Introduction to paging:
Memory is divided into fixed size chunks; FRAMES
Process is divided into fixed size chunks;PAGES
A frame can hold one page of data
Physical address space of a process need not be contiguous
Very limited internal fragmentation
No external fragmentation

Paging is one of the memory-management schemes by which a computer can store and retrieve data from secondary storage for use in main memory. In the paging memory-management scheme, the operating ....etc

More Info About PAGING TECHNOLOGY

the developing of paging technology is given below :;--

The commercial paging technology proved useful for remotely controlling substation and feeder devices. At an industry meeting on automated meter reading, a CP&L attendee inquired about the possibility of using the design for a control function on an electric utility system. After general agreement that such an application was feasible, a request for information was submitted to 12 companies that produced traditional capacitor controllers. O ....etc

Sequential device activator or process control timer circuits have wide area of applications and its complexity varies depending upon the device to be activated. Here is a simple sequential device activator circuit using IC 555 and relay as activator. As we all know that IC555 has some unique capabilities to act as a timer and oscillator. Here we employ the IC 555 as a timer to activate three device sequentially given specific timings for each device. The main advantage of this circuit is you can increase the number of devices to be activated j ....etc

Power supply is an electronic circuit that is used for providing the electrical power to appliances or loads suchas computers,machines,and so on. These electrical and electronic loads require various forms of power at different ranges and with different characteristics. So, for this reason the power is converted into the required forms (with desired qualities) by using some power electronic converters or power converters.

Electrical and electronic loads work with various forms of power supplies, such as AC power supply, AC- to-DC power suppl ....etc

with the aid of a diagram explain dynamic packet filtering

On the Internet, packet filtering is the process of passing or blocking packets at a network interface based on source and destination addresses, ports, or protocols. The process is used in conjunction with packet mangling and Network Address Translation (NAT). Packet filtering is often part of a firewall program for protecting a local network from unwanted intrusion.In a software firewall, packet filtering is done by a program called a packet filter. The packet filter examines the hea ....etc

Introduction

In computer operating systems, demand paging is an application of virtual memory. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it (i.e., if a page fault occurs). This is an example of lazy loading techniques.

The compressed ROM file system (or cramfs) is a free read-only Linux file system designed for simplicity and space-efficiency. It is mainly used in embedded systems and small-footprint systems. Unlike a compressed image of a ....etc
