1. What is the difference between a switch and a router? Ans: Switch is a device which is used to connect multiple computer’s with in a single network and allow to transfer data between them. Router is used to connect multiple network’s and route between them based on IP addresses. 2. What is the purpose of the subnet mask in IP addressing? Ans: A subnet Mask is used in IP addressing to divide a large network into a smaller subnetwork, subnet mask help to determine for which part of IP address is designated for network portion and which part is for host portion 3. How does TCP/IP work and what are its key components? Ans: TCP/IP is a set of protocols that allow communication between devices over a network. Its key components are: IP (Internet Protocol): responsible for routing data packets to their destination. TCP (Transmission Control Protocol): responsible for reliable data transfer by dividing data into segments, retransmitting lost packets and reassembling the data at the receiver. DNS (Domain Name System): responsible for converting human-readable domain names into IP addresses. HTTP (HyperText Transfer Protocol): responsible for transmitting data over the web. FTP (File Transfer Protocol): responsible for transferring files over a network. These protocols work together to transfer data between devices over the internet or other networks. 4.

Cyber security is the metaphorical city that never sleeps so its worker bees need to stay tuned to the buzz to avoid missing valuable developments that may threaten the security of data. People Skills Soft skills are just as important as the technical expertise required for cyber security jobs as much of what poses a threat to data security are the people to whom the data belongs. These are also the literal gatekeepers to a great deal of the data being accessed by cyber criminals. Data Analytics To work in cyber security you essentially have to be a data whisperer. The bulk of what cyber security rests on is analysing large amounts of data so individuals with a scientific mind who are able to funnel data from multiple sources and unscramble it into something that...
