Maskable Interrupts– Processors have to interrupt mask register that allows enabling and disabling of hardware interrupts. Every signal has a bit placed in the mask register. If this bit is set, an interrupt is enabled & disabled when a bit is not set, or vice versa. Signals that interrupt ...
Name and briefly describe three different uses for interrupts. Describe three methods to implement security on wireless networks. For a public wireless solution, name three security methods that are not practical and why. (a) Define the system bus. (b) In a computer system, how they affect ...
Nearly all modern computers implement some form of the stored program architecture, making it the single trait by which the word "computer" is now defined. By this standard, many earlier devices would no longer be called computers by today's definition, but are usually referred to as such in...
Network Architecture defines the communications products and services, which ensure that the various components can work together. In the early days of data communication systems, the majority of communications were between the DTE and the hostcomputer. Therefore, transmission control procedures were alone...
Types of Assemblers There are two main types of assemblers used in computer programming: Single-pass assembler: A single-pass assembler, also known as a one-pass translation, performs a complete scan of the source program input to the assembler or its equivalent representation and translates each...
Pins 10 – 17:This port also serves some other functions like interrupts, timer input, control signals for external memory interfacing Read and Write. This is a quasi bidirectional port with internal pull-up. Pin 9:It is a RESET pin, used to set the 8051 microcontrollers to its initial val...
What is the difference between hardware interrupts and software interrupts and give examples of situations where each is used. Explain the difference between hardware and software. Discuss in detail several effective local security prac...
The development tool drag-and-drop features provide a very rapid mechanism to generate data bound UI from the name and type data source table and/or field. To avoid any loss of productivity or interrupts in developer thought processes, the drag-and-drop experience, in general, facilitates dropp...
An “event” is any action or occurrence to which a computer system might respond, including hardware interrupts, software interrupts, exceptions, faults, traps, aborts, machine checks, assists, and debug events. Upon receiving an event, the processor's event handling mechanism causes the ...
Picture segmentation techniques can have in common that the segment boundaries interrupt certain prediction mechanisms. For example, in some video coding technologies and standards, a segment boundary interrupts in-picture prediction mechanisms, such as motion vector prediction, intra prediction, and so fo...
