5 layers of TCP App
*DHCP-The Dynamic Host Configuration Protocol (DHCP) is a set of rules used by a communications device such as a computer, router or network adapter to allow the device to request and obtain an IP address from a server which has a list of addresses available for assignment.
*DNS-the domain name system (DNS) stores and associates many types of information with domain names; most importantly, it translates domain names computer hostnames to IP addresses.
*IRC-Internet Relay Chat (IRC) is a form of real-time Internet chat or synchronous conferencing. It is mainly designed for group many-to-many communication in discussion forums called channels, but also allows one-to-one communication and data transfers via private message.
*SIP-The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences."
*NNTP-The Network News Transfer Protocol or NNTP is an Internet application protocol used primarily for reading and posting Usenet articles, as well as transferring news among news servers.

What is Active Directory?
*Active Directory is an implementation of LDAP directory services by Microsoft for use in Windows environments. Active Directory allows administrators to assign enterprise-wide policies, deploy programs to many computers, and apply critical updates to an entire organization

What is NetBios/NetBeui
What is NetBIOS?
*NetBIOS is an acronym for Network Basic Input/Output System. The NetBIOS API allows applications on separate computers to communicate over a local area network.
What is NetBEUI?
*NetBIOS Extended User Interface is an unrouted network- and transport-level data protocol most commonly used as one of the layers of Microsoft Windows networking.
How does it work? TCP/IP
*In modern networks, it normally runs over TCP/IP (NBT), giving each computer in the network both a NetBIOS name and an IP address corresponding to a (possibly different) host name.

Tools and System Restore
*Scan Disk-is used to check your hard drive for errors. If it finds an error, it attempts (usually successfully) to fix it.
*Disk cleanup-is a small disk utility designed to clear previously deleted files. Deleting a file will normally just remove the file's directory entry, but the data itself still remains on the disk. CleanUp will completely eliminate the contents of your deleted files.
*Defragmenter-is a computer program designed to increase access speed (and sometimes increase the amount of usable space) by rearranging files stored on a disk to occupy contiguous storage locations.
*Backup-in computer engineering refers to the copying of data for the purpose of having an additional copy of an original source. If the original data is damaged or lost, the data may be copied back from that source, a process which is known as Data recovery or Restore.
*What is system restore?
System Restore-is a component of Microsoft's Windows Me and Windows XP operating systems that allows for the rolling back of system files, registry keys, installed programs, etc., to a previous state in the event of a failure.

What are the 2 components inside boots sector?
What is MBR?
*A master boot record (MBR) is the first sector ("sector zero") of a data storage device such as a hard disk. It is sometimes used for bootstrapping operating systems, sometimes used for holding a disc's partition table, and sometimes used for uniquely identifying individual disc media; although on some machines it is entirely unused and ignored.

What is the speed of it?
*100 mbs
What is the switch?
Switch- is a computer networking device that connects network segments. It uses the logic of a Network bridge but allows a phyisical and logical star topology. It is often used to replace network hubs.
