- 1WANWide Area Network that covers a broad area
- 2LANLocal area network that covers a small band area
- 3Output DeviceAn output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form.
- 4Input DeviceDevices that input data into the computer eg keyboard
- 5Storage DeviceA data storage device is a device for recording (storing) information (data). Recording can be done using virtually any form of energy, spanning from manual muscle power in handwriting, to acoustic vibrations in phonographic recording, to electromagnetic energy modulating magnetic tape and optical discs.
- 6Input DeviceDevices that input data into the computer eg keyboard
- 7SSDA solid state hard drive with no moving parts.
- 8FirewireIEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple, who called it FireWire. The 1394 interface is comparable to USB though USB has more market share.
- 9GPSGlobal positioning system that helps find where people are.
- 10IP addressInternet protocol
- 11RFIDRadio frequency identification uses radio waves used to read and capture information stored on a tag attached to an object
- 12SD cardAn 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.
- 13Security KeyA password for a WLAN.
- 14VoIPVoice over Internet Protocol is a category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls by sending voice data in packets using IP rather than by traditional circuit transmissions of the PSTN.
- 15CDCompact disc (CD) is a digital optical disc data storage format. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM).
- 16DVDA type of compact disc able to store large amounts of data, especially high-resolution audiovisual material.
- 17Cloud StorageCloud storage is a model of data storage where the digital data is stored in logical pools, the physical storage spans multiple servers (and often locations), and the physical environment is typically owned and managed by a hosting company.
- 18USBUniversal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.
- 19Open source softwareSoftware that can be downloaded by anyone for free, no one owns it.
- 20Proprietary SoftwareSoftware owned by someone, if someone wants to download it they need to pay eg Microsoft Word
- 21DMSDiary Management software is when you manage your diary through calenders, notifications and other ways. Typically found on smart phones.
- 22Firewalla system designed to protect an computer system from unauthorized entry Ie. by a virus.
- 23SSIDSSID is the name of a wi-fi network that is unique.
- 24WEP,WPA,WPa2,AESThese are security systems for wireless networks
- 25BluetoothWhen two devices can connect to each other such as a phone to a speaker to play music.
- 26BandwidthIn computing, bandwidth is the bit-rate of available or consumed information capacity expressed typically in metric multiples of bits per second. Variously, bandwidth may be characterized as network bandwidth, data bandwidth, or digital bandwidth.
- 27WI-FIA system where devices such as smartphones and computers can connect to the interent
- 28RouterA router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect.
Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols such as ICMP to communicate with each other and configure the best route between any two hosts.
Very little filtering of data is done through routers - 29Modema combined device for modulation and demodulation, for example, between the digital data of a computer and the analogue signal of a telephone line.
- 30Remote WorkingWhen a person works from home using a laptop or a smartphone.
- 31Optical StorageOptical storage is the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light precisely focused on a spinning disc.
- 32Magnetic StorageMagnetic storage (or magnetic recording) is the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetization in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads.
- 33CCTVCCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere.
- 34Key LoggerA keylogger is a type of surveillance software (considered to be either software or spyware) that has the capability to record every keystroke you make to a log file, usually encrypted. A keylogger recorder can record instant messages, e-mail, and any information you type at any time using your keyboard. Can be used top get passwords.
- 35Etherneta system for connecting a number of computer systems to form a local area network, with protocols to control the passing of information and to avoid simultaneous transmission by two or more systems.
- 36User IDA User ID is the code used by a User to identify himself when he logs into a system and starts a Login Session. It is used by the system to uniquely identitfy this User. A User ID is one-half of a set of Credentials.
- 37DoSThe term DOS can refer to any operating system, but it is most often used as a shorthand for MS-DOS (Microsoft disk operating system). Originally developed by Microsoft for IBM, MS-DOS was the standard operating system for IBM-compatible personal computers.
- 38Data Capture FormA way of inputting data through the internet. Can be used to show age, name, gender, occupation etc.
- 39EncryptionEncryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text ; encrypted data is referred to as cipher text.
- 40GUIIn computing, a graphical user interface (GUI, sometimes pronounced "gooey" or "gee-you-eye") is a type of interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command ...
- 41ForumAn online discussion where people can post their views.
- 42PhishingPhishing is the attempt to acquire sensitive information such as usernames, passwords, and credit card details (and sometimes, indirectly, money) by masquerading as a trustworthy entity in an electronic communication.
- 43Radio ButtonAn icon representing one of a set of options, only one of which can be selected at any time.
- 44PasswordA string of characters that allows access to a computer, interface, or system.
- 45Information Commisionerhe role of Information Commissioner differs from nation to nation. Most commonly it is a title given to a government regulator in the fields of freedom of information and the protection of personal data in the widest sense. The office often functions as a specialist ombudsman service.
- 46Peer to Peer File SharingPeer-to-peer file sharing is the distribution and sharing of digital media using peer-to-peer (P2P) networking technology.
- 47NFCNear field communication (NFC) is a set of ideas and technology that enables smartphones and other devices to establish radio communication with each other by touching them together or bringing them into proximity, typically a distance of 10 cm (3.9 in) or less.
