A microprocessor can directly process machine code but most programmers almost never write in it.

i am not sure but I think it is lan
Answer:
1. E.eid ,E.hobby, E.sal, E.did
2.E.eid , E.sal, E.hobby ,E.did , D.did, D.floor ,D.dname , D.budget.
3.E.eid , E.sal, E.hobby ,E.did , D.did, D.floor ,D.dname , D.budget.
4.E.eid , D.dname
Explanation:
The attributes that are examined for the query are the attributes of the table that are mentioned in the select statement and where clause.
So according to first query we are working on all attribues of Emp table so all of the attributes of Emp table are examined.In second query we selecting all attributes of both the tables hence all attributes of both the table and same in the next query.
In fourth query though the query is not complete where clause is missing but we have eid from Emp and dname from Dept tables for sure and the attributes mentioned in where clause will also be present.
Answer:
Internal and External Zones
Explanation:
Demilitarized Zone (DMZ) in a network means that, we make sure the security of network at higher level as military make sure the security of their bases or zones.
In this type of network, The network of the internal organization (LAN) needs security from hackers and unauthorized users who are trying to access the resources and information from the network.
This network is divided into two major zones. A DMZ has been placed between two zones along with firewalls enhance the security of LAN Network from the networks on internet. These two zones are named as Internal and External Zone. The firewall between DMZ and External zones monitors the users from external networks on the internet who tries to access organization's network. Internal network monitors the traffic between DMZ and Internal LAN network.
