INFORMATİON TECHNOLOGİES

Software is a set of instructions that enables the user to interact with a computer, its hardware, or perform tasks. Software is designed to enable a computer to perform a well-defined function.

A device driver is a system software that operates or controls a particular hardware device (e.g., graphic card, printer, scanner, etc.) that is connected to a computer. It allows a computer to communicate with these internal or external peripheral devices.

Firmware is a small and permanent software programmed into a read-only memory.

An operating system is a program that manages the computer hardware. It provides an container environment in which other programs can work.

Booting is the process of starting or restarting a computer.

The correct answer is A.

System Software is 

The correct answer is B.

Application Software is

The most prominent characteristics of Operating Systems can be summarized as follows:

• Memory Management

• Processor Management

• File Management

• Device Management

• Protection and Security

The correct answer is E.

The main objectives of the operating system can be summarized as follows:

• Enables the users to use computer in a convenient and efficient manner

• Hides complexity of the hardware resources from the users

• Acts as an intermediary between the computer hardware and its users.

• Manages the resources of a computer system

• To keep track of who is using which resource, granting resource requests, according for resource using and mediating conflicting requests from different programs and users

• Provides efficient and fair sharing of resources among users and programs.

The correct answer is E.

Text related tasks such as composing, editing, formatting, and printing of text documents are carried out by word processor. Furthermore, word processing software allows users to

• change margins

• insert footnotes

• find and replace terms

• place a header and footer at the top and the bottom of a page

• use different fonts (character design), font size (character scale), and font style (character appearance such as bold, italic and underline).

Another useful feature of word processors is the spell checking utility. This feature automatically detects misspelled words and underlines them. Furthermore, it suggests a couple of corrected versions by saying “did you mean?” As it can be observed from Figure 2.6, the functionality offers several possible candidates for a mistyped word.

Word processor tools allows you to save your document as a PDF. This is usually done using the export menu.

The correct answer is D.

A spreadsheet programs, such as Microsoft excel, is used for reviewing and editing spreadsheets. Spreadsheets can be thought of tables filled with data in the form of numbers, dates, strings etc. Spreadsheet programs are powerful tools for getting meaning out of raw data. It helps to discovers trends and patterns using data bars, spark lines, color coding, and icons. Even helps summarize and illustrate insights by charts and graphs. 

The correct answer is B.

Software is a set of instructions that enables the user to interact with a computer, its hardware, or perform tasks. Software is designed to enable a computer to perform a well-defined function.

The correct answer is C.

Application software may consist of a single program, such as a Microsoft’s notepad or MacOS’sTextEdit for writing and editing simple text. It may also consist of a collection of programs, often called a software package, which work together to accomplish a particular task, such as an office suite package.

In information technology, application software is a computer program designed to help people perform an activity.

An application software differs from an operating system (which runs a computer), a utility (which performs maintenance or general-purpose chores), and a programming tool (with which computer programs are created).

The correct answer is D.

The management and scheduling of processes are handled by the operating system.Operating system optimally decides which processes will use the CPU and how long. It tries to take full advantage of the CPU. OS schedules and coordinates running processes so that resources are not wasted.

The correct answer is D.

In information technology, application software is a computer program designed to help people perform an activity.An application software differs from an operating system (which runs a computer), a utility (which performs maintenance or general-purpose chores), and a programming tool (with which computer programs are created).Firmware is a small and permanent software programmed into a read-only memory. The correct answer is B.

System software is more difficult to design than application software. System software is smaller in size; whereas application software requires large space to store. Application software is more interactive than system software. System software is difficult to manipulate. System software is generally written in low-level language while application software is generally written in high-level . The correct answer is D.

Linux is an operating system. Microsoft Edge and Google Chrome are web browsers. Adobe Acrobat Reader is a word processor. However, Microsoft Excel is the most commonly used spreadsheet program. The correct answer is C.

Internet Relay Chat (IRC) is a protocol that facilitates synchronous communication in the form of text. It allows several users to chat each other simultaneously. IRC clients (also referred to as chat clients) are computer programs that allows to connect to a chatroom (also called IRC channel), which allows users to chat about a topic of interest via the computer. For example, it is a chatroom on IRC network where users can ask questions and receive answers from other users regarding usage of an open source library. The correct answer is C.

A typical office suite includes/bundles all the software tools/packages required to get office work (collaboration, editing tools, and design) done quickly and efficiently. In general, an office suite includes the following application software: • A word processor • A spreadsheet application • A presentation software. The correct answer is B.

The classification of computer software is given in the figure below. According to this figure, the correct answer is A.

The three mainstream operating system are : Microsoft Windows, MacOs and Linux. The correct answer is E.

iOs and Android are not desktop operating sytems. Among the other three, Microsoft Windows has the biggest share in the market with 91.66%. The correct answer is A.

A browser is a software to connect to the Internet (WorldWideWeb) and displayWeb pages. Several browser implementations, such as Firefox, Safari and Microsoft Edge are listed in Table 2.5. Each Web page is distinguished and accessed by its Uniform Resource Locator (URL), which is a human-memorable address used to locate resources on the Internet.The correct answer is C.
