In a DRAM
Each NIC card is assigned a unique ________ that is burned into _________.
1. NIC is used to connect a computer to an Ethernet network.
2.The card usually contains the protocol control firmware and the Ethernet controller needed to support Medium Access control (MAC).
3. A MAC address is given to a network adapter. It is a hardware into the computer Network interface card (NIC) and is also unique.
4. It is a six-byte or 48-bit address that uniquely identifies the Ethernet-based connection.
Consider a memory chip with 24 address pins and 16 data pins. How many locations will it accommodate?
Address pins= 24 (is related to the number of memory locations)
Data pins= 16 (It is related to the size of the memory location)
So For 'N-Bits' address pins, the number of locations that will accommodate is 2N.
So For '24-Bits' address pins, the number of locations that will accommodate is 224.
Hence the correct answer is 224.
The storage capacity of a SONY pen drive is 16 GB. Here what does G mean in 16 GB?
The conversion of memory is given below.
1 TB = 1024 GB
1 GB = 1024 MB
1 MB = 1024 kB
1 kB = 1024 Byte
1 Byte = 8 bits
Both EPROM and EEPROM are
In a DRAM,
In a DRAM, a capacitor to store a bit of data is used along with a MOSFET (transfer device) which acts as a switch. The circuit is as shown –

What are the advantages of a programmable logic device (PLD) over fixed-function ICs?
1. Reduction in board space requirement.
2. Reduction in power requirement.
3. Design security.
Programmable logic device (PLD):
It is an IC with a large number of logic gates, which is programmed by software to perform a specific digital logic function. And it can be changed according to the application.
Examples: PLA, PAL, FPLA, PROM, GAL, FPGA, etc.
Fixed functional ICS:
It is an ICs in a compact form that is designed to perform for fixed logic applications and it can not be changed after manufacture.
Examples: IC-555, IC-741, Johnson counter, full adder, parallel adder, etc.
Advantages of PLD over fixed functional ICs:
So, the correct option is D.
How many address inputs are required to access 256 Bytes memory?
Address line: An address line is basically refers to a physical connection between a CPU/Chipset and memory. They specify which addresses to access in memory. When there are k address lines, then 2k memory word can be accessed.
Data line: Data lines provides the information to be stored in memory. It represents the number of bits in the word.
Here, it is given that memory unit size = 256 bytes
2k = 256
k = 8
How many bits are in a byte?
1. A bit is the smallest unit of storage.
2. A bit stores just a 0 or 1.
3. Computers are designed to store data and execute instructions in bit multiples called bytes.
4. One byte is equal to 8 bits.
EPROM is generally erased by using
EPROM (Erasable programmable read-only memory):
