Assignment 3 task 2

My friend has started using her computer for gaming and there is slow response times and poor video she has asked that I help her improve the quality of her gaming experience so I will suggest a few things that may help her with her problems

Firstly I would suggest a graphics card. A graphics card is installed into a computer and is responsible for rendering the image that appears on the screen. Graphics cards can cost from £20 to £2400. I would suggest a graphics card because it is great for gaming and video also it will improve the overall gaming experience. A graphics card can make your images more HD (High Definition) and is popular for mainstream gaming.

I have chosen a graphics card which costs £269 and would improve my friends quality of gaming as it is 2GB of memory which helps give good resolution thus realistic graphics.

Secondly I would suggest a new monitor. A monitor displays graphics and is like a TV but displays the graphics better. A monitor with good resolution is also needed because it will sharpen and brighten the image which appears on screen. A monitor with HD (high definition) will improve the graphics because they will be more defined also a she should get a monitor which is a suitable size such as 22”-24” is perfect for gaming.

I have chosen a monitor which costs £99.99 and will improve my friends quality of gaming because the monitors an appropriate size and also has response time 5ms

Thirdly I would suggest a new ISP. An ISP (internet service provider) is a company that provides your access to the internet. This will improve the performance of the game. I would recommend a service provider that offers around 30 MB speed so that you’re gaming is faster and better.  

I have chosen the ISP with 30MB which costs £5 per month. It would be suitable for my friend

Finally I would suggest a RAM. A RAM is random access memory, it is computer storage. I would suggest this because a memory upgrade can make your computer run far better. It over speeds your media for faster write times and would be useful for storing you’re saved games so that you can play much more.

I have chosen a 4GB RAM which cost £54.99

   Internet and email

Sky is a service provider and is the top selling throughout the uk. For £5 a month you can have upto 20MB speed and unlimited downloads. there is a contract of 12months which  means you will pay £60 for the year. when you sign up for the package you get a wireless router and free evening and weekend calls, also if you are a sky TV customer you pay only £3.75 per month. i think this is a good deal because of the cheap price and the actualy things that are being offered

Transfere large video files

This product is £139.99 and had good memory it is a good product to buy and is small and compact it has a good capacity of 2TB. It includes a network base and a hard drive and has a very quick start drive. It is a good product to but to transferring large files from one computer to another.

For £328.99 you get the printer and the netbook.  The printer is wireless and you can print using your somputer or mobile phone, it also has a built in scanner which means it is more compact that having to separate items.

Assignment 2

I have recieved a phone call from my friend asking for my help. Her son is visually impared and has diffaculty using the software in its default setup so i am going to shows ways that will help him.

                             This shows the computer desktop before i rearranges any of the icons.

                I right clicked on the desktop and chose to take off the auto arrange icons option.

                                      I arranged the icons wherever I wanted to put them.

I decided to change my icon size on the desktop which could help someone with vision problems. so i right clicked on the desktop again and clicked on view larage icons.

This shows the large icons.

I am now going to show what i did to add in the font style and other commands to the quick access tool bar

the 3 previous screen shots show how i added different icons like font into the quick access tool bar.

This is a screen shot of the font style added.

I am going to show the magnifier tool which will make everything on screen closer up

this is one of the magnifiers which magnafies anything which you scrool over with the lense

the magnifie shows everything up close at the top of the screen

this shows that the magnifier zooms up the screen compleatly

this print screen shows the resolution being changed.

 

As you can see previously made many different changes to Microsoft Word, the desktop and the display which will help my friend’s son. All the changes I have made will help him be able to use a computer easier because it will be like he is not as visually impaired.

Firstly I changed the size of the desktop icons and rearranged them; this meant that the son would be able to see them better because they are bigger than normal, I changed them to large. I also put the icons in alphabetical order which meant that he would be able to find them more easily because they aren’t in a random order all over the screen.

Secondly I added font style and a few other tools to the quick access tool bar, I think this would be beneficial for my friends’ son because he will not have to look for what he needs on Microsoft word as they will always be at the top of the screen.

Thirdly I changed the resolution on the computer so that the text and images were more defined this means that the boy would be able to see things more clearly although all colour depths may not be available this will benefit him greatly.

Lastly I minimised the ribbon on Microsoft word so that there would be nothing else on his screen until he needed it. Although as I said before I put different things in the quick access tool bar so that he would not always have to go looking for different tools.

Data Flow Diagram

Software

Microsoft windows XP is an example of system software. 
System software refers to the files and programs that make up your computer's operating system. System files include libraries of functions, system services, drivers for printers and other hardware .System software controls a computer’s internal functioning, it also controls the monitor and speakers and also storage devices. The programs that are part of the system software include assemblers, compilers, file management tools, system utilites, and debuggers. The system software is installed on your computer when you install your operating system. You can update the software by running programs like "Windows Update" and "Software Update"

A word processor is an example of application software. Application software is also known as Apps. Application software is computer software that includes database programs, word processors, and spreadsheets these are all office applications, they allow us to make documents with text and pictures. there is other types of application software such as games software, games software is an "app" that you can design games on. Application software can not run with out operating software.

Software utilities are things like firewalls that protect our computers from virus. there are many types of software utilities such as firefox click and clean or Win HMR. these types of things keep our information secure and makesure know one can hack our computers or take personal information. firewalls also allow computers to preform tasks quicker because they are keeping harmful material from slowing the computers down.

Hardware components

The processor tells your computer what to do and when to do it, it decides which tasks are more important and prioritizes them to your computers needs.

RAM means ransom access memory. the RAM provides space for your computer to read and write data to be accessed by the CPU (central processing unit). The more RAM you have on your computer the faster the speed on your computer is.

devices for network connection

3G stands for third generation. it allows the signal to carry far larger amounts of data, this meant that 3G mobile phones could access the internet at reasonable speeds, it also allows you to use video calls on your phone. As 3G suggests there was 2 pervious generations before this. There are many application you can use if you have 3G such as mobile internet and mobile TV. 3G has higher data speed and enhanced audio and video streaming. To use 3G you need to subscribed to a service provider to get the network connectivity

There is also a 4G which means fourth generation is basically the extension in the 3G technology with more bandwidth and services offers in the 3G. With 4G you get ultra broadband internet access.  4G has data transmission speeds as high as100 Mbps. 4G can be used with mobile phones and wireless computers. 4G is a wireless broadband.

Bluetooth is a way of exchanging data wirelessly over short distances. Using a special radio frequency to transmit data, it creates a short range network. It is very secure and can connect up to eight devices at the same time. Bluetooth can be used for sending images, videos or music using a mobile phone with Bluetooth or a laptop with Bluetooth. Bluetooth is very secure as you have to accept a Bluetooth invitation if you want something to be sent to you or something of yours sent to others.
