==**Blog** (a contraction of the term weblog) is a website, usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog.==

Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (artlog), photographs (photoblog), sketches (sketchblog), videos (vlog), music (MP3 blog), audio (podcasting), which are part of a wider network of social media. Micro-blogging is another type of blogging, one which consists of blogs with very short posts. As of December 2007, blog search engine Technorati was tracking more than 112 million blogs.[1] With the advent of video blogging, the word blog has taken on an even looser meaning — that of any bit of media wherein the subject expresses his opinion or simply talks about something.

Storage capacities typically range from 64 MB to 64 GB[|[][|2][|]] with steady improvements in size and price per [|gigabyte]. Some allow 1 million write or erase cycles[|[][|3][|]][|[][|4][|]] and have 10-year data retention,[|[][|5][|]] connected by [|USB 1.1] or [|USB 2.0]. (taken from wikipedia)

COOKIES:
HTTP cookies, more commonly referred to as Web cookies, tracking cookies or just cookies, are parcels of text sent by a server to a Web client (usually a browser) and then sent back unchanged by the client each time it accesses that server. HTTP cookies are used for authenticating, session tracking (state maintenance), and maintaining specific information about users, such as site preferences or the contents of their electronic shopping carts. The term "cookie" is derived from "magic cookie," a well-known concept in UNIX computing which inspired both the idea and the name of HTTP cookies. Tracking cookies track your web browsing habits. They can collect information about pages and advertisements you have seen or any other activity during browsing. Different websites can share tracking cookies, and each website with the same tracking cookie can read the information and write new information into it.

Because they can be used for tracking browsing behavior, cookies have been of concern for Internet privacy. As a result, they have been subject to legislation in various countries such as the United States, as well as the European Union. Cookies have also been criticized because the identification of users they provide is not always accurate and because they could potentially be a target of network attackers. Some alternatives to cookies exist, but each has its own uses, advantages, and drawbacks.

Cookies are also subject to a number of misconceptions, mostly based on the erroneous notion that they are computer programs that run on the browsing computer. In fact, cookies are simple pieces of data that affect the operation of a web server, not the client, and do so in very specific ways. In particular, they are neither spyware nor viruses, although cookies from certain sites are described as spyware by many anti-spyware products because they allow users to be tracked when they visit various sites.

Most modern browsers allow users to decide whether to accept cookies, but rejection makes some websites unusable. For example, shopping carts implemented using cookies do not work if cookies are rejected.



CACHE:
In computer science, a cache (pronounced /kæʃ/) is a collection of data duplicating original values stored elsewhere or computed earlier, where the original data is expensive to fetch (owing to longer access time) or to compute, compared to the cost of reading the cache. In other words, a cache is a temporary storage area where frequently accessed data can be stored for rapid access. Once the data is stored in the cache, future use can be made by accessing the cached copy rather than re-fetching or recomputing the original data, so that the average access time is shorter.

A cache has proven to be extremely effective in many areas of computing because access patterns in typical computer applications have locality of reference. There are several kinds of locality, but this article primarily deals with data that are accessed close together in time (temporal locality). The data might or might not be located physically close to each other (spatial locality).
