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)

Active Directory is a directory service developed by Microsoft that stores information about network resources and enables centralized management.

• Active Directory is used to manage and organize users, computers, and other network resources in a Windows domain.

• It provides a hierarchical structure for organizing objects, such as users, groups, and computers.

• Active Directory enables centralized authentication and authoriz...read more

DHCP stands for Dynamic Host Configuration Protocol. It is a network protocol that automatically assigns IP addresses to devices on a network.

• DHCP is used to manage and distribute IP addresses in a network.

• It allows devices to obtain IP addresses dynamically instead of manually configuring them.

• DHCP also provides additional network configuration information like subnet mask, default gateway, and DNS server addresses.

• It...read more

Default gateway is the IP address of the router that connects a local network to the internet.

• Default gateway is a network device that acts as an access point for traffic between the local network and the internet.

• It is usually the IP address of the router that connects the local network to the internet.

• All outgoing traffic from the local network is sent to the default gateway for further routing.

• Default gateway allows...read more
