Q. What is computer network? Describe various networks
A computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of users. Networks are commonly categorized based on their characteristics.
A computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of users. Networks are commonly categorized based on their characteristics.
Different types of networks are distinguished based on their size, their data transfer speed, and their reach. There are usually said to be three categories of networks: 1) LAN 2) MAN (metropolitan) 3) WAN (wide area network)
Q. Describe the main features of LAN and WAN
LAN:
1) Limited geographic operation
2) High speed data transfer rates
3) Full time connectivity to local services
4) Generally lower in cost than a WAN
5) Cabling is primary transmission medium
WAN:
2) High speed data transfer rates
3) Full time connectivity to local services
4) Generally lower in cost than a WAN
5) Cabling is primary transmission medium
WAN:
1) Referred as a large network.
2) Location is defined as any connection from one LAN to another 3) Point-to-Point connections.
4) Group of routers/switches connected not owned by one company.
5) Each groups' administrators maintain their part of the connections.
Q. LAN, MANs, WAN and Internet, intranet
LAN: A local area network (LAN) supplies networking capability to a group of computers in close proximity to each other such as in an office building, a school, or a home. A LAN is useful for sharing resources like files, printers, games or other applications. A LAN in turn often connects to other LANs, and to the Internet or other WAN.
MAN: MANs (Metropolitan Area Networks) connect multiple geographically nearby LANs to one another at high speeds. Thus, a MAN lets two remote nodes communicate as if they were part of the same local area network. A MAN is made from switches or routers connected to one another with high-speed links (usually fibre optic cables).
WAN: A wide area network (WAN) is a geographically dispersed telecommunications network. The term distinguishes a broader telecommunication structure from a local area network (LAN). A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks. An intermediate form of network in terms of geography is a metropolitan area network (MAN).
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies.
intranet is the generic term for a collection of private computer networks within an organization. An intranet uses network technologies as a tool to facilitate communication between people or work groups to improve the data sharing capability and overall knowledge base of an organization's employees.
Q. Back-up strategy of a core banking system
A backup strategy that will ensure that your memories and other important data can survive even the most devastating of accidents. Be sure to keep in mind these three important concepts:
2) Location is defined as any connection from one LAN to another 3) Point-to-Point connections.
4) Group of routers/switches connected not owned by one company.
5) Each groups' administrators maintain their part of the connections.

Q. Back-up strategy of a core banking system
A backup strategy that will ensure that your memories and other important data can survive even the most devastating of accidents. Be sure to keep in mind these three important concepts:
1) Schedule backups. Backups aren't useful unless they occur regularly. You must back up your data on a timely schedule.
2) Ensure redundancy. Be sure to make one or more copies of your data. The best backup, probably, is a second hard disk, but you should also be copying your data to removable media such as writeable CD or DVD.
3) Go off-site. Keep a second backup of your data off-site, in a separate physical location. This location can be a family member's or friend's house, a bank safety deposit box, a drawer at work, and so on. It just can't be inside your house.
Q. Importance of Business Continuity Plan (BCP) for a bank
Business continuity planning involves developing a practical plan for how your business can prepare for, and continue to operate after an incident or crisis. A business continuity plan will help you to:
• identify and prevent risks where possible
• prepare for risks that you can't control
• Respond and recover if a risk (e.g. an incident or crisis) occurs.
Preparing a business continuity plan will help your business recover quickly if an incident does happen. You may not be able to predict every kind of incident that could threaten your business, but you can develop a plan that covers a range of incidents. To get the most out of a business continuity plan, you should include a schedule for testing and updating it, making sure you take into account any changes to your business, your industry, or the location you operate in. This guide explains how to develop, test and update a business continuity plan for your business.
