   • Latency vs Jitter in Computer Networks

     There are two vital concepts in the world of networking and telecommunications that are used frequently, latency and jitter. There are, on the other hand, two separate components of data transmission efficiency.

     Latency

     It refers to the time it takes for data to go from the origin to the destination. This delay encompasses various factors such as:

     Propagation delays: Time the signal takes to propagate through the medium. It...

     • Processing Delays: The time required for data to be processed by network devices like routers and switches.
     • Queueing delays: Time spent in a queue waiting to be transmitted before reaching the link to the destination host.
     • Transmission delays: time it takes to push the packet’s bits into the wire.
     • Propagation delays: Time the signal takes to propagate through the medium. It would be a signal through an optic cable.

   • #define vs #undef in C language

     In this article, we will discuss the difference between #define and #undef pre-processor in C language.

     What are Pre-Processor Directives?

     • Pre-processor is a program that performs before the compilation.
     • It only notices the # started statement.
     • # is called preprocessor directive.
     • Each preprocessing directive must be on its own line.
     • The word after # is called the preprocessor command.

     #define

     The #define directive defines an identifier and a character sequence (a set of characters) that will be substituted for the identifier each time it is encountered in the source file.

     Syntax

     #define macro-name char-sequence

     The identifier is referred to as a macro name and the replacement process is called macro expansion.

     For example,

     #define PI 3.14

     Here, PI is the macro name and 3.14 is the char-sequence.

     Examples of #define Directive

   • In computer science, what is NOT a formal language?

     Top Answer

     Answered Jun 08, 2024 · 5 votes

     Let me get to your question first. A good non-example of a formal language are the natural languages. English and Slovene are examples. So are Tagalog and Tarifit Berber. Unfortunately linguists don't seem to have a definition of natural language that all would agree upon.

     Noam Chomsky famously tried to model natural language using context-free gammars in his 1956 paper Three Models for the Description of Language. He invented (or discovered, if you prefer) them in that paper; although he didn't call them that; while they weren't useful to model the English language, they revolutionized computer science.

     Formally, a formal language is just a set of strings over a finite alphabet. That's it.

     Examples include all valid C programs, all valid HTML files, all valid XML files, all strings of "balanced" parentheses (e.g. (), ()(), ((()))()(()), ...), the set (codes under some encoding) of all deterministic Turing machines that always halt, the set of all simple graphs that can be colored with k-colors (actually their codes under some encoding), the set of all binary strings that end and begin with a 1, etc.

     Some are easy to recognize using regex (or, equivalently, DFA); some are impossible to recognize using DFA's, but can be recognized using PDA (or, equivalently, can be described with a context-free grammar); other's don't admit such a description, but can be recognized by a Turing machine; some aren't recognizable even by a Turing machine (called uncomputable).

     This is why the definition is so useful. Many things we encounter in CS evey day can be cast in terms of formal languages.

     For a good introduction to the subject, I highly recommend the superb book Introduction to Automata Theory, Languages, and Computation by Hopcroft et al.

   • Latency in Snowflake Account Usage Views

     Top Answer

     Answered Oct 03, 2022 · 0 votes

     Data latency

     Due to the process of extracting the data from Snowflake’s internal metadata store, the account usage views have some natural latency:

     • For most of the views, the latency is 2 hours (120 minutes).
     • For the remaining views, the latency varies between 45 minutes and 3 hours.

     For details, see the list of views for each schema (in this topic). Also, note that these are all maximum time lengths; the actual latency for a given view when the view is queried may be less.

     "Does the latency, let's say for Query History mentioned to be 45 min, mean it might take 45 min for a query to pull result out of Account Usage view or does it mean it might take time for data to be available in Account Usage view?"

     The terms latency refers to the time until the data will be available in Account Usage view.

     It does not mean that query SELECT * FROM SNOWFLAKE.ACCOUNT_USAGE.<some_view> takes 45 minutes to execute.

   What is the difference between context switch and dispatch latency?

   • the kernel decides it has nothing better to do so it returns to user-space, taking another 10 nanoseconds. Here, the context switch time would be 40 nanoseconds, but the dispatch latency (as defined by the book's author) would be 100 nanoseconds. "Context Switch" is a process. "Dispatch Latency" is a latency, a.k.a. time.

   What does high latency mean?

   • High latency can indicate network congestion or long physical distances between the client and server. Response time is the time between a client sending a request and receiving a response. It is the sum of round trip latency, processing delays and queueing delays (normally due to CPU's parallelism limitations).

   • Including the time it takes for a byte of data to make it from the responding computer back to the requesting computer. It is generally measured as a round trip delay. Disk latency is the time it takes from the moment a computer, usually a server, receives a request, to the time the computer returns the response.
