1. What is bandwidth?

   • Bandwidth is the amount of data that can pass between two network devices per second(bits per second).
     • IP address- A unique string of Numbers separated by full stops using the Internet protocol to communicate
     • Domain name/ address- Domain names are used to identify one or more IP address. Words and letters.
       • Mac address- Media access control- Is a hardware identification number that uniquely identifies devices

2. What is a Client-sever network?

   • A client sever network is when a main computer server is accsessed from multiple client computers
   • What is a Peer-to-peer network?
     • All computers within a peer-to-peer networks act as both client and server
       • Security permissions are shared across the network

3. What are the different data types?

   • Integer-whole numbers only
   • Real(or float)-Numbers that have a decimal part
   • Boolean-Can only take one of two values, usually TRUE or FALSE
   • Character-A single letter, number symbol
   • String- Used to represent text, is a collection of characters

4. Networks layers

   • Application layer- Turning data into websites and other application. HTTP, FTP,SMTP
     • Transport layer- Controlling data flow- eg. splitting data into data packets and checking packets are correctly sent and developed
       • Internet/Network layer- Making connections between networks,directing packets and handling traffic used by routers
         • Data link layer- Data link layer passing data over a physical network. Responsible for how bits are sent over as electrical signals over cables, wireless and other hardware

5. Wireless Connectivity

   • 2.4GHZ
     • Is the standard frequency, traffic is high causing interference
       • Has 3 bands, transfers data at a slower but have a long range
   • 5GHZ
     • Has 25 bands, transfers data at a faster rate, but has a shorter range
