BIOS load the operating system into the computer’s memory and finishes up the boot-up process. The BIOS manages the hard drive but it cannot stay there. BIOS actually stay on the Erasable Programmable Read Only Memory. So it goes…computer powers up, accesses the EPROM and gives complete control to the BIOS. The POST scan checks the hardware and makes sure the processor, RAM, and all other storage devices are all functioning correctly.
Which of the following determines, in part, what bits the computer stores in RAM to represent the number 123456789? The binary equivalent of decimal 123456789 8. Which of the following is not a feature of a file system that might be used with a hard disk drive? An actuator arm 9. A student writes a report using a word processor, saving the report in a file called my_report.
To use federated search, you must download or create XML files for specific sites called search connectors. 5. The only operating system edition that you can upgrade in place to Windows 7 Professional is Windows 7 Ultimate. 6. Upgrading a computer running Windows 7 starter to Windows 7 ultimate using Windows Anytime Upgrade requires------------------ megabytes of additional hard disk space.
Linux is portable, is based on standards, is written in C, has a kernel programming interface, can support many users, and can run multiple tasks simultaneously. The source code for the operating system is readily available so students can understand more easily how Linux works and can modify the code further to understand its operation and to change the way it works. 3. Multiuser operating systems allows the multiple users to access the resources of a single systems at a time or at different time. Allows many users to take advantage of the computer's resources simultaneously.
Linux OS is a derivative of the Unix OS. The Linux OS gain momentum through its progressive licensing which allow others to increase development with the OS. With overwhelming popularity from the creation of Linux OS, Unix OS reintroduce itself again. The functionality of both UNIX and Linux is very similar by both systems able to multitask, both systems are able to run on a variety of hardware platforms, and both are capable to use a command line. Linux is different through user friendly OS and by GUI.
Microsoft offers 2 physical CPUs per license where VM only offers one per CPU. Additional may be bought and stacked if more CPUs are needed. There are some additions that can be paid for, but more everything is include with the platform. VMware offers its platform but every addition there is a licensing fee attached, which is why the company makes additional money. For overall cost, in my opinion Microsoft has the advantage.
Windows has a Virtual memory manager (VMM) and avoids allocating all the memory until it is absolutely necessary. Windows does prefetching, which is moving pages from the disk to the main memory before it is even needed. Pages that are not needed in the memory are stored into a system called Page file until further need. With the Linux operating system, the files are organized already into the hard drive. This will give speed to Linux and provide for faster
Some of the common use of World Wide Web is to gain knowledge in research. When students are doing their home works, instead of going to the library and spending a little more time, they just need to go in front of the computer and search for the topic that they are researching on. Using the internet as a learning resource is somehow more efficient than books when it comes to time. But when it comes to reliability, books are still the best options for us to research since anybody can write, edit, and publish an article on the Web. Internet helped us to communicate with the ones we loved especially those who are far from us.
To flash the BIOS you must the technology known as EEPROM. Then download a copy of the new BIOS firmware from manufacturing and run the BIOS flash installer. IRQ, I/O addresses, Memory addresses, and DMA are the four system resources. IRQ or interrupt request is a communication channel from the hardware device to the CPU. Every device has their own IRQ channel.
When you redistribute the code however, you must also distribute the same license with the code, thereby making the code and the license inseparable. * Linux is an operating system that is put in reach for personal and business computer users. * Linux was born out of UNIX. It was used by researchers as a way to share data and work on projects while still keeping other information private. * Universities
