What is a network in a computer?

computer network, two or more computers connected together to communicate data electronically. Two basic network types are Local Area Networks (LANs) and Wide Area Networks (WANs).


What is the first computer network?

The ARPAnet, which was turned on in late October 1969, is the first large-scale general-purpose computer network connecting different types of computers.


ARPANET, a Department of Defense project, was the network where the Internet protocol suite, TCP/IP, was developed and first used. NSFNET followed ARPANET and was designed as a network of research centers and supercomputers communicating over a TCP/IP network, just like ARPANET before it.

What is NS Full Form?

How is LAN different from WAN?

LAN has a higher data transfer rate while WAN has a lower data transfer rate. LAN is a computer network that covers a small geographical area such as a house, office or a group of buildings while WAN is a computer network that covers a larger area. The speed of LAN is high while the speed of WAN is slower than that of LAN.5 days ago.

Where is RAM located?

RAM is physically small and stored in microchips. RAM is usually stored outside the CPU in separate chips. RAM memory modules are installed in slots on the computer’s motherboard.

What is the full form of the Internet?

INTERNET stands for Interconnected Network, a network system that connects millions of web servers. The INTERNET has connected the world through millions of invisible online servers, just like a spider makes its web.

Who invented the internet?

Computer scientists Vinton Cerf and Bob Kahn are credited with inventing the Internet communication protocols we use today and the system called the Internet.

Why is ARPANET important?

ARPANET was created to make it easier for people to access computers, improve computing equipment, and have a more effective method of communication for the military.

What is the purpose of ARPANET?

The Advanced Research Projects Agency (ARPA), a division of the United States Department of Defense, funded the development of the Advanced Research Projects Agency Network (ARPANET) in the late 1960s. Its original purpose was to connect computers at Pentagon-funded research institutions via telephone lines.

How does ARPANET work?

Developed by the US Advanced Research Projects Agency, a Department of Defense agency, ARPANET uses packet switch technology to send and receive data with built-in error correction and packet assembly. ARPANET was the first design of what is known today as the Internet.

What is the full form of PS?

What is a LAN diagram?

Local Area Network diagrams visualize LAN communication schemes and network layout in homes, offices, and buildings. They are used by IT professionals to visually document the physical structure and arrangement of the LAN.

What is a TCP IP model?

The TCP/IP reference model is a four-layer set of communication protocols. TCP stands for Transmission Control Protocol and IP stands for Internet Protocol. The four layers in the TCP/IP protocol suite are − Host-to-network layer −This is the lowest layer that deals with the physical transfer of data.

Where is San used?

SANs are primarily used to access data storage devices, such as server disk arrays and tape libraries, so that the devices appear to the operating system as directly attached storage. A SAN is typically a special network of storage devices that cannot be accessed over the local area network (LAN).

How many networks are there?

Today, the Internet consists of more than 40,000 different networks. These networks still communicate with each other using the TCP/IP standards that Cerf and Kahn developed in the 1970s.

What are the 2 components of a computer?

Every computer consists of two basic components: hardware and software. hardware includes the physical features, any part you can see or touch, for example: monitor, case, keyboard, mouse, and printer. The part that activates the physical components and all software.

Is Wi-Fi a network?

A Wi-Fi network is simply an Internet connection shared through a wireless router with multiple devices in a home or business. The router is connected directly to your internet modem and acts as a hub to broadcast the internet signal to all your Wi-Fi devices.

What is network response?

A network consists of two or more computers connected to each other to share resources (such as printers and CDs), exchange files, or facilitate electronic communication. The computers in a network can be connected to each other via cables, telephone lines, radio waves, satellites or infrared light beams. Wide Area Network (WAN).


I have been blogging since August 2011. I have had over 10,000 visitors to my blog! My goal is to help people, and I have the knowledge and the passion to do this. I love to travel, dance, and play volleyball. I also enjoy hanging out with my friends and family. I started writing my blogs when I lived in California. I would wake up in the middle of the night and write something while listening to music and looking at the ocean. When I moved to Texas, I found a new place to write. I would sit in my backyard while everyone else was at work, and I could write all day.
