CPU full from RAM full form

• CPU stands for Central Processing Unit

• RAM stands for Random Access Memory

• When the RAM is full, it can cause the CPU to become overloaded

• This can lead to slow performance and system crashes

Types of motherboards include ATX, Micro ATX, Mini ITX, and Extended ATX.

• ATX (Advanced Technology eXtended) is the most common form factor for desktop motherboards.

• Micro ATX is a smaller form factor than ATX, often used in compact desktops.

• Mini ITX is even smaller than Micro ATX, commonly used in small form factor PCs.

• Extended ATX is a larger form factor than ATX, providing additional expansion slots and features.

Active Directory is a directory service developed by Microsoft for Windows domain networks.

• Centralized database for managing network resources

• Stores information about users, computers, and other network objects

• Allows for authentication and authorization of users

SSD is faster, more durable, and more expensive than HDD.

• SSD uses flash memory to store data, while HDD uses spinning disks.

• SSD has faster read/write speeds compared to HDD.

• SSD is more durable as it has no moving parts, while HDD can be prone to mechanical failure.

• SSD is more expensive per gigabyte compared to HDD.

• Examples: SSD - Samsung 970 EVO, HDD - Seagate Barracuda

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

A server is a computer or software program that provides functionality or resources to other computers, known as clients, over a network.

• Servers store and manage data, files, applications, and services for clients to access.

• They can provide email services, host websites, store files, and more.

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

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

• DNS is like a phone book for the internet, translating human-readable domain names (like google.com) to machine-readable IP addresses (like 172.217.3.206)

• DNS helps users access websites and other online services by resolving domain names to IP addresses

• DNS servers store records of domain names and their corresponding IP addresses
