What is LMC ???

The little man computer (LMC) is a simulator which consists of many of the basic features which would be available in a modern computer.

The phrase LMC is used to represent the role of the CPU whereby the littlem man fetches the instructions stored in RAM, decodes them and then executes them.

What is CSS ???

Cascading Style Sheet (CSS) is used to style the HTML elements.

Before the use of CSS it would be quite common to see developers using attributes which were embedded within the HTML tags to style the pages.

The problem with this was that to change the appearance the of a site the change would have to be made in everypage it was used - i.e. a change to the footer or header whih took time. Insted creating a separate style sheet is more convenient where the styles for the elements can be set and simply included in the HTML where required.

Advantages include:

> Reusability - CSS can be reused in multiple HTML pages where consistency for a particular design is required.

> Compatibility − Style sheets are optimized for displaying content on more than one device - i.e. for different screen sizes the sizing and positioning of images and text can be modified to better suit the usability on smaller or larger devices.

What is a constant ???

A constant is similar to a variable in the sense that it too can store data in memory, but differs in that unlike a variable can change a constant, well has to stay the same throughout a program.

Often, the phrase 'immutable' will be used with constants - and it simply means that the value cannot be changed whilst the program is running.

The way in which a constant is declared varies language by language i.e. in C # the keyword 'const' can be used before the name of the constant.

However, in some programming languages such as Python there is no predefined way of declaring a constant and hence in this case it would be good etiquette to take the follwing approach:

> Name the varibale in all caps

> Add a comment above the variable to indicate that it is a constant and that it shouldn't be changed whilst the program is running.

What is a variable ???

A variable is a medium in which we can store data which may be accessed/modified later on in a program.

It is good habbit that when naming variables that a descriptive and useful name is provided - for the programmer to understand what exactly data the variable is storing.

The main role of a variable is to provide a mean of being able to store data in memory whilst being able to manipulate its value throughout the program.

High vs low level language !!!

High level language is one that can be easily understood by the programmer allowing them to be easily converted from an algorithm into program code.

Low level language is machine level code that is understood by computers they literally express the command to be executed in a way that is difficult for humans to interpret.

Examples of high level:

> C #
> Python

Examples of low level:

> Assembly language
> Machine code

What makes a safe password ???

The security of your data online is kept safe by one key measure your password, so it's important whilst you keep it memorable but also secure.

A good password would include the following:

> At least one uppercase letter

> At least one lowercase letter

> At least 10 characters in total

> At least one number or symbol

It is a bit habbit to have a password that can be easily onbtained such as your DOB, pet name, nickname etc...

Whilst it may be tempting it's often better to use separate passwords for different services and accounts - so if your password does get hacked they can't take advantage of the rest of your services.

What is HTML ???

Hypertext markup language (HTML) and is the standard markup language that is used when creating websites.

Using HTML we can structure a web page which is achieved in itself by using tags and elements.

HTML and CSS are often used side by side, with CSS we can style our website to our particular requirements.

Can you define coding ???

Coding is a way how we as humans are able to communicate with computer systems.

Code itself is simply the set of instructions which tells the computer what to do and is written by a porgrammer.

Eveywhere we look we are surrounded by code: the websites we visit, the apps we donwnload and even the videos we watch are all built upon some form of code which makes it possible for us to interact with.

What is a compiler ???

A compiler is responsible for converting high level code (code understood by humans) to low level code (code that is understood by machines).

The compiler reads the code line by line checking for any syntax errors or structural errors.

There are 4 main stages:

1) Lexical analysis - which incudes:

> Removing comments / white space
> Optimise code

2) Syntax anlysis - which includes:

> Check code follows programming language rules
> Optimise code

3) Semantic analysis - which includes:

> Checks code is valide within given context of program
> Optimise code

4) Code generation - which includes:

> Creates object code
> Optimise code
