RAM -
1. RAM is full form random access memory.
2. Ram is volatile.
3. Ram allows reading and writing.
4. It is expensive.
5. performs read and write functions.
6. Its parts are DRAM and SRAM.
ROM -
1. Rom is full form. Read-only memory.
2. It is non-volatile.
3. Allows reading only.
4. Rom is permanent storage.
5. It is cheap.
6. Its parts PROM and EPROM.
DRAM OF THE FEATURE -
1. DRAM - Dynamic random access memory.
2. It is made of tiny capacitors that leak electricity.
3. Requires a recharge every few milliseconds to maintain its data inexpensively.
4. Slower than SRAM.
5. Can storage many bits per chip.
6. Uses less power.
7. Used for main memory.
SRAM OF THE FEATURE IS -
1. SRAM - Static random access memory.
2. It is made of D- flip flops.
3. Holds its contents as long as power is available.
4. Faster than DRAM.
5. Can not storage many bits per chip.
6. Uses for more power.
7. generates more power.
8. Used for cache memory.
MACHINE LANGUAGE IS -
Machine language is a collection of binary digits or its that the computer reads and interprets.
Machine language is the only language a computer understands; it is almost impossible for humans to use because they consist entirely of numbers.
ADVANTAGE OF MACHINE LANGUAGE -
1 . Faster is execution as it deals directly with computers.
DISADVANTAGE OF MACHINE LANGUAGE -
1. difficult to understand and develop programs using machine language.
ASSEMBLY LANGUAGE { 2GL } -
A low-level language that allows a programmer to use abbreviations or easily remembered words instead of numbers.
The observations are called mnemonics; these mnemonics are opcode and operands.
FOR EXAMPLE - ADD, AX, BX, etc.
ADVANTAGE OF ASSEMBLY LANGUAGE -
1. Faster in execution as it deals directly with computers.
DISADVANTAGE OF ASSEMBLY LANGAUGE -
1. Writing a program in assembly language is more convert than machine language.
HIGH-LEVEL LANGUAGE IS -
A high-level language { HLL } is a programming language such as C, FORTRAN, AND PASCAL that enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are considered high-level because they are closer to human languages and further from machine languages.
ADVANTAGE OF HIGH-LEVEL LANGUAGE -
1. High-level language is much closer to human language, so it is more suitable to write code in a high-level language.
DISADVANTAGE OF HIGH-LEVEL LANGUAGE -
1. It takes additional translation time to translate the source to machine code.
WHAT IS FLOPPY DISK -
1. It is a magnetic storage device.
2. It is a square-shaped disk.
3. It has a low capacity of about 1.44MB.
4. The access time of floppy disks is low.
5. It is cheap.
WHAT IS COMPACT DISK -
1. It is optical storage medium.
2. It is a circular-shaped disk.
3. It is a much higher capacity of 700MB.
4. The access time of CD is high.
5. It is costly.
WHAT IS A HARD DISK -
1. It is a magnetic storage device.
2. It is a square-shaped disk.
3. Capacity of a hard disk is 1024MB million bytes.
4. It is located inside the computer case.
5. It is costly than the CD.
