Web Caching : The Storage Mechanism

Level 3 or L3 cache is dedicated memory that works hand-in-hand with L1 and L2 cache to increase computer performance. L1, L2 and L3 cache are computer processing unit CPU caches, verses other kinds of caches in the system such as hard disk cache. CPU cache accommodates the needs of the microprocessor by anticipating data requirements so that processing instructions are delivered without interruption. CPU cache is quicker than random access memory (RAM), and is intended to stop bottlenecks in performance.

i) Memory : cache server (holds recently acesed web pages in its RAM, for spedier aces

Client requests file from the cold cache of the server and stores file on its disk.

These components can be combined in a large variety of configuration for very simple caching needs, like increasing the performance of the database access for a single application to the client, which very complex needs such as for grid

The benefit of virtually indexed physically tagged cache is that the translation of virtual address and cache lookup can happen in parallel:

4) Which type of application benefits the most by bypassing write cache? Justify your answer.

Local storage, which is sometimes referred to as DOM Storage, is a simple persistent key-value storage directly in the browser. An important advantage of local storage is that it is natively implemented in browsers, which means that it is available even when external plug-ins are not. It is better than cookies, can store more memory size. It also more secure and safety. But the local storage is not support older version of browser. We also need to send client information manually.

Cache is a volatile form of storage meaning when the computer is turned off, then the data is lost. Cache cost a lot of money to make meaning it has got a higher cost per byte than ram or flash storage. The reason cache is used for storing frequently instructions near or on the CPU is because it's faster than ram and has less latency, but has a higher capacity than registers at a lower but still high cost compared to other types of storage. In conduction is that cache is a high speed form of temporary storage, which acts as a buffer between the ram and the CPU, which stores frequently used instructions which removes the speed decrease from using the system buses and has low latency and cost less than registers and has a higher

These updates can be performed immediately or in a lazy manner. In a multiprocessor system, different processors might be caching the same memory location in its local caches. When updates are made, the other cached locations need to be invalidated or updated. In distributed systems, consistency of cached memory values is not an issue. However, consistency problems might arise when a client caches file data.

This research report was to understand the background of the software architecture and how it interrelates with the architecture of web browser. Having a working reference that could be used for the project will help both during maintenance and design time.

all other businesses so they try fitting as many customers on to one server as

Caching is a computer 's ability to store information that will help facilitate future access to a website. For example, if a user visited Facebook in the morning and decides to do so again in the evening, the computer will remember how it initially got access to Facebook and use it the second time. If the computer knows how to access a site, then it would have no need of going through the whole process, thus reducing internet traffic.

Since 1994, the REST architectural style has been used to guide the design and development of the architecture for the modern Web (Roy T. Fielding, 2000)

Page caching is the “back up” copy of a web page created by the search engines in order to improve the load time of web pages; these cached pages are served in place of most recent version.

In this way, mobile computing has brought some major changes to the internet world; some of them include cloud computing, social media services and e-commerce. Cloud computing is a service through which users can compute data, use applications and save their data online on internet. This stored data and applications can be accessed anywhere anytime. For example, if a user saves some data online in cloud from home desktop and then finds a need to access while being on a trip, it can be easily accessed through mobile phone or laptop just by connecting to internet. Similarly, applications can be used while being mobile.
