The Language of IT Consultants

Imagine your business computers and network are broken. Your staff is sitting around NOT Working and your on the phone with a tech support person born and raised in India for whom English is NOT their first language. The nature of the conversation covers the infomation below… That’s because your operating system is not talking with your printer. Good Luck! We speak English and come to your site to make things work…

An operating system (OS) is a set of programs that manage the software and hardware components of a computer. The OS controls the computer(or other electronic device) by processing requests approved by the system. It is the foundation of all system software and performs the basic tasks of controlling and allocating memory, prioritizing system requests, controlling input and output devices, facilitating the network and managing files. For interface with higher functions, the OS can provide a graphical user interface(GUI).

Basically the OS is a platform for other system and application software. The most important software or program on a computer is the OS. A computer will not work without an operating system, it is the brain of the computer. In a larger computer the OS has greater, more responsible duties. It works like a traffic cop in larger computers and systems. It enables different users and multiple programs to work at the same time without interfering with each other. It also keeps unauthorized users from accessing the system.

There are several classifications of a computer operating system:

Multi-User: Allows two or more users to run programs at the same time. There are operating systems that will allow thousands of users at the same time.

Multi-Processing: Let’s you run a program on more than one central processing unit.

Multi-Tasking: Allows more than one program to run at the same time.

Multi-Threading: Allows the different parts of a single computer program to run at the same time.

Real Time: Responds instantly to input. General-purpose operating systems, such as DOS and UNIX, are not real-time.

Application programs, like notepads or accounting programs, run on top of the software platform that an operating system provides. An application program is specifically written to run with a particular operating system. Not all application run with all operating systems. So your choice of operating system will determine the applications you can run. Most PCs run on Windows, DOS of OS/2. Linux is also used, but not as popular. There’s a way to make changes to how a device works with any operating system. Operating systems are made of portable code not physical circuits so that changes and updates can be made easily and cost efficiently. Rather than replacing the whole unit.

The majority of computer users can add a security update, a system patch, a new application or program or even a new OS completely, rather than starting over with a brand new computer each time you needed a change. In many cases you can change the way the OS behaves if you understand it and know how to get to it. That’s true for your cell phone and your computer. The first program, when you turn on your computer, is a set of instructions that are kept in the computer’s read only memory(ROM).The system hardware is examined by these instructions to make sure everything is working properly. It checks the central processing unit(CPU), the memory and the basic input/output systems(BIOS) for errors and stores the results in a special memory locations when you power up the computer. When the test has successfully completed, the computer’s disk drives will be activated by the software loaded in ROM (sometimes called firmware or BIOS).

The bootstrap loader is the first piece of the operating system that the computer activates on the hard disk drive. It is a small program with only one function, to load the OS into memory and begin operation. The bootstrap loader sets up the small driver programs that interface and control the different hardware of the computer. It divides the memory into the OS, user information and applications. It builds the data structures that will hold many signals, flags and semaphores. These are used to communicate with and between the applications and subsystems of the computer. When that is complete, it turns control of the computer over to the OS.

When your computer network is not communicating, let’s not compound the problem with calling India.. Call Tranquilnet, Inc…
