Show the contents of a priority queue after the following operations. Assume the queue starts out empty. For the enqueue operation, the first parameter is the element and the second parameter is its priority so that (45, 5) means element 45 has a priority of 5. Assume that the smaller the number the higher the priority. enqueue (45, 5); enqueue (12, 8); enqueue (28, 2); dequeue(); dequeue(); enqueue (69, 0); enqueue (27, 6); enqueue (99, 9); dequeue(); enqueue (24, 4); enqueue (85, 2); enqueue (16, 3); dequeue();

Port number 20, Protocol TCP, Application FTP (data). File transfer protocol. Used to transfer files between computers. Considered insecure
Port number 21, Protocol TCP, Application FTP (control). uses TCP port 21 to establish a connection between the client and FTP server. In order to start a data transfer session
Port number 22, Protocol TCP, Application, SSH. Secure Shell or Secure Socket Shell provides a strong authentication and encrypted data transport between a client and remote computer. Like Telnet, it provides a command line on the remote computer.
Port number 23, Protocol TCP, Application Telnet. Telnet is an insecure remote access protocol that provides a command line on a remote computer. SSH is preferred for security reasons.
Port number 25, Protocol TCP, Application SMTP. Simple Mail Transfer Protocol is used to send email from clients to an email server. It may also be used to relay email messages from source to destination email servers.
Port number 53, Protocol TCP/UDP, Application DNS, protocol finds the IP address associated with a registered Internet domain for Web, Email, and other Internet services. It uses UDP for requests and information transfer between DNS servers. TCP will be used for DNS responses if required
Port number 67, Protocol UDP, Application DHCP (server). Dynamic Host Configuration Protocol automatically provides IP addresses to network hosts and provides a way to manage those addresses.
Port number 68, Protocol UDP, Application DHCP (client). Dynamic Host Configuration Protocol automatically provides IP addresses to network hosts and provides a way to manage those addresses.
Port number 69, Protocol UDP, Application TFTP. Trivial File Transfer Protocol utilizes less overhead than FTP.
Port number 80, Protocol TCP, Application HTTP. Hypertext Transfer Protocol (HTTP) provides a set of rules for exchanging text, graphic images, sound, video, and other multimedia files on the World Wide Web.
Port number 110, Protocol TCP, Application POP3. Post Office Protocol 3 is used by email clients to retrieve messages from an email server.
Portnumber 137-139, Protocol TCP, UDP, Application NetBIOS/NetBT. NetBIOS over TCP/IP provides a system through which older computer applications can communicate over large TCP/IP networks. Different NetBT functions use different protocols and ports in this range.
Port number 143, Protocol TCP, Application IMAP. Internet Message Access Protocol is used to retrieve email messages from a server. It is more advanced than POP3 and offers a number of advantages.
Port number 161/162, Protocol UDP, Application SNMP. Simple Network Management Protocol enables network administrators to monitor network operations from centralized monitoring stations.
Port number 389, Protocol TCP,UDP, Application LDAP. Lightweight Directory Access Protocol is used to maintain user identity directory information that can be shared across networks and systems. It can be used to manage information about users and network resources. It can be used to authenticate users on multiple computers.
Port number 427, Protocol TCP,UDP, Application SLP. Service Location Protocol allows computers and other devices to locate services on a LAN without previous configuration. Usually uses UDP, but can use TCP.
Port number 443, Protocol TCP, Application HTTPS. Secure HTTP
Port number 445, Protocol TCP, Application SMB/CIFS. Server Message Block or Common Internet File System allow for sharing of files, printers, and other resources between nodes on a network.
Port number 548, Protocol TCP, Application AFP. Apple Filing Protocol is a proprietary protocol developed by Apple to enable file services for macOS and classic Mac OS.
Port number 3389, Protocol TCP,UDP, Application RDP. Remote desktop protocol was developed by Microsoft to provide remote access to the graphical desktop of a remote machine. It is useful for tech support situations, however it should be used with caution because it provides a remote user with complete control of the destination computer

The Institute of Electrical and Electronic Engineers' (IEEE) standards for Wi-Fi as specified in the 802.11 collective group of standards that specify the radio frequencies, speeds, and other capabilities for WLANs. Various implementations of the IEEE 802.11 standards have been developed over the years

The 802.11a, 802.11b, and 802.11g standards should be considered legacy. New WLANs should implement 802.11ac devices. Existing WLAN implementations should upgrade to 802.11ac when purchasing new devices.

IEEE Standard: 802.11a, Maximum Speed: 54 Mb/s, Maximum Indoor Range: 115 ft (35 m), Frequency: 5 Ghz, Backwards Compatible: None.
IEEE Standard: 802.11b, Maximum Speed: 11 Mb/s, Maximum Indoor Range: 115 ft (35 m), Frequency: 2.4 Ghz, Backwards Compatible: None.
IEEE Standard: 802.11g, Maximum Speed: 54 Mb/s, Maximum Indoor Range: 125 ft (38 m), Frequency: 2.4 Ghz, Backwards Compatible: 802.11b.
IEEE Standard: 802.11n, Maximum Speed: 600 Mb/s, Maximum Indoor Range: 230 ft (70 m), Frequency: 2.4 Ghz and 5 Ghz, Backwards Compatible: 802.11a/b/g.
IEEE Standard: 802.11ac, Maximum Speed: 1.3 Gb/s (1300 Mb/s), Maximum Indoor Range: 115 ft (35 m), Frequency: 5 Ghz, Backwards Compatible: 802.11a/n.

2.5G description, .5G supports web browsing, short audio and video clips, games, and downloads of applications and ring tones.Speed: 9.6 Kb/s to 237 Kb/s.
3G description, 3G supports full-motion video, streaming music, 3D gaming, and faster web browsing.Speed: 144 Kb/s to 2 Mb/s.
3.5G description, 3.5G supports high-quality streaming video, high-quality video conferencing, and Voice over IP (VoIP).VoIP is a technology that applies internet addressing to voice data.Speed: 400 Kb/s to 16 Mb/s.
3.5G description, 3.5G supports high-quality streaming video, high-quality video conferencing, and Voice over IP (VoIP).VoIP is a technology that applies internet addressing to voice data.Speed: 400 Kb/s to 16 Mb/s.
4G description, 4G supports IP-based voice, gaming services, high-quality streamed multimedia, and Internet Protocol version 6 (IPv6). IPv6 is the newest version of internet addressing.No cell phone carriers could meet the 4G speed standards when first announced in 2008. Speed: 5.8 Mb/s to 672 Mb/s.

Which required network device is generally integrated in computer and laptops?

Also known as an Ethernet adapter, a network interface card (NIC) is a chip or circuit board that generally comes preinstalled on a computer or device.

Which internal hardware device is required for a computer to connect to a network?

Network interface card (NIC). A NIC is a circuit board or chip that enables the computer to connect to a network; also known as a network adapter or local area network adapter, it typically supports connection to an Ethernet network.

Personal Area Network (PAN): It is an interconnection of personal technology devices to communicate over a short distance, which is less than 33 feet or 10 meters or within the range of an individual person, typically using some form of wireless technologies.

Which of the following is the most common network connectivity method for laptops and other mobile devices?

Wi-Fi. Wi-Fi is the most popular type of network connection. Unlike wired connection types, such as Ethernet, it does not require a physical cable to be connected. Instead, data is transmitted through wireless signals.
