DNS (Domain Name System) translates domain names into IP addresses, enabling users to access websites using easy-to-remember names.

• DNS acts like a phonebook for the internet, mapping domain names (e.g., www.example.com) to IP addresses (e.g., 192.0.2.1).

• It consists of a hierarchy of servers, including root servers, TLD servers, and authoritative name servers.

• DNS caching improves performance by storing previously resolv...read more

DHCP (Dynamic Host Configuration Protocol) automates IP address assignment in networks, simplifying device connectivity.

• DHCP assigns IP addresses dynamically, reducing manual configuration.

• It operates on a client-server model, where clients request IPs from a DHCP server.

• DHCP can provide additional network configuration, such as subnet mask and default gateway.

• Example: When a laptop connects to Wi-Fi, DHCP assigns it a...read more

Outlook configuration involves setting up email accounts, preferences, and connectivity settings in Microsoft Outlook.

• Add an email account: Use the 'Account Settings' to add a new email account by entering the email address and password.

• Configure server settings: Input incoming (IMAP/POP) and outgoing (SMTP) server details for proper email delivery.

• Set up signatures: Create personalized email signatures for professiona...read more

There are several types of memory in computing, including volatile and non-volatile memory, each serving different purposes.

• Volatile Memory: Requires power to maintain data (e.g., RAM).

• Non-Volatile Memory: Retains data without power (e.g., SSD, HDD).

• Cache Memory: A small-sized type of volatile memory that provides high-speed data access to the CPU.

• Read-Only Memory (ROM): Non-volatile memory used to store firmware.

• Flash...read more

BitLocker is a disk encryption feature in Windows that protects data by encrypting entire volumes.

• BitLocker uses AES encryption to secure data on hard drives.

• It can be enabled on Windows Pro, Enterprise, and Education editions.

• Users can unlock BitLocker drives using a password, smart card, or recovery key.

• BitLocker can protect both internal and external drives, including USB flash drives.

• It integrates with Active Direc...read more

OST files are offline storage files for Outlook, while PST files are personal storage files for archiving emails.

• OST (Offline Storage Table) files allow users to work offline and sync changes when connected to the server.

• PST (Personal Storage Table) files are used to store emails, contacts, and calendar events locally on a user's computer.

• OST files are typically used with Microsoft Exchange accounts, while PST files ca...read more

An IP address is a unique numerical label assigned to each device connected to a computer network.

• IP address stands for Internet Protocol address.

• It is used to identify and locate devices on a network.

• IP addresses can be either IPv4 (32-bit) or IPv6 (128-bit) format.

• IPv4 example: 192.168.0.1

• IPv6 example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

Routers connect multiple networks and determine the best path for data packets, while switches connect devices within a network.

• Routers operate at the network layer (Layer 3) of the OSI model, while switches operate at the data link layer (Layer 2).

• Routers use IP addresses to forward packets between networks, while switches use MAC addresses to forward packets within a network.

• Routers can connect different types of net...read more

DHCP (Dynamic Host Configuration Protocol) is a network protocol that enables devices to obtain IP addresses and other network configuration settings automatically.

• DHCP is used to assign IP addresses dynamically to devices on a network.

• It allows devices to request and obtain IP addresses, subnet masks, default gateways, and DNS server addresses.

• DHCP operates on a client-server model, where DHCP servers manage and distr...read more

The OSI model does not include any Leary.

• The OSI model is a conceptual framework that defines the functions of a network protocol.

• It consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• None of these layers include any reference to Leary.

• Leary is not a term or concept associated with the OSI model.

The OSI model is a conceptual framework that standardizes the functions of a communication system into seven layers.

• The Physical layer is responsible for the physical transmission of data.

• The Data Link layer provides error-free transmission of data frames between nodes on a network.

• The Network layer handles routing and logical addressing.

• The Transport layer ensures reliable delivery of data between end systems.

• The Sess...read more

FQDN stands for Fully Qualified Domain Name.

• FQDN is a complete and unique address that specifies the exact location of a domain on the internet.

• It consists of the host name, domain name, and top-level domain (TLD).

• For example, www.example.com is an FQDN where 'www' is the host name, 'example' is the domain name, and 'com' is the TLD.

OST and PST are file formats used by Microsoft Outlook to store email data locally on a user's computer.

• OST (Offline Storage Table) is a file format used by Outlook to store a copy of mailbox data on the local computer.

• PST (Personal Storage Table) is a file format used by Outlook to store email messages, contacts, calendar items, and other data locally.

• OST files are typically used for Exchange accounts to allow offline...read more

DHCP is a network protocol that assigns IP addresses to devices on a network, while DNS translates domain names to IP addresses.

• DHCP stands for Dynamic Host Configuration Protocol

• DHCP automatically assigns IP addresses to devices on a network

• DNS stands for Domain Name System

• DNS translates domain names (e.g. www.google.com) to IP addresses (e.g. 172.217.3.206)
