The proper sequence of actions in a machine cycle is?

The proper sequence of actions in a machine cycle typically includes fetch, decode, execute, and writeback. During fetch, the CPU retrieves instructions from memory. In decode, the CPU translates the instructions into signals the computer can understand. The execute stage involves actually carrying out the instruction, and writeback stores the result back into memory if needed.

Does ext3 provide journaling in Linux?

Yes,ext3 provide journaling in linux. there are 3 types of journaling provided by ext3 1) Journal-full journal mode,all data can be recovered. 2) Writeback-it only recover metadata(data about data),corrupted file can not be stored. 3) Ordered-recover metadata and specific file data.

What are the different phases of instruction cycle?

The instruction cycle consists of fetch, decode, execute, and writeback phases. In the fetch phase, the instruction is fetched from memory. In the decode phase, the instruction is decoded to determine the operation to be performed. In the execute phase, the operation is carried out. Finally, in the writeback phase, the results of the operation are written back to memory or registers.

What is the differences between ext2 ext3 and ext4 file system in Linux?

Ext3 is a tiny bit slower than ext2 is, but it holds tremendous advantages. There is really only one difference between ext2 and ext3, and that is that ext3 uses a journal to prevent filesystem corruption in the case of an unclean shutdown (ie. before the filesystem is synced to disk). That makes ext3 a bit slower than ext2 since all metadata changes are written to the journal, and then flushed to disk, but on the other hand you don't risk having the entire filesystem destroyed at power failure or if an unwitted person turns the computer off uncleanly. You don't have to check the filesystem after an unclean shutdown either. Ext3 has three levels of journalling. Metadata (ie. internal filesystem structures) are always journalled, so that the filesystem itself is never corrupted. How ordinary data is written to the file system is controllable, though. The default option is the "ordered" mode, which causes file contents to be written to the filesystem before metadata is even committed to the journal. The highest reliable mode is called the "journal" mode, which causes file data to be committed to the journal before it is flushed to its final place, like the metadata. The least reliable mode, but rumoured to be the fastest, is called the "writeback" mode, which makes no promises at all regarding the consistency of file data. Only metadata is output reliably in writeback mode. So as for anything else, it's mainly a matter of priority. If you don't want ultimate speed, go with ext3. If you need the highest speed that is theoratically aquirable though, then go with ext2. For that to be effective you'll probably need a really advanced hard drive controller, though.

What is the CPU and its importance to a computer system?

The CPU (Central Processing Unit) is the 'brain' of the computer so to speak. It handles all the arithmetic and calculations of the computer. Everytime the computer executes an action, it runs through the CPU before writing any results to storage. Without a CPU a computer can not function. This is a very simple explanation however, there is more detailed information out there that covers the ALU circuit and other things.The CPU (Central Processing Unit) is the 'brain' of the computer so to speak.

What is function of central processing unit?

CPU stands for central processing unit. Overall a personal computer can be divided into the following major parts from point of view of functions performed: 1. Input devices (keyboard, mouse) 2. Output devices (monitor which displays the output or results of work being done on the computer) 3. CPU (central processing unit, which is the brain of the computer which does all the processing and calculations on data inputs and provides output on screen or printer) 4. Storage devices (memories, hard disk which store data). Many times in common language the CPU term is used for the computer box unit which contains motherboard, processor, hard disk, CD/DVD and floppy drives. This is the box to which we connect monitor, keyboard, mouse and printer through cables. In technical terms the term CPU is used only for the processor, which fits on the motherboard.

What are examples of hardware on a computer?

Three examples of personal computer hardware would be a Hard Drive, a CD Drive, and a monitor. There are lots of other hardware components as well, such as RAM modules, motherboards, and processors. Some hardware lies within the machine, while other components, like the monitor and keyboard, are outside the PC case.
