Networks are comprised of four basic elements: hardware, software, protocols and the connection medium. All data networks are comprised of these elements, and cannot function without them.
What are the 4 types of networking?
- PAN (Personal Area Network)
- LAN (Local Area Network)
- MAN (Metropolitan Area Network)
- WAN (Wide Area Network)
What are the criteria for networking?
What are the three criteria necessary for an effective and efficient network? The most important criteria are performance, reliability and security. Performance of the network depends on number of users, type of transmission medium, the capabilities of the connected h/w and the efficiency of the s/w.
What are the four 4 basic characteristics of reliable network architecture?
Network Architecture
Fault Tolerance. Scalability. Quality of Service (QoS) Security.
What are components of networking?
The hardware components are the server, client, peer, transmission medium, and connecting devices. The software components are operating system and protocols.

What is 4 layer networking model?
The TCP/IP model is a four-layer model that consists of the Application, Transport, Internet, and Network Access layers. The application layer protocol suite includes HTTP, FTP, SMTP, and DNS. Standard protocols associated with the Transport layer include TCP and UDP.
What are the Layer 4 devices?
Layer 4 (The Transport Layer)
are included with each packet and uses this information to hand off the packet to the appropriate higher-layer software. Layer 4 switches make packet forwarding decisions based not only on the MAC address and IP address, but also on the application a packet belongs to.
Which layer 4 protocol is connection oriented?
TCP, or the Transmission Control Protocol, is connection oriented. This means that when a TCP conversation occurs a session is established and that session is used to control and ensure the flow of data between.
What are layer 4 addresses?
Layer 4 Transport Layer
A data segment is a Service Data Unit, which is used for encapsulation on the fourth layer (transport layer). It consists of protocol elements that contain Layer 4 information control. When addressing the data segment assigned a Layer 4 address, so a port.
What is the meaning of 4 layer?
What Does Layer 4 Mean? Layer 4 refers to the fourth layer of the Open Systems Interconnection (OSI) Model, known as the transport layer. It provides the transparent transmission or transfer of data between end systems or hosts and is responsible for end-to-end error recovery, as well as flow control.
What is the most common layer 4 protocol used on the Internet?
The two most common layer four protocols are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). As with many Internet protocols, the File Transfer Protocol (FTP) uses the Transmission Control Protocol (TCP) to provide guaranteed delivery on top of the Internet Protocol (IP).
What are the 4 types of addresses defined at different layers of TCP IP suite?
Four levels of addresses are used in an internet employing the TCP/IP protocols: physical, logical, port, and specific.
What are the 3 types of addresses in a network?
Some link-layer protocols define three types of addresses: unicast, multicast, and broadcast.
What are the four 4 layers of the TCP IP model from top to bottom?
The TCP/IP model comprises four layers: the network access layer, the internet layer, the transport layer, and the application layer (going from bottom to top).
Does TCP IP have 4 or 5 layers?
Check out our Code of Conduct. Answering your question the TCP/IP model has 5 layers: Application, tansport, network and host-to-network.
What OSI layer is DNS?
At a high level, the DNS protocol operates (using OSI model terminology) at the application level, also known as Layer 7. This layer is shared by HTTP, POP3, SMTP, and a host of other protocols used to communicate across an IP network.
What is the most common network protocol?
HTTP – One of the most familiar protocols, hyper text transfer protocol (HTTP) is often referred to as the protocol of the internet. HTTP is an application layer protocol that allows the browser and server to communicate.
Which OSI layer 4 protocol sets up a connection before allowing hosts to communicate?
Layer 4 uses TCP and UDP protocols to create the end-to-end connection between hosts. TCP (Transmission Control Protocol) is the connection-oriented protocol that establishes a robust connection between two end hosts.
What is Layer 4 in OSI model example?
Typical examples of layer 4 are the Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
What is 4 layer architecture?
The four layers of four-tier architecture are presentation layer (PL), data service layer (DSL), business logic layer (BLL), and data access layer (DAL).
What is networking layer 4 and 7?
Layer 4 uses only TCP connection from client to the server while layer 7 uses two TCP connections from client to the server. Layer 7 has application awareness whilst layer 4 only has on network and application ports.
What is a layer in networking?
In networking, layering means to break up the sending of messages into separate components and activities. Each component handles a different part of the communication. This can be referred to as the Transmission Control Protocol/Internet Protocol (TCP/IP) model.
What layer is IP?
Network layer, layer 3. The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks--hence, the name internet.
What is a TCP IP network?
TCP/IP stands for Transmission Control Protocol/Internet Protocol. TCP/IP is a set of standardized rules that allow computers to communicate on a network such as the internet.
