Distance limit of UTP cable is 100 meter. Which cable is required to build a 100BaseT network? To build a 100BaseT network, UTP (CAT-5) Cable is required. How much distance does SMF (single mode fiber) cable support? A SMF cable supports a maximum of 2 km distance. Why fiber cable does not get affected from the crosstalk? Fiber cable does not affect from the crosstalk because it uses glass for data transmission. Glass is immune to crosstalk. The crosstalk generates in copper wire which is not used fiber cable. Which connector is used to connect a Thinnet cable with NIC? The BNC (British naval connector) connector is used to connect the Thinnet cable with NIC. Which connector is used to connect a Thicknet cable with NIC? The AUI (Adapter unit interface) connector is used to connect the Thicknet cable with NIC. How is a straight-through UTP cable made? In Straight-through UTP cable, all pins are matched on both sides. Pin-1 connects with Pin-1; Pin2 connects Pin2, this way each pin connects with the same number of pin on other side.

FTP (File Transfer Protocol) uses TCP protocol for data transmission. It not only uses an authentication process before transmission but also uses several mechanisms to ensure the data integrity throughout the transmission. TFTP is built only to use in private network between known devices. It should be never used in public network. FTP is built for both public and private network. It can be used in both networks without any hassle. What is the 10BaseFL architecture? The 10BaseFL is the extended version of 10BaseT architecture. It uses fiber optical cable instead of UTP cable. Usually this architecture is used to build the backbone network. What are the similarities and differences between 100BaseTX and 100BaseFX? Similarities: - Both architectures use Baseband technology for data transmission and provide a maximum speed of 100Mbps. Differences: - 100BaseTx uses UTP (CAT-5) cable while 100BaseFX uses fiber optical cable. What are the differences between the STP cable and the UTP cable?

A password is a secret word that is used to prove the identity of a user in authentication process. A resource secured by authentication process can be accessed only by providing the correct password. What is the UAC? It is a security feature in Windows system that prevents unauthorized applications from running without user permission. At which port does HTTP operate? HTTP operates at port 80. At which port does HTTPS operate? The HTTPS operates at port 443. What does DHCP stand for? DHCP stands for Dynamic Host Configuration Protocol. Every node in an IP network needs IP address to communicate with others. If the number of nodes is high, then assigning and managing IP addresses becomes very difficult. DHCP solves this issue.

Based on geographical location what are the two most common network types? LAN (Local Area Network) and WAN (Wide Area Network) What is the difference between point to point and point to multipoint topology? In point to point topology once system connects with another system directly. In point to multipoint topology all systems connect through a centralized device. Where is Mesh topology used? Mesh topology is used in WAN network to build the alternative paths between networks. What is the main advantage of Mesh topology? It creates redundant links between nodes which keep alive the network till the last active link. Why a system cannot monopolize the Token Ring LAN? Each system gets the token only for a specific period of time. Once that time period is expired, it must have to release the token. What are the differences between TFTP and FTP? TFTP (Trivial File Transfer Protocol) uses UDP protocol for data transmission. It neither uses an authentication process before transmission nor uses any mechanism to ensure the data integrity throughout the transmission.

For example, Hub and Switch both are used to connect the multiple computers together. But Hub is considered as a physical layer device while Switch is considered as Data Link layer device. Reason being, a Switch handles data in frame format while a Hub handles data in signal format. In which layers of OSI model, does Ethernet work? Ethernet works in first two layers of OSI model; Physical layer and Data Link layer. What does the term packet define in OSI model? The term packet is used to express the encapsulated data that is transmitted and received at the network layer. What is the POP? POP (Post Office Protocol) is a protocol. It is used in email system by client computer to retrieve the mails from e-mail server. Based on network relationship, how many types of network are there? Based on network relationship, there are two types of network peer-to-peer and client/server. What is the Encapsulation? Encapsulation is the process of packing data for transportation. What is a peripheral?

STP cable has an additional layer of insulation on each pair of twisted wires which protects the quality of signals in wires. In positive side STP cable is more reliable. In negative side, it is more expensive in comparison of UTP cable. What are the differences between the single mode fiber optical cable and the multimode fiber optical cable? SMF (Single Mode Fiber) cable uses a single ray of light to carry the signals while MMF (Multi Mode Fiber) cable uses multiple rays of light to carry the multiple signals simultaneously. What is the Crosstalk? Crosstalk is the interference which generates from adjacent wires. What is the distance limit of 10Base2 Ethernet? Theoretically it supports 200 meter distance. Practically it supports only 185 meters. This is because it uses Thinnet coaxial cable which has a distance limitation of 185 meters. That's all for this part. In next part, we will take more networking interview questions with answers. If you have any suggestion, comment or feedback about this article, please mail me.
