- 3. The procedure in which the System Unit loads its operating system into its main memory (primary storage) from its non-volatile storage (secondary storage) by following the instructions within the “Read Only Memory”.
- 5. a “a binary term”; it is the smallest unit of information which can be read by a computer. It is 8 bits.
- 7. All the physical parts of the computer (any part that could be touched in real life by the human hand) (not including applications which go under software)
- 9. A term which was contracted from the words “binary digit” by taking the first letter of binary and the last two letters of digit. (though not very important). The smallest unit of data, a binary digit. A bit can either as be a 0 or a 1 as it is after all a single binary digit.
- 13. a private network for means of communicating (internally) usually belonging to a specific business
- 15. stands for Post-Office Protocol is a protocol which allows a computer to receive emails from the server (POP server)
- 17. The main directory which contains all the other “sub”- directories
- 18. A group of files, logically organized, stored under a single name. (Many of my directories can be found by using file explorer)
- 20. a computer program that controls the access abilities for a resource or service
- 21. Means of long distance communication via cable, telegraph, telephone, or broadcasting
- 23. a device with an IP address that can be communicated with through a network
- 24. devices Devices of a computer which convey information back to the user (such as the monitor)
- 26. The commonly used term for “electronic mail”. This is done by various people registered on the same network. One types up a message targeted for another on the same network (the recipient) and when the “e-mail” is sent, the messages are distributed.
- 30. messaging a way of communicating where the people communicating can see what the others type within a few nanoseconds or milliseconds
- 32. a standardized method procedure of exchanging data (gopher, newsgroup, telnet)
- 33. storage The storage that is temporary. This includes the RAM. It is really fast and helps in booting up the computer.
- 34. Any device that is part of the computer including both the input and output devices. Any device that is closely linked with the main parts of the computer the RAM, ROM and CPU.
- 36. groups of the same types of units (information) a string of characters, a string of bits, a string of decimal numbers
- 37. 2^20 bytes (not 10^6 bytes)
- 39. a length of strong cord made by placing an insulator (plastic usually) over various wires (of circular diameter) that is used for transfers data (usually stored as binary bytes) from peripherals the power source to the computer and vice versa, as well as connecting to a network via devices that have “IP” addresses
- 41. device which takes and sends packets from one network to another (usually one LAN to another LAN)
- 42. An output device which displays information to us. It shows us pictures and all of the information that the computer gives us as words, pictures (and all the media) through various electrons firing with phosphorous
- 44. largest publicly used internet
- 45. a system or a computer’s program that wants access to or can gain data information that is on a server or a “data protocol”. The client does not really need to be on the same computer as the server as they may be connected over by a network.
- 46. a connection between several devices (more than 1) which have an IP address which can transmit and receive (sharing) data
Down
- 1. Instructions telling the computer the process of a task and the time the task is to be done. These instructions are written in a language in which the computer is able to comprehend, which in sum is called a program. (the whole language)
- 2. Although generally confused to be known as 10^9 bytes, accurately, 2^30 bytes.
- 4. Internet (a specific internet network, via a password) without the need of wires and to communicate in such way without wires as well
- 6. A single letter, digit space, or special symbol. (@, , a,1 are all characters)
- 8. a method of connecting several computers to make a LAN (Local Area Network) in order to handle how the information is passed on.
- 10. Any form of data that have meaning words, pictures, sounds,
- 11. unit A part of the whole “computer” which contains the key parts of the computer. The system unit is usually a metal box holding amongst other parts the CPU, RAM, ROM, connecting cables and power source. (motherboard contains the CPU, RAM and ROM). The system unit contains most of the parts that store and analyze the information put into or given to a computer.
- 12. collection of data which is part of a larger item (such as an e-mail). Packets are made up of sender’s network address, and a recipient’s network address
- 14. (of information) The procedure of taking in the information give to the computer and analyzing it. Manipulating the data given to the computer such as converting raw data to machine readable form, reading the data via the lasers, on the disk are all processing of information.
- 16. system Groups of programs which tell the system unit how to perform some tasks taking in the information that we give to the computer through its input devices, showing data through the output devices, launching applications (application software) and executing other such directions commands instructions
- 19. paradigm a means of considering the association between a network device which is willing to provide and gain access to certain privileges (services)
- 22. devices Devices used to put information into the computer keyboard, mouse, disc drives)
- 25. stands for Transmission Control Protocol is the division of a file into packets and transferring of such divisions by the internet to be received by another layer which joins all packets together to create the original creation. (Gateways decide in which direction to send the message).
- 27. “a “modulator-demodulator” which enables communication between analogue and digital devices (output signals from computer modulated and input signals are demodulated)
- 28. media an audio or video file that is first compressed then shared over the Internet by usage of protocol which enables the receiver to play it before the transmission is fully loaded (full transmission received) ← such as for live stream
- 29. Although, mistakenly thought of as a 1000 bytes, it is 2^10 or 1024 bytes.
- 31. Information that is logically contained under a single name.
- 35. An interconnection point used to connect parts of a local area network
- 38. a private network by an enterprise that can be somewhat accessed by “other” yet authorized users due to the businesses having the want to transfer information securely
- 39. A electronic device with many parts to it that can process and output information. (System unit, monitor)
- 40. code A way for encoding data using only the digits 0 and 1. Binary code can encode text, images, sounds, and programs, and any other data!
- 43. The name given by Apple to the IEEE 1394 High Speed Serial Bus; it is called i. LINK by Sony and Lynx by Texas Instruments.
