Every device has their own operating system find the best and useful information about OS
1.) What is The Operating system?
An operating system is a software, it allows for communication and easy operation between the hardware and computer software programs.
It helps, both computers and smartphones to performs basic tasks like recognizing any input from the keyboard, being able to store and keep track of files and directories that are on the disk, sending outputs to the display screen, control other attached devices like printers and scanners, basically any external device that can be attached to it.
Every computer that is made for general purpose cannot but have an OS to run every other program and applications as well.
In a basic expression, an OS is a term used to describe software consisting of data and programs and that runs on computer to manage its computer hardware resources and to provide common service for the actions of various pieces of application software.
There would be no exact use for the computer and all of its programs without an OS. It can be compared to the a brain of human being. Without it, the body is basically useless and dead.
Like the name implies, it controls every operation on the computer and equivalent to that; without it, there can really be no operation.
At the time when computers were first introduced, users had just the option of initiating interaction using a command line interface and this required commands for reactions.
Things have changed now as every computer uses a Graphic User Interface (GUI) and it’s a lot more easy to use and to operate.
Mobile devices, DVRs, and even video game systems require an OS to work.
The operating system do the work of telling the computer what to do whenever it goes on, by controlling all the system resources like the memory, the processor, disk spaces and others.
The user doesn’t have to know so much about how the hardware works before he can use the computer, thanks to the OS.
2.) What the operating system does
Storage or memory and management: The OS ensures that every single process possesses enough memory for the execution of the process. Also, ensures that there isn’t a mix up where one process uses the memory that is allocated for another process.
This task must be done in a very efficient manner. In total, a computer possesses four general types of memory.
The list in the order of their speed is as follows: high-speed cache, main memory, secondary memory and disk storage. The OS is packed with the responsibility of balancing the requirements of every process with its compatible memory from the types of memory available.
2.1.) Management of Processor:
For each process and application to run very effectively, as effective as possible, the OS must allocate enough of the processor’s time to each one. This is essential for when the computer has to multitask, engaging in different processes all at once.
For example, at times when so many different applications and software are running at the same time.
2.2.) Management of Device:
This has been briefly explained in the introduction above. Many computers have additional hardware like printers and scanners that are connected to them. And these devices require drivers or special programs for the translation of electrical signals that are sent from the system to the hardware device.
Every input to an output from the computer is managed by the OS.
2.3.) Application interface:
Programmers often use the application program interfaces (APIs) for controlling the computer and also the OS.
The API functions can then be inserted into their programs. The desired action is then taken as the OS encounters these API functions.
As such, the programmer doesn’t necessarily need to have so much detail in controlling the hardware.
2.4.) User interface:
This is a layer that sits just above the OS. It is a part of the created applications through which interaction is initiated by the user with the application. OS use different user interfaces.
For example, the Microsoft Windows and the Apple Mac both use graphical interfaces. Other operating systems like UNIX use shells.
2.5.) Benefits to look for when choosing an operating system
A Computer is only as good as its OS, but when looking to get the best, we need to look for some important benefits.
Thus this checklist was made as a guide to getting to a reliable and stable OS.
Can I easily install it?
Will I able to run all of my favorite software or a reasonable version?
Will it operate on my particular brand of computer?
Are there a fair number of software packages available?
Is it kept up to date to keep up with the ever-changing technology
Is there good support, supports expensive?
Is it reliable, no freezing up?
Is the software itself expensive to purchase?
Are upgrades expensive, how often is it upgraded?
What about spyware and virus software, are they expensive for the system?
Is it easy to learn to use?
Is it easily accessible, can I get it everywhere?
Can I choose how it looks on my computer?
I encourage you to use this checklist when choosing an OS. It is important that you get what you want when you are setting up your computer or resetting it up after some problems.
There is nothing quite as frustrating as spending a lot of time and money to get a good system set up, only to have it mess up or lose your data.
3.) Purpose of the OS for a personal computer
The human body requires a brain to function. It signals the numerous organs within our bodies on how to function properly and interact with each other. With no brain, the human body could not operate at all.
The operating system of a computer similar to the human brain, There are set of the component such as CPU (central processing unit) tower, keyboard, mouse, and monitor, but if no OS installed, its only function is to power on.
The hardware components can’t communicate or share information. It’s the job of the OS to arrange documents and give instructions to various parts of their roles.
While computers were first being developed in the early years, they exist only one operating system
The OS would later be known as MS-DOS and without it, computers were not capable accomplishing many tasks at all.
As a result of this boost from Microsoft, the OS molded personal computers into robust pieces of modern technology that offered considerably more functionality and ease of use.
There are a relatively small number of OS brands that execute many different activities based on the specifications of the PC operator.
Though Microsoft Windows is the most widely used OS today, you will find other breeds of OS that provide various unique options, namely Linux and OS x.
OS is installed in additional devices other than simply computer systems. The majority of the modern day, state-of–the –art cell phones possess their very own OS.
Wireless access points even have their own OS to supply wireless internet services to consumers. As a matter of fact, the processor inside of a cellular phone nowadays has more performance than many of the computers in the past.
Essentially, system software solutions have advanced and continue to evolve. New OS versions and upgrades are constantly being released, which leads computer users of today to speculate whether or not the software program they’re presently running is actually the optimal solution.
It can be a confusing decision when searching for an OS to install on your PC.The choice boils right down to a matter of personal preference.
It will help to be knowledgeable on the features of each OS and establish a complete understanding of what the computer system will be used for.
4.) Types of operating system
Some kind of computers does not require an OS (single-function computers) like the microwave ovens with digital keypads. It’ll mostly be an overkill to try implementing an OS in them.
On the flip side, all personal desktops and laptop computers and servers cannot function without an effective OS.
Although there is so many system software available right now, the very popular ones among users are the Microsoft Windows, the Macintosh and also the UNIX OS.
There are not so many types of OS, in fact, there are just four general types. What determines what OS will be used for a computer is the kind of computer and the kind of applications that will be run on the computer.
Real-time operating systems (RTOS) This kind of system is used in the control of machinery, industrial systems, and scientific instruments. The user of the ROTS doesn’t have so much control over its functions as he or she would with other systems.
Single-user, single-task operating systems: In this type, users are only allowed to do one thing at a time. The OS used by Personal Digital Assistants (PDAs) that is also known as handheld computers, is a very good example of a single-user, single-task OS.
Single-user, multi-tasking operating systems As the name already implies, one user is allowed on this kind of OS to run multiple applications on their computer, all at the same time and also found on personal desktop and laptop computer where users can do different things with different software’s and applications without having to stop one for the other.
Multi-user operating systems This one allows more than one user to at the same time use the same resources on a single computer. A good example of the multi-user OS is UNIX.
4.1.) Linux system software
You may have heard of the term Linux OS – a so-called free alternative to Microsoft Windows or the Macintosh OS.
First of all, Linux is a totally independent entity from Microsoft. The term “Linux” itself is actually unclear, and in fact, is not an equivalent alternative to Microsoft Windows.
You cannot go to the store and purchase a Linux instead you purchase what is known as software distribution of Linux.
Then is the core upon which various distros are built. Thus although you can’t buy “Linux” at the store, you can buy, for instance, the distros Linspire or SUSE Linux. Which are the equivalent alternatives to the windows or Macintosh OS?
There are a ton of different Linux distros. One of the most newbie-friendly (at least to those who are used to Microsoft Windows) distros, which is also hundred- percent free, is called UBUNTU.
You might wonder how in the word something equivalent to windows could possibly be free. Well, in the case of UBUNTU, the answer is, there are some generous software developers out there! You can read more about their philosophy on their site.
Another free distro is the Red Hat, which is more suited to server (i.e. commercial businesses) use. The Red hat actually makes money by charging only for their support.
However, not all Linux distros are free. An example of a commercial (i.e. not free) newbie-friendly distros is Mandriva. If you just want to try out Linux, then most likely you’ll want to go the free route.
UBUNTU is a good choice for beginners wanting to try out Linux. Do not be intimated by the installation process.
UBUNTU is actually highly targeted towards those who are used to Microsoft Windows OS.
As such, the installation process is a breeze, compared to some other Linux distros.
Some HP and Dell computers come with the option of having UBUNTU pre-installed, so you can try buying those if you are sure you do not want to use windows.
5.) How an operating system slows computer processes?
Actually, I believe this method would work but I know there is an easier way. Before I get into this easier way, let talk about two ways a system software can slow down a PC. They are:
Upgrading to the OS with an older PC and, having registry corruption build up in the operating system’s registry.
Of course, the first problem can only occur if you have changed the OS on your PC or upgraded to a newer one.
The fact of the matter is each window operating system is larger than its predecessor and so the computer ends up with less free resources then it had when the old OS was running it. Fewer resources equal a slower computer, simple.
Future of the operating system
In the future, operating system and information management are sure to go from the general less informative to the particular very detailed level? OS of today are somehow upside-down due to the way at which they developed; the hard way that gradually pulled and struggled upwards from the machinery (processors, memory, displays, and disks) towards the user.
All the features of a computer and computing experience should make life a lot easier and not weigh you down. It’s supposed to help you unify your online experience and unify all your important information rather than have too many channels and sections for information to easily get lost and hard to find.
It should a lot easier to compile all documents and files and every necessary detail and easily find them and know where they are. and also easier to manage external devices and still have file security, and so many other things that an OS should embody in this day and age.
But considering the rapid growth of the OS and computer market over the last decade.
there is an assurance that all these holes will be filled and our computing experiences will be a lot better.
The OS of the future will be an orchestration system that will put together and coordinate every of your computing assets no matter where it is on the system.
We can see a future with a virtual machine that will keep alive your computing experiences and provide results regardless of where it physically occurs.
What this means is that it’ll be easy to track and manage all assets from anywhere and still derive the same results as opposed to now that everything is confined to be a single machine.
If you think a little deeper about what an OS does, it’s kind of a glue system that puts together all your computing resources and runs the applications without necessarily thinking of the underlying resources.
Operating systems in the future will have more sauce (permit me to use that). It’ll be very distance friendly whereby so many things can open from one source (computer) and reflect on another source.
Personal user assistants have been created like the Crotona for the Windows and Siri for the Mac OS that makes easy the user experience. It’s like have a personal human assistant but this being virtual
The growth and improvement of the OS (all the types available) have been on the high side and has gotten easier and more reliable over the years.
The future of OS will provide greater experiences with new and easier ways to manage files operate and personalize use.
