suppose that a tcp sender is sending segments with 200 bytes of payload. it sends 5 segments with sequence number 100, 300, 500, 700, and 900. suppose the segment with sequence number 500 is lost. what are the ack values that the receiver returns to the sender after each of the 4 received segments are received?
We can record analytics data from our Python code using Segment's Python library. Segment routes our data to any analytics provider we enable on our destinations page after the requests reach its servers.
We can access this library's open-source code on GitHub. Python also has the ability to return a portion of a list starting at the end. To accomplish this, simply place a negative sign (-) before the necessary numbers in the slice command. A source is anything that can feed data into a segment, such as a website, server library, mobile SDK, or cloud application. Data segmentation is the process of taking the data you already have and breaking it up into groups of related data based on the selected parameters so you can use it more effectively in operations and marketing.

you are in the process of configuring an iscsi storage area network (san) for your network. you want to configure a windows server system to connect to an iscsi target defined on a different server system. you also need to define iscsi security settings, including chap and ipsec. which tool should you use?
iSCSI initiator is the tool
What is iSCSI initiator ?
In computer data storage, a SCSI initiator is the endpoint that initiates a SCSI session, that is, sends a SCSI command. The initiator usually does not provide any Logical Unit Numbers. A host computer can transport data to an external iSCSI-based storage array using an Ethernet network adapter across an IP network by using an Internet Small Computer System Interface (iSCSI) initiator, which can be either software or hardware. For data transmission to the storage device, also referred to as an iSCSI target, the iSCSI initiator creates the input/output (I/O) command sequence.
Hardware-based iSCSI initiators are much less frequent than software-based ones. The Small Computer System Interface (SCSI) I/O command set is mapped to TCP/IP for usage by the iSCSI storage system by a software iSCSI initiator, which is often a component of the server operating system. A dedicated host-based network interface card (NIC) with resources built-in to handle the iSCSI and TCP/IP processing tasks is referred to as a hardware iSCSI initiator. Because servers now have more potent computing cores, they no longer require a NIC-based TCP/IP offload engine (TOE). When a server is booted from a local disc, a hardware iSCSI initiator may still be beneficial for data protection or security if the card includes built-in encryption capabilities.

For the subsequent steps, the memory-fetched opcode is decoded and relocated to the relevant registers.
