   • Operating System - Difference Between Distributed System and Parallel System

     A distributed system is a model where distributed applications are running on multiple computers linked by a communications network. Sometimes it is also called loosely coupled systems because in which each processor has its own local memory and processing units. LOCUS and MICROS are some examples of distributed operating systems.

     Parallel Systems are designed to speed up the execution of programs by dividing the programs into multiple fragments and processing these fragments at the same time. Flynn has classified computer systems into four types based on parallelism in the instructions and in the data streams. 

     • Single Instruction stream, single data stream
     • Single Instruction stream, multiple data stream
     • Multiple Instruction stream, single data stream
     • Multiple Instruction stream, multiple data stream

     Advantages of Distributed Systems:

     • Scalability: Distributed systems can be easily scaled by adding more computers to the network.

   • Operating system file system block size?

     Top Answer

     Answered Nov 21, 2013 · 1 votes

     You can't have a big amount of different block sizes, that would be hell to implement and manage. I also think that some hardware limitations restrain what sizes you can use.

     Now the thing is, unless the amount of data you wish to store fits exactly in all the blocks you are using, then some space is going to be wasted in the last block.

     For example, if your block is one gygabyte long (hypothetically speaking), and you want to store a 1 or 2 bytes long file, you've just wasted nearly a gigabyte of disk space. All information is stored as blocks. You can't store half a block.

     Long blocks make for better performance, though, since the disk may spend more time fetching information from a block before proceeding to the next one. Also it's less blocks to track and manage.

     Linux is a fun operating system to play with because it can work with so many different file systems (as far as I remember you only get some variations of FAT and NTFS with Windows). You could read more about file system on this link:

     Linux System Administrators Guide: Chapter 5. Using Disks and Other Storage Media

     See section 5.10.5 for more info on advantages and disadvantages of small and big block sizes.

     So back to your question: having different block sizes like that allows you to optimize storage. You can minimize wasted space by switching to smaller blocks by the end of the file, while having as few blocks as possible to reduce I/O times.

   • What is a Mobile Operating System?

     Mobile ope­rating systems (Mobile OS) manage mobile­ gadgets like phones and table­ts. These systems run apps. The­y are not like desktops as mobile­s have different ne­eds. An operating syste­m (OS) for mobile devices manage­s the basic functions. It runs apps, controls memory, and connects to ne­tworks. These systems provide­ an easy-to-use interface­.

     They’re designe­d for smartphones, tablets, and wearable­ tech. Mobile OSes le­t you multitask, browse the web and download apps. Popular options include­ iOS from Apple, Android from Google, and Huawei’s HarmonyOS. Mobile­ operating systems power mode­rn gadgets. With them, phones be­come portable computers, communication tools, and e­ntertainment hubs.

     Key Feature­s of a Mobile Operating System

     1. User Interface (UI): Touch inputs of Graphical User Interface (GUI) provided by mobile OS are optimized. This is where users can use touch gestures, in other words, swiping, tapping, and pinching, to interact with their gadgets.

     2. Multitasking: It helps in running of many apps at the same time but what is more we can quickly switch between them without any hindrance. Such offloading is for applications that are not currently used actively.

     3. Connectivity: It provides a...
