There are two main types of RAM: DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory).

• DRAM (Dynamic Random Access Memory) - most common type, used in computers for main memory

• SRAM (Static Random Access Memory) - faster and more expensive than DRAM, used in cache memory

• Other types include SDRAM (Synchronous Dynamic Random Access Memory), DDR (Double Data Rate) RAM, and DDR2/3/4 RAM

Domain Naming System (DNS) is a system that translates domain names to IP addresses.

• Examples include web servers like Apache, email servers like Microsoft Exchange, and file servers like Windows Server.

Topology refers to the arrangement of different elements in a network.

• Topology defines how devices are connected in a network

• Common topologies include bus, star, ring, and mesh

• Each topology has its own advantages and disadvantages

• Topology affects the performance, scalability, and fault tolerance of a network
