Transfer Data from one computer to another computer using Lan cable

Computer, Education, Tutorial, Uncategorized
Steps for  Send files from one computer to another Step 1 Connect both computer with a LAN cable. Step 2 OK, now you have to enable sharing option on both computers. Go to Control Panel > Network and Internet > Network and Sharing Center > Advanced sharing settings. And make sure you turn on network detection and turn off password protection off. Enable sharing optionStep 3 Bring both the computers on the same network. 1. Open Control Panel > Network and Internet > Network Connections. 2. You will see Local Area Connection. 3. Right-click it and go to its properties. 4. You will see TCP/ ivp4 option there and select its properties.   5. Select this use the following ip address Put the following value on 1st computer Ip address 192.168.1.1    …

Serial port and parallel port

Computer, Education, Hardware, Tutorial, Uncategorized
Serial port and Parallel port Serial port Serial ports are generally built into the mother board, which is why the connectors behind the casing and connected to the mother board by a wire cable can be used to connect an exterior element. Serial connectors generally have 9 or 25 pins and take the following form (DB9 and DB25 connectors respectively): A personal computer generally has between one and four serial ports. Parallel port Parallel data transmission involves sending data simultaneously on several channels (wires). The parallel ports on personal computers can be used to send 8 bits (one octet) simultaneously via 8 wires. The first two-way parallel ports allowed for speeds of 2.4Mb/s. Enhanced parallel ports have been developed however to achieve higher speeds: The EPP (Enhanced Parallel Port) achieves…

Circuit Cross-Connects Overview

Education, Networking, Telecom, Tutorial, Uncategorized
Circuit cross-connect (CCC)  allow you to configure transparent connections between two circuits, where a circuit can be a Frame Relay data-link connection identifier (DLCI), an Asynchronous Transfer Mode (ATM) virtual circuit (VC), a Point-to-Point Protocol (PPP) interface, a Cisco High-level Data Link Control (HDLC) interface, or a Multiprotocol Label Switching (MPLS) label-switched path (LSP).   CCC can ONLY use RSVP as MPLS transport, in addition each CCC connection has its own dedicated RSVP-signalled LSP associated, the transport label cannot be shared between multiple connections. Using CCC, packets from the source circuit are delivered to the destination circuit with, at most, the Layer 2 address being changed. No other processing, such as header checksums, time-to-live (TTL) decrementing, or protocol processing, is done. To connect interfaces of the same type, use CCC.To…

Network Functions Virtualization

Education, Networking, Telecom, Tutorial, Uncategorized
Network Functions Virtualization  NFV (Network Functions Virtualization) is virtualizing Layer 4-7 functions such as firewall or IDPS, or even load balancing (application delivery controllers).  NFV (Network Functions Virtualization) uses best practices as base policies and configurations for different network elements. If you have a specific tunnel you’re punching through the infrastructure, you can add a firewall or IDS/IPS to just that tunnel. The popular functions for this are firewalls and IDS/IPS systems from companies like PLUMgrid or Embrane. NFV (Network Functions Virtualization) runs on high-performance x86 platforms, and it enables users to turn up functions on selected tunnels in the network. The goal is to allow people to create a service profile for a VM, or flow, and leverage x86 muscle to build an abstraction on top of the network (the tunnel)…

Network Virtualization

Education, Networking, Telecom, Tutorial, Uncategorized
Network Virtualization Network virtualization literally tries to create logical segments in an existing network by dividing the network logically at the flow level (it is similar to partitioning a hard drive).  NV is an overlay; it’s a tunnel. Rather than physically connecting two domains in a network, NV creates a tunnel through the existing network to connect two domains. NV is valuable because it saves administrators from having to physically wire up each new domain connection, especially for virtual machines that get created. This is useful because administrators don’t have to change what they have already done. They get a new way to virtualize their infrastructure and make changes on top of an existing infrastructure. NV runs on high-performance x86 platforms. The goal is to allow people to move VMs…

Software Defined Networking (SDN)

Education, Telecom, Tutorial, Uncategorized
Software Defined Networking SDN uses canned processes to provision the network. For example, instead of building a network tap using an appliance, users should be able to program the network when they want to build a tap. SDN makes the network programmable by separating the control plane (telling the network what goes where) from the data plane (sending packets to specific destinations). It relies on switches that can be programmed through an SDN controller using an industry standard control protocol, such as OpenFlow. SDN changes the physical network, and therefore is really a new externally driven means to provision and manage the network. A use case may involve moving a large "elephant flow" from a 1G port to a 10G port, or aggregation of lot of “mice flows” to one…

What is the role of the CPU?

Computer, Education, Tutorial, Uncategorized
The CPU is the core component of any computer, and its main function is to control and calculate binary calculations. The abbreviation CPU stands for central processing unit. The CPU is an important piece of hardware that performs the instructions of a computer program. All instructions given by the user have to go through the CPU. It performs input and output operations as well as basic arithmetical and logical operations. A typical CPU consists of a number of components, including the arithmetic logic unit, the control unit and the cache. The CPU is located on the motherboard of a computer.

Central processing unit

Computer, Education, Tutorial, Uncategorized
A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. Traditionally, the term "CPU"to as a processor, central processor, or microprocessor, the CPU (pronounced sea-pea-you) is the Central Processing Unit of the computer. A computer's CPU handles all instructions it receives from hardware and software running on the computer. The CPU is often referred to as the brain of the computer. However, it is more appropriate to refer to software as the brain and the CPU as a very efficient calculator. A CPU is really good with numbers, but if it wasn't for the software it wouldn't know how to do anything else.
