Welcome to what does it Mean

Latency is when a data packet is transmitted and returned back to its source, the total time for the round trip is known as latency. Latency refers to time interval or delay (time) when a system component is waiting for another system component to do something. Latency = delay or the amount of time it takes to send information from one point to the next point. Example Bandwidth is like the size of a pipe of how wide or narrow the pipe is and Latency is like the amount that flows through a pipe in other words it come down to the speed which is the combination of both bandwidth and Latency to determines your speed. 

Bandwidth is the rate of data transfer, bit rate or throughput, measured in bits per second (bit/s). The more bandwidth a data connection has, the more data it can send and receive at one time. Bandwidth can be compared to the amount of water that can flow through a water pipe. The bigger the pipe, the more water can flow through it at one time. Bandwidth works on the same principle. So, the higher the capacity of the communication link, or pipe, the more data can flow through it per second. 

Jitter, or Network Jitter, is the variance in time delay in milliseconds (ms) between data packets over a network. It is a disruption in the normal sequence of sending data packets. The technical term for jitter is “packet delay variance”.

  Packet loss occurs when one or more packets of data travelling across a network fails to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, or network congestion. Packet loss is measured as a percentage of packets lost with respect to packets sent. The Transmission Control Protocol detects packet loss and performs retransmissions to ensure reliable messaging.

 Network Packet is a formatted unit of data carried by a packet-switched network. A packet consists of control information and user data, which is also known as the payload. Control information provides data for delivering the payload, for example: source and destination network addresses, error detection codes, and sequencing information. Typically, control information is found in packet headers and trailers.

Network Header In Information technology, header refers to supplemental data placed at the beginning of a block of data being stored or transmitted. In data transmission, the data following the header is sometimes called the payload or body.

  Secure Access Service Edge (SASE) is a network architecture that combines VPN and SD-WAN capabilities with cloud-native security functions such as secure web gateways, cloud access security brokers

 Denial-Of-Service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.  

Distributed Denial-Of-Service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. 

Secure Access Service Edge, or SASE (pronounced “sassy”), is an emerging cybersecurity concept

SASE is the convergence of wide area networking, or WAN, and network security services like CASB, FWaaS and Zero Trust, into a single, cloud-delivered service model. 

Cloud Access Security Broker (CASB) are cloud security solution platforms deployed to protect organizations' critical and sensitive data. (CASB) is a visibility and control point that secures cloud applications, delivering data protection and threat protection services to prevent leakage of sensitive data, stop malware and other threats 

Zero Trust instead of assuming everything behind the corporate firewall is safe, the Zero Trust model assumes breach and verifies each request as though it originates from an open network. Regardless of where the request originated

Zero Trust Network Access (ZTNA) is an IT security solution that provides secure remote access to any organization’s applications, data, and services based on a clearly defined access control policy.

Next Generation Firewall (NGFW) is a part of the third generation of firewall technology, combining a traditional firewall with other network device filtering functions, such as an application firewall using in-line deep packet inspection (DPI), an intrusion prevention system (IPS). Other techniques might also be employed, such as TLS/SSL encrypted traffic inspection, website filtering, QoS/bandwidth management, antivirus inspection and third-party identity management integration (i.e., LDAP, RADIUS, Active Directory).

Secure Web Gateway (SWG) is a web security solution that provides safety against cyberthreats and virus infections by analyzing web/ internet traffic, inspecting web requests, comparing them to defined polici
