It’s important for any business that utilises technology and computers to understand the basics of the computer hardware components they are using. Without the adequate hardware, your software may not run efficiently – if at all. It’s important to stay informed about the equipment your business uses, as it can greatly impact your productivity. The rest can be left to your business IT support provider! Show Firstly, what is IT hardware? Put simply, IT hardware refers to any physical or tangible elements of a computer. IT hardware helps to facilitate any computing operations as well as taking input and outputting or storing the computed results. There are four main computer hardware components that this blog post will cover: input devices, processing devices, output devices and memory (storage) devices. Collectively, these hardware components make up the computer system. Input Devices Input devices comprise of any devices that users need in order to give instructions to a computer. Essentially input devices act as the medium for sending data to a computer so that users can interact with and control it. The most widely known examples are the keyboard and mouse. Input devices are also used to transfer data between computers. Output Devices Output devices are devices that allow computers to send data to other devices or to users. In general, the data that computers send to human users is in forms that we can understand. Most often, these forms include audio and video. The most widely known examples of output devices are monitors, speakers and printers. These devices produce video, audio and graphic output, respectively. Processing Devices Processing is the core function of any computer. When a computer receives data from an input device, this data must first go through an intermediate stage before it is sent to an output device. Processing is the intermediate stage where raw data is transformed into information so that it can be outputted meaningfully for the user. An example of a processing device is the central processing unit (CPU), which is a set of electronic circuitry that processes and executes instructions. Memory (Storage) Devices Memory devices are any devices that are capable of storing information temporarily or permanently. There are two types of memory; primary and secondary. Primary memory refers to RAM (random access memory), which is used to store instructions and data temporarily before and after they are processed. RAM is volatile, which simply means it only retains information when the computer is turned on and is cleared once the computer turns off. Secondary memory refers to any external storage media. Secondary memory is non-volatile, which means that information can be stored long-term. The most common example of an external secondary memory device is the USB flash drive. Alfred is a long-time teacher and computer enthusiast who works with and troubleshoots a wide range of computing devices. There are three major components of a computer system:
While hardware and software components co-exist to make up the actual computer, the humanware component adds in the human face to bring the complete computer into a functional and productive existence. When installed separately, each may be useful to an extent but incapable of achieving complete computing potential. Hardware and software need the human factor in order to make input and connectivity possible. 1. Computer HardwareThese are computer system components that can be touched by the human hand. Examples include:
These parts are housed within the laptop or the desktop system-unit. For the desktop, however, the keyboard and mouse are attached and used externally. The most important piece of hardware is the microprocessor chip, which is commonly known as the central processing unit (CPU). New and slim laptop computers merge the traditional CPU and the graphics processing chip (GPU) into what is called accelerated processing unit (APU). These chips are usually attached to the motherboard in these laptops. The CPU and APU are responsible for all arithmetic and graphics manipulation. A component just as important is the disk drive. This is where computer data is stored. It is classified as secondary memory. There are two popular types of disk drives to choose from. Hard disk: This drive is mechanical by design and stores data on magnetic and metallic platters. Its data is read magnetically by read/write heads which make it reliant on an uninterrupted supply of power. A sudden power outage can lead to data loss or drive failure. It must be used properly for the sake of data integrity and long lifespan. Solid state disk: This new type of disk drive stores data on flash memory chips and is less prone to erratic behavior. It is faster and reliable even in the event of sudden power outages. Another vital part within a system is the motherboard. It provides communication and direct connectivity to devices throughout the computer. Connectivity to a motherboard can be internal or external. Internal devices that connect to the motherboard include:
External peripherals that connect to the motherboard include:
2. Computer SoftwareThe software component refers to the instructions, programs, data, and protocols which run on top of hardware. It is also retained temporarily and persistently in primary and secondary hardware media. The random access memory chip is an example of primary hardware while the hard disk drive is an example of secondary hardware. Software can be divided into system, application, malicious and programming categories. System SoftwareThe system manages other software and devices inside the computer. The foremost example of system software is the operating system (OS). In a typical setup, the operating system is like the motherboard for software. It is the first thing that is installed, followed by applications and other software. Three popular operating systems for traditional computers include Windows, Mac OS X, and Linux. Popular mobile operating systems include Android OS, iPhone OS, Windows Phone OS, and Firefox OS. Application SoftwareThis is designed for end-users to perform a specialized assignment in order to output useful information. An example would be a word processing application used to compose letters or brochures, such as Microsoft Word. Other popular examples include Adobe Photoshop, Corel Draw, and AutoCAD. A collection of application software is bundled in a package that is commonly known as a software suite. A typical suite includes software for word processing, presentation, graphic design, and spreadsheet. Examples include Microsoft Office, OpenOffice, and iWork. Software is written in computer languages such as Visual Basic, C, and Java. Malicious SoftwareMalware is short for malicious software, which is a generic term that refers to exploitative code designed by criminals and black hat hackers to maim normal operations of a computer. Malware attacks can result in data loss and hacker access to private information. Affected computers can also be converted into zombies and used in a bigger mission of criminal activities like launching denial of service attacks (DOS) and spreading spam. Malware scripts are delivered to the computer as viruses, trojans, rootkits, keyloggers, worms, or through email and websites as adware, spyware, ransomware and scareware. Programming SoftwareThese are tools used by developers to create all kinds of software like Windows OS and Word processing. Also called languages, they are used to write source codes, debug errors, maintain and create new software for computers and write malicious scripts like viruses and trojans. Popular examples of high-level languages are Java, Javascript, BASIC, PHP, Visual Basic, Visual C++, Visual Basic, Python, Ruby, Perl, Java. 3. HumanwareThe humanware component refers to the person that uses the computer. More specifically, it is about the individual that makes hardware and software components productive. Typically, a great deal of testing is done on software packages and hardware parts to ensure they enhance the end-user experience to aid in creating documents, musical and video recordings, and all forms of raw and finished data. The Analogy of Components of a ComputerIn a nutshell, a working computer system can be compared to a functioning kitchen.
Even after purchasing the freshest ingredients and the finest pots and pans, there will not be a good meal without a chef. He/she will make good use of listed recipes to make good of the ingredients and utensils. Both hardware and software are complemented by the works of a human to produce a fully functional computer system.
