A modem is a device that enables the connection between a computer and an internet service. It acts as a translator, converting digital signals from the computer into analog signals that can be transmitted over telephone lines or cable lines, and vice versa. By connecting the modem to the computer, users can access the internet and communicate with other devices or servers.

Mozilla Firefox is a web browser, not an email client. While Microsoft Outlook 2003, Windows Live Mail, and Outlook Express 6 are all email clients that allow users to send, receive, and manage emails, Mozilla Firefox is primarily used for browsing the internet and does not have built-in email functionality.

Thunderbird is not an internet browser, but rather an email client developed by Mozilla. It is used for managing emails, contacts, and calendars, but does not have the capability to browse the internet. Safari, Firefox, and Opera, on the other hand, are all popular internet browsers used to access and navigate websites on the internet.

The CPU, or Central Processing Unit, is often referred to as the brain of the computer. It is responsible for executing instructions, performing calculations, and processing information. The CPU carries out all the necessary operations required for the computer to function, including moving data between different components and performing complex calculations. It is a crucial component that determines the speed and performance of the computer.

MS-Word is not an operating system. It is a word processing software developed by Microsoft. Operating systems, on the other hand, are the software that manage computer hardware and software resources and provide services for computer programs. DOS, Windows, and LINUX are examples of operating systems. MS-Word, although it can be installed and run on various operating systems, is not an operating system itself.

A wireless router is a device that allows multiple devices to connect to the internet wirelessly. It acts as a central hub for a network, transmitting data between devices and the internet. This device is commonly used in homes and offices to provide internet access to laptops, smartphones, and other wireless devices. It differs from a modem, which is responsible for connecting to the internet service provider, and a video card and motherboard, which are components of a computer system.

An IP address is a unique numerical identifier assigned to each device connected to a network. It consists of four parts separated by dots and is used to identify and communicate with devices on the internet. This address allows data packets to be sent and received between different systems, enabling the transfer of information across the network.

The correct answer is 1024KB because in the binary system, 1 kilobyte (KB) is equal to 1024 bytes. Therefore, 1024KB is equal to 1024 multiplied by 1024 bytes, which is equivalent to 1 megabyte (MB).

Malware refers to software that is specifically created to infiltrate or harm a computer system without the knowledge or consent of the owner. It is different from antivirus software, which is designed to protect the operating system from viruses. Microsoft Arithmetic LAN software, on the other hand, is a specific program developed by Microsoft for mathematical calculations. Therefore, the correct answer is that malware is software designed to infiltrate or damage a computer system without the owner's informed consent.

Ping is a computer network tool used to test the reachability of a particular host across an IP network. It is commonly used to check if a host is online and responsive. Ping sends a small packet of data to the target host and waits for a response. If a response is received, it indicates that the host is reachable. Ping can also be used to perform a self-test of the Network Interface Card (NIC) of the computer, ensuring that it is functioning properly.

The correct answer explains that the term "download" refers to the process of receiving data on your PC. This can include various activities such as viewing webpages, receiving emails, watching videos, getting movies, getting music, and downloading email attachments. It does not specify the exact size of the data being received or the method of transmission, but rather focuses on the action of receiving data.

The keyboard is not an output device because it is used for inputting data into a computer system, rather than displaying or producing output. Output devices, on the other hand, are used to display or produce information from a computer system, such as printers for producing hard copies of documents, monitors for displaying visual output, and modems for transmitting data over a network.

A network interface card (NIC) is a computer component that allows a computer to connect to a network. It is responsible for providing the necessary hardware and software to enable communication between the computer and the network. The NIC is typically inserted into an expansion slot on the motherboard and has ports for connecting network cables. It plays a crucial role in facilitating data transmission over a network, allowing the computer to send and receive data to and from other devices on the network.

Megabits per second is the correct answer because it is a unit of measurement commonly used to express the speed of data transfer over a network. Megabits per second refers to the number of millions of bits that can be transmitted in one second. This unit is used to measure the bandwidth or capacity of a network connection, indicating how quickly data can be transmitted from one point to another.

Bandwidth refers to the measurement of how much information can be carried in a given time period, typically a second, over a wired or wireless communications link. It is not related to the speed of data transfer from the server to the client or a unit of information or computer storage equal to one billion bytes. Therefore, the correct answer is the third option.

The correct answer is CPU. CPU stands for Central Processing Unit, which is the main component of a computer responsible for executing instructions and performing calculations. It is often referred to as the "brain" of the computer as it carries out all the processing tasks. RAM, Hard Disk, and Motherboard are other computer components, but they do not perform the same functions as the CPU.

The correct answer is "It is used to store large amounts of data in a computer system, data is retained on this device even when the computer is turned off." This answer accurately describes the function of a storage device, which is to store data in a computer system. It also mentions that the data is retained even when the computer is turned off, indicating that it is a non-volatile storage device.

The correct answer is the US Department of Defense. The internet was originally developed by the US Department of Defense in the late 1960s as a means of communication and data sharing between different computers. It was initially known as ARPANET and later evolved into the internet that we use today. Bill Gates, Steve Jobs, and Albert Einstein are not directly associated with the invention of the internet.

The correct answer is chassis. A chassis is a computer component that refers to the physical structure or framework that houses and protects all the internal components of a computer, such as the motherboard, CPU, hard drive, and other peripherals. It provides structural support and helps in organizing and connecting various components together.

The correct answer is untitled.jpg, untitled.bmp, untitled.tiff. These three files have the file extensions .jpg, .bmp, and .tiff, which are commonly used for graphics files. The other files, untitled.nfo and untitled.ogg, have different file extensions and are not typically used for graphics files.

The term "Operating System" is best defined as all of the above options. An operating system is a software that allows computer users to run applications with the hardware of a specific system. It also acts as a master control program that manages a computer's internal functions and provides a means of control to the computer's operations and file system. Additionally, an operating system manages the hardware and software interface of a computer. Therefore, all of the given options accurately describe the term "Operating System".

Windows ME, also known as Windows Millennium Edition, was the successor to Windows 98. It was released by Microsoft in the year 2000. Windows ME was designed to be more user-friendly and included several new features such as System Restore, Windows Movie Maker, and Windows Media Player 7. Despite its improvements, Windows ME was not as stable or popular as its predecessor, and it was eventually replaced by Windows XP in 2001.
