Identify the port that can be used to connect up to 127 peripheral devices using a hub.
正確答案:
Explanation:
A single USB port can be extended to more ports using a hub. Universal Serial Bus (USB) is a high speed bus standard developed by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom. It provides the Plug and Play capability of Windows to external hardware devices. USB supports hot plugging, which means that a USB device can be installed or removed while the computer is running.
A single USB port can be used to connect up to 127 peripheral devices, such as CD-ROM drives, tape drives, keyboards, scanners etc. USB 1.1 has a maximum data transfer rate of 12 Mbps, whereas USB
2.0 has a maximum data transfer rate of 480 Mbps. USB 2.0 is fully backward compatible with USB
1.1.
TCP/IP suite contains a number of protocols that perform various tasks to support the transmission of data across a network. TCP/IP suite is the basic communication language or protocol of the Internet.

Explanation:
Domain Name System (DNS) is a hierarchical naming system used for locating domain names on private TCP/IP networks and the Internet. It provides a service for mapping DNS domain names to IP addresses and vice vers
A. DNS enables users to use friendly names to locate computers and other resources on an IP network. TCP/IP uses IP addresses to locate and connect to hosts, but for users, it is easier to use names instead of IP address to locate or connect to a site. For example, users will be more comfortable in using the host name www.Company.com rather than using its IP address
66.111.64.227. Dynamic Host Configuration Protocol (DHCP) is a TCP/IP standard used to dynamically assign IP addresses to computers, so that they can communicate with other network services. It reduces the complexity of managing network client IP address configuration. A DHCP server configures DHCP-enabled client computers on the network and runs on servers only. It also provides integration with the Active Directory directory service. Note: If the DHCP server is offline, a user cannot obtain necessary addresses from the server. Hence, without valid TCP/IP addresses from the DHCP server, the user will not be able to communicate with anyone on the network or access network resources. File Transfer Protocol (FTP) is a primary protocol of the TCP/IP protocol suite, which is used to transfer text and binary files between a host computer and a server computer over the Internet. Hypertext Transfer Protocol (HTTP) is a client/server TCP/IP protocol used on the World Wide Web (WWW) to display Hypertext Markup Language (HTML) pages. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when a client application or browser sends a request to the server using HTTP commands, the server responds with a message containing the protocol version, success or failure code, server information, and body content, depending on the request.
HTTP uses TCP port 80 as the default port. The Internet Protocol (IP) is a protocol used for communicating data across a packet-switched inter-network using the Internet Protocol Suite, also referred to as TCP/IP.IP is the primary protocol in the Internet Layer of the Internet Protocol Suite and has the task of delivering distinguished protocol datagrams (packets) from the source host to the destination host solely based on their addresses. For this purpose, the Internet Protocol defines addressing methods and structures for datagram encapsulation. The first major version of addressing structure, now referred to as Internet Protocol Version 4 (IPv4), is still the dominant protocol of the Internet, although the successor, Internet Protocol Version 6 (IPv6), is being deployed actively worldwide. Transmission Control Protocol (TCP) is a reliable, connection-oriented protocol operating at the transport layer of the OSI model. It provides a reliable packet delivery service encapsulated within the Internet Protocol (IP). TCP guarantees the delivery of packets, ensures proper sequencing of data, and provides a checksum feature that validates both the packet header and its data for accuracy. If the network corrupts or loses a TCP packet during transmission, TCP is responsible for retransmitting the faulty packet. It can transmit large amounts of dat
A. Application layer protocols,
such as HTTP and FTP, utilize the services of TCP to transfer files between clients and servers. User Datagram Protocol (UDP) is one of the core members of the Internet Protocol Suite, the set of network protocols used for the Internet. With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network without requiring prior communications to set up special transmission channels or data paths. UDP is sometimes called the Universal Datagram Protocol.
