Module 3

A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations.
The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem. Conventionally a computer consists of some form of memory for data storage, at least one element that carries out arithmetic and logic operations, and a sequencing and control element that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from external source, and allow the results of operations to be sent out.

A computer's processing unit executes series of instructions that make it read, manipulate and then store data. Conditional instructions change the sequence of instructions as a function of the current state of the machine or its environment

A pencil is a writing implement or art medium usually constructed of a narrow, solid pigment core inside a protective casing. The case prevents the core from breaking, and also from marking the user’s hand during use.

Pencils create marks via physical abrasion, leaving behind a trail of solid core material that adheres to a sheet of paper or other surface. They are noticeably distinct from pens, which dispense liquid or gel ink that stain the light color of the paper.

Most pencil cores are made of graphite mixed with a clay binder, leaving grey or black marks that can be easily erased. Graphite pencils are used for both writing and drawing, and the result is durable: although writing can usually be removed with an eraser, it is resistant to moisture, most chemicals, ultraviolet radiation and natural ageing. Other types of pencil core are less widely used.Charcoal pencils are mainly used by artists for drawing and sketching. Colored pencils are sometimes used by teachers or editors to correct submitted texts but are more usually regarded as art supplies, especially those with waxy core binders that tend to smear on paper instead of erasing. Grease pencils have a softer crayon-like waxy core that can leave marks on smooth surfaces such as glass or porcelain.

The most common type of pencil casing is a thin wooden cylinder permanently bonded around the core. Similar permanent casings may be constructed of other materials such as plastic or paper. In order to use the pencil, the casing must be carved or peeled off to expose the working end of the core as a sharp point. Mechanical pencils have more elaborate casings that support mobile pieces of pigment core, which can be extended or retracted through the casing tip as needed.

Paris is one of the most well known cities and one of the most popular tourist destinations in the entire world. Paris is a busy city with a reasonably large population of around ten million with over two million residing in the centre. The number of people that live in Paris means it is a well traveled city.

Paris has the unique pleasure of being the international capital of fashion and art and when fashions are launched, it is normally from this city. This is also a city know for its associated with art and world famous artists with galleries and museums to please even the most discerning of visitors.

If you are planning a trip to Paris there are three landmarks that you must save time for but there are of course many more attractions than just those three, but these are the big ones. The three I refer to are The Arch de Triomphe, the Eiffel Tower and Notre Dame Theater which cannot be missed even if they each have many hundreds of thousands of visitors each year.

The Louvre internationally renowned museum is in Paris and has enough exhibits to keep even the most demanding person occupied for days with many hundreds of visitors every day. The number of exhibits is huge but the most famous is the painting The Mona Lisa and while it should not be missed, there are many other reasons to spend time there.

As far as the weather is concerned, most tourists are lucky and can visit at any time of the year without too many worries about any form of extreme weather. During the winter months of December and January temperatures may fall into the upper 30′s to the lower 40′s and in the summer months, July and August in particular, 75 degrees Fahrenheit is the average temperature so this makes for easy travel in Paris regardless of what time of the year it is.

Of the two airports Paris has, it is Roissy-en-France which is the most popular and one of the most frequently used on the European continent while the second airport, Orly, only has a fraction of the air traffic. The great benefit of using Roissy-en-France is that has connections to every major international airport around the world.

Paris has always been and will continue to be a popular destination for the lovers of art, fashion, food and culture as well as those who just go to relax. If you want to plan a trip to a great destination Paris is one option that you should consider as it has a lot to offer no matter what your interests are.

When you’re in Paris, then why not visit Amsterdam also. By plain you can get there in 2 hours. In case you stay for several days, make sure you first check some Amsterdam apartments online. When that is arranged, you can enjoy your stay without worrying about this
