Evaluate the performance of a computer system. Explain and justify improvments that could be made to a computer system.

 

The computer system that I was asked to set up was a full desktop computer. Before I configured the system to meet the needs of any user the computer was not working properly. When I would turn it on nothing would work, none of the software was working and the files were all messed up.

There are many improvements that can be made to the computer. The first improvement I would make is that I would install a powerful fan system that will cool the computer components easily. The machine will then be totally silent while it is in operation, with no fan noise at all. Another improvement I would make is to the RAM, I would increase it. This will result in the increase of speed that the computer can process. I would also install new software on the computer that will enable me to create and watch videos at high speeds. Also if I were able to I would install new speakers in to the computer or have them attached separately. By doing this the out come of watching the videos that I have created and the videos that were all ready made will be much better than they would have been before. I would also install new camera hardware so that I can use it to make live videos or video calls. To make video calls however I may need to download software that will make the computer compatible for this.

 Recommend a computer system for a given business purpose. Justify your choice of computer system to meet a given business purpose.

There are many operating systems that are able to run Microsoft Office. The most common operating system is Windows.  Microsoft office and Linux are not usually compatible with each other, they are seen as oil and water, and they just do not mix. Now that technology has developed there are programs that can be downloaded on to the operating system that will enable Microsoft Office to work. This can be a hassle as the software will need to be downloaded and programs will need to be installed and to do all of this a technician may be required. This is why I prefer and recommend, Windows.  There are many versions of Windows operating system. The most common version at the moment is Windows 7. According to Windows, these are the top ten reasons why I should chose to use Windows 7:

A better desktop. Windows 7 gets you around your PC faster than ever. The taskbar has bigger buttons and full-sized previews—and you can pin programs to it for one-click access. Jump Lists provide shortcuts to files, folders, and websites. And Snap, Peek, and Shake give you easy (and fun) new ways to juggle all those open windows.

Smarter search. Type in the Start menu search box, and you'll see results instantly, grouped by category—documents, pictures, music, e‑mail, and programs. Search in a folder or library, and you can fine-tune your search with filters like date or file type—and use the preview pane to peek at the contents of your results.

Easy sharing with HomeGroup. Sharing files and printers on your home network should be simple. With HomeGroup, it finally is. Connect two or more PCs running Windows 7, and with a minimum of fuss you can start sharing music, pictures, videos, and documents with other people in your home.

Built for speed. Windows 7 has key performance improvements to take up less memory and run background services only when you need them. It's designed to run your programs faster and to sleep, resume, and reconnect to wireless networks quicker. And with 64-bit support, you can take full advantage of the latest in powerful 64-bit PCs.

Better wireless networking. Connecting to wireless networks on your laptop—formerly a bit of a hassle—now takes just a couple of clicks. Choose from the list of available networks in the taskbar, click one, and then connect. Once you've connected to a network, Windows will remember it so you can connect again later automatically.

Windows Touch. Use your fingers to browse the web, flip through photos, and open files and folders on a touchscreen PC—for the first time, Windows includes true multitouch technology. With gestures for zooming, rotating, and even right-clicking, it's a whole new way to work with your PC.

Plays well with devices. Device Stage, a new feature in Windows 7, works like a home page for things like portable music players, smartphones, and printers. When you plug a compatible device into your PC, you'll see a menu with information and popular tasks like battery life, how many photos are ready to be downloaded and printing options.

Watch, listen, and stream.‌ Internet TV, part of Windows Media Center, gathers programming from sites all over the Internet—shows, sports highlights, video podcasts, and more. Add a TV tuner, and your PC becomes a digital video recorder you can use to watch, pause, and record live TV. And with new features in Windows Media Player 12, you can enjoy your media library around the house—or around town.

Internet Explorer 9 and Windows Live.‌ Windows 7 unleashes the full power of Internet Explorer 9, from its stunning hardware-accelerated graphics to the ability to launch favorite websites right from your taskbar. You'll also get the many possibilities of Windows Live, free: create photo albums and movies, chat in HD, and share your stuff anytime, anywhere.

Nag-free notifications. Action Center, new in Windows 7, puts you in control of maintenance and security messages. You can turn notifications on or off for things like Windows Defender or User Account Control. If Windows needs your attention, you'll see a notification on the far right of the taskbar. Click it and you'll get suggested fixes for any problems.

Firewalls

The purpose of a firewall is to either block or allow incoming traffic to a network by selectively restricting access to the network.

Traffic is controlled by monitoring the many network ports. A network port is an identified doorway. It has its own address. A network port is used for communicating between programs, other communication systems or the programs that frequently pass through hardware ports. Network ports are often numbered. A standard network will assign a port number to all of the data it sends out. The receiving side will guard its self until it understands which program, on its system, to send the data to. It does this by checking the attached port number. There are two ways a port ways a port may send/receive data:

1.       Simplex – data is sent/received in one direction at a time

2.       Duplex - data is sent/received simultaneously in both directions.

These software networks ports can also connect to internal programs on single computers.

                Users currently operating with firewalls are most likely to notice that when certain programs load on computers or when they are started, a warning message from the firewall may pop up, warning the user that there has been an attempt by the program to create an outbound connection. The firewall automatically configures legitimate programs to allow program up dates and other routine tasks.

                 When configuring a firewall, you must be careful as it is possible to block access to recourses that are required. This can cause programs to not work properly. There are some cases where too many restrictions have been placed in the firewall settings that the internet has been disabled.

                The best choice is to refer to a qualified technician or a reliable expert if you need help making choices about how much access a program is granted or denied.
