Presentation Layer - ASCII or EBCDEC data syntax. Makes the type of data transparent to the layers around it. Used to translate date to computer specific format such as byte ordering. It may include compression. It prepares the data, either for the network or the application depending on the direction it is going.

What are the types of worms in computer science?
In computer science, worms are a type of malware that replicate themselves to spread to other computers, often without any user intervention. The main types include network worms, which exploit vulnerabilities in network protocols to propagate across connected systems, and email worms, which spread through infected email attachments or links. Additionally, there are file-sharing worms that spread via peer-to-peer networks and mobile worms that target smartphones and other mobile devices. Each type leverages different methods for propagation and can cause varying degrees of damage to systems and networks.

What is inter network?
An internetwork is a collection of individual networks, such as LANs or WANs, connected by routers to enable communication across different networks. It allows devices on different networks to exchange data by forwarding packets between them. The internet is a prime example of a vast internetwork connecting millions of networks worldwide.
What represent and transfer information between computers and network systems?
Data packets represent and transfer information between computers and network systems. These packets contain payloads of data, along with headers that include source and destination addresses, allowing them to navigate through networks efficiently. Protocols like TCP/IP govern how these packets are formatted, transmitted, and received, ensuring reliable communication across various devices and networks.
What is the name of a network layer packet?
A network layer packet is commonly referred to as a "packet" or specifically an "IP packet" when discussing Internet Protocol (IP). At this layer, data is encapsulated into packets for routing across different networks. The network layer is responsible for addressing and forwarding these packets to their destination.
What device acts as a gateway to allow hosts to send traffic to remote IP networks?
A router acts as a gateway that allows hosts to send traffic to remote IP networks. It routes data packets between different networks, determining the best path for the data to reach its destination. By connecting local networks to the internet or other remote networks, routers facilitate communication and data exchange across diverse systems.

What is communication between networks?
Communication between networks, often referred to as inter-network communication, involves the exchange of data and information between different computer networks. This is typically facilitated through protocols such as TCP/IP, which allow devices on separate networks to connect and communicate effectively. Routers play a crucial role in directing data packets across these networks, ensuring they reach their intended destinations. Overall, this interconnectedness enables seamless global communication and data sharing.
Which layer routes packet to destination?
The layer responsible for routing packets to their destination is the Network layer, which is the third layer in the OSI model. It manages the delivery of packets across multiple networks by determining the best path for data to travel from the source to the destination. Protocols such as Internet Protocol (IP) operate at this layer, facilitating logical addressing and routing decisions.
What software program relays mail across computer networks such as the Internet?
Any mail server program. You mean which protocol? That would be SMTP, the Simple Mail Transport Protocol.
What is IP responsible for?
IP, or Internet Protocol, is responsible for addressing and routing packets of data across networks. It ensures that data sent from one device reaches the correct destination by assigning unique IP addresses to devices and managing the transmission of data packets. Additionally, IP facilitates the fragmentation and reassembly of data to accommodate various network sizes and types.
Which layer is responsible for determining the best path a packet should travel across an internetwork?
The layer responsible for determining the best path a packet should travel across an internetwork is the Network layer, which is Layer 3 of the OSI model. This layer uses routing protocols and algorithms to analyze network conditions and select the most efficient route for data packets. Devices such as routers operate at this layer to facilitate the forwarding of packets between different networks.
What is routing and forwarding?
Routing is the process of determining the optimal path for data to travel across a network from the source to the destination. It involves making decisions based on routing protocols and algorithms to find the best route. Forwarding, on the other hand, is the actual movement of packets along the selected path, where network devices, like routers, direct incoming packets to their appropriate outgoing interfaces. Together, routing and forwarding ensure efficient data transmission across complex networks.
