In many respects an operating system works like an air traffic controller to coordinate activities within the computer. This includes controlling functions such as the coordination of the hardware and applications software, allocating storage facilities, controlling the input and output devices and managing time sharing for linked or networked computers.

Every general-purpose computer must have an operating system in order to run other programs. The most important program that runs on a computer is the operating system. Systems softwareincludes the operating system and all the utilities that enable thecomputer to function. There are two kinds of software, systems software and applications software.

User friendly: Computer software or hardware that issimple to set up, run and use. This is because the software being used today is written in a highly user-friendly manner and in a way that does not require knowledge of the computer languages which were used to create and use it. Please note: most people who use computers today do not need to worry about programming, machine, or assembly languages. Assembly languages have the same structure and set of commands as machine languages but they enable a program to use names instead of numbers. Lying between programming languages and machine languages are assembly languages.

This language is used by the computer to understand the programming language and translate the terms into executable instructions. The language the computer actually understands is called machine language, which comprises numbers only. Each language has a unique set of words (codes) that it understands and a special syntax for organising program instructions. Over the years, a wide range of programming languages have been developed, including BASIC, FORTRAN, PASCAL, C++, JAVA, and so on. Programming language: An artificial set of rules,vocabulary and syntax used to instruct the computer to execute certain tasks.Ĭomputer program: A sequence of instructions thatcan be executed by a computer to carry out a process. Without a program, a computer is useless. That is, the instructions need to be written in a programming language that the computer can understand. For software (the instructions) to perform various functions, it must be programmed. In addition, the solution cannot be overridden by children because it is controlled from the Safe Eyes website with password-protected setup.Software is the computerised instructions that operate the computer, execute particular functions or tasks, and manipulate the data. Safe Eyes Mobile has no noticeable effect on iPhone performance. Safe Eyes Mobile filtering works on both the AT&T cellular network and individual Wi-Fi networks to which the iPhone automatically connects when in range. In contrast, the iPhone itself can control Internet browsing only by blocking Web access entirely, while AT&T’s wireless MEdia Net Parental Controls do not work on the iPhone at all. Parents can also configure the software to filter sites in 31 other categories as well as by URL. It prevents iPhone/iTouch access to pages in the pornography, nudity, sex and tasteless/gross categories by default. Safe Eyes Mobile works by checking requested websites against a massive blacklist of potentially objectionable Web addresses that is updated on a daily basis.

This new browser for the iPhone, iPhone 3G and iPod touch blocks millions of pages of inappropriate online content while allowing full access to the rest of the Web, eliminating the need to turn off the iPhone’s highly acclaimed mobile browsing feature to avoid exposing children to the unsavory side of the Internet.
