Dairy Product

Dairy product is used by the people about thousands years ago. Though it seems normal to use the dairy products but through the use of it people are suffering from Crohn's Disease. Dairy product is not considered as a natural product for the human diet, as it indigested by our body.


The digestive system and physiology of the human are still same as it was earlier before 100,000 years ago. Through which we can say that we can digest the diet that is rich in fruit, food and vegetables which was mostly unrefined and unprocessed and this does not contain dairy product. Humans are the only one animal that had the milk throughout their adult life. Cow is a mammal who feed the milk to their younger ones for certain period of time and will begin to eat grass as their diet. Consuming the dairy product may not have any ill effect but it is always having side affect in the human body.

Through the high dairy consumption people are having the problems related to their bones such as osteoporosis. Some countries in which people have low dairy consumption are not having the problems related to bone especially at the old age. So, dairy is not considered as a natural food for the human body. Consuming a lot of dairy product act as alcohol in the bone of our body. It will also take all the alkaline minerals from the bone and other places of the body to equal the amount the acid formed from the affect of the dairy product. Though the truth is known by the dairy industry but pretend as they don’t know anything in order to run their business. In order to neutralize the acid of the body and protect the body it gives burden to the body. If the use of the dairy will have allergy but still continue to use it then Crohn’s disease symptoms get worse and any natural affect like medicine would be effective less.

In conclusion through the use of the dairy products Crohn’s diseases get more diet. Through which natural approaches may succeed or fail in order to recover the diseases. One of the most essential things that should be done in order to maintain health is to eliminate the use of the diary product and have the diet like food, fruit and vegetables. Hence, dairy is not considered as a natural product and diet food.

Uses of Output Devices

Monitor 

A monitor is the screen on which words, numbers, and graphics can be seem.  The monitor is the most common output device.

Compact Disk 

Some compact disks can be used to put information on.  This is called burning information to a CD.
NOTE:  A CD can also be an input device.

Printer

A printer prints whatever is on the monitor onto paper.  Printers can print words, numbers, or pictures.

Speaker 

A speaker gives you sound output from your computer.  Some speakers are built into the computer and some are separate.  

Disk Drives 

A disk drive is used to record information from the computer onto a floppy disk or CD.

Floppy Disk 

A floppy disk is used to record information on.  The information is stored on the floppy disk and can be used later or used on another computer.

Headphones 

Headphones give sound output from the computer.  They are similar to speakers, except they are worn on the ears so only one person can hear the output at a time.   

Use of in put devices

 These are some of the uses of input devices:
Keyboard
The Keyboard is the standard data input and operator control device for a computer.It consists of the standard QWERTY layout with a numeric keypad and additional function keys for control purposes.
Mouse 
The Mouse is a popular input device. You move it across the desk and its movement is shown on the screen by a marker known as a 'cursor'. You will need to click the buttons at the top of the mouse to select an option. 
Joystick
The joystick is a rotary lever. Similar to an aircraft's control stick, it enables you to move within the screen's environment, and is widely used in the computer games industry. 
The Optical Mark Reader (OMR) 

The Optical Mark Reader (OMR) can read information in the form of numbers or letters and put it into the computer. The marks have to be precisely located as in multiple choice test papers.
Light Pen
A Light Pen is a pointing device shaped like a pen and is connected to a VDU.
The tip of the light pen contains a light-sensitive element which, when placed against the screen, detects the light from the screen enabling the computer to identify the location of the pen on the screen.Light pens have the advantage of 'drawing' directly onto the screen, but this can become uncomfortable, and they are not as accurate as digitizing tablets. 
Sound Capture
With the addition of a sound card in one of the expansion slots of your computer you can "record" voice or music. The sound card digitizes the information into a form that the computer can understand.
Video Capture
With a video capture board in one of your computer's expansion slots you can capture video (photographic) images through a video camera.
The video capture board digitizes the image.

 

Disadvantages of Using Computer System

Disadvantages may include greater complexity of life - everyone now has to learn a lot of skills even to use computers at a simple level. They also generate a lot of extra work such as answering emails, and producing high quality documents for all occasions (before, you might just scribble something down.) Some people think we are becoming deskilled - forgetting how to do simple things like mental arithmetic, and also the availability of so much knowledge doesn't necessarily mean that we, individually, know more. It's easy to think that you have nderstood a topic, just because you can download a fact sheet about it.

Advantages of using computer

 The potential advantages for using a computer depend closely on the intended use. Given a few potential uses, here are some of my thoughts:

For writing:

• Quick entry
• Easy to edit and restructure

For organization

• Once a document is in electronic form it is easy to store and many, many documents can be stored on one computer in much less space than in a file cabinet.
• Easy to search

For programming

• Most programming requires the use of computers
• Using a computer makes it easy to search code and tools make it easier to understand it
• Easily gather programs from other creators
• Easily distribute your own works

For research

• Access to the Internet has become invaluable as a research tool
• Easily gather huge amounts of information and store it.
• Easily search for new information or search the information already acquired
• Interact with other researchers to create/gather more research
• Almost instant access to many remote or obscure locations of the globe and their researchers/experiences/knowledge
• Easily disseminate results of your own research

Purpose of using computer networks

Computer networks can be used for several purposes:

• Facilitating communications. Using a network, people can communicate efficiently and easily via e-mail, instant messaging, chat rooms, telephone, video telephone calls, and video conferencing.
• Sharing hardware. In a networked environment, each computer on a network can access and use hardware on the network. Suppose several personal computers on a network each require the use of a laser printer. If the personal computers and a laser printer are connected to a network, each user can then access the laser printer on the network, as they need it.
• Sharing files, data, and information. In a network environment, any authorized user can access data and information stored on other computers on the network. The capability of providing access to data and information on shared storage devices is an important feature of many networks.
• Sharing software. Users connected to a network can access application programs on the network.

Use of keyboard

Use of keyboard

ENTER or RETURN - Moves the cursor down one line and to the left margin. Enter also process commands such as choosing an option in a dialog (message) boxes and submitting a form.

DEL or DELETE - Deletes the character at cursor and/or characters to the right of the cursor and all highlighted (or selected) text.

BKSP or BACKSPACE - Deletes the character to the left of cursor and all hightlighted text.

SPACE BAR - Moves the cursor one space at a time to the right

SHIFT KEY - Use the shift keys to type capital letters and to type the upper character on keys with two characters on them

CAPS LOCK - Locks the keyboard so it types capital letters (a light goes on when caps lock is on)

TAB - Moves the cursor five spaces to the right (number of spaces are usually adjustable). Tab moves to the next field in a form or table (Shift-Tab for previous field).

ESC or ESCAPE - Cancels a menu or dialog box

ARROW KEYS - Moves the cursor around document without changing text

Function of the computer

Computer can be functioned with three steps which can be categorised as input, output and processing system. The function of the computer is used in order to input, output, store and process the data or information in the computer system.
Input system refers to the communication between an information processing system (such as a computer), and the outside world possibly a human, or another information processing system. Input system is used in order to input the information in the computer. Information can be stored in the computer with the help of the hardware like keyboard, mouse, scanner, drives and so on.
Output system is used in order to display the information from the computer.Information can be displayed from the computer with the help of the hardware like monitors, printers and so on.
Processing system is used in order to process the information in the computer in order to display the information or data from the computer or to store the data or information in the computer for the further use.

Introduction

A computer is a programmable machine that input, stores and manipulates data or information, and provides output in a useful format. Input, output and processing are the three functions of the computer. There are two basic types of computer. They are classified into hardware and software.
The hardware are the parts of computer itself including the Central Processing Unit (CPU) and related microchips and micro-circuitry, keyboards, monitors, case and drives (hard, CD, DVD, floppy, optical, tape, etc...). Other extra parts called peripheral components or devices include mouse, printers, modems, scanners, digital cameras and cards (sound, colour, video) and so on. Together they are often referred to as a personal computer.
The software is the information that the computer uses to get the job done. Software needs to be accessed before it can be used. There are many terms used for process of accessing software including running, executing, starting up, opening, and so on.
