It superseded their earlier SunOS in This release aims more at the security part and comes with an easy to use application to harden your Desktop.
Mobile OS: A mobile operating system, also called a mobile OS, is an operating system that is specifically designed to run on mobile devices such as mobile phones, smartphones, PDAs, tablet computers and other handheld devices. The mobile operating system is the software platform on top of which other programs, called application programs, can run on mobile devices. Android is unique because Google is actively developing the platform but giving it away for free to hardware manufacturers and phone carriers who want to use Android on their devices.
Symbian OS combines middleware with wireless communications through an integrated mailbox and the integration of Java and PIM functionality agenda and contacts.
The Symbian OS is open for third-party development by independent software vendors, enterprise IT departments, network operators and Symbian OS licensees. There are three Language processors: A. Compiler: It is translator which coverts the HLL language into machine language in one go. Interpreter: It is a translator which converts the HLL language into machine language line by line.
It takes one statement of HLL and converts it into machine code which is immediately executed. However, It is slow in processing as compare to compiler.
Assembler: It translate the assembly language into machine code. Terminologies: Registers: A register is a very small amount of very fast memory that is built into the CPU central processing unit in order to speed up its operations by providing quick access to commonly used values. All data must be represented in a register before it can be processed. For example, if two numbers are to be multiplied, both numbers must be in registers, and the result is also placed in a register.
Bus: A collection of wires through which data is transmitted from one part of a computer to another. You can think of a bus as a highway on which data travels within a computer. When used in reference to personal computers, the term bus usually refers to internal bus.
This is a bus that connects all the internal computer components to the CPU and main memory. All buses consist of two parts — an address bus and a data bus.
The data bus transfers actual data whereas the address bus transfers information about where the data should go. The control bus is used by the CPU to direct and monitor the actions of the other functional areas of the computer. It is used to transmit a variety of individual signals read, write, interrupt, acknowledge, and so forth necessary to control and coordinate the operations of the computer.
The size of a bus, known as its width, is important because it determines how much data can be transmitted at one time. For example, a bit bus can transmit 16 bits of data, whereas a bit bus can transmit 32 bits Clock speed: Also called clock rate, the speed at which a microprocessor executes instructions.
Every computer contains an internal clock that regulates the rate at which instructions are executed and synchronizes all the various computer components. The CPU requires a fixed number of clock ticks or clock cycles to execute each instruction.
The faster the clock, the more instructions the CPU can execute per second. Clock speeds are expressed in megahertz MHz or gigahertz GHz. A bit microprocessor can process data and memory addresses that are represented by 16 bits. A bit microprocessor can process data and memory addresses that are represented by 32 bits. Intel processor, Intel 64 bit Microprocessor: It indicates the width of the registers; a special high-speed storage area within the CPU.
Pentium dual core, core 2 duo. A bit microprocessor can process data and memory addresses that are represented by bits. RISC system has reduced number of instructions.
Performs only basic functions. All HLL support is done in software. All operations are register to register. A large and varied instruction set. Performs basic as well as complex functions. All HLL support is done in Hardware. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. You can change your ad preferences anytime.
