Assignment 3

A friend has approached you for advice on purchasing a PC to work from home. You have asked a series of questions and obtained these answers.

I run database reports and use spreadsheets.

The first piece of software i would suggest to my friend for to run database reports and spreadsheets is Microsoft Excel 2010. It will make better decisions quickly with easy-to-analyze spreadsheets. Microsoft Excel is the also standard for business analysis.

Price: £119.99.

When you buy off Microsoft official website they will send you the package with secure box with the disk and serial code to download and install on to your pc.

My children may want to research on the internet and I will need to access work email from home.

The second piece of software i would suggest to you is. Microsoft Outlook Express 2010.  

Stay connected to your world with our most up-to-date e-mail and calendar tools. Stay more connected than ever before with Microsoft Outlook 2010.

Price: £119.99

When you buy off Microsoft official website they will send you the package with secure box with the disk and serial code to download and install on to your pc.

I need to transfer some large video files (at least 100Mb) which I need to store and run.

The third piece of software i would suggest to you is an External hard drive. It is great because some external hard drive can be either fitted into you pc or some can simply be connected to your computer via USB Port it that simple and give's you a whole lot more memory. If you want a high memory external hard drive (100mb Or 250mb or 500mb or more) there now even cheaper. There is even portable external hard drives.


Price: £69.99
Seagate 500GB External USB 3.0 Portable Hard Drive

I enjoy playing computer games.

The fourth piece i will show is a joystick. A joystick is very good for anybody who likes gaming and is very easy to use. Some Joystick's are cheaper than other's and some others are more higher priced more and likely the higher priced Joystick's are going to be PC and Console compatible and then the cheaper priced Joystick's are just going to be either PC compatible or Console only compatible. That why the higher priced Joystick's are better but are a good bit more than normal cheap Joystick's.












Higher Priced Joystick

Price: £70.10

Lower Priced Joystick

Logitech 942-000005 Extreme 3D Pro Joystick for PC

Price: £34.99

I take lots of pictures with a digital camera and I would like to transfer these to the computer and print them.

The fifth piece i will show is a all-in-one printer. Digital Camera are great when you have a printer that can print it out or even save it to your hard drive for later use. Now the all-in-one printer is great but they is other printers that are not as good and are also cheaper but if you want do what every want and have no promblems the all-in-one printer is the probably the best one to buy.


HP ENVY 114 e-All-in-One AirPrint Printer
Price: £249.95

Cost is not a big problem at this time.

If you want to go big and spend a lot of money then this is what you want to buy. An Apple Mac Pro starting at hefty £4,083.00 and if you the money to max it out with all the accessories then you will have a bill of £16,694.94. It certainly is very good looking but wondering is it worth all that money when it is only a desktop. But with its impressive specifications it comes with Two 2.93GHz 6-Core Intel Xeon “Westmere” (12 cores), 64 GB (8 x 8 GB), Mac Pro RAID Card, 512GB solid-state drive 4x, ATI Radeon HD 5870 1GB. It certainly sound good anyway.

How microsoft helps visually impaired

Imagine that you were suddenly deprived of all visual data and that the information. Blind or visually impaired people worldwide and the millions more who are otherwise print disabled, unable to process text because of learning, developmental, or physical disabilities, that is often what it feels like when having to access the same information the rest of us take for granted in books or on screen. I think Microsoft office is good for helping people who are Visually impaired and think that there products are also very good for Visually impaired people or anybody else who has learning or physical disabilities because it easy to use.
