What to know about Network Programming
RAM tests your ability to identify, install, and troubleshoot memory types, speeds, and configurations for PCs.
Identifying DDR3 vs DDR4 vs DDR5 physical and electrical differences
Matching RAM speed (MHz) to motherboard and CPU support
Calculating total memory capacity from module size and slots
Troubleshooting common RAM errors like beep codes and blue screens
Why learners struggle
Why Network Programming questions are commonly missed
RAM questions are commonly missed because learners confuse physical form factors (DIMM vs SO-DIMM) and fail to distinguish between memory speed (MHz) and latency (CL).
- ·DIMM vs SO-DIMM — desktop vs laptop form factor confusion
- ·DDR3 vs DDR4 vs DDR5 — notch position and voltage differences
- ·MHz vs CL — speed vs latency trade-offs in performance
- ·Single-channel vs dual-channel — bandwidth impact misconception
- ·ECC vs non-ECC — error correction support in servers vs desktops
- ·32-bit vs 64-bit — maximum addressable RAM limit
Watch out for
Common Network Programming exam traps
- ▸Confusing DDR3 and DDR4 notch positions and voltage requirements
- ▸Assuming dual-channel requires identical size modules only
- ▸Mixing ECC and non-ECC RAM in a single system
- ▸Forgetting that 32-bit OS limits usable RAM to 4 GB

You are configuring a server to handle high-concurrency requests. Why is it preferable to use the select.select() module over a simple blocking recv() loop?
Medium2In a multi-threaded Python server, why is it discouraged to share a single socket object across multiple threads without synchronization?
Hard3Which TWO of the following are true regarding the socket.shutdown() method?
Medium4Which of the following is the correct way to close a socket object in Python?
Easy5Which method should a developer use to retrieve the IP address and port of the remote peer connected to a TCP socket?
Easy6Which TWO of the following are necessary to connect a TCP client to a server?
Easy7Which THREE of the following options can be used with socket.setsockopt()?
Hard8What is the effect of setting a socket to non-blocking mode using socket.setblocking(False)?
Easy9Which THREE of the following are true regarding the use of the socket module in Python?
Hard10Which TWO of the following are differences between TCP and UDP?
Easy11Why is the socket.socket() constructor typically called with socket.AF_INET and socket.SOCK_STREAM for a standard web server?
Medium12You need to detect if a client has disconnected from your TCP server. What is the standard behavior of recv() when the peer performs a clean shutdown?
Medium13Which of the following describes the behavior of TCP_NODELAY?
Hard14Which function in the socket module is used to convert a 32-bit integer from host byte order to network byte order?
Easy15Which THREE of the following are valid ways to send or receive data?
Easy16Which TWO of the following are common issues when using select.select()?
Hard17What is the purpose of the socket.recvfrom() method?
Easy18You are using socket.socket(socket.AF_INET, socket.SOCK_DGRAM). You attempt to send 10,000 bytes via sendto(). Why might the operation raise an OSError?
Hard19Which TWO of the following methods are typically used on a TCP server socket?
Medium20When handling TCP streams, why might recv(1024) return fewer than 1024 bytes even if the sender sent more?
Hard21When using select.select(inputs, outputs, exceptions), what does the 'outputs' list signify?
Hard22You are building an application using SSL/TLS. Which module must be used to wrap a standard socket to provide encrypted communication?
Medium23When using socket.setsockopt(), which option is required to immediately reuse a port that is currently in a TIME_WAIT state after a server restart?
Hard24Which THREE of the following are valid address families or socket types used with the Python socket module?
Easy25You are configuring a socket timeout. What happens if you call socket.settimeout(5.0) and the operation exceeds 5 seconds?
Medium26What is the significance of the SO_BROADCAST option in a UDP socket?
Medium27In a Python TCP server, what is the primary purpose of the backlog parameter in the listen(backlog) method?
Easy28When implementing a custom application protocol over TCP, how should you handle message framing?
Hard29You are writing a UDP server. What is the main disadvantage of using UDP for high-volume data transmission compared to TCP?
Medium30You are designing a cross-platform network application. Why is it recommended to use socket.getaddrinfo() instead of socket.gethostbyname()?
Medium31Which THREE of the following socket attributes or methods are relevant to managing socket timeouts?
Medium32Which socket method is used to bind a socket to a specific address and port?
