Abstract

This paper will elaborate on the major differences of the main Operating Systems (OS), which are UNIX/Linux, Mac®, Microsoft® Windows®. The areas of discussion for this paper will be on Memory Management, Process Management, File Management, and Security for each operating system. Operating Systems (OS) for a computer is the main processing software program used to allow the computer processor to communicate with the software and hardware I/O devices. Computers as SUN, SUSE use UNIX/Linux operating system, Mac® (Macintosh) computer uses Apple operating system, and Personal Computers (PC) and most business computers use Windows® Microsoft® operating systems.

Operating System

Computers as SUN, SUSE use UNIX/Linux operating system, Mac® (Macintosh) computer uses Apple operating system, and Personal Computers (PC) and most business computers use Windows® Microsoft® operating systems. Each operating system is a multi-user system, multiprocessing, multitasking, and multithreading. An operating system capable of allowing multiple software processes to run at the same time is a multiprocessing and multitasking computer. Operating systems that allow different parts of a software program to run concurrently are considered multithreading. Computer processing uses memory for instructions and subroutines. The use of memory and managing is not simply just reading and writing to the computer. Each computer memory in the system uses it differently. Memory Management is a vital part of the processing of data. Virtual, cache, processor, data, direct access, random access, single in-line memory (SIMM) are types of memory used in a computer system. Processor speed is dependent on memory management, which allows the use and operation of the computers.

    While in the hardware, memory management includes elements that store data such as random access memory chips, and memory caches. In the operating system, memory management involves the distribution of precise memory blocks to programs as the user requests adjustments. While at the application and program level, memory management ensures the availability of sufficient memory for the objects and data structures at all times for each program that is running.…

    Random-access-memory (RAM) is a very important specification of the computer. By ensuring you have enough RAM, the faster your system processes, you can store more data, and allow more programs to run at the same time. As the OS allows the different task to complete for the processor, the RAM is used as temp storage, when the processor no longer needs them the OS clears it. Virtual memory is the hard drive space borrowed to use if there isn’t enough…

    Operating systems were not in existence before the 1960s. The definition of operating systems is a program designed to run other programs on the computer and is the most important program. In the past, computers were built to execute a series of single task similar to a calculator. In the 1960s came the MCP (Master Control Program) for the B5000 mainframe computer created by the company Burroughs/Unisys. The MCP was the first OS written exclusively in a high-level language. As the years progressed, OS giants were starting to form such as Windows, Linux, and Mac. In, this paper, these 3 tech OS giants will be examined thoroughly while covering memory management, process management, file management, and security.…

    Linux: the Operating System You Should Choose

    There are quite a few operating systems are being widely used. With 92% of the OS market share, Windows OS is dominating the OS market. Macintosh, the operating system only works on Apple computers, occupies 7% of the total share. Linux, the last widely used OS, has only 1% of the share now. The most difference between Linux and other operating systems is that Linux is an open-sourced OS, which means everyone has access to the source code of this OS. People can modify and use the source codes of it without charging. Linux According to the research done by NETMARCKETSHARE (2012), Linux’s share has grown from 0.97% in July, 2011 to 1.41%, Oct, 2012. The reason of Linux’s share increase cannot be understand without explaining in which aspects Linux are working better than other operating systems. In this essay, the advantages and disadvantages of Linux will be discussed and it will specifically investigate the cost of adapting to Linux, the performance of Linux and the support of Linux.…

    Cache Coherence

    Computer memory is organized into a hierarchy. At the highest level (closest to the processor) are the processor registers. Next comes one or more levels of cache. When multiple levels are used, they are denoted L1, L2, etc… Next comes main memory, which is usually made out of a dynamic random-access memory (DRAM). All of these are considered internal to the computer system.…

    Types of Operating System

    Multi-tasking and Single-tasking Operating Systems: When a single program is allowed to run at a time, the system is grouped under a single-tasking system, while in case the operating system allows the execution of multiple tasks at one time, it is classified as a multi-tasking operating system. Multi-tasking can be of two types namely, pre-emptive or co-operative. In pre-emptive multitasking, the operating system slices the CPU time and dedicates one slot to each of the programs. Unix-like operating systems such as Solaris and Linux support pre-emptive multitasking. If you are aware of the multi-threading terminology, you can consider this type of multi-tasking as similar to…
