Operating Systems

To run a program without an operating system is a really difficult task. If one needs to type a document in a word processing program, one will have to create a code that will tell the computer to respond to each character pressed on the keyboard. Then one will have to write a code to tell the computer how responses must translate to the screen.

Some advantages Windows has is its more familiar to people and thus considered the mos "user friendly." Its monopoly on the desktop tends to mean that just about any tech support professionals will be most familiar with it. If you're a gamer its got the best and the most PC games made by professionals.

Disadvantages: It's slow, bloated, inefficient, has poor memory management, very insecure, tends to be unstable. It is proprietary, meaning only Microsoft can actually improve it in the ways that matter, and they've demonstrated no interest in doing so for the longest time. It is also not very flexible and scalable at all. Because of this, its a poor choice for most applications, even on the desktop, but its support for things such as servers, mobile, and embedded are a nightmare. It's nonexistent on supercomputers or robotics, and on extremely mission-critical applications, it is frequently passed over for Linux. Things such as the military, stock market, and healthcare industry especially make a policy of avoiding Windows on anything crucial to their operations and tend to use Linux instead due to Windows being unreliable at the best of times. It is also the most expensive operating system in the market by far.

Linux Advantages: It's the third most common operating system in the world, and it is also the fastest growing. This makes it familiar to a growing amount of people. Linux actually has the widest hardware, software, platform, and tech support base of any operating system in computer science history, and can even be installed on things many people would never consider: Xbox, Wii, PS3, Palm Pilots, even Microwave ovens and toasters! Its two top desktop environments (GNOME and KDE) are actually what make Linux better in a lot of ways than Windows on the desktop. Not the least of which is giving the user far more choice and flexibility while still retaining "user friendliness." Out of the box, it supports far more hardware than Windows does out of the box. Outside of the desktop, Linux is very strong and very dominant, especially in the server, embedded, and supercomputer markets, a testament to its security and power. Speaking of which, it is the exact opposite of Windows when it comes to size, efficiency, security, and reliability. In another 5-10 years, Linux will probably have the absolute best hardware support in every category as hardware manufacturers learn that they can support Linux for next to no cost in just a few ways: 1. They can just release specs and let the open source community make their drivers for them, which won't actually cost them a dime. 2. They can hire just a couple developers for open source drivers, and still have a massive developer base around their driver as the rest f the community pitches in. 3. They can just leave it well enough alone and allow the Linux developers reverse engineer the hardware. This is not the best way for Linx developers as its a decidedly uncooperative approach taken by many hardware manufacturers. 4. They can just make a small department dedicated full-time to Linux drivers, usually binary blobs. This is nVidia's approach. Sometimes proprietary drivers support hardware very well in Linux, sometimes not. You will get tech support from a much more helpful and reliable place: The entire Linux community. Almost all the Linux distributions are free of charge, and those that are commercialized never cost more than $50. And their commercial tech support, whenever you can actually have it, is usually far more effective and helpful than the typical commercial Windows tech support. Also, if you runa business, a Linux-based infrastructure is the best. It's, reliable, secure, and if you have the money, you have IBM in your corner giving you the best business infrastructure support and consulting money can buy.

Linux Disadvantages: It is not a strong gaming environment. Not for a lack of technology, but just a lack of general developer interest. Also, though it has a lot more support for hardware than Windows, often (But not usually) the individual support for hardware can be missing parts. This can't really be blamed on Linux but, again, a lack of manufacturer interest in the platform. It wasn't until about 5 years ago anyone took Linux seriously as a desktop option (It always has been a strong, preferred server option, however.). Currently some hardware manufacturers completely ignore Linux even after it has proven desktop viable. This typically won't stop drivers from coming around, but it means that the driver might take a long time as the developers are forced to reverse engineer the hardware. Due to Windows monopoly and desktop PCs almost always being designed around Windows, you're not likely to get anything useful from tech support if you use Linux. This isn't too big a disadvantage as most professional tech support actually does operate on a corporate agenda and will try to enforce a status quo on you.

If you ask my opinion, unless you want to game hard on this machine, go Linux exclusively, there's nothing Windows will offer you that Linux doesn't provide better cheaper(If not entirely free.). If you plan to do anything else, Linux is the best option. Servers love it, so do supercomputers. And now, with Android, cell phones use it, too.

When computer runs out of RAM, it starts swapping things on your hard disk. So, your HDD acts as a virtual memory. But it is a slow process. You can use USB flash drive too as it is much faster.

it's consist of big system and that system we sub divided into sub systysem called a distrbuited system.

an example of this is a scada system that have one main control system and through that system we distrbute the system to the site that we have which called a distrbuted system .

every computer has a central processing unit or CPU in it to perform a specific task.

a CPU contains: datat processing unit and control unit.

the Data Processing Unit consists of Airthmatic logical unit and some registers and the control unit consist of some hardware and software to generate a control signal .

whenever we want to perform some specific task we give computer an instruction or set of instructions called program. the definition of these instructions is stored in the memory of computer. these instruction are processed in a cyecel containing mainly three steps:

1.instruction fetch(taking instruction from memory)

2.instruction decode(understanding the meaning of an instruction)

3.instruction execution(performing the task0

each of above given step contains one or more steps further and these steps are called "microoperationS".

on execution of instruction the specified task is done..

It is a true statement to say that scheduling is an important component to the success of a business. Scheduling can include ordering equipment, supplies, or creating a work schedule for employees.

The modular kernel approach requires subsystems to interact with each other through carefully constructed interfaces that are typically narrow (in terms of the functionality that is exposed to external modules). The layered kernel approach is similar in that respect. How- ever, the layered kernel imposes a strict ordering of subsystems such that subsystems at the lower layers are not allowed to invoke operations corresponding to the upper-layer subsystems. There are no such restrictions in the modular-kernel approach, wherein modules are free to invoke each other without any constraints.

In an operating system, links are established through various mechanisms depending on the context. For file systems, links can be created using symbolic or hard links, which point to the inode of a file or directory, enabling multiple paths to access the same data. In networking, links are established through protocols that manage connections between devices, often using IP addresses and ports. Additionally, process communication can involve links via inter-process communication (IPC) methods such as pipes, message queues, or shared memory.

an operating system is capable of allowing multiple software processors to run at the same time

As computers have progressed and developed so have the types of operating systems . Therefore there is an infinite number of "types", depending on the way of classifying. For ex: Free or proprietary? Real-time? Unix-like? 16, 32, or 64-bit? Server, desktop, or embedded? By kernel type? To answer your question the classification should be clearly stated. But I hope the following would guide you close.

Within the broad family of operating systems, basically they can be categorized based on the types of computers they control and the sort of applications they support.

The categories are: Real Time OS, Single user single task, single user multi tasking, multi tasking. (or multi user, multi processing, multi tasking, multi threading)

Many computer operating systems will fall into more than one of the above categories.

Go to controll panel. Open Folder Options. Click File types tab Select JPEG Click advanced and then click Change Icon Button....Now u can find icons u were looking for !!.....
But remember one thing/......Your system may stop responding while viewing the file types.........This is the Pbm of windows

Go to the webpage and right click then choose "create shortcut".

For a Windows computer, right click on the mouse and a menu pops up and click on create shortcut. A window will pop up that says "a short-cut to the current page will be placed on your desktop" click on "ok".

Yes you can! To do it, you need to download a program called Oceanis.

After you download it, install the program. Then you will have to restart your computer. When you open the program, it will ask you to browse for a folder with pictures. Select a folder and then choose the pictures that you want to have on your desktop.

If you choose more than one picture, your computer will play the pictures as a slide show on your desktop. However if you only choose 1 picture, your computer will only show that 1 picture. I personally like having only one picture because it saves battery life and doesn't slow down you computer. This program also has no Viruses, Trojans, or Spyware!

Global System for Mobile Communications, or GSM, originally described a digital circuit switched network using full duplex voice telephony. It has been upgraded to include data communications and packet transport.

A microcomputer can have core capabilities or functions. The first abilities are the related computation and storage of data. The second core is being able to access, then convert to out signals for display, and the transmittance of data across networks. A microcomputer by definition can take and execute the instructions of its programs and operator also.
