Answer:
DDR
Explanation:
DDR is a feature of memory. It means a double data rate and is a more sophisticated version of the SDRAM, which is a memory. And the rest like the Multicore, 64-bit processing, and the L1 cache are the features of the CPU. And hence, the correct option here is none other than DDR. Remember that the L1 cache is the memory bank, which is being built over the CPU chip. And we have 32 bit and 64-bit processing for the CPU. As well as CPU can be dual-core, quad-core and likewise.
Answer: A. A method of access control that allows a user to log on to a system and gain access to other resources within the network via the initial logon
Explanation: key distribution center ( KDC) is a system that is used to provide access to a particular network user who shares data which are either private or regarded as sensitive.
It is a form of encryption that allows multiple system within the same network through the use of uniquely secured tickets used to setup a secure connection which gives room for data to be shared.
KDC makes use of cryptographic techniques to prove the validity of a user and grants a ticket permission access. The user present the ticket of permission to the system which then validates it and grant access to the user.
Example of security system that adopts KDC include kerberos.
