Computers Hardware and Software ( Modern Technology)

  1. 1. Computer Hardware & Software Devices LATEST DEVICES USING MODERN TECHNOLOGY SUBMITTED TO SIR GHULAM MURTAZA ASSIGNMENT BY SHAHZEB
  2. 2. Computer Hardware & Software  A computer system consists of two major elements: hardware and software.  Computer hardware is the collection of physical parts of a computer system. This includes the computer case, monitor, keyboard, and mouse. It also includes all the parts inside the computer case, such as the hard disk drive, motherboard, video card, and many others. Computer hardware is what you can physically touch.  Computer software, on the other hand, is not something you can touch. Software is a set of instructions for a computer to perform specific operations.
  3. 3. Types of Computer Hardware  Input Devices; An input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system.  Output Devices; An output device is any device used to send data from a computer to another device or user.  Storage Devices; An storage device is a piece of computer equipment on which information can be stored.  Communication Devices; Communication devices are the machines that assist in transmission of data.
  4. 4. Input Devices using Latest Technology Vivo Mouse Vivo Mouse is an innovative three-in-one input device that functions as a mouse, touchpad and wireless remote. Its versatility, coupled with an ambidextrous, hand-fitting design and full support for Windows 8.1/8 gestures, makes Vivo Mouse convenient and comfortable to use for right- and left-handed users alike. It works interchangeably as an optical mouse and desktop touchpad, so it is an ideal input device for Windows 8.1/8 PCs without multi-touch displays. With its wireless PC connection, Vivo Mouse also works great in the living room as a remote control for a home theater PC.
  5. 5. Input Devices using Latest Technology RFID RFID stands for Radio-Frequency Identification. The acronym refers to small electronic devices that consist of a small chip and an antenna. The chip typically is capable of carrying 2,000 bytes of data or less. The RFID device serves the same purpose as a bar code or a magnetic strip on the back of a credit card or ATM card; it provides a unique identifier for that object. And, just as a bar code or magnetic strip must be scanned to get the information, the RFID device must be scanned to retrieve the identifying information.
  6. 6. Input Devices using Latest Technology Digitizer Digitizer is an input device which converts analog information into digital form. Digitizer can convert a signal from the television or camera into a series of numbers that could be stored in a computer. They can be used by the computer to create a picture of whatever the camera had been pointed at. Digitizer is also known as Tablet or Graphics Tablet because it converts graphics and pictorial data into binary inputs. A graphic tablet as digitizer is used for doing fine works of drawing and image manipulation applications.
  7. 7. Input Devices using Latest Technology Bar Code Reader Bar Code Reader is a device used for reading bar coded data (data in form of light and dark lines). Bar coded data is generally used in labelling goods, numbering the books etc. It may be a hand held scanner or may be embedded in a stationary scanner. Bar Code Reader scans a bar code image, converts it into an alphanumeric value which is then fed to the computer to which bar code reader is connected.
  8. 8. Input Devices using Latest Technology Touchscreen Monitor These devices double as an output and input device. They display the computer environment on screen, and allow a user to manipulate and interface with it just by touching the screen. These can take the place of a mouse and even a keyboard if a virtual keyboard application is installed.
  9. 9. Output Devices using Latest Technology 3D Printer The 3D printer is a printing device that creates a physical object from a digital model using materials such as metal alloys, polymers, or plastics.
  10. 10. Output Devices using Latest Technology 3D projectors 3D projectors filling screens typically from 92″ diagonal to 130″ diagonal, is a game changer. Like in a theater, you are immersed in 3D, not looking at some small 3Dbox. 3D projectors are now being used for home theater, for 3D gaming, in education, and for specialty business and scientific applications.
  11. 11. Output Devices using Latest Technology 3D Display A stereo display (also 3D display) is a display device capable of conveying depth perception to the viewer by means of stereopsis for binocular vision.
  12. 12. Output Devices using Latest Technology Headphones Headphones (or head-phones in the early days of telephony and radio) are a pair of small listening devices that are designed to be worn on or around the head over a user's ears.
  13. 13. Output Devices using Latest Technology Plotter A plotter is a printer that interprets commands from a computer to make line drawings on paper with one or more automated pens.
  14. 14. Storage Devices Using Modern Technology Buffalo Drive Station DDR The Buffalo Drive Station DDR is a USB 3.0 desktop external hard drive that's the first to incorporate 1GB of DDR3 system memory as cache, and in doing so offers an unprecedented superfast data rate. The drive offers a real-world sustained data transferal speed of more than 200MBps.
  15. 15. Storage Devices Using Modern Technology Flash Drive A flash drive is a small, ultra-portable storage device which, unlike an optical drive or a traditional hard drive, has no moving parts. Flash drives connect to computers and other devices via a built-in USB plug, making a flash drive a kind of combination USB device and cable. One of the first flash drives was just 8 MB in size. The largest one I'm aware of is a USB 3.0 flash drive with a 1 TB (1024 GB) capacity.
  16. 16. Storage Devices Using Modern Technology Secure Digital Card An SD Card (Secure Digital Card) is an ultra small flash memory card designed to provide high- capacity memory in a small size. SD cards are used in many small portable devices such as digital video camcorders, digital cameras, handheld computers, audio players and mobile phones. In use since 1999, SD Memory Cards are now available in capacities between 16 Megabytes and 1Gigabyte. An SD card typically measures 32 x 24 x 2.1 mm and weighs approximately 2grams.
  17. 17. Storage Devices Using Modern Technology Synology DS412+ The Synology DS412+ is a four-bay NAS system that currently offers the best balance when it comes to performance, features, storage space, and cost. With hard drives currently capping at 4TB, the servers offer up to 16TB of raw storage space or 12TB of protected storage space. Like any NAS server from Synology, it runs the Disk Station Manager firmware to offer a vast amount of features and functions that can be managed via a robust Web interface. It's also one of the fastest NAS servers on the market.
  18. 18. Storage Devices Using Modern Technology Seagate Backup Plus The Backup Plus (available in 500GB, 750GB, and 1TB capacities) is the latest portable hard drive from Seagate. As its name implies, is known for being extremely flexible. You can use any type of peripheral connection with it, be it USB, FireWire, Thunderbolt, or e SATA, via separate adapters. You can also use the included adapter to quickly connect any 2.5- inch internal drive to a computer.
  19. 19. Communication Devices using Modern Technology Modem A modem (modulator-demodulator) is a network hardware device that modulates one or more carrier wave signals to encode digital information for transmission.
  20. 20. Communication Devices using Modern Technology Router A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet.
  21. 21. Communication Devices using Modern Technology Bluetooth USB Adapter A Bluetooth USB-based Adapter device that transmits and receives Bluetooth wireless signals. It plugs into the USB port to support Bluetooth mice, keyboards and other Bluetooth devices. Also called a "Bluetooth dongle."
  22. 22. Communication Devices using Modern Technology Wi-Fi Wi-Fi or WiFi is a local area wireless computer networking technology that allows electronic devices to connect to the network, mainly using the 2.4 gigahertz (12 cm) UHF and 5 gigahertz (6 cm) SHF ISM radio bands.
  23. 23. Communication Devices using Modern Technology Network Switch A network switch is a computer networking device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device.
