Pearson BTEC L3 DIT Unit 2 Computer System

The operating systems I will be comparing are Microsoft Windows, Mac and Linux Ubuntu. This will explain about the features between the three operating system about their features and functions. These OS are the most used OS on PCs worldwide and therefore it would be more beneficial to compare the most commonly used. Therefore, these three operating systems also show their strength and also their weaknesses. The Requirements of each Operating systems:  Windows 10 system requirements: Latest OS:  Make sure you're running the latest version—either Windows 7 SP1 or Windows 8.1 Update. Processor:  1 gigahertz (GHz) or faster processor or SoC RAM:  1 gigabyte (GB) for 32-bit or 2 GB for 64-bit Hard disk space:  16 GB for 32-bit OS or 20 GB for 64-bit OS Graphics card:  DirectX 9 or later with WDDM 1.0 driver Display:  800 x 600 Mac OS x system requirements: OS X 10.9 or later 4GB of memory 12.5GB of available st

The functions of operating system and how does it facilitates to the user. (P2) What is Operating System? An operating system is a program on which application programs are executed and acts as a communication bridge (interface) between the user and the computer hardware. The example of Operating system. From Microsoft, Windows 10 Anniversary Update Figure 1: Example of Windows 10 Figure 2: The Windows 10 Logo From Apple Inc. The Apple Mac OSX Mojave. Figure 3 example of Mac OSX Mojave figure 4 the logo from Apple. The Mac OSX Mojave Logo  From Ubuntu, The Ubuntu Linux OS Figure 5 The Ubuntu linux OS Figure 6 The Ubuntu logo The main task an operating system carries out is the allocation of resources and services, such as allocation of: memory, devices, processors and information. The operating system also includes programs to manage these resources, such as a traffic controller, a scheduler, memory management module, I/O programs, a

The Function of computer hardware components (P1)  Task (P1)  Internal System Unit: Processors Definition: A processor is an integrated electronic circuit that make a as a job of it performs that the calculations make a run on a computer. The Functions of the Processor: Fetch:  each of the data instruction are stored in a memory and it has own of the address. The processor will take this number from the address itself then proceed to the program counter, which is make its a responsible for tracking of the data that is stored from the memory which instructions of the CPU should make an execute next. Decode:  All the programs that is process by the CPU will made to be executed and translated into an Assembly instruction. The assembly code must be decoded and breaking the codes into a binary instruction, which is to make understandable to your CPU. (Decoding) Execute: during the executing while making an executing of the instruct
