CIT 101 - Class Test

Computer operators communicates with the computer’s CPU by using various input devices to enter data, run programs, or give commands to the CPU. These devices include the following: Keyboard, Mouse, Scanners, Modems, Light pen, Voice Recognition, Joysticks. All these are used to enter data or runs program into the computer. Page 7

A keyboard is used to enter data into the computer. It is an input device that allows users to type and input information, commands, and instructions into the computer system. It consists of a set of keys, including letters, numbers, symbols, and function keys, that can be pressed by the user's fingers to input data. The other options listed, such as typewriter and printer, are not typically used to directly enter data into a computer.

A spreadsheet consists of information written in tabular form; in other words, rows and/or columns of figures and/or text, Example is MS Excel, Lotus 1,2,3 etc Page 86

A computer is an electronic device for storing and processing data according to instructions given to it in a variable program . Yes Computer is a machine but not only that, also it is an electronic machine but that definition is not complete.

A directory or folder is nothing more than a location on a disk used for storing information about files. Directory is also called Folders. Page 38

Until it is saved, a workbook exists only in computer memory, which is a temporary storage place Page 97

Computer can only store and process data/information/instructions. Page 3

The correct answer is WWW, which stands for World Wide Web. The World Wide Web refers to the linking up of the world's LANs, MANs, and WANs to form a web of networks that cover the earth. It is a system of interconnected documents and other resources, linked by hyperlinks and URLs, that can be accessed via the internet. The World Wide Web allows users to access and share information globally, making it an essential component of the internet.

Computer operators communicates with the computer’s CPU by using various input devices to enter data, run programs, or give commands to the CPU. Page 7
Other examples include - Mouse, Modem, Voice, Scanners etc

Yes its TRUE, a modern computer is basically designed in electronic device that can respond to commands or instructions... Page 3

PowerPoint is an application program specifically designed for creating and delivering presentations. It provides users with a wide range of tools and features to create visually appealing slideshows, including the ability to add text, images, charts, animations, and multimedia elements. PowerPoint is widely used in various settings, such as business meetings, educational presentations, and conferences, to effectively communicate information and engage the audience. Therefore, the correct answer is "application program for presentation."

The correct answer is "Operating System" or "OS". The operating system is the software responsible for controlling the allocation and usage of hardware resources. It manages the computer's memory, processes, input/output devices, and other system resources, ensuring that they are utilized efficiently and effectively. The operating system acts as an intermediary between the hardware and the user, providing a user-friendly interface and facilitating the execution of applications and tasks.

GUI = Graphical User Interface

The Automatic Spell Check feature informs you of spelling errors as you type, It can be enabled or disabled by choosing Tools, Options…and selecting the Spelling & Grammar tab. Page 82

A terminal is a data input-output device, usually made up of a monitor (display), keyboard, mouse, or touch screen.

Computer machinery refers to the physical components of a computer system, such as the central processing unit (CPU), memory, storage devices, and input/output devices. These physical components are collectively known as hardware. Utility software, operating systems, and other software programs are not considered part of the computer machinery, as they are intangible and do not involve physical components. Therefore, the correct answer is hardware.

An interconnected set of two or more computers with data communication devices is commonly referred to as a computer network. This network allows the computers to communicate and share resources, such as files and printers, with each other. It enables users to access and exchange information, collaborate, and perform various tasks efficiently. A computer network can be wired or wireless and can range from a small local area network (LAN) within a single building to a wide area network (WAN) connecting multiple locations across the globe.

The correct answer is "none of the above" because "www" stands for "World Wide Web" and none of the given options match this acronym.

CPU stands for Central Processing Unit

When using a mouse, one is able to move the cursor around the screen with speed and simplicity. Most have two buttons, which will execute commands according to an application’s control instructions

By default, Word is in insert mode; as you type, text to the right of the insertion point is pushed to the right. Page 66

Text files can be created and modified with the aid of a special program called an editor (page 65),

An editor is a program used to create text files or make changes to 

Modem stands for Modulation Demodulation. A modem is a device that modulates (converts) digital signals from a computer into analog signals that can be transmitted over telephone lines. It also demodulates (converts) analog signals received from the telephone lines back into digital signals that the computer can understand. The term "modulation demodulation" accurately describes the main function of a modem, which is to modulate and demodulate signals for communication purposes.

Word processing is the use of computers to create, revise and save documents for printing and future retrieval (Page 58). It is a little bits different from Notepad and Wordpad.

The final step in the production of a document is printing. Page 83

Excel is a software application that provides an “electronic spreadsheet,” or worksheet environment Page 88

The menu bar displays the primary commands of the relevant application. Page 44

There are four alignment options, namely | Left Alignment | Center Alignment | Right Alignment | Justified | Page 78

The Windows environment provides a temporary storage area called the Clipboard for those times when you move or copy text Page 69

Booting refers to the process of starting up a computer system. It involves loading the operating system and initializing the necessary hardware components. When a system is switched on, the booting process begins, allowing the computer to become operational. Therefore, the correct answer is "switching on the system."

The part lablelled D is the toggle switch on

Lines of text are aligned along both the left and right indents. Word adjusts the spacing between words so that they stretch from left indent to right indent. Page 79

“Formatting” refers to the appearance or text, not the text itself. You can change the appearance of text by changing its attributes, indentation and line spacing. In order to change the appearance of existing text, the text has to be selected.. Page 159-160

Word gives you the option of turning off insert mode and turning on overtype mode. Instead of pushing text to the right as you type, overtype mode replaces existing text one character at a time. Page 66

Some Formatting buttons are toggles, that is, the same button is used to turn a formatting feature “on” and “off” Page 75

Word is a WYSIWYG (what-you-see-is-what-you-get) word processor Page 55

FORTRAN stands for Formula Translator. It is a programming language that was developed in the 1950s and is widely used for scientific and engineering applications. The name "Formula Translator" reflects its original purpose of translating mathematical formulas into machine code. FORTRAN is known for its efficiency in numerical calculations and its ability to handle complex mathematical operations. Despite being an older language, FORTRAN is still used today in various industries where high-performance computing is required.

An Excel file, contains what is called a workbook and this workbook contains files called worksheets. (Page 88) By default, Excel workbook contains 3 worksheets namely, Sheet1, Sheet2 and Sheet3 (Page 90)
