Computer

The Central Processing Unit (CPU) executes instructions comprising a computer program, performing basic arithmetic, local logic, and input/output control operations. [Memory Trick: 'C'entral 'P'ower 'U'nit acts as the central brain of computing.]

Hypertext Transfer Protocol is an application layer protocol used for transmitting hypermedia documents, such as HTML pages. [Memory Trick: Websites are made of 'Hyper-links' and 'Text', 'Transfer'-able via 'Protocol' = HTTP.]

A byte is a unit of digital information that most commonly consists of eight bits. [Memory Trick: You take an 'E'ight-course 'B'ite (Byte) of data!]

Solid State Drives (SSDs) store data on microchips with no moving parts, delivering faster boot and read/write speeds over mechanical HDDs. [Memory Trick: 'Solid' storage built tight - no spinning plates, just lightning speed!]

The kernel is the core component of an OS, acting as the primary bridge between software applications and the physical hardware. [Memory Trick: Like a nut, the 'Kernel' sits at the center, holding all structural gears in sync!]

Port 80 is the default TCP/IP port used to transfer HTTP web pages, while encrypted traffic (HTTPS) uses port 443. [Memory Trick: To fetch a page, you dial '8-0' on the unencrypted telephone line!]

Internet Protocol is the set of rules routing packet data across the web to allow different computers to communicate. [Memory Trick: Your digital 'Internet Passport' = Internet Protocol (IP)!]

JavaScript is a high-level, lightweight programming language utilized universally alongside HTML and CSS to create dynamic browser interfaces. [Memory Trick: Browsers love to sip on the 'Java-Script' potion to make pages dance!]

A firewall acts as a security barrier, analyzing packet transfers to allow or block them according to pre-configured rules. [Memory Trick: A protective wall of 'Fire' blocks hackers from entering your local castle!]

A Trojan Horse misleads users of its true intent to gain access, echoing the ancient Greek trick on the city of Troy. [Memory Trick: A sneak attack hidden in a 'gift horse' envelope!]

SQL (Structured Query Language) is the industry standard database syntax used to query, update, and manage relational database schemas. [Memory Trick: Asking database tables for files is done by 'S'-eeking 'Q'-uick 'L'-ists!]

A modem modulates outgoing digital signals into analog waves and demodulates incoming analog waves into digital. [Memory Trick: 'MO'-dulator + 'DEM'-odulator = MODEM!]

A compiler scans the entire source program to output a standalone binary file optimized for a target CPU architecture. [Memory Trick: The 'Compiler' packs all code scripts into a unified 'compiled suitcase' before takeoff!]

The Domain Name System translates human-understandable hostnames (like google.com) into computational IP addresses. [Memory Trick: The 'Directory' mapping 'Names' to numeric 'Server' IPs = DNS!]

Linux is a free, monolithic, POSIX-compliant kernel used to build highly stable operating systems for servers, mainframes, and mobiles. [Memory Trick: 'Linus' built a rock-solid system core, named it 'Linux'!]

Because computers utilize binary base-2, storage files count increments in powers of two, making 1 MB equal to 2^10 or 1024 KB. [Memory Trick: Binary math climbs in ladders of '10-24' steps!]

HTTPS wraps standard HTTP transfers inside TLS/SSL cryptosystems to prevent snooping by third parties. [Memory Trick: Look for the padlock and 'S' for 'Secure' = HTTPS!]

A deadlock occurs when processes hold resources while requesting others locked by companion routines, causing a stall. [Memory Trick: Complete lockup like a 'deadly road block' where no car moves!]

Git is a distributed version control engine storing structural histories of code projects in repository snapshots. [Memory Trick: Git lets you track 'Get-it' right files, commits, and rollback branches!]

WAN spans large geographical areas, connecting multiple regional networks. The internet is the largest WAN. [Memory Trick: 'W'ide networks span the 'W'ide world map!]

A MAC address is a 48-bit identifier assigned to networking chips globally, ensuring unalterable node delivery. [Memory Trick: A physical stamp showing your machine's 'M'-ake 'A'-nd 'C'-ode!]

HTML outlines headings, sections, text, links, and forms on web interfaces using markup tags. [Memory Trick: The essential structural 'H'-ouse framework 'T'-o 'M'-arkup 'L'-ayouts!]

MD5 outputs a 128-bit hash value, but can generate matching hash results for distinct inputs (collisions), making it insecure. [Memory Trick: 'M'edium 'D'amaged '5'-th grade algorithm = MD5!]

RAM holds immediate instructions and parameters for active processes, losing its entire payload when powered down. [Memory Trick: Active apps 'R'-un 'A'-live in 'M'-emory!]

A 404 code is returned by web servers when they cannot locate the file or route requested by user clients. [Memory Trick: '404' points to an empty, missing drawer slot in the server!]
