- 3. is a precise sequence of instructions for successfully carrying out a task. It will be written in everyday language but the steps might be capable of translation into a programming language. There might be a number of workable algorithms for a task but not all will be as efficient as the others.
- 7. Decomposition in computer science, also known as factoring, is breaking a complex problem or system into parts that are easier to conceive, understand, program, and maintain.
- 9. is an accurate representation of a real life activity. We use simulations when something is either too dangerous or too expensive to do for real.
- 10. In computer programming, a loop is a sequence of instruction s that is continually repeated until a certain condition is reached. Typically, a certain process is done, such as getting an item of data and changing it, and then some condition is checked such as whether a counter has reached a prescribed number.
- 13. it can take a variety of forms, from commands you enter from the keyboard to data from another computer or device. A device that feeds data into a computer, such as a keyboard or mouse, is called an input device. (v.) The act of entering data into a computer.
- 14. One of the three basic logic structures in computer programming. The other two logic structures are selection and loop. In a sequence structure, an action, or event, leads to the next ordered action in a predetermined order.
- 15. is a computer’s way of evaluating something and saying that if it has a particular attribute it will do one thing, otherwise it’ll do something else.
- 17. Data is defined as facts or figures, or information that's stored in or used by a computer. An example of data is information collected for a research paper. An example of data is an email.
- 19. A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms.
- 20. Conceal a miniature microphone in (a room or telephone) in order to monitor or record someone's conversations.

- 1. it has been employed for many years, mainly in high-performance computing
- 2. is a subset of a program that does a particular thing. It can be called up by the main program at any time to save having to type it out again and again
- 4. In computer science, conditional statements, conditional expressions and conditional constructs are features of a programming language, which perform different computations or actions depending on whether a programmer-specified Boolean condition evaluates to true or false.
- 5. is what data becomes after they are organised. It might be reported in words or a chart of some sort.
- 6. can mean either print some output (words, numbers or images) on a screen or on paper through a printer. Nowadays it is even possible to print in 3D
- 8. In computers, debugging is the process of locating and fixing or bypassing bugs (errors) in computer program code or the engineering of a hardware device. To debug a program or hardware device is to start with a problem, isolate the source of the problem, and then fix it.
- 11. A computer operator is the person responsible for monitoring and controlling computer systems especially mainframe computer systems in a company or organization.
- 12. A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function, and typically executes the program's instructions in a central processing unit.
- 16. An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in common use today.
- 18. An 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.
