Computer Communication Protocol and Types of Internet Connection

• TCP/IP is the communication protocol for communication between computers on the network.

• TCP/IP defines how electronic devices should be connected to the Internet, and how data should be transmitted between them.

• TCP/IP has several protocols for handling data communication: TCP, UDP, IP, ICMP, DHCP, etc.

• TCP is for communication between applications, while UDP is simpler and less reliable.

• IP is for communication between computers and is a "connection-less" communication protocol.

• IP reduces the need for network lines and messages are broken up into small independent "packets" and sent between computers via the Internet.

• TCP/IP addressing requires each computer to have a unique IP address, which is always written as four numbers separated by a period.

• TCP/IP uses 32 bits addressing, which means it uses four computer bytes.

• TCP/IP is a large collection of different communication protocols based upon the two original protocols TCP and IP, including HTTP, HTTPS, FTP, SMTP, etc.

• Types of internet connection include cable modem, DSL, fiber optics, satellite networking, ISDN, cellular networks, LTE and HSPA+, and WiMAX.

• Cable modem and DSL offer high-speed networking, while fiber optics converges services including video, voice, and data.

• Cellular networks, LTE and HSPA+, and WiMAX offer wireless high-speed internet access, but satellite networking has a high cost relative to terrestrial networking and high latency.Networking Concepts Self-Check Quiz Summary

• The quiz covers basic concepts of computer networking, including LAN, WAN, MAN, PAN, SAN, Ethernet, internet, VPN, client/server, and peer-to-peer networks.

• A computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of users.

• A LAN is usually a small network constrained to a small geographic area, while a WAN is a computer network that covers a broad area.

• A MAN is a hybrid between a LAN and a WAN, connecting two or more LANs in the same geographic area, while a PAN is a computer network used for communication among computer devices in proximity to an individual's body.

• A SAN is a dedicated storage network that provides access to consolidated, block-level storage.

• The internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide.

• A VPN is a private network that is constructed within a public network infrastructure such as the global Internet.

• Client/server networking refers to the concept of sharing the work involved in processing data between the client computer and server computer.

• In a peer-to-peer network, there are no dedicated servers or hierarchy among the computers.

• The quiz consists of ten multiple-choice questions, and the answer key is provided.

• The quiz emphasizes the importance of understanding basic networking concepts, which are essential for building and maintaining computer networks.

• The quiz encourages learners to answer according to their mind and heart’s content, without fighting for the wrong answer, and not to play with the questionnaire.

Overview of Computer Communication Protocol and Types of Internet Connection

• TCP/IP is the communication protocol used for communication between computers on the network.
• TCP/IP defines how electronic devices should be connected to the Internet, and how data should be transmitted between them.
• TCP/IP has several protocols for handling data communication, such as TCP, UDP, IP, ICMP, DHCP, among others.
• TCP is used for communication between applications, while UDP is simpler and less reliable.
• IP is a "connection-less" communication protocol that reduces the need for network lines.
• TCP/IP uses four numbers to address a computer, written as four numbers separated by a period, and contains 32 bits or 4 bytes.
• DNS servers are responsible for translating domain names into TCP/IP addresses.
• TCP/IP is a large collection of different communication protocols based upon the two original protocols TCP and IP.
• Cable modem, DSL, SDSL, VSDSL, dial-up, fiber optics, satellite networking, ISDN, cellular networks, LTE/HSPA+, and WiMAX are different types of internet connection.
• Cable modem offers high-speed networking with the speed of 4 Mbits/s through 100 Mbits/s with multiple services.
• DSL uses telephone lines and has a 10,000-foot limitation from the central office, while fiber optics has high-speed networking and converged services.
• Cellular networks have separate land into "cell" with certain frequencies, while WiMAX offers wireless high-speed internet access with a 30 miles signal radius.
