Operating Systems

The user view of the computer varies by the interface being used. Most computer users sit in front of a PC, consisting of a monitor, keyboard, mouse and system unit. Such a system is designed for one user to monopolize its resources, to maximize the work that the user is performing. In this case, the operating system is designed mostly for ease of use, with some attention paid to performance, and none paid to resource utilization.

Some users sit at a terminal connected to a mainframe or minicomputer. Other users are accessing the same computer through other terminals. These users share resources and may exchange information. The operating system is designed to maximize resource utilization.

Other users sit at workstations, connected to networks of other workstations and servers. These users have dedicated resources at their disposal, but they also share resources such as networking and servers.

Recently, many varieties of handheld computers have come into fashion. These devices are mostly standalone, used singly by individual users. Some are connected to networks, either directly by wire or through wireless modems. Due to power and interface limitations they perform relatively few remote operations. These operating systems are designed mostly for individual usability, but performance per amount of battery life is important as well.

System software is a software which provides a platform for running application software(s).

examples of system software are Linkers, Loaders, Operating Systems,compilers,database systems and editors.

Embedded software is a special type of software which are designed for special purpose (usually with negligible user interaction ) e.g.automobile software, software used in air conditioning system.

According to ComputerWorld.com (http://www.computerworld.com/s/article/9121938/Windows_market_share_dives_below_90_for_first_time), Microsoft Windows has 90%, Mac has 9%, and Linux has 1%.

An example of Single task, single user Operating system is Palm OS for palm handheld computers.

If the software is kept up to date, and a firewall and anti-virus software is being used, then there are really no vulnerabilities. Unless the user takes risks with downloading unknown files; or opening unknown attachments on e-mails.

discuss the difference function of an operating system

The MVS operating system was the most commonly used operating system used on mainframe computers. The MVS operating system was developed by IBM and was first released in 1974.

There are a few places one can find a time and attendance systems. Check out office supply stores for basic systems, or a site such as timeclockdepot for more advanced systems.

UNIX.

The allocator places a process in the smallest block of unallocated memory in which it will fit.

A semiphore is a means of protecting a resource/data shared between threads. It is a token based mechanism for controlling when a thread can have access to the resource/data.
Usually a semiphore handle will be able to be received from the system by name/id.

See Also Mutex. which is a simplification of the semiphore concept.

Operating systems (OS) are the software that manage a computer. Windows is an operating system; so are Linux, Unix, MAC, etc. Programming languages, like C, C++, etc., are used to write the program coding. Open source is referring to software that can be shared and run on multiple operating systems.

Windows 95

The operating system OpenWrt is a Linux distribution used on embedded systems that route network traffic such as home routers. It can be configured via a command line or web interface.

Apple computers have a very suitable operating system for multimedia development. That company have been developers of various formats in the multimedia field.

lMultithreading an interactive application may allow a program to continue running even if part of it is blocked. For instance, a multithreaded web browser could still allow user interaction in one thread while an image was being loaded in another thread.

Systems software is a any program that lets you interact with the kernel (the one that talks with hardware ) to perform useful tasks. Examples include text editors, compilers, assemblers, operating systems.

An interface is a device that interpretates data. A port is only the door in and out from the computer.
