Computer Hardware: Hardware Components and Internal PC Connections. / www/public/us/en/documents/product-briefs/reffirodonverm.tk Hardware: Computer hardware is the collection of physical elements that constitutes a computer system. Computer hardware refers to the physical parts or . computer hardware and the importance of keeping your computer and its data safe. Next Finally, you learn about applications software and how a computer.

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.

What is Computer?

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. Memory to memory addressing mode EPIC Explicitly Parallel Instruction Computing : It is a bit microprocessor instruction set, jointly defined and designed by Hewlett Packard and Intel, that provides up to general and floating point unit registers and uses speculative loading, predication, and explicit parallelism to accomplish its computing tasks.

By comparison, current bit CISC and RISC microprocessor architectures depend on bit registers, branch prediction, memory latency, and implicit parallelism, which are considered a less efficient approach in micro architecture design. Typically on older PCs, a modem, mouse, or keyboard would be connected via serial ports.

Serial cables are cheaper to make than parallel cables and easier to shield from interference. It is also called communication port. It provides much higher data transfer speed in comparison with serial port. It is also called Line Printer Port. USB is also much smarter and more versatile since it allows the "daisy chaining" of up to USB peripherals connected to one port.

The interface is comparable with USB and often those two technologies are considered together, though USB has more market share. Infrared Port An IR port is a port which sends and receives infrared signals from other devices.

It is a wireless type port with a limited range of ft. Bluetooth Bluetooth uses short-range radio frequencies to transmit information from fixed and mobile devices. These devices must be within the range of 32 feet, or 10 meters for Bluetooth to effectively work. A Bluetooth port enables connections for Bluetooth-enabled devices for synchronizing.

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 converts the HLL language into machine language in one go. Interpreter It is a translator which converts and executes the HLL language code 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 Register 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.
