1. What Is a Network?
A network is a group of connected devices that share information or resources. These devices communicate with each other over the network, which can be wired or wireless, and can vary in size from a small home network to a large global one, like the Internet. Of all networking basic interview questions, this is one you should be able to answer automatically! Find Remote Networking Jobs
2. How Are Network Types Classified? Explain the Difference.
Network types are characterized based on their size, geographical dispersion, and how devices connect. The fundamental distinction between these network types is their geographical range and the devices they link. This is another one of the most basic networking questions, so make you know these!
3. What Is a Data Packet?
A data packet is a unit of data that is transferred over a network. It includes data and control information, including the source, destination addresses, and error-checking information. When you send an email, your computer breaks it down into data packets to send it over the network. On the receiving end, the packets are reassembled into the original message. Data packets enable us to send data efficiently over long distances.
16. What Is the Difference Between Ipconfig and Ifconfig?
They are command-line tools used to view and configure network settings, including changes to the DHCP and DNS settings.
17. What Is the Purpose of the Ping Command?
Ping is a diagnostic tool to test network connectivity that sends an ICMP echo request to a target device and waits for a response. The purpose of pinging is to verify that a network device is responsive and to measure the time it takes for data packets to travel to/from the source. Pinging can help identify network issues (like packet loss) and is often used in troubleshooting.
18. What Is the OSI Reference Model? Describe the Layers.
The Open Systems Interconnection (OSI) reference model is a seven-layer architecture that specifies how data is conveyed across a network. The OSI model provides a standardized approach to network communication that enables devices to coexist. The layers are as follows:
28. What Are CIDR Blocks?
Classless Inter-Domain Routing (CIDR) is a method of allocating IP addresses and defining network boundaries. CIDR blocks are defined via the combination of an IP address and a subnet mask, enabling the specification of which addresses are included in the block. For example, the CIDR block 192.168.0.0/24 would include all IP addresses from 192.168.0.0 to 192.168.0.255, with the subnet mask being 255.255.255.0. CIDR blocks are commonly used by ISPs to allocate IP addresses to customers and by...
29. What Is the Difference Between TCP and UDP Protocols?
TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both protocols for sending send data over the Internet, with the primary difference being the way they transmit data. This is one of the most popular computer networks interview questions, so be sure to know this!
30. What Is the DHCP Protocol?
DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses to networked devices. This happens when a device connects to a network, as it sends an IP address request, which the DHCP server responds to.
39. What Is the Main Function of a Router in a Network?
1. To provide network security 2. To connect multiple networks 3. To manage data storage 4. To control network access
40. What Protocol Is Used for File Transfers Over a Network?
1. FTP 2. HTTP 3. SMTP 4. TCP
41. What Is the Most Commonly Used IP Address Range for Private Networks?
1. 192.0.0.0 - 192.255.255.255 2. 10.0.0.0 - 10.255.255.255 3. 127.0.0.0 - 127.0.0.1 4. 169.254.0.0 - 169.254.255.255
