- 1Open Source Softwaresoftware whose source code is available for modification or enhancement by anyone.
- 2Proprietary Softwaresoftware that is owned by an individual or a company (usually the one that developed it). There are almost always major restrictions on its use, and its source code is almost always kept secret.
- 3DMSDiary Management Software
- 4Firewallprotect (a network or system) from unauthorized access with a firewall.
"a firewalled network" - 5SSIDSSID is a case sensitive, 32 alphanumeric character unique identifier attached to the header of packets sent over a wireless local-area network (WLAN) that acts as a password when a mobile device tries to connect to the basic service set
- 6WEPWired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b, that is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN.
- 7WPAWi-Fi Protected Access (WPA) is a security standard for users of computers equipped with Wi-Fi wireless connection. It is an improvement on and is expected to replace the original Wi-Fi security standard, Wired Equivalent Privacy (WEP).
- 8WPA2Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols and security certification programs developed by the Wi-Fi Alliance to secure wireless computer networks.
- 9AESThe Advanced Encryption Standard or AES is a symmetric block cipher used by the U.S. government to protect classified information and is implemented in software and hardware throughout the world to encrypt sensitive data.
- 10Blueootha standard for the short-range wireless interconnection of mobile phones, computers, and other electronic devices.
- 11Bandwidtha range of frequencies within a given band, in particular that used for transmitting a signal.
- 12Wi-Fia facility allowing computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area.
- 13RouterA 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.
- 14Modema combined device for modulation and demodulation, for example, between the digital data of a computer and the analogue signal of a telephone line.
- 15Remote Workingwhen people do their work at home, using a computer that is connected to the computer system in an office
- 16Optical StorageOptical storage devices save data as patterns of dots that can be read using light. A laser beam is the usual light source.
- 17Magnetic StorageMagnetic storage is one of the most affordable ways to store large amounts of data and has been implemented using magnetic tape, floppy disks and hard disk drives.
- 18CCTVCCTV (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.
- 19Key Loggera computer program that records every keystroke made by a computer user, especially in order to gain fraudulent access to passwords and other confidential information.
- 20Etherneta 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.
- 21User IDAlso called login name, logon name, sign-in name, sign-on name. a unique sequence of characters used to identify a user and allow access to a computer system, computer network, or online account.
- 22DoSDOS (Disk Operating System) was the first widely-installed operating system for personal computers. (Earlier, the same name had been used for an IBM operating system for a line of business computers.)
- 23Data Capture FormBefore setting up a database the data must be collected. This can be done using a data capture form.
- 24EncryptionEncryption 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.
- 25GUIIn computing, a graphical user interface 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 labels or text navigation.
- 26Foruma meeting or medium where ideas and views on a particular issue can be exchanged.
- 27Phishingthe fraudulent practice of sending emails purporting to be from reputable companies in order to induce individuals to reveal personal information, such as passwords and credit card numbers, online.
- 28Radio Buttons(in a graphical display) an icon representing one of a set of options, only one of which can be selected at any time, e.g. male female.
- 29Passworda string of characters that allows access to a computer, interface, or system.
- 30Data UserA data user is someone who controls the collection, holding, processing, or the use of the data.
- 31Information CommissionerThe 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.
- 32Peer to peer file transferPeer-to-peer file sharing is the distribution and sharing of digital media using peer-to-peer (P2P) networking technology.
- 33NFCNear 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.
