First Computer
Charles Babbage invented the concept of a programmable computer in about 1856. -
Movie Camera
One of the first motion-picture film cameras was designed by Louis Le Pickle in 1888. It still exists with the National Media Museum, England. Le Prince employed paper bands and celluloid film from John Carbutt and or Blair & Eastman in 1¾ inch width. The first motion picture camera that actually worked was created by Thomas Alva Edison.
On June 21 1889, William Fries-Greener was issued patent no. 10131 for his 'chronophotographic' camera. It was apparently capable of taking up to ten photograp -
Computer Virus
The first academic work on the theory of computer viruses (although the term "computer virus" was not used at that time) was done in 1949 by John von Neumann who held lectures at the University of Illinois about the "Theory and Organization of Complicated Automata". The work of von Neumann was later published as the "Theory of self-reproducing automata". In his essay von Neumann described how a computer program could be designed to reproduce itself.[4] -
First Hard Drive
The IBM 350 Disk File, considered to be the first hard disk drive, was invented in 1956 by an IBM team led by Reynold Johnson. -
Hard Disk Drive
The capacity of hard drives has grown exponentially over time. When hard drives became available for personal computers, they offered 5-megabyte capacity. During the mid-1990s the typical hard disk drive for a PC had a capacity of about 1 gigabyte As of July 2010, desktop hard disk drives typically had a capacity of 500 to 1000 gigabytes, while the largest-capacity drives were 4 terabytes. -
Discovered the internet!
J.C.R. Licklider was the first to describe an Internet-like worldwide network in 1962. -
Creation of Floppy Disk!
Floppy disks were introduced in 1971 by IBM. -
Laptop
A laptop, also called a notebook,[1][2] is a personal computer for mobile use.[3][4] A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, and/or a pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. -
Software!
United States that develops, manufactures, licenses, and supports a wide range of products and services predominantly related to computing through its various product divisions. Established on April 4, 1975 to develop and sell BASIC interpreters for the Altair 8800, Microsoft rose to dominate the home computer operating system market with MS-DOS in the mid-1980s, followed by the Microsoft Windows line of operating systems. -
Creation of the ethernet!
Ethernet has largely replaced competing wired LAN technologies. Systems communicating over Ethernet divide a stream of data into individual packets called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted. -
Network Security
The main issue with wireless network security is its simplified access to the network compared to traditional wired networks such as ethernet.[citation needed] With wired networking one must either gain access to a building (physically connecting into the internal network) or break through an external firewall. Most business networks protect sensitive data and systems by attempting to disallow external access. Enabling wireless connectivity reduces security if the network uses inadequate. -
Standard Access point!
A wireless access point (WAP) connects a group of wireless devices to an adjacent wired LAN. An access point resembles a network hub, relaying data between connected wireless devices in addition to a (usually) single connected wired device, most often an ethernet hub or switch, allowing wireless devices to communicate with other wired devices. -
Wireless Network
Wifi, is a mechanism that allows electronic devices to exchange data wirelessly over a computer network. A device enabled with Wi-Fi, such as a personal computer, video game console, smartphone, tablet, or digital audio player, can connect to a network resource such as the Internet via a wireless network access point. An access point (or hotspot) has a range of about 20 meters (65 ft) indoors and a greater range outdoors. Hotspot coverage can comprise an area as small as a single room with walls -
Webcam
A webcam is a video camera that feeds its images in real time to a computer or computer network, often via USB, ethernet, or Wi-Fi. Their most popular use is the establishment of video links, permitting computers to act as videophones or videoconference stations. This common use as a video camera for the World Wide Web gave the webcam its name. Other popular uses include security surveillance and computer vision and there are also uses on sites like video broadcasting services and for recording -
Spyware
Spyware is a type of malware (malicious software) installed on computers that collects information about users without their knowledge. The presence of spyware is typically hidden from the user and can be difficult to detect. Typically, spyware is secretly installed on the user's personal computer. Sometimes, however, spywares such as keyloggers are installed by the owner of a shared, corporate, or public computer on purpose in order to secretly monitor other users. -
Multiple Acces points
Increasing the number of Wi-Fi access points provides network redundancy, support for fast roaming and increased overall network-capacity by using more channels or by defining smaller cells. Wi-Fi implementations have moved toward "thin" access points, with more of the network intelligence housed in a centralized network appliance, relegating individual access points to the role of "dumb" transceivers. Outdoor applications may use mesh topologies. -
USB Drive
A USB flash drive is a data storage device that consists of flash memory with an integrated Universal Serial Bus (USB) interface. USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk. Most weigh less than 30 g.[1] As of September 2011 drives of 256 gigabytes (GB) are available,[2] and storage capacities as large as 2 terabytes (TB) are planned,[3] with steady improvements in size and price per capacity expected. Some allow up to 100,000 write/er -
Distance Records
Distance records (using non-standard devices) include 382 km (237 mi) in June 2007, held by Ermanno Pietrosemoli and EsLaRed of Venezuela, transferring about 3 MB of data between the mountain-tops of El Águila and Platillon.[44][45] The Swedish Space Agency transferred data 420 km (260 mi), using 6 watt amplifiers to reach an overhead stratospheric balloon.[46] -
Embedded Systems
Increasingly in the last few years (particularly as of 2007), embedded Wi-Fi modules have become available that incorporate a real-time operating system and provide a simple means of wirelessly enabling any device which has and communicates via a serial port.[47] This allows the design of simple monitoring devices. An example is a portable ECG device monitoring a patient at home. This Wi-Fi-enabled device can communicate via the Internet.[48] These Wi-Fi modules are designed by OEMs so that imp -
Wifi Health Issues
A small percentage of Wi-Fi users have reported adverse health issues after repeat exposure and use of Wi-Fi,[57] though there has been no publication of any effects being observable in double-blind studies. A review of studies involving 725 people that claimed electromagnetic hypersensitivity found no evidence for their claims.[58] The ubiquity of Wi-Fi has led to calls for more research into the effects of "electronic smog".[59] One study speculated that "laptops (Wi-Fi mode) on the lap near
