Disadvantages of embedded Operating system?
Embedded operating system
An embedded operating system is an operating system for embedded computer systems. These operating systems are designed to be very compact and efficient, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run. They are frequently also real-time operating systems.
Examples of embedded operating systems could include the software used in Automated Teller Machines, Cash Registers, CCTV systems, jukeboxes, etc.
Features of Embedded Operating System
1-Embedded systems are designed to do some specific task, rather than be a general-purpose computer for multiple tasks. Some also have real-time performance constraints that must be met, for reasons such as safety and usability; others may have low or no performance requirements, allowing the system hardware to be simplified to reduce costs.
2-Embedded systems are not always standalone devices. Many embedded systems consist of small, computerized parts within a larger device that serves a more general purpose. For example, the Gibson Robot Guitar features an embedded system for tuning the strings, but the overall purpose of the Robot Guitar is, of course, to play music similarly, an embedded system in an automobile provides a specific function as a subsystem of the car itself.
3-The program instructions written for embedded systems are referred to as firmware, and are stored in read-only memory or Flash memory chips. They run with limited computer hardware resources: little memory, small or non-existent keyboard and/or screen.

One example of freeware is the web browser you're using. Firefox, Internet Explorer, and Google Chrome are all considered freeware.

What is the difference between a monolithic kernel and a microkernel?
* Maintenance is generally easier. Patches can be tested in a separate instance, then swapped in to take over a production instance. * Rapid development time, new software can be tested without having to reboot the kernel. * More persistence in general, if one instance goes hay-wire, it is often possible to substitute it with an operational mirror
What elements are common to both the Apple Macintosh and the PC?
Well both Macs and Pcs have internet connections. both come in mobile packages called laptops. Well even though I am a dedicated PC user I recommend a mac. today hackers and other cybercriminals go after pcs. There are only a couple hundred different malware that affect macs. and today you probably won't find them. people have stopped circulating them. I personally don't know why macs came first and then pcs dominate for twenty years. I think it was the fact new technology like digital cameras were first only available to PC users. Macs save money because they aren't nearly as vulnerable. Just take any spyware program. Most have alleast a couple hundred thousand definitions. that equates to a couple hundre thousand virus. and that's just spyware
What system controls the computer hardware?
System hardware is normally controlled by the operating system or driver code depending on the component and implementation.
What are the functions of an operating system?
The functions of an operating system include booting the computer and performing basic tasks. The operating system manages the keyboard and mouse. It provides a graphical user interface.
What is segment table in operating system?
Segment tables in computer graphics includes the length of corresponding segments in main memory. Each entry in the table contains the lengths, and to see if a segment is already in main memory, a bit is usually needed.
What is the purpose of operating system software?
Because Restaurant and bar management system software is a potential tool for the food and beverage industry to simplify its operations. It helps to automate most of the daily mundane tasks and improve productivity. The restaurant management software is a cost-effective solution to track the stock levels, orders, service standards and manage employees. Restaurant management software helps businesses to provide a personalized customer experience to each customer.
What was the first computer with an operating system?
The first operating systems were nothing like modern operating systems and were usually called batch monitors, because all they did was automatically ran jobs sequentially in batch mode. Computers of the time had no interactive mode of operation. Computer companies did not supply software of any kind with their machines, so it was usually up to the user (company, university, government office) to write all their own software. The first batch monitor/operating system was done in 1954 by MIT for their UNIVAC 1103. General Motors did one in 1955 for their IBM 701.
The first computer to come from the manufacturer with an operating system already installed is a different question.
Why Memory is required in the system?
Is to read things on the computer or to hold a paticular document
Without RAM, a CPU can not execute any code at all, or access any data. The Operating System must be stored in RAM or the CPU can not access the code necessary to run the Operating System. Also, files that the user is working on must be stored in RAM or they are not accessible.
What is response time in operating system?
Response time measures the performance of an individual transaction or query. Response time is typically treated as the elapsed time from the moment that a user enters a command or activates a function until the time that the application indicates the command or function has completed. The response time for a typical Dynamic Server application includes the following sequence of actions. Each action requires a certain amount of time.

Popular features include: A start menu or application menu (Windows, Linux) Multiple desktop workspaces (Linux, Mac OS X) Taskbar (Windows, Linux) or dock (Mac OS X, also Linux) to track favorite program shortcuts and active applications A desktop environment. Linux has GNOME or KDE (and a few others), Mac has Aqua, and Windows Vista has Aero. Desktop acceleration (Mac OS X, Linux using Compiz or similar, and Windows Vista Premium, Business, or Ultimate)
What is a 64-bit operating system?
The primary difference, in non-technical terms, is that a 64-bit operating system is able to access more memory. A 32-bit operating system can only access up to 4 GB of RAM. Applications are steadily demanding more and more RAM. Even if you place more than 4 GB of RAM in your computer, you won't be able to use it with a 32-bit system. So to use the newest and greatest apps, you will eventually need a 64-bit operating system. A 64-bit operating system can access up to 16 exabytes (or 17.2 billion gigabytes) of RAM.
Which is a better operating system smartphone or android?
Android apps have already beaten Apple iOS quality wise and Sooner, around August android market is going to beat iOS again quantity wise. There would be around 4,25000 apps in android market. So, the thing is it is hard to tell what Android app is best. It basically depends on your on taste as every one has a different criteria of 'BEST APP'.
Usually people go for Professional or gaming apps. I am a android apps Addict and i have huge collection of Android apps. According to me The best professional app is Android Seven Pro which provides windows 7 interface look in your android based device whether its tablet PC or smartphone. If we talk about best android game apps than the fact is mostly people are in to hunting or shooting games like angry birds but you should simply go for Bird Hunting which is the best 2d hunting game and it is one of the most addictive app of android.
If you are not in to hunting games you just look for fun in apps than i would suggest you to try Air Flight Control. This apps is best available free line drawing fun. It is top ranked airplane game of Android.
i hope it works :)
BTW, for the first few steps when you start using your mobile, download and install some great apps will bring you more happiness. I like to enjoy time with audio content. I initially downloaded series of single APP such as BBC, Ted, etc. However, here I actually would like to push CastBox APP in front of you and you can easily get it freely from Google Play. It is a combinated serial podcast that includes diversified FM channels as a radio platform. I really enjoy a good bedtime before sleep and driving way back home with music. From my perspective, I rather recommend CastBox as a great Podcast installed on my phone.
