessibility isn't about taking away functionality or making things difficult for the software development team. It is about making sure all possible users have a way to use the system.  How do information architects and web designers/developers design web pages to be compatible with assistive devices is an important aspect when thinking about accessibility. What does accessibility mean for software testing? Accessibility Testing checks if a product is accessible to the people having disabilities. We need to understand ...

Android 102

This post is in continuation with an earlier post : Android 101 1. Common attributes used in views and viewgroups: -layout_width -layout_height -layout_marginTop -layout_marginBottom -layout_marginLeft -layout_marginRight -layout_gravity: specifies how child views are positioned -layout_weight: specifies how much of the extra space in the layout should be allocated to the view -layout_x -layout_y 2. LinearLayout: arranges views in a single column or a single row. Child views can be arranged either vertically or horizontally. 3.AbsoluteLayout: enables you to specify the exact location of its children using layout_x and layout_y. AbsoluteLayout has been deprecated since android 1.5 4.TableLayout: groups views into rows and columns. You use <TableRow> element to designate a row in the table. Each row can contain one or more views. Each view you place within a row forms a cell. The width of each column is determined by the largest width of each cell in that column. 5....
