Writing reports
Study guide
This guide has been written to provide a general introduction to writing reports. It outlines the typical structure of a report and provides a step by step guide to producing reports that are clear and well structured.
What is a report?
A report is written for a clear purpose and to a particular audience. Specific information and evidence are presented, analysed and applied to a particular problem or issue. The information is presented in a clearly structured format making use of sections and headings so that the information is easy to locate and follow. 
When you are asked to write a report you will usually be given a report brief which provides you with instructions and guidelines. The report brief may outline the purpose, audience and problem or issue that your report must address, together with any specific requirements for format or structure. This guide offers a general introduction to report writing; be sure also to take account of specific instructions provided by your department. 
What makes a good report?
Two of the reasons why reports are used as forms of written assessment are:
·         to find out what you have learned from your reading, research or experience;
·         to give you experience of an important skill that is widely used in the work place. 
An effective report presents and analyses facts and evidence that are relevant to the specific problem or issue of the report brief. All sources used should be acknowledged and referenced throughout, in accordance with the preferred method of your department. For further information see the Learning Development guide: Avoiding Plagiarism. The style of writing in a report is usually less discursive than in an essay, with a more direct and economic use of language. A well written report will demonstrate your ability to: 
·         understand the purpose of the report brief and adhere to its specifications;
·         gather, evaluate and analyse relevant information;
·         structure material in a logical and coherent order;
·         present your report in a consistent manner according to the instructions of the report brief;
·         make appropriate conclusions that are supported by the evidence and analysis of the report;
·         make thoughtful and practical recommendations where required. 

The structure of a report

The main features of a report are described below to provide a general guide. These should be used in conjunction with the instructions or guidelines provided by your department.

Terms of Reference

Under this heading you could include a brief explanation of who will read the report (audience) why it was written (purpose) and how it was written (methods). It may be in the form of a subtitle or a single paragraph.
A report submitted in fulfilment of the requirements for Course GL456, Department of Geology, Univeristy of Leicester.
Example of terms of reference

Summary (Abstract)

The summary should briefly describe the content of the report. It should cover the aims of the report, what was found and what, if any, action is called for. Aim for about 1/2 a page in length and avoid detail or discussion; just outline the main points. Remember that the summary is the first thing that is read. It should provide the reader with a clear, helpful overview of the content of the report.
Exposure of rocks belonging to the Charnian Supergroup (late Precambrian) were examined in the area around Beacon Hill, north Leicestershire. This report aims to provide details of the stratigraphy at three sites - Copt Oak, Mount St. Bernard Abbey and Oaks in Charnwood. It was observed that at each of these sites, the Charnian Supergroup consists mainly of volcaniclastic sediments (air-fall and ash-flow tuffs) interbedded with mudstones and siltstones. These rocks show features that are characteristic of deposition in shallow water on the flanks of a volcano (e.g. welding and alteration of ignimbrites). Further studies are required to understand depositional mechanisms and to evaluate the present-day thickness of individual rock units.
Example of a summary (abstract)

Contents (Table of Contents)

The contents page should list the different chapters and/or headings together with the page numbers. Your contents page should be presented in such a way that the reader can quickly scan the list of headings and locate a particular part of the report. You may want to number chapter headings and subheadings in addition to providing page references. Whatever numbering system you use, be sure that it is clear and consistent throughout.
Introduction
The introduction sets the scene for the main body of the report. The aims and objectives of the report should be explained in detail. Any problems or limitations in the scope of the report should be identified, and a description of research methods, the parameters of the research and any necessary background history should be included. 
In some reports, particularly in science subjects, separate headings for Methods and Results are used prior to the main body (Discussion) of the report as described below. 

Methods

Information under this heading may include: a list of equipment used; explanations of procedures followed; relevant information on materials used, including sources of materials and details of any necessary preparation; reference to any problems encountered and subsequent changes in procedure. 

Results

This section should include a summary of the results of the investigation or experiment together with any necessary diagrams, graphs or tables of gathered data that support your results. Present your results in a logical order without comment. Discussion of your results should take place in the main body (Discussion) of the report. 

Discussion

The main body of the report is where you discuss your material. The facts and evidence you have gathered should be analysed and discussed with specific reference to the problem or issue. If your discussion section is lengthy you might divide it into section headings. Your points should be grouped and arranged in an order that is logical and easy to follow. Use headings and subheadings to create a clear structure for your material. Use bullet points to present a series of points in an easy-to-follow list. As with the whole report, all sources used should be acknowledged and correctly referenced. For further guidance check your departmental handbook and the Student Learning Centre guide: Referencing and Bibliographies. 

Conclusion 

In the conclusion you should show the overall significance of what has been covered. You may want to remind the reader of the most important points that have been made in the report or highlight what you consider to be the most central issues or findings. However, no new material should be introduced in the conclusion. 

Appendices

Under this heading you should include all the supporting information you have used that is not published. This might include tables, graphs, questionnaires, surveys or transcripts. Refer to the appendices in the body of your report.
In order to assess the popularity of this change, a questionnaire (Appendix 2) was distributed to 60 employees. The results (Appendix 3) suggest the change is well received by the majority of employees.
Example of use of appendices

Bibliography

Your bibliography should list, in alphabetical order by author, all published sources referred to in your report. There are different styles of using references and bibliographies. Refer to the study guide Referencing and Bibliographies and check your departmental handbook for guidelines. Texts which you consulted but did not refer to directly could be grouped under a separate heading such as 'Background Reading' and listed in alphabetical order using the same format as in your bibliography. 

Acknowledgements

Where appropriate you may wish to acknowledge the assistance of particular organisations or individuals who provided information, advice or help. 

Glossary of Technical Terms

It is useful to provide an alphabetical list of technical terms with a brief, clear description of each term. You can also include in this section explanations of the acronyms, abbreviations or standard units used in your report. 
You will not necessarily be required to use all of the headings described above, nor will they necessarily be in the order given here. Check your departmental guidelines or instructions. 

Writing the report: the essential stages

All reports need to be clear, concise and well structured. The key to writing an effective report is to allocate time for planning and preparation. With careful planning, the writing of a report will be made much easier. The essential stages of successful report writing are described below. Consider how long each stage is likely to take and divide the time before the deadline between the different stages. Be sure to leave time for final proof reading and checking. 

Stage One: Understanding the report brief

This first stage is the most important. You need to be confident that you understand the purpose of your report as described in your report brief or instructions. Consider who the report is for and why it is being written. Check that you understand all the instructions or requirements, and ask your tutor if anything is unclear. 

Stage Two: Gathering and selecting information

Once you are clear about the purpose of your report, you need to begin to gather relevant information. Your information may come from a variety of sources, but how much information you will need will depend on how much detail is required in the report. You may want to begin by reading relevant literature to widen your understanding of the topic or issue before you go on to look at other forms of information such as questionnaires, surveys etc. As you read and gather information you need to assess its relevance to your report and select accordingly. Keep referring to your report brief to help you decide what is relevant information. 

Stage Three: Organising your material

Once you have gathered information you need to decide what will be included and in what sequence it should be presented. Begin by grouping together points that are related. These may form sections or chapters. Remember to keep referring to the report brief and be prepared to cut any information that is not directly relevant to the report. Choose an order for your material that is logical and easy to follow. 

Stage Four: Analysing your material

Before you begin to write your first draft of the report, take time to consider and make notes on the points you will make using the facts and evidence you have gathered. What conclusions can be drawn from the material? What are the limitations or flaws in the evidence? Do certain pieces of evidence conflict with one another? It is not enough to simply present the information you have gathered; you must relate it to the problem or issue described in the report brief. 

Stage Five: Writing the report

Having organised your material into appropriate sections and headings you can begin to write the first draft of your report. You may find it easier to write the summary and contents page at the end when you know exactly what will be included. Aim for a writing style that is direct and precise. Avoid waffle and make your points clearly and concisely. Chapters, sections and even individual paragraphs should be written with a clear structure. The structure described below can be adapted and applied to chapters, sections and even paragraphs.
·         Introduce the main idea of the chapter/section/paragraph
·         Explain and expand the idea, defining any key terms.
·         Present relevant evidence to support your point(s).
·         Comment on each piece of evidence showing how it relates to your point(s).
·         Conclude your chapter/section/paragraph by either showing its
significance to the report as a whole or making a link to the next chapter/section/paragraph.

Stage Six: Reviewing and redrafting

Ideally, you should leave time to take a break before you review your first draft. Be prepared to rearrange or rewrite sections in the light of your review. Try to read the draft from the perspective of the reader. Is it easy to follow with a clear structure that makes sense? Are the points concisely but clearly explained and supported by relevant evidence? Writing on a word processor makes it easier to rewrite and rearrange sections or paragraphs in your first draft. If you write your first draft by hand, try writing each section on a separate piece of paper to make redrafting easier. 

Stage Seven: Presentation

Once you are satisfied with the content and structure of your redrafted report, you can turn your attention to the presentation. Check that the wording of each chapter/section/subheading is clear and accurate. Check that you have adhered to the instructions in your report brief regarding format and presentation. Check for consistency in numbering of chapters, sections and appendices. Make sure that all your sources are acknowledged and correctly referenced. You will need to proof read your report for errors of spelling or grammar. If time allows, proof read more than once. Errors in presentation or expression create a poor impression and can make the report difficult to read. 

Feedback

Any feedback from tutors on returned work can be used to create a checklist of key points to consider for your next report. Identify priority areas for attention and seek out further information and advice. Speak to your tutor or an adviser from the Learning Development. Used in this way, feedback from tutors can provide a useful tool for developing and improving your writing skills.

The big idea
   Whenever you're asked to decide whether something is good or bad--and then explain why on paper--you're being asked to write a *review* or *evaluation*.  This is a valuable style of writing to learn, because even if you don't wind up writing book reviews for a living, you will still need to make big decisions as an adult about which car or house to buy, or which college to attend.  The kind of thinking you need to use in writing reviews is the kind of thinking you need to make intelligent choices in life.
Before you begin
   Step One: Decide What To Look At
The first thing you need to do before you start your review is decide what aspects of the item you are going to evaluate.  What I mean is this: what is it that can be good or bad about something you're going to review?  An example: when you're watching a movie, you can look at the acting, the special effects, the camera work, or the story, among other things.  Those are all items you can examine and decide if they are well or poorly done.  With a book, you can look at the plot, the characters, and the way that the author puts words together.  With a restaurant, you can look at the food, the service, and the setting.  In fact, everything has qualities you can analyze and evaluate; you just need to sit down and figure out what they are.
   Step Two: Decide What Makes Things Good or Bad
Before you can decide whether something is good or bad, you have to figure out what you mean by "good" and "bad." Do you like stories that have a lot of action or a lot of character development?  Do you like acting that's realistic or acting that's wild and nutty?  Do you like authors to use a lot of complicated words, or very simple words?  You decide.  Whatever you like, apply those standards to the thing you are reviewing.
How to do it
It is now time to start putting your essay together.  Here's a pretty simple format you can follow:
1.      Open with an introduction paragraph that does the following things:
Ø  catches the reader's attention;
Ø  identifies the thing you'll be reviewing (e.g., the title of the book or movie);
Ø  identifies the author, star, or director, if appropriate.
2.      Write a full paragraph about each of the aspects you want to examine, making sure each paragraph does these things:
Ø  opens with a topic sentence that says what the paragraph is about;
Ø  has several detail sentences that prove the point you are trying to make;
Ø  uses quotes or examples from the book or movie, if possible, to help prove your point.
3.      End with a conclusion paragraph that does the following:
Ø  *briefly* restates the main ideas of the review;
Ø  makes a judgment about the book or movie or whatever, saying whether it is good or bad (some reviewers give ratings, like four stars or two thumbs up);
Ø  recommends that the reader go to the movie or read the book or buy a meal at the restaurant (or not, if it is no good).
An example
Losing Joe's Place
by Gordon Korman
book review by Mr.  Klingensmith
   It's not often that one finds a novel as wacky and as full of unexpected surprises as Losing Joe's Place, a book by Gordon Korman.  It is the story of Jason Cardone and his friends Ferguson "The Peach" Peach and Don "Mr.  Wonderful" Champion, and a summer they spend in the big city of Toronto, subletting the totally cool bachelor apartment that belongs to Jason's brother, Joe.  Joe's instructions to the three teenagers boil down to one main thing: DON'T GET EVICTED!  The story shows us just how hard it can be to follow this one simple direction.
   One great thing about the book is the way Korman developed the characters.  Each person has a definite personality.  The Peach is an engineering genius who needs to improve everything he sees.  His "better than you are" attitude tends to get on everyone's nerves.  Jason, our hero, seems to be allergic to work, and while his roommates spend the summer slaving away at a variety of jobs, Jason finds ways to avoid job interviews.  At the same time, he becomes a genius in the kitchen, which helps him later on in the story.  Mr.  Plotnick, the boys' landlord and owner of the Olympiad Delicatessen, is one of the greediest and most annoying people you'll ever meet in a book, and the boys spend a lot of their time trying to find ways to get even with him.  Perhaps one of the weirdest characters in the book is Rootbeer Racinette, a huge bearded giant who can chew a hole in an unpoppable truck tire and take a two-by-four in the stomach as hard as you'd care to swing it.  Rootbeer spends the summer with the boys, taking turns getting the boys into and out of trouble (between bouts of Manchurian Bush Meditation and pursuing some of the strangest hobbies in the world).
   Another great thing about the book is the plot.  Just as it seems that the boys are going to finally solve their problems and have a great summer, another problem arises that they have to solve, or else they will have to go back home to Owen Sound as the total failures that their parents expect: they run out of money more than once; they fight over the love of a girl they meet in Toronto, and they wind up becoming the secret restaurant kings of the city, all because of a chocolate memory.  Whenever you think that things can't get worse, they can, and the whole book builds toward the finish that you hoped couldn't happen...

   Losing Joe's Place is a great book for anyone who likes to see somebody else have a whole lot of funny, funny troubles.  The story is hilarious and keeps you on the edge of your seat, and the characters are strange and interesting enough to make you want to know more about what will happen to them next.  Out of four stars, I would give this book at least three and a half.

                                                     ICT in my future life 
Over the last few years, information technology's impact on society has become a hot topic. It is clear that in the coming decades information and communication technologies (ICT or IT) will affect and reshape most parts of our society.
It will come to radically influence the global economy, and, to an unknown degree, our culture and the way we perceive the world, our relationship to it, and our actions.
  Although ICT will have an enormous effect on tomorrow's society, surprisingly little research has been conducted regarding its future environmental consequences. Most of the work that has been done has reached one of two opposing conclusions: either ICT will bring only good things, from solutions to world hunger, the elimination of all transportation problems and a revitalised democracy.
  Or it will bring nothing but problems, accelerating resource consumption, introducing new toxic materials and resulting in greater inequity by introducing a digital divide that will worsen the already unequal distribution of wealth and influence.
Go beyond these polarised perspectives
The first challenge, if we want to tackle the challenges surrounding ICT for the future, is to go beyond these polarised perspectives.
   ICT is a tool that constitutes a new infrastructure, changing the way our societies function, while its technical applications will give us totally new opportunities to both preserve the best elements of our society, and develop new and better solutions to our existing problems.
   As a whole, ICT is best viewed as a catalyst that can speed up current negative trends, or alternatively contribute to a shift towards sustainable development.
No one knows specifically what role it will play in the future, but we know that it will be significant and that our decisions today will influence the direction in which it will develop tomorrow.

Networking
   Networking is the word people use when they're talking about connecting computers together so they can share data with each other and all connect to the internet at the same time. Let's take a closer look at the key components that make up a simple easy to set up network. Think of a network is something similar to your body central nervous system. At the top of the network is a brain that handles all the traffic coming through. This is called a router.
    The brain is connected to a spine that send signals throughout your network. This device is called a switch and it distributes signals to all of your computers and devices via network cables. Now let's check out each of the components of a wired network and more detail.
   We'll start with the router. A router has a smart little computer inside that identifies all of the computers and devices on your network and assigns a unique number to each one.
   Techie people call this an IP address. A router also connects to the internet outside your home via a modem that can be provided by your dsl or cable internet provider. A router is always at work. Managing the tons and tons of information your computers and devices send and receive and controlling which computers and devices get what information and when so how does a router actually send information from the internet to your computers and devices and how does it enable your computers to share information with each other.
   The answer lies with that device we mentioned earlier a switch. A switch sins traffic through your network to the places it needs to go. Every netgear home router has a switch with four ports built right into it you can also get wireless routers from netgear that use radio signals to do. The same thing as a switch but these still have those four ports built into them so you can use wires. With them too when you're buying a router for use in a wired.
   Network pay attention to the speed of the built-in switch the fastest switches are called gigabit and they're perfect for applications like streaming video in your home meanwhile routers switches called fast ethernet are great for essential tasks like web surfing email and online gaming now say you have more than four idea as you'd like to plug into. A router you need more ports the solution is easy you'll need an additional switch which again is that thing that's already built into your router in this case though you just need to switch portion and not another router. Because your network doesn't need two brains after all netgear has switches with as few as five ports as well as some that feature ports or more once again.

    If you need the fastest speeds go for a gigabit switch your smarty pants net gear router will recognize. These new connections and start sending data to them right away here's one more thing to keep in mind some people often confuse a switch with a related device called a hub. Which is obsolete you just need to know that hubs were replaced by switches. Because switches do the same thing but with a lot more speed and smarts a router a switch and network cables all come together to create a fast and reliable wired network. That works a lot like your body's nervous system fortunately you don't have to be super brainy to understand how it all works.
Техник хангамж
Компьютерийг бүрдүүлэгч техник хангамжийн функцыг ерөнхийд нь дараах 5н ангилалд хуваадаг. Оролт, санах ой, үйлдэл, удирдлага болон гаралт.
Дараах зүйлүүд бол хэсгүүд юм. Энэ хэсгүүд нь функцыг хэрэгжүүлдэг хэсгүүд юм.
Оролтын хэсэг: Энэ хэсэг нь компьютерийн үйл ажиллагаанд зориулж өгөгдлүүд ба программыг оруулдаг. Энэ нь хүний нүд болон чихтэй адил.
Санах ой: Оролтын өгөгдөл буюу программыг хадгалдаг. Энэ нь санах ойн хэсэг бөгөөд хүний тархины хэсэгтэй ижил.
Үйлдлийн хэсэг: Программын команд нь өгөгдлийн тохиргоог хадгалах, шийдийг олох болон тооцоолол хийдэг. Энэ нь санах ойн санаж байгаа хэсэг нь хүний тархитай адил.
Удирдлагын хэсэг: Энэ хэсэг нь оролтын хэсэг, санах ойн хэсэг, үйлдлийн хэсэг болон гаралтын хэсгүүдийг удирддаг. Энэ нь хүний гол судасны тогтолцоотой адил.
Гаралтын хэсэг: Компьютерийн үйл ажиллагааны үр дүнг гаргадаг мөн хүмүүс үүнийг ойлгодог. Энэ бол хүний гар болон амтай адил.
Тэдгээр 5н хэсгийг компьютерийн үндсэн 5н хэсэг гэж нэрлэдэг.
Удирдлагын хэсэг ба үйлдлийн хэсэг нь аль нэг хэсгийг боловсруулдаг, тэдгээрийг төвийн боловсруулах төхөөрөмж(CPU), эсвэл боловсруулах төхөөрөмж(PU) гэж нэрлэдэг. Оролт ба гаралтын хэсгийг багаж төхөөрөмжтэй хамтад нь хэрэглэдэг мөн нэмэлт санах ой юм. Түүнчлэн санах ойг дотор нь үндсэн санах ойн хэсэг ба туслах санах ойн төхөөрөмж гэсэн хэсэгт хамааруулан эдгээр функцуудыг хуваадаг.
 RAM (шуурхай санах ой)
Шуурхай санах ой нь өгөгдөл бичих болон унших боломжтой. Компьютер унтарсан үед ч өгөгдлийг хадгалдаг. Энэ нь тогтворгүй байдаг. Хаягыг шуурхай санах ой заадаг. Үндсэн санах ой мэдээлэл бичих болон үйл ажиллагааг хийх, унших гэх мэт.
Шуурхай санах ойг дотор нь  динамик шуурхай санах ой ба синхрончилсон динамик шуурхай санах ой гэж ангилдаг.
DRAM (Dynamic RAM)- Динамик шуурхай санах ой
Битүүдээр илэрхийлэгддэг. Конденсатор цэнэгтэй байвал 1 гэсэн төлөв, цэнэггүй байвал 0 гэсэн төлөвтэй, хэлхээ энгийн учир RAM(шуурхай санах ой) нь бага зардлаар их хэмжээтэй багтаамж бий болно. Гэсэн хэдий ч конденсаторын цэнэг хадгалалт нь урт хугацааны дараа алдах учир санах ойг тэжээдэг тогтмол интервис байна. Энэ нь үйл ажиллагааг урьдчилан сэргийлэх юм. DRAM нь нэг удаа хадгалагдсан үндсэн хэсгийг ашиглана. Принтер нь бусад төхөөрөмжүүд болон оролт гаралтын хэсгүүдийг агуулдаг.
SDRAM (Synchronous DRAM)-Синхрончилсон динамик шуурхай санах ой
Мэдээлэл харилцаа холбоо технологийн хөгжил дэвшлийн улмаас процессоруудын ажиллагааг их хэмжээгээр сайжруулах, динамик шуурхай санах ойн үйл ажиллжагааны хурд нь процессоруудын үйл ажиллагааны хурдыг хадгалах болон үл хадгалах хэсгээс бүрдэнэ. Энэ шалтгааны улмаас динамик шуурхай санах ой дээр процессорын үйлдлийг цаг зааж өгдөг дохиог суулгасан. Энэ дохиотой нэгэн зэрэг байхаар будлиантай хаягийн үзүүлэлтийг багасгадаг. Ингэсхээр өндөр хурдтай ажиллаж динамик шуурхай санах ойг хөгжүүлэх боломжтой болсон. Динамик шуурхай санах ойг өөрөөр сихнрончлох динамик шуурхай санах ой гэж нэрлэдэг.
Статик шуурхай санах ой
Статик шуурхай санах ойн хэлхээний холболт нь триггерээс үүсдэг. Триггерүүд нь оролтын гүйдэл болон өмнөх оролтын гаралтыг тохируулж байдаг ба 0 болон 1 үед хэлхээг залгаж салгадаг. Компьютерийг унтраахгүйгээр санайх ой дахь  өгөгдлийг дахин шинэчлэх шаардлагагүй. Гэвч статик шуурхай санах ой нь хэлхээг төвөгтэй болгодог. Учир нь санах ойн багтаамж нь динамик шуурхай санах ойгоос бага ба өртөг өндөр байдаг. Гэхдээ боловсруулалтын өндөр хурдтай ба тоолууруудыг агуулдаг үндсэн хэсгийг хадгалах болон боловсруулдаг төхөөрөмжүүдийг хэрэглэдэг.
Үндсэн санах ой
Үндсэн санах ойд хагас дамжуулагчийг ашигладаг. Үндсэн санах ой нь эхэлсэнээсээ хойш програм болон өгөгдлийг хадгалдаг, мөн компьютер унтарсан үед ч мэдээллийг алдагдалгүйгээр хадгалж байдаг. Үндэсэн санах ойг дотор нь mask үндсэн санах ой болон дахин програмчилдаг үндсэн санах ой  гэж ангилдаг.
MASK шуурхай санах ойг үслдвэрээс нь щифрлэдэг ба програмчлал болон өөр өгөгдлийг нь бичсэн байдаг. Хэрэглэгчид програмын өгөгдлийг нэмэгдүүлэхийн тулд хэрэглэгчид хүсэлт илгээдэг.
Дахин програмчилдаг үндсэн санах ой- үндсэн санах ойн төрөл болон дахин програмчилдаг үндсэн синхрончлолт санах ой нь өгөгдлийг юу ч үгүйгээр ганцхан удаа бичиж хадгалан байдлаар үйлдвэрээс нь зааж өгдөг ба нэг л удаа програмчилдаг.
Дахин програмчилдаг үндсэн санах ой нь дараах 3н төрөлтэй.
1. Програмчилдаг шуурхай санах ой-өгөгдөл нэг л удаа бичигдэнэ.
2. Арилгаж програмчилдаг шуурхай санах ой- хэт ягаан туяа болон цахилгаан гэрлээр дахин бичиж арилгадаг.

3. Цахилгаанаар арилгаж програмчилдаг шуурхай санах ой-Энэ нь программ хангамжийн болон цанилгаан хүчдлээр дахин бичиж арилгадаг.
Техник хангамж
Компьютерийг бүрдүүлэгч техник хангамжийн фунцыг ерөнхийд нь дараах таван ангилалд хуваадаг.
·         Оролт
·         Санах ой
·         Үйлдэл
·         Удирдлага
·         Гаралт
Дараах зүйлс нь доор дурьдсан хэсгүүдийг хэрэгжүүлдэг.
Оролтын хэсэг: компьютерийн үйл ажиллагаанд зориулж өгөгдөл болон программыг оруулдаг. Энэ нь хүний нүд болон чихтэй адилхан.
