In this talk, As you can see on the screen, We can break this area down into the following fields so in my
part
I would like to concentrate on. networks
1. types of networks
2. Benefits of Networks
3. How Networks Are Structured:
SO
Network – or communications network, is a system of interconnected computers, telephones, or other
communications devices that can communicate with one another and share applications and data.
Explanation:
So essentially, network consist of two or more computers to share resources, exchange files or allow
electronic communications. In short it is a communication between two or more computer devices
means when two or more devices are connected to each other for the purpose of communication is
called network.
So, quick history lang po
1950s -1960s:
Terminal-Oriented Computer Networks had begun which were very
expensive. Therefore, time-sharing techniques were developed to allow them
to be shared by many users.
1960s-1970s:
The cost of the computer dropped, and new applications emerged. It becomes
essential to enable mainframe computers to interconnect and communicate
with each other.
1960s APRANET was the first real attempt of developing a network to
interconnect computers over a wide geographic area
1980:
The beginning of Local Area Networks (LANs)
Affordable computers become available.
Varieties of LAN topologies emerged like bus, ring, start, etc.
Dati po bago magkaroon ng computer network po ,
Before we had computer networks po, people use “sneakernet” para po magshare data between
computers po.
So, ano ng aba yung sneakernet?
Sneakernet is a slang term po ito that refers to the transfer of data and electronic files between
computers through removable media (halimbawa po nito ay yung hard drives, flash drives and
optical disks), which are physically transported between computers and on foot. yung method
po na ito is used in lieu of a computer network file transfer.
Yung term po na sneakernet (meant to sound like Ethernet) refers to sneakers worn by the
person carrying files between computers.
-person 1 saved their documents to a floppy disk
then they walked over to person’s desk (wearing sneakers, of course) and handed over the disk to
person 2
-person 2 loaded the disk into their computer to read and edit the document
Since the days of “sneakernet”, networks have become standard. They enable us to:
