#Disadvantages Of Serial Processing Operating System software

Monitor: a software program that handle executing the jobs provided by the user on tapes or disks.Users have access to computer in series.Setup time: A single program called a job had to be installed before used with its compiler and code, saving the object program and linking and so on to run the program.Scheduling: users had to sign-up sheet to reserve computer time, users couldnвЂ™t`t know precisely how long it will take to finish their program.This systems presented two main problems.

In the dark ages, when there was no OS from late 1940s to mid-1950s (I call this years: before OS, abbreviated BOS like BC) the programmer had to deal directly with the computer hardware, These computers were run from a console consisting of display lights, toggle switches, some form of input device. Bug Fixes: Bugs appear over time, and detected by users, so OS should be fixed for this bugs, and sometimes fixing a bug raise another bug.New services: OS offers new services demanded by the users or system managers.Hardware upgrades and new types of hardware: New types of hardware require that the OS be able to deal with it, so OS should be built with support for that hardware.The processor operation itself is controlled by the OS, that OS decides how much time the processor can spend on a particular program.The OS decides when I/O device can be used by a program in execution.Memory allocation is controlled by the OS and the MMU (Memory Management Unit).

Accounting: monitoring system resources and collect usage statistics, help in judging whether to upgrade the resources or it is efficient enough.

Error detection and response: detect program and hardware errors so as to clear the error condition with the least impact on the running applications.

System access: protect system data and resources from unauthorized users.Controlled access to files: provide protection mechanism to control access to files.Access to I/O devices: act as a faГ§ade to I/O devices.Program execution: automate a number of steps to execute a program.Program development: editors, debuggers they are tools supplied with the OS.

OS provides a variety of services in the following areas:.

Ability to evolve allow for further development to allow to system functions.

Efficiency allows us to use computer resources in an efficient manner.

Convenience makes computer more convenient to use.

A program that controls the execution of application programs, and act as an interface between the application and the computer hardware.

Now as a computer science student, I figured out what Operating System вЂ“ abbreviated OS вЂ“ is all about, this article intend to give a brief overview to Operating Systems.

2000 was the year I convinced my father to buy a computer at home, Some guy came at home and installed Windows so that we can deal with the computer, This Windows was like a mysterious thing or like a ghost that controls my PC, Actually I didnвЂ™t pay attention to know what Windows is all about rather than it is a kind of вЂњOperating SystemвЂќ ! but as an end-user I was very good at using it. You can also choose from high productivity, high safety level, and energy saving hemp decorticator, as well as from egypt hemp decorticator, and whether hemp decorticator is manufacturing plant, farms, or hotels.I dealt with computers first when I was in the elementary school around 1998, where I used to play Sky Roads on DOS computers.

A wide variety of hemp decorticator options are available to you, such as new.

Those variables are six levels of moisture content of the nuts (3%, 6%, 9%, 12%, 15%, and 18% d.b.), three levels of the roller speed (400, 450, and 500 rpm), and three levels of clearance between the roller and.

To have desired outcomes, the performance of the decorticator was evaluated at 54 different combinations of independent variables.

It is full-automatic, very low labor cost, high capacity, and high quality It is really perfect for industrial producing Other features: 1.

Automatic Natural Fiber Processing Machine/ Sisal Jute Hemp Pineapple Leaf Decorticator/ Banana Fiber extracting Machine is the one we have the most repeat customers.
