Electronic Document Preparation And Management

A hacker is someone who gains unauthorized access to a computer system. This means they are able to enter a computer or network without permission or proper authorization.

Barcodes are indeed found on most items in the supermarket. They are used for efficient and accurate product identification and pricing at the checkout counter. Barcodes contain information such as the product's manufacturer, item number, and price. By scanning the barcode, the cashier can quickly retrieve this information and process the transaction. Therefore, it is true that barcodes are commonly found on items in the supermarket.

The Recycle Bin is a storage location in Windows where deleted files are temporarily stored before they are permanently deleted. It allows users to easily recover accidentally deleted files or restore files that were deleted by mistake. The other options listed, such as Internet Explorer, Outlook Express, and My Documents, do not have the functionality to store deleted files for later use.

When you reboot a computer, you restart it by shutting it down and then turning it back on. This process allows the computer to refresh its system and start from a clean state, which can help resolve certain issues or improve performance. Rebooting is a common troubleshooting step and is often recommended when experiencing software glitches or system slowdowns. Therefore, the statement "When you reboot a computer you restart it" is true.

Programmes such as games and Microsoft Word can be classified as software because they are computer programs that provide instructions for the computer to perform specific tasks. Software refers to the programs and data that are stored on a computer's hardware and can be executed or run by the computer's processor. In this case, games and Microsoft Word are examples of software applications that can be installed and run on a computer system to perform specific functions, such as gaming or word processing.

Microsoft Word is not a component of the computer system because it is a software application that is installed on the computer system. Components of the computer system typically refer to the physical hardware such as the CPU, memory, storage devices, and input/output devices. Software, data, and hardware are all essential components of the computer system, but Microsoft Word is a specific software program that is used for word processing and is not considered a core component of the overall computer system.

A monitor is not an input device because it is used to display output from the computer, rather than to input data or commands. Input devices, on the other hand, are used to enter data or commands into the computer system. Examples of input devices include a mouse, keyboard, and scanner, all of which are used to input data or commands into the computer.

Input devices are used to get data and instructions into the computer for processing. These devices allow users to input data and commands into the computer system, which can then be processed and utilized by the computer. Examples of input devices include keyboards, mice, scanners, and microphones. These devices play a crucial role in enabling communication between the user and the computer, facilitating the transfer of information and instructions for further processing.

A folder or directory can contain files, folders, and programs. This means that it can hold various types of data and organizational structures within it. Therefore, the correct answer is "All of the above" as it encompasses all the possible contents of a folder or directory.

Data can be defined as raw material because it refers to unprocessed and unorganized facts and figures. Raw data is collected and then processed to convert it into meaningful information. Just like raw material is used to create finished products, raw data is used to generate insights and make informed decisions. Therefore, raw material is an appropriate term to describe data in its initial form before any processing or analysis is done.

The Central Processing Unit (CPU) is the main component of a computer system that performs all the processing and calculations. It consists of two main units, namely the Control Unit and the Arithmetic and Logic Unit (ALU).

The Control Unit is responsible for coordinating and controlling the operations of the CPU. It fetches instructions from memory, decodes them, and executes them by sending signals to other components of the computer.

The ALU, on the other hand, performs all the arithmetic and logical operations such as addition, subtraction, multiplication, division, and comparisons. It carries out calculations and logical decisions based on the instructions provided by the control unit.

Therefore, the correct answer is "Control Unit and Arithmetic and Logic Unit" as these two units are the essential components of the CPU.

LIME is able to provide service to its customers through the use of mainframe computers. Mainframe computers are large, powerful, and capable of handling large amounts of data and processing tasks simultaneously. This makes them ideal for supporting a large customer base and providing efficient and reliable service. Additionally, mainframe computers have high availability and reliability, ensuring that LIME can deliver uninterrupted service to its customers.

Input devices are responsible for capturing and converting data from external sources into a format that can be processed by a computer. However, they do not directly turn raw data into information. The conversion of raw data into meaningful information occurs through the processing and analysis of the data by the computer system. Therefore, the statement is false.

The statement is incorrect because while data is a part of information, it is not the same thing. Data refers to raw facts and figures, while information is data that has been processed, organized, and given context to make it meaningful and useful. Therefore, data and information are related but not interchangeable terms.
