Split 192.168.10.0/24 using a /26 mask (255.255.255.192).
| Subnet | Network address | Usable hosts | Broadcast address |
|---|---|---|---|
| 1 | 192.168.10.0 | 192.168.10.1 to .62 | 192.168.10.63 |
| 2 | 192.168.10.64 | 192.168.10.65 to .126 | 192.168.10.127 |
| 3 | 192.168.10.128 | 192.168.10.129 to .190 | 192.168.10.191 |
| 4 | 192.168.10.192 | 192.168.10.193 to .254 | 192.168.10.255 |
A /26 leaves 6 host bits, giving 2⁶ = 64 addresses per subnet, of which 62 are usable after removing the network and broadcast addresses.
Send a 1,000-byte packet over a 10 Mbps link that is 2,000 km long, with signals travelling at 2 × 10⁸ m/s.
| Delay | Working | Result |
|---|---|---|
| Transmission delay | 8,000 bits ÷ 10,000,000 bits/s | 0.8 ms |
| Propagation delay | 2,000,000 m ÷ 2 × 10⁸ m/s | 10 ms |
| Total (ignoring queuing and processing) | 0.8 + 10 | 10.8 ms |
On long links, propagation delay dominates; on slow links, transmission delay dominates.
TCP sets up a connection in three steps: the client sends SYN with its initial sequence number, the server replies with SYN-ACK acknowledging it and sending its own number, and the client replies with ACK. Data can then flow reliably in both directions, and the connection is closed with FIN and ACK exchanges.

Most lost marks come from subnetting slips and confusing layers.
| Mark-loser | What to do instead |
|---|---|
| Counting network and broadcast addresses as hosts | Usable hosts = 2ʰ − 2 |
| Bytes and bits mixed up in delay problems | Convert bytes to bits (× 8) |
| Protocols placed in the wrong layer | Map each protocol to its layer in a table |
| Confusing TCP and UDP features | Compare reliability, ordering and overhead |
| Lab screenshots without explanation | Explain what each capture or configuration shows |
| Network designs without justification | Explain each device and addressing choice |
Computer networks is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Numerical exams | Correct subnetting, delay, throughput and error-detection calculations |
| Theory questions | Accurate protocol descriptions and comparisons |
| Packet Tracer or GNS3 labs | Working configurations with explained results |
| Wireshark analysis | Correct interpretation of captured packets |
| Network design projects | A justified topology, addressing plan and security measures |
Networking courses use simulation and analysis tools.
| Tool | What it is used for |
|---|---|
| Cisco Packet Tracer | Simulating networks and configuring devices |
| GNS3 | Emulating routers and switches |
| Wireshark | Capturing and analysing packets |
| Command-line tools (ping, traceroute, nslookup) | Testing connectivity and DNS |
| Subnet calculators | Checking your subnetting by hand |
Computer networks is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where computer networks is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | BSc Computer Science and Networking | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | IEEE or Harvard |
| United States | Computer networks courses in CS and IT | Letter grades A–F and a 4.0 GPA scale | IEEE or ACM |
| Australia | Networking and IT degrees | HD, D, C, P at university; ATAR for school leavers | IEEE or Harvard |
| Canada | Computer networks courses | Letter grades or percentages; GPA scales vary by province and university | IEEE or ACM |
| India | BTech, BCA and MCA computer networks papers; GATE CSE | Board exam percentages; university CGPA, often on a 10-point scale | IEEE |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of computer networks help depends on whether it is numerical, theory or lab work, its size and your deadline. A set of subnetting questions costs less than a full network design project. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Student reviews
Used FLN Tutors? Be one of the first to share how it went, in writing or in a short video.
Yes. Tutors explain the protocols, work through numerical problems and help with labs and design projects, within your university's rules.
The OSI model has seven layers and is mainly a teaching reference; the TCP/IP model has four or five layers and describes how the internet actually works.
Decide how many subnets or hosts you need, borrow the required host bits, find the block size, then list each subnet's network, host range and broadcast address.
A /24 has 8 host bits, so 256 addresses and 254 usable hosts.
TCP is connection-oriented and reliable, with ordering and congestion control; UDP is connectionless and faster with less overhead, but does not confirm delivery.
Transmission delay = packet size in bits ÷ link bandwidth in bits per second.
Propagation delay = distance ÷ signal propagation speed.
DNS translates domain names such as example.com into IP addresses that computers use to connect.
Network address translation lets many devices on a private network share one public IP address.
A switch forwards frames within a local network using MAC addresses; a router forwards packets between networks using IP addresses.
Classless inter-domain routing writes networks as an address and prefix length, such as 192.168.1.0/24, allowing flexible subnet sizes.
Each router shares its distance table with neighbours and updates its routes using the Bellman–Ford equation.
Yes. Tutors help you configure devices, troubleshoot connectivity and explain your results.
Yes. Tutors explain filters, protocol fields and what the traffic shows.
A VLAN groups devices into separate logical networks on the same physical switches, improving security and reducing broadcast traffic.
Yes. Tutors help BTech students with GATE CSE-style networking questions.
Tutors work from your course text, for example Kurose and Ross or Tanenbaum, and your notes.
Often, yes, for short problems, depending on tutor availability.
Yes. Tutoring, worked examples and feedback are a normal part of learning. You should use the explanations to understand the method and submit your own work in line with your school's or university's academic integrity rules. See our academic integrity policy.
Yes. Your files and details are used only to help you and are not shared with your school or university. See our privacy policy.
