Computer networking basics for beginners
In this article we will go over the concepts of computer networking basics for beginners, which may be of interest if you are looking to setup your own home office or home networking situation.
There is an obvious need for an organisation to have a network setup for computers to aid in data sharing, retrieval of data and to optimise the use of computer resources
There are a few different types of computer networks and these include:
- Local Area Network (LAN)
- Metropolitan Area Network (MAN)
- Wide Area Network (WAN)
In order to get started you need three main functions so your computers know how to interact with each other, these include:
1. To have a unique address
2. To be connected by cable or wireless networking which is also known as connection media
3. To have a common network language used which is known as a protocol
For this article based on computer networking basics for beginners we will mainly focus on a LAN.
This is a network that deals with a small area of computer networks, which is usually for a small office or computer cafe.
Networking basics concepts for beginners
Most modern networks these days will use Wi-Fi the main connection tool to transfer data, though in an office situation this may be mixed with wired and wireless.
In most situations computers will be connected to an Ethernet network, and each device on the network will need to be connected to a hub or a switch.
For a wireless network each decide must connect to a wire access point.
To enable a computer to communicate on the network it will need it’s own unique address. This is also known as a MAC (media access control address) and is built into the network.
A MAC address us shows as 6 hexadecimal numbers separated by columns.
How to learn computer networking basics
If you want to get started on concepts of computer networking basics for beginners then you should start reading up on some books written on this topic. We will go over a few of the basics you should learn about to get started on computer networking basics.
There are many places where you can find free tutorials such as YouTube and udemy.
If if you know nothing about networking you should look for a course that covers MTA servers, Networking, and VPN’s.
A well covered course on how to learn computer networking basics should cover the following:
- Why do we need networks in our home or work environment
- Basic commands such as trace-route, ping and ipconfig
- How to troubleshoot a home network
- Wireless issues and configuration guides
- How to start a career in IT
A course that covers computer networking basics for beginners should be the perfect stepping stone for a pathway to courses like a CCNA or MTA course.
Networking protocols you should know about
All home networks for the office and corporate environment use the TCP / IP networking protocol.
This protocol also has IP address which are assigned b using a service called DHCP (Dynamic host configuration protocol)
- Bridges – Bridges are used to join network segments together for example on a LAN.
- Router – This is used to connect different networks together, it is responsible for the determination of sent data.
- Wireless router – This is an item you may have in your home and it helps to connect devices without a wire.
- Ethernet – Network cables are referred to as Ethernet cables and they are used to connect a computer to all other networking devices.
- IP address – This is a 32 bit address given to computers, switches and routers so they can be easily located by other devices on the network. We currently have IPv4 and IPv6.
- Hubs & Switches – Hubs operate at the physical level and are a primate device for connection computers together.
- Data frames and packets – Data is transferred between computers as frames or packets. When you have Ethernet frames and IP packets the data frame contains the frame management information.
- IP address and MAC address – To send a data packed the sender needs to know the IP address of the destination device. The IP address with be used to get the data packed to the final network segment.
- Subset mask – This helps to determine the class of an IP address as it is assigned to other switchers and routers.
- DHCP – Dynamic host configuration protocol is a server of automatically assigned IP address to host devices such as computers. This process is carried out by a router.
- Wi-Fi – This is a method of connecting computers together to a network without the use of cables.
Networking basics interview questions and answers
If you have just finished a degree in networking or ever a smaller course at a local college, you may want to start working in the IT field as a network assistant, or network administrator.
When you go for an interview you will need to know some information about computer networking basics for beginners so you can answer all of the questions accurately and in a succinct manner.
Many interviewers in this field will only want to take on intelligent and well educated trainees to onboard into into the company.
Each company will have a different process for taking on new employees and will have set protocols and information management tools that keep the company running.
Here are some of the top 8 networking basics interview questions and answers:
- What is a Point-to-Point network
- What are routers
- What is a LAN
- What is network topology
- What does a backbone network mean
- What do you mean by node
- What is a link
- What is the different between a router, a hub and a switch
These are some networking basics interview questions and answers, as networking has such a wide spectrum of platforms there would be several other questions that you may be asked during the interview.
If you have a clear understanding of the questions here then you can be slightly more confident in your next networking job interview. Be sure to read out post on Monitors for work if you liked this post.
