Operating system
Now we are going to
explain the basics of OS.This is an interface between a computer user and
hardware.It is very important as it works as a middleman making sure both
hardware and sogtware.Correctly there are 4 essential managers of every OS and they
all coork together like team to get jobs completed.
First, Memory managment
is the function that controlling and coordinating memory location and either
allowsted or free blocks to varoius programms to optimize overall system
perpormance.These are 4 types of technique ways to manage memory
1. Single configous allocation.
2. Partiction allocation
3. Paged memory management
4. Segmented memory management
all this techniques has their own advantages on their own.
In hardware memory management involves components that physically store data
such as RAM(Random access Memory ), VRAM(Virtual Random Access Memory),
GRAM(Graphic Random Access Memory) chips, memory caches and flash based
SSPs(Sold Store drives)
Next.The basic unit of
software that the operating system with in scheduling work done by the
processor is either a process or a thread depending on the OS.It is processes
rather than applications to begin running suspending the execution only long
enough to deal with the interrupts and user input. Process management is an
integral port of any modern-day operating system the OS must allocate resources
to processes enable processes to share and exchange information protect the
resources of each process from the processes and enable synchronization among
process.To meet these requirements the OS must mountain the data .Structure for
each process, which describes the state and resource owner ship of that process
and which enables the OS to exert control over each process.
After that Device manager
is Control Panel applet in Microsoft Windows operating system. It allows user
to view and control the hardware attached to the computer.Hardware devices
typically provide the ability to input data into the computer output data from
the computer Device management
does the following activities for device manager keep track
of all devices, decides.this process gets the device.allocates the devices in
the efficent way de-allocated devices.Device manager important to make sure.
It's well designed.
Device drivers
Device detection
asynchronous I/O
Power managment
Userspace exposure
Exciting driver interface
Next. A file manager or
file file browser is a computer programm that provides a user interface to
manage files and folders.It has limited capalities and is designed to manage
individual or group files such as special office documents and records.File
managment describes the fundamental methods for meming storming and handling
files.by using appropriate file and folder making strategies along with good
practice and catalog software.You can make the most of your image collection.
Finally. An OS is simple
term. It's the chief program that manager all of the hardware and software,It;s
coocks as their bass and makes sure they all working in harmony.
