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

The Ping of Death uses a ping system utility to create an IP packet that exceeds the maximum 65,536 bytes of data allowed by the IP specification. The oversize packet is then sent to an unsuspecting system. Systems may crash, hang, or reboot when they receive such a maliciously crafted packet. This attack is not new, and all OS vendors have fixes in place to handle the oversize packets.

1). Memorizing - this is absolutely the worst way to keep track of material. People are preoccupied with trying to remember the words to say and not the ideas behind the words (or with the audience). As a result, normal voice inflection disappears. With memorizing, mental blocks become inevitable. With memorizing it is not a matter of will you forget; it's a matter of WHEN!

2). Reading from complete text - Listening to someone read a speech or presentation is hated by most people. People say, If that's all they were going to do is read th ....etc

A speech needs time to grow. Prepare for weeks, sleep on it, dream about it and let your ideas sink into your subconscious. Ask yourself questions, write down your thoughts, and keep adding new ideas. As you prepare every speech ask yourself the following questions.

In one concise sentence, what is the purpose of this speech?
1) Who is the audience? What is their main interest in this topic?
2) What do I really know and believe about this topic as it relates to this audience?
3) What additional research can I do?
4) What are the main ....etc

1) Take into consideration that you were most likely asked to speak because you have knowledge about the topic.
2) The most important thing --- don't panic. If you can, find a copy of the presentation handouts and scan them, writing down the main topics for each portion of the presentation.
3) This allows you to quickly look at the content of the presentation.
4) If the original speaker planned to use slides, quickly skim each slide and write down the key points.
5) Do not concern yourself with the exact words on the slide.
6) If the sli ....etc

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 t ....etc
