1. FDDI (Fiber Distributed Data Interface)
It is high performance fiber optic token ring network. IT is a standard for data transmission in a local area network. It is used with high bandwidth. FDDI provides a 100 Mbit/s optical standard for data transmission in local area network that can extend in range up to 200 kilometers (120 mi)FDDI is implemented without hubs, although you can use devices called concentrator to perform a similar function.
Short for Facsimile and sometimes called telecopying or telefax. It is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy.
Software that usually runs on the proxy server of an organization, and controls the flow of incoming and outgoing messages from within an organization for providing better security to the organization.Firewalls can be implemented as both hardware and software, or a combination of both. Network firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
Software that is substituted for hardware and stored in read-only memory (ROM).Firmware is a software program or set of instructions programmed on a hardware device. It provides the necessary instructions for how the device communicates with the other computer hardware.
5. FDM (Frequency Division Multiplexing)
A method to concurrently transmit data between several transmitters and receivers over a single transmission medium. It divides the available bandwidth of a physical medium into smaller, disjoint, logical bandwidths, and uses each of the component bandwidth as a separate communication line (channel).
6. Floppy Disk
A magnetic disk which is used to store data. They come in 3.5 and 5.25 inch diameter variants. Floppy disks are often used to transfer files from one PC to another or to Backup important files.
1. GUI (Graphical user interface) operating system
Microsoft introduced OS/2 operating systems. Windows operating system has a very user friendly interface. Windows 3.1 was the first popular version of Windows operating system. Later on Windows 95, Windows 98, Windows 2000, Windows XP, Windows NT, Windows Vista , Windows 7 and Windows 8 came into the market. Mouse is used for clicks and selecting various items in a GUI.
2. GIGO (Garbage-In-Garbage-Out)
It Refers to computer errors caused due to incorrect input data, or unreliable programs.
- A computer that is connected to the Internet by using a dedicated (leased) telephone line and is used to provide Internet connectivity to other computers via it.
- An internetworking tool that is used to interconnect
4. Gray scales
Number of shades of a color that can be presented on a monochrome (black and white) monitor’s screen, or on a monochrome printer’s output.
