This network allows for the exchange of data, information, and resources among the connected devices, enabling them to work together and enhance productivity. Therefore, the statement accurately describes the concept of a computer network.

Email, instant messaging, chat rooms, and videoconferencing are all methods of exchanging information and ideas between individuals or groups. These forms of communication allow for efficient and effective communication to take place through networks. Therefore, the correct answer is "communication".

WLAN stands for Wireless Local Area Network. It is a type of wireless network that allows devices to connect and communicate wirelessly within a limited area, such as a home, office, or campus. The other options, Wireless Large Area Network, Western Local Address Network, and World-Local Address Network, are incorrect and do not accurately represent the meaning of WLAN.

A Wide Area Network (WAN) is a network that covers a large geographical area and uses many types of communications channels. Unlike a Local Area Network (LAN) which is limited to a small area, a WAN can connect multiple LANs over a wide distance. WANs are typically used by organizations that have multiple branches or offices spread across different locations, allowing them to share resources and communicate efficiently.

A firewall is a security measure that can be implemented using hardware and/or software to restrict access to data on a network. It acts as a barrier between an internal network and external networks, filtering incoming and outgoing network traffic based on predetermined security rules. By monitoring and controlling network traffic, a firewall helps prevent unauthorized access, potential threats, and data breaches, ensuring the security and integrity of the network.

A LAN is only one type of network. Computers/devices need to be connected not just in an organisation. A wireless link is only one type of connection

Internet peer-to-peer networking enables users with the same networking software to exchange files directly from each other's hard disks. This means that users can share files with each other without the need for a central server. Instead, the files are transferred directly between the users' computers, allowing for faster and more efficient file sharing.

The correct answer is "all of the above" because to connect to the internet, you can use any of the mentioned options: dial-up connection, DSL connection, cable lines connection, satellite connection, or cellular or mobile data connection. Each of these options provides a different method of accessing the internet, allowing users to choose the most suitable option based on their location, availability, and personal preferences.

The option "SPIRAL" is not a type of network topology. Network topologies refer to the physical layout of a network, such as how devices are connected and communicate with each other. The other options listed - STAR, RING, BUS, and MESH - are all valid types of network topologies commonly used in computer networks. However, "SPIRAL" does not represent a recognized network topology.

A client is any component on a network that receives data from other components. This means that it is a device or software application that requests and receives information or services from a server or another client on the network. Clients can include computers, smartphones, tablets, or any other device that connects to a network and interacts with other components to access data or resources.

FTP stands for File Transfer Protocol. It is a standard network protocol used to transfer files from one host to another over a TCP-based network, such as the internet. FTP provides a simple and efficient way to upload, download, and manage files on a remote server. It is commonly used by web developers to transfer website files to a web server, and by individuals to transfer files between their personal devices and remote servers.

Fibre-optic cable is capable of the fastest rate of data transmission compared to the other options. This is because it uses light signals to transmit data, allowing for a higher bandwidth and faster transmission speeds. Twisted-pair cable and coaxial cable use electrical signals, which are slower in comparison. Bluetooth wireless transmission also has lower data transmission rates compared to fibre-optic cable.

A LAN (Local Area Network) enables users to share resources such as files, application programs, printers, and other software/hardware. This means that multiple users connected to the LAN can access and utilize these shared resources, making it easier to collaborate and work together efficiently. The other options mentioned, such as transfer of money via electronic funds transfer and public transportation, are not related to the capabilities of a LAN and are therefore not applicable.

The best solution for setting up a network in a building where drilling holes through walls is not possible would be to use a WAP (Wireless Access Point). This is because a WAP allows for wireless connectivity, eliminating the need for physical connections through walls. Ethernet Cat5e and fiber optic cables require drilling holes for installation, so they are not suitable in this scenario. Therefore, the correct answer is a WAP.

PAN = Personal Area Network

LAN = Local Area Network

MAN = Metropolitan Area Network

WAN = Wide Area Network

Switches on a network refer to hardware devices that manage network data traffic. These devices are responsible for receiving data packets and forwarding them to their intended destination within a network. Switches make decisions based on the destination MAC (Media Access Control) address of the packets, allowing them to efficiently direct traffic and ensure that data reaches the appropriate devices. Unlike software packages or network interface cards, switches are physical devices that provide a crucial function in controlling and managing data flow within a network.

A server is a combination of hardware and software that is specifically designed to provide services to clients. This can include tasks such as hosting websites, managing databases, or providing file storage. Servers are typically installed in computers and allow access to a network through Ethernet or Wireless connections. They act as a central hub that receives data from other components on the network and processes it accordingly to fulfill client requests.

The answer is Network Interface Card

SPAM, in the context of using the Internet, refers to unsolicited email or web page material that is typically in the form of advertisements. It is sent or displayed to users without their consent or request. This type of content is often unwanted and can be considered a nuisance. It is not a computer virus, canned meat, or extra web pages on a chosen topic.

To restrict unauthorized access to a wireless network, it is important to consider all of the mentioned options. Not broadcasting the network name (SSID) makes it harder for potential intruders to discover the network. Only allowing access to specified devices ensures that only authorized devices can connect to the network. Finally, using data encryption, such as WPA2, protects the information transmitted over the network from being intercepted and accessed by unauthorized users. By implementing all of these measures, the security of the wireless network can be significantly enhanced.

A peer-to-peer network is the correct answer because it refers to a network where computers are connected to each other and share their files and printers without the need for a central server. In this type of network, all computers have equal status and can act as both clients and servers, allowing for decentralized sharing of resources.

A NIC (Network Interface Card) is a material or technology used to establish the communications channel in a computer and attaches to the cable or wireless technology used to connect the devices in a network. This card allows the computer to send and receive data over the network, enabling communication between devices.

A smart phone is a convergence of technologies that has resulted in a device also performing the functions of a different device. This means that a smart phone combines various technologies such as computing, communication, and multimedia capabilities, allowing it to not only function as a phone but also perform tasks that were traditionally done by separate devices, such as cameras, music players, and personal digital assistants (PDAs).

The correct answer is "None of the Above" because all the options listed (Cables, Fiber Optics, and Radio Waves) are examples of communication media. Cables are physical wires used to transmit data, fiber optics use light signals to transmit data, and radio waves are used for wireless communication. Therefore, none of the options provided are not examples of communication media.

An intranet is a private network that allows restricted access to company information and supports workers working in groups using the Internet and web technologies. It is different from the capability of a computer to communicate with other computers, as it specifically refers to a network within a company or organization. It is also different from hardware and software that restricts access to data and information on a network, as an intranet is a network itself rather than a security measure. Lastly, an intranet is not necessarily a WAN (Wide Area Network), as it can be a local network within a specific location or office.

When networking computers, sharing resources such as printers, storage devices, and software applications becomes possible. This eliminates the need for each computer to have its own dedicated resources, resulting in cost savings. By sharing resources, businesses can optimize their productivity and efficiency without the need to purchase additional equipment for each individual computer. This also allows for easier management and maintenance of resources, further enhancing efficiency.

A node refers to any device or object that is connected to a network. It can be a computer, a server, a printer, or any other device that is part of the network. Therefore, anything physically connected to a network is called a node.

The answer is protocol

file server, print server and an internet server are examples of servers, some larger networks may have them, but not all

The second option "www.yahoo.com" is a typical web address for the Yahoo website. The third option "http://192.168.0.1" is an IP address, which can also be used as a web address to access a specific device or network. Therefore, none of the above options are NOT examples of web addresses.

A NIC (Network Interface Card) is a hardware component that allows a computer to connect to a network. Both a Wireless Card and an Ethernet Card are common examples of NICs as they enable a computer to connect to a network wirelessly or through an Ethernet cable respectively. However, a Filter, Port, and Firewall are not examples of NICs as they perform different functions in a network setup.

A dial-up modem is a device that converts analogue signals into digital signals and vice versa. This conversion is necessary because computers transmit and receive digital signals, while telephone lines transmit analogue signals. The modem allows the computer to communicate over a telephone line by converting the digital signals from the computer into analogue signals that can be transmitted over the phone line, and then converting the analogue signals received from the phone line back into digital signals that the computer can understand. This enables the computer to access the internet or communicate with other computers using a dial-up connection.
