What Is Network Switching?
Switching in IT and computer networking is the transfer of data packets, or blocks of data, through a network switch. Switches transfer data from source ports on devices such as computers to destination ports on devices such as routers.
1. What is a switch?
A switch is a hardware component in network infrastructure that performs the switching process. The switch connects network devices, such as computers and servers, to one another.
A switch enables multiple devices to share a network while preventing each device's traffic from interfering with other devices' traffic. The switch acts as a traffic cop at a busy intersection. When a data packet arrives at one of its ports, the switch determines which direction the packet is headed. It then forwards the packet through the correct port for its destination.

2. What is a Router?
A router receives and sends data on computer networks. Routers are sometimes confused with network hubs, modems, or network switches. However, routers can combine the functions of these components, and connect with these devices, to improve Internet access or help create business networks.

3. What Is a Firewall?
A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.
Firewalls have been a first line of defense in network security for over 25 years. They establish a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks, such as the Internet.
A firewall can be hardware, software, software-as-a service (SaaS), public cloud, or private cloud (virtual).

4. What is a wireless access point?
A wireless access point (WAP) is a networking device that allows wireless-capable devices to connect to a wired network. It is simpler and easier to install WAPs to connect all the computers or devices in your network than to use wires and cables.Using a WAP lets you create a wireless network within your existing wired network, so you can accommodate wireless devices.
You can also use a WAP or mesh extenders to extend the signal range and strength of your wireless network to provide complete wireless coverage and get rid of "dead spots," especially in larger office spaces or buildings. Additionally, you can configure the settings of your WAPs using a single device.

5. What is an IP phone and how does it work?
IP phones consist of a hard or soft IP phone, a VoIP branch exchange and a VoIP service provider or Local Area Network. IP phones work by compressing voice signals from the phone and converting them into digital signals. These digital signals then travel through the VoIP phone system and into a private or local area network. On the receiving end, files are decompressed and changed back into normal-sounding audio for the listener.
IP phones will work in any location where they can be accessed by the internet. For global companies, this means employees can connect to their phones even while traveling abroad.
Same look and feel – IP phones are similar to their analog counterparts, just with potentially more features. As a result, users won’t need extensive training to get accustomed to IP phones.
Cost-savings – Since IP phones use the internet to make and receive calls, you can save money by getting rid of your landline and instead utilize your existing private internet networks.
Unlimited simultaneous calls – Cloud phone systems allow for multiple calls to take place at once, meaning your services will no longer be limited by the number of rollover lines, physical phones, or people available to answer the calls.
