System Design — Buzzwords to revise before going for an Interview — Part 1
Key terms to revise before your next technical interview.
Client-Server Model
A client and server networking model is a model in which computers such as servers provide the network services to the other computers such as clients to perform a user based tasks.
Protocols in networking
In networking, a protocol is a standardized set of rules for formatting and processing data. Protocols enable computers to communicate with one another.
TCP vs UDP vs HTTP
HTTP requires a TCP connection, HTTP is an abstraction over TCP.
Overhead of creating UDP connections is much less than TCP connections(because of the concept of handshake in TCP)
UDP — Would be best for Data Steaming services as negligible time is required to form a connection.
TCP- Can be used to form more reliable connections.
HTTP vs gRPC protocols
HTTP protocol uses ASCII characters to communicate between the services/resources, to reduce the latency of the protocol, we can use gRPC protocol instead which uses binary characters to transfer/communicate data.
Latency vs Throughput
In any system, we want minimum latency and maximum throughput.
But what is latency and throughput?
Latency: Time taken between the time at which the response was sent and the time at which the request arrived at the system.
Throughput- Number of requests processed by a system in a unit of time.
