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 is the process of breaking down information sent or transmitted across the Internet into small parts called packets?
Packetization is the process of breaking down information sent or transmitted across the Internet into small parts called packets. Packetization is used in many different fields.

Which three pieces of information must be specified on a computer to allow that computer to send and receive information across networks? (Choose three.) IP address subnet mask closest server default gateway operating system network card manufacturer
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.

Router
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 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.
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 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.
List the main responsibility of the Internet Protocol?
To transfer data packets across the Internet
What is the difference between a software virus and a software worm?
A software virus attaches itself to a program or file and requires user action to spread, while a software worm can self-replicate and spread without user intervention. Viruses need a host file to infect, while worms can move across networks independently.
What is the difference between a wireless port and a router?
I assume you mean wireless access point? A wireless access point allows you to connect wirelessly to a wired network. A router routes packets across different networks/subnets. Both are completely different devices but can be bundled together.
What osi layer handles ip address?
The OSI layer that handles IP addresses is the Network layer, which is the third layer of the OSI model. This layer is responsible for routing packets across different networks and managing logical addressing, such as IP addresses, to ensure that data can be sent and received between devices on different networks. Additionally, it facilitates the selection of optimal paths for data transmission.
Which two functions are primary functions of a router?
The primary functions of a router are to connect multiple networks and to direct data packets between them. Routers determine the best path for data to travel across these networks using routing tables and protocols. Additionally, they can provide network address translation (NAT) to allow multiple devices on a local network to share a single public IP address.
