TCP/IP is a Network Protocol, but what does it really do???

Question

I know that TCP/IP is very advantageous but does it also have disadvantages in it???

Answer 1

The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite, often simply referred to as TCP/IP. Using TCP, applications on networked hosts can create connections to one another, over which they can exchange streams of data using Stream Sockets. Unlike the UDP protocol this protocol guarantees reliable and in-order delivery of data from sender to receiver. TCP also distinguishes data for multiple connections by concurrent applications (e.g., Web server and e-mail server) running on the same host.



TCP supports many of the Internet's most popular application protocols and resulting applications, including the World Wide Web, e-mail, File Transfer Protocol and Secure Shell.



In the Internet protocol suite, TCP is the intermediate layer between the Internet Protocol (IP) below it, and an application above it. Applications often need reliable pipe-like connections to each other, whereas the Internet Protocol does not provide such streams, but rather only best effort delivery (i.e., unreliable packets). TCP does the task of the transport layer in the simplified OSI model of computer networks. The other main transport-level Internet protocol is UDP.



Applications send streams of octets (8-bit bytes) to TCP for delivery through the network, and TCP divides the byte stream into appropriately sized segments (usually delineated by the maximum transmission unit (MTU) size of the data link layer of the network to which the computer is attached). TCP then passes the resulting packets to the Internet Protocol, for delivery through a network to the TCP module of the entity at the other end. TCP checks to make sure that no packets are lost by giving each packet a sequence number, which is also used to make sure that the data is delivered to the entity at the other end in the correct order. The TCP module at the far end sends back an acknowledgement for packets which have been successfully received; a timer at the sending TCP will cause a timeout if an acknowledgement is not received within a reasonable round-trip time (or RTT), and the (presumably) lost data will then be re-transmitted. The TCP checks that no bytes are corrupted by using a checksum; one is computed at the sender for each block of data before it is sent, and checked at the receiver.

Answer 2

TCP/IP is a network protocol, that basically takes some information (like a web page) breaks it down into smaller components and addresses each individual component (or packet) to the computer it is going to. Advantage: Simple, connection tracking, can recover lost packets. Disadvantage: very prone to attacks

Answer 3

The Internet communication protocol defines the rules for computer communication over the Internet.



Basically its wat connects the computer browser to access internet servers and what sends the html code back to your comptuer.





Without it there would be no internet, but some disadvantages are:



Network Hardware, Software and Setup Costs



Hardware and Software Management and Administration Costs



Undesirable Sharing:One significant “sharing problem” in this regard has to do with viruses, which are easily spread over networks and the Internet. Mitigating these effects costs more time, money and administrative effort.



Illegal or Undesirable Behavior: Typical problems include abuse of company resources, distractions that reduce productivity, downloading of illegal or illicit materials, and even software piracy.



Data Security Concerns:In contrast, a poorly-secured network puts critical data at risk, exposing it to the potential problems associated with hackers, unauthorized access and even sabotage.

Configure your laptop to receive all the settings dynamically. The IP address (& netmask, gateway) and the DNS servers. Login to your router's configuration page and enable DHCP. If necessary, also configure the router at your parents place. Next time your laptop latches onto the wireless router, it will get an IP from the router. The router will also send it's IP as the gateway IP and it's IP as the DNS server. When your computer requests information from the web, it will send the request to the router which will do the needful and connect your PC to the web-server. I am hoping that you have some idea of TCP/IP concepts. Else you will either have to work with the router config. wizard or do a bit of quick reading.

Answer 5

Without TCP/IP the Internet would NOT Exist.
