Deadlock

A deadlock is a situation in which two computer programs sharing the same resource are effectively preventing each other from accessing the resource, resulting in both programs ceasing to function.

The earliest computer operating systems ran only one program at a time. All of the resources of the system were available to this one program. Later, operating systems ran multiple programs at once, interleaving them.


Thanks

Cache Memory

Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory.

Cache memory is sometimes described in levels of closeness and accessibility to the microprocessor. An L1 cache is on the same chip as the microprocessor. (For example, the PowerPC 601 processor has a 32 kilobyte level-1 cache built into its chip.) L2 is usually a separate static RAM (SRAM) chip. The main RAM is usually a dynamic RAM (DRAM) chip.

Hello,

Dedicated hosting service

A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone else. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc. There is also another level of dedicated or managed hosting commonly referred to as complex managed hosting. Complex Managed Hosting applies to both physical dedicated servers, Hybrid server and virtual servers, with many companies choosing a hybrid (combination of physical and virtual) hosting solution. There are many similarities between standard and complex managed hosting but the key difference is the level of administrative and engineering support that the customer pays for – owning to both the increased size and complexity of the infrastructure deployment. The provider steps in to take over most of the management, including security, memory, storage and IT support. The service is primarily proactive in nature. [1] Server administration can usually be provided by the hosting company as an add-on service. In some cases a dedicated server can offer less overhead and a larger return on investment. Dedicated servers are most often housed in data centers, similar to colocation facilities, providing redundant power sources and HVAC systems. In contrast to colocation, the server hardware is owned by the provider and in some cases they will provide support for your operating system or applications.
Using a dedicated hosting service offers the benefits of high performance, security, email stability, and control.[2] Due to the relatively high price of dedicated hosting, it is mostly used by websites that receive a large volume of traffic.

How to register a new domain for free


Every website has a specific name to identify it on the World Wide Web. Like your home address, it consists of different parts. The domain name has to be unique and lead to only one specific website. That is why you have to check first if your desired domain name is free and not already claimed. Any web address begins with „www“.

This is an abbreviation for World Wide Web and is the gateway to the internet. Nowadays, domain names do not necessarily have to have a „www“ in front because web browsers will recognize it automatically. The next part, the Second Level, is the most important recognition factor – the domain name. Think of a domain name that best reflects the content and subject of your website! The last part is the Top Level Domain, and it can be generic (.net, .com, .org) or geographic (.us, .ca, etc.). You can only register a free domain name that has not already been claimed.


Thanks
Ameen

ICMP is Internet Control Message Protocol, a network layer protocol of the TCP/IP suite used by hosts and gateways to send notification of datagram problems back to the sender. It uses the echo test / reply to test whether a destination is reachable and responding. It also handles both control and error messages.

hii,

Simple Loop Prevention Protocol (SLPP) in computer networking is a layer 2 protocol invented by Nortel (now acquired by Avaya) to protect against network loops. SLPP uses a small hello packet to detect a network loops. The SLPP protocol checks packets from the originating switch and the peer switch in a SMLT configuration. Sending hello packets on a per VLAN basis allows SLPP to detect VLAN based network loops for un-tagged as well as tagged IEEE 802.1Q VLAN link configurations. Once a loop is detected, the port is shutdown.

Thanks,
swetha.

Round Trip Time

Round-trip time (RTT), also called round-trip delay, is the time required for a signal pulse or packet to travel from a specific source to a specific destination and back again. In this context, the source is the computer initiating the signal and the destination is a remote computer or system that receives the signal and retransmits it.

Thanks

 RPM (Red Hat Package Manager) features.


RPM is a package managing system (collection of tools to manage software packages).

The main Features of RPM:

    RPM can verify software packages.
    RPM can be served as a powerful search engine to search for software’s.
    Components, software’s etc can be upgraded using RPM without having to reinstall them
    Installing, reinstalling can be done with ease using RPM
    During updates RPM handles configuration files carefully, so that the customization is not lost.


Thanks

DHCP scope

DHCP reconciliation is a process in which you manually initiate the DHCP database consistency check. While reconciling, the Windows Server 2012 DHCP server checks if the DHCP database is consistent with the Windows registry, and no errors or issues are present in the database.

Wide Area Network

A wide area network (WAN) is a network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, national or international boundaries) using leased telecommunication lines. Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations.

In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet can be considered a WAN as well, and is used by businesses, governments, organizations, and individuals for almost any purpose imaginable.

Thanks

Bit Stuffing

Bit stuffing is the process of inserting noninformation bits into data to break up bit patterns to affect the synchronous transmission of information. It is widely used in network and communication protocols, in which bit stuffing is a required part of the transmission process. Bit stuffing is commonly used to bring bit streams up to a common transmission rate or to fill frames. Bit stuffing is also used for run-length limited coding.

Thanks

 ICMP (Internet Control Message Protocol) is a message control and error-reporting protocol between a host server and a gateway to the Internet. ICMP uses Internet Protocol (IP) datagrams, but the messages are processed by the IP software and are not directly apparent to the application user.
