Computer accessories are items that accompany a computer. They include things such as a mouse, keyboard, USB technology, cooling fans and power supply units. Computer Cases and Towers refers to the enclosure that contains most of the components of a computer. They are usually constructed from steel or aluminium. Plastic is sometimes used and other materials such as glass, wood and even lego has appeared in home-built cases.
Computer cooling fans refers to any fan that is inside, attached to or a computer case used for active cooling and may refer to fans that draw cooler air into the case from outside, expel warm air from inside or move air across a heat sink to cool a particular component.
Mouse and Keyboards are devices that are used in conjunction with a desktop computer. A mouse is a pointer divide that is handheld. A keyboard is a typewriter style device that allows the input of data.
Computer Cases and Towers refers to the enclosure that contains most of the components of a computer. They are usually constructed from steel or aluminium. Plastic is sometimes used and other materials such as glass, wood and even lego has appeared in home-built cases. Cases can come in many different sizes. The size and shape of a computer case is usually determined by the form factor of the motherboard, since it is the largest component of most computers. Consequently, personal computer form factory typically specify only the internal dimensions and layout of the case. Form factors for rack-mounted and blade servers may include precise external dimensions as well, since these cases must themselves fit in specific enclosures.
Computer cooling fans refers to any fan that is inside, attached to or a computer case used for active cooling and may refer to fans that draw cooler air into the case from outside, expel warm air from inside or move air across a heat sink to cool a particular component. Generally these are found in axial and sometimes centrifugal forms. The former is sometimes called an electric fan. Processors, graphics cards, RAM and other components in computers have increased in speed and power consumption, the amount of heat produced by these components as a side-effect of normal operation has also increased. These components need to be kept within a specified temperature range to prevent overheating, instability, malfunction and damage leading to a shortened component lifespan
Webcams are a video camera that feeds or streams its image in real time to or through a computer to a computer network. when captured by the computer, the video stream may be saved, viewed or sent on to other networks travelling through systems such as the internet and e-mailed as an attachment. When sent to a remote location, the video stream may be saved, viewed or sent there. Unlike an IP camera, which connects using Ethernet or Wifi, a webcam is generally connected by a USB cable, or similar cable, or built into computer hardware, such as laptops.
USB Gadgets are items that are plugged into the USB port on a computer. These can be items that are accessories to a computer or a fun gadget. USB's are used to attach items such as a keyboard, a mouse or some varieties of headphones. They can also be used for phone charging cables and accessories, desk fans and can also be used to plug in external storage such as a flash drive or an external hard drive. Webcams can also be attached using a USB port. Devices such as a Sat Nav can be attached to a computer via USB in order to upload any updates the system may require.
Tablet PC Stands allow tablets to be stood upright whilst it is being used. This comes in handy when a film or TV is being viewed, or the tablet is being used in conjunction with a keyboard. Stands can be separate from the tablet, as in the tablet can be moved from the stand when not in use, or they can be built into the protective case the user is storing the tablet in, giving it several used in one. Tablet PC's are a mobile device that typically uses a mobile operating system to function. They commonly have an LCD touchscreen and a rechargeable battery. They have the capabilities to be used in the same way as a regular laptop.
Tablet PC computers, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and LCD touchscreen display processing circuitry and a rechargeable battery in a single, thin package. Tablets, being computers, do what other personal computers do, but lack some I/O capabilities that others have. Modern tablets largely resemble modern smartphones, the only difference being that tablets are relatively larger than smartphones, with screens 7 inches or larger, measured diagonally and may not always support access to a cellular network.
Sound Cards are an internal expansion card that provides input and output of audio signals to and from a computer under control of computer programmes. The term sound card is also applied to external audio interfaces used for professional audio applications. Sound functionality can also be integrated onto the motherboard, using components similar to those found on plug-in cards. The integrated sound system is often still referred to as a sound card. Sound processing hardware is also present on modern video cards with HDMI to output sound along with the video using that connector; previously used a SPDIF connection to the motherboard or sound card.
Servers are a computer program or a device that provides functionality for other programs or devices, called 'clients'. This architecture is called the client-server model and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called services, such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers.
Processors, also known as a processing unit, in computing, is an electronic circuit which performs operations on some external data source, usually memory or some other data stream. The term is frequently used to refer to the central processor, or central processing unit, in a system, but typical computer systems, especially SoCs, combine a number of specialised processors. For this there are several types, including: the graphics processing unit, the video processing unit and the digital signal processor along with many more.
Pen USB Flash Drives are a data storage device that includes flash memory with integrated USB interface. It is typically removable, rewritable and much smaller than the optical disc. Most weigh less than 1 ounce. Since first appearing on the market in late 2000, as with virtually all other computer devices, storage capacities have risen while prices have dropped. As of March 2016, flash drives with anywhere from 8 to 256GB are frequently sold. They are handy because they are portable, meaning the user can view files on any computer as long as they plug in the drive.
PC Stations are a special computer that is designed for technical or scientific applications. Intended primarily to be used b one person at a time, they are commonly connected to a local area network and run multi-user operating systems. The term workstation has been used to loosely refer to everything from a mainframe computer terminal to a PC connected to a network. Work stations offered higher performance than mainstream personal computers, especially with respect to graphics, capacity and multitasking capabilities.
Optical Drives, in computing, is a disc drive that uses laser light electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, but recent drives can both read and record, also called burners or writers. Compact discs, DVDs and Blu-ray discs are common types of optical media which can be read and recorded by such drives.
Mouse Pads are a surface for placing and moving a computer mouse. A mouse pad enhances the usability of the mouse compared to using a mouse directly on a table by providing a surface to allow it to measure movement accurately without jitter. Some mousepads increase ergonomics by providing a padded wrist rest. The three most important benefits to the mouse pad are higher speed, more precision and more comfort for the user. Another benefit is preventing the desk becoming scratched, which would also hinder the use of the mouse.
Mouse and Keyboards are computer accessories that are used to input data. A computer mouse is a hand held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface. In computing, a keyboard is a typewriter-style device which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input method for computers.
Motherboards are the main printed circuit board found in general purpose microcomputers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems such as the central processor, the chipset's input/output and memory controllers, interface connectors and other components integrated for general purpose use and applications.
Monitors are an output device that displays information in a pictorial form. They are usually commented to a computer. A monitor usually comprises the display device, circuitry, casing and power supply. The display device in modern monitors is typically a think film transistor liquid crystal display with LED backlighting having replaced cold-cathode fluorescent lamp backlighting. Older monitors used a cathode ray tube. Monitors are connected to the computer via VGA, Digital Visual Interface (DVI_ HDMI, DisplayPort, Thunderbolt, low-voltage differential signalling or there proprietary connectors and signals.
Memory Modems are a network hardware device that modulates one or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used with any means of transmitting analog signals, from light-emitting diodes to radio. A common type of modem is one that turns the digital data of a computer into a modulated electrical signal for transmission over telephone lines and demodulated by another modem at the receiver side to recover the digital data.
Keyboard Covers are a protective or decorative measure used in conjunction with a computer keyboard. Keyboard covers can be used to keep dust and crumbs off keyboards. They are often made from a thin, flexible plastic material that has been pre-molded to fit the design of the keyboard. They are produced so that the keyboard can be used whilst the cover is on. The aim of the cover is to prevent dust or crumbs entering the keyboard and potentially disrupting its inner workings. A decorative keyboard cover consists on a series of highly decorative stickers being applied to each key in order to give a bright and interesting effect.
Hard Drives, hard disk drives or a hard disk is a storage device for computers. The capacity of a hard drive is usually measured in gigabytes, however hard disk capacity can also be measured in terabytes when the capacity is over 1000 gigabytes. A gigabyte is one thousand megabytes and a megabyte is one million bytes. Computers are often manufactured with a built-in hard drive for information to be stored, but external hard drives are also available, where a user can purchase the hard drive, connect it to a computer via USB and download their files, videos and information onto that. It gives an extra level of safety also, in the case of the computer becoming damaged or stolen the files are not lost.
Graphics Cards are an important piece of graphics hardware. It is a piece of equipment that renders out all images and sends them to a display. There are two types of graphics card: integrates and dedicated. An integrated graphics card is bound to the motherboards and shares RAM with the CPU, reducing the total amount of RAM available. This is undesirable for running programmes and applications that use a large amount of video memory. A dedicated graphic card has its own RAM and processor for generating its images and does not slow down the computer.
Computer Cleaners are computing programmes that are designed to free up disk space on a computers hard drive. The utility first searches and analyses the hard drives for files that are no longer of any use and then removes the unnecessary files. The existing files are then ordered so as to free up space and organise the files on the drive. There are a number of different file categories that cleaners target when performing the initial disk analysis, including temporary internet files, downloaded files and the recycle bin..
