Components Of A Computer System

Components Of A Computer SystemComputer is an electronic machine that can store, organize and research information, do calculation and control other machines. Computer has potentware and also bundle.Computer hardware way of life the physical component of a estimator dodge, which has divers(prenominal) functions to complete different tasks. Hardware is something we can touch. This hardware includes input devices, emergeput devices, a system unit, storage devices, and communications devices. This could be a monitor, reminiscence chip, hard shoot, or CPU.Computer software is the collection of computer programs and related data that provide the instructions telling a computer what to do and how to do it. software program refers to one or more computer programs and data held in the storage of the computer for some purposes. Program software performs the function of the program it implements, either by directly providing instructions to the computer hardware or by serving as inp ut to another piece of software. Software is intangible. Examples of software are use software and system software. With turn out software, hardware is useless.hero_06_software.jpgComputer SpecificationEach computer has own computer specification. The computer that Im going to discuss about its specification is HP ProBook 4420s.HP-ProBook-4420s-Notebook-PC_400x400.jpgProcessor Intel Core i3-370M Processor (2.4 GHz, 3 MB L3 cache) retention 2 GB 1066 MHz DDR3 SDRAMChipset Mobile Intel HM57 pull upOperating System Windows 7 netGraphic card ATI Mobility Radeon HD 5470 with 512 MB dedicated video memory intrinsic drive 320 GB 7200 rpm SATA IIOptical disk drive videodisc+/-RW SuperMulti DL LightScribeDisplay 14.0 diagonal LED-backlit HD anti-glare (1366 x 768)Integrated camera 2.0 MP webcamWeight and dimension- 2.27 kg, 33.60 x 23.24 x 2.70 cmBattery type and life 6-cell (47 WHr) Li-Ion, up to 4 hours and 30 minutesProcessorThe processor of this laptop is Intel Core i3-370M. Processor is also called the central processing unit (CPU). It is the electronic component that interprets and carries out the basic instructions that operate a computer. Furthermore, it is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computers functions. The central processing unit carries out each instruction of the program in sequence, to perform the basic arithmetical, logical, and input/output operations of the system.System quantifyThe processor relies on a small quartz crystal circuit called the system time to control the timing of all computer operations. The pace of the system clock, called the clock speed, is measured by number of ticks per second. The clock speed for this processor of this laptop is 2.40GHz (Giga Hertz). The clock rate is the speed at which a microprocessor executes instructions. Every computer contains an internal clock that regulates the rate at which instruction s 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.CacheMost of todays computers improve their processing times with cache. Memory cache helps speed the processes of the computer because it stores frequently used instructions and data. This laptop is having L3 cache on the motherboard which is separate from the processor chip.MemoryMemory is the primary storage. It consists of electronic components that store instructions waiting to be executed by the processor, data needed by those instructions, and the results of processing the data which is information. Most Random approach memory (RAM) is volatile, which means it loses its contents when the power is removed from the computer. The RAM of this laptop is 2 GB 1066 MHz DDR3 SDRAM. SDRAM refers to Synchronous DRAM, which can synchronized to the syst em clock and it is such(prenominal) faster than DRAM.ChipsetChipset of this laptop is Mobile Intel HM57 Express. A chipset refers to a group of integrated circuits, or chips, that are designed to work together. They are usually marketed as a single product. It is usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset is used to determine the system performance.The mobile Intel HM57 Express Chipset is part of the mobile Intel 5 Series Chipsets, providing single chip architecture and deliveringIntel Anti-Theft Technology for PC protection that can disable a lost or stolen PC and reactivate it without compromise to the system or dataBlue-ray* logo capable HD video playback, with ingrained support for Blue-ray drivesIntel Rapid Storage Technology for intensify performance, power management, and data protection for the storage subsystemOperating SystemAn operating system (OS) is sof tware, consisting of programs and data, that runs on computers and manages computer hardware resources and provides common services for efficient functioning of various application software. Examples of popular modern operating systems for personal computers are Microsoft Windows, Mac OS X, and GNU/Linux. The operating system that installed in this laptop is Windows 7 Ultimate 64-bit.Graphic CardThe graphic card included in this laptop is ATI Mobility Radeon HD 5470 with 512 MB dedicated video memory. This graphic card has 512MB of dedicated DDR3 VRAM (Video RAM), which means it has 512MB for storing data (not combining with computer RAM). The higher the memory of VRAM, the better the graphical item (such as picture, video, and game loading) can be presented and better loading time.Internal driveThe hard disk included in this laptop is 320 GB 7200 rpm SATA II. A hard disk drive (HDD) is a non-volatile, random access device for digital data. It features rotating rigid criminal reco rds on a motor-driven spindle within a protective enclosure. Data is magnetically read and written on the platter by read/write heads that float on a film of air above the platters. SATA II is the second generation SATA interfaces running at 3.0 Gbit/s are shipping in high volume as of 2010update, and prevalent in all SATA disk drives and the majority of PC and server chipsets. With a native transfer rate of 3.0 Gbit/s, and taking 8b/10b encoding into account, the maximum uncoded transfer rate is 2.4 Gbit/s (300 MB/s).Optical disc driveThe optical disc drive in this laptop is DVD+/-RW SuperMulti DL LightScribe . It is support for the Blu-ray DVD drive on configurations with integrated graphics requires Windows7 or Windows Vista. Optical disc drives are an inherent part of stand-alone consumer appliances such as CD players, DVD players and DVD recorders. They are also very commonly used in computers to read software and consumer media distributed in disc form, and to record discs fo r archival and data exchange.OthersThe display of this laptop is 14.0 diagonal LED-backlit HD anti-glare (1366 x 768). Furthermore, this laptop is only weighed 2.27 kg and has a dimension of 33.60 x 23.24 x 2.70 cm. This laptop of has a webcam which is 2.0MP. Meanwhile, this laptop use the battery of 6-cell (47 WHr) Li-Ion and it can last up to 4 hours and 30 minutes.Analysis of Overall PerformanceThis laptop is using a processor of Intel Core i3-370M Processor.
