What is mouse and types
Computer Mouse A computer mouse is a handheld hardware input device that controls a cursor in a GUI and can move and select text , icons , files , and folders . For desktop computers, the mouse is placed on a flat surface such as a mouse pad or a desk and is placed in front of your computer. The picture to the right is an example of a desktop computer mouse with two buttons and a wheel. Who invented the mouse? The mouse was originally known as the X-Y Position Indicator for a Display System and was invented by Douglas Engelbart in 1963 while working at Xerox PARC . However, due to Alto's lack of success, the first widely used application of the mouse was with the Apple Lisa computer . Today, this pointing device is on virtually every computer. What are the functions of a mouse? Below is a list of each of th...
Heat sink
Heat sink A fan-cooled heat sink on the processor of a personal computer. To the right is a smaller heat sink cooling another integrated circuit of the motherboard. A heat sink (also commonly spelled heatsink [1] ) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature at optimal levels. In computers, heat sinks are used to cool central processing units or graphics processors . Heat sinks are used with high-power semiconductor devices such as power transistors and optoelectronics such as lasers and light emitting diodes (LEDs), where the heat dissipation ability of the component itself is ...
Network card
Network interface controller A network interface controller ( NIC , also known as a network interface card , network adapter , LAN adapter or physical network interface , [1] and by similar terms) is a computer hardware component that connects a computer to a computer network . [2] Network interface controller A 1990s Ethernet network interface controller that connects to the motherboard via the now-obsolete ISA bus . This combination card features both a BNC connector (left) for use in (now obsolete) 10BASE2 networks and an 8P8C connector (right) for use in 10BASE-T networks. Connects to Motherboard via one of: Integrated PCI Connector ISA Connector PCI-E FireWire USB Thunderbolt Network via one of: Ethernet Wi-Fi Fibre Channel ATM FDDI Token...
