Assignment 2 calculate the total price to purchase all the components required to build a state of the art gaming computer from components available on the internet. Process: the program will know the predetermined costs of the other components, basecost. The input consists of the cpu choice, the motherboard choice, and hard drive choice submodules, cpu_choice, mb_choice, and hdd_choice. The program will determine the corresponding cost of the options: cpucost, mbcost, and hddcost.

The total cost of the computer system is calculated by the sum of all the individual components for the system the basecost casecost + powersupplycost + motherboardcost + harddrivecost + ramcost + dvdcost + soundcardcost + monitorcost + graphicscardcost + operatingsystemcost the totalsystemcost cpucost + mbcost + hddcost + basecost output: the user’s choices, the total system price in usd step 1. The main module will call compute_cpu_choice, compute_mb_choice, and compute_hdd_choice submodules or terminate the program. The program will add the totalsystemcost cpucost + mbcost + hddcost + basecost step 5. //sum the base cost for the system a computer system is a programmable electronic/mechanical machine that receives inputted data, stores it and manipulates it, then outputs it in a useful format which is then sent visually to an external monitor and shown to the user via a gui, this is interactive.

These useful formats are provided by the built in operating system, which is basically the main converter of data. A computer can be used to do almost anything with the right hardware and programming, you can watch/encode/decode movies, word process, internet access, play high quality interactive games, generate programmed environments to create 3d and 2d examples of products. Below i will explain each component, one by one, outlining their specific roles and relationships within on a standard pc.

Essay writing service essay marking service place an order the main body components of a pc are: the chassis/computer case. This is a plastic or metallic styled enclosure that houses all the interior fundamental computer components such as the power supply, motherboard, cpu and its heat sink/fan, hard drives, graphics card, ram and optical disk drives such as cd/dvd/blue ray.

It protects the fragile computer components from outside harmful stimuli, such as electric/static irregularities which if come in contact with the inner computer parts could damage the pc. It also provides a stylish overall look fashioned to a user's specific taste, such as the gaming pc above, which is tailored to a hard core gamers tastes. The chassis also provides maximum air flow and spacing allowing for a cool and stable pc.

This is why most computer cases come with included fans which connect to the power supply, to distribute the extra heat to the outside surroundings, to improve airflow and to ultimately stabilise the pc. The motherboard is said to be the mother of the main computer components, it is the foundation circuit board which all the other fundamental components connect to, via ports and buses. Motherboards also typically incorporate a built in graphics chip that is a processing unit that handles 2d/3d video and interactive representations, such as high definition movies and games. However these graphic chips are only designed to be used for movies, and low processing intensive games and activities, a separate graphics card is added for more strenuous computing activities. Most fundamentally in my opinion is the power supply, this provides sufficient power to each computer component it regulates the power to optimum levels so the flow of electricity between components is controlled, preventing over and underpowered components.

Without this the computer would most likely not act at its highest efficiency and potential, leading to burnt out components and in turn the computers death. The power supply also houses an efficient fan to lower its heat intake and outtake. Metaphorically i'd compare the power supply to a human's heart, the power flow being compared to the blood route. Major components that are connected to the motherboard are: the cpu is the central processing unit, which is technically the brain of the computer. It is a microprocessor which performs most of the calculations, instructions and facilitates simultaneous operations which enables the computer to function. Everything that the computer does is overseen and to an extent controlled by this core component. Because this is the brain cpu of the computer, the sheer amount of calculations and information it has to instruct creates a big amount of heat, this is where its heat sink and fan come into play.

The heat sink transfers the cpu's generated heat to the fan which then rotates and gets turned into escapable air. This core part sufficiently cools down the cpu so it can continue calculating at its optimum effectiveness. It is a form of internal data storage that is directly connected and used by the cpu, it is a lot faster than data storage devices such as hard disks and is used to store open programs and writes as well as reads important data more efficiently and rapidly. It allows for a faster retrieval of information which increases program load speed and increases the systems efficiency.

Larger amounts of ram and faster ddr2, ddr3 and ddr5 models with numerous speeds are ideal when using memory intensive programs such as gaming, encoding/decoding and using cad and other intensive applications. Without sufficient ram, such as 1gb, 2gb, 4gb, and 8gb+ the system would be sluggish and information would not be as quickly accessed resulting in loss of user experience. This is not an archival data storage device because unlike hard drives, ram does not retain its information when the pc is powered off. Who wrote this essay request removal example essays hard drives, these are large capacity data storage devices that retains its stored information, this is where all the systems programs, files, operating system and user documents, music, videos are stored. Although in comparison common hard drives incorporate moving parts to operate and store data, the drive has platters which is where it stores data. The drive spins the platters to write and read data these can be more prone to failures.

However newer, solid state drives , acronym sdd are overcoming this disadvantage, they are flash based devices which have no moving parts. Instead of its electromechanical counterparts, ssd's use microchips to hold data, which decreases access time and decreases the risk of damage from physical shock. This however increases its price, meaning only the financially adept are more inclined to choose this option. Typical hard drive capacities range from 40gb to a massive 2tb+ 1 terabyte being 10gb , these larger capacities are ideal for servers and users that require larger disk space such as movie rendering producers. Ssds, due to their flash components are at the moment lacking enormous capacities compared to its traditional counterparts, nevertheless larger capacities are being developed but at prices too high for the everyday user.

Current hard drive speeds range from 5400rpm revolutions per minute to 10,0 rpms, with 7200rpm being the current norm. A decent amount of cache a kind of built in ram also plays a large part and combined with a good mean rpm, produces speedy saving and recovery of data. This however, when compared with solid state drives, seems feeble when a traditional ssd is on average 50%+ percent faster, which provides a massive speed improvement in everyday computing situations. Other advantages of solid state drives are that they require less power, because it doesn't contain any continuously spinning parts, it is quieter and is more shock resistant. The argument whether the speed improvement warrants the significant price increase is obviously a very debated topic, and in my opinion to the average public the pricing is too significant to be a viable rival, this however will change with time.
