The biggest difficulty is supporting modern hardware, because the hardware keeps changing, and so the drivers must keep changing, too.
The main difficulty is keeping the operating system within the fixed time constraints of a real-time system. If the system does not complete a task in a certain time frame, it may cause a breakdown of the entire system it is running. Therefore when writing an operating system for a real-time system, the writer must be sure that his scheduling schemes don't allow response time to exceed the time constraint.
First, they have to spend a couple of years with learning the theory and practice of operating systems, and another couple of years with mastering real-time systems.

Types of Operating SystemsWithin the broad family of operating systems, there are generally four types, categorized based on the types of computers they control and the sort of applications they support. The categories are:Real-time operating system (RTOS) - Real-time operating systems are used to control machinery, scientific instruments and industrial systems. An RTOS typically has very little user-interface capability, and no end-user utilities, since the system will be a "sealed box" when delivered for use. A very important part of an RTOS is managing the resources of the computer so that a particular operation executes in precisely the same amount of time, every time it occurs. In a complex machine, having a part move more quickly just because system resources are available may be just as catastrophic as having it not move at all because the system is busy.Single-user, single task - As the name implies, this operating system is designed to manage the computer so that one user can effectively do one thing at a time. The Palm OS for Palm handheld computers is a good example of a modern single-user, single-task operating system.Single-user, multi-tasking - This is the type of operating system most people use on their desktop and laptop computers today. Microsoft's Windows and Apple's MacOS platforms are both examples of operating systems that will let a single user have several programs in operation at the same time. For example, it's entirely possible for a Windows user to be writing a note in a word processor while downloading a file from the Internet while printing the text of an e-mail message.Multi-user - A multi-user operating system allows many different users to take advantage of the computer's resources simultaneously. The operating system must make sure that the requirements of the various users are balanced, and that each of the programs they are using has sufficient and separate resources so that a problem with one user doesn't affect the entire community of users. Unix, VMS and mainframe operating systems, such as MVS, are examples of multi-user operating systems.
The best operating system for PCs all depend on what the PC is mainly used for, such as working, gaming, writing, etc. Each purpose has a different answer.

Technical writing is done to inform and educate people. The author outlines details and operations of scientific, technical, mechanical, or administrative systems so others can use a system. Examples of technical writing include operating manuals for games, computers, or other devices.

You might help a student with writing difficulties by creating worksheets that allow the student to trace letters and words. This creates muscle memory and improves writing skills.
Yes. Most operating systems that ever existed can multitask. Otherwise it would be pointless to use an OS instead of just writing a program.
The World's Writing Systems was created in 1996.
Alphabetic writing systems can be traced back to nature.
