Linux  is usually used to install in embedded systems, mobile phones, some kinds of watches, desktop computers, laptop computers, netbooks, and supercomputers. Nowadays, Linux has been used to be an operating system in netbooks with the two kinds of devices, which are ASUS Eee PC and Acer Aspire One. Brazil, Russia, China, India, Spain, France, and Germany has been using Linux for various kinds of purposes. For example, Linux has been developed to be used in educational organizations and other official organizations. 3. Mac OS X has been developed and owned by Apple Inc. Mac OS X became the second most famous operating system in 2009 in terms of the usages of the Internet connection. Also, Mac OS X includes many different languages. For example, English, Japanese, French, German, Spanish, Portuguese, and Italian are available. There are four main types of operating systems, which are “Real-time Operating Systems”, “Single-User/Single-Tasking Operating Systems”, “Single-User/Multitasking Operating Systems”, and “Multi-User/Multitasking Operating Systems”. •	The first type of operating system is “Real-time Operating Systems” or “RTOS”. RTOS is also known as Embedded Operating Systems. A real-time operating system runs real-time application. Also, a real-time operating system support only single-tasking. A real-time application is an application that responses to the input extremely fast. BeOS, ChorusOS, eCos, FreeRTOS, ITRON, LynxOS, MicroC/OS-II, Nucleus, Nut/OS, OS-9, OSE, OSEK/VDX, OSEKtime, pSOS, QNX, RMX, RSX-11, RT-11, RTOS-UH, VRTX, VxWorks, Windows CE, RTLinux, and RTAI are examples of Real-time Operating Systems. Real-time applications are used in medical diagnostics equipment, life-support systems, machinery, scientific instruments, and industrial systems. •	The second type of operating system is “Single-User/Single-Tasking Operating Systems”. This type of operating system allows users to run a single task at a time. Printing a document, writing a file to disk, editing a file, and downloading a file from a network server are examples of task for a computer user. A small and simple operating system can manage only a time. MS-DOS is an example of single-user/single tasking operating systems. This type of operating system is usually found in the Palm handheld computers. •	The third type of operating system is “Single-User/Multitasking Operating Systems”. This type of operating system allows users to run many tasks at a time. Microsoft Windows and the Macintosh Operating System are the examples of this type of operating system. This type of operating system is usually found in personal computers. Also, it can be used in various kinds of work. •	The forth type of operating system is “Multi-User/Multitasking Operating Systems”. This type of operating system allows users to run on a terminal server. Each user’s applications run within their user session on the server separate from all other user sessions. A terminal client is the software that makes a user session possible. UNIX, VMS, and MVS are examples of multi-user/multi-tasking operating systems. MVS is used in mainframe operating systems.

 Question 2) What operating systems should install on your netbook?   Answer : Windows 7 and Linux are the two popular operating systems that are used in netbooks. Nowadays, Windows 7 is recommended to install on many new versions of netbooks because of the three following reasons. The first reason is that Windows 7 can provide lifetime for netbooks longer than previous operating systems. The second reason is that netbook users will be able to access into the network more convenient. The third reason is that Windows 7 does not need power to run machines compared to other previous versions of operating systems. Acer Aspire One D250, EasyPC E790, Lenovo Ideapad S12, Toshiba Satellite U505 and M505, HP Mini 311, gScreen, iPhone 3G, Sony VAIO X, and Samsung N130, N140, and N150 are examples of netbooks which use Windows 7 as an operating system. 2.1) Acer Aspire One D250 is a netbook that provides the two operating systems, which are “Windows” and “Android”. 2.2) EasyPC E790 is a netbook that provides only one operating system, which is “Windows CE 5.0” or “Androud”. 2.3) Lenovo Ideapad S12 is a netbook that provides only one operating system, which is Windows 7. 2.4) Toshiba Satellite U505 and M505 are the two versions of netbook that provide Windows 7 as an operating system. 2.5) HP Mini 311 is a netbook that provides only one operating system, which is Windows 7. 2.6) gScreen is a netbook that provides only one operating system, which is Windows 7 Home Premium. 2.7) iPhone 3GS is a netbook that provides only one operating system, which is iPhone OS 3.1.2 (build 7D11), released October 8, 2009. 2.8) Sony VAIO X is a netbook that provides only one operating system, which is Windows 7. 2.9) Samsung N130, N140, and N510 are netbooks that provide Windows 7 Starter Edition.

Assignment 3: Twitter http://twitter.com/Benyaphaben '''Question 1. How is Facebook and Twitter the same?''' Answer: The first similarity between Facebook and Twitter is that a user can update a current status. The second similarity between Facebook and Twitter is that a user can find friends and add/follow friends via the tool of Facebook and Twitter. The third similarity between Facebook and Twitter is that a user can post a picture into those websites. Question2: Why do you think Facebook is worried about competition from Twitter? Answer: Perhaps the registration process of Twitter is not that complicated like Facebook. On Twitter, a user fill the personal information in a few boxes, but on Facebook, a user has to fill the personal information in many boxes. Also, the functions of the Twitter website can be used very easily. Therefore, these two reasons may be an answer for this question. A twitter user can follow many main news reports from BBC, NYTIMES, and Financialtimes very easily. A twitter user will be able to hfollow celebrities and Prime Misters of Thailand or the United States of America. Subscript text
