OPERATING SYSTEMS OVERVIEW

An operating system is a system that controls the computer. However not all computers requires an operating system. Basic computer system such as the ones in microwaves doesn't require an operating system this is because a microwave serves a straight forward function. As for our desktop, laptops, smartphones etc. they need an operating system as they can be used for a variety of purposes unlike the microwave. The operating system is used to manage how the devices work. It manages all the hardware and software on the computer.

The early operating systems didn't have a graphical user interface also known as GUI. Instead they had a command-line interface which isn't very user friendly as the commands have to be type out for every single function. Nowadays all operating system comes with a GUI which is user friendly and therefore easy to use as functions can be carried out by a click on the mouse.

The modern and common operating systems are Microsoft Windows, Apple Mac OS X, Linux, IBM z/OS, Android, IOS and BSD. Every operating system is different as they have a different look and feel to it. Users may feel unfamiliar to them at first but it time they will get used to it as these systems are designed to be user friendly. The basic principle of all operating systems remains the same.

Microsoft Windows was created in the mid-1980s. There have been many different versions since then. The most popular ones are Windows XP, Windows Vista and Windows 7. All newly bought PCs comes with installed Windows operating system of different editions depending on the buyer. The Mac OS was created by Apple Inc. It is used on all Macintosh computers. The Mac OS X also has different versions depending on user. Among them are the Snow leopard, Lion and Mountain Lion. There is also the Mac OS X Server which is specifically used for servers. The majority of people use Windows instead of MAC OS, this is because MACs are more expensive and have limitations to hardware and software. However it does have its benefits such as it being less prone to viruses. The Linux OS is a unique operating system as it is free and can be modified and distributed by anyone.

OPERATING SYSTEMS MAJOR COMPONENTS

All though not all operating systems have the same structure, they do have common components. The major components of an operating system are:

Process Management

There are many activities going on in the operating system such as system and user programs and so the process management basically manages all these processes. It basically manages the creation, deletion of user system process, suspension and resumption of processes, mechanism for communication, synchronization processes and also for deadlock management.

Memory Management

The main memory basically serves as a storage that can be accessed by the Central Processing Unit (CPU). Programs that are executed remains in the main memory. The memory management actually Decides which process are stored into the memory, allocate and de-allocate memory space that are required and also keeps track of which section the memory are used. These files are stored into directories in the hard disk.

File Management

The file management manages files that are stored by the user. These files are stored in the secondary storage which is the hard disk and it serves as long term storage. These files are stored into directories on the hard disk. The file Management manages the creation, deletion of files and directories, mapping of the files on the hard disk and also backing them up.

I/O System Management

The I/O system management manages the input and output devices from the computer. Most input and output devices have a device driver and this driver knows the properties of these devices and what the I/O system management system does is basically manages what device driver goes to which device.

Secondary Storage Management

The secondary storage consists of disk and other media. Whenever a program runs, instructions and data are placed in the primary storage or cache and is referenced to the program because the main memory is too small and is only a temporary storage and therefore a second storage is required to back it up. The secondary storage management manages the space on the secondary storage, allocates the storage spaces for new files and schedules memory access requests.

Networking

The network is where processors communicate with each other. The design of the network requires connection strategies, routing and proper security.

Protection System

The protection system applies when there are multiple users using the computer. This is so that every user has his or her privacy and authority. It is a mechanism that prevents other users from viewing or making changes to others information such as access of processes and access of programs.

OPERATING SYSTEMS UNIQUE FEATURES

All operating systems have a common unique feature. They are able to do:

Program Execution

Operating system serves as a way where users can execute programs easily without hassle. The operating system does all the detail work of running the programs such as allocating, de-allocating memory and CPU scheduling whereas the user just has to click a button on the mouse.

Management of Device Drivers I/O

All programs need an input and it produces output. There are details of how the hardware works with the computer but the operating systems handle this for the user so that it is convenient. Users are unable to view the details of input and output of the hardware, this is efficiency and protection.

Manipulation of File System

The operating systemmakes it much easier for users to finish their task by writing into new files or input taken from other files. It also manages the speed at which the I/O connects with the program.

Communications

There are times where processes communicate with each other for information exchange beit on the same or different computer. The operating system handles this processes, however when information needs to be passed to other computers through a network, the user programs are able to handle this. The user program can be customized according to the specifics of the hardware involving the transits of messages and also provides the service interface to the operating system

OPERATING SYSTEM OF CHOICE(Microsoft Windows 7 Professional)

There are many good operating systems out there and currently the popular ones are Windows and MAC OS. Choosing an operating system actually depends on the users familiarity, skills and style. Not many people out there know how to use a MAC OS whereas for Windows, the majority does. My choice would be Windows over a MAC OSit is much cheaper, more software choices and also perform as well as the MAC. Windows also has the familiar start bar for ease of access, the taskbar where programs can be pinned on and also accessed with ease, No global menu such as the MAC OS as it is takes less time for navigation and users can also customize them, windows management where the OS will actually automatically adjust the window size based on the edge where user drag them, it also has a good support for multi monitors. It also has homegroups where it is easy to share files, devices and stream media with other Windows 7 automatically. Besides that is allows also browsing. The hassle of network configuration is eliminated and also the options for limiting access of files and folders. There is also a jump list where previous activities can be selected without navigating to them.Windows has libraries where grouping of files types can be done among different folders and devices.

Currently the latest is Windows is Microsoft Windows 7 and I would recommend Microsoft Windows 7 Professional 64 bit. For the 64 bit version, I would recommend having a 64 bit processor with 8 GB of RAM;this is so that it will be sufficient and optimal for the company as there are graphics design software and multitasking jobs involved. Microsoft Windows 7 Ultimate is unnecessary as it is designed for intensive international and network use and it is also more expensive. Microsoft Windows Basic and Home premium are insufficient as they designed for home use only. Both the Basic and Home Premium editions does not have Windows XP mode, does not have the ease of connecting to company networks and more securely Domain Join and finally it is also unable to backup up to a home or business network. Windows 7 features are the new taskbar, device recognition, Action center, problem steps recorder and Aero snap and shake.

Operating Systems Comparison

Microsoft Windows XP maybe outdated but it is still used by many mainly because it performs slightly faster and also does not require high specifications to run it. It can happily run on a 300MHz Pentium II with just 128MB RAM, however Windows 7 has a strong design is a pleasure to use but requires at least 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor for the 64 Bit version, 1 GB RAM (32-bit) or 2 GB RAM (64-bit), 16GBhard disk space (32-bit) or 20GB (64-bit) and a DirectX 9 graphics device with WDDM 1.0 or higher driver. As for running win Windows XP mode it requires an additional 1 GB RAM and also an additional 15 GB of hard disk space and also a processor that is able to do hardware virtualization with Intel VT or AMD-V turned on.Windows 7 was design to work with multi-core processors, 32 bit version supports up to 32 processor cores and the 64 Bit version support up to 256 processor cores. With today's standards, these processors wouldn't cost much and they are pretty much a basic standard in all PCs and so getting a Windows 7 would be an optimum choice.

Windows Vista had quite a number of problems such as speed and also supposedly shorter battery life for laptops. Benchmarks on boot times were done on these three operating systems and the results were surprising. Windows 7 came out as the winner followed by Windows XP and finally Windows Vista. As for file transfers, Windows 7 performed the fastest followed by Windows XP and finally Windows Vista. However when transferring large files like 1GB, Windows Vista beats Windows XP but the winner is still Windows 7. The same goes for opening small and big applications such as excel spreadsheets. Keep in mind that these benchmarks were run on a basic standard spec of this time. A lower outdated spec could make Windows XP a winner.

As for networking, Windows Vista has network map that displays a graphical view of all devices. The network setup is also useful for the user and it is also easier to search and connect to wireless networks. There is also status report on connection and a diagnose and repair option that will let Windows Vista fix the problem automatically. However for Windows XP, it still performs better in terms of speed over Windows Vista. Windows 7 on the other hand has all the features of Windows Vista and more. As stated before it has homegroups which makes networking much simpler, however this only applies to other computers with the same operating system. If the other computers have an operating system like XP or Vista, then the network configuration has to be done the old way. In terms of performance Windows 7 still comes out the winner over the two but keep in mind also that performance may vary depending on the hardware.

In terms of security, Windows XP fails and as result going online wouldn't be very safe as the security updates are not very assuring. The good side of it is that it isn't annoying as Windows Vista's User Account Control (UAC) would prompt the user whenever system changes are made, but then again these prompts could actually be a good thing as they give the user the option as to whether a particular malware is allowed to be executed. The UAC also works with Internet Explorer's Protection mode, limiting and avoiding writing on the registry without authorization. Windows 7 on the other hand has more customizable options in the UAC. There is a customization of how many alerts are visible and as a result less annoying to the user but still safe.

For mobility, Windows XP may seem to be a good choice over Windows Vista. Windows XP uses less power and therefore prolonging the battery life. However it doesn't have the power management system that Windows Vista has which allows the user the option to manage the power usage. But even with the power management system in Windows Vista, it didn't proved to be very effective. Overall Windows XP still performs better. As for Windows 7, it also has the power management options but also reduces repeated background activities. Besides that it also start its services when required such as the Bluetooth, it will not be activated unless a Bluetooth device is connecting. When there is not much work to be done, Windows 7 deactivates the rest of the CPU Cores leaving only one activated, this greatly reduces the amount of power being used and therefore the winner goes to Windows 7 again. Windows 7 Professional System Requirements are:

1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor

1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)

16 GB available hard disk space (32-bit) or 20 GB (64-bit)

DirectX 9 graphics device with WDDM 1.0 or higher driver

Music and sound require audio output

Internet access (fees may apply)

DVD/CD authoring requires a compatible optical drive

Windows XP Mode requires 2 GB of RAM (32-bit) / 3GB RAM (64-bit) and 15 GB hard disk space & Processor (hardware virtualization) Intel VT or AMD-V switched on

OPERATING SYSTEMS USER INTERFACE

All operating systems have a user interface so that users are able to interact, communicate with programs. The user interface is used to manage the way information is viewed and for users the input instructions and data. It is also used as a way for users to interact with software. There are three types of user interfaces. They are:

Command-Line Type Interface

This type of user interface is based on command language where users have to type a command to instruct the computer what needs to be done. The commands have to be remembered and correctly typed in order for it to work; there cannot be a single syntax or spelling error. The commands have to be typed one line at a time.Simple command language interfaces uses different names for different commands, however for advanced and complex command language interfaces, these sophisticated commands can be composed by the users and set them into primary commands. This basically reduces the typing of the user. There are some who actually prefer command line interface because it is faster but this only applies to those who have fast typing skills and remembers the commands very well.

Menu Type Interface

Menu based interfaces are different from command-line interfaces. It is easy to learn as it doesn't require users to remember and type in commands but instead, it is displayed in menu form and all that users have to do is select them although there may be some typing but it is kept to the minimum. Although mengraphicau type interface maybe simple to use it does have its limitations. It cannot have large choices such as the command line interface; thechoices will have to be grouped up.

Graphic Type Interface (Graphical User Interface)

The graphical user interfaces are designed in terms of visual and is considered user friendly. It consists of icons, objects and menus. All that the users have to do is click them with the pointer using a mouse. These icons and objects can be dragged also such as emptying aparticular file into the recycle bin. This type of interface is very easy to use as everything is presented visually and is easily recognizable and is the most commonly used.

APPLICATION SOFTWARE OF CHOICE

There are many good application software out there. Different application software serves for different purposes. As for this company, I would suggest a few them that would be efficient and useful. The application software are:

Microsoft Office 2010 (Professional Plus)

Microsoft Office is the most used software out there. This edition of Microsoft Office is the best and sufficient choice for the company. The previous editions are insufficient as it is intended for personal use and small business. The Professional Plus edition has Access, Publisher, Outlook with Business Contact Manager, OneNote, InfoPath, Lync and SharePoint Workspace which can be very useful for office use. There is improvement in Microsoft Office 2010 in terms of performance over the previous versions. Designs are tweaked slightly for ease and some of them are also customizable, like the ribbon.Microsoft Office also provides good support for users but the only downside of it is that it does not support other office software applications. Its features are: Co-Authoring, Conversation view, Broadcast Slide Show, Video Editing and Formatting and Microsoft Excel 2010 Sparklines. Beside that it has improved Ribbon, Microsoft SharePoint Workspace, Office Web Apps, Office Mobile, Office OneNote and Linked Notes.

Word 2010, Excel 2010, PowerPoint 2010, OneNote 2010, Outlook 2010 (With Business Contact Manager), OneNote 2010, InfoPath 2010, SharePoint Workspace 2010, Lync 2010, Access 2010 and Publisher 2010.

CONCLUSION

The Choices recommended here are best suited for this company. The Windows operating system is the best choice as it is most commonly used and also has potential for a much larger variety of applications. It may suffer from slight bugs and constant updating and protection but this can all be handled with the right applications. The MAC operating system is also not a bad operating system, it is said to be virus free but there are some who disagree.It's just that it is limited to hardware and applications that can be used in the future. It also cost a lot more to have a MAC computer and to upgrade it. However it also greatly depends on the budget, if the budget seems greatly a lot, Then going for the MAC operating system wouldn't be a bad choice either as there are many high end graphic design companies that actually use it such as Disney and Pixar. The Microsoft Home and Office 2010 is also a great software as it is also commonly used by many. This makes it easier for employees to dive straight into it and work. It has all the necessities for the company and is sufficient. The Adobe Creative Suite 6 Master collection is a choice as it has good and large amount of tools for graphic designers to work with. It is also a pretty much a software that is familiar to graphic designers. A lot of experimentation can be done with it and produce remarkable results. It may be a bit pricy but it's worth it. Google Chrome is the most used internet browser. It is significantly faster than the others and is easy to use. The Advance System Optimizer is good enough for the system as it will take care of all the necessities in order for the system to be stable. The Bitdefender Small Business Security is ideal for office use therefore making a good choice too. It will protect the system of an office environment from attacks making it a secure one. The system requirements of the PCs would be higher than a standard one as software like the Adobe Creative suite requires it. In order to have a good graphic design PC it must have good processing power to ensure smooth and fast performance. Laptops may also be used for work that is done outside of the office to ensure that one is not limited to a particular place for work. However for heavy duty designing, It is preferably to work in the office unless the laptops are high end ones but this will be costly also, so limiting a number of them will do.

USER INTERFACES SCREENSHOTS

(Command Line Interface)

(Menu Based Interface)

(Graphical User Interface (GUI)) (Windows 7)

WINDOWS 7 USER INTERFACE

Windows 7 user interface is very much like Vista's but with extra features

Taskbar

(Windows 7 Taskbar)

It is the best one yet. It will display a thumbnail preview of the opened application whenever the user moves the mouse cursor over the application on the taskbar.

JumpList

(Windows 7 Jump List)

When users right click on an icon that takes advantage of this feature, it displays previous activities with that particular program such as websites viewed on Google Chrome or documents previously opened on Microsoft Word.

Aero Peek

(Windows 7 Aero Peek)

It basically gives the user a clear view of what they want to open by moving the mouse cursor over the thumbnail preview. It then opens while making other opened windows transparent. Moving the mouse cursor away from the thumbnail preview will minimize the window again.

Pinning
