COMPUTER COMPONENTS

COMPUTER COMPONENTS

A guide to the components inside my computer hello and welcome to video we're going to show you what the major components inside your computer are and tell you a little about what each of them do guiding us on this tour will be Phil Borton of East a technology support in brighton. Step 1 the major components the major components of a computer are the motherboard the CPU or central processing unit ram or the random access memory the graphics card the power supply the hard disk or hard drive the optical drive also known as a CD or DVD drive. Step 2 hardware and software all of these components are usually found with in  the Tower of a desktop computer. They are referred to as hardware can be thought of as the actual physical components that go into the computer software refers to the programs and systems that operate within the hardware. Step 3 the motherboard the motherboard is the heart of the computer it is the largest and most fundamental component of a pc and every other component is attached to it in some way. This is because all the different components used the mother board to communicate and work with each other the motherboard has a series of slots sockets and connectors for attaching the components of a pc in most cases the memory accessory cards and CPU are installed directly onto the motherboard. The drives and peripherals communicate with the motherboard through wired connections there are a wide range of motherboards to choose from they different features speed capacity and the CPU supported. They also different size shape and layout this is commonly referred to as the form factor step for the CPU stands for central processing unit. This is the brain of the computer and is often referred to as the processor or the chip. It is found under a heatsink and fan directly on the motherboard the CPU directs coordinates and communicates with the other components and performs all of the thinking. It is not really thinking what a CPU actually does it perform mathematical calculations it is the software that people write that translates these calculations into useful functions for us. Step 5 RAM stands for random access memory and comes as modules and predefined amounts. It is also found directly on the motherboard and usually in one two or four slots the memory chip store information temporarily for short term used by the CPU.  RAM is used to store information for files that are actually being used by the CPU at any given time the computer.
RAM memory is an entirely different thing from the hard disk memory the hard this stores information permanently for long-term use. Step 6 the graphics card the graphics card or video card translates information into the graphics and tax that appear on the monitor screen most motherboards now include a slot specifically designed for the graphics adapter called the AGP slot. This stands for advanced graphics port modern graphics adapters usually incorporate some memory write on the card to improve their performance. Step 7 the power supply this supplies power to the other components which is why it has so many wires coming out of it is usually positioned at the back top corner of the computer case the power supply has a fan built into it to keep itself and the computer cool. Step 8 the hard disk a hard disk which is also called a hard drive is much like a filing cabinet the programs and data is stored on the hard disk and the computer accesses them as they are needed when the computer accesses the hard drive. It is reading and moving the stored information into the ram memory that memory is the temporary workspace however the original file is still on the hard disk and has left undisturbed until the file is saved when the computer stores or saves information it writes a data to the hard disk that process results in the old file being replaced or modified with the new information if you save data to a new file or install new software. The information is written to the disc in an available unused portion of the disk. Step 9 the optical drive the optical drive is often called a DVD drive or a CD drive it sits at the front of the computer for ease of access and use a laser to read and write information to CDs and DVDs done.


What is ICT ?

What is ICT ?
Hi my name is Even Huavan . Hi my name is Chris horn and we want to talk to you about the ICT sector in Ireland. ICT stands for information and communications technology and that means that covers all of the technologies and businesses involved in the creation and processing of digital information that includes all fines of computing from building web pages to write and software to control a rocket from assembly the home computer to managing a complete office computer system from creating special effects for the film to designing the technologies broadcast TV and radio across the globe from studying the appropriate computer equipment to customer to providing the support needed to ensure the successful use of a new software system in a large organization. This is big industry really big in fact it’s the largest business in the world and it’s growing all of the time. Why well because as it’s heart it’s concerned with making life easier and better for everyone of us.
Hi I’m Lionel Alexander and the vice President and managing director of Hewlett-packard manufacturing here in the league slip kill their the ICT sector is a very key sector that not only drive the economy and the future Ireland but more importantly is charging the lifestyle of people every day in Ireland there over 70000 people working in over 1300 firms directly involved an effective. ICT to use a big  part of our economy much bigger than it is in the UK or most the rest of the world Ireland a tiny country beraly visible on the globe is one of the top three exporter of software and the world neither 10 top software companies in the world have significant operations here Ireland is home to many global players across all city business areas such as internet space data storage semiconductors telecommunications software and computer  systems with instantly recognizable names such as Intel, Dell, Microsoft, IBM, Apple, HP, Google, Ericsson, Sap, Yahoo and even Facebook the sector accounts for approximately a third of the country’s expert which is hugely important for or economy. By any measure the ICT sector has been a significant drive in the arch economy whether in terms of employment output for the creation of wealth as well  as been engaged in a range of business functions the provide the enabling technology to other sectors it has been a course of successful Irish enterprise an d startups and has contributed men stage the economic success of the country  in church  the ICT sector Ireland can boast world-class industry achievement one of the main reasons we have such a strong presense in the sector’s equality and diversity of our workforce the location of the world’s top level software companies in Ireland has meants the critical mase of technical and professional expertise has been reached in the sector the availability of highly skilled individuals are both graduate and senior level positions allows software companies to access a group of people. That is essential to achieve growth in the industry we also have a lot of qualified people from a wide range of nationalities who can contribute their technical knowledge and skills and their native language your selves  the ever-increasing need to provide services globally from operations based here recent figures and students entering carrot level 2 arising demand for engineering and technology courses we are now realizing that the world needs more people who are technologically we’re in every industry in sector the National skills strategy compiled by the expert group on future skills needs has found that the requirement to technical knowledge will rise across almost all occupations in the future. Even is times of rising unemployment demand for highly qualified graduates in discplines including computer science and engineering is expected to continue. This is also true or of the supporting roles which the technology depends the current economic downturn may effect the timing of that demand but it’s unlikely to effect the overall trend we as a nation let’s ensure that remains one of the best performance in terms of producing people. Who  combined their technical know-how from the science engineering technology areas. People include the development of ICT skills into their career planning will always be in a stronger position to adapt to the charging world connery and ensure that Ireland’s ICT that there continues to hold this position on the world stage.
My name’s Jim O’Hara the general manager of Intel and are kids coming to the system today who have an interest in science engineering and technology should have no fears about the future of working in that industry here in Ireland so if you want to have an aspiration that’s beyond essentially a good job and a good career think  about the aspiration of being involved in an enterprise that makes a difference across the whole globe. Intel in Ireland and companies like intel and Ireland have challenge on their hands and that’s to continue  to help Ireland fast be nimble because we’re operating on a global stage and Ireland needs people working in engineering and technology it needs the best brains working in those environments to that Ireland as a nation can prosper and grow the future is charging.

ICT is charging the world it’s going to change the way people consumed in the knowledge that the way people distribute the knowledge and the way people use their knowledge. If you want to charge the world and if you want to make a difference. Choose ICT as a career band.

Giving Effective Class Presentations

Giving a class presentation may make you feel quite anxious. However, with preparation, you can deliver an organized and polished presentation. Giving an effective class presentation involves working through four stages:

      Preparing the content




Preparing the content

An excellent presentation starts with excellent content. For your presentation to be a success, identify why you are speaking about your topic and to whom you are delivering the message. Gather support for your topic, organize your points and write a draft of the presentation. Plan how you will present, prepare speaking notes and create audiovisual aids.

Analyze the assignment

First, examine the assignment your instructor has assigned. The following questions may help you get started.


      What are possible presentation topics?

      Do you provide information about a particular topic or try to persuade people to do something?

      Does your instructor want you to do research to back up your points or can you rely on your own experience?

      Are you required to work independently or in a group?

      Are you expected to have audience participation?

      What types of visual aids are you required to use?

      When is the presentation scheduled?

      How long do you have to present?

      Do you have to hand in a paper on the topic you present?

If you are not sure about the requirements, ask you instructor.




Analyze the audience

In addition, analyze your audience. You are giving a class presentation, so your classmates and instructor are present. Think about who they are.

      How interested might they be in the topic and how could you pique their interest and make the information relevant to them?

      What do they know or not know about the topic you will present?

      What questions might they ask that you might need to address in the presentation?

Gather support for the topic

Your instructor may require that you research your topic in order to support the points in your presentation. If so, find articles, books or web sites related to your topic. Check out the MRC library's web page. If you are unfamiliar with research, ask a librarian for help. If you are required to provide a list of sources, make sure you record the bibliographic information. Once you have gathered sources, read through them and take notes or mark important information.

Create an outline and write a draft

It is important for your presentation to be well organized. Jot down your ideas and organize them into an outline. Then, write a draft of your presentation. Writing a draft helps you clarify your thoughts on the topic, become familiar with the topic and decide on appropriate transitions between points. You can use this draft to help you write a formal report if you are required to submit one. When you write the draft, pay particular attention to the introduction. In the introduction you gain the audience’s interest, state the purpose of the presentation, and an agenda or outline of your major points. In the body of your draft, make sure you use clear transitions that will indicate to your audience you are moving from one point to another. Include in the draft a conclusion or summary.

Devise a presentation plan

Once you are clear on what you want to say in your presentation, you can plan how you will present. A presentation plan helps you organize your time, know when to incorporate activities for the audience to do, and decide on the types of audiovisual aids to use. Look at the example of a presentation plan in Appendix A at the end of this document. Note that each section of the presentation has an estimate of the amount of time it will take to complete, a note of the type of audiovisual aid you will use, and what type of activity you will do, if applicable.

Prepare speaking notes

If you know your material well, you might use the presentation plan to prompt you for what you want to say during the presentation. You might, though, feel more comfortable using speaking notes to jog your memory. Speaking notes summarize points in your draft and are more detailed than the presentation plan. In the presentation, you glance at the notes and then elaborate on the points from memory. Your audience will find it easier to pay attention to you if you talk to them rather than if you read to them from a draft of your presentation.


Create or gather audiovisual aids

Ideally, you will use at least one type audiovisual aid in your presentation. You may want to display books, posters and brochures that provide more detailed information about your topic. You might show a video or slide show. You may provide a handout or create overheads the audience will use to follow along as you present. Ideally, you should have alternative audiovisual aids as a backup should equipment failure occur. For example, suppose you intend on using a LCD projector and laptop for a PowerPoint presentation. As a plan B, have overheads or handouts available as an alternative to the more sophisticated technology. Use words on overheads or PowerPoint slides sparingly; follow the 7 X 7 rule: no more than seven words per line and seven lines per overhead. The audience can then quickly take in the information when you introduce the overhead and then focus their attention on what you say rather than on reading fine print on the screen.

Practicing the presentation

Gather your presentation plan, speaking notes, equipment and audiovisual aids and practice the presentation in a setting similar to where you will present. You might find it helpful to get feedback from someone you trust. If you would like feedback from a Learning Specialist, book an appointment. As a presenter, you should be well organized, have clear speech, use appropriate non-verbal behavior and use audiovisual aids appropriately. When practicing, use the presentation evaluation checklist in Appendix B at the end of this document as a guide.

Organization

When you start your presentation, aim to get the audience’s interest at the beginning by possibly citing startling statistics, using a brief story, or suggesting to the audience how the topic is relevant or useful to them. In the introduction, you also need to establish your credibility and should introduce yourself. State the purpose of your presentation and provide an outline the audience can follow. Consider putting the outline on an overhead, flipchart paper or chalkboard.

In the body of your presentation, make it clear to the audience when you are moving from one point the next. You can emphasize a transition by pausing briefly before starting on a new point, pointing to the next item on the outline on the board or flipchart, and use transition words like "Next, I want to talk about…", "The second point I want to make is…", and "Now that I have finished talking about causes, I will move on to…".

At the end of the presentation, summarize and conclude your main points. Check that you have completed the presentation in the required time. If not, you need to go back to your presentation plan and make modifications. If you have time remaining, decide on which points you could expand on or what activities you can include. Conversely, you may have to reduce or eliminate points of less importance.

Speech and voice

When practicing, you also need to check your speech and voice. Have someone sit at the back of the room and check whether you speak loudly enough or you pronounce your words correctly. When speaking, vary the rate of your speech depending on your purpose. For example, speak slowly when introducing a main point. Pause briefly between points or for emphasis and avoid filler words like "umm" or "ahh". Also, sound enthusiastic and excited about the topic.


Nonverbal behavior

Appropriate nonverbal behavior helps to maintain your audience’s interest. Try to have good posture and natural facial expressions. Face the audience and have eye contact. Move your hands and move around the room.

Audiovisual aids

Before you start your practice presentation, become familiar with the equipment you plan on using. This will reduce your anxiety and make your presentation more professional. When you use an audiovisual aid such as a video, introduce it and explain why you are using it. If you use handouts with detailed information, summarize rather than read from them and give the audience an opportunity to skim the handout before you start to talk.

Making final preparations

You have prepared the content thoroughly and practice your presentation. Before the presentation, you need to organize your materials, deal with anxiety, check the equipment, and dress appropriately.

Organize your materials

The day before the presentation, gather together all the materials you will need for the presentation. If you are working in a group, consider having one person take responsibility for ensuring all the necessary material is placed in a box and brought to the room you will present in. Your group might brainstorm a checklist for that person to use.

Check equipment

When you practiced the presentation, you should have become familiar with any equipment you will use during the presentation. Arrive early for your presentation and ensure the equipment is working properly.

Dress appropriately

Consider your audience and purpose when planning what to wear to the presentation. For example, if your audience is a group of business students, consider wearing clothing appropriate for a business setting.

Deal with anxiety

Anxiety is a natural reaction to public speaking. A moderate level of anxiety is actually beneficial in that it motivates you to work hard and try your best. Remind yourself that you are thoroughly prepared and giving a presentation is good experience you can apply in the work place. Use relaxation techniques, such as deep breathing or meditation, to keep you calm. If you feel you anxiety level is extreme, consider talking with a counsellor about anxiety management techniques.

Delivering the presentation

The moment has finally come to deliver the presentation. Remember, you have analyzed your audience, gathered support for your topic, and planned how you will present. You have practiced your presentation several times and taken care of the last minute details. You will probably find that once you start delivering the presentation you will be calm and probably enjoy the experience. After you present, think about what you did well and what you could have done differently. Think of the experience as an opportunity to learn new skills or improve an existing skill set.
