How do you configure hardware and software Essay Example for Free

How do you configure hardware and software Essay The most common colour depths are:   16 colours   256 colours   High Colour (16 bit, or 65,536 colours)   True Colour (24 bit, or over 16 million colours) Higher resolutions are greater number of colours require more memory. At 256 colours, each pixel requires one byte of memory. There are 8 bits in a byte, so each pixel in High Colour requires two bytes, and each pixel in True Colour requires three. Because of this, some video cards may restrict you to fewer colours in higher resolutions, due to the amount of memory required. For example, a True Colour display with a resolution of 1280 x 1024 pixels would require memory of 1280 x 1024 x 3 = 3,932,160 bytes, or nearly 4Mb! Drivers Different printers have different features, such as the ability to print in different fonts, and different resolutions (i. e. numbers of dots per inch) when printing graphics. Even where there are common features, such as the ability to print in bold, the codes that the computer needs to send to switch that feature on and off can vary from model to model. What the computer requires is some software called a driver, which can translate the codes generated by the program into codes suitable for the printer. In Windows, the drivers are installed centrally in the Control Panel so that each application, e. g. Excel or Word, can use the same drivers. In the days of DOS, each program often had its own printer driver. Other hardware devices, such as video cards, modems and scanners also require drivers. These perform the same function, allowing the computer to control the device. Sometimes the same driver can be used for similar devices (e.g. you may hear about Hayes compatible modems, or HP LaserJet compatible printers), but even in these cases it is often only by using the specific driver for that device that the most advanced features can be utilised. WYSIWYG and TrueType Fonts One of the problems with printing from a word processor or other application is that your text may not appear on paper as it did on the screen. With modern Graphical User Interfaces, this should be less of a problem, but with older character-based systems (such as DOS, or UNIX), fonts on the screen were not proportionally spaced. Characters could only appear at fixed intervals across the screen, and so it wasnt possible to insert fractions of spaces to justify the text. This meant that sometimes you could print out justified text, but not see what it was going to look like on the screen. A solution to this problem came with the arrival of WYSIWYG user interfaces. WYSIWYG stands for What You See Is What You Get, and means that your print should appear exactly as it does on the screen. Word (in Page Layout View, at least) is a WYSIWYG word processor; you get exactly what you see as you are typing. Other word processors, such as WordPerfect 5. 1 offer a halfway house solution, with a character-based input screen, and a graphical print preview. Even with GUIs and WYSIWYG word processors, there was still the problem of the fonts being used in the printer not being exactly the same as the ones used for display on the screen. This could lead to things not quite lining up, or not appearing as expected. A solution for this came with TrueType fonts. A TrueType font is used by Windows both for display on the screen and for printing. When you select a typeface in, say, Word, the TT symbol indicates a TrueType font. If you select one of these, you can be sure that your document will appear in the same way on paper as it did on the screen. Limitations of Hardware and Software Sometimes, due to the limitations of the hardware or software being used, a system will not be able to fully exploit the features of a peripheral. You will not be able to use certain fonts that a printer may support, for example, if the word processor you are using will not let you select that font, or if you are printing from, say, Notepad. Also, there is no point in you being able to scan things in 24-bit colour (i.e. 16 million colours) if your monitor cannot display that many, or you need to save the image as a GIF (GIFs only support 256 colours; if you want more colours than that, save your picture as a jpeg). Some modern printer drivers are applications in their own right, and have minimum hardware requirements specified. The drivers for my printer at home, for example, will not run on a 386. Examination Questions When installing or configuring a particular word processing package, the documentation states that the correct printer driver must also be installed. What is a printer driver, and why is it necessary? (1997) A company sells a range of health foods at five different shops. It also sells directly to the home from a number of vehicles. There are hundreds of different items of stock and many items are seasonal, so items in stock are constantly changing. Customers purchase goods and pay by cash, cheque or credit card. The company is considering a computerised system to help manage sales and stock control. Discuss the capabilities and limitations of current   communications devices,   input devices,   output devices and   storage devices.

The Island of Jamaica Essay -- Jamaica Countries Geography

The Island of Jamaica The island of Jamaica is the third largest Caribbean island. It is in a group of islands called the greater antilles. It has an area of 10 991 km squared or 4 244 sq. miles. Jamaica spans 230 km east to west and from 80-36 from north to south. It is third only to Cuba, which is the largest, and Hispaniola which is the second largest island. Jamaica lies in the Caribbean sea which is a part of the much larger Atlantic ocean. The island is 960 km south of Florida, 160 km southwest of Haiti, and 140 km south of Cuba. Jamaica is mainly a mountainous island but there are 320 km of fine sandy beaches, swamps, moist fern- forests, sprawling open plains, plateaus, rushing rivers, and magnificent waterfalls. The Blue Mountains are the highest mountains in Jamaica and Blue Mountain Peak which is the highest peak in Jamaica rises to 2256 m or 7 402 feet. They are made up primarily of limestone. Farther to the west in the cockpit country the limestone has eroded over many years to form large depressions, narrow valleys, underground caverns and rivers. Most of the surface rivers are short, swift flowing and descend quickly to the coast and consist of a series of rapids and waterfalls. The island is ringed by plains separated by mountain and sea. The country is divided into three counties. They are Cornwall to the west, Middlesex is central, and Surrey is to the east. Middlesex is the largest county. Jamaica is also divided into 14 parishes which are basically like provinces or states. The parishes are Kingston, St. Andrew, St. Thomas, Portland, St. Mary, St. Ann, Trelawny, St. James, Hanover, Westmoreland, St. Elizabeth, Manchester, Clarendon, and St. Catherine. .. ...

Identify the important skills/techniques Essay

Identify the important skills/techniques and fitness components needed for participation in this position/role and explain why they are important.  Badminton has many vital skills, techniques and fitness components needed for participation in a singles match. First of all being that you must have good hand eye coordination. Which would enable various parts of the body to combine in producing a desired movement or sequence of movements. This occurs as a result of interaction between the body’s movement and its nervous system. The ability to produce co-ordinated movement is essential for successful performance in sporting skills. For example in badminton you need each part of your body to move in a particular way at a specific time to hit the shuttle cock back successfully and efficiently to where you want it. (Drop shot, Smash shot etc) Also another factor needed is balance. In many sports and games, the concept of balance relates to our ability to keep our center of mass over our support. An example is of a badminton player as he/she must be able to move in any direction in order to return an opponent’s shot and must therefore be in a balanced position to do so. Another important factor is agility. Which involves the performer to move in a controlled way and to change direction, turn, stop and start quickly again. As in badminton you have to be ‘quick-footed’. Which is the ability to adjust the position of the body quickly and in the correct way that is valuable to all participants in physical activities. You need agility in badminton to be able to adjust your body from one position to another in order to hit the shuttlecock. Another crucial factor is the speed of reaction. In order to be good at singles badminton you must have a good reaction time. Which is the time it takes for example to get to a shuttlecock and hit it back. Also movement time is necessary a good one. Which is the time taken between the initiation of a response and the completion of the movement. So it’s like the time taken between the badminton player deciding on the right place to on the court and his/her starting to move (initiation of the response) and making the movement to the place on the court and hitting the shuttle cock. (Completion of the movement). Also a good reaction time is needed to be good at badminton. Which is the total time between the initial stimulus, the response to it and the completion of that response to that. Which is the time taken to react to the shuttlecock on your side of the court and hit it back to the opposing side before it touches the floor. Timing is also needed for badminton in a singles match. It is the right to hit the shuttlecock. If you hit it to late you may be open to a smash shot. Timing can be influenced by internal mechanisms e.g. knowing where the shuttle is going to land. Timing is also knowing and responding to a game.  These are all equipment and court size the badminton court must be in order to be passed by the England badminton officials. Court size for singles – 44 feet long x 17 feet wide Shuttlecocks – Also known as birdies or birds. One type has feathers with a cork base, and the other is plastic with a rubber base. Rackets – Made of lightweight material like wood, plastic or metal. Court size for doubles – 44 feet long x 20 feet wide. Net height – 5 feet. The object of the badminton is to hit the shuttlecock back and forth over a net without permitting it to hit the floor in bounds on your side of the net.  Here are some general rules and terms for badminton:  1. A player may not touch the net with a racket or history body during play.  2. A shuttlecock may not come to rest or be carried on the racket.  3. A shuttlecock may hit the net on its way across during play and the rally can continue.  4. A term of service is called an inning.  5. A player may not reach over the net to hit the shuttlecock. 6. A loss of serve is called a side out.  7. In class games will be played to 15 points and a match is 2 out of 3 games.  8. Some types of shots are the lob, drop shot, smash and drive.  Here are some rules of serving in badminton:  1. A coin toss or spin of the racket determines who will serve first.  2. The serve must travel diagonally (cross court) to be good.  3. A serve that touches the net and lands in the proper court is called a let serve and is reserved, otherwise, only one serve is permitted to each court until a side out occurs. A serve that is totally missed may be tried again. 4. The racket must make contact with the birdie below the waist on a serve.  5. The server and receiver shall stand within their respective service courts until the serve is made  Section 2: Identify and describe in detail the strength of the player/participant and the effects these have on performance.   I am particularly good at doubles matches. My strengths are that I have good hand eye coordination so I can predict where the opponent is going to hit the shuttlecock back at my side of the court. The ectomorph is the best build in order to play badminton, which I am closest to out the 3 builds. I also have good agility so I can move in a controlled way to change direction, turn, stop and start again quickly. I can be seen as quick footed. Meaning I can move my whole body with freedom an with ease. I perform the important skills such as drop shot (forehand), overhand clear (forehand) and smash (forehand) and also net shots (forehand and backhand) to a reasonablely good standard. I am good with supporting other performers, in a doubles match, as I know the footwork in order to help the other performer. E.g. if the opponent in a doubles match hits the shuttlecock to the back of the court an my partner hits it I would be at the front making sure no drop shots would be able to win them there point. So I see myself as more of a defensive player making sure I am always in the opposite place to my partner. E.g. if he’s at the front I would be at the back and vice versa. I move well around the court in order to hit the shuttlecock back to my opponent as I am ‘ light footed’ and as I am agile. My body position for when I hit the shuttlecock is accurate as when it is hit I rotate my hips a bit. My timing for hitting the shuttlecock is good as most of the time I hit the shuttlecock an do not miss it. I am mostly consistent at hitting the shuttlecock back. In order to play the game well you must have appropriate fitness levels for stamina and speed. In order to get to the shuttlecock quickly and constantly without getting tired. Section3: Identify and describe in detail the weakness of the player/participant and the affects these have on performance.  I show some weakness in attacking in badminton when smashing the shuttlecock to the opponent to the back of the court it sometimes goes out of bounds. I show a limited amount of tactical awareness. As I am aware for where to go as the opponent hits the shuttlecock back. But don’t always go to where is needed in order to hit the shuttlecock back in a way that the opponent can’t smash it. The movement around the court is fine not clumsy or slow but may sometimes not be fast enough. I am sure that my footwork is fine as well as my arm action as hitting the shuttlecock and my body position is fine in order to hit the shuttlecock. I only play with my right hand as I am not as coordinated with my left hand and may miss the shuttlecock. My timing for when to hit the shuttlecock is good as I most of the time manage to hit it. My work rate in order to play badminton is ok, as effort is low. The fit components of mine including stamina and speed are reasonablely good.

The Most Important Fuel Of The World Is Energy Essay

The most important fuel in the world is energy. Energy is the capability to do work or the power which can make changes in matter. We can use it in different ways in everyday life such as transportation, entertainment, communication, personal comfort, agriculture and manufacturing. The world will come to a standstill without energy. The best thing about energy is it can neither be created nor be destroyed it just changes from one form of matter into another form.1 We can obtain energy in a useful form by a system called Energy Harnessing Network. In this complicated system we extract raw energy in the form of heat energy, light energy, solar energy etc and then transformed it into fuel for example coal, natural gas, petroleum and electrical energy then stored it and use when needed. The engineers did a lot of work on it and successfully did what was think impossible in the earlier time. They harnessed energy in many different forms such as hydropower, solar power, wind mills and nucl ear power etc. There are two main types of energy that is kinetic energy and potential energy. If the object is at rest then the energy it possess is called potential energy and if the object is in motion then it possess kinetic energy. A well-known scientist called Gottfried Wilhelm Leibniz, formulated another theory of movement (flow) in view of kinetic energy and potential energy, which placed space as relative, though Newton was altogether persuaded that space was outright.
